简介

Responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Histone deacetylases act via the formation of large multiprotein complexes. Involved in muscle maturation by repressing transcription of myocyte enhancer MEF2C. During muscle differentiation, it shuttles into the cytoplasm, allowing the expression of myocyte enhancer factors. Involved in the MTA1-mediated epigenetic regulation of ESR1 expression in breast cancer. Serves as a corepressor of RARA and causes its deacetylation (PubMed:28167758). In association with RARA, plays a role in the repression of microRNA-10a and thereby in the inflammatory response (PubMed:28167758).

Histone deacetylases (HDACs) and sirtuins (SIRTs) are important epigenetic regulators of cancer pathways. There is a limited understanding of how transcriptional regulation of their genes is affected by chemotherapeutic agents, and how such transcriptional changes affect tumour sensitivity to drug treatment. We investigated the concerted transcriptional response of HDAC and SIRT genes to 15 approved antitumor agents in the NCI-60 cancer cell line panel. Antitumor agents with diverse mechanisms of action induced upregulation or downregulation of multiple HDAC and SIRT genes. HDAC5 was upregulated by dasatinib and erlotinib in the majority of the cell lines. Tumour cell line sensitivity to kinase inhibitors was associated with upregulation of HDAC5, HDAC1, and several SIRT genes. We confirmed changes in HDAC and SIRT expression in independent datasets. We also experimentally validated the upregulation of HDAC5 mRNA and protein expression by dasatinib in the highly sensitive IGROV1 cell line. HDAC5 was not upregulated in the UACC-257 cell line resistant to dasatinib. The effects of cancer drug treatment on expression of HDAC and SIRT genes may influence chemosensitivity and may need to be considered during chemotherapy.

Infertility caused by lipopolysaccharide (LPS) exposure due to infection is endangering male fertility worldwide, but the mechanism remains unclear. The blood-testis barrier (BTB) is essential for maintaining spermatogenesis and male fertility. In the present study, we showed that LPS (5.0 mg/kg) treatment markedly down-regulated the expression of BTB-related proteins, expanded the biotin penetration distance and caused histopathological injury in seminiferous tubules in mouse testes. Notably, testicular macrophage M1 polarization induced by LPS seems to be related to BTB damage, which was well confirmed by co-culture of RAW264.7 and TM4 cells in vitro. Interestingly, a low-dose LPS (0.1 mg/kg) pretreatment attenuated down-regulation of BTB-related proteins expression and histopathological injury and shorten biotin penetration distance in seminiferous tubules caused by LPS. Correspondingly, a low-dose LPS pretreatment suppresses testicular macrophage M1 polarization induced by LPS in mouse testes. Further experiments revealed that histone deacetylase 5 (HDAC5) was markedly down-regulated at 2 h and slightly down-regulated at 8 h, but up-regulated at 24 h in mouse testes after LPS treatment. Additionally, low-dose LPS pretreatment against the down-regulation of HDAC5 protein caused by LPS treatment. Notably, the suppressed testicular macrophage M1 polarization by low-dose LPS pretreatment was broken by BRD4354, a specific inhibitor of HDAC5 in vitro. These results suggest suppressed testicular macrophage M1 polarization by HDAC5 enforces insensitivity to LPS-elicited BTB damage.

Akkermansia muciniphila ameliorates colonic injury in mice with DSS-induced acute colitis by blocking macrophage pro-inflammatory phenotype switching via the HDAC5/DAB2 axis

Akkermansia muciniphila (A. muciniphila), a probiotic, has been linked to macrophage phenotypic polarization in different diseases. However, the role and mechanisms of A. muciniphila in regulating macrophage during ulcerative colitis (UC) are not clear. This research aimed to examine the impact of A. muciniphila on dextran sulfate sodium (DSS)-induced acute colitis and elucidate the underlying mechanism related to macrophage phenotypic polarization. A. muciniphila inhibited weight loss, increased disease activity index, and ameliorated inflammatory injury in colonic tissues in mice induced with DSS. Furthermore, A. muciniphila reduced macrophage M1 polarization and ameliorated epithelial barrier damage in colonic tissues of DSS-induced mice through inhibition of histone deacetylase 5 (HDAC5). In contrast, the effect of A. muciniphila was compromised by HDAC5 overexpression. HDAC5 deacetylated H3K9ac modification of the disabled homolog 2 (DAB2) promoter, which led to repressed DAB2 expression. DAB2 overexpression blocked HDAC5-induced pro-inflammatory polarization of macrophages, whereas knockdown of DAB2 resulted in the loss of effects of A. muciniphila against colonic injury in DSS-induced mice. Taken together, A. muciniphila-induced loss of HDAC5 hampered the deacetylation of DAB2 and enhanced the expression of DAB2. Our findings propose that A. muciniphila may be a possible probiotic agent for alleviating DSS-induced acute colitis.

前列腺癌雄激素受体靶向治疗耐药的潜在机制

肿瘤的突变负担和异质性已被认为是对许多靶向治疗产生耐药性的原因。胞嘧啶脱氨酶APOBEC蛋白与超过70%的人类癌症的突变特征有关。然而，癌细胞如何劫持APOBEC介导的突变机制以促进肿瘤异质性，从而促进治疗耐药性的机制尚不清楚。2023年7月20日，德克萨斯大学西南医学中心牟平团队在Cancer Cell 在线发表题为“Loss of SYNCRIP unleashes APOBEC-driven mutagenesis, tumor heterogeneity, and AR-targeted therapy resistance in prostate cancer”的研究论文，该研究发现SYNCRIP是一种内源性分子制动器，可以抑制前列腺癌(PCa)中APOBEC驱动的突变。在SYNCRIP缺失的PCa细胞中，过度激活的APOBEC3B是一个关键的突变子，代表了PCa中一些常见突变基因(包括FOXA1、EP300)驱动突变的分子来源。功能筛选确定了APOBEC3B突变的PCa中雄激素受体(AR)靶向治疗耐药的8个关键驱动因素：BRD7、CBX8、EP300、FOXA1、HDAC5、HSF4、STAT3和AR。这些结果揭示了APOBEC驱动的突变释放的细胞内在机制，该机制在赋予PCa AR靶向治疗耐药中起重要作用。针对驱动癌基因的治疗方法的发展已经彻底改变了许多癌症的临床管理；然而，它们的反应的幅度和持续时间仍然是可变的，并且不可避免地发生抵抗。大量证据表明，突变负担的增加和遗传异质性既是抗性的燃料，也是抗性的来源。因此，阐明这种增加的诱变和遗传异质性的分子起源和机制对于培养下一代抗癌疗法和克服耐药性至关重要。遗传异质性可能源于许多癌症的基因组不稳定性。新出现的数据表明，肿瘤细胞可以劫持稳态调节机制，从而加强突变，作为促进基因组不稳定的可能途径。这种机制的一个重要例子是脱氨酶APOBEC蛋白。在超过70%的人类癌症中观察到APOBEC驱动的突变模式增加。然而，癌细胞如何劫持APOBEC介导的突变机制以促进肿瘤异质性，从而促进治疗耐药性的机制在很大程度上仍然未知。机理模式图（图源自Cancer Cell ）该研究发现前列腺癌(PCa)中突触结合细胞质RNA相互作用蛋白(SYNCRIP)的频繁丢失是一个分子驱动事件，释放APOBEC驱动的突变。在SYNCRIP缺失的肿瘤中，过度激活的APOBEC3B是PCa(包括FOXA1、EP300和AR)中频繁驱动突变的关键突变子和分子来源。研究结果确定了8个由APOBEC3B失调引起的PCa雄激素受体(AR)靶向治疗耐药的关键驱动因素。与传统认识相反，单细胞转录组学分析显示，APOBEC3B诱导的FOXA1驱动突变胜过其他驱动突变，最终主导耐药肿瘤。总的来说，这些发现揭示了控制肿瘤突变负担和异质性的细胞内在机制，并将SYNCRIP和过度激活的APOBEC3B驱动的突变与经常观察到的赋予AR靶向治疗耐药性的驱动突变在机制上联系起来。文章来源“iNature”责编|文竞择校对|文竞择End 往期精选围观历史性突破！不需卵子和精子就可以合成人类胚胎热文富豪用儿子血浆“回春”科学吗？Science：血液牛磺酸缺乏驱动衰老热文世界首例！35岁的她，通过机器人操刀移植的子宫，成功诞下宝宝热文‍为了避免心脏骤停，53岁的他成为“第一个”植入开创性除颤器的心脏病患者热文首次披露！175家生物制药公司的薪资数据：薪资中位数达20万美元点击“阅读原文”，了解更多~
