Bilateral ovarian capillary hemangioma with stromal luteinization and hyperandrogenism.
A 77-year-old female presented to the outpatient clinic with a six-month history of left lower quadrant abdominal fullness and pressure. Serum levels included free testosterone 3.8 pg/mL (normal 0-1.8 pg/mL) and testosterone 259 ng/dL (normal 3-41 ng/dL). Magnetic resonance imaging of the pelvis showed bilateral small ovarian cystic masses with marked, progressive enhancement, and restriction o...
متن کاملLipoprotein receptor expression during luteinization of the ovarian follicle.
Ovarian follicles luteinize after ovulation, requiring structural and molecular remodeling along with exponential increases in steroidogenesis. Cholesterol substrates for luteal steroidogenesis are imported via scavenger receptor-BI (SR-BI) and the low-density lipoprotein (LDL) receptor from circulating high-density lipoproteins and LDL. SR-BI mRNA is expressed in pig ovaries at all stages of f...
متن کاملNovel signaling pathways that control ovarian follicular development, ovulation, and luteinization.
The interactions of peptide and steroid hormone signaling cascades in the ovary are critical for follicular growth, ovulation, and luteinization. Although the pituitary gonadotropins follicle-stimulating hormone (FSH) and luteinizing hormone (LH) play key regulatory roles, their actions are also dependent on other peptide signaling pathways, including those stimulated by insulin-like growth fac...
متن کاملMolecular mechanisms of luteinization
Dynamic changes in steroidogenesis occur in ovarian granulosa cells during ovulation after the LH surge. The ovulatory LH surge induces rapid up-regulation of steroidogenic acute regulatory (StAR) protein and rapid down-regulation of aromatase (Cyp19a1) in granulosa cells undergoing luteinization during ovulation. These rapid changes in StAR and Cyp19a1 gene expression after the LH surge effici...
متن کاملProhibitin: targeting peptide coupled to ovarian cancer, luteinization and TGF-β pathways
BACKGROUND Ovarian epithelial tumor (OET) is a silent disease of late diagnosis and poor prognosis. Currently treatment options are limited and patient response to treatment is difficult to predict so there is a serious need to delineate the real pathogenesis to predict tumour prognosis. Prohibitin (PHB) is an evolutionarily protein that regulates the cell cycle. TGF-β has been shown to be a po...
