Activity and expression of 15-hydroxyprostaglandin dehydrogenase in cultured chorionic trophoblast and villous trophoblast cells and in chorionic explants at term with and without spontaneous labor.
OBJECTIVE: The aim of this study was to investigate whether any changes occurred at term before and with labor in the 15-hydroxyprostaglandin dehydrogenase messenger ribonucleic acid level and in the 15-hydroxyprostaglandin dehydrogenase activity in cultured chorionic and villous trophoblast cells and in chorionic explants. STUDY DESIGN: Twelve placentas (labor group [vaginal delivery], n = 6; nonlabor group [elective cesarean delivery], n = 6) were collected. Chorionic trophoblast and villous trophoblast cells and chorionic disks were obtained, cultured, and incubated with 282-nmol/L prostaglandin F(2)(alpha). Medium was collected to measure the 13,14-dihydro-15-keto metabolite of prostaglandin F(2)(alpha), and the cells and disks were snap-frozen to quantify 15-hydroxyprostaglandin dehydrogenase messenger ribonucleic acid expression by Northern blot analysis. RESULTS: The formation of the 13,14-dihydro-15-keto metabolite of prostaglandin F(2)(alpha) was significantly lower in the labor group than in the nonlabor group for both sets of cultured cells and for chorionic explants. 15-Hydroxyprostaglandin dehydrogenase messenger ribonucleic acid expression was lower in the chorionic trophoblast cells and chorionic disks of the labor group than those of the nonlabor group. However, the 15-hydroxyprostaglandin dehydrogenase messenger ribonucleic acid level in the villous trophoblast cells did not differ between the labor and nonlabor groups. CONCLUSION: Prostaglandin metabolic activity in the chorion is reduced significantly at the time of labor.

The fusion protein MEN 11303 (granulocyte-macrophage colony stimulating factor/erythropoietin) acts as a potent inducer of erythropoiesis.
OBJECTIVE: A fusion protein made of human granulocyte-macrophage colony-stimulating factor (GM-CSF) and erythropoietin (EPO), referred to as MEN 11303, has been tested for biologic activity using mobilized CD34(+) cells. METHODS AND RESULTS: MEN 11303 and a combination of GM-CSF/EPO produced the same amount of colony-forming unit granulocyte-macrophage (CFU-GM), of burst-forming unit erythroid (BFU-E), and of multipotent CFU-mixed. After 15 days, liquid cultures of CD34(+) cells exposed to MEN 11303 yielded a total cell number larger than that obtained with an equimolar mixture of GM-CSF and EPO, with a clear prevalence of cells exhibiting an erythroid phenotype. A colony-forming cell assay established from CD34(+) cells precultured with MEN 11303 for 7 days yielded a greater amount of BFU-E than GM-CSF/EPO combination. Exposing CD34(+) cells to MEN 11303 for 7 days in liquid culture resulted in higher recoveries of cells expressing a comparatively less differentiated hematopoietic phenotype and of long-term culture initiating cells. A cell-based binding-competition assay using the human EPO-receptor (EPO-R) transfected murine Ba/F3EPOR cell line showed that MEN 11303 bound to EPO-R with a sixfold lower affinity but induced a more sustained receptor phosphorylation. MEN 11303 supported the growth of Ba/F3EPOR cells more efficiently than EPO and remained detectable in the spent culture medium for a longer time. CONCLUSIONS: MEN 11303 and the combination of GM-CSF/EPO are equally potent in recruiting hematopoietic progenitors into cycle, but the fusion protein is superior in promoting the expansion of committed erythroid percursors. Primitive hematopoiesis is less affected by MEN110303 than GM-CSF/EPO combination. Part of these effects may reflect the peculiar interaction of the EPO moiety of MEN 11303 with the EPO-R.

CD34+/CD105+ cells are enriched in primitive circulating progenitors residing in the G0 phase of the cell cycle and contain all bone marrow and cord blood CD34+/CD38low/- precursors.
A subset of circulating CD34+ cells was found to express CD105 antigen. Sorting experiments showed that most granulocyte-macrophage colony-forming units (GM-CFU) and burst-forming units - erythroid (BFU-E) were retained in the CD34+/CD105- fraction, whereas rare GM-CFU/BFU-E were generated from CD34+/CD105+ cells. Megakaryocytic aggregates were entirely retained in the CD34+/CD105+ fraction. Neutralizing doses of an anti-TGF-beta1 antibody demonstrated CD34+/CD105+ cells capable of colony-forming activity without any significant effect on CD34+/CD105- cells. Cloning of secondary colonies revealed that CD34+/CD105+ cells had a significantly higher secondary cloning efficiency than CD34+/CD105- cells. CD34+/CD105+ cells had a significantly higher long-term culture-initiating cell (LTC-IC) frequency than CD34+/CD105- cells. Kinetic analysis showed that 75% of CD34+/CD105+ cells consisted of DNA 2n G0Ki-67- cells whereas 82% of CD34+/CD105- were DNA 2n G1Ki-67+ cells, and this latter subset showed a RNA content consistently higher than CD34+/CD105+ cells. CD34+/CD105+ progenitors were CD25+, whereas CD34+/CD105- contained a small CD25+ subset. Three-colour analysis of bone marrow and cord blood CD34+ cells demonstrated that all the CD34+/CD38low/- primitive precursors were contained in CD34+/CD105+ cells. Extensive characterization of these CD105+ precursors indicated that they have biological properties associated with primitive haematopoietic precursors.

High cyclin-dependent kinase inhibitors in Bcl-2 and Bcl-xL-expressing CD34+-proliferating haematopoietic progenitors.
We have previously described the isolation of primitive, slow-proliferating progenitors from normal, circulating CD34+ cells by using the fluorescent dye 5-6-carboxyfluorescein diacetate succinimidyl ester (CFDA-SE). CFDA-SE(bright) (primitive) and CFDA-SE(dim) (differentiating) cells were isolated following cytokine stimulation on the basis of their different proliferation rates. In the present work we analysed the expression levels of a number of proteins involved with differentiation, proliferation and survival/apoptosis in CFDA-SE(bright)/CD34+/slow-proliferating cells that were previously defined as progenitors capable of differentiating into different lineages. The aim of this work was to gain a better understanding of our model system in order to define some of the important parameters that regulate differentiation in haematopoietic progenitors. GATA-1 and PU.1 RNA levels were similar in freshly isolated (d 0) CD34+ and in CFDA-SE(bright) (bright) cells, whereas they increased in CFDA-SE(dim) (dim) cells. Accordingly, Nm23 was expressed at higher levels in bright cells. Moreover, bright cells had higher p21WAF1/CIP1, p27KIP1 and p16Ink4 protein levels than dim cells. Consistently, Cdc2 and Cdk2 kinase activity was much higher in the dim than in the slower proliferating bright cells. C-myc and p53 levels were higher in bright cells than in d 0 CD34+ and dim cells, and so was Bcl-xL, which followed the trend we have previously described for Bcl-2. Thus, bright cells, despite having a higher proliferation rate than the starting d 0 CD34+ population, have strikingly elevated levels of cyclin-dependent kinase inhibitors, which are likely to also act as inhibitors of differentiation.

Antitumour activity of novel taxanes that act at the same time as cytotoxic agents and P-glycoprotein inhibitors.
Taxanes antitumour agents such as paclitaxel and docetaxel represent a successful family of chemotherapeutic drugs. Unfortunately, acquired and innate resistance represents a clinical problem for these drugs. We investigated, on a panel of 7 human cancer cell lines, the growth inhibition effect of 3 newly developed taxanes (SB-T-1213, SB-T-1250 and SB-T-101187) with modification at the C10 and C3' positions of the taxane framework. These positions have been previously characterized as critical to make taxanes highly active against cells overexpressing the efflux pump P-glycoprotein (P-gp). Paclitaxel and docetaxel were used as reference compounds. Results unambiguously indicate the exceptional activity of the novel taxanes toward P-gp positive cells (up to >400 fold higher potency than that of paclitaxel). SB-T-1213 and SB-T-1250 are also substantially more active than the reference compounds against P-gp negative cells. To better understand the mechanisms underlying the enhanced activity of the newly developed taxanes, we performed cell cycle and apoptosis analysis. This study demonstrates that the striking growth inhibition effect exhibited by the novel taxanes is ascribed to their increased ability in inducing apoptosis and G(2)/M cell cycle block. SB-T-1213 and SB-T-1250 are also more active than reference compounds in inducing intracellular accumulation of the beta-tubulin subunits. Finally, it is revealed that these novel taxanes have ability to inhibit the function of the P-gp efflux pump on the basis of the Rhodamine 123 assay. These findings strongly suggest that SB-T-1213, SB-T-1250 and SB-T-101187 represent a new tool to overcome innate or acquired P-gp mediated taxane-resistance.

Antibodies to human herpes virus type 8 (HHV8) in general population and in individuals at risk for sexually transmitted diseases in Western Sicily.
BACKGROUND: Human herpes virus 8 (HHV8) appears to be the primary aetiologic agent of Kaposi sarcoma (KS). To study the distribution of HHV8, a seroepidemiological study was carried out in western Sicily, where a high incidence rate of classical KS is well documented. METHODS: A total of 970 sera of healthy human immunodeficiency virus (HIV) negative individuals of general population (1-70 years old) and 742 sera of individuals in different risk groups for HIV infection were evaluated by means of an indirect immunofluorescence assay able to detect antibodies to lytic and latent HHV8 antigens. RESULTS: Crude seroprevalence to HHV8 antigens was 11.5% in the general population, and it increased significantly with age from 6% under age 16 to 22% after age 50. Significantly higher HHV8 seroprevalence rates were detected among HIV positive and negative homosexual men (62% and 22%, respectively), men who had sex with prostitutes (40% and 29%, respectively); female prostitutes (42% and 30%, respectively), and clients at a sexually transmitted disease clinic (male: 60% and 33%, respectively, female: 63% and 43%, respectively). In contrast, heterosexual intravenous drug users had seroprevalence rates comparable to those found in the general population. CONCLUSIONS: The results suggest that HHV8 infection is widespread in Western Sicily. The high seroprevalence in individuals with high risk sexual activity point to the role of sexual behaviour in the transmission of the infection in adults, whereas the detection of antibodies in younger population (under 16 years old) is suggestive of a non-sexual route of transmission, probably occurring during childhood by close personal contact.

Bcl-2, Bax, Bcl-x(L) and Bcl-x(S) expression in neoplastic and normal endometrium.
The two anti-apoptotic proteins Bcl-2 and Bcl-x(L), and the two pro-apoptotic proteins Bax and Bcl-x(S) were measured by Western blotting in 51 neoplastic and 8 normal endometrial samples. The corresponding mRNA levels were analyzed by semiquantitative reverse transcriptase-polymerase chain reaction in a subgroup of 19 endometrial carcinomas. Neoplastic tissues had higher amounts of Bcl-2 protein than normal tissues (p < 0.051). Bcl-x(L) followed the same trend since its levels were higher in tumor than in normal samples (p < 0.048). Interestingly, Bcl-2 and Bcl-x(L) protein content showed a trend towards an inverse correlation (r = 0.27, p < 0.052). mRNA and protein levels directly correlated only with Bcl-2 (r = 0.63, p < 0.0032). Despite the fact that the amounts of Bcl-2, Bax and Bcl-x(L) proteins in the neoplastic population were not significantly differently distributed according to the clinicopathological features of the patients, the differences observed between normal and neoplastic samples suggest that these proteins may play a role in endometrial carcinoma: long-term follow-up studies will be required to confirm this hypothesis.

Antagonistic effect of the combination gemcitabine/topotecan in ovarian cancer cells.
The in vitro interaction between the new antimetabolite gemcitabine (GEM) and topotecan (TPT) was analyzed in A2780 ovarian cancer cells. The growth inhibitory effect was assessed after 3 days of drug exposure. GEM and TPT obtained in vitro IC50 values of 2.1 +/- 0.9 and 33.7 +/- 10.2 nM, respectively. The interaction between GEM and TPT was evaluated by exposing cancer cells at increasing doses of GEM (0.1, 1, and 10 nM) and TPT (1, 10, 100, and 1000 nM). Analysis of data about the interaction between GEM and TPT was performed by applying the isobole method. An antagonistic effect was noticed when GEM was combined with TPT in the tested concentration range. DNA analysis was also performed and showed an augmentation of cells blocked in the G2/M phase during TPT exposure, while an increase of blocked cells in the G0/1, phase was observed after GEM treatment. This latter effect was predominant when the two drugs were used in combination. We also investigated the effect of sequential exposure to drugs, pretreating A2780 cells for 24 h with TPT and then for 48 h with GEM, and, conversely, pretreating A2780 cells with GEM for 24 h and thereafter with TPT for 48 h. Both these combined sequential treatments showed an antagonist effect of the drugs' combination. Long-term growth inhibition effect was established by clonogenic assay performed after 10 days of culture after drug treatment. Also these data confirmed the antagonistic effect between GEM and TPT in A2780 ovarian cancer cells.

Growth inhibitory effects and radiosensitization induced by fatty aromatic acids on human cervical cancer cells.
Evidences have been reported that phenylacetic (PA) and phenylbutyric (PB) fatty aromatic acids can exert tumor growth inhibition in vitro and in vivo. Moreover, clinical trials also showed some activity for these drugs to modulate the expression of genes implicated in tumor growth, metastasis, immunogenicity, and to potentiate the efficacy of cytotoxic agents. The aim of the study was to examine the effects of PA and PB on the growth as well as sensitization to cisplatin and radiation in human cervical cancer cells. The effects of PA and PB on the proliferative activity and apoptosis induction in cervical tumor tissue was investigated. Both PA and PB exhibited a time- and dose-dependent antiproliferative activity in SW756 and ME180 cell lines: after 72-h treatment, the IC50 (concentration able to inhibit 50% of cell growth) of PB was 1.9 +/- 0.2 mM and 1.5 +/- 0.2 mM in SW756 and ME180 cells, respectively, while the IC50 of PA was 13.0 +/- 1.7 mM and 10.0 +/- 1.2 mM in SW756 and ME180 cells, respectively. In tumor tissue biopsies obtained from patients affected by squamous cervical cancer, both drugs resulted in a marked reduction of the percentage of bromodeoxyuridine-labeled cells compared with untreated samples [19.0 +/- 1.63% in untreated tissues with respect to 1.30 +/- 0.54% and 4.20 +/- 2.50% of stained cells after treatment with PA (30 mM) (P < 0.0001) and PB (5 mM) (P < 0.0001), respectively]. Moreover, analysis of the staining with M30 monoclonal antibody revealed that PA (30 mM) and PB (5 mM) were able to produce a marked increase in the number of stained apoptotic nuclei with respect to untreated samples. Finally, PB and PA were shown to enhance the sensitivity of SW756 to radiation and to exert an additive effect when combined with cisplatin. A significant reduction of the processed form of p21ras and rhoB proteins in the membrane fraction of cells exposed to PA and PB was observed. When farnesol, which is able to circumvent the enzymatic step inhibited by PA and PB, was added to the medium only a partial reversal of the growth inhibition and potentiation of sensitivity to radiation induced by PA and PB were found. In conclusion, the growth inhibitory properties of fatty aromatic acids suggest that these molecules could represent the prototype of a new class of compounds with some therapeutic potential in cervical cancer.

p21WAF1/CIP1 protein expression in primary ovarian cancer.
p21WAF1/CIP1 protein is a cyclin-dependent kinase inhibitor, able to prevent the CDK2/cyclin E induced retinoblastoma protein (pRB) phosphorylation, thus inhibiting cell cycle progression at G1 phase. p21WAF1/CIP1 protein levels were examined in a series of 102 ovarian tissue samples including normal ovary, primary ovarian tumors, omental metastasis, recurrent disease and residual tumor after chemotherapy exposure, by Western blot analysis. The association of p21WAF1/CIP1 status with clinicopathological parameters and clinical outcome was also investigated. p21WAF1/CIP1 protein was detectable in 76 out of 102 (74%) ovarian tissue samples. We observed a significant trend of p21 levels to gradually increase from normal ovarian tissues (median 0 a.u.) through primary ovarian cancers (median 0.19 a.u.), omental metastases (median 0.33 a.u.) and recurrence of disease (median 0.44 a.u.) (p=0.015). In the group of stage III-IV ovarian cancer patients, p21-positive cases showed a more favourable prognosis with respect to p21-negative cases: the 3-year time to progression (TTP) rate was 58% for p21-positive compared with 33% of p21-negative cases (p=0.036). In conclusion, p21WAF1/CIP1 expression levels seem to be correlated with tumor status at the time of diagnosis and can predict TTP in a selected group of patients.

Emergency cerclage in the presence of protruding membranes: is pregnancy outcome predictable?
BACKGROUND: The aim of this retrospective study is to verify whether some maternal features are related to pregnancy outcome in cases of emergency mid-trimester cerclage when membranes are protruding through the dilated cervix. METHODS: Between 1988 and 1996 twenty-three pregnant patients with dilated cervix and protruding membranes were treated with emergency cerclage. At the time of cerclage, gestational age ranged from 17 to 27 weeks (median 22). RESULTS: Pregnancy was prolonged from 0 to 20 weeks (median 4). Eleven living infants were born (46%); median gestational age at delivery was 25 weeks (range 21-39) and median birth weight 700 g (range 350-3980 g). Obstetric histories, white blood cell count, and vaginal-cervical and urine cultures obtained on admission were analyzed in the two following groups: data from patients with good pregnancy outcome (live births) versus those from patients with poor outcome (stillbirths and neonatal deaths). No significant difference was found between the groups for the above mentioned maternal features. CONCLUSIONS: The possibility of 46% live births is considered a good result for mid-trimester emergency cerclage when the membranes are protruding. Success of the procedure remains unpredictable on the basis of the maternal features investigated.

p27Kip1 expression is associated with clinical outcome in advanced epithelial ovarian cancer: multivariate analysis.
Few biological parameters have been shown to have a prognostic role in patients with advanced ovarian cancer. p27Kip1 is a cyclin-dependent kinase inhibitor, and its loss may contribute to tumor progression. We determined whether p27Kip1 protein expression in advanced ovarian cancer could be associated with prognosis. p27Kip1 status was assessed by immunohistochemical analysis of tissue sections from primary tumors of 99 patients with stages III-IV ovarian carcinoma and was analyzed in relation to clinicopathological variables, time to progression (TTP), and overall survival (OS). p27Kip1 expression was detected in 47 (47%) of the 99 patients. p27 expression did not correlate with any of the classical clinicopathological parameters. Loss of p27 protein was significantly associated with a short TTP (P = 0.0004) and decreased OS (P = 0.0302). The 5-year TTP rate in p27-positive patients was 50% versus 11% in p27-negative patients. p27-positive cases showed a 5-year OS rate of 53% compared with 43% of p27-negative cases. In multivariate analysis, p27 expression was an independent predictor of progression of disease (P = 0.0009) and survival (P = 0.0032) when considered together with stage of disease, presence of ascites, and residual tumor at surgery. Loss of p27Kip1 conferred poor prognosis independently of proliferative index, as assessed by proliferating cell nuclear antigen immunostaining. p27 immunoreactivity can be used to predict progression of disease and survival in patients with advanced epithelial ovarian cancer and therefore may represent a new prognostic marker.

Expression of bcl-2, bax-xL, and bcl-xS in endometrial and cervical tissues.
We assessed the protein expression levels of bcl-2, bax, bcl-xL, and bcl-xS in a group of 51 endometrial cancers and 8 normal samples as well as in 59 cervical neoplasms and in 15 normal cervical tissues. Neoplastic endometria (median, 1.30 absorbance units [AU]; range, 0.13-7.26 AU) had slightly higher bcl-2 levels than did normal tissue (median, 0.83 AU; range, 0.29-1.90 AU; P < .068), whereas bcl-2 was lower in neoplastic (median, 3.59 AU; range, 0.13-19.86 AU) than in normal cervical samples (median, 8.45 AU; range, 2.09-15.04 AU; P < .010). Bcl-xL levels were higher in endometrial carcinoma (median, 1.23 AU; range, 0.03(4.29 AU) than in normal tissues (median, 0.56 AU; range, 0.46-1.48 AU; P < .048), whereas no significant difference was observed in cervical tissues. Bax levels did not show any variation in either system. The protein bcl-xS was marginally detectable in only a few samples. In endometrial carcinoma, bcl-2 and bcl-xL levels were correlated inversely (r = -0.27; P < .054), whereas in cervical cancer, they were correlated directly (r = +0.40; P < .002). The different expression patterns of bcl-2 family members in endometrial and cervical tissues confirm the hypothesis of a strictly tissue-specific regulation of these proteins.

[Quaternary ammonium salts in gynecology and obstetrics].
We have summarized chemical, physical, and microbiological characteristics of Quaternary Ammonium Salts: particularly, benzalchromium chloride and didecyl-dimethyl-ammonium chloride characteristics were analyzed. These compounds may act as antimicrobial agents in different way: 1) they are surface-active agents and will denature protein or cause dissociation of an enzyme from its prosthetic group; 2) they may alter the cell permeability of bacteria and yeasts; 3) they may stimulate the glycolysis reaction and 4) may inhibit oxidation of lactate. These latest activities may play a role in maintenance of physiologic microbial ecology of vagina or in the re-establishment of the vaginal ecosystem after vaginitis or vaginosis. We have also summarized the physiologic variation of vaginal ecosystem during the different phases of women's life and the microbiology of vagina during vaginitis and vaginosis. The results of more recent studies about the therapeutic role of quaternary ammonium compounds in vulvo-vaginal infections an in vaginosis are synthetically reported. We concluded that quarternary ammonium compounds are efficacious, handy and safe, in obstetrics and gynecology. A very good compliance and low costs of these compounds suggest that they may be used alone as well in association with specific antimicrobial agents in the treatment of most of gynecological infections, and particularly in bacterial vaginosis.

Frequent loss of expression of the cyclin-dependent kinase inhibitor p27 in epithelial ovarian cancer.
p27Kip1 is a member of the Cip1/Kip1 family of cyclin-dependent kinase inhibitors and is a potential tumor suppressor gene. Low levels of p27 are associated with poor prognosis in a variety of tumors, including breast, colon, prostate, and lung carcinomas. In the present study, p27 protein expression was investigated by immunohistochemistry and Western blot analysis in a series of 82 epithelial ovarian tumors [16 classified as low malignant potential (LMP) and 66 classified as primary ovarian adenocarcinomas]. Immunohistochemical analysis revealed frequent loss of p27 expression in primary ovarian adenocarcinomas (33%), with respect to LMP tumors (6%; P = 0.0009). In addition to nuclear staining, cytoplasmic localization of p27 was noted in 45 (55%) of 82 cases. p27 levels inversely correlated with cdk2 kinase activity in a representative subset of tumors. When the clinical outcome of the patients was evaluated in relationship to p27 status, we observed a significant correlation between presence of p27 staining and a longer time to progression (P = 0.032 by log-rank test). These data indicate that loss of p27 is a frequent event in ovarian carcinomas as compared with LMP tumors, suggesting that these tumor types may have different pathogenesis. p27 levels may also represent a useful prognostic marker for predicting disease recurrence in primary ovarian carcinomas.

Ontogeny of the fetal immune system: study on pregnancies with Rh-isoimmunization and nonimmune fetal hydrops.
This study aims at observing and comparing the antigen expression of some fetal T- and B-lymphocyte subpopulations in Rh-isoimmunization, which determines anemic hypoxia in the fetus, and nonimmune fetal hydrops (NIFH) which, even if there are some etiological factors involved, causes hipoxic hypoxia in the fetus. Twelve fetuses were studied by way of 30 fetal blood samples obtained by ultrasound-guided cordocentesis between the 20th and 36th gestational week. Twenty-four blood samples in all where taken from the eight fetuses with Rh-isoimmunization. Six blood samples were obtained from the four fetuses with NIFH. The lymphocyte phenotypes studied by monoclonal antibodies and flow cytometry were the following: CD3, CD4, CD8, expression of T-lymphocyte subpopulations; BsIg, CD19, expression of B-lymphocyte subpopulations. We observed a near-normal maturation process in fetuses with Rh isoimmunization, whereas in fetuses with NIFH we observed inhibition and/or delayed expression of T-lymphocytes. An early and increased B-lymphocyte activation marked a cooperation between the two systems in the early gestational periods.
