An Obese Genotype Affects the Sphingolipid Signaling Pathway [PDF]

open access: yes, 2008
Sphingolipids are important signaling molecules regulating cell growth, cell death and differentiation, thus making them important molecules in determining the fate of a cell and in the pathogenesis of chronic illnesses.

The Cancer Cell Metabolic Reprogramming Remodels the Tumor Microenvironment: Molecular Mechanisms and Therapeutic Strategies

open access: yesAdvanced Science, EarlyView.
This review elucidates how cancer cell metabolic reprogramming—across glucose, lipid, amino acid, and nucleotide pathways—remodels the tumor microenvironment to suppress anti‐tumor immunity and promote immune escape. Targeting these metabolic axes offers promising strategies to overcome immunotherapy resistance and enhance cancer treatment.

Orm2 promotes nitrogen-induced sphingolipid production and endocytosis via Orm1 phosphorylation

open access: yesJournal of Lipid Research
The Orm family of proteins inhibit serine palmitoyltransferase—the enzyme that catalyzes the first step in sphingolipid synthesis. In S. cerevisiae, the two Orm proteins are thought to function redundantly in suppressing sphingolipid production. Here, we

Multifunctional Nanovaccine‐Radiotherapy Synergy Drives Anti‐Tumor Immunity via Multi‐Cascade Cell Death for Pancreatic Cancer Therapy

open access: yesAdvanced Science, EarlyView.
Machine‐learning‐driven transcriptomic analysis identifies FSTL3 as a key tumor‐microenvironment regulator in desmoplastic pancreatic adenocarcinoma. A cRGD‐modified liposome co‐loading gemcitabine and siFSTL3 serves as an irradiation‐triggered in situ nanovaccine. It synergizes with radiotherapy to induce ferroptosis and immunogenic cell death through

Runx Regulation of Sphingolipid Metabolism and Survival Signaling [PDF]

open access: yesCancer Research, 2010
Abstract The Runx genes (Runx1, 2, and 3) regulate cell fate in development and can operate as either oncogenes or tumor suppressors in cancer. The oncogenic potential of ectopic Runx expression has been shown in transgenic mice that develop lymphoma in potent synergy with overexpressed Myc, and in established fibroblasts that display

SIRT5‐Mediated Desuccinylation of ACAA2 Protects Against Calcium Oxalate‐Induced Kidney Injury by Regulating Fatty Acid Oxidation to Suppress Mitochondrial Oxidative Injury and Ferroptosis

open access: yesAdvanced Science, EarlyView.
The SIRT5/ACAA2 axis maintains lipid metabolic homeostasis in RTECs by promoting ACAA2 desuccinylation and preserving its stability and enzymatic activity, thereby sustaining FAO and limiting PUFA and PUFA‐containing phospholipid accumulation. Under CaOx stress, SIRT5 downregulation impairs FAO, promotes oxidative stress and ferroptosis, and enhances ...

The GARP complex is required for cellular sphingolipid homeostasis

open access: yeseLife, 2015
Sphingolipids are abundant membrane components and important signaling molecules in eukaryotic cells. Their levels and localization are tightly regulated. However, the mechanisms underlying this regulation remain largely unknown.

The sphingolipid salvage pathway in ceramide metabolism and signaling [PDF]

open access: yesCellular Signalling, 2008
Sphingolipids are important components of eukaryotic cells, many of which function as bioactive signaling molecules. Of these, ceramide is a central metabolite and plays key roles in a variety of cellular responses, including regulation of cell growth, viability, differentiation, and senescence.

Modulation of the TGF‐β/Smad Signaling Pathway by a Bioactive Oxidized Polygonati Rhizoma Polysaccharide Crosslinked Chitosan Hydrogel as Therapeutic Carrier for Parkinson's Disease Treatment

open access: yesAdvanced Science, EarlyView.
An injectable, self‐healing COPRP hydrogel integrates structurally defined oxidized Polygonati rhizoma polysaccharide with carboxymethyl chitosan through dynamic Schiff‐base crosslinking. The bioactive matrix scavenges reactive oxygen species, suppresses neuroinflammation, protects dopaminergic neurons, and supports sustained levodopa release.

A Systems Approach for Decoding Mitochondrial Retrograde Signaling Pathways

open access: yes, 2018
Mitochondrial dysfunctions activate retrograde signaling from mitochondria to the nucleus. To identify transcription factors and their associated pathways that underlie mitochondrial retrograde signaling, we performed gene expression profiling of the ...
