Caveolin-1 mitigates the advancement of metabolic dysfunction-associated steatotic liver disease by reducing endoplasmic reticulum stress and pyroptosis through the restoration of cholesterol homeostasis.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent chronic liver disease worldwide, which has the potential to advance to fibrosis. CAV1 has the effects of improving liver lipid deposition in MASLD, however, the potential mechanism is largely unknown. Here, we establish a MASLD mouse model in CAV1 knockout (KO) mice and perform transcriptome analysis on livers from mice to investigate the effects of CAV1 in MASLD progression.

Metathesis chemistry of inorganic cumulenes driven by B-O bond formation.

The reaction chemistry of an unprecedented 'inorganic cumulene' - featuring a five-atom BNBNB chain - towards C[double bond, length as m-dash]O (and related) multiple bonds is disclosed. In marked contrast to related all-carbon systems, the intrinsic polarity of the BNBNB chain (featuring electron-rich nitrogen and electron-deficient boron centres) enables metathesis chemistry with electrophilic heteroallenes such as CO and with organic carbonyl compounds. Transfer of the borylimide unit to [CO], [CS], [PP{(NDippCH)}] and [C(H)Ph] moieties generates (boryl)N[double bond, length as m-dash]C[double bond, length as m-dash]X systems (X = O, S, PP{(NDippCH)}, C(H)Ph), driven thermodynamically by B-O bond formation.

Functional evaluation and clinical classification of BRCA2 variants.

Germline BRCA2 loss-of function variants, which can be identified through clinical genetic testing, predispose to several cancers. However, variants of uncertain significance limit the clinical utility of test results. Thus, there is a need for functional characterization and clinical classification of all BRCA2 variants to facilitate the clinical management of individuals with these variants.

Investigating the origins of the mutational signatures in cancer.

Most of the risk factors associated with chronic and complex diseases, such as cancer, stem from exogenous and endogenous exposures experienced throughout an individual's life, collectively known as the exposome. These exposures can modify DNA, which can subsequently lead to the somatic mutations found in all normal and tumor tissues. Understanding the precise origins of specific somatic mutations has been challenging due to multitude of DNA adducts (i.

Deteriorated abatement of micropollutants in biological activated carbon filters with aged media: Key role of permeability.

Biological activated carbon (BAC) filtration is vital for the abatement of micropollutants in drinking water. However, limited information is available on contaminant removal in BAC filters with aged media (e.g.
