OBJECTIVE To demonstrate whether leptin modulates reproduction by a direct effect within the ovary. DESIGN Animal model. SETTING National Key Laboratory of Infertility. ANIMAL(S) Adult female db/db mice. INTERVENTION(S) Adult littermate wild-type (WT) and diabetic (db) leptin receptor (LR) mutant female mice were matched for the allograft of the(More)
The aim of the study is to investigate the molecular mechanism behind androgen reduction in porcine granulosa cells (pGCs) with Salvia miltiorrhiza Bunge extract cryptotanshinone. PGCs were isolated from porcine ovaries and identified. Androgen excess model of the pGCs was induced with the MAPK inhibitor PD98059 and then treated with cryptotanshinone. The(More)
This trial explores 1) prenatally androgenized (PNA) rats as a model of polycystic ovary syndrome (PCOS) and 2) reproductive and metabolic effects of cryptotanshinone in PNA ovaries. On days 16-18 of pregnancy, 10 rats were injected with testosterone propionate (PNA mothers) and 10 with sesame oil (control mothers). At age 3 mo, 12 female offspring from(More)
INTRODUCTION Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in reproductive-age women. Chinese herbal medicine has been used for the treatment of PCOS, but the evidence for its efficacy and safety is minimal. Tanshinones are a class of bioactive molecules isolated from Salvia miltiorrhiza, a commonly used herb in Traditional(More)
INTRODUCTION Letrozole is being used as an alternative to clomiphene citrate in women with polycystic ovary syndrome (PCOS) requiring ovulation induction. Berberine, a major active component of Chinese herbal medicine rhizoma coptidis, has been used to improve insulin resistance to facilitate ovulation induction in women with PCOS but there is no study(More)
BACKGROUND Insulin resistance and hyperinsulinemia play a key role in the pathogenesis of polycystic ovary syndrome (PCOS), which is characterized by hyperandrogenism, ovulatory dysfunction, and presence of polycystic ovaries on pelvic scanning. Insulin resistance is significantly associated with the long-term risks of metabolic syndrome and cardiovascular(More)
HBV X protein plays crucial roles during viral infection and hepatocellular carcinoma (HCC) development through interaction with various host factors. Here, we mapped the interactome of HBx using a yeast two-hybrid screen. Nine human proteins were identified as novel interacting partners of HBx, one of which is phospholipid scramblase 1 (PLSCR1). PLSCR1 is(More)
About 10-15% of couples have difficulty conceiving at some point in their reproductive lives and thus have to seek specialist fertility care. One of the most commonly used treatment options is in vitro fertilization (IVF) and its related expansions. Despite many recent technological advances, the average IVF live birth rate per single initiated cycle is(More)
Genital infection is a common worldwide disease among females with clinical features such as bilateral lower abdominal tenderness, abnormal vaginal or cervical discharge, fever, abnormal vaginal bleeding, dyspareunia, vaginal itching, and adnexal tenderness, which can significantly impair women's health and quality of life. Genital infection is commonly(More)
Exosomes are secreted small vesicles that mediate various biological processes, such as tumorigenesis and immune response. However, whether the inflammasome signaling leads to the change of constituent of exosomes and its roles in immune response remains to be determined. We isolated the exosomes from macrophages with treatment of mock, endotoxin, or(More)
