Cuproptosis and Mitophagy Mediated by the THUMPD1/IGF2R‐Dependent Suppression of AKT and Activation of AMPK Signaling Suppress Lung Adenocarcinoma Progression

Advanced Science, EarlyView.
THUMPD1 drives a tumor‐suppressive signaling cascade in lung adenocarcinoma by promoting IGF2R expression. IGF2R associates with PPP2R1A to suppress AKT and activate AMPK, leading to SLC31A1 upregulation and copper accumulation. Elevated copper disrupts mitochondrial metabolism and induces excessive mitophagy, thereby restraining tumor growth and ...

GRASP55 facilitates autophagosome maturation under glucose deprivation

Molecular & Cellular Oncology, 2018
Under growth condition, the Golgi reassembly-stacking protein of 55 kDa (GRASP55)/GORASP2 serves as the “glue” to hold adjacent Golgi cisternae into stacks by forming trans-oligomers. Upon glucose starvation, GRASP55 is de-O-GlcNAcylated and functions as

The mitochondrial protease HtrA2 restricts the NLRP3 and AIM2 inflammasomes. [PDF]

, 2018
Activation of the inflammasome pathway is crucial for effective intracellular host defense. The mitochondrial network plays an important role in inflammasome regulation but the mechanisms linking mitochondrial homeostasis to attenuation of inflammasome ...

Dynamic Shifts in ER–Plasma Membrane Junctions Signaling Define Pro‐Metastatic N‐Glycosylation and Predict Prostate Cancer Progression

Advanced Science, EarlyView.
Prostate cancer remains a leading cause of male cancer death, yet screening cannot reliably identify aggressive disease, underscoring the need for tissue biomarkers. It is shown that primary tumors increase ER–plasma membrane junction signaling via STIM1/ORP5, whereas metastasis features their loss, Golgi dispersal, and rapid conversion of high‐mannose

Fluorescence Microscopy Analysis of Drug Effect on Autophagosome Formation

Bio-Protocol, 2014
The autophagy protein, LC3 represents a reliable characteristic marker for autophagosomal structures. The initial LC3 is processed by the cysteine protease autophagy-related gene 4 (Atg4) at its C terminus in order to create LC3-I generally localized in ...

ESCRT‐Mimetic Nanodegrader Targets STING for Anti‐Inflammatory Therapy

Advanced Science, EarlyView.
A nanoplatform‐enabled targeted protein degradation strategy is presented to regulate aberrant STING signaling. STING‐ATTEC induces selective autophagic degradation of STING via formation of a STING–ATTEC–LC3 ternary complex, while the cationic FA‐LNP+ system enhances LC3 generation and targeted delivery. Together, this synergistic approach efficiently

DRAM-3 modulates autophagy and promotes cell survival in the absence of glucose [PDF]

, 2015
Macroautophagy is a membrane-trafficking process that delivers cytoplasmic constituents to lysosomes for degradation. The process operates under basal conditions as a mechanism to turnover damaged or misfolded proteins and organelles. As a result, it has

Targeting Endogenous Lipophagy: A Novel Strategy to Enhance MSC Osteogenesis and Mineralization for Senile Osteoporosis Therapy

Advanced Science, EarlyView.
Schematic representation of the role of lipophagy in bone mesenchymal stem cells(MSCs). In healthy MSCs, functional lipophagy efficiently degrades lipid droplets to support oxidative phosphorylation and cellular energy production, thereby facilitating osteogenic differentiation and matrix mineralization.

Receptor‐mediated clustering of FIP200 bypasses the role of LC3 lipidation in autophagy

EMBO Journal, 2020
Autophagosome formation requires multiple autophagy‐related (ATG) factors. However, we find that a subset of autophagy substrates remains robustly targeted to the lysosome in the absence of several core ATGs, including the LC3 lipidation machinery.
