Anti ‑inflammatory effects of gambogic acid in murine collagen‑induced arthritis through PI3K/Akt signaling pathway.

Anti‑inflammatory effects of gambogic acid in murine collagen‑induced arthritis through PI3K/Akt signaling pathway. Mol Med Rep. 2018 Jan 08;: Authors: Wang QL, Yang DZ, Lv C Abstract Garcinia angustifolia is a dry resin secreted by Garcinia cambogia, which has the functions of breaking blood, detoxifying, stopping bleeding and killing insects. It is used for the treatment of cancer and brain edema. Gambogic acid is the primary active ingredient. The present study aimed to investigate the anti‑inflammatory and antiproliferative effects of gambogic acid on arthritis and the possible mechanisms. It was demonstrated that gambogic acid decreased arthritic scores in murine collagen‑induced arthritic mice. The tumor necrosis factor (TNF)‑α, interleukin (IL)‑1β, IL‑6 and IL‑18 concentrations, and caspase‑3 and caspase‑9 were significantly inhibited by gambogic acid in arthritic mice. Gambogic acid decreased matrix metalloproteinases (MMP)‑2, MMP‑9, nuclear factor (NF)‑κB and phosphorylated‑p38 protein expression, and increased tissue inhibitors of matrix metalloproteases‑1 (TIMP‑1) protein expression in arthritic mice. Furthermore, the phosphoinositide 3‑kinase (PI3K)/AKT serine/threonine kinase (Akt) signaling pathway was induced in arthritic mice treated with gambogic acid. The results suggested that gambogic acid induced anti‑inflammatory effects in murine collagen‑induced arthritis, through the PI3K...

Platelet-dense ( δ) granules are important for platelet function. Platelets contribute to host defense and vascular integrity during pneumonia and sepsis, and δ granule products, including adenosine diphosphate (ADP), can influence inflammatory responses. We therefore aimed to study the role of platelet δ granule s in the host response during sepsis. Hermansky-Pudlak syndrome(Hps)3coa mice (with reduced δ granule content), mice treated with the platelet ADP receptor inhibitor clopidogrel, and appropriate control mice were infected with the human sepsis pathogenKlebsiella pneumoniae via the airways t...

Aspirin is best known as an over-the-counter painkiller. But acetylsalicylic acid, as it’s called chemically, has many other health benefits, as well as side effects, in the body that have only become clear in recent years. Here’s what the latest science says about the health benefits and side effects of aspirin, as well as which conditions it may treat and those it doesn’t appear to improve. (If you are taking aspirin for any reason other than for periodic pain relief, it’s best to consult with your doctor to confirm whether the benefits outweigh the risks in your particular case.) How aspirin affe...

Conclusion A growing number of today’s children suffer from vaccine damage. Most individuals do not make the connection between health problems and vaccines. When asked about the cause of autoimmune disorders, asthma, allergies, diabetes, learning disabilities, attention deficit disorder, autism, and other common childhood diseases and illness, the majority of health care providers advise patients that the causes are unknown. Doctors, including most integrative physicians, fail to make the connection to vaccines. It takes one moment to permanently damage the health of an adult or child, but t...
