KDM7A and cancer: We previously reported that histone demethylase Jumonji C domain containing histone demethylase 1 homolog D (JHDM1D, also known as KDM7A) was highly induced in cancer cells under nutrient starvation and decreased tumor growth by regulating tumor angiogenesis (11); however, the specific lncRNAs potentially involved in angiogenesis under nutrient starvation stress are largely unknown.
