Dopamine D2 receptor gene can prolong lifespan

Researchers at the University at Buffalo Research Institute on Addictions have discovered how a gene in the brain's dopamine system can play an important role in prolonging lifespan: it must be coupled with a healthy environment that includes exercise.

Scientists derive first molecular model of critical transporter at blood-brain barrier

Scientists from Duke-NUS Medical School have derived a structural model of a transporter at the blood-brain barrier called Mfsd2a. This is the first molecular model of this critical transporter, and could prove important for the development of therapeutic agents that need to be delivered to the brain --- across the blood-brain barrier. In future, this could help treat neurological disorders such as glioblastoma.

Fructose common in western diet can damage brain genes

A range of diseases -- from diabetes to cardiovascular disease, and from Alzheimer's disease to attention deficit hyperactivity disorder -- are linked to changes to genes in the brain. A new study by UCLA life scientists has found that hundreds of those genes can be damaged by fructose, a sugar that's common in the Western diet, in a way that could lead to those diseases.

First breakthrough in gene therapy against aging

In September 2015, then 44 year-old CEO of BioViva USA Inc. Elizabeth Parrish received two of her own company's experimental gene therapies: one to protect against loss of muscle mass with age, another to battle stem cell depletion responsible for diverse age-related diseases and infirmities.

Modulation of estrobolome may help lower breast cancer risk

Investigating disparities in the composition of the estrobolome, the gut bacterial genes capable of metabolizing estrogens in both healthy individuals and in women diagnosed with estrogen-driven breast cancer may lead to the development of microbiome-based biomarkers that could help mitigate the risk of certain cancers, according to a review paper published April 22 in the JNCI: Journal of the National Cancer Institute.

Researchers develop real-time single molecule electronic DNA sequencing platform

Researchers from Columbia University, with colleagues at Genia Technologies, Harvard University and the National Institute of Standards and Technology report achieving real-time single molecule electronic DNA sequencing at single-base resolution using a protein nanopore array.

Study shows cancer cell death via necroptosis can drive pancreatic tumor growth

The most aggressive form of pancreatic cancer - often described as one of the hardest malignancies to diagnose and treat -- thrives in the presence of neighboring tumor cells undergoing a particular form of "orchestrated cell death." This is according to a major study recently published in the journal Nature.

Sleep loss influences cholesterol metabolism, study finds

Lack of sleep has previously been found to impact the activation of the immune system, inflammation, carbohydrate metabolism and the hormones that regulate appetite. Now University of Helsinki researchers have found that sleep loss also influences cholesterol metabolism.

Researchers describe how bed bugs break down insecticides

There are many reasons why bed bugs have made a comeback in recent decades, and their resistance to commonly used insecticides is one of the most widely accepted explanations.

NASA's research program uses omics to look more closely at individual health

NASA's Human Research Program is releasing the first half of a video series entitled Omics: Exploring Space Through You to highlight its Twins Study, in conjunction with its National DNA Day Reddit Ask Me Anything event at 10 a.m. CDT/11 a.m. EDT, Monday, April 25, 2016. The series explores space through you by using omics to look more closely at individual health.

Under-expressed miR-9 gene may contribute to schizophrenia risk

By turning skin cells into brain neurons, researchers at the Icahn School of Medicine at Mount Sinai have identified that certain tiny molecules aiding in gene expression, known as microRNAs (miRNAs), are under-expressed in the brains of the 14 schizophrenia patients they studied. Their findings, published online today in the journal Cell Reports, show that one of these molecules, a miRNA known as miR-9, is a risk factor that controls the activity of hundreds of genes.

Targeted therapy for triple-negative breast cancer may prove beneficial

A targeted therapy for triple-negative breast cancer (TNBC), the most aggressive form of breast cancer, has shown potential promise in a recently published study. TNBC is the only type of breast cancer for which there are no currently approved targeted therapies.

Long way to go in better understanding brain abnormalities linked with autism

A recent review that examined all published studies on anatomical abnormalities in the brains of individuals with Autism Spectrum Disorder found substantial discrepancy throughout the literature regarding the reported presence and significance of neuroanatomical findings.

Novel function of PLK1 gene in prostate cancer metastasis

Researchers at VCU Massey Cancer Center have uncovered a novel function of the gene PLK1 (polo-like kinase 1) that helps prostate cancer cells metastasize (spread) to other parts of the body. This mechanism highlights new potential targets for cancer therapies and challenges the previous understanding of PLK1's role in cancer growth and progression.

Unique mouse model could help study genetic origins and potential treatments for ALS

University of Florida Health researchers have developed a unique mouse model that will allow researchers around the world to better study the genetic origins and potential treatments for a neurodegenerative brain disease that causes amyotrophic lateral sclerosis, often referred to as ALS or Lou Gehrig's disease, and frontotemporal dementia.

Rab inhibition may be a promising antimyeloma strategy

Roswell Park Cancer Institute researchers are investigating agents that target and disrupt the trafficking of monoclonal antibodies in multiple myeloma, a cancer of the bone marrow. The results will be presented at the American Association for Cancer Research Annual Meeting 2016, to be held April 16-20 in New Orleans.

Wellderly study finds link between cognitive decline genes and healthy aging

An eight-year-long accrual and analysis of the whole genome sequences of healthy elderly people, or "Wellderly," has revealed a higher-than-normal presence of genetic variants offering protection from cognitive decline, researchers from the Scripps Translational Science Institute (STSI) reported today in the journal Cell.

Assessing body composition may help predict cardiovascular and total mortality

Researchers from the David Geffen School of Medicine at UCLA found that cardiovascular disease patients who have high muscle mass and low fat mass have a lower mortality risk than those with other body compositions. The findings also suggest that regardless of a person's level of fat mass, a higher level of muscle mass helps reduce the risk of death.

Disorders in PIGG gene can cause intellectual disability with seizures and hypotonia

A research group led by Osaka University and collaborative institutions discovered that disorders in the same gene PIGG are the cause for intellectual disability with seizures and hypotonia. PIGG is one of the enzymes active in the GPI anchor glycolipid synthesis and the current study revealed its significance in the development of the cerebral nervous system.

Study indicates that resolvin D1 has anti-arthritic properties

Rheumatoid arthritis (RA) is a debilitating autoimmune disorder that is characterized by the accumulation of inflammatory cells within the fluid of the joints. Current therapeutic strategies mostly serve to ease pain and rarely are able to reverse damage or resolve inflammation.
