【摘要】：目的：檢測MUC4、MUC16及HER2在卵巢癌細胞系中的表達情況,探索其與卵巢癌發(fā)生發(fā)展的關(guān)系,及其在卵巢癌早期診斷、治療和預(yù)后監(jiān)測中的作用和意義。 方法：對人卵巢癌SKOV-3細胞株、OVCAR-3細胞株、CAOV-3細胞株進行細胞培養(yǎng)；應(yīng)用RT-PCR技術(shù)檢測人卵巢癌三種細胞中MUC4、MUC16及HER2mRNA水平的表達情況；采用細胞免疫熒光法及Westen Blot法檢測人卵巢癌三種細胞中MUC4、MUC16及HER2蛋白水平的表達情況。 結(jié)果：(1)RT-PCR檢測結(jié)果顯示：MUC4mRNA在人卵巢癌CAOV-3細胞中表達量最高,在OVCAR-3細胞中次之,在SKOV-3細胞中最低,差異無統(tǒng)計學意義(P0.05); MUC16mRNA在人卵巢癌OVCAR-3細胞中表達量最高,在CAOV-3細胞中次之,在SKOV-3細胞中表達量最低,差異具有統(tǒng)計學意義(P0.05); HER2mRNA在人卵巢癌CAOV-3細胞中表達量最高,在OVCAR-3細胞中次之,在SKOV-3細胞中表達量最低,在SKOV-3細胞和OVCAR-3細胞中表達量差異無統(tǒng)計學意義(P0.05),而在SKOV-3細胞和CAOV-3細胞、OVCAR-3細胞和CAOV-3細胞中差異具有統(tǒng)計學意義(P0.05)。 (2)細胞免疫熒光法和Westen Blot法檢測發(fā)現(xiàn)：MUC4蛋白在人卵巢癌SKOV-3細胞和OVCAR-3細胞中不表達,在CAOV-3細胞中有表達；MUC16蛋白在人卵巢癌SKOV-3細胞、OVCAR-3細胞、CAOV-3細胞中均有表達,并且在OVCAR-3細胞中表達最高,在CAOV-3細胞次之,在SKOV-3細胞中表達最低,差異具有統(tǒng)計學意義(P0.05); HER2蛋白在SKOV-3細胞、OVCAR-3細胞和CAOV-3細胞中均有表達,且在CAOV-3細胞中表達最高,在OVCAR-3細胞次之,在SKOV-3細胞中表達最低,差異具有統(tǒng)計學意義(P0.05)。 結(jié)論：(1)MUC4及、MUC16及HER2與卵巢癌的發(fā)生發(fā)展有密切的關(guān)系,并可能成為卵巢癌治療的新靶點。 (2)CA125(MUC16)在早期和晚期卵巢癌中表達水平不同可能與其在不同類型卵巢癌中不表達或低表達有關(guān)。 (3)MUC4、MUC16及HER2在不同卵巢癌細胞系中表達水平不一,MUC4可能單獨或聯(lián)合CA125(MUC16)作為卵巢癌臨床診斷、病情監(jiān)測的輔助實驗室指標。
[Abstract]:Objective: to detect the expression of MUC4, MUC16 and HER2 in ovarian cancer cell lines, and explore their relationship with the occurrence and development of ovarian cancer, and its role and significance in early diagnosis, treatment and prognosis monitoring of ovarian cancer.
Methods: the human ovarian cancer SKOV-3 cell line, OVCAR-3 cell line, CAOV-3 cell line was cultured; three MUC4 cells in human ovarian cancer detection using RT-PCR technology, the expression of MUC16 and HER2mRNA levels; using immunofluorescence method and Westen Blot method to detect three kinds of MUC4 cells in human ovarian carcinoma, the expression of MUC16 the HER2 and protein levels.
Results: (1) RT-PCR test results showed that: MUC4mRNA in human ovarian cancer cell CAOV-3 expression was the highest in OVCAR-3 cells in the second, the lowest in SKOV-3 cells, there was no statistically significant difference (P0.05); MUC16mRNA in human ovarian cancer cell OVCAR-3 expression was the highest in CAOV-3 cells of SKOV-3 expression was the lowest, the difference was statistically significant (P0.05); HER2mRNA in human ovarian cancer cell CAOV-3 expression was the highest in OVCAR-3 cells of the lowest expression in SKOV-3 cells, SKOV-3 cells and OVCAR-3 cells in the expression of the difference was not statistically significant (P0.05), and in SKOV-3 cells and CAOV-3 cells, the difference was statistically significant in OVCAR-3 cells and CAOV-3 cells (P0.05).
(2) to detect cell immunofluorescence method and Westen Blot method: the expression of MUC4 protein in human ovarian cancer SKOV-3 cells and OVCAR-3 cells, are expressed in CAOV-3 cells; MUC16 protein OVCAR-3 in human ovarian cancer SKOV-3 cells, cells were expressed in CAOV-3 cells, and the highest expression in the OVCAR-3 cells in CAOV-3 cells, in SKOV-3 cells was the lowest, the difference was statistically significant (P0.05); HER2 protein in SKOV-3 cells expressed in OVCAR-3 cells and CAOV-3 cells, and expressed in CAOV-3 cells, OVCAR-3 cells in the SKOV-3 cells was the lowest, the difference was statistically significant (P0.05).
Conclusion: (1) MUC4 and MUC16 and HER2 are closely related to the development and development of ovarian cancer, and may be a new target for the treatment of ovarian cancer.
(2) the difference in expression level of CA125 (MUC16) in early and late ovarian cancer may be associated with non expression or low expression in different types of ovarian cancer.
(3) MUC4, MUC16 and HER2 have different expression levels in different ovarian cancer cell lines. MUC4 may be alone or combined with CA125 (MUC16) as an auxiliary laboratory index for ovarian cancer clinical diagnosis and disease surveillance.
