Abstract Background Antisense transcription yielding both coding and non-coding RNA is a widespread phenomenon in mammals. The mechanism by which natural antisense transcripts NAT may regulate gene expression are largely unknown. The aim of the present study was to explore the mechanism of reciprocal sense-antisense S-AS regulation by studying the effects of a coding and non-coding NAT on corresponding gene expression and to investigate the possible involvement of endogenous RNA interference RNAi in S-AS interactions. Results We have examined the mechanism of S-AS RNA base pairing using thymidylate synthase and hypoxia inducible factor-1a as primary examples of endogenous genes with coding and noncoding NAT partners respectively. Here we provide direct evidence against S-AS RNA duplex formation in the cytoplasm of human cells and subsequent activation of RNAi. Conclusion Collectively our data demonstrate that NAT regulation of gene expression occurs .
