KCNE1 and uterine cancer: The apoptotic influence of KCNE1 in U87-MG cells is proposed to occur through canonical K+ efflux through Kv7.1, inducing decreased cytoplasmic K+, a known apoptotic trigger [160,162], whereas KCNE1 induces uterine cancer cell proliferation via modulation of HERG channels [158,163].
