For the following genes, we found no significant changes in expression in fibroblasts after treatment with exosomes from ovarian cancer cells: HTATIP2 (HIV-1 Tat interactive protein 2, 30 kDa), IL1B, TGFB1 and TNFSF10 (TRAIL, Tumor necrosis factor (ligand) superfamily, member 10). Here, TNF is linked to ovarian cancer.
