Two recent papers may have upturned two common beliefs about adult stem cells: One reported that there appears to be stem cells in the esophagus, while the other reported that a fetal stem cell that can become either a liver cell or an endothelial cell.
Starting Monday, millions of people who have avoided colon cancer screening can get a new home test that's noninvasive and doesn't require the icky preparation most other methods do. The test is the first to look for cancer-related DNA in stool.
A new comprehensive analysis of thyroid cancer from The Cancer Genome Atlas Research Network has identified markers of aggressive tumors, which could allow for better targeting of appropriate treatments to individual patients.
Physicians will tell you: They are not winning the war on ovarian cancer. But researchers have combined medicine and advanced nanotechnological engineering to create a smarter, more targeted therapy that could overcome the most lethal gynecologic cancer.
Researchers now developed a new way to model the effects of these genetic mutations in mice. The approach, based on the genome-editing technique known as CRISPR, is much faster than existing strategies, which require genetically engineering mice that carry the cancerous mutations.
Researchers have pinpointed a set of intriguing characteristics in a previously unknown subpopulation of melanoma cancer cells in blood vessels of tumors.
Scientists have uncovered details about how cancer is able to become drug resistant over time, a phenomenon that occurs because cancer cells within the same tumor aren’t identical.
Researchers have found a way to kill prostate cancer cells by delivering a trove of copper along with a drug that selectively destroys the diseased cells brimming with the mineral, leaving non-cancer cells healthy.
Pancreatic cancer likely takes between 10 and 20 years to develop, providing the potential for a very “broad window” of intervention if detected early, which may be possible for people who inherit a predisposition, say researchers.
The discovery of a cellular snooze button has allowed a team of scientists to potentially improve biofuel production and offer insight on the early stages of cancer.
In rare cases, patients with allergies to metals develop persistent skin rashes after metal devices are implanted near the skin. New research suggests these patients may be at increased risk of an unusual and aggressive form of skin cancer.
Researchers have identified a set of RNA molecules that are detectable in tissue samples and urine of prostate cancer patients, but not in normal healthy individuals.
Green tea has long been known for its anti-oxidant, anti-cancer, anti-aging and anti-microbial properties. Now, a group of researchers has taken the health benefits of green tea to the next level by using one of its ingredients to develop a drug delivery system.
Scientists have taken pictures of the BRCA2 protein for the first time, showing how it works to repair damaged DNA. Mutations in the gene that encodes BRCA2 are well known for raising the risk of breast cancer and other cancers.
Much of biomedical research these days is about big data—collecting and analyzing vast, detailed repositories of information about health and disease. These data sets can be treasure troves for investigators, often uncovering genetic mutations that drive a particular kind of cancer, for example.
Scientists discovered a mechanism that promotes the progression of medulloblastoma, the most common brain tumor found in children. The team found that a protein known as Sonic Hedgehog induces DNA damage, which causes the cancer to develop.
Researchers have identified microRNAs that may cause colon polyps from turning cancerous. The finding could help physicians provide more specialized, and earlier, treatment before colon cancer develops.
Researchers from the National Cancer Institute want to know how many past and present cancer cases in New Mexico may be related to the U.S. government's test of the world's first atomic bomb over a remote stretch of desert nearly 70 years ago.
Years before they show any other signs of disease, pancreatic cancer patients have very high levels of certain amino acids in their bloodstream, according to a new study.
New research has answered the long-standing question of why mutations to the RB1 gene primarily cause tumors of the retina and not of other cell types. The study could reveal new cellular signaling pathways relevant to retinal development, cancer development, and ultimately, the development of novel therapies.
On this episode of Bioscience Technology This Week, Christina Jakubowski reports on a discovery that claims the smell of mown grass is actually an SOS for help in resisting insect attacks. Our second story covers the possibility that modified vitamin D can help fight pancreatic cancer.
High levels of calcium in blood, a condition known as hypercalcemia, can be used by GPs as an early indication of certain types of cancer, according to a new study.
Bacillus anthracis bacteria have very efficient machinery for injecting toxic proteins into cells, leading to the potentially deadly infection known as anthrax. A team of researchers has now hijacked that delivery system for a different purpose: administering cancer drugs.
An analysis of circulating tumor cells (CTCs) in a mouse model of pancreatic cancer has identified distinct patterns of gene expression in several groups of these cells, including significant differences from the primary tumor that may contribute to their ability to spread.
Scientists have developed an approach to creating treatments for osteoporosis and autoimmune diseases that may avoid the risk of infection and cancer posed by some current medications.
