Confirmation of RNA and protein expression levels by real-time quantitative PCR and western blotting analysis (n = 3, per treatment type). (A) The expression of LASP1 and ferritin light and heavy chain mRNAs relative to that of GAPDH, the internal control, as detected by real-time PCR. (B) Expression of LASP1 and ferritin light and heavy chains, as assessed by western blotting analysis. The signal corresponding to the protein bands was quantified using densitometric scanning and the relative protein abundance was determined after normalization with the levels of β-actin protein. Data are presented as mean ± SD and compared using the t-test for independent samples. *p <0.05, indicating significant differences between the two samples compared.
