Transcript

  • 1. EXPRESSION OF FOLLICLE-STIMULATING HORMONE RECEPTOR IN TUMOR BLOOD VESSELS Aurelian Radu,Ph. D, et al Laura Andrea Gómez Marín ID 000144738 Felipe Lozano Pineda ID 000172651 Molecular Biology Medicine school III semester
  • 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
  • 6. http://www.google.com.co/images?hl=es&biw=1276&bih=557&gbv=2&tbs=isch%3A1&sa=1&q=BLOOD+VASSELS+TUMOR&aq=f&aqi=&aql=&oq= BLOOD VESSELS TUMOR CHARACTERISTICS
  • 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. RELATIONSHIP BETWEEN FSH AND TUMOR

  • 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”
  • 24. PERSONAL CONCLUSIONS
    • The possibility to know specifically the expression of TSH receptor will allow doctors improve techniques in order to reduced the risk of metastasis in blood vessels cells.
    • Thanks to the developing of inmublotting, inmunohistochemical and the FSH-receptor purified antibodies techniques many diseases can be detected faster, in that way patients would have more chances to survive
  • 25. PERSONAL CONCLUSIONS
    • This kind of investigations give more alternatives on diagnosis and treatment to the medical society in order to focus properly each of different diseases existing
    • The topic was interesting, also is something that we are learning at this moment so that aspect made us the workshop more understandable and more applicable to our low knowledge in medicine.
