Figure 3From: Expression of miR-1, miR-133a, miR-133b and miR-206 increases during development of human skeletal muscleAlterations in miRNA targets and inducer in muscle cells during development. Western blot analysis showed increased levels of HDAC4 (A), a verified target of miR-1, and Connexin 43 (B), a verified target of miR-206 and miR-1 in foetal muscle cells, compared to newborn cells. Western blot analysis of MyoD (C), an inducer of all four miRNAs, showed decreased levels in foetal muscle cells compared to newborn cells.Back to article page
