Abstract

Using suppression subtractive hybridization, a renal cell carcinoma (RCC) cDNA subtractive library which only contains differently expressed cDNAs between human RCC and normal kidney has been constructed. 200 clones were picked out randomly to perform enzyme digest analysis, a part of them underwent sequence analysis and Northern blot to identify RCC specially expressed genes. Results showed that 190 clones contain 50 - 400 bp inserts respectively. Sequence analysis was performed in 10 clones. All the 10 sequences were unknown before and derived from 6 unique novel genes among which the cDNA insert RCC18 has five copies. Northern blot analysis showed that RCC18 cDNA expressed highly in RCC, but there was no signal detected in normal kidney, and the full length of RCC18 was about 2.5 kb. The constructed cDNA subtractive library of human RCC is a highly efficient one and lays the solid foundation for large-scale screening and cloning new and specific oncogenes or tumor suppressor genes of RCC. The novel specially expressed genes provided an important clue for researching the mechanism of the occurrence and development of RCC.
