Effects of Resveratrol on Benign Prostatic Hyperplasia by the Regulation of Inflammatory and Apoptotic Proteins

25.02.2015 | Kyung-Sook Chung; Se-Yun Cheon; Hyo-Jin An, Journal of Natural Products, 2015

Resveratrol (1) is a natural polyphenolic compound that has cardioprotective, anticancer, and anti-inflammatory properties. Although diverse biological studies of compound 1 have been conducted, no antiproliferative effects of 1 have been reported in benign prostatic hyperplasia (BPH). BPH is a ...

The reverse transcriptase–RNase H: from viruses to antiviral defense

19.02.2015 | Karin Moelling, Felix Broecker, Annals of the New York Academy of Sciences, 2015

Ubiquitous, reverse transcriptase may have contributed to the transition from the RNA to the DNA world, a transition that also involved RNase H–like activities. Both enzymes shaped various genomes and antiviral defense systems as endogenous retroviruses (ERVs) and transposable elements (TEs). A ...

Necrotic cell death caused by exposure to graphitic carbon‐coated magnetic nanoparticles

17.02.2015 | Jung‐Hee Kim, Jakkid Sanetuntikul, Sangaraju Shanmugam, Eunjoo Kim, Journal of Biomedical Materials Research Part A, 2015

Abstract We synthesized graphitic carbon‐coated magnetic nanoparticles (Fe@C NPs) and evaluated their physicochemical properties and mechanism of cytotoxicity in vitro. The structure of these nanocomposites consisted of an iron core encapsulated by a graphitic‐carbon shell. The diameter of ...

Influence of Intracellular Zinc on Cultures of Rat Cardiac Neural Crest Cells

16.02.2015 | Hsunhui Yang, Carl L. Keen, Louise Lanoue, Birth Defects Research Part B: Developmental and Reproductive Toxicology, 2015

BACKGROUND Developmental zinc (Zn) deficiency increases the incidence of heart anomalies in rat fetuses, in regions and structures derived from the outflow tract. Given that the development of the outflow tract requires the presence of cardiac neural crest cells (cNCC), we speculated that Zn ...

Cyclooxygenase-1 Serves a Vital Hepato-Protective Function in Chemically Induced Acute Liver Injury

01.02.2015 | Jia Xiao; Emily C. Liong; Hai Huang; Wing On Tse; Kam Shing Lau; Jingfei Pan; Amin A. Nanji; Man Lung Fung; Feiyue X ..., Toxicological Sciences, 2015

Cyclooxygenase-1 (COX-1) is the constitutive form of the COX enzyme family, which produces bioactive lipids called prostanoids. Although the role of COX-2 in liver diseases has been studied, little is known about the function of COX-1 in liver injury. We aimed to investigate the role and ...
