Nevertheless, Smoking could interact with wild type of NAT2 and increase the relative risk of rectal adenoma recurrence significantly. It is suggested that NAT2 might involve the metabolism of pre-carcinogen generating from tobacco and alter the susceptibility of cancer. Meanwhile, the NAT2〓4 alleles encode rapid acetylator of NAT2 would increase the risk of adenoma recurrence among those high-risk people with habit of fried fish intake.

吃红烧鱼因素在NAT2的快速酶中，特别是在野生纯合型中直肠腺瘤复发的相对危险度有增高趋势，提示了NAT2〓4等位基因编码快酶型NAT，可能在红烧鱼产生的杂环胺类化合物中代谢中加速其N-乙酰基化代谢过程，从而加速其代谢为终致癌物而与肠粘膜上皮细胞的DNA产生加成物，损伤其遗传物质。

This result indicates that WT1 gene plays an important role in differentiation and development of fetal kidney and may be the factor that promotes metanephric blastemal cell to differentiate into epithelial cell.

结果显示小胎龄肾组织中WT1蛋白在胚基细胞和幼稚肾小球细胞核表达而大胎龄组肾组织中WT1在肾小管细胞胞浆表达，阳性率分别为57.1％(8/14)和46.2%(6/13)，提示WT1基因在胚胎肾分化发育的过程中起着重要作用，WT1蛋白可能是促进后肾胚基细胞向上皮细胞分化的调控因子，其表达在时间上和空间上都受到严格的调控，WT1的表达异常可能导致胚基细胞分化停滞。17例肾母细胞瘤WT1蛋白表达阳性率为41.2%(7/17)，阳性部位在胚基型和上皮型肿瘤细胞核，表达部位和阳性率与早期胚胎肾相似，其中间质型肾母细胞瘤均为阴性，胚基型和上皮型肾母细胞瘤阳性率70%(7/10)，两组间阳性率有显著差异。

Angiomyolipoma of the kidney is a clonal neoplasm, apparently part of a family of neoplasms derived from perivascular epithelial cells.

肾脏平滑肌脂肪瘤是无性系肿瘤，部分有家族史，肿瘤来自血管上皮细胞。

Long believed to be a benign hamartoma, angiomyolipoma is now considered a neoplasm that arises from perivascular epithelioid cell.

长期以来被认为是一种良性的过误瘤，但最近几年来研究认为，这是一种起源自血管旁类上皮细胞的新生性肿瘤。

The VX2 is a squamouscell carcinoma resulting from malignant change in a papilloma induced with the Shope virus in rabbits.
