Plasma membrane calcium ATPase 4 and the remodeling of calcium homeostasis in human colon cancer cells.

abstract：:Compounds of nickel(II) and cadmium(II) are carcinogenic to humans and to experimental animals. One frequently discussed mechanism involved in tumor formation is an increase in reactive oxygen species by both metals with the subsequent generation of oxidative DNA damage. In the present study we used human HeLa cells t...
