PIEZO1 and ovarian serous cystadenocarcinoma: PIEZO1 protein levels were significantly higher in KIRC (p < 0.001), GBM (p < 0.0001), HNSC (p < 0.0001) and PAAD (p < 0.0001) and significantly lower in COAD (p < 0.05), LIHC (p < 0.0001), LUAD (p < 0.0001), ovarian serous cystadenocarcinoma (OV) (p < 0.0001) and UCEC (p < 0.05) (Figure 1(c)).
