Materials‐Guided Gene‐Ionizable Lipid Nanoparticles to Reverse Iron‐Associated Immune Resistance in Renal Cancer

Advanced Science, EarlyView.
ABSTRACT Iron overload is a common metabolic disturbance in cancer and contributes to poor outcomes in renal cell carcinoma (RCC), yet its effects on the tumour immune microenvironment remain unclear. Here we identify a previously unrecognized immunosuppressive axis in which iron overload downregulates the palmitoyltransferase ZDHHC12 in CD8+ T cells ...

Transcriptional and genetic alterations of cuproptosis-related genes correlated to malignancy and immune-infiltrate of esophageal carcinoma

Cell Death Discovery, 2022
Esophageal carcinoma (ESCA) is a common type of cancer with high mortality. Cuproptosis is a new type of cell death and is characterized by the dependence on mitochondrial respiration and protein lipoylation.

Astrocytic FDX1 Contributes to Copper Dyshomeostasis‐associated Synaptic Dysfunction in Depression and Is Modulated by Exercise

Advanced Science, EarlyView.
Chronic stress disrupts copper homeostasis and promotes copper accumulation in the prelimbic cortex, leading to astrocytic FDX1 upregulation. Elevated astrocytic FDX1 impairs calcium signaling, induces structural atrophy, and disrupts synaptic function, contributing to depressive‐like behaviors. Physical exercise reverses these alterations by restoring

Solanum lycopersicum (tomato) possesses mitochondrial and plastidial lipoyl synthases capable of increasing lipoylation levels when expressed in bacteria [PDF]

, 2020
Lipoic acid (LA) and its reduced form (dihydrolipoic acid, DHLA) have unique antioxidant properties among such molecules. Moreover, after a process termed lipoylation, LA is an essential prosthetic group covalently-attached to several key multi-subunit

A Case of Multiple Mitochondrial Dysfunctions Syndrome 1 and Review of the Literature

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Multiple mitochondrial dysfunctions syndrome 1 (MMDS1, MIM #605711) due to NFU1 gene defects is an ultra‐rare autosomal recessive inborn error of metabolism associated with reduced function of NFU1 iron–sulfur cluster (ISC) scaffold protein.

Knockout studies reveal an important role of Plasmodium lipoic acid protein ligase A1 for asexual blood stage parasite survival. [PDF]

PLoS ONE, 2009
Lipoic acid (LA) is a dithiol-containing cofactor that is essential for the function of alpha-keto acid dehydrogenase complexes. LA acts as a reversible acyl group acceptor and 'swinging arm' during acyl-coenzyme A formation.

Enhanced strategies for cuproptosis‐like death in bacterial infection treatment

BMEMat, EarlyView.
This review summarizes and examines the molecular mechanisms underlying cuproptosis‐like death. Furthermore, multi‐strategy efficacy enhancement and potential enhancement approaches are analyzed. Abstract Copper, a classical antibacterial metal, has long been of interest and widely used in medical and public health applications.

Post-translational modification in the archaea: structural characterization of multi-enzyme complex lipoylation [PDF]

, 2013
Lipoylation, the covalent attachment of lipoic acid to 2-oxoacid dehydrogenase multi-enzyme complexes, is essential for metabolism in aerobic bacteria and eukarya.

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

Cell Proliferation, EarlyView.
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.
