Sodium valproate ablates ferroptosis in kainic acid-induced epileptic seizure via suppressing lysyl oxidase.

The objective of this study is to explore whether sodium valproate (VPA) alleviates epileptic seizures via suppressing lysyl oxidase (Lox)-mediated ferroptosis. Epileptic seizure mouse model was prepared via intrahippocampal injection of kainic acid (250 ng/μl). After treatment with kainic acid, VPA was injected intraperitoneally by the dose of 250 mg/kg twice daily for 4 days.

The romantic history of signaling pathway discovery in cell death: an updated review.

Cell death is a fundamental physiological process in all living organisms. Processes such as embryonic development, organ formation, tissue growth, organismal immunity, and drug response are accompanied by cell death. In recent years with the development of electron microscopy as well as biological techniques, especially the discovery of novel death modes such as ferroptosis, cuprotosis, alkaliptosis, oxeiptosis, and disulfidptosis, researchers have been promoted to have a deeper understanding of cell death modes.

Characterization the prognosis role and effects of snoRNAs in melanoma patients.

Melanoma is a melanocyte-derived malignant cancer and is known for its early metastasis and high mortality rates. It is a highly cutaneous tumour disease that could be related to the abnormal immune microenvironment, and the identification of reliable diagnostic and prognostic markers is crucial for improving patient outcomes. In the search for biomarkers, various types of RNAs have been discovered and recognized as reliable prognostic markers.

Combination of omalizumab with allergen immunotherapy versus immunotherapy alone for allergic diseases: A meta-analysis of randomized controlled trials.

Background: Allergen immunotherapy (AIT)-associated adverse events (AEs) limit its usage in the management of allergic diseases. The monoclonal anti-IgE antibody (omalizumab) and AIT have complementary actions. However, no consensus has been reached on whether their combination could exert superior efficacy and safety.

Baicalein Exerts Neuroprotective Effects in FeCl-Induced Posttraumatic Epileptic Seizures Suppressing Ferroptosis.

Posttraumatic epilepsy (PTE) is a prevalent type of acquired epilepsy secondary to traumatic brain injury, and is characterized by repeated seizures. Traditional antiepileptic drugs have minimal response in preventing posttraumatic epileptic seizures. It is essential for the development of new therapeutic strategy.

Targeting gap junction in epilepsy: Perspectives and challenges.

Gap junctions (GJs) are multiple cellular intercellular connections that allow ions to pass directly into the cytoplasm of neighboring cells. Electrical coupling mediated by GJs plays a role in the generation of highly synchronous electrical activity. Accumulative investigations show that GJs in the brain are involved in the generation, synchronization and maintenance of seizure events.

Sodium Valproate Ameliorates Neuronal Apoptosis in a Kainic Acid Model of Epilepsy via Enhancing PKC-Dependent GABAR γ2 Serine 327 Phosphorylation.

GABA is a dominant inhibitory neurotransmitter in the brain and A type GABA receptor (GABAR) phosphorylation is critical for GABA-mediated inhibitory effect. However, its role in the neuroprotective effect of sodium valproate (VPA), a prevalent drug for treating patients with epilepsy, remains elusive. The present study was conducted to explore the role of GABAR phosphorylation in the neuroprotection of VPA against a kainic acid-induced epileptic rat model and the potential molecular mechanisms.

12/15 lipoxygenase: A crucial enzyme in diverse types of cell death.

The 12/15-lipoxygenase (12/15-LOX) enzymes react with polyunsaturated fatty acids producing active lipid metabolites that are involved in plethora of human diseases including neurological disorders. A great many of elegant studies over the last decades have contributed to unraveling the mechanism how 12/15-lipoxygenase play a role in these diseases. And the way it works is mainly through apoptosis.

Gap junction as an intercellular glue: Emerging roles in cancer EMT and metastasis.

Metastasis is a common phenomenon in the progression and dissemination of cancer. It is estimated that metastasis accounts for 90% cancer-related mortality. Although the formation of tumor metastasis is relatively well understood, the underlying molecular mechanisms responsible for the emergence of aggressive cancer phenotype are still elusive.

XsFAD2 gene encodes the enzyme responsible for the high linoleic acid content in oil accumulated in Xanthoceras sorbifolia seeds.

Background: Xanthoceras sorbifolia Bunge is a valuable oilseed tree that has linoleic acid-rich seed oil. Microsomal oleate desaturase (FAD2; EC 1.3.

Two novel diacylglycerol acyltransferase genes from Xanthoceras sorbifolia are responsible for its seed oil content.

Xanthoceras sorbifolia is an excellent model system for studying triacylglycerol (TAG) biosynthesis in woody oilseed plants due to the high amount of seed oil, which is important for food and industrial uses. TAG is the major form of stored lipids in seeds and diacylglycerol acyltransferase (DGAT; EC 2. 3.
