Abstract

After the renal cell carcinoma related novel gene fragment GYLZ-RCC18 was cloned by using suppression subtractive hybridization (SSH), we used the SMART RACE technology to clone the full length of GYLZ-RCC18 and performed chromosome location by the FISH method. RT-PCR was used to detect the expression of the first reading frame of GYLZ-RCC18 in different stages and grades of renal cell carcinoma tissue and other tissues. Also we transfected the antisense oligonucleotide of GYLZ-RCC18 to renal cell carcinoma cell line GRC-1, and analyzed the proliferation activity, growth speed, apoptosis and mortality changes in GRC-1. The results show that the full length of GYLZ-RCC18 (GenBank accession No.: BE825133) cDNA is about 3.5 kb long which is located at No. 14 chromosome. GYLZ-RCC18 has a higher expression in higher grades and stages of renal cell carcinoma than in the lower ones. The expression of GYLZ-RCC18 in renal cell carcinoma was much higher than that in normal kidney and other tissues. After transfection of GYLZ-RCC18 antisense oligonucleotide, the mortality of GRC-1 increases evidently, the proliferation activity and growth speed were inhibited remarkably at the same time. Also the antisense oligonucleotide can induce the apoptosis of GRC-1 all through the observation time. Our results indicated that GYLZ-RCC18 is an important novel gene related to renal cell carcinoma. Its overexpression would stimulate the growth and proliferation activity and plays an antidead and antiapoptosis effect in renal cell carcinoma. Transfection of antisense oligonucleotide could inhibit the generation and development of renal cell carcinoma. The study provides a new clue for the research of renal cell carcinoma, and also provides an instruction for special genetic diagnosis and the therapy of renal cell carcinoma.
