The document discusses a study that found expression of the follicle-stimulating hormone (FSH) receptor in blood vessels surrounding tumors, including breast, prostate, and testis tumors. The researchers used techniques like immunohistochemistry, fluorescence in situ hybridization (FISH), immunoprecipitation, and Western blotting to identify and characterize the FSH receptor in these tumor blood vessels. Their results suggest FSH may stimulate proliferation and maturation of tumor cells by signaling through receptors on surrounding blood vessels.

2. INTRODUCTION

3. FSH Is a hormone that is produced in the anterior pituitary gland. In females: FSH stimulates follicular maduration and estrogen . In males: FSH stimulates Sertolli cell proliferation spermatogenesis

4. TUMOR

5. They are anormal celular proliferation at the blood vassels cells BLOOD VESSELS TUMOR

7. FSH receptor is known to be expressed only in the testicular sertolli cells and the ovarian granulosa cells. But acording to the study the FSH positive receptor expression was localizated in blood vessels surrounding the tumor (EX: breast , prostate and testis tumor) In consecuence FHS can stimulate the proliferartion and maturation of those tumor cells.

21. DISCUSSION

22. DISCUSSION Author What he say Agree or disagree Mariani S,Ben –Josef, et al. “ two previous studies showed immunohistochemical detection of the FSH receptor in the tumor cells of prostate adenocarcinomas” Alam H, et al. “ the binding of FSH to FSH receptor in ovarian granulosa cell induces an increase in hypoxia-inducible factor 1alfa protein levels under normoxic conditions, which in turn leads to up-regulation of vascular endothelial growth factor(VEGF)”

23. DISCUSSION Author What he say Agree or disagree Fox SB, et al. “ another possibbility is suggested by the observation that in the breast tumors in humans, endothelial cells proliferate at the tumor periphery but not in the interior” Castro-Fernández C, et al. “ the fact that FSH and FSH receptor signaling is known to generate activated Gq/11 protein”
