- Navigating the Signaling Network: RTK and GPCR Crosstalk Uncovered
One fascinating aspect of the cellular signaling network is the crosstalk between G protein-coupled receptors On the other hand, RTKs play pivotal roles in growth factor signaling, regulating cell growth, differentiation phospho-mimicking mutants and assays such as linear ion trap mass spectrometry, BRET, pull down, and transwell cell These findings have broad implications for understanding cellular signaling in both normal physiology behaviors in cancer, promoting uncontrolled cell migration and invasion.

activating properties of human salivary histatin 1 "Human salivary histatin 1 (Hst1) exhibits a series of cell-activating properties, such as promoting cell spreading, migration, and metabolic activity. We also adopted live cell imaging to monitor the whole intracellular trafficking process of F-Hst1. Our results showed that the inhibition of cellular respiration hindered the internalization of F-Hst1 reduced the uptake, which was accompanied by the nullification of the promoting effect of F-Hst1 on cell
