Summary: The transcription factor NRF2 regulates the expression of genes encoding epigenetic regulatory factors by binding to their promoter regions containing ARE sequences. This study confirms NRF2's role in regulating histone deacetylases, DNA methyltransferases, and proteins involved in microRNA biogenesis. Additionally, NRF2 is found to be involved in the degradation of miR-155-5p through its interaction with Nfe2l2 mRNA. These findings demonstrate the epigenetic regulatory function of NRF2 and its potential implications for therapeutic strategies.

Summary: Epigenetic regions such as VEGF, EGFR, TGFb, DNMTs, HDAC1/2, and miRNA are innovative druggable targets for building a novel platform of drugs for preventive and regenerative skin health care. Clinical and preclinical trials are being conducted for skin regeneration using epigenetic-based small molecules. Epigenetic writers, eraser targets, and epigenetic readers will play a crucial role in skin regenerative therapy in the near future.

Summary: Many populations worldwide suffer from CNS diseases such as brain tumors, neurodegenerative diseases, and stroke, with a shortage of effective drugs. Histone deacetylases (HDACs) have been extensively studied for their role and therapeutic benefits in the CNS. Recent attention has been given to HDACs as potential drug targets for CNS diseases. This review summarizes the applications of HDACis in CNS diseases and discusses the challenges in developing HDACis with different structures and better blood-brain barrier permeability, in order to promote the development of more effective bioactive HDACis for CNS disease treatment.

Summary: UHRF1, a nuclear multi-domain protein overexpressed in various human cancer types, can be inhibited by two new compounds, AMSA2 and MPB7, which prevent UHRF1/DNMT1 interaction during DNA replication, reduce overall DNA methylation, and induce cell death specifically in cancer cell lines with high levels of UHRF1. These compounds show promise as anti-cancer drugs targeting UHRF1 due to their specificity and effectiveness.

Summary: In recent years, synthetic food colorants have shown wider properties compared to natural equivalents, but their health impact is still not well understood. This study aimed to determine the long-term effects of tartrazine, a commonly used artificial food colorant, on NMRI mice. The results showed significant upregulation of genes in various organs following tartrazine intake, suggesting possible associations with carcinogenesis and neurological disorders.

Summary: Histone deacetylases (HDACs) are epigenetic regulators that affect chromatin condensation and cancer proliferation. HDAC inhibitors are promising drugs for cancer treatment. However, there are limitations and resistance issues in clinical application, leading to the search for new HDAC inhibitors. Kinase inhibitors, when used in combination with HDAC inhibitors, show synergistic anticancer effects.

Summary: The combined treatment of DNA methylation inhibitor hydralazine and histone deacetylase inhibitors panobinostat and valproic acid showed synergistic growth inhibitory effects on prostate cancer cells, particularly in DU145 cells. This suggests that these drugs may be potential therapeutic tools to counteract the progression of prostate cancer.

Summary: The novel homozygous 4-bp deletion in DDHD1 was identified as responsible for spastic paraplegia type 28 (SPG28). Knockout mice with a premature stop codon similar to the patient showed decreased foot-base angle and reduced LPI 20:4 (sn-2) levels in the cerebra. Changes in gene expression related to nervous system and cell-cell communication were also observed, suggesting a potential role of reduced downstream signaling in the pathogenesis of SPG28.

Summary: ICF syndrome is a rare genetic disorder characterized by the frequent appearance of multiradial chromosomes in activated lymphocytes, which may result from mutations in DNMT3B, ZBTB24, CDCA7, or HELLS genes. Defects in DNA methylation and impaired maintenance DNA methylation could lead to chromosomal abnormalities and instability in patients with this syndrome.

Summary: DNA methylation profiling is used to improve diagnosis of patients with inherited neurodevelopmental disorders and guide mutation screening. Mutations in enzymes with similar or intertwined functions can lead to distinct DNAme signatures and consequences, highlighting functional links between different enzymes and suggesting possible redundant or complementary functions in humans.

Summary: This study identified UHRF1 as a novel causative gene of Immunodeficiency, centromeric instability and facial anomalies (ICF) syndrome. By analyzing a patient with atypical symptoms, two previously unreported mutations in the UHRF1 gene were identified, which led to abnormal methylation and protein conformation changes. Through further analysis of patient cells and protein interactions, the importance of UHRF1 in the regulation of CG methylation was confirmed.

Summary: In this study, the researchers found that the specific knockout of the Uhrf1 gene in oocytes affects chromosome segregation, cleavage division, and preimplantation viability in mice. Further investigations showed that these phenotypes were associated with cytoplasmic defects and not nuclear defects. Proteomic analysis of the knockout oocytes revealed down-regulation of proteins related to microtubules and disorganization of the cytoplasmic architecture, including mislocalization of mitochondria, endoplasmic reticulum, and maternal complex components.
