This is the first report that L(3)mbt-like 2 (L3MBTL2) specifically interacts with the histone deacetylase domain of histone deacetylase 3 (HDAC3) via its MBT domain. Here, we show that L3MBTL2 selectively interacts with HDAC3, but not other class I HDACs. An in vitro peptide-binding assay demonstrated the specific association of HDAC3 with methylated histone-K20 tail and L3MBTL2. Furthermore, depletion of HDAC3 resulted in a decrease of methylated K20-H4, as well as an increase in acetylated histone H3. Consequently, HDAC3 knock-down selectively suppressed L3MBTL2-mediated transcriptional repression. Taken together, our results reveal the concerted action of both HDAC3 and L3MBTL2 in histone deacetylation and methylation-dependent transcriptional repression.

Age-related eye diseases (AREDs) are the leading cause of visual impairment in the elderly, affecting the structure of the anterior and posterior segments of the eye, significantly reducing the quality of life of patients, and even leading to irreversible blindness. Typical AREDs include age-related cataract (ARC), dry eye disease (DED), age-related macular degeneration (AMD), glaucoma, and diabetic retinopathy (DR), the global prevalence of which continues to rise, becoming a serious public health concern. SIRT1 is an NAD + dependent deacetylase, which plays an important physiological regulatory role in ocular tissues, mainly affecting gene expression and various cellular processes by regulating the acetylation status of substrate proteins.

Introduction: Aberrant biomechanical force-induced chondrocyte adipogenesis is involved in the development of temporomandibular joint osteoarthritis (TMJ OA). Growth differentiation factor 11 (GDF11) has been implicated in this process. However, whether mechanosensitive histone deacetylase 3 (HDAC3) regulates GDF11 signaling in the context of TMJ OA remains to be elucidated.

Neuroinflammation is vital in vincristine-induced peripheral neuropathy (VIPN). Locally infiltrated macrophages polarize to pro-inflammatory M1-type, release inflammatory cytokines, and contribute to neuropathic pain. Histone deacetylase 3 (HDAC3) regulates macrophage polarization.

Colorectal cancer (CRC) is a predominant malignancy of the digestive tract globally, with primary treatment strategies including surgery, chemotherapy, radiotherapy, targeted therapy, and immunotherapy. Recently, histone deacetylases (HDACs) and their inhibitors (HDACi) have emerged as promising therapeutic targets in CRC. As critical epigenetic regulators, HDACs influence gene expression and cellular processes, thereby affecting tumor initiation, progression, and immune evasion.

TDP-43 is known to bind the mRNA of histone deacetylase 6 (HDAC6), influencing its RNA translation. Many studies suggest that HDAC6 participates in the regulation of autophagy, which we found impaired in sporadic ALS (sALS) patients. Aim of this work is to evaluate the interaction between TDP-43 and HDAC6 mRNA and to evaluate the effect of the up- and down-regulation of HDAC6 on autophagy in SH-SY5Y cells.
