Researchers discover new genetic disease related to vitamin B12 deficiency

Vitamin B12 is essential to human health. However, some people have inherited conditions that leave them unable to process vitamin B12. As a result they are prone to serious health problems, including developmental delay, psychosis, stroke and dementia. An international research team recently discovered a new genetic disease related to vitamin B12 deficiency by identifying a gene that is vital to the transport of vitamin into the cells of the body.

SUMO1 protein may treat and/or prevent heart failure

A promising new drug target for the treatment and prevention of heart failure has been discovered by researchers at Mount Sinai School of Medicine in New York, NY, US. The study was presented at the ESC Congress 2012 by principal investigator Professor Roger J. Hajjar, MD.

Creighton University research to improve patient care and outcomes in CAD treatment

Since 1990, Creighton University School of Medicine professor and researcher Devendra K. Agrawal, Ph.D., has been awarded more than $20 million in research grants to study coronary artery heart disease. He is determined to eradicate the impact of this heart disease—the number one killer of men and women in the United States.

Personalized colon cancer therapy based on genetics of specific cancer

University of Minnesota Medical School and Masonic Cancer Center researchers have partnered with geneticists from Genentech, Inc., to discover how some proteins may cause the development of some forms of colon cancers.

ALDH enzyme marks melanoma stem cells

Cancer stem cells are defined by three abilities: differentiation, self-renewal and their ability to seed a tumor. These stem cells resist chemotherapy and many researchers posit their role in relapse. A University of Colorado Cancer Center study recently published in the journal Stem Cells, shows that melanoma cells with these abilities are marked by the enzyme ALDH, and imagines new therapies to target high-ALDH cells, potentially weeding the body of these most dangerous cancer creators.

Abnormalities in mitochondrial length promote development of neurodegenerative diseases

Goldilocks was on to something when she preferred everything "just right." Harvard Medical School researchers have found that when it comes to the length of mitochondria, the power-producing organelles, applying the fairy tale's mantra is crucial to the health of a cell. More specifically, abnormalities in mitochondrial length promote the development of neurodegenerative diseases such as Alzheimer's.

Study demonstrates how DBP production is modulated by daily variations of temperature

Numerous processes in our body fluctuate in a regular pattern during the day. These circadian (or daily) variations can be driven by local oscillators present within our cells or by systemic signals controlled by the master pacemaker, located in the brain. Ueli Schibler, professor at the University of Geneva (UNIGE), Switzerland, unveils a molecular mechanism by which body temperature rhythms influence the expression of 'clock genes' and synchronize local oscillators.

Parental methylated histones not transferred to daughter DNA

It's widely accepted that molecular mechanisms mediating epigenetics include DNA methylation and histone modifications, but a team from Thomas Jefferson University has evidence to the contrary regarding the role of histone modifications.

Certain human diseases may have evolutionary epigenetic origins

Ninety-six percent of a chimpanzee's genome is the same as a human's. It's the other 4 percent, and the vast differences, that pique the interest of Georgia Tech's Soojin Yi. For instance, why do humans have a high risk of cancer, even though chimps rarely develop the disease? In research published in September's American Journal of Human Genetics, Yi looked at brain samples of each species. She found that differences in certain DNA modifications, called methylation, may contribute to phenotypic changes.

Changes in DNA methylation might be linked to evolution of humans' vulnerability to diseases

Chimpanzees rarely get cancer, or a variety of other diseases that commonly arise in humans, but their genomic DNA sequence is nearly identical to ours. So, what's their secret? Researchers reporting in the September issue of the American Journal of Human Genetics, a Cell Press journal, have found that differences in certain DNA modifications, called methylation, might play a role.

Researchers deciphered function of claudin-10 gene in the kidney

Sodium chloride, better known as salt, is vital for the organism, and the kidneys play a crucial role in the regulation of sodium balance. However, the underlying mechanisms of sodium balance are not yet completely understood.

The Wistar Institute, MSKCC partner to publish first annotated atlas of Epstein-Barr virus genome

Researchers from The Wistar Institute and Memorial Sloan-Kettering Cancer Center (MSKCC) have teamed to publish the first annotated atlas of the Epstein-Barr virus genome, creating the most comprehensive study of how the viral genome interacts with its human host during a latent infection. Epstein-Barr virus (EBV), which is thought to be responsible for one percent of all human cancers, establishes a latent infection in nearly 100 percent of infected adult humans.

Scripps Research Institute scientist to uncover workings of the immune system

A team led by a scientist at The Scripps Research Institute has received a $22.5 million, five-year project renewal from the National Institutes of Health to uncover the workings of the immune system.

New method can differentiate between breast cancer patients with good and poor prognosis

It is now possible to identify aggressive breast cancers by interpreting the mathematical patterns in the cancer genome. Researchers at the University of Oslo, Norway (UiO) have developed a completely new method for differentiating between breast cancer patients with high and low risks of dying from the illness.

PHF20 transcriptional factor plays a unique role in regulating p53

Researchers at Moffitt Cancer Center and colleagues have identified PHF20, a novel transcriptional factor, and clarified its role in maintaining the stability and transcription of p53, a gene that allows for both normal cell growth and tumor suppression. PHF20, the researchers found, plays a previously unknown and unique role in regulating p53.

Influenza virus can change microRNA expression to control immune responses in human lung cells

When you are hit with the flu, you know it immediately -- fever, chills, sore throat, aching muscles, fatigue. This is your body mounting an immune response to the invading virus. But less is known about what is happening on the molecular level.

MOZ protein could explain variations in severity of DiGeorge syndrome

The discovery of a 'switch' that modifies a gene known to be essential for normal heart development could explain variations in the severity of birth defects in children with DiGeorge syndrome.

NCKU research team identifies Au nanorod complex for cancer therapy

A National Cheng Kung University (NCKU) research team has discovered Near-Infrared Light-Responsive oligonucleotide-gated Au nanoensembles (Au nanorod complex), a potent new anti-cancer complex that is seen as a promising targeted therapy for curing cancer.

New UCLA study pinpoints unique human patterns of gene activity in the brain

Human and chimp brains look anatomically similar because both evolved from the same ancestor millions of years ago. But where does the chimp brain end and the human brain begin? A new UCLA study pinpoints uniquely human patterns of gene activity in the brain that could shed light on how we evolved differently than our closest relative.

Microtubule stiffening worsens skeletal muscle degeneration in Duchenne muscular dystrophy

University of Maryland (UM) researchers and collaborators report in the journal Science Signaling that skeletal muscle degeneration in Duchenne muscular dystrophy (DMD) is worsened by stiffening of the microtubule cytoskeleton that provides structure inside muscle cells.
