Fig. 5From: The RNA demethylase ALKBH5 promotes the progression and angiogenesis of lung cancer by regulating the stability of the LncRNA PVT1Knockdown of ALKBH5 decreases the stability of PVT1 but not VEGFA mRNA in lung cancer cells. A m6A modification sites of VEGFA mRNA were predicted by SRAMP. B The stability of VEGFA over time in A549 cells transfected with si-ALKBH5 was measured by qRT‒PCR relative to time point 0. C qRT‒PCR was used to detect the expression of PVT1 in A549 and H1975 cells after silencing ALKBH5. D Kaplan‒Meier analysis was used to analyze the correlation between PVT1 expression levels and overall survival of patients with lung cancer from the TCGA database. E m6A modification sites of PVT1 were predicted by SRAMP. F RIP experiments were performed in A549 cells and the coprecipitated RNA was subjected to qRT-PCR for PVT1. Expression levels of PVT1 are as fold enrichment in ALKBH5 antibody relative to IgG immunoprecipitates. G The stability of PVT1 over time in A549 cells transfected with si-ALKBH5 or pcDNA3.1-ALKBH5 was measured by qRT‒PCR relative to time point 0. *: P < 0.05, **: P < 0.01, ***: P < 0.001Back to article page
