ABSTRACT: 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:To identify the gene signature accounting for the distinct clinical outcomes in ovarian clear cell cancer patients Clear cell ovarian cancer is an epithelial ovarian cancer histotype that is less responsive to chemotherapy and carries poorer prognosis than serous and endometrioid histotypes. Despite this, patients with these tumors are treated in a similar fashion as all other ovarian cancers. Previous genomic analysis has suggested that clear cell cancers represent a unique tumor subtype. Here we generated the first whole genomic expression profiling using epithelial component of clear cell ovarian cancers and normal ovarian surface specimens isolated by laser capture microdissection. Arrays analyzed using BRB ArrayTools and PathwayStudio software was used to identify the signaling pathways. Gene expression profiling was completed for 10 clear cell ovarian cancer specimens and 10 normal ovarian surface epithelium using the Affymetrix human U133 Plus 2.0 Arrays
