Fasting may help protect against immune-related effects of chemotherapy and aging
Chemotherapy can cause many side effects, including the depletion of immune cells. Even in the absence of chemotherapy, normal aging takes a heavy toll on the immune system. Now researchers have found that a simple dietary intervention -- periodic fasting -- may combat both chemotherapy-induced and aging-related changes in immune cell function by replenishing stem cells in the blood. The findings suggest that fasting may provide benefits for cancer patients, the elderly, and people with immune defects.

Fasting triggers stem cell regeneration of damaged, old immune system
In the first evidence of a natural intervention triggering stem cell-based regeneration of an organ or system, a study in the June 5 issue of the Cell Press journal Cell Stem Cell shows that cycles of prolonged fasting not only protect against immune system damage -- a major side effect of chemotherapy -- but also induce immune system regeneration, shifting stem cells from a dormant state to a state of self-renewal.

Scientists generate long-sought molecular map of critical genetic machinery
A team led by researchers at The Scripps Research Institute has used advanced electron microscopy techniques to determine the first accurate structural map of Mediator, one of the largest and most complex 'molecular machines' in cells. The mapping of its structure -- which includes more than two dozen unique protein subunits--represents a significant advance in basic cell biology and should shed light on medical conditions involving Mediator's dysfunction, from cancer to inherited developmental disorders.

Our own treacherous immune genes can cause cancer after viral infection
Mutations that cause cancer following HPV, human papillomavirus, infection are caused by a family of genes that normally protect against viral infections, finds new UCL research. This raises the possibility of developing drugs that block the activity of these genes to prevent HPV-associated cancers from developing and reduce the ability of existing cancers to evolve resistance to treatments.

Research helps clarify how obesity leads to type 2 diabetes, cancer
In a study published online June 5 in the journal Cell, a researcher at The University of Texas at Dallas and colleagues at the University of California, San Diego found that a protein called HIF-1 alpha plays a key role in the development of insulin resistance and type 2 diabetes in obese mice. The findings may also shed light on the connection between obesity and cancer.

Four new genes confirmed to increase familial breast cancer risk
Four new genes have been added to the growing list of those known to cause increased breast cancer risk when mutated through the efforts of researchers at Huntsman Cancer Institute at the University of Utah, who lead an international consortium working to find more gene mutations that cause inherited breast cancer susceptibilities.

New diagnostic imaging techniques deemed safe in simulations
Gamma and neutron imaging offer possible improvements over existing techniques such as X-ray or CT, but their safety is not yet fully understood. Using computer simulations, imaging the liver and breast with gamma or neutron radiation was found to be safe, delivering levels of radiation on par with conventional medical imaging, according to researchers at Duke Medicine.

Weight loss surgery also safeguards obese people against cancer
Weight loss surgery might have more value than simply helping morbidly obese people to shed unhealthy extra pounds. It reduces their risk of cancer to rates almost similar to those of people of normal weight. This is the conclusion of the first comprehensive review article taking into account relevant studies about obesity, cancer rates and a weight loss procedure called bariatric surgery. Published in Springer's journal Obesity Surgery, the review was led by Daniela Casagrande.

'Liquid biopsy' offers new way to track lung cancer
Research carried out at Cancer Research UK's Manchester Institute, based at The University of Manchester -- part of the Manchester Cancer Research Centre -- has looked at the potential of using circulating tumor cells -- cells that have broken off from the tumor and are circulating in the blood -- to investigate a patient's disease in a minimally invasive manner.

Tumor chromosomal translocations reproduced for the first time in human cells
Scientists from the Spanish National Cancer Research Centre and the Spanish National Cardiovascular Research Centre have been able to reproduce, for the first time in human cells, chromosomal translocations associated with two types of cancer: acute myeloid leukemia and Ewing's sarcoma. The discovery, published today in the journal Nature Communications, opens the door to the development of new therapeutic targets to fight these types of cancer.

Screening has prevented half a million colorectal cancers
An estimated half a million cancers were prevented by colorectal cancer screening in the United States from 1976 to 2009, report researchers from the Cancer Outcomes, Public Policy, and Effectiveness Research Center at Yale Cancer Center. Their study appears in the journal Cancer. During this more than 30-year time span, as increasing numbers of men and women underwent cancer screening tests -- including fecal occult blood testing, sigmoidoscopies, and colonoscopies -- colorectal cancer rates declined significantly, the researchers found.

New device isolates most aggressive cancer cells
Not all cancer cells are created equal -- some stay put in the primary tumor, while others move and invade elsewhere. A major goal for cancer research is predicting which cells will metastasize, and why. A Cornell cancer research team is taking a new approach to screening for these dangerous cells, using a microfluidic device they invented that isolates only the most aggressive, metastatic cells.

Lasers and night-vision technology help improve imaging of hidden lymphatic system
Detecting lymphedema early, before swelling occurs, would lead to better outcomes for patients, but the major barrier preventing early diagnosis is the lack of high-resolution imaging techniques that can resolve these tiny vessels. Recently, a team of researchers at UTHealth Medical School has developed a new technology that can non-invasively image the human lymphatic system. A fluorescent dye and commercially-available laser diode and military-grade night vision devices are used to visualize the lymphatic capillaries.

Stopping the spread of breast cancer
Scientists have discovered a new pathway that can stop breast cancer cells from spreading. Working with human cancer cells and a mouse model of breast cancer, scientists identified a new protein that plays a key role in reprogramming cancer cells to migrate and invade other organs. When that protein is removed from cancer cells in mice, the ability of the cells to metastasize to the lung is dramatically decreased.
