Vascular cell generation could be used to treat vascular disorders

A study in mice has shown that large numbers of vascular endothelial cells can be generated from human amniotic fluid-derived cells.

Highlights of colorectal cancer research from ACG annual scientific meeting

Women under age 50 who have been diagnosed with endometrial cancer, and first, second and third degree relatives of patients with colorectal cancer may have an increased risk of developing colorectal cancer (CRC), according to two separate studies unveiled today at the American College of Gastroenterology's (ACG) 77th Annual Scientific meeting in Las Vegas.

Austrian researchers receive $7.4 million award to verify new breast cancer pathways

The innovator's award recognises Josef Penninger's work in identifying a key molecular pathway how hormone replacement therapies and contraceptive pills can lead to breast cancer. His team provided the first genetic proof that a protein called RANKL is the master regulator of bone loss, which has contributed to the development of a novel drug already approved for the treatment of osteoporosis and skeletal related events in multiple cancers.

Sickle cell disease treatments: An interview with Dr Niihara, CEO of Emmaus Medical

Sickle cell disease is a devastating hereditary condition that affects millions of people, particularly those in West and Central Africa as well as people of African descent in the United States, Europe and South America.

Thin ideal internalization: an interview with Jessica Suisman and Kelly Klump

Thin-ideal internalization is the extent to which a person identifies with the cultural ideal that thinness is equivalent to attractiveness.

Glioblastoma multiforme can originate from cortical neurons

Scientists have long believed that glioblastoma multiforme (GBM), the most aggressive type of primary brain tumor, begins in glial cells that make up supportive tissue in the brain or in neural stem cells. In a paper published October 18 in Science Express, however, researchers at the Salk Institute for Biological Studies have found that the tumors can originate from other types of differentiated cells in the nervous system, including cortical neurons.

Methylation provides clues to gastric cancer subtypes

Research published in Science Translational Medicine shows that many gastric cancers are associated with significant epigenetic alterations along the DNA triggered by methylation.

New approach to prevention of breast cancer wins $7.4M award

A new approach to possible future prevention of breast cancer and slowing the spread of tumours has won Austrian researcher Josef Penninger, director of the Institute of Molecular Biotechnology of the Austrian Academy of Sciences (IMBA) in Vienna, a $7.4 million innovator's award to continue his research, from the USA's Congressionally Directed Medical Research Program.

Epigenetic alteration associated with increased risk of breast cancer

Monozygotic twins have the same genome, that is, the same DNA molecule in both siblings. Despite being genetically identical, both twins may have different diseases at different times. This phenomenon is called "twin discordance". But how can people who have the same genetic sequence present different pathologies and at different ages? The explanation partly lies in the fact that the chemical signals added in the DNA to "switch off" or "switch on" genes can be different. These signals are known as epigenetic marks.

Closer to engineering new kidney tissue

With a worldwide shortage of kidneys for patients who need kidney transplants, researchers are diligently working to find ways to engineer new kidney tissue from a patient's own cells or another source. They've come a step closer to realizing that goal with a breakthrough described in an upcoming Journal of the American Society of Nephrology (JASN) study.

Researchers identify how mosquito's immune system attacks specific infections

Researchers at the Johns Hopkins Bloomberg School of Public Health have determined a new mechanism by which the mosquitoes' immune system can respond with specificity to infections with various pathogens, including the parasite that causes malaria in humans, using one single gene.

Reprogrammed vascular endothelial cells from ACs shows promise against vascular disorders

A new approach for generating large numbers of circulatory system cells, known as vascular endothelial cells (VECs), from human amniotic-fluid-derived cells (ACs) is reported in a study published by Cell Press October 18th in the journal Cell. The strategy, which shows promise in mice, opens the door to establishing a vast inventory of VECs for promoting organ regeneration and treating diverse vascular disorders.

New discovery could help revolutionize antibiotic treatment of bacteria

Three Simon Fraser University scientists are among six researchers who've made a discovery that could help revolutionize antibiotic treatment of deadly bacteria.

Study shows children with low levels of gene activity develop anxious dispositions

Decreased activity of a group of genes may explain why in young children the "fear center" of the anxious brain can't learn to distinguish real threats from the imaginary, according to a new University of Wisconsin study.

Childhood poverty, demographics associated with DNA methylation patterns

A University of British Columbia and Centre for Molecular Medicine and Therapeutics (CMMT) study has revealed that childhood poverty, stress as an adult, and demographics such as age, sex and ethnicity, all leave an imprint on a person's genes. And, that this imprint could play a role in our immune response.

New study decodes complete epigenome of chronic lymphocytic leukemia

Researchers of the University of Oviedo have contributed to decipher the first epigenomes of chronic lymphocytic leukemia.

Reprogrammed endothelial cells for treatment of vascular disorders

A research team at Weill Cornell Medical College has discovered a way to utilize diagnostic prenatal amniocentesis cells, reprogramming them into abundant and stable endothelial cells capable of regenerating damaged blood vessels and repairing injured organs.
