Project description:Difference expression analyses before and after human fucosyltransferase gene 1 transfection into ovarian cancer clear cell line (Human cancer array)
Project description:75% ovarian epithelial tumor overexpresses Lewis y antigen, which notably strenthen such malignant biological behaviors as metastasis, drug resistance and proliferation. The key enzyme of Lewis y synthesis is human fucosyltransferase gene 1(hfut1). Through transfecting hfut1 into Lewis y low expressing cell line RMG-I, we got a pair of cell lines. We hypothesized that Lewis y antigen plays a major role in ovarian canceration . Using gene arrays, we comprehensively profiled mRNA differential expression between fut1-pretransfected and posttransfected clear cell of human epithelial OvCa. We expected that over-expression of lewis y antigen would lead to higher expression of genes associated with growth, metastasis,proliferation and so on. we established ovarian tumor cell line RMG-I-H by stably transfecting human fucosyltransferase gene 1 into cell line RMG-I. RMG-I-H overexpresses Lewis y antigen, which is known as a cancer-related tetrasaccharide antigen. We profiled for gene expression both cells pretransfected and posttransfected.

Project description:Exogenous signals from drug-stressed cancer cells promote acquisition of a more aggressive phenotype of neighboring tumor cells. To identify extracellular signaling molecules that potentially contribute to the development of therapy resistance, we examined how cancer cell secretome changes in response to chemotherapy. We performed LC-MS/MS analysis of secretomes from several ovarian cancer cell lines representing different tumor subtypes: serous ovarian cancer cell line (OVCAR3), ovarian cystadenocarcinoma cell line (MESOV) and clear cell ovarian cancer primary culture isolated from ascites (cells 26) before and 48 hours after cisplatin treatment. In addition, we studied secretomes from keratinocyte-derived epithelial cell line HaCaT as non-cancerous “normal” cells. Functional annotation of proteins which secretion increased after cisplatin showed that these proteins were mainly associated with cluster of spliceosome.
Project description:ARID1A, which encodes a component of the SWI/SNF chromatin-remodeling complex, is commonly mutated in ovarian clear cell carcinoma and many other cancer types. We used label-free LC-MS/MS to identify ARID1A-dependent proteome changes in ovarian clear cell carcinoma cell lines. In our first analysis, we compared ARID1A-wildtype ovarian clear cell carcinoma cell line OVCA429 with or without ARID1A CRISPR knockout. In a complementary analysis, we compared ARID1A-mutated ovarian clear cell carcinoma cell line OVISE with or without ARID1A overexpression using a tet-inducible promoter.
