Salirasib is an inhibitor of active Ras proteins. Displaces active Ras from the plasma membrane; impairs downstream signaling and inhibits proliferation of endometrial carcinoma cells. Also facilitates Ras degradation. Shown to induce autophagy in several human cancer cell lines.

Human osteosarcoma cells were incubated with 20 μM Salirasib for 30 min prior to treatment with 10 μM LPA to estimate COX-2 expression using Western blot analysis. Salirasib abolished LPA-induced COX-2 expression.

Written by Kirsten L. Bryant, Adrienne D. Cox and Channing J. Der, this review provides a comprehensive overview of RAS protein function and RAS mutations in cancer. Key signaling pathways are highlighted and therapeutic vulnerabilities are explored. This review also includes a detailed section on RAS drug discovery and targeting synthetic lethal interactors of mutant RAS. Compounds available from Tocris are listed.
In normal cells, each stage of the cell cycle is tightly regulated, however in cancer cells many genes and proteins that are involved in the regulation of the cell cycle are mutated or over expressed. Adapted from the 2015 Cancer Product Guide, Edition 3, this poster summarizes the stages of the cell cycle and DNA repair. It also highlights strategies for enhancing replicative stress in cancer cells to force mitotic catastrophe and cell death.
This poster summarizes the main epigenetic targets in cancer. The dysregulation of epigenetic modifications has been shown to result in oncogenesis and cancer progression. Unlike genetic mutations, epigenetic alterations are considered to be reversible and thus make promising therapeutic targets.
