Photogenerated Oxetanes as a Gateway to Uphill Cyclopropanation

Angewandte Chemie International Edition, EarlyView.
An atom‐economical route to densely functionalized cyclopropanes from furans and photochemically activated aldehydes is enabled by a unique oxetane‐to‐cyclopropane rearrangement. These cyclopropanes can be used to access complex bioactive scaffolds and serve as a platform for asymmetric cyclopropane synthesis.

Environmental Identification of Novel Enzymes for Polyurethane and Polyamide Degradation

Angewandte Chemie International Edition, EarlyView.
Heteroatom‐containing plastics such as polyurethanes and nylons are produced at scale yet remain largely unrecycled. Biocatalysts offer a promising route to depolymerization under mild conditions. Here, we present a screening platform for the discovery of novel polyurethane‐ and nylon‐degrading enzymes from environmental samples and demonstrate ...

Apolipoprotein F is reduced in humans with steatosis and controls plasma triglyceride‐rich lipoprotein metabolism

Hepatology, EarlyView., 2022
Hepatic APOF transcript levels correlate inversely with plasma TG and hepatic steatosis in humans. ApoF expression in mice promotes VLDL‐TG production and lipoprotein remnant clearance in mice. Abstract Background NAFLD affects nearly 25% of the global population. Cardiovascular disease (CVD) is the most common cause of death among patients with NAFLD,

The Effects of Enzyme Pretreatment Extraction on Lipid Recovery With Normal Phase HPLC

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT With the increasing interest in the commercialization of microalgal fermentation‐based products, sustainable and efficient oil extraction methods have been developed for manufacturing and analytical testing. Due to the variability and resilience of micro‐algae cell walls, traditional lipid extraction methods such as Folch and Bligh and Dyer ...

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

Hepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

Design‐Driven Production of Soybean Oil‐Based Structured Fats as Potential Substitutes for Palm‐Based Fats

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT This study examined whether enzymatic modification of soybean oil (SBO) can be tailored to produce trans‐free fats with physicochemical properties comparable to palm olein, stearin, or palm‐mid fractions (PMFs). US‐grown SBO was modified by lipase‐catalyzed acidolysis using palmitic acid at linearly interpolated substrate molar ratios (C16:0 ...
