A 48-year-old patient sees her dermatologist because of a scar-like lesion on her forehead. Even the well-trained physician has trouble to diagnose the lesion: The scar on the woman’s forehead is a rare type of skin cancer — a desmoplastic melanoma…
"Nitric oxide has contradictory roles in cancer progression, and we need new tools in order to better understand it," says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT. …
"We know very little about male breast cancer since it comprises only 0.6 percent of all breast cancer, and nearly all therapy is based on female breast cancer studies. This study demonstrates that just as in women, men with early stage breast cancer have the same outcome with a mastectomy or a lumpectomy followed by radiation. In women, breast-conserving surgery is the standard and preferred treatment for the majority of women…
These new proteins have not previously been associated with T-cell responses. T-cells help fight infections but also can trigger autoimmune diseases or graft vs…
Sequencing spells out, or decodes, the billions of letters of DNA and other genomic data so that clinicians can discover what genetic changes might lead to cancer. Better optics and faster computers, which are the hallmarks of today’s Next Generation Sequencing (NGS), are leading to genomic analysis that enables development of new drugs that target specific genetic mutations. However, because patients’ tumors often contain multiple abnormalities, their cancer often progresses beyond initial targeted therapies…
Working with local hospitals across North Carolina, UNC researchers led by Ronald Chen, MD, MPH, assistant professor of Radiation Oncology in the UNC School of Medicine, and Paul Godley, MD, PhD, Professor in the Division of Hematology/Oncology — both members of the UNC Lineberger Comprehensive Cancer Center — surveyed patients about their decision-making process after a prostate cancer diagnosis. "Prostate cancer is a unique disease where there are multiple treatment options, ranging from active surveillance to surgical treatments to radiation treatments…
The study, published online in the journal Vaccine, examined the association between geographic region and HPV vaccine uptake and completion rates among women ages18-26 in 12 states. It is the first study of its kind to include initiation and completion rates and assess data across multiple years. …
The study, published October 29 in the open access journal PLOS Biology, analyzes how the timing of gene expression is regulated in the notochord, the evolutionary and developmental precursor of the backbone. The notochord is the main feature that sets humans, mice, sea squirts and related animals (collectively known as chordates) apart from flies, worms and mollusks, and is essential for their development. A crucial player in the development of the notochord is the Brachyury gene, which encodes a DNA-binding protein that switches on the expression of numerous notochord genes and ensures their sequential deployment during the formation of this pivotal structure…
The novel therapeutic, which is based on nanotechnology, is small and nimble enough to cross the blood-brain barrier and get to where it is needed — the brain tumor. Designed to target a specific cancer-causing gene in cells, the drug simply flips the switch of the troublesome oncogene to "off," silencing the gene…
The novel therapeutic, which is based on nanotechnology, is small and nimble enough to cross the blood-brain barrier and get to where it is needed — the brain tumor. Designed to target a specific cancer-causing gene in cells, the drug simply flips the switch of the troublesome oncogene to "off," silencing the gene. This knocks out the proteins that keep cancer cells immortal. In a study of mice, the nontoxic drug was delivered by intravenous injection. …
