Targeted Penetrating Motif Engineering of BH3 Mimetic: Harnessing Non‐Canonical Amino Acids for Coinhibition of MCL‐1 and BCL‐xL in Acute Myeloid Leukemia

open access: yesAdvanced Science, EarlyView.
A structure‐guided peptide derived from a non‐canonical amino acid library simultaneously targets MCL‐1 and BCL‐xL to overcome apoptotic resistance in acute myeloid leukemia. Fused with a CXCR4‐binding motif, the engineered peptide exhibits selective intracellular delivery and potent in vivo efficacy, offering a promising therapeutic strategy against ...

A Dual‐Targeting T6SS DNase Drives Bacterial Antagonism and Eukaryotic Apoptosis via the cGAS‐STING‐TNF Axis

open access: yesAdvanced Science, EarlyView.
The bacterial Type VI secretion system (T6SS) emerges as a sophisticated virulence mechanism, leveraging the dual‐function effector TkeA from Yersinia pseudotuberculosis. TkeA concurrently damages rival bacteria and host cell DNA, triggering the host's cGAS‐STING‐TNF pathway and inducing apoptosis.

Multi‐Omics and ‐Organ Insights into Energy Metabolic Adaptations in Early Sepsis Onset

open access: yesAdvanced Science, EarlyView.
This study shows that patients at risk of sepsis have a distinct metabolite and lipid signature, including serine and aminoadipic acid, in their serum before clinical diagnosis. A mouse model of sepsis with a compatible serum signature reveals underlying metabolic changes, including mitochondrial adaptation, altered serine‐dependent purine metabolism ...

Oxidative Rearrangements of the Alkaloid Intermediate Geissoschizine

open access: yesAngewandte Chemie, EarlyView.
19E‐geissoschizine is a key precursor in the biosynthesis of monoterpene indole alkaloids such as strychnine, ibogaine, and vinblastine. Using enzymatic assays and gene silencing, three CYPs were identified from C. roseus that oxidize this compound to four alkaloid scaffolds: strychnos, sarpagan, akuammiline, and mavacurane. Mutational analysis reveals

PHOSPHO1 Suppresses Ferroptosis in Retinal Pigment Epithelial Cells by Reducing the Levels of Phosphatidylethanolamine Molecular Species

open access: yesAdvanced Science, EarlyView.
Iron‐induced lipid peroxidation of phosphatidylethanolamine (PE) species is the key driver of ferroptosis. The authors discovered that PHOSPHO1 lowers the level of PE in retinal pigment epithelial cells thus reducing the formation of lipid peroxides. Lowering PE levels can also prevent the creation of autolysosomes, reduce the production of free iron ...
