摘要
为探讨人结直肠癌组织中MTS1/ p16基因的缺失情况 ,利用逆转录聚合酶链反应来检测取自结直肠癌患者的 6 0例手术切除组织标本中MTS1/ p16基因的等位缺失情况 ,其中结直肠癌组织 35例 ,癌旁组织 15例及结直肠正常粘膜组织 10例。结果显示 ,17 14 % ( 6 / 35 )的结直肠癌组织标本出现MTS1/p16基因的等位缺失 ,而癌旁组织及结直肠正常粘膜均未出现MTS1/ p16基因的缺失。提示MTS1/ p16基因的缺失在结直肠癌进展过程中可能起着一定的促进作用。
To investigate the deletion of MTS1/p16 gene in human colorectal carcinoma,the homozygous deletion of MTS1/p16 gene was checked by reverse transcriptase polymerase chain reaction from 60 patients with colorectal carcinoma.The specimens consisted of 35 colorectal carcinoma,15 tumor-adjacent tissues and 10 normal colorectal mucosa. It was found that 17 14% (6/35) colorectal carcinoma specimens showed homozygous deletion of MTS1/p16 gene.No deletion was detected in tumor-adjacent tissue and normal colorectal mucosa.Deletion of MTS/p16 gene may play a role in the progression of colorectal carcinoma.
