Conditions for hypoxia / reoxygenation cycles were optimized using two human
metastatic breast cancer cell lines (MDA - MB 231 and BCM2).
In our study, we found that exposing
metastatic breast cancer cell lines to hypoxia and reoxygenation cycles induces a unique subpopulation that is highly metastatic and exhibits stem - like and EMT phenotypes.
Here, we show that a non-adherent, stem - like, and metastatic CSC - enriched subpopulation could be isolated by exposing human
metastatic breast cancer cell lines to cycles of chronic hypoxia followed by reoxygenation.

To study the effect of hypoxia / reoxygenation cycles on
breast cancer, we exposed two
metastatic human
breast cancer cell lines (MDA - MB 231 and BCM2) to cycles of chronic hypoxia and nutrient deprivation.
Breast cancer cell lines contain functional
cancer stem
cells with
metastatic capacity and a distinct molecular signature.
LARP7 was expressed at relatively high levels in the untransformed mammary epithelial
cell lines (MCF10A and EpH4) and noninvasive
breast cancer cell lines (MCF7, BT474, T74D, and ZR75B), but was markedly reduced in all four invasive and
metastatic cancer lines examined (MDA - MB - 468, BT549, MDA - MB - 231, and MDA - MB - 435; Figure 1D).
