Explain why steroid use affects fertility in relation to the negative feedback loop. Define limiting factor and give an example. Define population density and explain how some limiting factors can become more important as a population's density increases. ...
This suggests that differential regulation of secreted glycoproteins and integrins direct actin cytoskeleton dynamics through focal adhesion complexes to generate a YAP positive feedback loop during collective invasion. The absence of distinct migratory or invasion signatures in single cell invasion using ...
IL-6 dramatically induced the expression of TWIST1 and SNAIL1 via STAT3 activation, leading to the initiation of an EMT. TWIST1, in turn, stimulated production of soluble IL-6, thereby generating a positive feedback loop that maintained the mesenchymal...
with a max of 20 percent going to public transit, sidewalks, and bike lanes. This leads to a negative feedback loop, where low investment in accessible, clean, and timely buses means people don’t take them, leading city planners to invest in them even less, says...
(AS) oligonucleotide RNAs complementary to overlapping regions of the distal stem-loop and bulge regions surrounding the inactivating GU mutation of the SPEAR element (Fig.7b, top-left). The beads were incubated with lysates of IFN-γ-treated U937 cells as EPRS1 source, and pulldowns subjected...
As miR-101 targets EZH2, its repression establishes a feed-forward loop, which results in the stable upregulation of EZH2 and the stable downregulation of miR-101.11,12 To address the potential contribution of these pathways to the biology of FGF-2-expressing bladder carcinomas, we searched ...
