To investigate the changes of sugar chain structures of alkaline phosphatase (ALP) in hepatoma tissue and its relation to the invasiveness of hepatocellular carcinoma (HCC).
The binding ratios of ALP from 9 normal liver tissues, 16 hepatoma tissues and 16 noncancerous tissues surrounding hepatoma were analysed by affinity chromatography on various lectin columns including leukoagglutinating phytohemagglutinin (L-PHA), lentil lectin (LCA), Datura stramonium agglutinin (DSA), erythroagglutinating phytohemagglutinin (E-PHA) and Sambucus nigra bark agglutinin (SNA).
The binding ratios of ALP on L-PHA (22.94%+/-5.30%), DSA (55.97%+/-13.72%), LCA (38.16%+/-8.87%), E-PHA (11.56%+/-4.81%) and SNA (69.80%+/-13.71%) in HCC tissues were significantly increased (P<0.01) compared with that in normal liver tissues (L-PHA 5.89%+/-2.75%, DSA 36.20%+/-11.58%, LCA 17.90%+/-6.71%, E-PHA 5.38%+/-2.20%, SNA 57.32%+/-11.27%), respectively. t values between the two groups were 8.94, 3.64, 5.94, 3.62 and 2.32, respectively. L-PHA-binding ratio (25.84%+/-4.67%) of ALP in HCC with invasiveness was significantly higher than that (18.10%+/-3.64%) without invasiveness (t=3.71, P<0.01).
The changes of ALP sugar chain structures occur in HCC tissue. b1-6 branching sugar chain structure of ALP is related to the invasiveness of HCC.
研究肝癌组织中碱性磷酸酶(ALP)糖链结构的变化及其与肝细胞癌(HCC)侵袭性的关系。
采用包括白细胞凝集素(L-PHA)、扁豆凝集素(LCA)、曼陀罗凝集素(DSA)、红细胞凝集素(E-PHA)和接骨木树皮凝集素(SNA)等多种凝集素柱亲和层析法,分析9例正常肝组织、16例肝癌组织及16例肝癌旁非癌组织中ALP的结合率。
与正常肝组织(L-PHA 5.89%±2.75%,DSA 36.20%±11.58%,LCA 17.90%±6.71%,E-PHA 5.38%±2.20%,SNA 57.32%±11.27%)相比,肝癌组织中ALP在L-PHA(22.94%±5.30%)、DSA(55.97%±13.72%)、LCA(38.16%±8.87%)、E-PHA(11.56%±4.81%)和SNA(69.80%±13.71%)上的结合率均显著升高(P<0.01)。两组间的t值分别为8.94、3.64、5.94、3.62和2.32。有侵袭性的肝癌组织中ALP的L-PHA结合率(25.84%±4.67%)显著高于无侵袭性的肝癌组织(18.10%±3.64%)(t=3.71,P<0.01)。
肝癌组织中存在ALP糖链结构的变化。ALP的β1-6分支糖链结构与HCC的侵袭性有关。
