Representative ICC images and quantification for cTnT+ pH3+ ( j ) and cTnT+ Ki67+ ( k ) NMCMs treated with LncBAR along with small molecule LY294002 (PI3K/AKT pathway inhibitor). Cells infected with lentiviral LacZ and treated with DMSO were used as control. White arrows indicate proliferating NMCMs ( n = 15 fields). Scale bars, 100 µm. l RT-qPCR analysis showing expression of genes involved in positive regulation of cell cycle in LncBAR overexpressed NMCMs treated with or without LY294002 inhibitor ( n = 3 biological replicates). Data are presented as mean ± SEM. Statistical significance was determined by two-tailed unpaired t test or two-way ANOVA with Tukey’s multiple comparisons test. * P < 0.05, ** P < 0.01, *** P < 0.001.
