The Role of PinX1 in Growth Control of Breast Cancer Cells and Its Potential Molecular Mechanism by mRNA and lncRNA Expression Profiles Screening

Figure 1

qRT-PCR and western blotting analysis of PinX1 expression in PinX1 overexpressed and knocked-down breast cell lines. (a) Fold changes ( values) by qRT-PCR showed increased expression of PinX1 mRNA in the pcDNA3.1-PinX1 transfected breast cancer cell lines MCF-7, MDA-MB-231, and SK-BR-3 when compared with their counterpart untransfected cells and empty vector transfected control cells. Expression levels were normalized for GAPDH. (b) Western blotting indicated upregulation of PinX1 protein in the pcDNA3.1-PinX1 transfected breast cancer cell lines MCF-7, MDA-MB-231, and SK-BR-3 in comparison with untransfected cells and empty vector transfected control cells. (c) Fold changes ( values) by qRT-PCR showed decreased expression of PinX1 mRNA in the PinX1 siRNA fragments transfected MCF-10A cells, when compared with the untransfected cells and siRNA NC transfected control cells. (d) Western blotting indicated downregulation of PinX1 protein in the PinX1 siRNA fragments transfected MCF-10A cells in comparison with untransfected cells and siRNA NC transfected control cells.
