Most drugs used to treat lung, breast and pancreatic cancers also promote drug-resistance and ultimately spur tumor growth. Researchers at the University of California, San Diego School of Medicine have discovered a molecule, or biomarker, called CD61 on the surface of drug-resistant tumors that appears responsible for inducing tumor metastasis by enhancing the stem cell-like properties of cancer cells.

The cancer protein KRas is a factor in the development of several types of cancer. Mutated KRas, for example, can be found in a large number of all tumour cells in patients with pancreatic cancer. It sits on the inner leaflet of the cell membrane and relays signals into the cell’s interior. Scientists at the Max Planck Institute of Molecular Physiology in Dortmund have now discovered why KRas is almost exclusively found at the cell membrane when observed under the microscope.

Researchers at the University of California, San Diego School of Medicine have found that too little or too much of an enzyme called SRPK1 promotes cancer by disrupting a regulatory event critical for many fundamental cellular processes, including proliferation.

A team of researchers from five Swedish universities, led by Karolinska Institutet and the Science for Life Laboratory, have identified a new way of treating cancer. The concept is presented in the journal  Nature  and is based on inhibiting a specific enzyme called MTH1, which cancer cells, unlike normal cells, require for survival. Without this enzyme, oxidized nucleotides are incorporated into DNA, resulting in lethal DNA double-strand breaks in cancer cells.

Researchers at Karolinska Institutet have discovered that a substance called Vacquinol-1 makes cells from glioblastoma, the most aggressive type of brain tumor, literally explode. When mice were given the substance, which can be given in tablet form, tumor growth was reversed and survival was prolonged. The findings are published in the journal Cell.

In a study published in Nature Communications, researchers at Karolinska Institutet and Uppsala University in Sweden present a new drug candidate, which selectively kills dormant cells within a cancer tumor through starvation. These tumor cells, which are found in less oxygenated parts of solid tumors, are resistant to conventional treatments.
