Isshiki et al. and Porazzi et al. report that inhibiting enhancer of zeste homolog 1 (EZH1) and EZH2 enhances chimeric antigen receptor (CAR)/T cell receptor (TCR)-based therapies by reprogramming tumors to be more immunogenic and improving T cell phenotype and demonstrate the efficacy of this combination in preclinical models across hematologic and solid cancers. Clinical trials are ongoing to evaluate its safety and therapeutic potential.

Antigen-experienced memory B-cells (MBC) are endowed with enhanced functional properties compared to naïve B cells and play an important role in the humoral response. However, the epigenetic enzymes and programs that govern their rapid differentiation are incompletely understood. Here, the role of the histone H3 lysine 27 methyltransferase EZH2 in the formation of MBC in response to an influenza infection was determined in Mus musculus.

Background: Polycystic ovary syndrome (PCOS) is a common endocrinometabolic disorder affecting women of reproductive age, characterized by hormonal imbalances, irregular menstrual cycles, and often, infertility. Hypothalamic amenorrhea, a condition marked by the cessation of menstruation due to disruptions in the hypothalamic-pituitary-gonadal axis, is a frequent manifestation in PCOS. Probiotics, beneficial microorganisms known for improving metabolic health, have shown promise in restoring hormonal balance and enhancing fertility.

A previously reported clinical trial in familial adenomatous polyposis (FAP) patients treated with erlotinib plus sulindac (ERL + SUL) highlighted immune response/interferon-γ signaling as a key pathway. In this study, we combine intermittent low-dose ERL ± SUL treatment in the polyposis in rat colon (Pirc) model with mechanistic studies on tumor-associated immune modulation. At clinically relevant doses, short-term (16 weeks) and long-term (46 weeks) ERL ± SUL administration results in near-complete tumor suppression in Pirc colon and duodenum (p < 0.

Brain injuries can result from accidents, warfare, sports injuries, or brain diseases. Identifying regeneration-associated genes (RAGs) during epigenome remodeling upon brain injury could have a significant impact on reducing neuronal death and subsequent neurodegeneration for patients with brain injury. We previously identified several WNT genes as RAGs involved in the neurite regrowth of injured cortical neurons.

Cancer remains a major global health challenge, with prostate cancer, lung cancer, colorectal cancer, and breast cancer accounting for nearly half of all diagnoses. Despite advancements in cancer treatment, metastasis to distant organs continues to be the leading cause of cancer-related mortality. The progression of cancer involves the alteration of numerous genes, with dynamic changes in chromatin organization and histone modifications playing a critical role in regulating cancer-associated genes.
