Figure Lengend Snippet: MiR-29a regulation of target gene expression in cochlea from miR-29a +/+ and miR-29a –/– mice. (A–G) With β-actin as a control, COL4A1, COL4A2, COL4A3, COL4A4, COL4A5, LAMB2, and LAMC1 protein levels in cochlea were analyzed by Western blot. The independent t -test was used to compare data between two groups [COL4A1, t (4) = 9.920, P < 0.001; COL4A2, t (4) = 3.847, P = 0.018; COL4A3, t (4) = 3.389, P = 0.028; COL4A4, t (4) = 2.842, P = 0.047; COL4A5, t (4) = 3.782, P = 0.019; LAMB2, t (4) = 3.915, P = 0.017; LAMC1, t (4) = 3.088, P = 0.037]. (H) The mRNA expression levels of target genes as measured by qRT-PCR [independent t -test, Col4a1, t (4) = 6.050, P = 0.004; Col4a2, t (4) = 13.145, P < 0.001; Col4a3, t (4) = 3.735, P = 0.02; Col4a4, t (4) = 7.238, P = 0.002; Col4a5, t (4) = 13.141, P < 0.001; Lamb2, t (4) = 8.529, P = 0.001; Lamc1, t (4) = 3.126, P = 0.035]. All data are shown as the mean ± SD, n = 3 biological replicates, * P < 0.05, ** P < 0.01, and *** P < 0.001 between two groups.
