At junctions and other structures, such as pseudoknots and kissing loops, adjacent helices stack on one another, and these coaxial stacks play a major role in dictating the overall architectural form of an RNA molecule. In addition to RNA junction topology, a second determinant for RNA tertiary ...

Specifically, Semaglutide (SEMA), a glucagon-like peptide-1 receptor agonist (GLP-1 RA) molecule approved for the treatment of both type 2 diabetes (T2D) and obesity associated with significant improvement in metabolic syndrome parameters [43, 44], was tested since fasting HFD mice showed lower...
4d). This observation strongly suggests a single adduct event can shift the RNA molecule to LP, and accumulation of multiple adducts per mRNA molecule further drives increases in retention time. The binary system was then used to study contributions of the mRNA molecule to adduct formation. A ...
“The Catalyst” looks at RNA’s role in life’s origins as well as its medical uses The Catalyst. Thomas Cech. W.W. Norton; 304 pages; $28.99 and £23.99 What you see depends on how you look. For years students of cell biology were taught that...
Notably, the increase in TREM2 was reversed by a small-molecule TGF-β inhibitor, confirming the role of TGF-β1 in the induction of TREM2+ macrophages. Metabolic reprogramming is a crucial factor in HCC development, and the activation of glycolysis is a common feature in various cancers. ...
