It is well known that dynamic stress or mechanical stimulus plays a major role in cell regulation [ 31– 31].
Aside from its classical role in structure and support, the ECM has a major role in cell regulation, migration, proliferation, and survival.
Although they have been traditionally viewed as enzymes involved in terminal protein degradation, knockout (KO) mice have revealed major roles in cell regulation, i.e. of cell proliferation and adhesion, apoptosis, lipid metabolism and immune response 5, 6.
On the other hand, a down-regulation of the major cell wall constituents (β-1,3 glucanases BGL2 and EXG1, cell wall mannoproteins CCW12, CWP2 and TPI1, GPI-glycoproteins GAS1 and SED1, PST1) and genes coding for proteins required for the transport of cell wall components to the cell surface (SBE22) is manifest.
Acinar epithelial cells of the LG are the major cell type responsible for the production and regulation of fluid and protein on the ocular surface.
Decreased expression of these two transcripts suggests that B-SWCNT cells lost two major cell protection mechanisms including a major p53 pro-apoptotic signaling pathway and positive regulation of autophagy.
Draining lymph nodes from transplanted mice showed focal up-regulation of major developmental stem cell regulators, such as BMP-4, Noggin and Sonic hedgehog.
Although positive feedback and ultrasensitivity have been observed in various MAPK cascades (reviewed in [ 35]), in HEK293 cells the major feedback regulation is negative, confirming the predictions of the modeling.
Detailed and systematic network analysis revealed that these hub genes played roles as major regulators in cell-cycle regulation, kinase modulation, and the development of various tumors.
The tumor-suppressor protein p53 is a major player in regulation of cell growth, genomic stability, and cell death.
