KLC2 belongs to the target genes of the LINC00152-driven ceRNA network. (A) KLC2, STK39 and PHF19 are significantly downregulated in HuH7ΔLINC00152 compared to HuH7 control cells. (B) Western blot analysis confirmed the decrease in KLC2 expression in HuH7ΔLINC00152 (C,D). Reduced KLC2 mRNA and protein levels were observed following LINC00152 siRNA-medicated knockdown in HuH7 and HepG2 cells (E,F). Increased KLC2 mRNA and protein levels following overexpression of LINC00152 in HLE cells. Data are presented as mean ± SD of 4 independent experiments. Welch’s t-test was used: * p < 0.05, ** p < 0.01, *** p < 0.001. Abbreviations: gGFP, guide RNA targeting GFP; gLINC, guide RNA targeting LINC00152; siNS, scrambled, nonsense siRNA; siLINC_2/_3, siRNA 2 and 3 specifically targeting LINC00152; C, control cells transfected with empty vector; LINC00152 OE, LINC00152 overexpression; OE, overexpression; rel., relative.
