Abstract

Suppression subtractive hybridisation (SSH) was performed comparing normal bronchial epithelial cells with a lung squamous cell carcinoma (SCC) and a metastatic small-cell lung carcinoma (SCLC). The sequence analysis of four cDNA libraries revealed 869 individual sequences. Of these, 342 were tested using northern blots of lung cancer cell lines representing the three major subtypes (SCC, adenocarcinoma, SCLC) which confirmed the differential expression of 236 cDNAs. The extended analysis of 31 randomly chosen fragments confirmed the validity of the approach to identify genes associated with lung cancer development. Additionally, five novel full-length cDNA were isolated encoding the microtubule-associated proteins 1A/1B light chain 3, the epithelial V-like antigen 1 (EVA1), the GTP-binding protein SAR1, a new member of the S100-type calcium binding protein family and a new homeobox-containing gene.
