Genetics, Genomics, and Evolutionary Biology
Aging is an inevitable process in most multicellular organism that is regulated by both genetic and environmental factors. Multiple pathways have been discovered using the nematode species Caenorhabditis elegans which were then shown to be conserved in other higher eukaryotes.…

A recent paper by Nelson and Ambros [1] reports that let-7 heterochronic microRNA is absent in Caenorhabditis species of the japonica group. Research in C. elegans has shown that let-7 plays an essential role during larval to adult transition and mutations…
