Drug used for DNA repair defects could treat leukemia and other cancers more effectively
A team of scientists led by research associate professor Motomi Osato and professor Yoshiaki Ito from the Cancer Science Institute of Singapore at the National University of Singapore found that a drug originally designed for killing a limited type of cancer cells with DNA repair defects could potentially be used to treat leukemia and other cancers.

Deploying exosomes to win a battle of the sexes
A new study provides further detail into how male fruit flies ensure reproductive success by deploying exosomes to alter the mating behavior of females. The findings also identify a signaling pathway that might play a role in human cancers of tissues that secrete exosomes, such as the prostate and breast.

Medicaid reimbursements may affect cancer screening rates among beneficiaries
A recent study has found that in states with higher Medicaid payments for office visits, Medicaid beneficiaries were more likely to be screened for breast, cervical, and colorectal cancer.

RNA sequence could help doctors to tailor unique prostate cancer treatment programs
Sequencing RNA, not just DNA, could help doctors predict how prostate cancer tumors will respond to treatment, according to research published in the open-access journal Genome Biology. Because a tumor's RNA shows the real time changes a treatment is causing, the authors think this could be a useful tool to aid diagnosis and predict which treatment will most benefit individual cancer patients.

Study shows 25 percent fewer opioid-related deaths in states allowing medical marijuana
On average, states allowing the medical use of marijuana have lower rates of deaths resulting from opioid analgesic overdoses than states without such laws. A new multi-institutional study, published in JAMA Internal Medicine and led by researchers at the Perelman School of Medicine at the University of Pennsylvania, shows that on average, the 13 states allowing the use of medical marijuana had a 24.8 percent lower annual opioid overdose mortality rate after the laws were enacted than states without the laws.

Cancer leaves a common fingerprint on DNA
Regardless of their stage or type, cancers appear to share a telltale signature of widespread changes to the so-called epigenome, according to a team of researchers. In a study published online in Genome Medicine on Aug. 26, the investigators say they have found widespread and distinctive changes in a broad variety of cancers to chemical marks known as methyl groups attached to DNA, which help govern whether genes are turned 'on' or 'off.'

Weekend hospitalization linked to longer stay for pediatric leukemia patients
Weekend admission to the hospital for pediatric patients newly diagnosed with leukemia was associated with a longer length of stay, slightly longer wait to start chemotherapy and higher risk for respiratory failure but weekend admissions were not linked to an increased risk for death.

Study suggests repurposing anti-depressant medication to target medulloblastoma
An international research team reports in Nature Medicine a novel molecular pathway that causes an aggressive form of medulloblastoma, and suggests repurposing an anti-depressant medication to target the new pathway may help combat one of the most common brain cancers in children. The scientists say their laboratory findings in mouse models of the disease could lead to a more targeted and effective molecular therapy that would also reduce the harmful side effects of current treatments.

Scientists map risk of premature menopause after cancer treatment
Women treated for the cancer Hodgkin lymphoma will be able to better understand their risks of future infertility after researchers estimated their risk of premature menopause with different treatments. The findings, set out in the Journal of the National Cancer Institute, are based on the experience of more than 2,000 young women in England and Wales treated for the cancer over a period of more than 40 years.

Study shows epigenetic changes in children with Crohn's disease
A new study finds a wide range of epigenetic change -- alterations in DNA across the genome that may be related to key environmental exposures -- in children with Crohn's disease, reports Inflammatory Bowel Diseases, official journal of the Crohn's & Colitis Foundation of America. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

Genetics and lifestyle have a strong impact on biomarkers for inflammation and cancer
In a new study published in Nature Communications, research scientists from Uppsala University present for the first time a large-scale study of the significance of genetic, clinical and lifestyle factors for protein levels in the bloodstream. The results of the study show that genetics and lifestyle are determining factors for protein levels, a discovery which greatly influences the possibilities for using more biomarkers to identify disease.

Deletion predicts survival in advanced non-small cell lung cancer
Bcl-2-like protein 11 deletion in advanced non-small cell lung cancer is associated with shorter progression free survival in epidermal growth factor receptor tyrosine kinase inhibitor or chemotherapy treated Asian patients. Also, Bcl-2-like protein 11 deletion independently predicts overall survival of advanced non-small cell lung cancer patients.

Severe infections with hospitalization after prostate biopsy rising in Sweden
Transrectal ultrasound guided biopsy is the gold standard for detecting prostate cancer, but international reports have suggested that the number of risks associated with the procedure is increasing. In a new nationwide population-based study, Swedish researchers found that six percent of men filled a prescription for antibiotics for a urinary tract infection within 30 days after having a prostate biopsy, with a twofold increase in hospital admissions over five years, reports The Journal of Urology.
