Transcribed ultra-conserved region (T-UCR) transcripts are a novel class of long non-coding RNAs (lncRNAs) transcribed from ultra-conserved region which is highly conserved in human, rat, and mouse genome. LncRNA UC.173 has been found significantly down-regulated in lead-exposed population and lead-exposed animal mode, and had an inhibitory effect on lead-induced nerve cell apoptosis. We supposed that lncRNA UC.173 had an inhibitory effect on lead-induced renal tubular epithelial cell apoptosis. Thus, the aim of our study was to explore the function of lncRNA UC.173 in lead-exposed renal tubular epithelial cells. In our results, lead exposure inhibited renal tubular epithelial cells viability and promoted cell apoptosis and apoptosis-associated genes expression, but no effect on cell-cycle distribution. Lead exposure inhibited the expression of lncRNA UC.173 in renal tubular epithelial cells, and the inhibition effect was time-dependent and concentration-dependent. Upregulation of lncRNA UC.173 had no effect on renal tubular epithelial cell viability, cell cycle and apoptosis, but significantly rescued lead-induced inhibition of renal tubular epithelial cell viability and suppressed lead-induced cell apoptosis. In summary, our experiments suggest that lncRNA UC.173 is certainly involved in the regulation of lead-induced renal tubular epithelial cell apoptosis, which may supply a new strategy to minimize lead-induced nephrotoxicity.
