Abstract
Background: The health benefits of coixol, an active compound of adlay seed, have attracted certain attention. Adlay seed is often adopted in traditional Chinese medicine for the treatment of various inflammatory disorders. Thus, it is hypothesized that coixol could protect neuronal cells.
Objectives: The preventive effects of coixol against Abeta25-35-induced damage in nerve growth factor-differentiated PC12 cells were explored.
Methods: Differentiated PC12 cells were treated with coixol at 0.125 μM, 0.25 μM, 0.5 μM, 1 μM, and 2 μM for 48 h. Then, cells were further exposed to Abeta25-35 at 20 μM for 24 h.
Results: Coixol treatments at 0.25-2 μM exhibited antiapoptotic effect via increasing Bcl-2 mRNA expression, mitochondrial membrane potential, and Na+-K+ ATPase activity as well as decreasing Bax mRNA expression, caspase-3 activity, and intracellular Ca2+ release. In addition, coixol treatments at 0.25-2 μM alleviated oxidative and inflammatory responses via lowering reactive oxygen species level, increasing glutathione content, promoting the activity of glutathione peroxidase, glutathione reductase, and catalase, decreasing the generation of tumor necrosis factor-α, interleukin (IL)-1β, IL-6, and prostaglandin E2. Furthermore, coixol treatments at 0.25-2 μM diminished intracellular Ca2+ release, and restricted nuclear factor kappa B-binding activity and phosphorylation of p65 and p38. Coixol treatments at 0.5-2 μM increased protein generation of nuclear factor E2-related factor 2, and limited protein production of inducible nitric oxide synthase and receptor of advanced glycation end product.
Conclusion: Our novel findings suggested that coixol was a compelling agent against beta-amyloid peptide-induced neurotoxicity.
期刊介绍:
Asian Biomedicine: Research, Reviews and News (ISSN 1905-7415 print; 1875-855X online) is published in one volume (of 6 bimonthly issues) a year since 2007. [...]Asian Biomedicine is an international, general medical and biomedical journal that aims to publish original peer-reviewed contributions dealing with various topics in the biomedical and health sciences from basic experimental to clinical aspects. The work and authorship must be strongly affiliated with a country in Asia, or with specific importance and relevance to the Asian region. The Journal will publish reviews, original experimental studies, observational studies, technical and clinical (case) reports, practice guidelines, historical perspectives of Asian biomedicine, clinicopathological conferences, and commentaries
Asian biomedicine is intended for a broad and international audience, primarily those in the health professions including researchers, physician practitioners, basic medical scientists, dentists, educators, administrators, those in the assistive professions, such as nurses, and the many types of allied health professionals in research and health care delivery systems including those in training.
