Abstract

We have developed a method for anchored amplification on a microchip array that allows amplification and detection of multiple targets in an open format. Electronic anchoring of sets of amplification primers in distinct areas on the microchip permitted primer-primer interactions to be reduced and distinct zones of amplification created, thereby increasing the efficiency of the multiplex amplification reactions. We found strand displacement amplification (SDA) to be ideal for use in our microelectronic chip system because of the isothermal nature of the assay, which provides a rapid amplification system readily compatible with simple instrumentation. Anchored SDA supported multiplex DNA or RNA amplification without decreases in amplification efficiency. This microelectronic chip-based amplification system allows multiplexed amplification and detection to be performed on the same platform, streamlining development of any nucleic acid-based assay.

Inhibition of histone deacetylase enhances the anti-proliferative action of antiestrogens on breast cancer cells and blocks tamoxifen-induced proliferation of uterine cells.

Here we report a novel potential therapeutic strategy using histone deacetylase (HDAC) inhibitors to enhance the action of hormonal therapy agents in estrogen receptor alpha (ER alpha)-positive breast cancer. HDAC inhibitors [trichostatin A (TSA), suberoylanilide hydroxamic acid (SAHA) and valproic acid (VPA)], inhibited proliferation of MCF-7 breast cancer cells and, in combination with tamoxifen inhibited proliferation better than with either agent alone. VPA, an anti-convulsant drug with HDAC inhibitory activity, enhanced tamoxifen action at doses within the concentration range used for anti-convulsive therapy. VPA cooperated with tamoxifen in a variety of ER alpha-positive cell lines and was also effective when combined with other antiestrogens, and with aromatase inhibition. VPA enhanced antiestrogen action by promoting cell death via apoptosis without affecting cell cycling. Some of this action may be due to VPA's ability to induce the pro-apoptotic gene Bik, which is also induced by antiestrogens. Remarkably, VPA blocked the undesirable pro-proliferative action of tamoxifen on uterine endometrial cells. Our in vitro results suggest that VPA and other HDAC inhibitors have the potential to enhance hormonal therapy for ER alpha-positive breast cancer and simultaneously reverse the adverse effects of antiestrogens in the uterus.

Gonadotrophin stimulation of non-luteinized granulosa cells increases steroid production and the expression of enzymes involved in estrogen and progesterone synthesis.

BACKGROUND: In regular IVF treatment, mature oocytes are collected with their luteinized granulosa cells (GCs). When in vitro maturation (IVM) of the oocytes is performed, non-luteinized GCs can be collected. We have investigated how these cells respond to gonadotrophin stimulation in culture. METHODS: GCs were collected from patients undergoing IVM treatment and compared with GCs from IVF patients. The cells were stimulated with FSH and/or hCG. After 48 h, culture media were collected for hormone analysis, and RNA was isolated for gene expression analysis. RESULTS: In IVM GCs, hCG and FSH alone and in combination induced significantly increased progesterone production, and FSH alone and in combination with hCG increased estrogen production. We also studied the gene expression of P-450aromatase and P-450scc and the receptors for FSH and LH. In non-luteinized GCs, the expression levels of P-450aromatase increased with all treatments, and P-450scc expression increased with the combined FSH and hCG treatment. LHR expression increased with FSH treatment, but the FSH receptor expression did not change with different treatments. CONCLUSIONS: Non-luteinized GCs behaved differently from luteinized GCs in culture. The data help understand the final stages of maturation of human oocytes and follicles.

Expression of aromatase, estrogen receptor alpha and beta, androgen receptor, and cytochrome P-450scc in the human early prepubertal testis.

The expression of aromatase, estrogen receptor alpha (ERalpha) and beta (ERbeta), androgen receptor (AR), and cytochrome P-450 side chain cleavage enzyme (cP450scc) was studied in prepubertal testis. Samples were divided in three age groups (GRs): GR1, newborns (1- to 21-d-old neonates, n = 5); GR2, postnatal activation stage (1- to 7-mo-old infants, n = 6); GR3, childhood (12- to 60-mo-old boys, n = 4). Absent or very poor detection of ERalpha by immunohistochemistry in all cells and by mRNA expression was observed. Leydig cells (LCs) of GR1 and GR2 showed strong immunostaining of aromatase and cP450scc but weak staining of ERbeta and AR. Interstitial cells (ICs) and Sertoli cells (SCs) expressed ERbeta, particularly in GR1 and GR2. Strong expression of AR was found in peritubular cells (PCs). For all markers, expression in GR3 was the weakest. In germ cells (GCs), i.e. gonocytes and spermatogonia, aromatase and ERbeta were immunoexpressed strongly whereas no expression of ERalpha, AR, or cP450scc was detected. It is proposed that in newborn and infantile testis, testosterone acting on PCs might modulate infant LC differentiation, whereas the absence of AR in SCs prevents development of spermatogenesis. The role of estrogen is less clear, but it could modulate the preservation of an adequate pool of precursor LCs and GCs.
