Cell death regulation in Drosophila: Conservation of mechanism and unique insights [PDF]

open access: yes, 2000
Programmed cell death, or apoptosis, is a genetically encoded form of cell suicide that results in the orderly death and phagocytic removal of excess, damaged, or dangerous cells during normal development and in the adult. The cellular machinery required

The transcription factor ATF5: role in cellular differentiation, stress responses, and cancer. [PDF]

open access: yes, 2017
Activating transcription factor 5 (ATF5) is a cellular prosurvival transcription factor within the basic leucine zipper (bZip) family that is involved in cellular differentiation and promotes cellular adaptation to stress.

Convertible ROS Nanocatalyst/Eliminator for Enhancing Tumor Radio‐Immunotherapy and Relieving Radiation Enteritis

open access: yesAdvanced Science, EarlyView.
A novel Janus Ag/Ag2S nanostructure grafted with dimer PD‐L1 affibody (AMZ) is successfully developed. AMZ can be used as ROS nanocatalyst to achieve tumor radiosensitization, and it can also act as an ROS eliminator to alleviate radiation enteritis, achieving a radiotherapy strategy characterized by “toxicity reduction and efficacy enhancement ...

Astragalus polysaccharide protects human cardiac microvascular endothelial cells from hypoxia/reoxygenation injury: The role of PI3K/AKT, Bax/Bcl-2 and caspase-3.

open access: yesMolecular Medicine Reports, 2016
In the present study, the mechanisms associated with the Astragalus polysaccharide (APS)-mediated protection of human cardiac microvascular endothelial cells (HCMEC) against hypoxia/reoxygenation (HR) injury were investigated. Pretreatment of HCMECs with

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 ...

Pancreatic Cancer‐Derived Extracellular Vesicles Enriched with miR‐223‐5p Promote Skeletal Muscle Wasting Associated with Cachexia

open access: yesAdvanced Science, EarlyView.
EVs and EV‐microRNAs (miRNAs) mediate PDAC‐skeletal muscle communication. miR‐223‐5p reduces METTL14 transcription by targeting MAFA, which subsequently decreases m6A methylation in skeletal muscles, ultimately leading to muscle wasting. This study highlights the absorption of miRNA in PDAC‐derived EVs by skeletal muscles and reveals a previously ...

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.

Copper‐Based Nanotubes That Enhance Starvation Therapy Through Cuproptosis for Synergistic Cancer Treatment

open access: yesAdvanced Science, EarlyView.
We designed a copper‐based nanotube (NT) with copper ionophores to induce enhanced cuproptosis. In combination with starvation therapy, the NT significantly inhibited energy metabolism in HCC cells. Our results show that the depletion of GSH by Cu2+ intensified oxidative stress and cuproptosis, resulting in ROS generation and DLAT aggregation ...
