Abstract
Pelodiscus sinensis (P. sinensis) is a commonly cultivated turtle species with a habit of hibernation. To study the changes in histone expression and methylation of P. sinensis during hibernation induction, a model was established by artificial induction. Physiological and metabolic indices were measured, and the expression and localization of histone (H1, H2A, H2B, H3, and H4) and methylation-related genes (ASH2L, KMT2A, KMT2E, KDM1A, KDM1B, and KDM5A) were measured by quantitative PCR, immunohistochemistry, and Western blot analysis. The results indicated that the metabolism, antioxidation index, and relative expression of histone methyltransferase were significantly decreased (p < 0.05), whereas the activity and expression of histone demethyltransferase were significantly increased (p < 0.05). Although our results showed significant changes in physiological and gene expression after hibernation induction, we could not confirm that P. sinensis entered deep hibernation. Therefore, for the state after cooling-induced hibernation, cold torpor might be a more accurate description. The results indicate that the P. sinensis can enter cold torpor through artificial induction, and the expression of histones may promote gene transcription. Unlike histones expressed under normal conditions, histone methylation may activate gene transcription during hibernation induction. Western blot analysis revealed that the ASH2L and KDM5A proteins were differentially expressed in the testis at different months (p < 0.05), which may perform a role in regulating gene transcription. The immunohistochemical localization of ASH2L and KDM5A in spermatogonia and spermatozoa suggests that ASH2L and KDM5A may perform a role in mitosis and meiosis. In conclusion, this study is the first to report changes in histone-related genes in reptiles, which provides insight for further studies on the physiological metabolism and histone methylation regulation of P. sinensis during the hibernation induction and hibernation period.

Abstract
C/EBP-homologous protein (CHOP) and histone H3 lysine 4 (H3K4) methylation have been verified to be correlated with apoptosis, whereas their biological function in arsenic-induced hepatocyte apoptosis through the mitochondrial pathway is still unclear. This study aimed to explore the specific regulatory mechanism of CHOP and H3K4me1/2 in arsenic-induced mitochondrial apoptosis in hepatocytes. Apoptosis and proliferation results showed arsenic promoted apoptosis and inhibited cell growth in BRL-3A cells. Meanwhile, arsenic treatment significantly upregulated the 78-kDa glucose-regulated protein (GRP78), CHOP, su(var)-3-9,enhancer-of-zeste,trithorax (SET) domain containing 7/9 (SET7/9), H3K4me1/2, BIM and BAX expression, while markedly downregulated lysine-specific histone demethylase 1 (LSD1) and BCL2 expression. After down-regulating CHOP, LSD1, and (su(var)-3-9,enhancer-of-zeste,trithorax) domain-containing protein 7/9 (SET7/9) in BRL-3A cells by siRNA, silencing CHOP and SET7/9 notably attenuated the pro-apoptotic and anti-proliferative effects of arsenic treatment on BRL-3A cells, which was reversed after inhibiting LSD1. In addition, our results suggested that knockdown of CHOP altered the expression of mitochondrial-associated proteins BCL2 and BIM, whereas knockdown of LSD1 and SET7/8 regulated the level of H3K4me1/2 modification and BAX protein. Coupled with chromatin immunoprecipitation results, we found that the level of CHOP in the promoter regions of BCL2 and BIM was significantly increased in BRL-3A cells exposed to 30 µmol/L NaAsO2 for 24 h, whereas the levels of H3K4me1/2 in the promoter regions of BAX were unchanged. Collectively, these data indicated that arsenic triggered the mitochondrial pathway to induce hepatocyte apoptosis by up-regulating the levels of CHOP and H3K4me1/2.

[PMID: 33318631 PMCID: PMC8080763 DOI: 10.1038/s12276-020-00542-2] [Citation(s) in RCA: 80] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 10/21/2020] [Accepted: 11/03/2020] [Indexed: 12/19/2022] Open
Abstract
Lysine-specific histone demethylase 1 (LSD1) represents the first example of an identified nuclear protein with histone demethylase activity. In particular, it plays a special role in the epigenetic regulation of gene expression, as it removes methyl groups from mono- and dimethylated lysine 4 and/or lysine 9 on histone H3 (H3K4me1/2 and H3K9me1/2), behaving as a repressor or activator of gene expression, respectively. Moreover, it has been recently found to demethylate monomethylated and dimethylated lysine 20 in histone H4 and to contribute to the balance of several other methylated lysine residues in histone H3 (i.e., H3K27, H3K36, and H3K79). Furthermore, in recent years, a plethora of nonhistone proteins have been detected as targets of LSD1 activity, suggesting that this demethylase is a fundamental player in the regulation of multiple pathways triggered in several cellular processes, including cancer progression. In this review, we analyze the molecular mechanism by which LSD1 displays its dual effect on gene expression (related to the specific lysine target), placing final emphasis on the use of pharmacological inhibitors of its activity in future clinical studies to fight cancer. Further research into the complex structure and behavior of an enzyme involved in gene regulation could improve future cancer therapies. The modification of chromosomal proteins known as histones can fundamentally change gene expression and influence the progression of diseases such as cancer. Bruno Perillo at the Italian National Research Council, Naples, Italy, and co-workers reviewed understanding of the structurally complex enzyme lysine-specific histone demethylase 1 A (LSD1), which interacts with multiple targets including histones. LSD1 removes methyl groups from histones, fine-tuning gene expression and influencing protein activity. The overexpression of LSD1 is linked to cancer development, particularly in aggressive cancers, and inhibiting LSD1 has shown promise in slowing progression and cancer spread. The researchers call for further research into the complexities of LSD1 activity, both in cancers and normal cell function.

Abstract
The cell cycle is an orchestrated process that replicates DNA and transmits genetic information to daughter cells. Cell cycle progression is governed by diverse histone modifications that control gene transcription in a timely fashion. Histone modifications also regulate cell cycle progression by marking specific chromatic regions. While many reviews have covered histone phosphorylation and acetylation as regulators of the cell cycle, little attention has been paid to the roles of histone methylation in the faithful progression of mitosis. Indeed, specific histone methylations occurring before, during, or after mitosis affect kinetochore assembly and chromosome condensation and segregation. In addition to timing, histone methylations specify the chromatin regions such as chromosome arms, pericentromere, and centromere. Therefore, spatiotemporal programming of histone methylations ensures epigenetic inheritance through mitosis. This review mainly discusses histone methylations and their relevance to mitotic progression.

FLI-06 suppresses proliferation, induces apoptosis and cell cycle arrest by targeting LSD1 and Notch pathway in esophageal squamous cell carcinoma cells. Biomed Pharmacother 2018; 107:1370-1376.

Abstract
Aberrant activation of the Notch signaling plays an important role in progression of esophageal squamous cell carcinoma (ESCC) and may represent a potential therapeutic target for ESCC. FLI-06 is a novel Notch inhibitor, preventing the early secretion of Notch signaling. However, little information about the antitumor activity of FLI-06 has been reported so far. To evaluate the anti-tumor activity and possible molecular mechanism of FLI-06 to ESCC cells, the effects of FLI-06 on cell viability, apoptosis and cell cycle were evaluated by CCK-8 and flow cytometry assays, respectively, in ESCC cell lines ECa109 and EC9706, and the expressions of proteins in Notch signaling pathway and LSD1 were investigated after cells were treated with FLI-06 by Western blotting. The results showed that FLI-06 blocked proliferation, induced apoptosis and G1 phase arrest of ESCC cells in a dose-dependent manner. Mechanistically, we found FLI-06 could inhibit Notch signaling pathway by decreasing the expressions of Notch3, DTX1 and Hes1. Interestingly, we also found that the expression of LSD1 (histone lysine specific demethylase 1), which is dysregulated in multiple tumors, was also inhibited by FLI-06. In addition, inhibition of Notch pathway by γ-secretase inhibitor GSI-DAPT could also inhibit LSD1 expression. The current study demonstrated that FLI-06 exerts antitumor activity on ESCC by inhibiting both LSD1 and Notch pathway, which provides the theory support for the treatment of ESCC with FLI-06.

Abstract
Malignant gliomas are highly lethal cancers worldwide as tumor cells infiltrate to healthy brain tissue invariably. Histone demethylase KDM5A as an oncogene or tumor suppressor in cancer still has been controversial. KDM5A may have a different function in different type cancer cells. However, the specific roles of KDM5A in the progression of glioma remain undiscovered. In this study, we found that compared with primary glioma, metastasis glioma had low KDM5A levels. Besides, lower KDM5A levels were linked to poor survival in glioma cancer patients, indicating that KDM5A is a new prognostic marker for glioma cancer. KDM5A knockdown increases the invasive abilities of glioma cancer cells and changes the EMT markers. A mechanism, KDM5A suppressing the expression of ZEB1, and its catalytic activity is indispensable for anti-invasive function. Our study revealed that histone demethylase KDM5A exerts anti-invasiveness function partly through repressing oncogenic ZEB1 expression by mediating H3K4 demethylation. We also demonstrate that ZEB1 play a crucial role in KDM5A induced function. In summary, in this study, we showed that KDM5A has a crucial role in glioma and therefore may serve as a novel therapeutic target and prognostic marker in glioma.
