Unraveling Tissue‐Specific Fatty Acid Biosynthesis and Inter‐Tissue Crosstalk in Mice through Stable‐Isotope Tracing Metabolomics

open access: yesAdvanced Science, EarlyView.
Biosynthesis rates of 13 FFAs are quantitatively calculated in 15 tissues from glucose and an analytical framework to quantitatively calculate inter‐tissue communications of fatty acids between the liver and other tissues is developed. Moreover, the approach is extended to aging condition and a system‐wide decline of fatty acid synthesis in peripheral ...

Structural Basis of Sequential Enantioselective Epoxidation by a Flavin‐Dependent Monooxygenase in Lasalocid A Biosynthesis

open access: yesAngewandte Chemie, EarlyView.
Lsd18 is a flavin‐dependent monooxygenase from Streptomyces lasalocidi that performs two enantioselective epoxidations during lasalocid A biosynthesis. X‐ray crystal structures of Lsd18 bound to a substrate and product analogue illuminate how this enzyme performs multiple epoxidations on the same substrate molecule and how it controls stereoselectivity.

Bioinspired Claw‐Engaged Adhesive Microparticles Armed with γGC Alleviate Ulcerative Colitis via Targeted Suppression of Macrophage Ferroptosis

open access: yesAdvanced Science, EarlyView.
γGC deficiency in ulcerative colitis drives macrophage ferroptosis‐mediated inflammation. Claw‐engaged microparticles armed with γGC (γGC‐MPs) enhance lesion targeting, promoting localized γGC release and tissue uptake. On the cover, Monkey King (Macrophages) was bound by the Immortal‐Binding Rope and subsequently sealed beneath the Five‐Fingered ...

Development of an Organoautocatalyzed Double σ‐Bond C(sp2)‐N Transamination Metathesis Reaction

open access: yesAngewandte Chemie, EarlyView.
Organoautocatalyzed transamination metathesis of cyclic tertiary amines is disclosed as a high‐yielding, scalable reaction that proceeds under mild, catalyst‐free conditions. It operates via a multi‐step domino reaction mechanism, where an in situ‐formed pyrrolidinium salt functions as a HBD organoautocatalyst.

Efficacy of coenzyme Q10 in patients with cardiac failure: a meta-analysis of clinical trials

open access: yesBMC Cardiovascular Disorders, 2017
Background The therapeutic efficacy of coenzyme Q10 on patients with cardiac failure remains controversial. We pooled previous clinical studies to re-evaluate the efficacy of coenzyme Q10 in patients with cardiac failure.

Refinements of the inequalities between Neuman-Sandor, arithmetic, contra-harmonic and quadratic means [PDF]

open access: yesarXiv, 2012
In this paper, we prove that the inequalities $\alpha [1/3 Q(a,b)+2/3 A(a,b)]+(1-\alpha)Q^{1/3}(a,b)A^{2/3}(a,b)0$ with $

A Feedback Loop Between Fatty Acid Metabolism and Epigenetics in Clear Cell Renal Carcinoma

open access: yesAdvanced Science, EarlyView.
The current study has profiled the landscape of active enhancers in ccRCC and identified FABP5 as an oncogene. FABP5 is essential for the lipid droplet formation driven by HIFs and critical for H3K27ac and enhancer activity. The study has discovered the function of a feedback loop between epigenetics and lipid metabolism regulated by FABP5 in ccRCC ...
