Background Mycoplasma genitalium , a prokaryotic microorganism, is known pathogen of sexually transmitted infections. Previously, we identified cyclophilin A (CypA) as the membrane receptor on human urethral epithelial cells (SV-HUC-1) that binds to M. protein adhesion (MgPa) and demonstrated recombinant MgPa (rMgPa) inhibits apoptosis via CypA-mediated regulation PI3K/AKT/NF-κB pathway. Given established interplay between autophagy apoptosis, this study aims investigate whether rMgPa in SV-HUC-1 by modulating CypA/PI3K/AKT/mTOR-dependent autophagy. Methods In work, after were stimulated with rMgPa, was detected using Western blotting, immunofluorescence transmission electron microscopy, respectively. blotting Annexin V/PI assays used determine signaling pathway involved rMgPa- inhibited inducing Results upregulated autophagy-related proteins ATG7 LC3B while downregulating P62 expression cells.

Furthermore, found regulate PI3K/AKT/mTOR CypA, thereby promoting blot analysis urothelial through CypA-dependent mechanism.

Glioblastoma stem cells (GSCs) play a pivotal role in the initiation, progression, resistance to treatment, and relapse of glioblastoma multiforme (GBM). Thus, identifying potential therapeutic targets drugs that interfere with growth GSCs may contribute improved treatment outcomes for GBM. In this study, we first demonstrated functional protein arginine methyltransferase 1 (PRMT1) GSC growth. Furamidine, PRMT1 inhibitor, effectively inhibited proliferation tumorsphere formation U87MG-derived by inducing cell cycle arrest at G0/G1 phase promoting intrinsic apoptotic pathway.
