Butylparaben-Loaded Aged Polystyrene Nanoplastics Amplify Its Toxicity in via Quorum Sensing Suppression and Enhanced Microcystin-LR Release.

Aged nanoplastics are emerging pollutants in aquatic environments, but the effects of their loaded pollutants on cyanobacteria are still poorly understood. This study evaluated the adsorption of butylparaben (BP) by pristine (PS) and aged polystyrene nanoplastics (APS) and prepared BP-loaded aged PS to analyze their effects on . The results showed that APS had stronger BP adsorption and translocation capacity, with APS increasing BP adsorption by 4.

Dissolved organic matter-mediated metabolic shifts in Chlorella sorokiniana enhanced bioremediation of multi-ionic stress.

Industrial wastewater contaminated with multiple toxic ions, such as cadmium and selenite, poses a significant environmental threat. This study investigated the ability of Chlorella sorokiniana to simultaneously biomineralize cadmium and biotransform selenite in real industrial wastewater. The results demonstrated that C.

Glycerol enhanced simultaneous selenite bioremediation and astaxanthin biosynthesis in Haematococcus lacustris.

Selenium (Se) is an essential trace element with nutritional and functional significance; however, elevated concentrations of inorganic Se, particularly selenite, can cause toxicity in aquatic systems. Haematococcus lacustris, a microalga renowned for its production of astaxanthin, offers a dual approach for Se biotransformation and the synthesis of bioactive compounds. This study explores the influence of glycerol-driven biotransformation on inorganic Se uptake, selenium biotransformation, and astaxanthin accumulation.

YBX1-driven TUBB6 upregulation facilitates ocular angiogenesis via WNT3A-FZD8 pathway.

Pathological ocular neovascularization, a characteristic feature of proliferative ocular diseases, is a primary contributor to global vision impairment. The dynamics of tubulin are crucial in maintaining ocular homeostasis, closely linked to cellular proliferation and angiogenesis. Elucidating the molecular mechanisms driving this process is vital for formulating effective therapeutic strategies.

Hyperaccumulation of fucoxanthin by enhancing methylerythritol phosphate pathway in Phaeodactylum tricornutum.

The established human health benefits of carotenoids along with the contemporary consumption of natural carotenoids bring the necessity to sustainable production of carotenoids. Among, marine diatoms have emerged as the potential biological resources for carotenoid production; however, their relatively lower yield in native strains provides the impetus to genetically improve the diatoms to cope with the burgeoning demand. In this study, we genetically improved the diatom Phaeodactylum tricornutum by overexpressing key carotenogenic genes involved in methylerythritol phosphate (MEP) pathway.
