【摘要】：目的:檢測β-catenin、Wnt3a和Lgr5在不同宮頸組織中的表達情況,并分析三者之間表達相關性,探討三者與宮頸癌發(fā)生發(fā)展的關系。方法:采用免疫組織化學法(SP法)檢測不同宮頸組織標本中β-catenin、Wnt3a和Lgr5的表達,包括宮頸癌組織61例,宮頸上皮內瘤變組織30例(CINI12例,CINII-III 18例),正常宮頸組織19例.結果:1.β-catenin正常情況下為連續(xù)的包膜表達,病理狀態(tài)時,則出現(xiàn)胞膜表達的缺失,胞質/核內出現(xiàn)不同程度的異常表達。β-catenin異常表達率在正常宮頸組織組5.26%(1/19),CINI組33.33%(4/12),CINII-III組38.89%(7/18),CC組75.41%(46/61),4組比較(χ_2=32.958,P0.05),有統(tǒng)計學意義;在CC組G1、G2、G3各級的異常表達率分別為41.67%(5/12)、76.67%(23/30)、94.74%(18/19),可以看出在G3組表達突出(χ_2=11.221,P0.05)有統(tǒng)計學意義;在淺浸潤組和深浸潤組異常表達率分別為55.56%(10/18)和83.72%(36/43)(χ_2=5.428,P0.05),有統(tǒng)計學意義。而其異常表達與臨床分期、年齡、組織學類型、年齡可能無關(P0.05)。2.Wnt3a陽性表達率在正常宮頸組織組10.53%(2/19),CINI組41.67%(5/12),CINII-III組55.56%(10/18),CC組40.98%(25/61),4組比較(χ_2=8.723,P0.05),有統(tǒng)計學意義;在淋巴結轉移組為59.09%(13/22),無淋巴結轉移組30.78%(12/39),(χ_2=4.665,P0.05),有統(tǒng)計學意義。而Wnt3a在臨床分期、病理分級、浸潤深淺、組織學類型、年齡的陽性表達可能無關(P0.05)。3.Lgr5陽性表達率在正常宮頸組織組0%(0/19),CINI組25%(3/12),CINII-III組38.89%(7/18),CC組65.57%(40/61),4組比較(χ_2=28.130,P0.05),有統(tǒng)計學意義。Lgr5在宮頸癌G1 33.33%(4/12)、G2 70%(21/30)、G3 78.95%(15/19)各級的陽性表達有統(tǒng)計學意義(χ_2=7.291);在淺浸潤組和深浸潤組異常表達率分別為38.89%(7/18)和76.74%(33/43)(χ_2=6.149,P0.05),也有統(tǒng)計學意義。而Lgr5在臨床分期、病理分級、浸潤深淺、組織學類型、年齡的陽性表達可能無關(P0.05)。4.在β-catenin和Wnt3a在CC組中共陽性表達23例,共陰性表達13例,兩者之間表達呈正相關(r=0.321);β-catenin和Lgr5在CC組共陽性表達35例,共陰性表達10例,兩者之間表達呈正相關(r=0.387);Wnt3a和Lgr5在CC組共陽性表達13例,共陰性表達9例,兩者之間表達無統(tǒng)計學意義(P0.05)。結論:1.β-catenin、Wnt3a和Lgr5在正常宮頸組織、CINI、CINII-III及CC中,β-catenin的異常表達、Wnt 3a和Lgr5的陽性表達均呈逐漸上升趨勢,提示β-catenin、Wnt3a和Lgr5可能影響宮頸癌的發(fā)生發(fā)展。2.Wn3a可能與宮頸癌前病變的發(fā)生及宮頸癌的轉移有關,β-catenin和Lgr5可能與宮頸癌的惡性程度及侵襲性有關3.Lgr5與β-catenin、Wnt 3a與β-catenin的表達具有一致性,呈正相關,提示Lgr5與Wnt 3a的表達可能激活了wnt信號通路,導致了β-catenin異位至胞質/核內,進而引起細胞異常增生及宮頸癌的發(fā)生。
[Abstract]:Objective: to detect the expression of 尾 -cateninine Wnt3a and Lgr5 in different cervical tissues, and to analyze the relationship between the expression of Wnt3a and Lgr5, and to explore the relationship between the expression of Wnt3a and Lgr5 in the occurrence and development of cervical cancer. Methods: immunohistochemical staining was used to detect the expression of 尾 -cateninine Wnt3a and Lgr5 in different cervical tissues, including 61 cases of cervical carcinoma, 30 cases of cervical intraepithelial neoplasia, 12 cases of CINII-III and 19 cases of normal cervical tissue. Results: 1. 尾 -catenin was expressed in a continuous capsule under normal conditions, but the cell membrane expression was absent in pathological state. The abnormal expression rate of 尾 -catenin in normal cervix tissue group was 5.26 / 119% in normal cervix tissue group and 33.3333 / 12% in CINI group and 38.89% / 12% in CINII-III group (P < 0.05). In CC group, the abnormal expression rates of G1G2G3 were 41.67% and 51.67%, respectively. There were significant differences in abnormal expression in G3 group (蠂 211.221 P 0.05), in shallow infiltrating group and deep infiltrating group were 55.56% 10 / 18 and 83.722% 36 / 43 (蠂 2 / 25.428 P 0.05 P 0.05, respectively). However, the abnormal expression of CINII-III was not correlated with clinical stage, age, histological type and age. 2. The positive rate of Wnt3a expression in normal cervix tissue group was 10.53 / 20% CINI group (41.67%) and CINII-III group (55.56% / 18CC group, 40.98% 25 / 61%) group (蠂 ~ 2T = 8.723 P 0.05). In the lymph node metastasis group, it was 59.09 / 13 / 22, and in the non-lymph node metastasis group 30.78 / 39 / 39 (蠂 ~ 24.665 / P0.05), which was statistically significant. And Wnt3a in clinical stage, pathological grade, invasion depth, histological type, The positive expression of age may not be related to the positive rate of P0.05. 3. The positive expression rate of Lgr5 in normal cervix tissue group was 38.89% CINII-III and 65.5728.130% P0.05 in normal cervical tissue group (蠂 228.130P0.05). There was statistical significance at all levels (蠂 228.130P 0.05). There was statistical significance at all levels (蠂 228.130P0.05, P 0.05). There was statistical significance at all levels (蠂 228.130P0.05, P 0.05). There was statistical significance at all levels (蠂 228.130P0.05, P 0.05). There was statistical significance at all levels of G3 78.951519 in normal cervical tissue group (蠂 228.130P0.05) (蠂 228.130P 0.05). There was statistical significance at all levels (蠂 228.130P 0.05, P 0.05) in CC group (蠂 228.130P 0.05). The abnormal expression rates were 38.89 / 18 and 76.74 / 43 respectively in the deep infiltrating group (蠂 2 + 6.149% P 0.05), which were also statistically significant. However, the positive expression of Lgr5 in clinical stage, pathological grade, depth of invasion, histological type and age may not be related to P0.05. 4. The positive expression of 尾 -catenin and Wnt3a was positive in 23 cases and negative expression in 13 cases in CC group, and the positive expression of 尾 -catenin and Lgr5 was positive in 35 cases and negative expression in 10 cases in CC group, the positive expression of 尾 -catenin and Wnt3a in CC group was positively correlated with that of 尾 -catenin and Wnt3a in CC group. The positive expression of Wnt3a and Lgr5 in CC group was positive in 13 cases and negative in 9 cases. There was no significant difference in the expression of Wnt3a and Lgr5 between the two groups. Conclusion the abnormal expression of 尾 -catenin Wnt3a and Lgr5 in CINII-III and CC of normal cervix tissues showed an increasing tendency of Wnt3a and Lgr5. These results suggest that 尾 -cateninine Wnt3a and Lgr5 may affect the occurrence and development of cervical cancer. 2. Wn3a may be related to the occurrence of precancerous lesions and metastasis of cervical cancer, 尾 -catenin and Lgr5 may be related to the malignancy and invasiveness of cervical carcinoma 3.The expression of Lgr5 and 尾 -catenin WNT 3a and 尾 -catenin may be consistent. The positive correlation suggested that the expression of Lgr5 and Wnt 3a might activate the wnt signaling pathway, leading to 尾 -catenin ectopic into cytoplasm / nucleus, and then to the abnormal proliferation of cells and the occurrence of cervical cancer.
