... However, phosphorylation of apical myosin II regulatory light chain (MLC2; MYL9), which is coupled to activation of actomyosin, is blocked in Cfl1 mutants, indicating that cofilin 1 is required for the apical activation of actomyosin that is necessary for neural tube closure. By contrast, activated ...

This review explores the potential for changes in dietary macronutrients to differentially influence mitochondrial bioenergetics and thereby the frequency of mtDNA haplotypes in natural populations. Such dietary modification may be seasonal or result from biogeographic or demographic shifts. Mechani ...

Signal transduction



Signal transduction occurs when an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell. In turn, this receptor triggers a biochemical chain of events inside the cell, creating a response. Depending on the cell, the response alters the cell's metabolism, shape, gene expression, or ability to divide. The signal can be amplified at any step. Thus, one signaling molecule can cause many responses.
