Biological Activity for Tubacin

Tubacin is a selective inhibitor of HDAC6; inhibits the second deacetylase domain (DD2). Does not inhibit HDAC6 histone deacetylase activity; reversibly inhibits α-tubulin deacetylation. Increases α-tubulin acetylation levels with no effect on histone acetylation or cell cycle progression.

Epigenetics Scientific Review

Epigenetics Scientific Review

Written by Susanne Müller-Knapp and Peter J. Brown, this review gives an overview of the development of chemical probes for epigenetic targets, as well as the impact of these tool compounds being made available to the scientific community. In addition, their biological effects are also discussed. Epigenetic compounds available from Tocris are listed.

Cell Cycle & DNA Damage Repair Poster

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. 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 Poster

Epigenetics in Cancer Poster

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.

Rheumatoid Arthritis Poster

Rheumatoid Arthritis Poster

Rheumatoid arthritis (RA) is a chronic destructive inflammatory autoimmune disease that results from a breakdown in immune tolerance, for reasons that are as yet unknown. This poster summarizes the pathology of RA and the inflammatory processes involved, as well as describing some of the epigenetic modifications associated with the disease and the potential for targeting these changes in the discovery of new treatments.
