To elucidate the role of fusions between ALK and other genes in pulmonary carcinogenesis, we examined 77 non-small cell lung carcinomas (NSCLCs) for EML4-, NPM-, TPM3-, CLTC-, ATIC-, and TFG-ALK fusion transcripts by RT-PCR and subsequent sequencing analysis.     ///    "Although no expression of NPM-, TPM3-, CLTC-, ATIC-, or TFG-ALK fusion transcripts were detected in any of the cases, expression of EML4-ALK fusion transcripts was detected in two (2.6%) of the 77 NSCLCs. "    ///    "EML4-ALK fusion transcripts, but no NPM-, TPM3-, CLTC-, ATIC-, or TFG-ALK fusion transcripts, in non-small cell lung carcinomas.. "
