TAp73 regulates ATP7A: possible implications for ageing-related diseases

Figure 2. TAp73 regulates ATP7A expression level. (a) ATP7A mRNA levels were analysed by quantitative PCR after TAp73 silencing (siRNA-1/2 p73). Relative mRNA expression was normalized against TBP and calculated as fold change to the control treatment (Scr). Data is reported as mean ± s.d. of three experiments. ** p < 0.001, * p < 0.05 (Student's T-test). (b) p73 and p21 mRNA levels were analysed by quantitative PCR after TAp73 overexpression (HA-TAp73 α-β) and p73 silencing (siRNA-1/2 p73). Up- and downregulation of p21, a TAp73 transcriptional target, confirmed p73 transcriptional activity modulation. Relative expression of genes was normalized against TBP and calculated as fold change to the control treatments (EV and Scr). Data is reported as mean ± s.d. of two experiments. * p < 0.05 (Student's T-test). (c-e) Protein levels of ATP7A, HA-TAp73 or endogenous TAp73 and GAPDH were analysed by WB in cell overexpressing or depleted for TAp73. Figure shows a representative replicate of three independent experiments.
