TY - JOUR AU - Sun Xiao-xiao AU - Yu Qiang PY - 2017 TI - Intra-tumor heterogeneity of cancer cells and its implications for cancer treatment JF - Acta Pharmacologica Sinica; Vol 36, No 10 (October 2015): Acta Pharmacologica Sinica(Special Feature:Cancer Precision Medicineļ¼‰ Y2 - 2017 KW - N2 - Recent studies have revealed extensive genetic and non-genetic variation across different geographical regions of a tumor or throughout different stages of tumor progression, which is referred to as intra-tumor heterogeneity. Several causes contribute to this phenomenon, including genomic instability, epigenetic alteration, plastic gene expression, signal transduction, and microenvironmental differences. These variables may affect key signaling pathways that regulate cancer cell growth, drive phenotypic diversity, and pose challenges to cancer treatment. Understanding the mechanisms underlying this heterogeneity will support the development of effective therapeutic strategies. UR - http://www.chinaphar.com/article/view/9207
