After filtering for GS and MM value, we eventually obtained 36 hub genes (Loc100041932, 1300001i01rik, Kdelr2, Lasp1, 1110005a03rik, Llgl2, Copa, Orai1, Bcar1, Actn4, Col4a2, Jmjd5, Arrb1, Cry2, Gtf2b, Tmem64, Zfp319, Myadm, Sparc, Ehmt1, Ctgf, Litaf, Psmc6, Sms, Ckmt1, Oat, Zyx, Col18a1, Cox17, Enpp5, Prickle1, Pck2, Slc44a4, Ppap2b, Fn1, and Tpp1) and their expression were significant in distinguishing PHY906-CPT11 and other treatments for colon cancers. The gene discussed is COL18A1; the disease is malignant colon neoplasm.
