The highly complex life cycle of the human malaria parasite, , is based on an orchestrated and tightly regulated gene expression program. In general, eukaryotic transcription regulation is determined by a combination of sequence-specific transcription factors binding to regulatory DNA elements and the packaging of DNA into chromatin as an additional layer. The accessibility of regulatory DNA elements is controlled by the nucleosome occupancy and changes of their positions by an active process called nucleosome remodeling. These epigenetic mechanisms are poorly explored in The parasite genome is characterized by an extraordinarily high AT-content and the distinct architecture of functional elements, and chromatin-related proteins also exhibit high sequence divergence compared to other eukaryotes. Together with the distinct biochemical properties of nucleosomes, these features suggest substantial differences in chromatin-dependent regulation. Here, we highlight the peculiarities of epigenetic mechanisms in , addressing chromatin structure and dynamics with respect to their impact on transcriptional control. We focus on the specialized chromatin remodeling enzymes and discuss their essential function in gene regulation.

It is known that inhibition of the endoplasmic reticulum transmembrane signaling protein (ERN1) suppresses the glioblastoma cells proliferation. The present study aims to investigate the impact of inhibition of ERN1 endoribonuclease and protein kinase activities on the , , and gene expression in U87MG glioblastoma cells with an intent to reveal the role of ERN1 signaling in the regulation of expression of these genes. The U87MG glioblastoma cells with inhibited ERN1 endoribonuclease (dnrERN1) or both enzymatic activities of ERN1 (endoribonuclease and protein kinase; dnERN1) were used.

For the effective growth of malignant tumors, including glioblastoma, the necessary factors involve endoplasmic reticulum (ER) stress, hypoxia, and the availability of nutrients, particularly glucose. The ER degradation enhancing alpha-mannosidase like protein 1 (EDEM1) is involved in ER-associated degradation (ERAD) targeting misfolded glycoproteins for degradation in an N-glycan-independent manner. EDEM1 was also identified as a new modulator of insulin synthesis and secretion.

Itaconate restrains acute proinflammatory activation of microglia MG after traumatic brain injury in mice.

Traumatic brain injury (TBI) rapidly triggers proinflammatory activation of microglia, contributing to secondary brain damage post-TBI. Although the governing role of energy metabolism in shaping the inflammatory phenotype and function of immune cells has been increasingly recognized, the specific alterations in microglial bioenergetics post-TBI remain poorly understood. Itaconate, a metabolite produced by the enzyme aconitate decarboxylase 1 [IRG1; encoded by immune responsive gene 1 ()], is a pivotal metabolic regulator in immune cells, particularly in macrophages.

Heterogeneous cellular responses to hyperthermia support combined intraperitoneal hyperthermic immunotherapy for ovarian cancer mouse models.

The benefit of hyperthermic intraperitoneal chemotherapy (HIPEC) in ovarian cancer remains controversial, hindering the development of rational combination therapies based on hyperthermia (HT). This study reports the preliminary results of the neoadjuvant HIPEC (NHIPEC) trial (ChiCTR2000038173), demonstrating enhanced tumor response in high-grade serous ovarian cancer with NHIPEC. Through single-cell RNA sequencing analysis, we identified both homogeneous and heterogeneous cellular responses to HT within the tumor and microenvironment.

Interstitial lung disease (ILD) consists of a group of immune-mediated disorders that can cause inflammation and progressive fibrosis of the lungs, representing an area of unmet medical need given the lack of disease-modifying therapies and toxicities associated with current treatment options. Tissue-specific splice variants (SVs) of human aminoacyl-tRNA synthetases (aaRSs) are catalytic nulls thought to confer regulatory functions. One example from human histidyl-tRNA synthetase (HARS), termed HARS because the splicing event resulted in a protein encompassing the WHEP-TRS domain of HARS (a structurally conserved domain found in multiple aaRSs), is enriched in human lung and up-regulated by inflammatory cytokines in lung and immune cells.
