Capped RLM-RACE of stomach tissue and uncapped inverse PCR of the PC3 prostate cancer cell line (Fig. 1) indicated that a GHRLOS promoter (exon I) was present at the very end of the 2 kb 3' untranslated exon 8 of TATDN2. Moreover, we discovered that multiple Cap Analysis of Gene Expression (CAGE) tags are clustered approximately 1.5 kb upstream of the GHRLOS transcription start sites found via 5' RLM-RACE. This evidence concerns the gene TATDN2 and prostate cancer.
