Moreover, through the phosphoinositide 3‐kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) pathway, deoxyshikonin induces apoptosis and cell arrest in the G0/G1 cell cycle in human colorectal cancer HT29 cells and suppresses tumour growth in xenograft mice transplanted with human colorectal cancer DLD‐1 cells.22 This evidence concerns the gene MTOR and neoplasm.
