Support for MC Cable

[gold7278]

I was recently told that MC cable should be supported no more than every four feet. I've always been told in the past, support for MC cable is between 5 and 6 feet.Can someone please confirm which is correct and post the corresponding article from the code which states proper distance. Thank you.
