WebMar 30, 2024 · These results suggest that both Crk and Grb2 may contribute to the activation of Erk by oncogenic Abl, whereas Nck is unlikely to participate in this pathway. Next we examined whether combinations of these dominant-negative adapters could inhibit Erk activation more effectively than each mutant alone. WebNov 5, 2024 · Glucose is transported into β-cells via GLUT2 in an insulin-independent way with concentration gradient. Then, glucose is phosphorylated by glucokinase to glucose-6-phosphate, which allows for its inclusion to metabolic processes and ATP production. Raised ATP level triggers accumulation of K + ions along with membrane depolarization. lamart palais royal
