Serine- and Threonine/Valine-Dependent Activation of PDK and Tor Orthologs Converge on Sch9 to Promote Aging

PLoS Genetics, 2014
Dietary restriction extends longevity in organisms ranging from bacteria to mice and protects primates from a variety of diseases, but the contribution of each dietary component to aging is poorly understood. Here we demonstrate that glucose and specific

Antibody‐Programmable Bimetallic Nanozymes for Transcriptional Blockade Therapy in HER2/ER‐Positive Breast Cancer

Advanced Functional Materials, EarlyView.
Zr‐Fe MOF@Ribociclib@Herceptin (ZFRH) efficiently targets/kills Human Epidermal Growth Factor Receptor 2/Estrogen Receptor‐positive (HER2/ER+) breast cancer cells. It combats tumors by: 1) Elevating ROS, altering redox balance; 2) Inhibiting transcription; 3) Inducing pyroptosis.

Aptamer Functionalized Hydrogel Dressings for Post‐Surgery Tumor Recurrence Inhibition and Tissue Reconstruction

Advanced Functional Materials, EarlyView.
Post‐surgical tumor therapy struggles with recurrence and inefficient healing. Anti‐tumor DNA aptamer functionalized gelatin hydrogels, Apt‐GelMA, simultaneously address both issues by suppressing tumor regrowth via targeted tumor cell inhibition and enhancing wound healing through improved cell adhesion and migration. Their biocompatibility, stability,

Effect of threonine level in a high-protein diet on the growth performance and carcass characteristics of 50- to 91-day-old slow-growing indigenous male Boschveld chickens

Frontiers in Animal Science
Broiler chickens are economically, nutritionally, and culturally very important. An experiment was conducted to determine the effect of dietary threonine level on the growth performance of slow-growing 50- to 91-day-old male Boschveld chickens.
