background: some recent studies reported human epidermal growth factor receptor (her-2/neu) as a marker that can be used in immunological studies of colorectal carcinoma for predicting the prognosis and the treatment. therefore, we aimed to investigate the frequency of her-2 expression in patients with colorectal cancer, and explore the relationship between clinicopathological prognostic factor...
Pyruvate kinase type M2, which is expressed in multiple tumor cell types and plays a key role in aerobic glycolysis, also has nonglycolytic functions and can regulate transcription and cell proliferation. The results of this study show that epidermal growth factor receptor activation induces pyruvate kinase type M2 nuclear translocation. To further determine the relationship between pyruvate ki...
One of the fastest cellular responses following activation of epidermal growth factor receptor is an increase in intracellular Ca2+ concentration. This event is attributed to a transient Ca2+ release from internal stores and Ca2+ entry from extracellular compartment. Store-operated Ca2+ channels are defined the channels activated in response to store depletion. In the present study, we determin...
While all 2-methylene-19-nor analogs of 1α,25-dihydroxyvitamin D3 (1α,25(OH)2D3) tested produce an increase in epidermal thickness in the rhino mouse, only a subset reduce utricle size (comedolysis). All-trans retinoic acid (atRA) also causes epidermal thickening and a reduction in utricle size in the rhino mouse. We now report that 2-methylene-19-nor-(20S)-1α-hydroxybishomopregnacalciferol (2M...
Addition of epidermal growth factor to A431 cells results in dramatic changes in cell morphology. Initially the cells form membrane ruffles accompanied by increased actin polymerization, followed by cell rounding. Activation of the tyrosine kinase of the receptor by binding epidermal growth factor leads also to phosphorylation and activation of phospholipase C-gamma 1, a key enzyme in the phosp...
