Endogenous glucagon-like peptide 1 controls endocrine pancreatic secretion and antro-pyloro-duodenal motility in humans
The inhibition of mTORC1 signaling by cystine starvation demonstrated that regulation of this pathway is not limited to essential amino acids 9,10,11,12 , but is also regulated by cysteine availability (Fig
Nanoparticle-based systems, such as recombinant human ferritin (rHF), represent a significant advance by functioning as scavengers for multiple types of ROS and inhibiting parallel cell death pathways (Qi, 2024)
