Nettet11. jun. 2024 · Analysis of integrin-mediating signal pathways that control cell behavior revealed a significant increase in activity of Akt protein kinase in response to depletion of α2β1. The increase in Akt activity that accompanies a suppressive effect on cell invasion contradicts well-known Akt function aimed at stimulation of tumor progression. Nettet19. mar. 2014 · On the whole, integrins, mainly those containing the β1 subunit, being expressed both in PC cells and in PSCs, and regulating the production of ECM proteins by the latter, are pivotal in regulating tumour–stroma interaction in PC. β1 integrins can hence drive different aspects of tumour cell behaviour, including chemo- and radio … protear headphones instructionsNettetIntegrins are involved in many pathologies; here we focus on their roles in cancer.
