This is the first study that has used whole-genome sequencing to evaluate a series of 258 cancer patients’ genomes to improve the ability to diagnose cancer-predisposing mutations. The study is published online in the journal EBioMedicine. “Whole-genome sequencing is a new genetic tool that can determine more of a person’s DNA sequence than ever before. Our results show that nearly 90 percent of clinically identified mutations were confidently detected and additional cancer gene mutations were discovered, which together with the decreasing costs associated with whole-genome sequencing means that this method will improve patient care, as well as lead to discovery of new cancer genes,” said Dr…
Endometrial cancer, which arises in the lining of the uterus, accounts for nearly 50 percent of gynecologic cancers diagnosed in the United States, and it is the fourth most common malignancy in women and the eighth most common cause of cancer death. …
Neurosurgeon Dr. Ammar H. Hawasli and colleagues of Washington University School of Medicine, St. Louis, give their perspective on recent guidelines suggesting limited use of CT scans and other neuroimaging tests for patients with headache…
“We found the body’s natural circadian rhythms were interrupted by the short-wavelength enriched light, otherwise known as blue light, from these electronic devices,” said Anne-Marie Chang, PhD, corresponding author, and associate neuroscientist in BWH’s Division of Sleep and Circadian Disorders. “Participants reading an LE-eBook took longer to fall asleep and had reduced evening sleepiness, reduced melatonin secretion, later timing of their circadian clock and reduced next-morning alertness than when reading a printed book.” Previous research has shown that blue light suppresses melatonin, impacts the circadian clock and increase alertness, but little was known about the effects of this popular technology on sleep. The use of light emitting devices immediately before bedtime is a concern because of the extremely powerful effect that light has on the body’s natural sleep/wake pattern, and may thereby play a role in perpetuating sleep deficiency…
“We think everybody has Chitinase 3-like-1 (CHI3L1) in them because it plays a major role in our ability to fight off infections,” said Dr. Jack A…
Researchers have been struggling with what fuels cancer cell growth. For more than 75 years, researchers have known that cancer cells use glucose as the major fuel, but efforts to halt cancer growth by controlling glucose levels in the brain haven’t worked…
The new technique is more than three times as effective as previous methods. Researchers say it’s a major step forward in the study of circulating tumor cells, which are shed from tumors and circulate through the blood of cancer patients. They’re believed to cause metastasis, the spread of cancer through the body that’s responsible for nearly 90 percent of cancer-related deaths. The cells also hold valuable genetic information that could lead doctors to more informed treatment decisions and even tailor-made therapies for individual patients…
The research reveals a more explicit role about the symbiotic relationship humans have with the various bacteria that inhabit our body and their role during tumor progression. “Our research indicates that interactions between the helpful bacteria in our bodies and immune cells at places situated away from tumors influence systemic responses in the host that alter how these tumors are able to progress,” said Jos� Conejo-Garcia, M.D., Ph.D., Associate Professor and Program Leader in the Tumor Microenvironment and Metastasis Program at The Wistar Institute and lead author of the study…
For years, researchers have known that a diverse group of white blood cells called myeloid-derived suppressor cells (MDSC) are more abundant in cancer patients than in healthy individuals. The cells enhance cancer growth and suppress the specialized T cells that target and destroy tumor cells…
