Abstract

During surgical removal of a pituitary adenoma, conduction in the anterior visual pathways was monitored by continuous recording of visual evoked responses (VER). The method employed a scleral contact lens with an embedded flashing diode for delivery of visual stimuli. Evoked potentials of nearly normal latency, amplitude, and form were recorded from occipital scalp electrodes immediately after the optic nerves were decompressed. Restoration of the VER was correlated with restoration of normal vision.

HMGA proteins up-regulate CCNB2 gene in mouse and human pituitary adenomas.

The high mobility group As (HMGAs) belong to a family of nonhistone nuclear proteins that orchestrate the assembly of nucleoprotein complexes. Through a complex network of protein-DNA and protein-protein interaction, they play important roles in gene transcription, recombination, and chromatin structure. This protein family is involved, through different mechanisms, in both benign and malignant neoplasias. We have recently reported that transgenic mice carrying the Hmga1 or Hmga2 genes under transcriptional control of the cytomegalovirus promoter develop pituitary adenomas secreting prolactin and growth hormone. We have shown that the mechanism of the HMGA2-induced pituitary adenoma is based on the increased E2F1 activity. The expression profile of mouse normal pituitary glands and adenomas induced in HMGA transgenic mice revealed an increased expression of the ccnb2 gene, coding for the cyclin B2 protein, in the neoplastic tissues compared with the normal pituitary gland. Here, we show, by electrophoretic mobility shift assay and chromatin immunoprecipitation, a direct binding of HMGA proteins to the promoter of ccnb2 gene, whereas luciferase assays showed that HMGAs are able to up-regulate ccnb2 promoter activity. Finally, we report an increased CCNB2 expression in human pituitary adenomas of different histotypes that is directly correlated with HMGA1 and HMGA2 expression. Because cyclin B2 is involved in the regulation of the cell cycle, these results taken together indicate that HMGA-induced cyclin B2 overexpression gives an important contribution to experimental and human pituitary tumorigenesis.

[A case of Cushing's disease associated with a non-functioning adrenal tumor].

A 52-year-old woman was admitted to our hospital for further examination of central obesity, hypertension and hirsutism suggesting Cushing's syndrome. Hirsutism had been remarkable for two years, and muscle weakness of the lower extremities gradually developed during the past year. CT scan revealed a tumor in the left adrenal gland which was 1 cm in diameter, round, well-circumscribed, homogeneous and not enhanced. Endocrine data disclosed increased urinary 17-OHCS (11.5-16.4 mg/day) and elevated plasma ACTH (125 pg/ml) and cortisol (19 micrograms/dl) with a lack of diurnal rhythm. Administration of the single-dose dexamethasone (1mg) did not suppress plasma cortisol. However, consecutive administration of either 2mg or 8mg of dexamethasone for 2 days suppressed both plasma cortisol and urinary 17-OHCS. Administration of metyrapone raised both urinary 17-OHCS and plasma ACTH levels. Rapid ACTH test resulted in a hyperresponse of plasma cortisol. CRF injection raised plasma ACTH and cortisol. Bilateral adrenal glands were well demonstrated by 19-iodocholesterol (I-131) scintigraphy during the administration of dexamethasone. MRI with Gd-contrast revealed a microadenoma in the sella turcica. With the diagnosis of Cushing's disease, the microadenoma was removed by the transsphenoidal approach and adrenal function was normalized. However, the left adrenal tumor remained on CT scan but was not demonstrated by scintigraphy. These findings indicate that this is a very rare case of Cushing's disease which was associated with an unilateral non-functioning adrenal tumor.

Expression of p53 protein in invasive colorectal carcinomas of different histologic types.

BACKGROUND: This study was performed to determine whether morphologic differences of colonic cancer types can be related to different genotypes of these tumors. METHODS: Paraffin sections of 76 human invasive colorectal carcinomas were examined for the overexpression of p53 oncoprotein with the avidin-biotin complex-peroxidase staining procedure and CM-1 antiserum, which detects p53 protein in paraffin-embedded material. The tumors were categorized as mucinous (22 cases), most of which originated from adenomas, and nonmucinous, which were subdivided into carcinomas originating from adenoma-carcinoma sequence (ACS) (29 cases) and de novo (DN) carcinomas (25 cases). RESULTS: Nineteen DN carcinomas (76%), 21 ACS carcinomas (72%), and 8 mucinous carcinomas (36%) exhibited detectable amounts of p53 protein in the tumor cell nuclei. Strong overexpression of p53 protein coincided with a high percentage (> 40%) of stained nuclei in 40% of ACS and 48% of DN carcinomas versus 9% of mucinous tumors. The percentage of stained nuclei, intensity of staining, and distribution of the stained areas did not correlate with the grade of differentiation or the invasive edge of the tumors. Along with nuclear staining of the tumor area, a distinct perinuclear staining of normal epithelial cells adjacent to the tumor was observed in 48% of DN, 7% of ACS, and 9% of mucinous carcinomas. CONCLUSIONS: The current results, in combination with the recently published data on Ki-ras and c-myc alterations, indicate that mucinous carcinomas differ from nonmucinous colorectal carcinomas in their genetic lesions.
