Background: Recent evidence suggests that epithelial cancers, including colorectal cancer are driven by a small sub-population of self-renewing, multi-potent cells termed cancer stem cells (CSCs) which are thought to be responsible for recurrence of cancer. One of the characteristics of CSCs is their ability to form floating spheroids under(More)
We observed a co-upregulation of the insulin-like growth factor receptor (IGF-1R)/AKT/mammalian target of rapamycin (mTOR) [InAT] axis and the mevalonate-isoprenoid biosynthesis (MIB) pathways in colorectal cancer stem cells (CSCs) in an unbiased approach. Hence, we hypothesized that the InAT axis might regulate the MIB pathway to govern colorectal CSCs(More)

Abstract Background: Recent evidence suggests that epithelial cancers, including colorectal cancer are driven by a small sub-population of self-renewing, multi-potent cells termed cancer stem cells (CSCs) which are thought to be(More)
Selective targeting of cancer stem-like cells (CSCs) is a paradigm-shifting approach. We hypothesized that CSCs can be targeted by interfering with functions of sulfated glycosaminoglycans, which play key roles in cancer cell growth, invasion and metastasis. We developed a tandem, dual screen strategy involving (1) assessing inhibition of monolayer versus(More)
