NOTCH1 and endometrial cancer: The microarray analysis also showed that the common genes for the tissue and blood samples (−3.0 < FC > 3.0) were G1 vs. C: TGFβ1 (Transforming growth factor isoform 1), WNT5A (vimentin 5A), TGFβ2 (transforming growth factor isoform 2), and NOTCH1; G2 vs. C: BCL2L, SOX9, BAMBI (bone morphogenic protein and activin membrane-bound inhibitor), and SMAD4; G3 vs. C: STAT1 and TGFBβ1. Additionally, mRNA TGFβ1, NOTCH1, and BCL2L are all common for all grades of endometrial cancer (Table 5; p < 0.05).
