Recently, Pham et al. used an array of model systems to uncover a role for the enzyme methionine adenosyltransferase (MAT)-1A, which is mainly expressed in liver, in both sensing formaldehyde and regulating transcriptional responses that protect against it. This provides a new lens for understanding the effects of formaldehyde on gene regulation.

As a group I carcinogen, environmental exposures to formaldehyde (FA) have been associated with various types of malignancies. However, exact mechanisms of FA-triggered carcinogenesis are still not clear. Lactylation is recently identified as a post-translational modification driven by overproduced lactic acid (LA) that regulates protein activities in different cellular processes.

While FA has been implicated in various cancers, its genotoxic effects, including DNA damage and DNA-protein crosslinking, have proven insufficient to fully explain its role in carcinogenesis, suggesting the involvement of epigenetic mechanisms. Histone post-translational modifications (PTMs) on H3 and H4, critical for regulating gene expression, may contribute to FA-induced pathogenesis as lysine and arginine residues serve as targets for FA-protein adduct formation.

Monodisperse carbon materials have attracted increasing attention in the fields of catalysis, adsorption, and energy storage. However, the preparation of monodisperse microstructure-controlled carbon spheres still faces tremendous challenges due to the complexity of involved polymerization/carbonization processes and the difficulty of controlling high monodispersity and regulating microstructures, which are vital for ensuring a uniform packing, determining consistent physical and chemical properties and targeting applications. Here, we report an approach to address these issues by co-doping nickel and nitrogen into an aminophenol-formaldehyde resin (APFR) polymer framework.

Iron-based inorganic-organic hybrid Fenton catalysts, which recently emerged, are recognized as among the novel materials for the deep mineralization of inert pollutants for environmental remediation in photo-assisted Fenton-like reactions, which are one of the typical advanced oxidation processes (AOPs). In this work, magnetically recycling catalysts of resorcinol-formaldehyde resin/magnetite (RF/FeO) core-shell microspheres were rationally designed by tuning the core-shell sequence for visible-light-driven reagent-free Fenton-like oxidation of organic dyes. It is noted that the impact of the core-shell sequence on the nano-structure and reactivity of such spherical catalysts is rarely reported.

Utilizing polymeric catalysts to generate hydrogen peroxide (HO) via photocatalysis for various industrial applications is a promising avenue, but the application potential is constrained by their low charge separation efficiency and the capacity for oxygen adsorption and activation. Herein, a polymeric catalyst (NiRF) modified with Ni metal sites on resorcinol-formaldehyde (RF) resin is presented, which can efficiently produce HO through photocatalysis in pure water. The optimal NiRF-5 exhibits an impressive HO generation rate of up to 31.
