TLR4 and ovarian carcinoma: In the second experiment, we observed a weak positive correlation between TLR4 and PAUF mRNA expression using the PC cell data from the CCLE database (n = 52, r = 0.363, p = 0.008), a similar correlation was reported in ovarian cancer patients at the protein level (n = 182, r = 0.256, p = 0.001) [5].
