A431 cells were established from an epidermoid carcinoma in the skin of an 85- year-old female patient. Epidermal growth factor (EGF) stimulation of A431 cells induces rapid tyrosine phosphorylation of intracellular signaling proteins which control cellular processes such as growth, proliferation and apoptosis.
The high ROS concentrations within cancer cells provide an environment for potential constitutive inactivation of PTP1B and it has been shown in two human cancer cell lines HepG2 and A431, that up to 40% of the Cys215 residues in PTP1B can be selectively irreversibly oxidized under these cellular conditions resulting in non-functional PTP1B.

Several widely used cell lines express this protein, these include A431, HeLa, HUT78, HEK-293, Jurkat, THP, PC12, RAJI, U937 and Meg-01. [4] SGEF was identified to contribute to the formation of atherosclerosis through promoting endothelial docking structures that resulted in retention of leukocytes at athero-prone sites of inflammation.

A single child displaying multi-organ epithelial inflammation was found to have a homozygous loss of function mutation in the EGFR gene. The pathogenicity of the EGFR mutation was supported by in vitro experiments and functional analysis of a skin biopsy. His severe phenotype reflects many previous research findings into EGFR function.
The researchers then investigated the treatment’s effects on cells affected by Alzheimer’s disease. They found that when xenon penetrated the blood-brain barrier, it altered the behavior of ...

The Troubled-Teen Industry Has Been A Disaster For Decades. It's Still Not Fixed.
WIPI2 mRNA is readily detectable in several commonly used laboratory cell lines (HEK293A, HeLa, A431) and several cancer cell lines, while WIPI1 expression is limited to cancer cells [citation needed] (but is also detected in many human tissues).
