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

Advanced Science, Volume 13, Issue 42, 28 July 2026.
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 ...

The Multifaceted Role of Pyroptosis: Molecular Mechanisms, Crosstalk with Other Cell Death Pathways, and Therapeutic Implications

MedComm, Volume 7, Issue 7, July 2026.
Pyroptosis maintains immune homeostasis by eliminating damaged or infected cells, but its dysregulation promotes inflammation and cancer progression. The diagram illustrates key activation pathways, links with other programmed cell deaths, and cancer‐specific effects, enhancing its dual protective and pathogenic roles.

From Cold to Hot: Nanozyme‐Based Strategies for Reprogramming the Tumour Immunoenvironment

Cell Proliferation, Volume 59, Issue 7, July 2026.
Nanozymes, with multi‐enzyme catalytic activities, reprogram the immunosuppressive tumour microenvironment by inducing immunogenic cell death, relieving hypoxia, and depleting antioxidants, effectively converting immunologically “cold” tumours into “hot” ones to boost cancer immunotherapy efficacy.

A script to highlight hydrophobicity and charge on protein surfaces [PDF]

, 2015
The composition of protein surfaces determines both affinity and specificity of protein-protein interactions. Matching of hydrophobic contacts and charged groups on both sites of the interface are crucial to ensure specificity.

Mechanism-Driven Metabolic Engineering for Bio-Based Production of Free R-Lipoic Acid in Saccharomyces cerevisiae Mitochondria

Frontiers in Bioengineering and Biotechnology, 2020
Lipoic acid is a valuable organosulfur compound used as an antioxidant for dietary supplementation, and potentially anti-diabetic and anti-cancer. Currently, lipoic acid is obtained mainly through chemical synthesis, which requires toxic reagents and ...

Light Activated Induction of Cuproptosis in Resistant Cancer Cells Using Polymeric BODIPY Nanoparticles for Photoactivated Chemotherapy

Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
This article presents a photo‐responsive nanoparticle platform that precisely triggers copper‐dependent cuproptotic cell death in (drug‐resistant) cancer cells. The system remains stable and inactive in the dark but releases cytotoxic species upon red‐light irradiation, achieving potent activity in drug‐resistant breast cancer cells.

cDNA sequence, in vitro synthesis, and intramitochondrial lipoylation of H-protein of the glycine cleavage system.

Journal of Biological Chemistry, 1990
H-protein is a component of the glycine cleavage system loosely associated with the mitochondrial inner membrane and has lipoic acid as a prosthetic group. cDNA clones encoding H-protein were isolated from a bovine liver cDNA library with an oligonucleotide probe from the amino acid sequence of the NH2-terminal region. DNA sequence analysis and deduced
