Regulation of embryonic growth and lysosomal targeting by the imprinted Igf2/Mpr gene.

abstract：:The nematode Caenorhabditis elegans is an important model for studying the genetics of ageing, with over 50 life-extension mutations known so far. However, little is known about the pathobiology of ageing in this species, limiting attempts to connect genotype with senescent phenotype. Using ultrastructural analysis an...
