Convertini P et. al. (August 2023). ACLY as a modulator of liver cell functions and its role in Metabolic Dysfunction-Associated Steatohepatitis J Transl Med. 21(1):568.
This study explores the role of the immunometabolic enzyme ATP citrate lyase (ACLY) in liver function and its involvement in Metabolic Dysfunction-Associated Steatohepatitis (MASH). The study found that ACLY inhibition can reverse lipid accumulation, oxidative damage, and reduce the secretion of inflammatory cytokines in liver cells, suggesting its potential diagnostic and therapeutic significance for MASH.

Jia Q et. al. (August 2023). A DNA adenine demethylase impairs PRC2-mediated repression of genes marked by a specific chromatin signature Genome Biol. 24(1):198.
The article investigates a DNA adenine demethylase's role in disrupting the Polycomb Repressive Complex 2 (PRC2)-mediated gene repression, particularly for genes marked by a specific chromatin signature. The study reveals that this demethylase interferes with the normal repression of genes with the identified chromatin signature, shedding light on its regulatory impact in epigenetic processes.

Grigorash BB et. al. (August 2023). p16High senescence restricts cellular plasticity during somatic cell reprogramming Nat Cell Biol.
The article explores the role of p16High senescent cells in somatic cell reprogramming and cellular plasticity. By removing p16High cells, researchers were able to induce the reprogramming of somatic cells into totipotent-like stem cells capable of forming implantation-competent blastoids and contributing to embryonic and extraembryonic lineages, suggesting that the presence of these senescent cells limits cellular plasticity during reprogramming and that their depletion can promote a more versatile cellular state.

Chakraborty S et. al. (November 2023). Trained immunity of alveolar macrophages enhances injury resolution via KLF4-MERTK-mediated efferocytosis J Exp Med. 220(11)
The study explores how prechallenged lung-resident alveolar macrophages (AMs) exhibit trained immunity, enhancing their ability to resolve injury following repeated pathogen exposures. This trained immunity involves the expansion of a specific AM subset with proresolving characteristics and increased efferocytosis capacity mediated by the transcription factor KLF4 and the efferocytosis receptor MERTK, ultimately reducing inflammatory lung injury in response to pathogenic challenges.

Sun X et. al. (August 2023). DNA methylation cooperates with H3K9me2 at HCN4 promoter to regulate the differentiation of bone marrow mesenchymal stem cells into pacemaker-like cells PLoS One. 18(8):e0289510.
The article investigates the mechanisms behind the differentiation of bone marrow mesenchymal stem cells (BMSCs) into pacemaker-like cells, focusing on DNA methylation and histone methylation. It finds that changes in DNA and H3K9 methylation occur in the promoter region of the pacemaker cell-specific gene HCN4, and inhibiting these methylation processes can enhance the activity of the HCN4 promoter and improve the efficiency of inducing BMSCs into pacemaker-like cells, suggesting the potential for optimizing in vitro applications of pacemaker-like cells through combined methylation strategies.

Han X et. al. (August 2023). Downregulation of MGMT expression by targeted editing of DNA methylation enhances temozolomide sensitivity in glioblastoma Neoplasia. 44:100929.
In this study, researchers explored a novel approach to enhance the effectiveness of temozolomide (TMZ) chemotherapy in glioblastoma, a highly aggressive brain tumor. They utilized the CRISPRoff genome editing tool to specifically reduce the DNA methylation levels in the MGMT gene promoter, which resulted in decreased MGMT expression and, consequently, increased sensitivity of glioblastoma cells to TMZ, potentially offering a promising strategy to overcome chemotherapy resistance in this challenging cancer.

Zhu WH et. al. (July 2023). Erythroid-transdifferentiated myeloid cells promote portal vein tumor thrombus in hepatocellular carcinoma Theranostics. 13(13):4316-4332.
The article investigates the role of CD71+ erythroid progenitor cells (EPCs) in hepatocellular carcinoma (HCC), particularly in the development of portal vein tumor thrombus (PVTT). It finds that a subset of CD45+EPCs in the HCC microenvironment undergo erythroid-to-myeloid transdifferentiation and are induced by HCC macrophages to migrate to the tumor microenvironment, where they promote PVTT by compromising blood vessel endothelium, enhancing coagulation, and facilitating HCC cell migration, suggesting a novel mechanism for PVTT in HCC.

Kapuganti RS et. al. (August 2023). Role of clusterin gene 3'-UTR polymorphisms and promoter hypomethylation in the pathogenesis of pseudoexfoliation syndrome and pseudoexfoliation glaucoma Biochim Biophys Acta Gene Regul Mech. :194980.
The study investigates the genetic and epigenetic factors related to clusterin (CLU) in the pathogenesis of pseudoexfoliation syndrome (PEXS) and pseudoexfoliation glaucoma (PEXG). The study identifies specific 3'-UTR single nucleotide polymorphisms (SNPs) in the CLU gene associated with PEXS and PEXG, as well as promoter hypomethylation of CLU in PEX patients, suggesting different molecular mechanisms contributing to pseudoexfoliation pathology.
