Figure Lengend Snippet: IGF2BP3 directly interacts with SRD5A3 mRNA and increases its stability. A The m6A levels of SRD5A3 in T24R and 5637R cells, and their wild-type counterparts were tested by MeRIP-qPCR. B The m6A levels of SRD5A3 in T24R and 5637R cells following IGF2BP3 knockdown or overexpression. C IGF2BP3 RNP SRD5A3 mRNA enrichment in T24R and 5637R cells following IGF2BP3 knockdown or overexpression. D A schematic diagram presenting three methylation sites on SRD5A3 and mutates these sites ( A – C ). E The luciferase activities of the WT or Mut luciferase reporters in HEK-293 T cells following IGF2BP3 knockdown. F The mRNA stability of SRD5A3, SRD5A1, and SRD5A2 in T24R and 5637R cells following IGF2BP3 knockdown after actinomycin D treatment (normalized to 0 h). G The IGF2BP3 mRNA and protein expression levels were determined by qRT-PCR and immunoblotting analysis in parental cells and CDDP-resistant cells. H SRD5A3 mRNA and protein expression levels were determined by qRT-PCR and immunoblotting analysis in T24R and 5637R cells following IGF2BP3 knockdown or overexpression. Six independent experiments yielded results. The repeated-measures ANOVA plus Sidak’s multiple comparisons test was performed in panel ( F ) and unpaired t tests were performed in other panels. * P < 0.05
Article Snippet: The membranes were incubated with rabbit polyclonal anti-SRD5A3 antibody (PA5-55480, Invitrogen, Carlsbad, CA, USA), mouse monoclonal anti-IGF2BP3 antibody (MA5-27480, Invitrogen), and mouse monoclonal anti-GAPDH antibody (MA5-15738, Invitrogen), followed by rinse with TBST and incubation with secondary antibodies.
