NOTCH1 and prostate cancer: Notch signaling pathway amplification or activating mutations played vital roles in the progression and evolution of cancers, including leukemia [26], prostate cancer [27], ovarian cancer [28], colorectal carcinoma [29,30], and breast cancer [31], etc. Our current results indicated significant elevations of Notch1/2 mRNA in peripheral bloods and GC tissues, which were consistent with previous studies [17].
