levels of c-myc mrna are also elevated in the peripheral region of the lens epithelium , which contains cells undergoing differentiation in vivo , suggesting that the regulation of c-myc mrna which occurs in vitro may also occur in vivo . c-myc mrna , c-fos mrna , and c-src mrna showed distinct patterns of regulation associated with lens fiber formation in vivo , thus providing evidence that the regulation of c-myc mrna is specific to this proto-oncogene .
