Research suggests way to reverse age-related and radiation-induced DNA damage

DNA repair is essential for cell vitality, cell survival and cancer prevention, yet cells' ability to patch up damaged DNA declines with age for reasons not fully understood.

New Danish research provides structural knowledge of DNA repair complex

New Danish research provides mechanistic insight into how DNA is monitored and repaired if damage occurs. The results may eventually help to improve the treatment of certain types of cancer, as the DNA repair complex provides a mechanism for cancer cells to resist chemotherapy.

Researchers identify key mutation that promotes melanoma growth by suppressing immune response

University of California, Irvine researchers have identified a specific mutation that allows melanoma tumor cells to remain undetected by the immune system.

Clinical study seeks to examine new combination therapy for treating AML patients

A pair of drugs that may be a one-two punch needed to help combat acute myeloid leukemia (AML), an aggressive blood cancer that kills nearly three-fourths of patients within five years of diagnosis, is the focus of a new multi-center clinical trial that will enroll patients at three sites across the U.S.

Metabolic vulnerability in triple-negative breast cancer cells may help quell chemotherapy resistance

A team of researchers led by Alex Toker of the Ludwig Center at Harvard has discovered a metabolic weakness in triple-negative breast cancer cells that may be exploited to quell their resistance to chemotherapy.

Researchers looking at ways to target lingering cancer stem cells that cause disease relapse

Chemotherapy treatment targets and kills cancer cells in the body. However, even after treatment, some cancer cells may remain in the patient's system undetected.

Scientists discover how genetic mutation disarms tumor-suppressing BRCA1 proteins in breast cancer

Of the more than 3 million people with breast cancer in the United Stated, about 10 percent carry an inherited mutation in their BRCA1 gene. In health, the gene is responsible for suppressing tumors. In disease, the gene goes terribly awry.

Researchers reveal biological pathways involved in diabetic kidney disease

Diabetes is a leading cause of kidney disease, a serious, often fatal complication that is difficult to diagnose in early, potentially treatable stages.

Recommend daily intake of fruit and veg may need doubling, indicates study

Although eating the recommended five portions of fruit and veg a day is good for you, eating ten portions is even better, according to researchers from Imperial College London.

Eating up to ten portions of fruit and vegetables a day may reduce disease, early death risk

A fruit and vegetable intake above five-a-day shows major benefit in reducing the chance of heart attack, stroke, cancer and early death.

UT Southwestern scientists unravel role of PARP enzymes in major cellular activities

A component of an enzyme family linked to DNA repair, stress responses, and cancer also plays a role in enhancing or inhibiting major cellular activities under physiological conditions, new research shows.

UNC scientists confirm and clarify key molecular details of nucleotide excision repair

Day in and day out, in our bodies, the DNA in cells is damaged for a variety of reasons, and thus intercellular DNA-repair systems are fundamental to the maintenance of life.

New research shows that nuts can inhibit growth of cancer cells

Roasted and salted, ground as a baking ingredient or fresh from the shell - for all those who enjoy eating nuts, there is good news from nutritionists at Friedrich Schiller University Jena.

Defects in key gene spur breast and ovarian cancer growth, study shows

Defects in a key gene - long thought to drive cancer by turning off the protection afforded by the well-known BRCA genes - spur cancer growth on their own, according to a study led by researchers from NYU Langone Medical Center.

Caspase-2 enzyme deficiency linked to higher cancer risk

Researchers from the Centre for Cancer Biology at the University of South Australia have found that a deficiency of caspase-2 enzymes place people at a higher risk of developing tumours.

Study provides insights into molecular mechanisms of ZIKV infection

Zika virus (ZIKV) interferes with the cellular machinery controlling cell division and alters the expression of hundreds of genes guiding the formation and development of neurons and astrocytes, according to findings released on January 23rd 2017 at Scientific Reports.

Tulane researchers discover cancer-causing role of protein thought to be tumor suppressor

Tulane University researchers have discovered that the protein PHLDB3, thought to be a potential tumor suppressor, actually allows cancer cells to thrive in pancreatic, prostate, colon, breast, lung, and other common cancers.
