Lewis lung carcinoma

Lewis lung carcinoma is a tumor 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.[1] It is also called 3LL and LLC and is used as a transplantable malignancy. It has been used in many studies.[2]

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[3] Cannabinoids increase the life span of mice carrying Lewis lung tumors and decrease primary tumor size.[4] There are multiple modes of action.[5]
