Calcium Ions Stimulate the Hyperphosphorylation of Tau by Activating Microsomal Prostaglandin E Synthase 1

Frontiers in Aging Neuroscience, 2019
Alzheimer’s disease (AD) is reportedly associated with the accumulation of calcium ions (Ca2+), and this accumulation is responsible for the phosphorylation of tau.

Severity of lung injury in cyclooxygenase-2-deficient mice is dependent on reduced prostaglandin E-2 production [PDF]

, 2004
Levels of prostaglandin E-2 (PGE(2)), a potent inhibitor of fibroblast function, are decreased in the lungs of patients with pulmonary fibrosis, which has been shown to be because of limited expression of cyclooxygenase-2 (COX-2).

Cyclooxygenase-2-Prostaglandin E2 pathway: A key player in tumor-associated immune cells

Frontiers in Oncology, 2023
Cyclooxygenases-2 (COX-2) and Prostaglandin E2 (PGE2), which are important in chronic inflammatory diseases, can increase tumor incidence and promote tumor growth and metastasis.

Prostaglandin E2-induced inflammation: Relevance of prostaglandin E receptors

Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2015
Prostaglandin E2 (PGE2) is one of the most typical lipid mediators produced from arachidonic acid (AA) by cyclooxygenase (COX) as the rate-limiting enzyme, and acts on four kinds of receptor subtypes (EP1-EP4) to elicit its diverse actions including pyrexia, pain sensation, and inflammation.

Role of the prostaglandin E2/E-prostanoid 2 receptor signalling pathway in TGFβ-induced mice mesangial cell damage

Bioscience Reports, 2014
The prostaglandin E2 receptor, EP2 (E-prostanoid 2), plays an important role in mice glomerular MCs (mesangial cells) damage induced by TGFβ1 (transforming growth factor-β1); however, the molecular mechanisms for this remain unknown.

Seminal plasma and prostaglandin E2 up-regulate fibroblast growth factor 2 expression in endometrial adenocarcinoma cells via E-series prostanoid-2 receptor-mediated transactivation of the epidermal growth factor receptor and extracellular signal-regulated kinase pathway [PDF]

, 2007
Prostaglandin E(2) (PGE(2)) has been shown to modulate angiogenesis and tumour progression via the E-series prostanoid-2 (EP2) receptor. Endometrial adenocarcinomas may be exposed to endogenous PGE(2) and exogenous PGE(2), present at high concentration ...

Prostaglandin E2-Induced Cell Death is Mediated by Activation of EP2 Receptors in Motor Neuron-like NSC-34 Cells

Journal of Pharmacological Sciences, 2013
.: Prostaglandin E2 (PGE2) was shown to induce neuronal death in the CNS. To characterize the neurotoxicity of PGE2 and E-prostanoid receptors (EP) in motor neurons, we investigated PGE2-induced cell death and the type(s) of EP responsible for mediating ...

Reprogramming of arachidonate metabolism confers temozolomide resistance to glioblastoma through enhancing mitochondrial activity in fatty acid oxidation

Journal of Biomedical Science, 2022
Background Sp1 is involved in the recurrence of glioblastoma (GBM) due to the acquirement of resistance to temozolomide (TMZ). Particularly, the role of Sp1 in metabolic reprogramming for drug resistance remains unknown.
