(Press-News.org) PHOENIX, Ariz. — April 9, 2014 — Two cell surface receptors might be responsible for the most common form of lung cancer spreading to other parts of the body, according to a study led by the Translational Genomics Research Institute (TGen).
The hepatocyte growth factor receptor (HGFR/MET) and fibroblast growth factor-inducible 14 (FN14) are proteins associated with the potential spread of non-small cell lung cancer (NSCLC), according to the TGen study published online April 8 by the scientific journal Clinical & Experimental Metastasis.
NSCLC represents more than 85 percent of all lung cancers, which this year will kill an estimated 159,000 Americans, making it by far the leading cause of cancer-related death. It has a 5-year survival rate less than 10 percent.
The invasive and metastatic nature of NSCLC contributes to this high mortality rate, and so finding the cause of this potential to spread is key to helping patients survive.
Therapies targeting MET and FN14 are in clinical development, which could lead to treatments that could help halt or slow the spread of this lung cancer.
"As the metastatic phenotype is a major cause of lung cancer mortality, understanding and potentially targeting these pathways may reduce the high mortality rate in advanced lung cancer," said Dr. Timothy Whitsett, an Assistant Professor in TGen's Cancer and Cell Biology Division, and the study's lead author.
Significantly, the TGen study found that MET and FN14 were elevated in metastatic tumors compared to primary lung tumors and suppression of MET activation or FN14 expression reduced tumor cell invasion.
"The elevation of these receptors in metastatic disease opens the possibility for therapeutic intervention," said Dr. Nhan Tran, an Associate Professor in TGen's Cancer and Cell Biology Division, and the study's senior author.
Dr. Glen Weiss, Co-Unit Head of TGen's Lung Cancer Research Laboratory and Director of Clinical Research at Cancer Treatment Centers of America at Western Regional Medical Center, said, "This study identifies some targets that already have drugs in clinical trials, and helps put them into context for what might be a rational drug development approach for the treatment of this deadly cancer."
INFORMATION:
Other institutes that assisted with this study are: the University of Arizona; St. Joseph's Hospital and Medical Center; and Humboldt Medical Specialists.
The study, FN14 expression correlates with MET in NSCLC and promotes MET-driven cell invasion, was funded by the National Institutes of Health, and grants from the St. Joseph's Foundation and the American Lung Association.

Are chromium supplements helpful in lowering blood sugar levels?
2014-04-09
Coral Gables, FL (April 9, 2014) -- Approximately 26 percent of the U.S. population has impaired fasting glucose, which is a predisposition for developing type 2 diabetes, and chromium supplementation has been suggested as a method that may help control and prevent the disease.
A new study by a University of Miami (UM) researcher analyses nearly three decades of data on the effect of chromium supplementation on blood sugar and concludes that chromium supplements are not effective at lowering fasting blood sugar in healthy individuals, or diabetics.
Chromium is a mineral ...
Emerging research suggests a new paradigm for 'unconventional superconductors'
2014-04-09
An international team of scientists has reported the first experimental observation of the quantum critical point (QCP) in the extensively studied "unconventional superconductor" TiSe2, finding that it does not reside as predicted within the superconducting dome of the phase diagram, but rather at a full GPa higher in pressure.
The surprising result, reported in Nature Physics, suggests that the emergence of superconductivity in TiSe2 isn't associated with the melting of a charge density wave (CDW), as prevailing theory holds; in fact the CDW's amplitude decreases under ...
The motion of the medium matters for self-assembling particles, Penn research shows
2014-04-09
By attaching short sequences of single-stranded DNA to nanoscale building blocks, researchers can design structures that can effectively build themselves. The building blocks that are meant to connect have complementary DNA sequences on their surfaces, ensuring only the correct pieces bind together as they jostle into one another while suspended in a test tube.
Now, a University of Pennsylvania team has made a discovery with implications for all such self-assembled structures.
Earlier work assumed that the liquid medium in which these DNA-coated pieces float ...
New climate pragmatism framework prioritizes energy access to drive innovation/development

Drastically improved efforts to provide modern energy access to the poor opens up a new approach to development efforts and action on climate change, an international group of energy and environment scholars say in a new report, Our High-Energy Planet. The report is the first of three in the Climate Pragmatism project, a partnership of Arizona State University's Consortium for Science, Policy, and Outcomes (CSPO) and The Breakthrough Institute.
"Climate change can't be solved on the backs of the world's poorest people," said Daniel Sarewitz, a report coauthor and co-director ...
Vigilance for kidney problems key for rheumatoid arthritis patients
2014-04-09
Rochester, Minn. — Rheumatoid arthritis patients are likelier than the average person to develop chronic kidney disease, and more severe inflammation in the first year of rheumatoid arthritis, corticosteroid use, high blood pressure and obesity are among the risk factors, new Mayo Clinic research shows. Physicians should test rheumatoid arthritis patients periodically for signs of kidney problems, and patients should work to keep blood pressure under control, avoid a high-salt diet, and eliminate or scale back medications damaging to the kidneys, says senior author Eric ...

Stanford scientists model a win-win situation: Growing crops on photovoltaic farms
2014-04-09
Growing agave and other carefully chosen plants amid photovoltaic panels could allow solar farms not only to collect sunlight for electricity but also to produce crops for biofuels, according to new computer models by Stanford scientists.
This co-location approach could prove especially useful in sunny, arid regions such as the southwestern United States where water is scarce, said Sujith Ravi, who is conducting postdoctoral research with professors David Lobell and Chris Field, both on faculty in environmental Earth system science and senior fellows at the Stanford Woods ...
Medication therapy management works for some but not all home health patients
2014-04-09
WEST LAFAYETTE, Ind. — Low-risk Medicare patients entering home health care who received medication therapy management by phone were three times less likely to be hospitalized within the next two months, while those at greater risk saw no benefit, according to a study led by Purdue University.
The study helped determine which patients benefit most from medication therapy management by phone and a way to identify them through a standardized risk score, said Alan Zillich, associate professor of pharmacy practice at Purdue, who led the research.
"Hopefully, this study ...
UC-led research finds chips with olestra cause body toxins to dip
2014-04-09
According to a clinical trial led by University of Cincinnati researchers, a snack food ingredient called olestra has been found to speed up the removal of toxins in the body.
Results are reported in the April edition of the Journal of Nutritional Biochemistry.
The trial demonstrated that olestra—a zero-calorie fat substitute found in low-calorie snack foods such as Pringles—could reduce the levels of serum polychlorinated biphenyls (PCBs) in people who had been exposed to PCBs.
High levels of PCBs in the body are associated with an increase in hypertension and diabetes. ...
Gusev Crater once held a lake after all, says ASU Mars scientist
2014-04-09
TEMPE, Ariz. - If desert mirages occur on Mars, "Lake Gusev" belongs among them. This come-and-go body of ancient water has come and gone more than once, at least in the eyes of Mars scientists.
Now, however, it's finally shifting into sharper focus, thanks to a new analysis of old data by a team led by Steve Ruff, associate research professor at Arizona State University's Mars Space Flight Facility in the School of Earth and Space Exploration. The team's report was just published in the April 2014 issue of the journal Geology.
The story begins in early 2004, when NASA ...
