CDH1 and cancer: Methods: Since in vitro 3D spheroidgenesis is thought to reflect at least some of the in vivo aspects of cancer biology (which undoubtedly involve cell adhesion, metabolism, and hypoxia-related pathways) and since we previously investigated these pathways in a model of spontaneous spheroidgenesis, this present study investigates these pathways in a model of induced spheroidgenesis with comparative studies involving a series of well-known E-cadherin-positive (MCF-7, HTB-126, HTB-27) and E-cadherin-negative (MDA-MB-468, MDA-MB-231, BT-549) human breast carcinoma cell lines.
