Dynamic organisation of prolactin gene expression in living pituitary tissue.
Gene expression in living cells is highly dynamic, but temporal patterns of gene expression in intact tissues are largely unknown. The mammalian pituitary gland comprises several intermingled cell types, organised as interdigitated networks that interact functionally to generate co-ordinated hormone secretion. Live-cell imaging was used to quantify patterns of reporter gene expression in disper...
متن کاملProlactin secreting pituitary carcinoma.
A man with a prolactin secreting pituitary carcinoma was treated by surgery and radiotherapy. Persistent hyperprolactinaemia partially responded to oral bromocriptine for four years. Serum prolactin then rose considerably with rapid, invasive tumour recurrence. Cytotoxic chemotherapy halted tumour progression for twelve months before fatal spread throughout the brain. Failure to normalise serum...
متن کاملProlactin & Prolactin Signaling Pathways in Cancer Risk & Tumorigenesis
Prolactin, or luteotropic hormone, is a single polypeptide chain that is best known to initiate and sustain lactation, maintain the corpus luteum, and stimulate growth and differentiation of breast tissue. A versatile and potent molecule, it is known to have more than 300 functions in the body. Prolactin is structurally similar to growth hormone and is involved in mediating communication among ...
متن کاملProlactin Secreting Pituitary Adenomas
Correspondence to: Ioana Muntean, e-mail: [email protected] ABSTRACT. Hyperprolactinemia has different etiologic forms, among them, the prolactin-secreting pituitary tumors represent an important entity. In our study, were analyzed the clinical aspects, diagnostic procedures and therapeutical approach of 31 cases of prolactinomas (F/M ratio = 27/4) hospitalized in the Clinic of Endocrinol...
متن کاملMethylation mechanisms in pituitary tumorigenesis.
Methylation is essential for embryonic development, however aberrant methylation of CpG islands associated with the tumour suppressor genes (TSGs) and leading to gene silencing is found in numerous tumour types. The TSG p16/CDKN2A is involved in the genesis of many tumour types and frequent methylation of the CpG island of the p16/CDKN2A gene is associated with loss of protein expression in pit...
