In 1975, Munson discovered that cannabinoids suppress Lewis lung carcinoma cell growth. The mechanism of this action was shown to be inhibition of DNA synthesis[1]Cannabinoids increase the life span of mice carrying Lewis lung tumors and decrease primary tumor size.[2] There are multiple modes of action.[3]
A carcinoma discovered by Dr. Margaret R. Lewis of the Wistar Institute in 1951. This tumor originated spontaneously as a carcinoma of the lung of a C57BL mouse. The tumor does not appear to be grossly hemorrhagic and the majority of the tumor tissue is a semifirm homogeneous mass.[4] It is also called 3LL and LLC and is used as a transplantable malignancy.
It has been used in many studies.[5]
