Five years before brain cancer diagnosis, changes detectable in blood

Interactions among proteins that relay information from one immune cell to another are weakened in the blood of brain cancer patients within five years before the cancer is diagnosed, said lead researcher Judith Schwartzbaum of The Ohio State University. That information could one day lead to earlier diagnosis of brain cancer, said Schwartzbaum, an associate […]

Gene that influences nicotine dependence identified

A DNA variant—located in the DNMT3B gene and commonly found in people of European and African descent—increases the likelihood of developing nicotine dependence, smoking heavily, and developing lung cancer, according to a new study led by RTI International. Nearly 1 billion people smoke and 6 million premature deaths occur worldwide each year from cigarette smoking, […]

Study identifies genes linked to better immune response to flu vaccine

Yale experts and their partners in a national research consortium have identified several genes and gene clusters associated with the immune response to influenza (“flu”) vaccination. The findings point to the prospect of using genetic profiles to predict individual responses to the flu vaccine. The global impact of influenza is substantial, with seasonal epidemics estimated […]

Rare gene variant discovered to contribute to lower pre-eclampsia risk

Researchers at the University of Helsinki, in cooperation with two research groups in the United States, have discovered that some Finnish mothers carry rare gene variants that protect them from pre-eclampsia, also known as toxaemia of pregnancy. This is the first time that mothers’ genotypes have been proven to contain factors that protect against pre-eclampsia. […]

Beckman Coulter highlights the first US IVD test delivering flow cytometric leukemia & lymphoma analysis in the routine clinical lab

ClearLLab reagents are the first to receive Food and Drug Administration (FDA) clearance (via the De Novo Process) to market them in the US.  They deliver the first preformulated, IVD antibody cocktails for leukemia and lymphoma immunophenotyping in the clinical lab. For clinical laboratories it means they no longer have to develop their own laboratory […]

Improved analysis of kidney cancer

Every year, just over 1000 people are diagnosed with kidney cancer in Sweden. The three most common variants are clear cell, papillary and chromophobe renal cancer. Researchers compare the gene expression in tumour cells from a kidney cancer patient with cells from healthy tissue to figure out in which part of the kidney the cancer […]

A new test to detect reliably an autoimmune disease

In autoimmune diseases, the immune system wrongly identifies its "enemy", and produces antibodies that attack the patient’s own cells. One of these diseases, the anti-phospholipid antibody syndrome (APS), is still poorly understood, even though it can have serious consequences. APS is caused by antibodies circulating in the blood plasma that are directed against a protein, […]

Mutations in notch gene to role in B cell cancers

Notch is one of the most frequently mutated genes in chronic lymphocytic leukaemia (CLL), the most common leukaemia in adults in the United States. It is also often mutated in other common B cell tumours, such as mantle cell lymphoma. However, the role of Notch in these cancers has been uncertain. Now, a collaborative effort […]

A blood test can predict early lung cancer prognosis

Cancer cells obtained from a blood test may be able to predict how early-stage lung cancer patients will fare, a team from the University of Michigan has shown. This information could be used to determine which patients are most likely to benefit from additional therapies to head off the spread of the cancer to other […]

Potential cause for lupus identified

Leading rheumatologist and Feinstein Institute for Medical Research Professor Betty Diamond, MD, may have identified a protein as a cause for the adverse reaction of the immune system in patients suffering from lupus. A better understanding of how the immune system becomes overactive will help lead to more effective treatments for lupus and potentially other […]
