Rac and Cdc42 inhibitors reduce macrophage function in breast cancer preclinical models

21 views | Dec 16 2023

Rac and Cdc42 inhibitors EHop-016 and MBQ-167 demonstrate dual efficacy by simultaneously targeting metastatic cancer cells and immunosuppressive myeloid cells in the tumor microenvironment, creating an anti-tumor environment in breast cancer. [Read the Full Post]

ARHGEF37 overexpression promotes extravasation and metastasis of hepatocellular carcinoma via directly activating Cdc42

14 views | Dec 03 2023

The study reveals that ARHGEF37 upregulation in hepatocellular carcinoma promotes pulmonary metastasis by enhancing tumor cell adhesion to endothelial cells and trans-endothelial migration via direct activation of Cdc42, and targeted inhibition of this pathway using ZCL278 presents a potential therapeutic approach for preventing and treating HCC lung metastasis.
