Example: "As the conversation progressed, you could see her begin to alter her expression, reflecting her growing concern."
Alternatives: "change their demeanor" or "modify their facial expression".
We report here that in neurons and astrocytes, miRNAs alter their expression levels in response to OGD in vitro and that these alterations are cell-specific.
Therefore, the purpose of this study was to determine if osteoblasts that attach to MTA surfaces alter their expression of inflammatory cytokines.
Most hepatoma cell lines as well as PHH in 2D either alter their expression of key innate immune receptors or loose expression rapidly following plating on collagen-coated plates, hindering the evaluation of physiological host responses.
In conclusion, neurons of rat trigeminal ganglia alter their expression of neuropeptides during cell and organ culture differently, but it is mainly the CGRP system that is up-regulated.
Although factors involved in altered HO-1 expression in these cells remain unknown, the results suggest that Kupffer cells could alter their expression of HO-1 in response to local hemodynamic changes associated with chronic portal hypertension in humans.
The present study was designed to investigate ADAMTS-1, -4 and -5 and TIMP-3 expression after experimental cerebral ischaemia and to examine whether cytokines known to be up-regulated in stroke could alter their expression by astrocytes in vitro.
Unlike this woman, many Botox users receive extensive injections above the nose, around the eyes and across the forehead, which deeply alter their expressions.
Now, it turns out, horses also use the muscles underlying their facial features eyes, nostrils, and lips to alter their expressions, scientists report today in PLOS ONE.
Dependencies between the fates of linearly filiated cells and/or cross-sectional dependencies (either between fates or lifespans), however, will not alter their expressions.
Most of the aberrantly expressed proteins are acute phase proteins, which altered their expression level in response to the inflammation associated with the development of cancer [ 20].
