摘      要:An important factor in the emergence and progre sion of osteosarcoma(OS)is the dysregulated expression of microRNAs(miRNAs).Transcription factor 7-like 1(TCF7LI),a member of the T cell factor/lymphoid enhancer factor(TCF/LEF)transcription factor family,interacts with the Wnt signaling pathway regulator β-catenin and acts as a DNA-specific binding *** study sought to elucidate the impact of the interaction between miR 3293p and TCF7L1 *** growth and apoptosis of OS and analyze the regulatory expression relationship between miRNA and mRNA in osteosarcoma cells using a variety of ***329-3p was significantly downregulated,while TCF7L1 was considerably up-regulated in all examined OS cell ***,a clinical comparison study was performed using the TCGA ***,the regulatory relationship between miR-329-3p and TCF7L1 on the proliferation and apoptosis of OS cells was verified through in vitro and in vivo *** miR 329-3p was transfected into the OS cell line,the expression of TCF7L1 decreased,the proliferation of OS cells was inhibited,the cytoskeleton disintegrated,and the nucleus condensed to fom apoptotic *** expression of proteins that indicate apoptosis increased *** cell cycle was arrested in the G0/G1 phase,and the G1/S transition was *** introduction of miR 3293p also inhibited downstream Cyclin D1 of the Wnt *** experiments indicated that the overexpression of miR-329-3p signi ficanly inhibited the growth of OS xenografts in nude mice,and the expression of TCF7L1 and C-Myc in tumor tssues *** 329-3p was significantly reduced in OS cells and played a suppressive role in tumorigenesis and proliferation by targeting TCF7L1 both in vitro and in *** cell cycle arrest and pathway inhibition were observed upon the regulation of TCF7LI by miR *** these results,it can be inferred that miR.3293p exerts anticancer efects in osteosarcom
