Dissecting Nrf2-dependent HIF1a activation mechanism in arsenic-induced cancer stem-like cells
Long-term exposure to arsenic, esp. the inorganic trivalent arsenic (iAs), a human carcinogen that occurs naturally in the earth's crust or work place due to industrial settings, has been linked to various types of cancers, esp. lung cancer. It has been known for decades that multiple different mechanisms might be involved in iAs-induced malignant transformation. However, whether and how iAs induces cancer stem-like cells (CSCs) from non-stem cells hadn’t been studied. We had previously shown that consecutive treatment of the human bronchial epithelial cells with 0.125 to 0.25 M (~9 to 18ppb) iAs for six months induced generation of the CSCs. In addition to the higher expression of the…
