Subjective Cognitive Concerns and Cognitive Trajectories in Parkinson's Disease: Biomarker Impact

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the relationship of subjective cognitive concerns (SCC) with biomarkers of Alzheimer's disease (AD), neurodegeneration, and Parkinson's disease (PD) and domain‐specific cognitive trajectories among cognitively unimpaired persons with de novo PD. Method Cognitively unimpaired participants with SCC (n = 294) and without SCC (

Chemical Strategies for Multistimuli Responsive Dynamic Covalent Materials in Regenerative Medicine

open access: yesAdvanced Healthcare Materials, EarlyView.
Multistimuli responsive dynamic covalent materials integrate reversible chemistry with the complex chemical, mechanical, and biochemical cues of regenerative environments. This review highlights chemical strategies based on orthogonal dynamic bonds, multicomponent networks, and hierarchical architectures to regulate mechanics, degradation, and ...

Interactive effects of threonine levels and protein source on growth performance and carcass traits, gut morphology, ileal digestibility of protein and amino acids, and immunity in broilers

open access: yesPoultry Science, 2020
: An experiment was executed to test the hypothesis that supplementation of dietary threonine (d-Thr), above NRC recommendation to diets containing poorly digestible protein source (PS) may compensate its detrimental effects on overall performance of ...

Phosphorylated STYK1 Promotes Gemcitabine Resistance via Autophagy‐Mediated Cancer Stemness in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
Gemcitabine resistance remains a major challenge in pancreatic ductal adenocarcinoma. This study identifies STYK1 as a key mediator of chemoresistance through autophagy‐dependent maintenance of cancer stemness. Gemcitabine‐activated AMPK phosphorylates STYK1 at Ser91 and Ser304, enhancing autophagy and stemness.

Role of L-Threonine Deaminase and L-Threonine 3-Dehydrogenase in the Utilization of L-Threonine by Pseudomonas aeruginosa

open access: yesMicrobiology, 1980
Mutants of Pseudomonas aeruginosa PAC1 which could grow on L-threonine were isolated. These mutants, like the parent strain, synthesized a biosynthetic threonine deaminase, but its apparent Km value for threonine was higher than that of the enzyme from strain PAC1. These mutants also synthesized an inducible NAD-dependent threonine dehydrogenase, which

UDP‐Glucose‐6‐Dehydrogenase Mediated O‐GlcNAcylation of Tight Junction Protein 1 Suppresses Metastasis in Renal Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
Our research unveiled a regulatory paradigm wherein TRIM25 orchestrates the ubiquitin‐mediated degradation of UGDH. UGDH modulates the protein stability of TJP1 by regulating O‐GlcNAcylation levels, effectively impeding the metastasis of ccRCC. Our insights elevate UGDH to a pivotal biomarker and tumor suppressor, marking the first demonstration that ...

Single‐Cell Transcriptomic Analysis of Tumor Heterogeneity and the Microenvironment in Pseudomyxoma Peritonei

open access: yesAdvanced Science, EarlyView.
This study presents a single‐cell atlas of pseudomyxoma peritonei spanning primary and paired metastatic lesions. Distinct epithelial substates, stromal remodeling, immune exclusion, lipid metabolic reprogramming, and a candidate angiogenic network were identified in metastatic lesions.

Effects of different dietary threonine and glycine supplies in broilers fed low-protein diets

open access: yesFrontiers in Veterinary Science
The reduction of crude protein (CP) content of broiler diets with balanced amino acid supply can increase the nitrogen (N) utilization efficiency and reduce ammonia emission, the risk of many health problems in birds.
