Cancer Research:GMO pink pineapples help prevent cancer ♦ Anticancer drug can spur immune system ♦ Combining magnetism and light to fight cancer

GMO pink pineapples could help prevent cancer Cancer-fighting pink pineapples, heart-healthy purple tomatoes and less fatty vegetable oils may someday be on grocery shelves alongside more traditional products. These genetically engineered foods could receive government approval in the coming years.
Old cancer drug could have new use in fighting cancer  An old cancer drug can not only kill cancer cells, but also works to change how certain cancer cells function, weakening those cells so they can be killed by other drugs.
Anticancer drug can spur immune system to fight infection Imatinib, an example of a 'targeted therapy' against cancer, or related drugs might be tools to fight a variety of infections, scientists say. Imatinib, is an example of a "targeted therapy" against certain types of cancer. It blocks tyrosine kinase enzymes, which are dysregulated in cancers such as chronic myelogenous leukemia and gastrointestinal stromal tumors.
Combining magnetism and light to fight cancer By combining, in a liposome, magnetic nanoparticles and photosensitizers that are simultaneously and remotely activated by external physical stimuli (a magnetic field and light), scientists obtained total tumor regression in mice. Non-toxic when they are not activated, such therapies can also achieve a reduction in adverse effects.
Expanding on liquid biopsies with exosomes A new type of liquid biopsy for solid tumors based on analyzing exosomes from the blood is being tested by clinicians. "The term 'liquid biopsy' describes the fact that a simple blood sample can contain many tumor-derived molecules and even tumor cells, enabling molecular analyses similar to those possible in tumor tissue samples,"
