Opening the door to the cause of myeloid leukemia: Finding the targets of common mutation
Researchers at the University of Birmingham have made a breakthrough in understanding how mutated genes in leukemia reprogram blood stem cells and send them spiraling out of control.

Targeting the strain of bacteria that causes ulcers may help prevent stomach cancer
A new review published in the Cochrane Library, indicates that eradicating Helicobacter pylori bacterium -- the main cause of stomach ulcers -- with a short course of therapy comprising two commonly used medicines may help to reduce the risk of gastric cancer.

Additional radiation reduces breast-cancer recurrence for some patients: Hamilton study
A study has found no increase in overall survival but a reduction in breast cancer recurrence when additional radiation is given to the lymph nodes as well as the standard treatment of whole-breast irradiation after breast-conserving surgery. The research, which examined the addition of regional nodal irradiation to whole-breast irradiation compared with whole-breast irradiation alone, was published July 22 in the prestigious New England Journal of Medicine.

New research from Lawson uncovers important molecule in ovarian cancer
Scientists at Lawson Health Research Institute have uncovered an important new target for ovarian cancer therapy. Contrary to current research this new study found that LKB1 is an important molecule in the cancer's promotion and survival. Their research definitively shows that ovarian cancer cells still have LKB1 and that this molecule allows ovarian cancer spheroids to change their metabolism, promote tumor cell survival and make them more resistant to chemotherapy.

Modified DNA building blocks are cancer's Achilles heel
In studying how cells recycle the building blocks of DNA, Ludwig Cancer Research scientists have discovered a potential therapeutic strategy for cancer. They found that normal cells have highly selective mechanisms to ensure that nucleosides -- the chemical blocks used to make new strands of DNA -- don't carry extra, unwanted chemical changes. But the scientists also found that some types of cancer cells aren't so selective.

Poor survival in multiple myeloma patients linked to genetic variation
Researchers have found that multiple myeloma patients with a genetic variation in the gene FOPNL die on average 1-3 years sooner than patients without it. The finding was identified with a genetic mapping technique, genome wide association studies, and verified in patient populations from North America and Europe. Published in Nature Communications, this was the first study to survey the entire human genome for genetic variation influencing survival, and is a first step toward applying precision medicine to multiple myeloma.

New 'TripAdvisor' site to address use of substandard biomedical research tools
An international panel of leading scientists is launching a new TripAdvisor-style website aimed at helping researchers choose better-quality research tools - and avoiding potentially serious errors in biomedical research. In a 'call to action' published today, the international expert panel warns that many scientists are unwittingly using poor-quality chemical probes, leading to mistaken conclusions being drawn from research studies.

Fatherhood makes men fat
Men gain weight after they become fathers for the first time, reports a large new Northwestern study that tracked the weight of more than 10,000 men from adolescence to young adulthood. The 'fatherhood effect' is an average weight gain of 3.5 to 4.5 pounds after the first child. Men who do not become fathers lose weight during this period. This is a key time for pediatricians to counsel fathers, who often don't have their own doctors.

Examination of use of diabetes drug pioglitazone and risk of bladder cancer

Blood vessels can actually get better with age
Oxidative stress has been linked to cardiovascular and neurodegenerative diseases including diabetes, hypertension and age-related cancers. However, researchers at the University of Missouri recently found that aging actually offered significant protection against oxidative stress. These findings suggest that aging may trigger an adaptive response to counteract the effects of oxidative stress on blood vessels.

New techniques improve specificity of CRISPR/Cas9 genome editing tools
To overcome the off-target mutations that commonly occur with CRISPR/Cas9 genome editing methods, researchers at Harvard Medical School and Massachusetts General Hospital have developed two strategies that greatly improve the specificity of RNA-guided nucleases for the DNA region targeted to be cut and repaired. A description of these new techniques and their successful use to modify human cancer cells and embryonic stem cells is described in a special issue on genome editing in Human Gene Therapy.

Patients' own genetically altered immune cells show promise in fighting blood cancer
In recent years, immunotherapy has emerged as a promising treatment for certain cancers. Now this strategy, which uses patients' own immune cells, genetically engineered to target tumors, has shown significant success against multiple myeloma, a cancer of the plasma cells that is largely incurable. The results appeared in a study published online today in Nature Medicine.

Study: The Angelina Jolie Effect on breast cancer screening
Angelina Jolie received widespread media attention in 2013 when she told the public that she'd tested positive for BRCA1, a gene associated with an increased risk of breast and ovarian cancers, and subsequently had a double mastectomy. Now research shows that this publicity did influence some women's intentions to seek out similar genetic testing.

MD Anderson study finds one-third of colorectal cancers diagnosed before 35 are hereditary
Hereditary colorectal cancers, caused by inherited gene mutations, are relatively rare for most patients. However, researchers at The University of Texas MD Anderson Cancer Center have discovered a particularly high prevalence of hereditary cancers among those diagnosed with the disease before the age of 35.
