For instance, YAP1‐induced tumor necrosis factor α (TNF‐α) expression promotes myeloid‐derived suppressor cells and impedes cytotoxic T‐cell infiltration in ovarian carcinomas.[31] On the other hand, several studies showed that YAP1 inhibited effector T‐cell differentiation by acting as an internal factor. This evidence concerns the gene YAP1 and ovarian carcinoma.
