“…Tumor specific changes in expression of miR-224 negatively correlated with changes in DIO1 expression and intracellular T3 concentration. Transfection of HeLa cell line with miR-224 and miR-383 suppressed the activity of a luciferase reporter containing the 3′UTR of DIO1. …”

“…To address this issue, we have studied NER in human HeLa cell extracts of two topologically distinct lesions, one derived from benzo[a]pyrene (10R-(+)-cis-anti-B[a]P-N(2)-dG), and one from the food mutagen 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (C8-dG-PhIP), embedded in either full or ‘deletion’ duplexes (the partner nucleotide opposite the lesion is missing). …”

“…The demonstration of a protective role of REHbβP in epididymal epithelial cells (EPEC's) led us to investigate: (1) the identification of LPS interactive domain in REHbβP, and (2) whether the REHbβP of rabbit origin mediates vaginal cellular immune responses of another species (human). HeLa-S3, human vaginal epithelial cells (hVECs) were exposed to LPS or the LPS-stimulated cells treated with REHbβP or neutral peptide, nREHbβP. …”

“…Using information from ion intensities we have estimated protein abundance levels and using rates of change in stable isotope labeling with amino acids in cell culture isotope ratios we measured turnover rates and subcellular distribution for the HeLa cell proteome. Protein isoforms were detected using three data analysis strategies that evaluate differences between stable isotope labeling with amino acids in cell culture isotope ratios for specific groups of peptides within the total set of peptides assigned to a protein. …”
