β‐Elemene Rescues Radiation‐Induced Enteritis by Orchestrating a Host‐Microbiome Circuit That Fuels Epigenetic DNA Repair

open access: yesAdvanced Science, EarlyView.
This study elucidates that β‐elemene promotes cellular uptake of L. gasseri‐derived lactate by enhancing the membrane translocation of MCT1 in a CD147‐dependent manner. Intracellular lactate, through the lactylation of RBBP4 at the K26 site, recruits EP300 to the promoter regions of downstream genes (POLD1/POLD3), catalyzing H3K27ac modification.

The Dimeric Caspase-9 Exhibits a Much Lower Activity Than the Apaf-1-Activated WT Caspase-9

open access: yes, 2013
(A) Using fluorescent substrate LEHD-AFC, the catalytic activity of the Apaf-1-activated WT caspase-9 was approximately 35-fold greater than that of the dimeric caspase-9.

Light‐Activatable Nitric Oxide Release via Intramolecular Electron Transfer for Tumor Pyroptosis Induction

open access: yesAdvanced Science, EarlyView.
This work proposes a novel strategy to fabricate unimolecular pyroptosis photoinitiators activated by deep‐red light at low light doses. It relies on a photosensitization mechanism to trigger nitric oxide (NO) release from benzisothiadiazole‐based N‐nitrosanilines without modification of nitro moieties, thereby boosting pyroptosis‐mediated ...

Beta-mangostin from activates the intrinsic apoptosis pathway through reactive oxygen species with downregulation of the HSP70 gene in the HL60 cells associated with a G/G cell-cycle arrest

open access: yesTumor Biology, 2017
Xanthones are phytochemical compounds found in a number of fruits and vegetables. Characteristically, they are noted to be made of diverse properties based on their biological, biochemical, and pharmacological actions.

Enhancing Maturation of Human Neuromuscular Organoids via Electrical Stimulation

open access: yesAdvanced Science, EarlyView.
A framework for on‐demand and non‐invasive exposure of human neuromuscular organoids (NMOs) to electrical stimuli is established to promote their maturation. The robustness and effectiveness of different stimulation regimes are evaluated via thorough characterization of organoid tissue structure and contraction capacity. Chronic electrical stimulation,

Harnessing MDM2‐Mediated Targeted Degradation of Transcriptional and Epigenetic Machinery to Disrupt Oncogenic Addictions in Pediatric Sarcoma

open access: yesAdvanced Science, EarlyView.
MDM2 dependency in pediatric sarcomas is driven by a novel p53‐independent oncogenic cistrome alongside canonical p53 pathway suppression. This study introduces MDM2‐recruiting transcriptional and epigenetic machinery degraders (MDM2‐TEMADs) as a novel precision oncology modality.

Interactions in the Active Site Loops are Important for Maintaining the Active Site Environment of (Pro)caspase-3

open access: yes, 2004
Apoptosis is obligatory to development and in maintaining the vital balance between cell growth and death. Commitment to apoptosis involves a proteolytic cascade by a family of cysteine proteases named caspases.

SA and SB abolished the UVB-mediated cleavage of caspase-3, caspase-8 and caspase-9 levels in HaCaT cells.

open access: yes, 2015
HaCaT cells were treated with 100 μM SA or SB for 24 h, followed by exposure to 30 mJ/cm2 of UVB. After 24 h, the cells were performed. (A) The expression of caspase-3, cleaved caspase-3, caspase-8, cleaved caspase-8, caspase-9 and cleaved caspase-9 were

BIN1 and ALDH1B1 Deficiency in Colonic Smooth Muscle Drives Mitochondrial Dysfunction and Fibrosis in Slow‐Transit Constipation

open access: yesAdvanced Science, EarlyView.
Slow‐transit constipation (STC) is a disabling motility disorder with unclear smooth‐muscle mechanisms. Spatial proteomic analysis of STC patient colon reveals both the central pathogenic role of smooth muscle cells (SMCs) in STC and novel regulators of intestinal motility, BIN1 and ALDH1B1.
