The results indicated that the damage effect of NO on nuclear DNA in esophageal carcinoma cells might depend on its concentration and its exposing time.
以硝普钠 ( Sodium Nitroprusside,SNP)作为 NO( Nitric oxide)的体外供体 ,以食管癌细胞系 EC1 0 9作为细胞模型 ,采用单细胞凝胶电泳法检测不同浓度的 NO作用不同时间后 ,食管癌细胞核 DNA被损伤的情况 。
2.
Purpose: To study the effect of nitric oxide (NO) in various concentrations on the nuclear DNA damage in esophageal carcinoma cells.

Since 2000, our group found that NGAL overexpression played an important role in the process of malignant transformation of human immortalized esophageal epithelial cells and was involved in the invasion of esophageal carcinoma cells via protecting the activity of MMP-9 from degradation.
2000年以来,我们课题组相继研究发现, NGAL在人食管上皮细胞癌变中异常过表达; NGAL异常过表达可促进食管癌细胞的侵袭移动; NGAL促进食管癌细胞侵袭移动主要由MMP-9等介导;下调NGAL表达可使食管癌细胞的微丝骨架和形态结构发生显著改变,促进癌细胞分化,与癌细胞的前体细胞/永生化食管上皮细胞的形态特征趋于一致。
补充资料：未分化癌
未分化癌
undifferentiated carcinoma
来源于上皮细胞的恶性肿瘤，但分化差，不能分清起源上皮细胞的特征。起源于腺体及导管的癌无腺腔和腺管分化，起源于鳞状上皮细胞的癌无角化现象。硬癌、髓样癌多属未分化腺癌或低分化癌。由于起源于上皮细胞的肿瘤失去上皮细胞特点，所以与肉瘤鉴别困难。应用免疫组织化学，若角蛋白阳性，一般可排除肉瘤。
