A new drug to help young patients with genetic obesity

In a new study researchers from the Institute for Experimental Pediatric Endocrinology of the Charité – Universitätsmedizin Berlin have successfully treated patients whose obesity is caused by a genetic defect. Aside from its beneficial effects on the patients, the researchers also provided insights into the fundamental signalling pathways regulating satiety of the new drug. A […]

TAILORx trial finds most women with early breast cancer do not benefit from chemotherapy

 New findings from the groundbreaking Trial Assigning Individualized Options for Treatment (Rx), or TAILORx trial, show no benefit from chemotherapy for 70 percent of women with the most common type of breast cancer. The study found that for women with hormone receptor (HR)-positive, HER2-negative, axillary lymph node-negative breast cancer, treatment with chemotherapy and hormone therapy […]

High-sensitivity troponin test reduces risk of future heart attack

A blood test that measures the presence of heart-specific proteins called troponins is used by emergency clinics to diagnose myocardial infarction in patients with chest pain. For the past few years a newer laboratory method has been used at most hospitals in Sweden that is ten times more sensitive than the conventional troponin test. The […]

Blood mutations could contaminate genetic analyses of tumours

Genetic mutations in blood cells that have made their way into tumours could be red herrings that mislead physicians looking for genetic changes in tumours that are helping to drive the cancer. This finding is significant because physicians could make misinformed treatment decisions. University of North Carolina Lineberger Comprehensive Cancer Center researchers and colleagues will […]

Organoid profiling personalizes treatments for pancreatic cancer

Patient-derived organoids, hollow spheres of cells cultured from tumours, can quickly and accurately predict how patients with pancreatic cancer respond to a variety of treatments, facilitating a precision-medicine approach to the deadly disease. The ability to use organoids as a treatment tool was investigated by an international team of researchers led by Dr. David Tuveson, […]

Dicer cuts down on fats

The enzyme Dicer cleaves long precursors into short RNA molecules called microRNAs. A new study reveals how Dicer enhances energy metabolism and reduces levels of fat storage in macrophages, thus slowing the progression of atherosclerosis. Atherosclerosis is one of the primary causes of premature death in modern societies. The condition is characterized by the deposition […]

Leukaemia: protective role of Y chromosone gene discovered

Researchers have found that UTY, a gene on the Y chromosome, protects male mice lacking the tumour-suppressing UTX gene on the X chromosome from developing acute myeloid leukaemia Researchers at the Wellcome Sanger Institute and the University of Cambridge found that this Y-chromosome gene protects against the development of Acute Myeloid Leukaemia (AML) and other […]

Chemical octopus catches sneaky cancer clues, trace glycoproteins

Cancer drops sparse chemical hints of its presence early on, but unfortunately, many of them are in a class of biochemicals that could not be detected thoroughly, until now. Researchers at the Georgia Institute of Technology have engineered a chemical trap that exhaustively catches what are called glycoproteins, including minuscule traces that have previously escaped […]
