Expression of CCRK in small cell lung cancer and its clinical significance / 中国医师杂志

ABSTRACT

Objective To investigate the pathogenesis of small cell lung cancer ( SCLC) and to ex-plore the expression of cell cycle related kinase ( CCRK) in SCLC and its clinical significance.Methods Reverse transcription polymerase chain reaction ( RT-PCR) and Western blot were performed to examine ex-pression of CCRK in SCLC and normal tissues.Results The expressions of gene [(0.51 ±0.11)IU/L] and protein [(0.61 ±0.13)IU/L] of CCRK in SCLC tissues were significantly higher than normal tissues [(0.30 ±0.08)IU/L, (0.34 ±0.09)IU/L] ( P 0.05 ) .Conclusions The expressions of gene and protein of CCRK in SCLC tissues were significantly higher than normal tissues. CCRK promoted the occurrence and progress of SCLC.Chem can restrain effectually the excessive expres-sion of CCRK.The expressions of gene and protein of CCRK in the different clinical curative effect group had significant difference.
