Advance in resistance mechanism of cancer stem cells therapy / 药学实践杂志

ABSTRACT

Lung cancer is the leading cause of cancer deaths worldwide.Recurrence and metastasis are the primary reasons for its poor prognosis.Growing evidence has proposed that lung cancer may be driven by cancer stem cells (CSCs), which may be responsible for the poor outcome of lung cancer.The resistance mechanisms of cancer stem cells include four aspects high expression of the chemo-resistant efflux transporter ABC in CSCs populations, over-expression of ALDH, efficient DNA damage repair system, developmental pathway activation.The tolerance mechanism of CSCs was described to provide theoretical basis for clinical treatment and development of new anti-tumor drugs.
