If deficits in neurosensory function are an expression of exposure to the toxicant(s) in question, the resulting overcontrol may lead to a false negative finding or type II error.
Vorinostat suppressed cyclin D1 expression irrespective of exposure to B[a]P in A549 cells.
The goal of these studies is to identify the patterns of alteration of gene expression characteristic of exposure to each class of toxicant in cultured human cells.
Prevalence of dental fluorosis in early age (15 20 years) is an expression of higher exposure to fluoride, and it is fairly important since it affects permanent teeth leading to mild, moderate, or severe level of dental fluorosis.
Many microRNAs undergo altered expression as consequence of exposure to carcinogens and these changes may be useful in cancer prevention [ 4].
This suggests that, in these individuals, exposure to HIV can trigger APOBEC3G expression in the absence of infection and that the expression decreases with cessation of exposure [ 159].
Cells suspended in collagen gels were exposed to interstitial flow (1 cmH2O, ∼0.05 dyn/cm2, 3-D), and after 6 h of exposure, expression of SM-MHC, smoothelin, and calponin were significantly reduced, while expression of α-SMA and SM22 were markedly enhanced.
These genes have a gradual decrease in expression until 6 hours of exposure to cold, at which point they reached their lowest level of expression.
In the present investigation, the effect of ZnO-NPs on alteration of gene expression after exposure of ZnO-NPs was analysed in two genes, namely, mtl-1 and sod-1 by using stress response gene expression profiling analysis [9].
There was a significant (P<0.05) difference in the HSP mRNA expression at different levels of exposure.
