Inhibition of mPGES-1 or COX-2 Results in Different Proteomic and Lipidomic Profiles in A549 Lung Cancer Cells.

Pharmacological inhibition of microsomal prostaglandin E synthase (mPGES)-1 for selective reduction in prostaglandin E (PGE) biosynthesis is protective in experimental models of cancer and inflammation. Targeting mPGES-1 is envisioned as a safer alternative to traditional non-steroidal anti-inflammatory drugs (NSAIDs). Herein, we compared the effects of mPGES-1 inhibitor Compound III (CIII) with the cyclooxygenase (COX)-2 inhibitor NS-398 on protein and lipid profiles in interleukin (IL)-1β-induced A549 lung cancer cells using mass spectrometry.

Targeted lipidomics analysis identified altered serum lipid profiles in patients with polymyositis and dermatomyositis.

Background: Polymyositis (PM) and dermatomyositis (DM) are severe chronic autoimmune diseases, characterized by muscle fatigue and low muscle endurance. Conventional treatment includes high doses of glucocorticoids and immunosuppressive drugs; however, few patients recover full muscle function. One explanation of the persistent muscle weakness could be altered lipid metabolism in PM/DM muscle tissue as we previously reported.

Paediatric ventilation treatment of acute lung injury in Nordic intensive care units.

Background: Treatment of acute respiratory distress syndrome (ARDS) in children is largely based on extrapolated knowledge obtained from adults and which varies between different hospitals. This study explores ventilation treatment strategies for children with ARDS in the Nordic countries, and compares these with international practice.

Methods: In October 2012, a questionnaire covering ventilation treatment strategies for children aged 1 month to 6 years of age with ARDS was sent to 21 large Nordic intensive care units that treat children with ARDS.

A passion for parasites.

I knew nothing and had thought nothing about parasites until 1971. In fact, if you had asked me before then, I might have commented that parasites were rather disgusting. I had been at the Johns Hopkins School of Medicine for three years, and I was on the lookout for a new project.

TbKAP6, a mitochondrial HMG box-containing protein in Trypanosoma brucei, is the first trypanosomatid kinetoplast-associated protein essential for kinetoplast DNA replication and maintenance.

Kinetoplast DNA (kDNA), the mitochondrial genome of trypanosomatids, is a giant planar network of catenated minicircles and maxicircles. In vivo kDNA is organized as a highly condensed nucleoprotein disk. So far, in Trypanosoma brucei, proteins involved in the maintenance of the kDNA condensed structure remain poorly characterized.
