Abstract Background Human microRNAs (miRNAs) have diverse functions in biology. and play a role in nearly every biological process. Here we report that miR-520d-5p (520d-5p) causes undifferentiated cancer cells to adopt benign or normal status in vivo in immunodeficient mice via demethylation and P53 upregulation. Further we found that 520-5p causes normal cells to elongate cellular l... https://jalyttlers.shop/product-category/chillys-cup/
