Radiation therapy is part of the treatment regimen for about two thirds of cancer patients today. Radiotherapy is well tolerated in most cases, but it can also lead to damage in healthy tissues that are also irradiated. One debilitating side effect is radiation-induced fibrosis. Fibrosis is a process of scarring by which healthy tissue is...

Scientists find surprising impact of junk DNA and RNA in cancer
Killer T cells surround a cancer cell. “Human satellite II,” an exceptionally high-copy but unexplored sequence of the human genome thought of as “junk DNA,” has a surprising ability to impact master regulators of our genome, and it goes awry in 50 percent of tumors, according to a new study published in Cell Reports by scientists...

Cancer Is Partly Caused By Bad Luck, Study Finds
Nearly two-thirds of cell mutations that cause cancer are caused by random error, a study found. Cancer can be caused by tobacco smoke or by an inherited trait, but new research finds that most of the mutations that lead to cancer crop up naturally. The authors of the study published Thursday poked a hornet’s nest by suggesting...

Scientific discovery opens new possibilities for cancer and fibrosis treatment
Researchers from the Turku Centre for Biotechnology (BTK) in Finland have discovered that a cellular fuel sensor, known to control energy processes in the cells, is involved in the regulation of the contact of cells with their surrounding environment. This unexpected link could help scientists better understand life-threatening diseases, such as cancer and tissue fibrosis....

Ever wondered why exercise reduces the risk of CANCER? Scientists say active people are better at removing a by-product that fuels tumours
Exercising helps the body get used to the cancer-causing by-product lactate Study finds lactate plays a key role in developing and spreading cancer University of Colorado research paves the way for new cancer treatments It’s long been known that exercising can reduce the risk of cancer. And now scientists believe they have found another reason why...

The researchers discovered an unexpected link between cancer and autism
SHANK regulates adhesion and protrusion in very different cell types: cancer cells and neurons. Image taken by Dr Guillaume Jacquemet reveals the distinct morphologies of neurons and cancer cells. On the right: Primary Rat hippocampal …more Researchers from Turku Centre for Biotechnology have observed that a protein called SHANK prevents the spread of breast cancer...

Leukemia drug fends off cancer for a decade, study shows
The cancer drug Gleevec The cancer drug Gleevec appears to keep chronic myeloid leukemia at bay a decade into treatment — with no signs of additional safety risks, a new study finds. Gleevec — known generically as imatinib — was hailed as a “wonder drug” when it was introduced in 2001 for treating chronic myeloid leukemia (CML)....

Scientists stimulate immune system, stop cancer growth
Increasing expression of a chemical cytokine called LIGHT in mice with colon cancer activated the immune system’s natural cancer-killing T-cells and caused primary tumors and metastatic tumors in the liver to shrink. A chemical found in tumors may help stop tumor growth, according to a new study. Researchers at the University of Illinois at Chicago...

The intestine has a reservoir of stem cells that are resistant to chemotherapy
These comprise a small group of passive stem cells -quiescent- that are activated when needed and have the capacity to produce any kind of intestinal cell. Quiescent cells are relevant for tissue regeneration and for participation in tumor development After Chemotherapy, these cells change their behaviour, become active and regenerate all cell types in the...

Cancer breakthrough: Scientists discover how to kill ‘undruggable’ proteins using ‘the kiss of death’
Many cancers and Huntington’s are caused by stubborn proteins Ras and Myc No previous studies have been able to kill the ‘undruggable’ proteins A team at the University of Dundee forced molecules to bind to Ras and Myc In doing so, they successfully destroyed them – paving the way to a cure Scientists have discovered...
