Results In pancreatic cancer patients the positive rate of plasma K - ms gene mutation was 73 %, without false positivity, and higher than that in the pancreatic juice and duodenal juice, but lower than that in the fine - needle aspirates. Plasma K - ras gene mutation was not found in patients with benign pancreatic disease and healthy subjects.

结果 胰腺癌患者血浆K-Fas基因的突变阳性率为73％，无假阳性率，高于胰液、十二指肠液的检测率，低于细针穿刺的检测率；胰腺良性病变患者及健康对照者血浆中未检测到K-ras基因的突变；胰腺癌组K-ras基因突变与非胰腺癌组及健康对照组相比具有显著性差别。

The RhoA oncogene , have been revealed in recent years, are closely related to various malignant tumours. RhoA, belonging to Rho family, is one member of the ras superfamily, whose encoding production, namely RhoA protein, pertaining to micromolecular mass GTP conjugated protein family, in GTP conjunctive active form and GDP conjunctive unreactive form. It exist in the latter form in normal cells and the switch of the two forms enables them to educe functions, paralleling"molecular switch", the diminutive G protein in activated state being able to activate the wink dromo-iter to work functions, which is in the resemblance of process during which the Ras genic mutation induces its continous activations.

RhoA是近年来新发现的与多种恶性肿瘤密切相关的癌基因，RhoA属于Rho亚家族，是ras基因超家族的一员，其编码产物RhoA蛋白属于小分子量GTP结合蛋白族，分为GTP结合的活性型和GDP结合的非活性型两类，在正常细胞内以GDP结合的非活性型存在，两种活性形式之间的转换使他们能够发挥一种类似&分子开关&的作用，活性态的小G蛋白能激活下游的信号传导通路，行使其功能。
