9^8 METABOLISM OF THE CANCER CELL 12 



tions in deoxyribonucleoprotein are no longer under the control of normal extra- 

 cellular factors that regulate cellular division. Also, the possibility exists that the 

 tumor cell has elaborated new factors which are responsible for the unrestrained 

 growth. The further elucidation of the mechanism which regulates mobilization 

 of the nucleic acids and proteins associated with mitotic activity may be of more 

 importance to the understanding of malignant behavior than metabolism per se.
