Novel epitranscriptomic and epigenetic therapeutic strategies and targets for ferroptosis in liver fibrosis.

Liver fibrosis is characterized by an excessive accumulation of extracellular matrix (ECM) and the activation of hepatic stellate cells (HSCs), which are influenced by epitranscriptomic and epigenetic factors. Recent advancements in epigenetic and epitranscriptomic research have revealed new opportunities for therapeutic interventions, particularly through the regulation of ferroptosis, a type of programmed cell death that is specifically linked to iron-dependent lipid peroxidation. In the context of liver fibrosis, a progressive scarring process that can progress to cirrhosis and ultimately end-stage liver disease, targeting these regulatory mechanisms to modulate ferroptosis presents a promising therapeutic strategy.

Covalent-Allosteric Inhibitors: Do We Get the Best of Both Worlds?

Covalent-allosteric inhibitors (CAIs) may achieve the best of both worlds: increased potency, long-lasting effects, and reduced drug resistance typical of covalent ligands, along with enhanced specificity and decreased toxicity inherent in allosteric modulators. Therefore, CAIs can be an effective strategy to transform many undruggable targets into druggable ones. However, CAIs are challenging to design.

Immunomodulatory effect of efferocytosis at the maternal-fetal interface.

Efferocytosis is a mechanism by which phagocytes efficiently clear apoptotic cells, averting their secondary necrosis and the subsequent release of potentially immunogenic or cytotoxic substances that can trigger strong immune and inflammatory responses. During efferocytosis, the metabolic pathways of phagocytes are transformed, which, along with the catabolism of apoptotic cargo, can affect their function and inflammatory state. Extensive apoptosis occurs during placental development, and some studies reported the immunomodulatory effects of efferocytosis at the maternal-fetal interface.

Spatiotemporal variation in biomass abundance of different algal species in Lake Hulun using machine learning and Sentinel-3 images.

Climate change and human activities affect the biomass of different algal and the succession of dominant species. In the past, phytoplankton phyla inversion has been focused on oceanic and continental shelf waters, while phytoplankton phyla inversion in inland lakes and reservoirs is still in the initial and exploratory stage, and the research results are relatively few. Especially for mid-to-high latitude lakes, the research is even more blank.

Deciphering the δ-Lactam Formation and lron-Reducing Activity of Spinactins from .

The cyclic structure of non-ribosomal peptides (NRPs) is critical for enhancing their stability and bioactivity, which highlights the importance of exploring NRP cyclization enzymes for natural product discovery. Thioesterases (TEs) are crucial enzymes that catalyze the formation of various lactams, including macrolactams, β-lactams, and γ-lactams; however, their potential to produce other lactam types remains largely unexplored. In this study, we identified spinactin A () and novel derivatives, spinactin B-E (-), from NRRL 18395 and characterized the biosynthetic enzymes involved, particularly a unique TE SncF, responsible for δ-lactam formation.

Targeted mitochondrial function for cardiac fibrosis: An epigenetic perspective.

Mitochondria, commonly referred to as "energy factories"of cells, play a crucial role in the function and survival of cardiomyocytes. However, as research on cardiac fibrosis has advanced, mitochondrial dysfunction(including changes in energy metabolism, calcium ion imbalance, increased oxidative stress, and apoptosis)is now recognized as a significant pathophysiological pathway involved in cardiac remodeling and progression, which also negatively affects the function and structure of the heart. In recent years, research focusing on targeting mitochondria has gained significant attention, offering new approaches for treating cardiac fibrosis.

Vegetation Dynamics and Recovery Potential in Arid and Semi-Arid Northwest China.

The arid and semi-arid regions of northwest China are characterized by sparse vegetation and fragile ecosystems, making them highly susceptible to the impacts of climate change and human activities. Based on observed meteorological data, the Normalized Difference Vegetation Index (NDVI), the Lund-Potsdam-Jena dynamic global vegetation model (LPJ), a vegetation recovery potential model, and the MK trend test method, this study investigated the spatiotemporal distribution of vegetation recovery potential in northwest China and its relationship with global warming and increasing precipitation. The results indicated that vegetation in northwest China significantly increased, with greening closely related to trends in warming and wetting during 1982-2019.

Epigenetic regulation of mitochondrial fission and cardiac fibrosis via sFRP3 promoter methylation.

In the process of cardiac fibrosis, the balance between the Wnt/β-catenin signalling pathway and Wnt inhibitory factor genes plays an important role. Secreted frizzled-related protein 3 (sFRP3), a Wnt inhibitory factor, has been linked to epigenetic mechanisms. However, the underlying role of epigenetic regulation of sFRP3, which is crucial in fibroblast proliferation and migration, in cardiac fibrosis have not been elucidated.
