Metabolomic interpretation of bacterial and fungal contribution to per- and polyfluoroalkyl substances interface migration in waterlogged paddy fields.

Per- and polyfluoroalkyl substances (PFAS) are widely distributed in paddy soils, and their multi-phase partitioning in soil fractions was proved to be strongly interact with soil microbial community composition and functions. Despite this, soil bacterial and fungal metabolic molecular effects on PFAS water-soil interface migration in waterlogged paddy fields still remain unclear. This study integrated soil untargeted metabolomics with microbial amplicon sequencing to elucidate soil metabolic modulations of 15 PFAS interface release.

Lympho-myeloid aggregate-infiltrating CD20 B cells display a double-negative phenotype and correlate with poor prognosis in esophageal squamous cell carcinoma.

As a disease with high incidence and mortality, research on esophageal squamous cell carcinoma (ESCC) TIL-Bs is still unclear. Thus, we aimed to investigate the prognostic value and functional involvement of TIL-Bs in ESCC.

KAT8/SIRT7-mediated Fascin-K41 acetylation/deacetylation regulates tumor metastasis in esophageal squamous cell carcinoma.

Fascin actin-bundling protein 1 (Fascin) is highly expressed in a variety of cancers, including esophageal squamous cell carcinoma (ESCC), working as an important oncogenic protein and promoting the migration and invasion of cancer cells by bundling F-actin to facilitate the formation of filopodia and invadopodia. However, it is not clear how exactly the function of Fascin is regulated by acetylation in cancer cells. Here, in ESCC cells, the histone acetyltransferase KAT8 catalyzed Fascin lysine 41 (K41) acetylation, to inhibit Fascin-mediated F-actin bundling and the formation of filopodia and invadopodia.
