Transcriptional regulation
- Rapid and parallel changes in activity and mRNA of intestinal peptidase to match altered dietary protein levels in juvenile house sparrows (Passer domesticus)
Summary: Phenotypic flexibility that is fast but not too fast: modulation of intestinal peptidase to match altered dietary protein level in nestling house sparrows involves parallel change in aminopeptidase-N activity and mRNA.
- microRNA-29b knocks down collagen type I production in cultured rainbow trout (Oncorhynchus mykiss) cardiac fibroblasts
Summary: Increased expression of microRNA-29b decreases collagen type I synthesis in rainbow trout (Oncorhynchus mykiss) cardiac fibroblasts, suggesting that this microRNA could play a role in temperature-induced changes in collagen content in the trout heart.
