Reduced expression of nm23 RNAs/proteins has been associated previously with high tumor metastatic potential. In contrast, we report that regional (state III) and metastatic (stage IV) childhood neuroblastomas exhibit elevated nm23 RNA levels as compared with localized tumors. Elevated neuroblastoma nm23 RNA levels were associated with significant(More)
The aim of the study was to detect the regulated in development and DNA responses (REDD1) in human placentas throughout different gestational ages (GAs) and to correlate REDD1 with preeclampsia (PE). In experiments, REDD1 messenger RNA and protein expression levels throughout the gestation were determined using immunohistochemistry, quantitative reverse(More)
The extracellular matrix (ECM) of developing mammalian enamel comprises a complex of unusual epithelial-derived proteins, which appear to function in concert to initiate and propagate tissue-specific biomineralization. Following enamel protein synthesis by ameloblast cells within the enamel organ, the subsequent steps of posttranslational modification,(More)
