HDAC6 deacetylate substrates such as α-tubulin and cortactin, resulting in degradation of structural proteins and functional loss. In addition, during stress, HDAC3, 27 HDAC4, 26 and HDAC6 28 colocalize with sarcomeric proteins and contribute to hypocontractility by deacetylation of sarcomeric and cytoskeletal proteins. HDAC6 inhibition represents a novel strategy to improve the efficacy of anti-CD20 mAbs. HDAC6 inhibition increases CD20 levels by enhancing CD20 protein synthesis without affecting the gene expression.

Apr 12, 2018 · HDAC6 silencing by specific shRNA was followed by reduced Notch3 expression and increased apoptosis of T-ALL cells.

Sep 03, 2018 · Histone deacetylase 6 (HDAC6) is a unique member of the HDAC family that not only participates in histone acetylation and deacetylation but also targets several nonhistone substrates, such as α-tubulin, cortactin, and heat shock protein 90 (HSP90), to regulate cell proliferation, metastasis, invasion, and mitosis in tumors. Mar 28, 2012 · HDAC6, a cytoplasmic class IIb isoform, is a prime candidate to mediate histone-independent effects of pan-HDAC inhibitors (Verdel et al., 2000; Hubbert et al., 2002). Jan 29, 2019 · Only the use of high concentrations of selective HDAC6 inhibitors resulted in co‐inhibition of other HDAC enzymes and consequently in reduced growth, migratory and/or invasive activity of cancer cells in vitro as well as in vivo. The specificity of HDAC6 inhibition was confirmed using a CRISPR/Cas9 knockout cell line. Jan 29, 2013 · The role of HDAC6 as a tubuline deacetylase was investigated within the cascades of various NDs. It is now clear that HDAC6 plays a central role in protein aggregate elimination, in neuronal oxidative stress and in the mitochondrial transport. The implication of HDAC6 in these three particular processes is discussed below. HDAC6 inhibition both in vitro and in vivo enhances HMGN2 acetylation with a concomitant reduction in Stat5a-mediated signaling, resulting in an inhibition of breast cancer growth.
