JMJD2C promoted MALAT1 expression by regulating the histone methylation level of MALAT1 promoter. a Schematic diagram of the ChIP (Chromatin Immunoprecipitation) procedure for detecting the effect of JMJD2C on the histone methylation level of MALAT1 promoter in sites of H3K9m3 and H3K36m3. Purple ovals: no-targeting protein; Yellow ovals: targeting protein A; Green ovals: protein binding to targeting protein A. b JMJD2C, H3K9, H3K36 antibody and MALAT1 special primers were used to investigate the interaction between JMJD2C and MALAT1 promoter, IgG was used as the negative control. c-d MALAT1 promoter activities assay in HCT116 or LoVo cells transiently transfected with shRNA/NT vector, shRNA/JMJD2C vector, empty overexpression vector, or JMJD2C overexpression vector. e-f Real time PCR assay of MALAT1 levels in HCT116 or LoVo cells transiently transfected with shRNA/NT vector, shRNA/JMJD2C vector, empty overexpression vector, or JMJD2C overexpression vector. *, P < 0.05; **, P < 0.01 (t test)
