DescriptionA cancer diagnosis is an event that countless people fear. Besides the debilitating effects of the disease itself, treatments also take a substantial toll on a patient’s health as well as their finances. Even successful treatments cause survivors to live with the constant concern that their illness will return. When relapse does occur, prior therapies may no longer be an option due to cancer cells gaining resistance under the cancer stem cell model. As such, new therapies must be developed to once again aid patients enter a second battle for their lives.
Phytochemicals, for example curcumin, are plant derived molecules that have shown promise as a potential treatment for ovarian and other cancers. In addition to phytochemicals, repurposed FDA approved drugs are another option being explored by researchers. Studying drugs that are already approved for other indications will reduce the time and cost required to develop new therapies. For people living with limited access to medical care due to financial matters, low cost treatment for deadly diseases is highly desired.
By conducting a series of in vitro alamarBlue cell viability assays, this paper aims to provide evidence that niclosamide, an off patent FDA approved drug for parasitic tapeworm infection, and curcumin, a phytochemical derived from turmeric, hold the potential to be low cost therapies for women suffering from ovarian cancer. In addition, using these molecules in combination has shown synergistic properties that act to decrease cell viability of SKOV3 ovarian cancer cells. Under the cancer stem cell model, cases of relapse may be reduced by using niclosamide and curcumin to target resistant subpopulations of cancer cells left after conventional therapies are administered.
