According to the correlation coefficients, for MCG, the anti-lung-cancer ability significantly correlated with P34 (batatasin III), P12 (2-isobutylmalic acid), P6 (gastrodin), P42 (coelonin), P15 (coelovirin B), P35 (2,7-dihydroxy-1-(4-hydroxybenzyl)-4-methoxyphenanthrene), P25 (gymnoside III), and P41 (monbarbatain A), etc., in a positive way. This evidence concerns the gene PPIB and lung cancer.
