Synergistic Effects of Polyphenols and Methylxanthines with Leucine on AMPK/Sirtuin-Mediated Metabolism in Muscle Cells and Adipocytes

open access: yesPLoS ONE, 2014
The AMPK-Sirt1 pathway is an important regulator of energy metabolism and therefore a potential target for prevention and therapy of metabolic diseases.

Correlation Between Fecal Microbiota and Corticosteroid Responsiveness in Primary Immune Thrombocytopenia: an Exploratory Study

open access: yesAdvanced Science, EarlyView.
This study uses gut microbiome data to predict corticosteroid response in patients with immune thrombocytopenia (ITP). Fecal samples from 212 patients with ITP are sequenced. Six machine‐learning algorithms are used to train predictive models. The support vector machine‐based model integrated clinical data and selected microbial species, diversities ...

Leucine Aminopeptidase in Candida Albicans

open access: yesJournal of Investigative Dermatology, 1962
Since the late 19th century, there have been numerous publications on proteolytic enzymes in dermatophytes (for literature see 1-5). Bodin (1907), Mallinckrodt-Haupt (1928), and Tate (1929) stated that active proteolytic enzymes (e.g. trypsin, casease, renin, gelatinase (1, 2), or enzymes with activity very similar to trypsin (3)) are present in the ...

Orally Administered Functional Polyphenol‐Nanozyme‐Armored Probiotics for Enhanced Amelioration of Intestinal Inflammation and Microbiota Dysbiosis

open access: yesAdvanced Science, EarlyView.
This study presents a novel polyphenol‐nanozyme‐armored probiotic system (ECA@EcN) for enhanced treatment of inflammatory bowel disease (IBD). By integrating chitosan‐modified epigallocatechin gallate (EGCG‐CS) with gold nanozymes, the system effectively scavenges ROS, improves probiotic viability, and restores gut microbiota balance.

Genome and transcriptome analysis of Bacillus velezensis BS‐37, an efficient surfactin producer from glycerol, in response to d‐/l‐leucine

open access: yesMicrobiologyOpen, 2019
Surfactin is one of the most widely studied biosurfactants due to its many potential applications in different fields. In the present study, Bacillus velezensis BS‐37, initially identified as a strain of Bacillus subtilis, was used to efficiently produce

Differential regulation of protein synthesis in skeletal muscle and liver of neonatal pigs by leucine through an mTORC1-dependent pathway

open access: yesJournal of Animal Science and Biotechnology, 2012
Neonatal growth is characterized by a high protein synthesis rate that is largely due to an enhanced sensitivity to the postprandial rise in insulin and amino acids, especially leucine. The mechanism of leucine's action in vivo is not well understood. In

The Novel Dual GIP and GLP‐1 Receptor Agonist Tirzepatide Attenuates Colon Cancer Development by Regulating Glucose Metabolism

open access: yesAdvanced Science, EarlyView.
Tirzepatide, a dual GIP/GLP‐1 receptor agonist for diabetes, suppresses colorectal cancer growth by targeting glucose metabolism. It inhibits cancer cell proliferation, promotes apoptosis, and induces tumor regression. It reduces glucose uptake and destabilizes HIF‐1α for degradation to downregulate PFKFB3/PFK‐1 enzymes, thus contributing to the ...

CPL‐Diff: A Diffusion Model for De Novo Design of Functional Peptide Sequences with Fixed Length

open access: yesAdvanced Science, EarlyView.
This study presents a diffusion model for generating functional peptide sequence lengths using mask control. The model can generate antimicrobial, antifungal, and antiviral peptides with specific lengths on demand. The model learns the structure of peptides better and generates peptides with better physicochemical properties, and the model has good ...

The Evolution of tRNA-Leu Genes in Animal Mitochondrial Genomes [PDF]

open access: yesarXiv, 2003
Animal mitochondrial genomes usually have two transfer RNAs for Leucine: one, with anticodon UAG, translates the four-codon family CUN, whilst the other, with anticodon UAA, translates the two-codon family UUR. These two genes must differ at the third anticodon position, but in some species the genes differ at many additional sites, indicating that ...
