KRAS and non-small cell lung carcinoma: The aim of this study is to establish a mini profile with three different cancer lines (the Kras mutant cell lines: non-small cell lung carcinoma A549 and human colon carcinoma LoVo, and the Kras wild-type cell line: human breast cancer SK-BR-3) to quantitatively and functionally evaluate the apoptotic effect with different doses of propofol, and thereby determine whether propofol might be advantageous as an anesthetic for surgeries of certain cancers.
