RAS Oncoproteins Scientific Review

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.

Cell Cycle & DNA Damage Repair

Cell Cycle & DNA Damage Repair Poster

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.

Epigenetics in Cancer

Epigenetics in Cancer Poster

Adapted from the 2015 Cancer Product Guide Edition 3, 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.
