Expreesion of c-mys gene in gastrocarcinoma[J]. Nuclear techniques, 1994, (5).
以32P-c-myc-cDNA和32P-c-myc-DNA为探针,采用核酸杂交方法研究24例胃癌、6例胃溃疡正常胃组织c—myc的表达。RNA—DNAdot证实,7例胃髓样癌、3例粘液癌和14例腺癌分别有3、1和1例c-myc高表达。Northernblot表明.胃癌组织c-mycmRNA分子量同对照组无差异;Southernblot未发现c—myc扩增与重排。指明胃癌组织c-myc高表达与c-myc结构改变无关。
he expression of c-myc gene on 24 cases of gastrocarcinoma and 6 cases of gastric ulcer was studied by nucleic acid hybridization with 32P c-myc-cDNA and abp c-myc-DNA as probes. RNA-DNA dot showed high expression in 3/7 medullary gastrocarcinoma
1/3 mucoid agstrocarcinoma and 1/14 gastric adenocarcinoma.Molecular weight of c-myc mRNA in tumor tissue had no significant change compared with control.No multiplication and rearrangement were discovered by southern blot.
