Scientists gain new insights into 'antenna' of human cells

2015-07-13
(Press-News.org) Scientists from the University of Leeds have uncovered the most comprehensive list yet of genes implicated in a group of common inherited diseases.

The research, published in Nature Cell Biology today, means that these disorders, known as ciliopathies, can be diagnosed more quickly and could lead to new treatments for patients.

Ciliopathies are caused by defects in cilia, finger-like projections from cells that act as microscopic "antenna" to detect and respond to chemical changes or fluid flow outside the cell.

Kidney disease, which often leads to kidney failure, is a common complication of ciliopathies and is a significant cause of childhood disease and death.

One in every 1,000 people is born with a ciliopathy, which means there are currently about 30,000 affected people in the UK alone.

The research was led by the University of Leeds in collaboration with colleagues from Nijmegen in the Netherlands and about 40 other institutions worldwide.

Professor Colin A. Johnson, Professor of Medical and Molecular Genetics in the School of Medicine at the University of Leeds, said: "This research gives us the best list yet of the human genes needed to make cilia. This is an important issue in biology, but it also directly benefits patients because we can find new genetic causes for ciliopathies. We've found some completely unexpected cell processes that are linked to these diseases which should help in the search for future treatments."

Professor Ronald Roepman, of the Radboud University Medical Center, Nijmegen, added: "We confirmed that each of the genes on the list were important for cilia using an independent method. We then focused in on some of the biochemical processes that are required for a functioning cilium. But the broader picture still has a wealth of similar opportunities for others in the research community."

The research was funded by the European Union's 7th Framework Programme for Research and Technological Development, known as FP7.

Brain study reveals insights into genetic basis of autism

2015-07-13
UNSW Australia scientists have discovered a link between autism and genetic changes in some segments of DNA that are responsible for switching on genes in the brain. The finding is the result of a world-first study of the human brain that identified more than 100 of these DNA segments, known as enhancers, which are thought to play a vital role in normal development by controlling gene activity in the brain. "Our study provides a unique resource of information on gene function in the human brain which could help reveal the basis of autism and related neurological disorders," ...

VIB-KU Leuven-ULB researchers uncover genetic alterations in development of skin cancer

2015-07-13
Squamous cell carcinoma (SCC) of the skin is one of the most frequent cancers in humans affecting more than half million new persons every year in the world. The transformation of a normal cell to a cancer cell is caused by an accumulation of genetic abnormalities in the progeny of single cells. The spectrum of genetic anomalies found in a variety of human cancers have been described. Squamous cell carcinoma (SCC) arising from various organs including head-and-neck, lung, esophagus and skin, are induced by carcinogens, such as tobacco and UV exposure. Mouse models of carcinogen-induced ...

Report on treatment of patients with hemophilia published

2015-07-13
Numerous long-term randomized controlled trials (RCTs) have been conducted to investigate the long-term, factor concentrate-based treatment of patients with severe haemophilia A or B, despite the rareness of the diseases and the lack of incentives for pharmaceutical companies. These RCTs include three studies comparing prophylactic versus on-demand treatment (i.e. treatment initiated only in the event of bleeding). For patients with haemophilia A, both hints and an indication of an added benefit of prophylactic versus on-demand treatment can be inferred from these studies, ...

Stopping or reducing cocaine use associated with lower cardiovascular risk marker levels

2015-07-13
July 13, 2015 - For people who use cocaine, stopping or reducing cocaine use is associated with decreased levels of endothelin-1 (ET-1)--a protein that plays a key role in the development of coronary artery disease, reports a study in the Journal of Addiction Medicine, the official journal of the American Society of Addiction Medicine. The journal is published by Wolters Kluwer. The findings help in understanding the high rate of atherosclerosis (hardening of the arteries) associated with cocaine use, according to the report by Dr. Shenghan Lai and colleagues of Johns ...

New cell division mechanism discovered

2015-07-13
Canadian and British researchers have discovered that chromosomes play an active role in animal cell division. This occurs at a precise stage - cytokinesis - when the cell splits into two new daughter cells. It was observed by a team of researchers including Gilles Hickson, an assistant professor at the University of Montreal's Department of Pathology and Cell Biology and researcher at the CHU Sainte-Justine Research Centre, his assistant Silvana Jananji, in collaboration with Nelio Rodrigues, a PhD student, and Sergey Lekomtsev, a postdoc, working in the group led by Buzz ...

From sticks to balls: The shape of bacteria is evolving to better adapt to the throat

2015-07-13
This news release is available in French. Montréal, July 13, 2015 - It's no coincidence that the earthworm's slender shape makes it perfect for weaving through narrow tunnels. Evolution moulds the shapes of living creatures according to the benefits they offer. At the microscopic level, do the various shapes of bacteria also contribute to their survival? Does a spherical bacterium (coccus) have a better chance of infecting its host than its stick-shaped neighbour (bacillus)? Analysis of the evolution of the pathogenic bacteria that live in the nasopharynx suggests ...

Registry data used to examine use of ICDs, cardiac rehab referral rates

WASHINGTON (July 13,2015) - The American College of Cardiology's National Cardiovascular Data Registry was the source of data for research published in the first half of 2015, including a study that examines public reporting and PCI outcomes as well as research that showed implantable cardioverter-defibrillators are underutilized in older patients. Is There a Link Between Public Reporting and PCI Outcomes? Patients who underwent percutaneous coronary intervention (PCI) in states with mandated public reporting of outcomes had similar predicted risks but significantly ...

The statement appears in the Journal of Pediatric Gastroenterology and Nutrition, the official journal of the European Society of Paediatric Gatroenterology, Hepatology and Nutrition and the North American Society for Pediatric Gastroenterology, Hepatology and ...

Discovery of young family gives hope to world's rarest ape

2015-07-13
The world's rarest ape has an increased chance of survival after a team led by international conservation charity the Zoological Society of London (ZSL) found a new family group of Hainan gibbons (Nomascus hainanus). Until last month, it was thought that there were just 25 Hainan gibbons living in three social groups on an island off the Chinese mainland. The discovery of a new fourth group, a mating pair with a young baby, sighted within Bawangling National Nature Reserve, Hainan Province, increases the known population by almost 12%. The discovery of this fourth ...
