Polyproline: A Synthetic Polypeptide With Unique Properties
Poly‐L‐proline is a unique polypeptide distinguished by its well‐defined secondary structures and unusual thermal behavior. This mini review highlights recent advances in the synthesis of poly‐L‐proline by N‐carboxyanhydride (NCA) polymerization, the formation of structurally defined architectures and nanostructures, and emerging strategies that ...

Chemotherapy leverages tumor‐cell autophagy to reshape the colorectal cancer immune microenvironment. Autophagy degrades FBXW2 to promote C/EBPβ‐mediated TIMP‐2 transcription and MMP‐9 suppression, driving intra‐tumoral CD8+ T‐cell infiltration. Targeting MMP‐2/9 or restoring TIMP‐2 overcomes chemo‐resistance in autophagy‐deficient tumors. ABSTRACT The

Conversion of glutamate carbon to fatty acid carbon via citrate in rat epididymal fat pads
The incorporation of the C14 of glutamate-2-C14 and glutamate-5-C14 into fatty acids by epididymal fat pads and liver slices suggests the operation of the following metabolic pathway: α-ketoglutarate → isocitrate → cis-aconitate → citrate → acetyl CoA ...

Dual pKa Lipid Nanoparticles for Lung‐tropic mRNA Delivery and pH‐Programmed Endosomal Escape
Lipid nanoparticles’ bottleneck lies in low endosomal escape efficiency and liver‐dominant delivery after intravenous administration. To overcome these limitations, we present a stepwise pH‐programmed lipid nanoparticle system enabled by our newly synthesized ionizable lipid.
