Differences in certain pathways, such as TNF or ERBB (for liver hepatocellular carcinoma and prostate adenocarcinoma), EGFR or Wnt (for lung squamous cell carcinoma), JAK-STAT (for kidney renal clear cell carcinoma), NFkB (for breast invasive carcinoma) and TGFβ, mTOR or NFkB (for stomach adenocarcinoma) were noted between tumor and normal tissue. The gene discussed is MTOR; the disease is invasive breast carcinoma.
