Ovarian theca cells
Thecomas or theca cell tumors are benign ovarian neoplasms composed only of theca cells. Histogenetically they are classified as sex cord-stromal tumours. They are typically estrogen-producing and they occur in older women (mean age 59; 84% after menopause). (They can, however, appear before menopause. ) 60% of patients present with abnormal uterine bleeding, and 20% have endometrial carcinoma. WebAMP-activated protein kinase (AMPK) is a fuel sensor in glucose, lipid, and cholesterol metabolism. Using RT-PCR and Western blot, AMPK subunits mRNAs (α1/2, β1/2, and γ1/2) and proteins (α1/2 and β1/2) can be found in the hen preovulatory follicles and precisely in both granulosa and theca cells. These preovulatory follicles are organized in a hierarchy …
