چکیده

Normal pregnancy is essential for human reproduction. However, BaP (benzo(a)pyrene) and its metabolite BPDE (benzo(a)pyrene-7,8-dihydrodiol-9,10-epoxide) could cause dysfunctions of trophoblast cells might further induce miscarriage. Yet, the underlying mechanisms remain largely unknown. Herein, we identified a novel upregulated lnc-HZ04 downregulated miR-hz04 in villous tissues unexplained recurrent miscarriage (RM) relative to those healthy control also BPDE-treated cells. Lnc-HZ04 directly specifically bound with miR-hz04, diminished reduction effects on IP3R1 mRNA expression level stability, then activated Ca2+-mediated IP3R1/p-CaMKII/SGCB pathway, which promoted cell apoptosis. The target site played crucial roles these regulations. In normal trophoblast, relatively less more suppressed this apoptosis pathway gave pregnancy. After exposure or RM tissues, p53 was upregulated, promote p53-mediated transcription. Relatively mice by upregulating corresponding murine pathway. Therefore, BPDE-induced associated occurrence This work discovered regulation provided scientific clinical understanding

Induction of apoptosis in human tumor cell lines by platelets

Introduction: It has been reported that platelets can eradicate tumor cells in vitro, although the mechanism of this effect has not been determined. The effect of platelets on the induction of apoptosis in tumor cells is largely unknown. Materials and methods: To investigate this effect, two human hematologic cell lines, K562 and Daudi, were independently faced with unstimulated and thromb...

Downregulation of HMGB1 by miR-103a-3p Promotes Cell Proliferation, Alleviates Apoptosis and Inflammation in a Cell Model of Osteoarthritis

Background: MiR-103a-3p is a small non-coding RNA and has been reported to be involved in osteogenic proliferation and differentiation, but the role of miR-103a-3p in human osteoarthritis (OA) remains unclear. Objectives: In this study, we aimed to explore its function and molecular target in chondrocytes during OA pathogenesis. Materials an...

Overexpression of FZD7 promotes glioma cell proliferation by upregulating TAZ

Gliomas are the most prevalent type of primary brain tumors in adults, accounting for more than 40% of neoplasm in the central nervous system. Frizzled-7 (FZD7) is a seven-pass trans-membrane Wnt receptor that plays a critical role in the development of various tumors. In this study, we detected high-level FZD7 expression in glioma and its overexpression was associated with advanced tumor stage...

Inactivation of the MAPK signaling pathway by Listeria monocytogenes infection promotes trophoblast giant cell death

Listeria monocytogenes has a well-characterized ability to cross the placental barrier, resulting in spontaneous abortion and fetal infections. However, the mechanisms resulting in infection-associated abortion are not fully understood. In this study, we demonstrate that the dephosphorylation of MAPK family proteins caused by L. monocytogenes infection of trophoblast giant (TG) cells, which are...
