Combination therapy with HDAC6 inhibitor ACY-1215 and JQ1 synergistically suppresses SCLC growth in preclinical mouse models. Although our shRNA library covered all members of the HDAC family, only HDAC6 knockdown resulted in enhanced sensitivity to JQ1 (Supplementary Fig. S4A). Next, we performed a pilot treatment study in athymic nude mice

Isoform-selective HDAC inhibitors are emerging as potentially more targeted agents. ACY-1215 (ricolinostat) is a first-in-class selective HDAC6 inhibitor. To better understand the discrete function of HDAC6 and its role in lymphoma, we developed a lymphoma cell line resistant to ACY HDAC6 is the largest HDAC protein identified (1215aa) and the only HDAC having two different, independently active deacetylase domains. Initial characterization of this HDAC assigned its localization and function to the cytoplasmic compartment [46,104]. However, recent reports showed that HDAC6 is also present in the nucleus [105,106].

ACY-1215 (ricolinostat) is a first-in-class selective HDAC6 inhibitor. To better understand the discrete function of HDAC6 and its role in lymphoma, we developed a lymphoma cell line resistant to ACY HDAC6 is the largest HDAC protein identified (1215aa) and the only HDAC having two different, independently active deacetylase domains. Initial characterization of this HDAC assigned its localization and function to the cytoplasmic compartment [46,104]. However, recent reports showed that HDAC6 is also present in the nucleus [105,106]. Cortactin, the cytoplasmic substrate of HDAC6, is known to play an actin cytoskeletal regulatory role which is implicated in the motility of cancer cells, and thus in cancer progression. Its activity is found to be regulated by HDAC6.

Purpose: Pan-class histone deacetylase (HDAC) inhibitors are effective treatments for select lymphomas. Isoform-selective HDAC inhibitors are emerging as potentially more targeted agents. HDAC6 is a class IIb deacetylase that facilitates misfolded protein transport to the aggresome for degradation. We investigated the mechanism and therapeutic impact of the selective HDAC6 … Dec 13, 2016 Jan 23, 2019 Finally, HDAC6 overexpression is able to rescue the phenotype of a Drosophila model of spinobulbar muscular atrophy, indicating that HDAC6 might partially counteract the pathogenesis of neurodegenerative disorders characterized by an impaired UPS 36. All together, these data strongly suggest that HDAC6 is a master regulator of the protective Jul 25, 2020 Histone deacetylase 6 (HDAC6) is a unique Class IIb HDACs, in that it is a predominant cytoplasmic protein with two deacetylase domains, and it has been demonstrated to promote tumor growth in many human cancers including gastrointestinal cancers.

The co-treatment of PTX and the two HDAC6-selective inhibitors in ARID1A-null ovarian cancer cells synergistically increased apoptosis (Figs. 4 and 5) and decreased cell growth and viability . ARID1A deficient ovarian cancers fail to inhibit HDAC6 activity, which normally deacetylates α-tubulin that is crucial for the induction of microtubule

Histone deacetylase inhibitors (HDAC inhibitors, HDACi, HDIs) are chemical compounds that inhibit histone deacetylases.. HDIs have a long history of use in psychiatry and neurology as mood stabilizers and anti-epileptics. More recently they are being investigated as possible treatments for cancers, parasitic and inflammatory diseases.
