SCEE may give cell protection by hindering CCl4-mediated lipid peroxidation, hence blocking the generation of free radical derivatives [ 49].
In addition to these biological roles, the mutually exclusive interaction between genes that program cell death (mcrBC) and an invading methyltransferase gene may give host cells an advantage in defence against viral infection when the virus carries a methyltransferase gene.
Thus, to some extent, aerobic glycolysis may give cancer cells an advantage in competing with normal tissues for nutrients.
An increased reliance on glycolysis for production of ATP may give surviving cells an advantage in the hostile environment of the AD brain.
This prolonged incubation may give the cells more time to adapt to inhibition of oxidative phosphorylation, perhaps by upregulating glycolysis.
Our in vivo experiments showed that, for the Gis1 transcription factor at least, proteasome-mediated control is crucial for a rapid return to growth after nutrient starvation, which may give yeast cells an important selective advantage over their competitors.
While PTEN expression therefore seems to be regulated in part by TGF-β1 (Li et al, 1997a), we raised the hypothesis that the overexpression of TGF-β1 in pancreatic cancers may reduce the expression of PTEN which in turn may give these cells an additional growth advantage.
Thus, despite the fact that PTEN inactivation through PTEN mutation or deletion is infrequent in pancreatic cancer, we raise the hypothesis that TGF-β1 overexpression may lead to reduced PTEN mRNA levels in pancreatic cancers which may give these cells an additional growth advantage and, thus, contributes to the aggressive phenotype of this cancer.
The results of our analyses of MCF-7 breast cancer cells engineered to express the receptor provide evidence that PTHRP-R overexpression may be sufficient to give cells a selective advantage in terms of their proliferative capacity.
Studies show that OTX2 may give stem cell-like properties to tumor cells via epigenetic regulation and transcriptional repression of differentiation markers [89, 90].
