OXTR and invasive ductal breast carcinoma: The OTR gene expression was significantly higher in normal breast tissues than in breast tumour tissues in 7 out of 10 datasets (Figure 1B), including GSE21422 (p = 0.0434, normal vs. invasive ductal carcinomas), GSE7904 (p < 0.0001, normal vs. tumour), GSE10810 (p = 0.0007, normal vs. tumour), GSE31448 (p = 0.0003, normal vs. tumour), GSE10780 (p < 0.0001, normal vs. tumour), GSE20711 (p = 0.0010, normal vs. tumour), and GSE3744 (p < 0.0001, normal vs. tumour).
