Researchers use electrokinetic patterning to separate particles and microbes by size

Researchers have demonstrated a new technology that combines a laser and electric fields to create tiny centrifuge-like whirlpools to separate particles and microbes by size, a potential lab-on-a-chip system for medicine and research.

Biological factors, cell behaviour drive tumour growth contributing to therapy failure and relapse

Cancer scientists led by Dr. John Dick at the Princess Margaret Cancer Centre have found a way to follow single tumour cells and observe their growth over time. By using special immune-deficient mice to propagate human colorectal cancer, they found that genetic mutations, regarded by many as the chief suspect driving cancer growth, are only one piece of the puzzle. The team discovered that biological factors and cell behaviour - not only genes - drive tumour growth, contributing to therapy failure and relapse.

Children with changes in bully genes have poor survival

In a genome sequencing study of 74 neuroblastoma tumors in children, scientists at the Johns Hopkins Kimmel Cancer Center and the Children's Hospital of Philadelphia (CHOP) found that patients with changes in two genes, ARID1A and ARID1B, survive only a quarter as long as patients without the changes. The discovery could eventually lead to early identification of patients with aggressive neuroblastomas who may need additional treatments.

Blood test and gene sequencing combined to detect cancer

Scientists at the Johns Hopkins Kimmel Cancer Center have combined the ability to detect cancer DNA in the blood with genome sequencing technology in a test that could be used to screen for cancers, monitor cancer patients for recurrence and find residual cancer left after surgery.

Longer looks: People with mental disabilities have a vote; Genome sequencing raises hope - also anxiety

I may get Alzheimer's disease, I was told after getting my DNA analyzed. I could suffer the consequences of an abnormal blood clot in my heart or my brain. Or perhaps I'll suffer from a disease called primary myelofibrosis that's caused by an overactive bone marrow. All of these were possible outcomes, based on my genetic profile. In each case, the test only gives an increased risk for disease, not a definitive diagnosis.

Loss of IGSF1 gene function causes central hypothyroidism

Loss of function in the X-linked immunoglobulin superfamily member 1 (IGSF1) gene causes central hypothyroidism, testicular enlargement, and variable prolactin deficiency, according to data presented at the 82nd Annual Meeting of the American Thyroid Association in Québec City, Québec, Canada.

Longer looks: Too many pills for dad; Genetic secrets; A supermarket's dietitian

Job burnout can strike workers in nearly any field, but a new study finds that doctors are at special risk. Nearly 1 in 2 U.S. physicians report at least one symptom of burnout, with doctors at the front line of care particularly vulnerable, the study found -- a significantly higher rate than among the general working population.

U-M, IGC launch new joint venture for personalized medicine

As a key step toward providing patients with treatments based on their own DNA profiles, the University of Michigan and the International Genomics Consortium (IGC) have launched a new joint venture that will help usher in an age of personalized medicine.

Research on language gene seeks to uncover origins of the singing mouse

Singing mice (Scotinomys teguina) are not your average lab rats. Their fur is tawny brown instead of the common white albino strain; they hail from the tropical cloud forests in the mountains of Costa Rica; and, as their name hints, they use song to communicate.

Patients with multiple colorectal adenomas may carry germline mutations in APC or MUTYH genes

Among patients with multiple colorectal polyps, the prevalence of certain gene mutations varied considerably by polyp count, according to a study in the August 1 issue of JAMA.

Five recent Science and Nature papers shed light on elusive 'GPCRs'

Readers of the top-ranked scientific journals Science and Nature might have noticed a recent wave of articles, most recently in the July 13, 2012 issue of Science, with deep importance for biology and medicine.

Major new research facility opens at Imperial College London

A major new research facility at Imperial College London designed to expand and accelerate the translation of scientific discoveries into new ways of preventing, diagnosing and treating diseases was officially opened by George Osborne MP, Chancellor of the Exchequer, today.

CDKN1C gene mutation contributes to IMAGe syndrome

A gene previously linked to too much growth in patients has now also been linked to growth restriction. Different forms of the gene can lead to very different conditions, according to research published today in the journal Nature Genetics.

UCLA geneticists identify mutation responsible for IMAGe syndrome

UCLA geneticists have identified the mutation responsible for IMAGe syndrome, a rare disorder that stunts infants' growth. The twist? The mutation occurs on the same gene that causes Beckwith-Wiedemann syndrome, which makes cells grow too fast, leading to very large children.

Majority of gene faults not shared across other biopsies from same tumour

Taking a sample from just one part of a tumour may not give a full picture of its 'genetic landscape', according to a landmark study published in the New England Journal of Medicine.

Drugs that target cholesterol pathway may enhance cancer-killing potential of chemotherapy drugs

Johns Hopkins investigators are testing a way to use drugs that target a cholesterol pathway to enhance the cancer-killing potential of standard chemotherapy drugs. Their tests, in mouse models of pancreatic cancer, may yield new and more effective combinations of current and possibly new anti-cancer drugs.

Scientists track genetic pathway of prostate cancer in new approach to drug discovery

Tracking the genetic pathway of a disease offers a powerful, new approach to drug discovery, according to scientists at the University of California, San Diego School of Medicine who used the approach to uncover a potential treatment for prostate cancer, using a drug currently marketed for congestive heart failure. Their findings are published in the current online issue of the Proceedings of the National Academy of Sciences.
