Abstract:

目的 研究磷脂酰肌醇3-激酶(PI3K)和磷酸化蛋白激酶B(p-Akt)在人膀胱尿路上皮癌组织中的表达特征及临床意义。方法 2005年6月-2010年7月,采用免疫组织化学法检测40例膀胱尿路上皮癌组织及10例正常膀胱组织PI3K与p-Akt的表达,并对结果进行统计学分析。结果 PI3K和p-Akt在正常膀胱黏膜组织阳性表达率均低于膀胱尿路上皮癌组织中,差异均有统计学意义(P<0.05)。同一标本中PI3K和p-Akt的表达不具有相关性(r=0.051,P=0.747)。结论 PI3K、p-Akt在膀胱尿路上皮癌中高表达,两者在膀胱尿路上皮癌中共同促其发展,但其在膀胱尿路上皮癌的预后和进展中的作用尚不明确。
