Identified 2 new genes involved in the more aggressive prostate cancer
2014-05-13
(Press-News.org) A study by the Columbia University Nova York, in collaboration with the Catalan Institute of Oncology , Belvitge Biomedical Research Institute (ICO-IDIBELL) has identified two new genes that lead to more aggressive forms of prostate cancer. The work done by Alvaro Aytes under the direction of Cory Abate-Shen , director of the Herbert Irving Comprehensive Cancer Center of the Columbia University, has been published in the latest issue of Cancer Cell.

Prostate cancer

Prostate cancer is the most common in men in Europe( accounts for 20% of all male tumors). The incidence is about 60 new cases per 100,000 inhabitants per year.

A tumor closely associated with old age, and most cases is diagnosed between 70 and 80 years. The progressive aging of the population has made it one of the tumors that has increased in recent decades. Survival is quite high: according to Oncology Master Plan, 84 % of patients are alive five years after diagnosis.

Identify high-risk patients

In a significant proportion of patients the prostate tumor has a not very aggressive behavior, which does not compromise the health and quality of life of the affected. Also, being a tumor that usually occurs in old age, often the person dies with the tumor but not as a result of this.

It is therefore necessary to develop tools to predict which prostate tumors are clinically relevant and potentially lethal. This would open the door to customize treatments and avoid certain therapies and , therefore, avoid side effects to patients that do not need it, further reducing healthcare costs.

Two new genes in the spotlight

The study published in Cancer Cell identified two genes, the FOXM1 and CENPF, if they are abnormally activated simultaneously, lead to more aggressive and life threatening forms of prostate cancer .

A new feature of the study is that computer algorithms were used to generate networks of interactions between molecules that are generated specifically in prostate cancer .

Currently they have launched preclinical studies to determine which treatments or combinations of drugs are more effective in combating abnormal activation of FOXM1 and CENPF genes. Also, in the near future, identifying the presence or absence of these biomarkers in an individual patient will provide a more effective and with fewer side effects individualized treatment.

INFORMATION: The European Commission through Marie Curie actions of the 7th Framework Programme, has been the source of funding for the development of this Alvaro Aytes project in collaboration between groups of Systems Biology and chemoresistance of ICO- IDIBELL and the University of Columbia , Nova York .

A tale of survival

2014-05-13
Frankfurt am Main, Germany, May 12, 2014. Hydrogen sulphide (H2S) is a potent inhibitor of aerobic respiration. However populations of shortfin molly fish managed to colonise springs with high concentrations of dissolved hydrogen sulphide. In a new study researchers from LOEWE Biodiversity and Climate Research Centre (BiK-F) and the Goethe University Frankfurt present evidence of genetic changes minimizing the harmful effects of H2S which enable the fish to survive in this deleterious environment. The study provides insight into the molecular mechanisms of this key adaptation ...

Bird invaders 'moving in' to UK's nature reserves

2014-05-13
A new study by scientists at the University of York and the RSPB Centre for Conservation Science has demonstrated that nature reserves and other areas specially protected for wildlife, as well as being vital for native species, are very important for helping European birds to expand their ranges into Britain naturally. The catch is that protected areas are also at increasing risk of invasion by species that have been introduced from further afield. The research, published in the journal Diversity and Distributions, explores how the UK's special places for nature have ...

Comet theory false; doesn't explain Ice Age cold snap, Clovis changes, animal extinction

2014-05-13
Controversy over what sparked the Younger Dryas, a brief return to near glacial conditions at the end of the Ice Age, includes a theory that it was caused by a comet hitting the Earth. As proof, proponents point to sediments containing deposits they believe could result only from a cosmic impact. Now a new study disproves that theory, said archaeologist David Meltzer, Southern Methodist University, Dallas. Meltzer is lead author on the study and an expert in the Clovis culture, the peoples who lived in North America at the end of the Ice Age. Meltzer's research team ...

Chemists design molecules for controlling bacterial behavior
2014-05-13
Chemists in the College of Arts and Sciences have figured out how to control multiple bacterial behaviors—potentially good news for the treatment of infectious diseases and other bacteria-associated issues, without causing drug resistance. Yan-Yeung Luk, associate professor of chemistry, has spearheaded the discovery, in conjunction with his research lab at Syracuse University and the Wang Lab at SUNY Upstate Medical University. Their findings are the subject of a forthcoming article in the journal ChemBioChem (John Wiley & Sons Inc.). "Since the discovery of the first ...

UCSF: E-cigarettes expose people to more than harmless vapor, should be regulated

2014-05-13
In a major scientific review of research on e-cigarettes, UC San Francisco scientists found that industry claims about the devices are unsupported by the evidence to date, including claims that e-cigarettes help smokers quit. The review marks the first comprehensive assessment of peer-reviewed published research into the relatively new phenomenon of electronic cigarettes. The devices, which are rapidly gaining a foothold in popular culture particularly among youth, are marketed as a healthier alternative to tobacco smoking, as an effective tool to stop smoking, ...

Scientists from USC and NYU design a molecule that blocks cancer growth in mice

2014-05-13
A team of researchers from USC and NYU has developed and patented a small molecule that interferes with cancer progression with minimal side effects. The molecule prevents two critical proteins from interacting by mimicking the surface topography of one protein – like wearing a mask – which tricks the other protein into binding with it. This stops a so-called "transcription factor" that controls the transcription of genetic information. That transcription factor is what would have created an aberrant gene expression, contributing to the cancer growth. Because of the ...

Scientists slow brain tumor growth in mice

Scientists slow brain tumor growth in mice
2014-05-13
Much like using dimmer switches to brighten or darken rooms, biochemists have identified a protein that can be used to slow down or speed up the growth of brain tumors in mice. Brain and other nervous system cancers are expected to claim 14,320 lives in the United States this year. The results of the preclinical study led by Eric J. Wagner, Ph.D., and Ann-Bin Shyu, Ph.D., of The University of Texas Health Science Center at Houston (UTHealth) and Wei Li, Ph.D., of Baylor College of Medicine appear in the Advance Online Publication of the journal Nature. "Our work ...

Birth by C-section, early antibiotic use put kids at risk for allergic esophagitis

2014-05-13
Children delivered by cesarean section and those given antibiotics during early infancy appear more prone to developing allergic inflammation of the esophagus — the muscular tube that connects the mouth to the stomach — according to results of a study by investigators from the Johns Hopkins Children's Center and Harvard Medical School. The findings, published online May 2 in the Journal of Allergy and Clinical Immunology: In Practice, reveal that early antibiotic treatment and C-section delivery may somehow precipitate disease development by altering a child's microbiota ...

Professional surfer back in the water after successful surgery to treat rare bone cancer

Professional surfer back in the water after successful surgery to treat rare bone cancer
2014-05-13
LOS ANGELES (May 13, 2014) – When professional surfer Richie Lovett began experiencing hip pain at 31, he attributed it to his athletic lifestyle. But after months of discomfort and preliminary tests, the Australian native learned the pain was caused by a cancerous tumor in his femur or thigh bone. "As a professional athlete, I was blindsided by the news that I had cancer," said Lovett. "I realized very quickly that cancer would have a profound effect on my life. I knew I needed an experienced oncologist to tackle this disease, so I began an international search to find ...

Quantum trimer -- from a distance

Quantum trimer -- from a distance
2014-05-13
Eight years ago Rudolf Grimm's research group was the first to observe an Efimov state in an ultracold quantum gas. The Russian physicist Vitali Efimov theoretically predicted this exotic bound state of three particles in the 1970s. He forecast that three particles would form a bound state due to their quantum mechanical properties, under conditions when a two-body bound state would be absent. What is even more astounding: When the distance between the particles is increased by factor 22.7, another Efimov state appears, leading to an infinite series of these states. Until ...
