Experts report new outbreaks and increased spread of Cassava Brown Streak Disease

Cassava experts are reporting new outbreaks and the increased spread of Cassava Brown Streak Disease or CBSD, warning that the rapidly proliferating plant virus could cause a 50 percent drop in production of a crop that provides a significant source of food and income for 300 million Africans.

High levels of collagen in breasts are associated with breast cancer metastasis

Researchers at Washington University School of Medicine in St. Louis have discovered why breast cancer patients with dense breasts are more likely than others to develop aggressive tumors that spread.

Study: Combination of chemotherapy and nerve-protecting agents can prevent anemia

Cancer chemotherapy can cause peripheral neuropathy-nerve damage often resulting in pain and muscle weakness in the arms and legs. Now, researchers at Albert Einstein College of Medicine of Yeshiva University have discovered that chemo also induces an insidious type of nerve damage inside bone marrow that can cause delays in recovery after bone marrow transplantation.

Researchers explore biological processes of stem cell division

The human body contains trillions of cells, all derived from a single cell, or zygote, made by the fusion of an egg and a sperm. That single cell contains all the genetic information needed to develop into a human, and passes identical copies of that information to each new cell as it divides into the many diverse types of cells that make up a complex organism like a human being.

Novel screening method for identifying inhibitors of EZH2 methyltransferase

Tumor repressor genes, which inhibit tumor formation, can be "turned off" due to undesirable molecular changes affecting the chromosomes on which the genes reside. Understanding and being able to control these alterations could lead to new approaches for activating or inactivating genes linked to cancer.

Vitamin C may decrease impact of smoking during pregnancy on childhood respiratory health

Pregnant women are advised not to smoke during pregnancy because it can harm the baby's lungs and lead to wheezing and asthma, among other problems. If a woman absolutely can't kick the habit, taking vitamin C during pregnancy may improve her newborn's lung function and prevent wheezing in the first year of life, according to a study to be presented Saturday, May 4, at the Pediatric Academic Societies (PAS) annual meeting in Washington, DC.

Expert to explain how drugs induce damage to DNA in public lecture on May 16

Anticancer drugs save lives and/or improve the quality of life for many cancer patients. Many anti-cancer drugs work by killing tumor cells after inducing damage to DNA.

Researchers identify genetic risk factor for persistent pain after traumatic events

A new study led by University of North Carolina School of Medicine researchers is the first to identify a genetic risk factor for persistent pain after traumatic events such as motor vehicle collision and sexual assault.

Gene mutation associated with rare sleep disorder also contributes to debilitating migraines

A gene mutation associated with a rare sleep disorder surprisingly also contributes to debilitating migraines, a new discovery that could change the treatment of migraines by allowing development of drugs specifically designed to treat the chronic headaches.

Study: Gene mutations are associated with severe form of nearsightedness

People have long taken for granted that glasses and contact lenses improve vision for nearsightedness, but the genetic factors behind the common condition have remained blurry. Now researchers at Duke Medicine are closer to clearing this up.

Study identifies the vector that transmitted malaria from apes to humans

In 2010, a study revealed that the main agent of malaria in humans, called Plasmodium falciparum, arose from the gorilla. Today, the vector which transmitted the parasite from apes to humans has just been identified.

New mechanism that plays important role in meiosis identified

The Research Group headed by molecular biologist Andrea Pichler from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg has made an important discovery in meiosis research.

Study results may help introduce better preoperative treatment for breast cancer

Breast cancers contain many different cell types with different patterns of gene expression, but a new study provides reassurance that this variability should not be a barrier to using gene expression tests to help tailor cancer treatments to individual patients.

Scientists warn of H7N9 risks as number of cases, deaths continue to rise

"A new strain of bird flu that is causing a deadly outbreak among people in China is a threat to world health and should be taken seriously, scientists said on Wednesday," Reuters reports (Kelland, 5/1).

Scientists spell out pivotal role of Peli1 in mouse model of multiple sclerosis

Scientists have identified an influential link in a chain of events that leads to autoimmune inflammation of the central nervous system in a mouse model of multiple sclerosis.

Researchers describe alterations in long noncoding RNA sequences in Rett syndrome

Researchers at the Epigenetics and Cancer Biology Program at IDIBELL led by Manel Esteller, ICREA researcher and professor of genetics at the University of Barcelona, have described alterations in noncoding long chain RNA sequences in Rett syndrome.

NIH-funded study uncovers novel way that grapes exert beneficial effects in the heart

A study appearing in the Journal of Nutritional Biochemistry- demonstrates that grapes are able to reduce heart failure associated with chronic high blood pressure (hypertension) by increasing the activity of several genes responsible for antioxidant defense in the heart tissue.

New approach could democratize viral surveillance, says UCSF scientist

The tick-borne Lone Star virus has been conclusively identified as part of a family of other tick-borne viruses called bunyaviruses, which often cause fever, respiratory problems and bleeding, according to new research led by scientists at UC San Francisco.

Variations in the sequencing of TERT gene influence risk of breast, ovarian cancers

A major international study involving a Simon Fraser University scientist has found that sequence differences in a gene crucial to the maintenance of our chromosomes' integrity predispose us to certain cancers.
