Scientists decode stability blueprint of rhomboid enzyme

Johns Hopkins scientists have decoded for the first time the "stability blueprint" of an enzyme that resides in a cell's membrane, mapping which parts of the enzyme are important for its shape and function.

Gene discovery made for infant-onset blindness

Researchers have discovered that mutations in the NMNAT1 gene encoding nicotinamide mononucleotide adenylyltransferase 1 are present in patients with Leber congenital amaurosis.

Biomimetic bioartificial livers and cell toxicity assays: an interview with Dr. Joris Braspenning, CEO Medicyte

Biomimetic bioartificial livers are liver organoids based on synthetic equivalents of the human extracellular matrix (ECM) which will be seeded with human cells.

Gluconeogenesis severely compromised in HCC by IL6-Stat3-mediated activation of miR-23a

As liver cancer develops, tumor cells lose the ability to produce and release glucose into the bloodstream, a key function of healthy liver cells for maintaining needed blood-sugar levels.

Antioxidants and pancreatic cancer risk: an interview with Dr Andrew Hart

The antioxidants that we mainly looked at were selenium, vitamin C and vitamin E. They are chemicals which inactivate pro-oxidants or free radicals. Smoking and normal metabolism can lead to the production of free radicals.

Researchers isolate elusive human gene that causes NMNAT1-related Leber congenital amaurosis

Researchers from the Massachusetts Eye and Ear Infirmary, The Children's Hospital of Philadelphia, Loyola University Chicago Health Sciences Division and their collaborators have isolated an elusive human gene that causes a common form of Leber congenital amaurosis (LCA), a relatively rare but devastating form of early-onset blindness. The new LCA gene is called NMNAT1.

Long-term linagliptin effective treatment for Type 2 diabetes

Linagliptin is an effective and well-tolerated therapy for the long-term management of Type 2 diabetes, say the authors of an open-label extension study published in the International Journal of Clinical Practice.

Potential biomarker to predict lung cancer patients' response to chemotherapy

Patients with the most common type of lung cancer are notoriously insensitive to chemotherapy drugs, including cisplatin. New findings related to the cellular pathways that regulate responses to cisplatin have now been published by Cell Press on July 26th in the journal Cell Reports.

Fusion of FGFR and TACC gene leads to glioblastoma

Researchers at Columbia University Medical Center (CUMC) have discovered that some cases of glioblastoma, the most common and aggressive form of primary brain cancer, are caused by the fusion of two adjacent genes.

Vitamin A insufficiency linked to hand, foot and mouth disease

Vitamin A status is associated with immunity to, and pathogenic condition of, hand, foot, and mouth disease in children, say researchers whose study results show that the majority of those with the infectious disease also had vitamin A insufficiency.

Raising dopamine levels in frontal cortex reduces impulsivity in healthy adults

Raising levels of the neurotransmitter dopamine in the frontal cortex of the brain significantly decreased impulsivity in healthy adults, in a study conducted by researchers at the Ernest Gallo Clinic and Research Center at the University of California, San Francisco.

Molecular explanation for increased susceptibility to intestinal inflammation in malnutrition

More than one billion people in poor countries are starving, and malnutrition remains a major problem even in rich countries, making it a leading cause of death in the world. For over a hundred years, doctors have known that a lack of protein in the diet or low levels of amino acids, the building blocks of proteins, can lead to symptoms like diarrhoea, inflamed intestines and other immune system disorders, which weaken the body and can be fatal. However, the molecular mechanism which explains how malnutrition causes such severe symptoms has been largely unexplored.

Single event of brain trauma can lead to Alzheimer’s

A study, performed in mice and utilizing post-mortem samples of brains from patients with Alzheimer’s disease, found that a single event of a moderate-to-severe traumatic brain injury (TBI) can disrupt proteins that regulate an enzyme associated with Alzheimer’s. The paper, published in The Journal of Neuroscience, identifies the complex mechanisms that result in a rapid and robust post-injury elevation of the enzyme, BACE1, in the brain. These results may lead to the development of a drug treatment that targets this mechanism to slow the progression of Alzheimer’s disease.

New tool uses fluorescence to distinguish cancerous tissue from normal one in low-grade tumors

A new probe developed collaboratively at Norris Cotton Cancer Center and Dartmouth College's Thayer School of Engineering uses an innovative fluorescence-reading technology to help brain surgeons distinguish cancerous tissue from normal tissue. The probe tool, now already in use at the Cancer Center for brain surgery, may one day be used for surgeries for a variety of cancers.

Moderate-to-severe TBI can disrupt proteins that regulate enzyme associated with Alzheimer's

A study, performed in mice and utilizing post-mortem samples of brains from patients with Alzheimer's disease, found that a single event of a moderate-to-severe traumatic brain injury (TBI) can disrupt proteins that regulate an enzyme associated with Alzheimer's.

New FDA guidelines on HIV And TB drug doses may not apply to African and Asian patients

In January, 2012, the U.S. Food and Drug Administration (FDA) issued new guidelines on dosing of an HIV medication used to treat people infected with both HIV and tuberculosis (TB) because of a potential interaction between two of the main drugs used to treat each disease.

Scientists identify mechanisms by which GLP-1 protects against kidney disease, diabetes

Scientists at Joslin Diabetes Center have identified biological mechanisms by which glucagon-like peptide-1 (GLP-1), a gut hormone, protects against kidney disease, and also mechanisms that inhibit its actions in diabetes.

Scientists demonstrate link between cancer and faulty differentiation of stem cells

Stem cells hold great promise for the medicine of the future, but they can also be a cause of disease. When these self-renewing, unspecialized cells fail to differentiate into diverse cell types, they can start dividing uncontrollably, leading to cancer. Already several decades ago, Weizmann Institute scientists were among the first to demonstrate the link between cancer and the faulty differentiation of stem cells. Now a new Weizmann Institute-led study, published in Molecular Cell, reveals a potential molecular mechanism behind this link.
