Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Biochar and urea enhance phytoremediation of PAH-Pb co-contaminated karst soil: bacterial and metabolic insights

open access: yesFrontiers in Microbiology
The remediation of polycyclic aromatic hydrocarbon and lead co-contaminated soils in karst regions remains challenging because of strong soil buffering capacity, complex metal speciation, and the distinct transformation mechanisms of organic pollutants ...

Contaminants of emerging concern and aquatic organisms: the need to consider hormetic responses in effect evaluations

open access: yes, 2021
Contaminants of emerging concern are widespread in the world’s waters, raising concerns regarding their effects on living organisms. To evaluate the effects of and predict risks associated with such chemicals, dose-response studies are needed, while the ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

open access: yesFEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Synthesis of borocarbonitride nanosheets from biomass for enhanced charge separation and hydrogen production

open access: yesScientific Reports
Borocarbonitride (BCN) materials have shown significant potential as photocatalysts for hydrogen production. However, traditional bulk BCN exhibits only moderate photocatalytic activity.

Occurrence, Sources, and Prioritization of Per- and Polyfluoroalkyl Substances (PFASs) in Drinking Water from Yangtze River Delta, China: Focusing on Emerging PFASs

open access: yesMolecules
As regulations ban legacy PFASs, many emerging PFASs are being developed, leading to their release into the aquatic environment and drinking water. However, research studies on these emerging PFASs in drinking water are limited, and current standards ...

Modelling ecological risks of antiretroviral drugs in the environment

open access: yesEnvironmental Chemistry and Ecotoxicology, 2023
The success of the antiretroviral therapy (ART) programme to manage HIV/AIDS in Sub-Saharan Africa (SSA) has inadvertently led to the release of antiretroviral (ARVs) into the environment.
