New molecule can prevent preterm birth

Premature births are intimately linked with inflammation of the uterine tissue, a biological response which induces contractions and preterm labor. In their search for a mean to prevent this phenomenon and complications related to deliveries occurring before 37 weeks of gestation, researchers at CHU Sainte-Justine and University of Montreal discovered an agent that shows efficacy in inhibiting…

Targeting HIV in semen to shut down AIDS

There may be two new ways to fight AIDS -- using a heat shock protein or a small molecule – to attack fibrils in semen associated with the human immunodeficiency virus (HIV) during the initial phases of infection, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

Cells in limbo hold clues for tackling cancer and ageing

For some, TOR may bring to mind a Celtic mountain or perhaps an Internet privacy group. In the world of molecular biology it’s a cellular pathway that’s found in everything from yeast to mammals. mTOR (as it’s called in mammals) plays a central role in instructing the cell to grow and divide in response to nutrients. When it’s turned down, the cell shifts into a second, tidying mode,…

Alternative routes to immortality

Every time a cell divides, the ends of chromosomes – the threads of DNA residing in the nucleus – shorten a bit. Once the chromosome ends, called telomeres, become too short, cells normally stop dividing. Scientists from the German Cancer Research Center (DKFZ) have now discovered how cancer cells make use of specific DNA repair enzymes to extend the telomeres. In this way, they escape the…

Molecular imaging mines deeper

The view across the Atlantic – it fills Professor Fabian Kiessling, Chair of Experimental Molecular Imaging at the RWTH Aachen (Rhine-Westphalia Institute of Technology Aachen), with optimism. The USA offers more opportunities for molecular imaging. Only recently, new tracers for Alzheimer’s were accepted as reimbursable in some centres, whilst the development of new diagnostics in Europe…

How a Bacterial Cell Recognizes its Own DNA

It may come as a bit of a surprise to learn that bacteria have an immune system – in their case to fight off invasive viruses called phages. And like any immune system – from single-celled to human – the first challenge of the bacterial immune system is to detect the difference between “foreign” and “self.” This is far from simple, as viruses, bacteria and all other living things…

Genetic alterations

This article discusses examples of applications of genetic analyses in coagulation disorders and haematological and oncological diseases. Professor Christine Mannhalter highlights the impact changes have on the occurrence and severity of diseases and their influence on therapy response. Report: Christine Mannhalter

Neurons constantly rewrite their DNA

Johns Hopkins scientists have discovered that neurons are risk takers: They use minor ‘DNA surgeries’ to toggle their activity levels all day, every day. Since these activity levels are important in learning, memory and brain disorders, the researchers think their finding will shed light on a range of important questions.

Precision medicine in oncology

Professor Hedvig Hricak MD PhD, Chair of the Department of Radiology at the Memorial Sloan-Kettering Cancer Centre, New York, and Professor of Radiology at Cornell University, Ithaca, New York, is a notable expert on crosssectional anatomic and molecular imaging, particularly of gynaecologic and prostate cancers. EH interviewed her about the potential and impact of more precise viewing of inter-…

Molecular imaging brings seismic change

Molecular profiling is transforming brain cancer management and radiologists must get to grips with the upcoming paradigm that will affect the way they report findings. Renowned neuroradiologist Professor Anne G. Osborn from the University of Utah, School of Medicine, Salt Lake City, unveiled the latest advances in brain pathology during the Nikola Tesla Honorary Lecture last week at ECR…

Xe-MRI advances body exploration

Clinical routine would be inconceivable without MR Imaging. Without exposure to radiation, doctors can make a patient’s organs and tissue structures clearly visible. However, pathological changes in the early stages, degenerated cells or small areas of inflammation, have so far remained almost invisible on these images. In 2014, for the first time, a team of cell biologists, chemists and…

Researchers Find Protein 'Switch' Central to Heart Cell Division

In a study that began in a pair of infant siblings with a rare heart defect, Johns Hopkins researchers say they have identified a key molecular switch that regulates heart cell division and normally turns the process off around the time of birth. Their research, they report, could advance efforts to turn the process back on and regenerate heart tissue damaged by heart attacks or disease.
