[Abstract] Objective To investigate the mRNA expression of syndecan-1 and heparanase 1 in colorectal cancer,and their relationship between the progression and prognosis of the diseases. Methods In situ hybridization was used to examine mRNA expression of syndecan-l and HPA1 in 177 specimens of colorectal cancer.The relationship between mRNA expression and pathology indicators as well as prognosis of disease was observed. Results The positive numbers of syndecan-1 mRNA and HPA1 mRNA were 75 cases and 99 cases.The expression of syndecan-1 mRNA and HPA1 mRNA were related to tumor invasion depth,lymph node metastasis,TNM,distant metastasis and vessel invasion (P<0.01).There was a negative relationship between Syndecan-1 mRNA and HPA1 mRNA expression (P<0.01).The mean survival time of cases with low expression of syndecan-1 mRNA was significantly shorter than that of cases with high expression.The mean survival time of heparanase mRNA positive cases was significantly shorter than that of cases with negative expression. Conclusion The low expression of syndecan-1 and positive expression of HPA1 can predict the invasion and metastasis of colorectal cancer.They can be used as markers of progression and prognosis of colorectal cancer.

近三十年来,跟着环境和生活方式等要素的改动,我国结直肠癌的发病率敏捷添加,已成为增加最快的肿瘤之一[1-2]。Syndecan-1作为一种跨膜硫酸乙酰肝素蛋白多糖(HSPGs),是胞外基质的重要组成成分。新近研讨发现,Syndecan-1与整合素、钙黏素等一起构成细胞间黏附分子复合体,参加胞间和胞外基质之间的黏附,具有促进细胞增殖,按捺肿瘤成长、搬运,保持细胞分解等效果[3]。而乙酰肝素酶1(heparanase 1,HPA1)能够降解HSPGs的糖类侧链,促进肿瘤细胞滋润和搬运[4]。现在关于两者对结直肠癌的转归状况报导较少,为此本研讨检测了Syndecan-1和HPA1在结直肠癌安排中的表达水平,评论它们对结直肠癌搬运和预后的影响。

1 材料与办法

1.1 一般材料

搜集2002年6月~2007年12月在本院消化内科和胃肠外科手术切除的原发性结直肠癌标本177例,一切患者术前均未承受放化疗,其中男129例,女48例;年纪39~76岁,均匀54.8岁。除随访中逝世的病例,其他病例均随访5年以上,随访截止日期为2013年12月。生计期为从手术日期至随访截止日期或逝世日期。一切患者均签属知情同意书,本研讨通过医院道德委员会同意。

1.2 试验办法

标本惯例固定、脱水,白腊包埋,切片后走Syndecan-1和HPA1 mRNA原位杂交检测。Syndecan-1和乙酰肝素酶寡核苷酸探针以及原位杂交试剂盒均购自武汉博士德公司,操作程序严厉依照阐明书进行。选用Masola等[5]引荐的办法,由2位病理医生选用双盲法作出判别,细胞质染成棕黄色颗粒为Syndecan-1和HPA1 mRNA阳性体现。依据阳性细胞占悉数肿瘤细胞的百分比进行分级:<10%为(-);10%~50%为(+);51%~75%为(++);>75%为(+++)。Syndecan-1表达(-)~(+)为低表达组,(++)~(+++)为高表达组。将HPA1 mRNA(-)者归为阴性表达组,(+)~(+++)者为阳性表达组。

1.3 统计学处理

所得数据选用SPSS 13.0软件进行统计学剖析,选用χ2查验剖析Syndecan-1、HPA1 mRNA表达与各项病理目标的联系,选用秩和查验进行Syndecan-1和乙酰肝素酶相关性剖析,生计剖析运用Kaplan-Meier法,用寿数表法核算生计率,用Log-rank查验进行比较,以P<0.05为差异有统计学含义。

2 成果

2.1 Syndecan-1 mRNA、HPA1 mRNA的表达与结直肠癌病理目标的联系

在结直肠癌177例标本中,Syndecan-1 mRNA高表达者为75例(42.4%),低表达者102例(57.6%);HPA1 mRNA阴性表达78例(44.1%),阳性表达99例(55.9%)。在结直肠癌标本中,Syndecan-1 mRNA和HPA1 mRNA阳性颗粒在细胞质上色(图1、图2)。Syndecan-1 mRNA和HPA1 mRNA的表达在肿瘤滋润深度、TNM分期、淋巴结搬运、远处搬运和脉管癌栓中差异有统计学含义(P<0.01)(表1)。Syndecan-1 mRNA与HPA1 mRNA的表达呈显着负相关(r=-0.832,P<0.01)。

2.2 Syndecan-1 mRNA、HPA1 mRNA表达与结直肠癌预后的联系

Syndecan-1 mRNA高表达患者的均匀生计时刻为65.2个月,是低表达组的2.1倍(31.3个月),5年生计率(51.6%)显着高于低表达组(26.4%)(χ2=25.97,P<0.05)(图3)。HPA1 mRNA阴性表达患者的均匀生计时刻为67.6个月,是阳性表达组的2.2倍(30.7个月),5年生计率(53.2%)显着高于阳性组(24.6%)(χ2=23.19,P<0.05)(图4)。

3 评论

Syndecan-1是Syndecan宗族的一种表达于老练上皮细胞、浆细胞、前B细胞外表的跨膜蛋白聚糖,其硫酸乙酰肝素侧链上可特异性地结合多种生物活性分子,与脂蛋白、病原体等胞吞吐效果有关[6-7]。有研讨发现,Syndecan-1在细胞膜上的表达对保持正常肠道黏膜细胞的形状至关重要;其在大肠腺瘤向大肠癌的转化中表达缺失[8]。本研讨成果显现,结直肠癌安排Syndecan-1表达下降与滋润深度、脉管侵略、淋巴结搬运、远处搬运,TNM分期密切相关,阐明Syndecan-1参加了断直肠癌侵袭搬运的进程。现在研讨发现,在机体许多恶性肿瘤构成、搬运进程中,肿瘤细胞外表的Syndecan-1蛋白表达显着削减,导致细胞损失成长按捺功用[9],使肿瘤细胞能很多增殖,并具有极强的侵袭活性[10],这与本研讨定论根本契合。Syndecan-1表达下降的患者,5年生计率显着低于高表达者,提示该基因表达程度或许成为评价结直肠癌预后的目标。

HPA1多在免疫器官、滑润肌细胞等处表达,其机制包含促进肿瘤血管生成[11]、免疫监视逃逸,改动细胞间、细胞与基质间的黏附等[12]。许多研讨发现,HPA1在实体肿瘤安排中的表达与临床病理材料有显着相关性,提醒了HPA1与肿瘤开展的相互联系[13-14]。本研讨成果显现,HPA1的表达与结直肠癌滋润深度、淋巴结搬运、脉管侵略及远处搬运等均呈正相关,且阴性表达组5年生计率显着高于阳性组。这进一步证明了HPA1与结直肠癌的侵袭和预后显着相关,与相关文献相似[15]。

亚洲人(特别是东亚人)结直肠癌的发作敏捷,往往没有腺瘤这一阶段,这使得结直肠癌前期发现难度较大[16]。Syndecan-1和HPA1是很有远景的切入点,能够对结直肠癌成长全程监控,并为评价病况和预后供给有力的参阅。

综上所述,Syndecan-1和HPA1对肿瘤的成长、侵袭和搬运具有协同效果;联合检测Syndecan-1和HPA1有助于结直肠癌患者术后评价效果和判别预后。
