Histone deacetylase Inhibitor

Trichostatin A (TSA), an antifungal antibiotic produced by Streptomyces hygroscopicus [1], is a potent and specific inhibitor of histone deacetylases (HDACs), which are overexpressed in various cancers and closely correlate with oncogenic factors.

Trichostatin A is active at nanomolar concentrations in mammalian cells. By suppressing the activity of HDACs, it leads to increased histone acetylation, thereby causing highly acetylated histones to accumulate in the cell [2]. This in turn induces enhanced expression of specific genes that elicit extensive cellular morphologic and metabolic changes such as growth arrest, differentiation and apoptosis. At submicromolar concentrations Trichostatin A has been shown to induce apoptosis in diverse cancer cells while exhibiting very low toxicity to normal cells.

Interestingly, HDACs epigenetically silence transcription of the autophagy-related genes Atg and LC3. Thus, HDAC inhibitors like Trichostatin A and SAHA can lead to augmented levels of Atg and LC3 proteins and consequently, promote autophagy.
