The following biological data are also contained in this article: 1) the cellularization of skeletal muscle myotubes by LDD-1819 or two small molecule inhibitors of glycogen synthase kinase-3β and aurora kinase A (BIO and reversine) and gene expression data for the myoblast markers Pax-7 and Myf5, 2) Cell viability of hTERT human immortalized fibroblasts, colon cancer cells and breast cancer cells, and 3) Western blotting analysis of full length and cleaved caspse-7, and cleaved poly (ADP-ribose) polymerase (PARP) in hTERT fibroblasts treated with LDD-1819. This evidence concerns the gene MYF5 and breast carcinoma.
