Previous cDNA microarrays indicated that CLDN1 (claudin-1) is an important gene for ovarian cancer-initiating cell (OCIC) invasion and adhesion. Here, we show that the downregulation of miR-155 in OCICs correlates with CLDN1 overexpression and the suppression of OCIC invasion. Luciferase assays indicate that miR-155 targets CLDN1 mRNA on the 3' UTR. CLDN1(More)
The incidence of premature ovarian failure (POF), also known as ovarian insufficiency, has been increasing in recent years. Although some treatments are currently available, improved treatment strategies are urgently required. Many researchers have reported that human endometrial stem cells (HuMenSCs), which exhibit stem/progenitor cell properties in vitro(More)
Protein arginine methylation, which is mediated by the protein arginine methyltransferases (PRMTs), is associated with numerous fundamental cellular processes. Our previous studies have shown that PRMT1 activated Hedgehog signaling in the esophageal squamous cell carcinoma (ESCC) cells and promoted the growth and migration of cancer cells. However, the(More)
The mechanism underlying the development of human ovarian cancer is poorly understood. The liver kinase protein, LKB1, is hypothesized to play a pivotal role in tumor cell proliferation and invasion capacity through regulation of p53 and p21/WAF1 expression. Previous studies suggest LKB1 may, in turn, be regulated by microRNA-17. Here, we examined the role(More)
The incidence of premature ovarian failure (POF), a condition causing amenorrhea and hypergonadotropic hypoestrogenism in women before the age of 40, has been increasing in recent years. As an irreversible pathological change, improved treatment strategies for this disease are urgently needed. In this study, a type of microRNA (miR-17-3p) was used to guide(More)
Ophiobolin O is a member of ophiobolin family, which has been proved to be a potent anti-tumor drug candidate for human breast cancer. However, the anti-tumor effect and the mechanism of ophiobolin O remain unclear. In this study, we further verified ophiobolin O-induced G1 phase arrest in human breast cancer MCF-7 cells, and found that ophiobolin O reduced(More)
A specific and reliable liquid chromatography-electrospray ionization-tandem mass spectrometry method was developed for the simultaneous determination of timosaponin H1 (TH1), timosaponin E1 (TE1), timosaponin E (TE), timosaponin B-II (TB-II), timosaponin B-III (TB-III) and anemarrhenasaponin I (AS-I) in rat plasma. After addition of internal standard (IS)(More)
The cluster of microRNAs (miRNAs) in the DLK1-DIO3 genomic imprinted region contains several miRNAs that have a significant regulatory role in tumor proliferation and invasion. One of these miRNAs is miR-134-3p, and its expression changes significantly in human ovarian cancer stem cells (OCSCs) and in CD44-/CD133- ovarian cancer. The results of a luciferase(More)
