Pellagra is a photosensitivity syndrome characterized by three "D's": diarrhea, dermatitis, and dementia as a result of niacin deficiency. However, the molecular mechanisms of photosensitivity dermatitis, the hallmark abnormality of this syndrome, remain unclear. We prepared niacin deficient mice in order to develop a murine model of pellagra. Niacin deficiency induced photosensitivity and seve...

Prostaglandin E2 (PGE2) has been reported to control angiogenesis and play an important role in wound healing in soft tissues, although the precise mechanism is still unknown. Since basic fibroblast growth factor (bFGF) has been reported to generate neovascularization, PGE2 and bFGF might work closely, or one might control the expression of the other. In this study, we demonstrate that PGE2 enh...

Background Acute myocardial infarction is one of the leading causes of death in the world which is caused by coronary artery thrombosis. Platelets play a central role in cardiovascular thrombosis. Platelet aggregation caused due to a ruptured artherosclerotic plaque could eventually lead to vascular occlusion. Another important component of vascular diseases is inflammation. During inflammation...

Prostaglandin E2 (PGE2) is produced in inflammatory responses and regulates a variety of immunological reactions through 4 different receptor subtypes; EP1, 2, 3 and 4. However, the precise role of each receptor in cardiovascular disease has not yet been elucidated. Enhanced expression of some EPs has been observed in clinical and experimental cardiovascular diseases. EP agonists have been deve...

Basal cell carcinoma (BCC) commonly affects the elderly and is mostly confined to the head and neck region. Only 10% of all cases occur on the trunk. We presented a case of bullous lesion on the abdomen in a young male, initially diagnosed by clinicians as a vascular nevus. Histopathological examination and immunohistochemistry (IHC) revealed it to be Nodular cystic variant of BCC. This rare va...

41 Prostaglandin E2 (PGE2) produced by the cyclooxygenase (COX) pathway regulates 42 skeletal muscle protein turnover and exercise training adaptations. The purpose of this 43 study was two-fold: 1) Define the PGE2/COX pathway enzymes and receptors in human 44 skeletal muscle, with a focus on Type I and II muscle fibers, 2) Examine the influence of 45 aging on this pathway. Muscle biopsies were...

We examined changes in electrical and morphological properties of rat osteoclasts in response to prostaglandin (PG)E(2). PGE(2) (>10 nM) stimulated an outwardly rectifying Cl(-) current in a concentration-dependent manner and caused a long-lasting depolarization of cell membrane. This PGE(2)-induced Cl(-) current was reversibly inhibited by 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid (DIDS...

Chang H, Young SH, Sinnett-Smith J, Chou CE, Moro A, Hertzer KM, Hines OJ, Rozengurt E, Eibl G. Prostaglandin E2 activates the mTORC1 pathway through an EP4/cAMP/PKAand EP1/Ca -mediated mechanism in the human pancreatic carcinoma cell line PANC-1. Am J Physiol Cell Physiol 309: C639–C649, 2015.
