How to use

In Vitro:

In cells Rhosin specifically inhibits RhoA activity and RhoA-mediated cellular function without affecting Cdc42 or Rac1 signaling activities. By suppressing RhoA or RhoC activity Rhosin can inhibit mammary sphere formation by breast cancer cells, suppress invasion of mammary epithelial cells, and induce neurite outgrowth of PC12 cells in synergy with NGF.

In Vivo:

Treatment with rhosin abrogates the lung metastasis of B16BL6 and 4T1 cells in vivo.
