Reciprocal control of viral infection and phosphoinositide dynamics
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

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 ...

Global, site-specific analysis of neuronal protein S-acylation
Protein S-acylation (palmitoylation) is a reversible lipid modification that is an important regulator of dynamic membrane-protein interactions. Proteomic approaches have uncovered many putative palmitoylated proteins however, methods for comprehensive ...

ABSTRACT Doxorubicin‐induced cardiomyopathy (DIC) remains a dose‐limiting clinical challenge. This study reveals that cardiac vascular endothelial cells (CVECs) act as initial sensors of doxorubicin cardiotoxicity: circulating doxorubicin activates the cGAS‑STING pathway in CVECs, triggering NLRP3 inflammasome‑mediated pyroptosis and release of ...

S-palmitoylation of Rotavirus NSP4
Rotavirus is the primary cause of gastroenteritis in children. The clinical symptoms of the disease include fever, vomiting and diarrhoea, which can be fatal due to excessive fluid loss.

Radiotherapy triggers LTβR N‐glycosylation, enhancing its overall protein stability and nuclear retention. This accumulation drives TRIM28‐mediated PCBP2 SUMOylation, suppressing pyroptosis and conferring gastric cancer radioresistance. Therapeutically, a targeted nanoplatform (cRGD‐Lipo@EMD) effectively disrupts this regulatory axis, offering a highly

S-palmitoylation and depalmitoylation at the interface of animal virus-host interactions
Reversible protein S-palmitoylation, mediated by protein acyl transferases (PATs) and depalmitoylases, is essential for regulating numerous biological processes, including subcellular localization, protein stability, enzymatic activity, and protein ...

UBE2O targets CDKL1 for the degradation to upregulate PD‐L1 expression and promotes resistance to radioimmunotherapy in lung cancer, supporting the potential of targeting UBE2O as a promising therapeutic strategy. ABSTRACT Resistance to radioimmunotherapy is one of the primary causes of treatment failure in lung cancer patients; however, the underlying

Nutrient-dependent changes of protein palmitoylation: impact on nuclear enzymes and regulation of gene expression. [PDF]
Diet is the main environmental stimulus chronically impinging on the organism throughout the entire life. Nutrients impact cells via a plethora of mechanisms including the regulation of both protein post-translational modifications and gene expression ...
