We first studied the expression patterns of TSLP isoforms in ovarian cancer by examining the TSLP transcript variants with RT-PCR in 5 non-malignant immortalised human ovarian surface epithelial (IOSE) cell lines, 2 non-malignant immortalised human fallopian tube secretory epithelial cell (FTSEC) lines and 16 human ovarian cancer cell lines. Here, TSLP is linked to ovarian cancer.
