- According to the World Health Organization (WHO), cancer is the second most common cause of death worldwide, accounting for more than 8 million deaths. The number of diagnosed cases is expected to increase from 14 million (in 2012) to 22 million annually in 20 years.
Resistance to chemotherapy, cancer recurrence and metastasis are common clinical problems for patients suffering from cancer. A hypothesis is that these are caused by a small population of cells within a tumor, so-called cancer stem cells (CSCs) which are also believed to drive tumorigenesis. Current anticancer therapies are based on their ability to shrink tumors, leaving the population of CSCs largely untouched. This means that such therapies may fail, because they leave...

The number of diagnosed cases is expected to increase from 14 million (in 2012) to 22 million annually in 20 years.
Resistance to chemotherapy, cancer recurrence and metastasis are common clinical problems for patients suffering from cancer. A hypothesis is that these are caused by a small population of cells within a tumor, so-called cancer stem cells (CSCs) which are also believed to drive tumorigenesis. Current anticancer therapies are based on their ability to shrink tumors, leaving the population of CSCs largely untouched. This means that such therapies may fail, because they leave the cells that can regenerate and spread the tumor. Novel anticancer therapies aim to target also CSCs. Combined with currently used drugs such treatments could lead to cancer regression.
Studies performed in 2009 by Gupta and co-workers showed that salinomycin, a polyether antibiotic commonly used in veterinary medicine, was the most efficient out of 16000 compounds to decrease the population of cells with stem-like properties. The mechanism of action for this compound still remains unknown. We aimed towards the attachment of a suitable fluorescent probe to the salinomycin core structure, which would result in a new derivative that is visible in fluorescence microscopes. This would allow localizing SA in
cells and would provide useful information in explaining the molecular mode of action of SA against CSCs. (Less)
