LBH589 reduces oxidized mitochondrial DNA and suppresses NLRP3 inflammasome activation to relieve pulmonary inflammation.

The NOD-like receptor protein (NLRP)3 inflammasome plays a critical role in acute respiratory distress syndrome (ARDS) by activating caspase-1, which cleaves the precursor forms of IL-1β and IL-18 into active cytokines and induces pyroptosis by cleaving gasdermin D (GSDMD). LBH589, a pan-histone deacetylase inhibitor, exhibits promising anti-inflammatory and immunomodulatory properties. However, the protective effect and underlying mechanism of LBH589 against ARDS is still unclear.

BRISC inactivation alleviates alcohol-induced liver injury in mice.

BRCC3 isopeptidase complex (BRISC) is a JAMM subfamily deubiquitinase that has been revealed to be required for optional activation of NLRP3 inflammasome and TLR4/NF-κB signaling pathway. BRISC plays an important role in lipopolysaccharide (LPS)/D-galactosamine-induced acute liver failure, while its functional contribution to alcoholic liver disease (ALD) is still unclear. In this study, we found that the expression of BRISC components was increased in liver tissues of alcoholic hepatitis (AH) animal models and patients with AH.

MORF: Multi-view oblique random forest for hepatotoxicity prediction.

Hepatotoxicity prediction is significant in drug development, so the experts expect to get effective and reliable references. Based on the consideration that the hepatotoxicity data involve multiple types of features, this paper proposes a multi-view oblique random forest (MORF) for hepatotoxicity prediction by considering each type of feature as an independent view. The Householder transformation is employed to get the inclined cut hyperplane in each view.

Small extracellular vesicles derived from umbilical cord mesenchymal stem cells alleviate radiation-induced cardiac organoid injury.

Background: Radiation-induced heart disease (RIHD) is one of the most serious complications of radiation therapy (RT) for thoracic tumors, and new interventions are needed for its prevention and treatment. Small extracellular vesicles (sEVs) from stem cells have attracted much attention due to their ability to repair injury. However, the role of umbilical cord mesenchymal stem cell (UCMSC)-derived sEVs in protecting cardiac organoids from radiation-induced injury and the underlying mechanisms are largely unknown.

Gut microbiota's role in high-altitude cognitive impairment: the therapeutic potential of Clostridium sp. supplementation.

π-HuB: the proteomic navigator of the human body.

The human body contains trillions of cells, classified into specific cell types, with diverse morphologies and functions. In addition, cells of the same type can assume different states within an individual's body during their lifetime. Understanding the complexities of the proteome in the context of a human organism and its many potential states is a necessary requirement to understanding human biology, but these complexities can neither be predicted from the genome, nor have they been systematically measurable with available technologies.

This limits the development of mRNA vaccines based on immune-associated ferroptosis for clinical therapeutic applications. In this study, based on the rich data resources of the TCGA-LAML cohort, we analyzed the tumor mutational burden (TMB), gene mutation status, and associations between immune and ferroptosis genes to reveal the disease characteristics of AML patients.

mTORC2-driven chromatin cGAS mediates chemoresistance through epigenetic reprogramming in colorectal cancer.

Cyclic GMP-AMP synthase (cGAS), a cytosolic DNA sensor that initiates a STING-dependent innate immune response, binds tightly to chromatin, where its catalytic activity is inhibited; however, mechanisms underlying cGAS recruitment to chromatin and functions of chromatin-bound cGAS (ccGAS) remain unclear. Here we show that mTORC2-mediated phosphorylation of human cGAS serine 37 promotes its chromatin localization in colorectal cancer cells, regulating cell growth and drug resistance independently of STING. We discovered that ccGAS recruits the SWI/SNF complex at specific chromatin regions, modifying expression of genes linked to glutaminolysis and DNA replication.
