Objective:To investigate the genes that were differentially expressed between clear cell carcinoma (CCC) and serous carcinoma (SAC) of the ovary with complementary DNA microarray.Methods:Complementary DNA microarray was carried out in 8 CCCs and 8 SACs of the ovary. Differentially expressed genes were identified and verified by real-time polymerase chain reaction. The expression of the protein was also verified with immunohistochemistry and Western blot in cells and tissues of ovarian CCC.Results:Comparison of the gene expression profiling identified 21 genes with more than 2-fold different expression between CCC and SAC of the ovary. The up-regulated and down-regulated genes were 9 and 12, respectively. The verification of Annexin IV in the cell line and tissues was in accordance with the result of the microarray.Conclusions:The complementary DNA microarray technique is a feasible way to explore the difference of the gene expression profiling between the 2 types of ovarian carcinoma. The overexpression of Annexin IV may be an ovarian CCC-specific molecular marker.Abbreviations:CCC- clear cell carcinoma, SAC- serous carcinoma, PCR- polymerase chain reaction, RT-PCR- reverse transcriptase PCR, ABCF2- ATP-binding cassette, sub-family F- member 2, HNF-1b- hepatocyte nuclear factor 1β

Abstract Background Ovarian clear cell carcinoma (OCCC) is the second subtype of ovarian epithelial carcinoma reported to be closely related to Lynch syndrome (LS). ARID1A mutation is an important pathogenetic mechanism in OCCC that leads to loss of ARID1A expression in approximately half of OCCCs. However, the correlation of MMR status and ARID1A deficiency is unclear. The current study aimed to identify the clinical and histopathological characteristics of OCCC associated with dMMR and to further explore the association between dMMR and ARID1A deficiency. Methods A cohort of 176 primary OCCC patients was enrolled and review included histological characteristics (nuclear atypia, necrosis, mitosis, stromal hyalinization, and background precursors) and host inflammatory response (tumor-infiltrating lymphocytes, peritumoral lymphocytes, intratumoral stromal inflammation and plasma cell infiltration). Immunohistochemical staining of MLH1, PMS2, MSH2, MSH6 and ARID1A was performed using tissue microarrays. Results dMMR was detected in 10/176 tumors (6 %), followed by MSH2/MSH6 (6/176), MLH1/PMS2 (3/176), and MSH6 (1/176). The average age of patients with dMMR was younger than that of patients with intact MMR (46 y vs. 53 y). Tumors with diffuse intratumoral stromal inflammation remained significantly associated after multivariate analysis. ARID1A expression was absent in 8 patients with dMMR (8/10), which is a significantly higher frequency than that observed in patients with intact MMR (80 % vs. 43.2 %). Conclusions Our study indicates that diffuse intratumoral stromal inflammation of OCCCs is associated with dMMR, with loss of MSH2/MSH6 expression being most frequent. dMMR is strongly associated with the loss of ARID1A expression in OCCC.
