To leverage the tools, resources and knowledge that exist for C. elegans so that we can study ecology, evolution and other aspects of biology, we need to understand the natural history of this important model organism.
RNA binding protein FOX-1 functions as a dose-dependent X-signal element to communicate X-chromosome number and determine nematode sex by controlling alternative non-productive pre-mRNA splicing of the master sex-determination switch gene.
The functional interaction of Na+ and KATP channels at the intercalated disk of cardiomyocytes depends on Ankyrin G and is clinically relevant since KATP channel mutations affect Na+ channel expression.
A recent report proposing that the dpp stripe (the main source of the protein dpp) is dispensable for Drosophila wing disc growth missed the critical role on growth due to imprecise spatial removal of dpp.
Cytonemes mediate, and are essential for, Wingless signaling from the Drosophila wing disc to disc-associated myoblasts and for Delta-Notch signaling from these myoblasts to the dorsal air sac primordium.
