Test predicts response to treatment for complication of leukemia stem cell treatment

Patients with fatal blood cancers like leukemia often require allogenic stem cell SCT to survive. Donor stem cells are transplanted to a recipient, but not without the risk of developing GVHD, a life-threatening complication and major cause of death after SCT. The disease, which can be mild to severe, occurs when the transplanted donor cells (known as the graft) attack the patient (referred to as the host). …

Mechanics of cells’ long-range communication modeled by researchers

By developing mathematical models of how the collagen matrix that connects cells in tissue stiffens, the researchers are providing insights into the pathology of fibrosis, cirrhosis of the liver and certain cancers. Tissue stiffness has long been know to be clinically relevant in these diseases, but the underlying changes that alter the mechanics of tissues are poorly understood…

Whole-genome sequencing can successfully identify cancer-related mutations — ScienceDaily

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…

Light-emitting e-readers before bedtime can adversely impact sleep

“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…

Polymorphism, bacteria inside us help dictate inflammation, antitumor activity

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…
