Summary: A CRISPR-Cas9 screen in mouse tumour models treated with immune checkpoint blockade identified SETDB1 as an epigenetic checkpoint protein that suppresses tumour-intrinsic immunogenicity. Loss of SETDB1 leads to derepression of immune-stimulating genes and triggers TE-specific cytotoxic T cell responses, suggesting it as a potential target for immunotherapy in cancer treatment.

Summary: Epigenetic changes associated with histone modifications are important in the emergence and maintenance of various cancer types. Inhibitors of enzymes involved in these modifications are promising for anticancer drug development. This review explores the main features of common histone modifications and their role in malignant neoplasms, discussing strategies for inhibitor development and analyzing the use of multitarget drugs as the most promising strategy.

Summary: Parkinson's disease (PD) is a multifactorial disease caused by a complex interplay between genetic and epigenetic factors. Recent studies have revealed the epigenetic mechanisms involved in PD, such as DNA methylation, histone modifications, and microRNA (miRNA) regulation. Epigenetic regulators could be potential therapeutic targets in neurodegenerative disorders. This review summarizes the mechanisms of epigenetic regulation in PD and discusses the use of inhibitors and activators of these regulators, as well as the neuroprotective effects of small molecule epigenetic modulators. Additionally, the contribution of miRNAs to the underlying mechanisms of PD and miRNA-based therapies are also discussed.

Summary: PALI1 is a newly identified accessory protein that plays a role in advanced prostate cancer. It competes with JARID2 for binding to the PRC2 core subunit SUZ12 and interacts with the H3K9 methyltransferase G9A, forming a unique super-complex involved in dual H3K9/K27 methylation and gene repression. PALI1 and G9A promote prostate cancer cell proliferation and invasion, and drive tumor growth in xenograft models.

Summary: Glioblastoma is highly resistant to standard therapies and the durability of response to the best chemotherapy agent, Temozolomide, is often short-lived due to tumor resistance. The need for therapies that can provide synergy to chemoradiation is urgent, as adaptive resistance evolution in GBM is facilitated through treatment-induced epigenetic modifications. Understanding and targeting these epigenetic modifications associated with GBM resistance is a top priority.

Summary: This review focuses on the interconnections between epigenetics and alternative splicing in the development of cancer. It discusses the mechanisms involved in these interconnections and the potential diagnostic and therapeutic tools that can be derived from them. The reversible nature of epigenetic alterations and the possibility of correcting aberrant alternative splicing offer promising therapeutic possibilities for cancer treatment.

Summary: The emergence of a nucleosome-based chromatin structure during the evolutionary transition from prokaryotes to eukaryotes plays a crucial role in adaptive responses to environmental influence through epigenetic mechanisms involving histones. The overwhelming number of post-translational modifications at multiple residues of histones and their implications in nucleosome dynamics and chromatin processes are discussed in this review.

Summary: In this study, the authors demonstrated a causal effect of epigenetic modifications on mutation rates in fungal pathogens, as well as the impact of temperature stress and cytosine methylation on the rate and location of spontaneous mutations in the genome. Additionally, they found that histone modifications and transposable elements can significantly affect mutation rates.

Summary: H3K9 methyltransferases play crucial roles in genome stability, cell type-specific gene expression, and non-histone methylation. They are involved in histone modification and regulate the methylation of various non-histone targets, contributing to genome regulation and cellular functions.

Summary: The rixosome and PRC1 silencing complexes are associated with deSUMOylating and deubiquitinating enzymes, SENP3 and USP7, respectively. The enzymatic activities of SENP3 and USP7 are required for silencing of Polycomb target genes. SUMOylation and ubiquitination regulate the assembly and activities of the rixosome and Polycomb complexes.

Summary: Maintenance of appropriate cell states involves epigenetic mechanisms, including Polycomb-group (PcG)-mediated transcriptional repression. This study reveals the association between the p300/CREB-binding protein (CBP) co-activator and PcG regions in Drosophila and mouse cells. CBP stabilizes Pol II at PcG-bound repressive sites and promotes Pol II pausing, which are necessary for R-loop formation and nucleosome depletion at Polycomb Response Elements (PREs), thereby supporting PcG-mediated silencing.

Summary: Ki-67 assessment plays a key role in the diagnosis of neuroendocrine neoplasms (NENs) from all anatomic locations. Digital pathology combined with machine learning has shown to be highly accurate and reproducible for evaluating Ki-67 in NENs. In this systematic review, the advantages of digital image analysis (DIA) in assessing Ki-67 in pancreatic NENs (PanNENs) were highlighted, including improved standardization and reliability, as well as increased speed and practicality compared to manual counting. However, limitations such as higher costs and operator qualification issues need to be addressed. A comparative meta-analysis showed a high concordance between DIA and manual counting. These findings support the widespread adoption of validated DIA methods for Ki-67 assessment in PanNENs.

Summary: This study evaluated the usefulness of immunohistochemistry (IHC) using the BRAF VE1 mutant-specific antibody as a diagnostic adjunct in mandibular ameloblastoma. The study found that the BRAF(V600E) mutation is more frequent in mandibular ameloblastoma and less frequent in maxillary ameloblastoma. BRAF VE1 IHC is a highly accurate tool for the diagnosis of mandibular ameloblastoma.

Summary: The tumor formerly known as cauda equina paraganglioma was recently renamed as cauda equina neuroendocrine tumor (CENET) based on distinct biological and genetic properties. All tumors tested were positive for INSM1, synaptophysin, chromogranin A, SSTR2, and CD56 as well as at least 1 keratin (AE1/AE3, CAM5.2).

Summary: The assessment of cell differentiation in endocrine neoplasms involves the identification of cell structure, specific transcription factors, hormones, and enzymes. Differentiation status serves as prognostic and predictive factors for endocrine neoplasms. Hormones can act as biomarkers for clinical surveillance and loss of differentiated hormone production can indicate dedifferentiation and aggressiveness of the tumor. Differentiated endocrine cells express targets for therapy, providing opportunities for targeted treatment.

Summary: In this study, the researchers found that 4E-BP1/2 proteins play a critical role in the proliferation of mouse CD8(+) T cells and the development of antiviral effector function. They also discovered that the translation of genes related to mitochondrial biogenesis is impaired in T cells derived from 4E-BP1/2-deficient mice.
