Objective To screen the differentially expressed key molecules of HAb18G/CD147 signal transduction pathway in human hepatoma cells. Methods The total RNA was extracted from SMMC-7721 and T7721 cells, which were stably transfected and overexpressed HAb18G/CD147, and then detected by signal transduction-related microarray to identify differentially expressed key molecules. Results The microarray data indicated that there were 13 differentially expressed genes between T7721 and SMMC-7721 cells. In T7721 cell line which overexpressed HAb18G/CD147, the down-regulated genes included bone morphogenetic protein-2 (BMP-2), BMP-5, endothelin-1 (ET-1), Wnt1-induced signaling proteins-2/CCN5 (WISP-2), cysteine-rich 61/CCN1 (Cyr61), prostate stem cell antigen (PSCA), and the up-regulated genes included interleukin-10 receptor α (IL-10Rα), IL-6, IL-8, CXCL2, mitochondrial superoxide dismutase 2 (SOD2), B factor and βig-h3...

Activation of RhoA, a low molecular-weight G-protein, plays an important role in protecting the heart against ischemic stress. Studies using non-cardiac cells demonstrate that the expression and subsequent secretion of the matricellular protein CCN1 is induced by GPCR agonists that activate RhoA. In this study we determined whether and how CCN1 is induced by GPCR agonists in cardiomyocytes and examined the role of CCN1 in ischemic cardioprotection in cardiomyocytes and the isolated perfused heart. In neonatal rat ventricular myocytes (NRVMs), sphingosine 1-phosphate (S1P), lysophosphatidic acid (LPA) and endothelin-1 induced robust increases in CCN1 expression while phenylephrine, isoproterenol and carbachol had little or no effect...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
