New findings on why skeletal muscle stem cells stop dividing and renewing muscle mass during aging points up a unique therapeutic opportunity for managing muscle-wasting conditions in humans, says a new University of Colorado Boulder study.
According to CU-Boulder Professor Bradley Olwin, the loss of skeletal muscle mass and function as we age can lead to sarcopenia, a debilitating muscle-wasting condition that generally hits the elderly hardest. The new study indicates that altering two particular cell-signaling pathways independently in aged mice enhances muscle stem cell renewal and improves muscle regeneration.
One cell-signaling pathway the team identified, known as p38 MAPK, appears to be a major player in making or breaking the skeletal muscle stem cell, or satellite cell, renewal process in adult mice, said Olwin of the molecular, cellular and developmental biology department. Hyperactivation of the p38 MAPK cell-signaling pathway inhibits the renewal of muscle stem cells in aged mice, perhaps because of cellular stress and inflammatory responses acquired during the aging process.

University of Colorado professor Mike Klymkowsky wants people to understand that evolution isn't inherently easy to understand, and teachers shouldn't pretend it is when talking to students.
He'll describe the difficulties of teaching evolution in a talk Wednesday as part of Darwin Day, a global celebration of science held on the birthday of evolutionary biologist Charles Darwin.
Klymkowsky is a professor in CU's molecular, cellular and developmental biology department and co-director of CU Teach, a math and science teacher preparation program.

When a batch of Avery Brewing Co.'s India Pale Ale goes through the brewing process, the Boulder-based brewer's California Ale Yeast conducts a dynamic performance.
The lively yeast not only helps to develop the alcohol and carbonation for the beer, but its unique genetic makeup also affects the finished product's character by accentuating the floral, citrus and piney hops, and leaving a clean brew.
That delicate dance and its result easily could get muddled if another strain — say, Belgian Wit Yeast — is present in the tank. That yeast, used for Avery's White Rascal Belgian Wheat, could impart its phenolic and spicy attributes on the hoppy flagship beer.

Pink ribbons are for breast cancer, dark blue ribbons are for colon cancer, white ribbons are for lung cancer, gray ribbons are for brain cancer, emerald green ribbons are for liver cancer, and zebra-striped ribbons are for carcinoid cancers. January is cervical cancer awareness month, represented by the teal-and-white ribbon. February is for gallbladder and bile duct cancers, with a kelly green ribbon to represent them. And so on.
As cancer kills more people than ever before, it is natural for us to seek affiliation with those affected by a similar cancer type. Breast cancer patients, survivors and their friends and relatives coalesce their efforts to create awareness and raise funds for breast cancer research and prevention. The same goes for those affected by other cancers, and there is nothing wrong with that. At a time when the National Cancer Institute is losing purchasing power at a scary pace, and when cancer researchers struggle to fund their laboratories, every fundraising and educational effort from organized citizens makes a big difference.
However, we must be very cautious about how brightly we color our ribbons.

Acclaimed University of Colorado Nobel laureate Thomas Cech has added another distinction to his resume with his appointment to the first-ever National Commission on Forensic Science.
Cech, a CU Distinguished Professor who shared the 1989 Nobel Prize in chemistry for the discovery of the catalytic properties of RNA, was one of seven chemists among the 33 commission members who were selected out of a pool of more than 300 applicants.
The commission is a joint project of the U.S. Department of Justice and the National Institute of Standards and Technology.
A statement issued by NIST said members of the commission are charged with working to improve the practice of forensic science by developing guidance concerning the intersections between forensic science and the criminal justice system.
Live Births With Simplified IVF Procedure: Breakthrough Towards Universal and Accessible Infertility Care
December 6, 2013
A recent prospective study published in Reproductive BioMedicine Online comparing conventional IVF with a novel simplified method showed that fertilization and implantation rates were similar for the simplified system when compared with those reported by conventional IVF programs. Sixteen healthy babies have already been born with this new method. According to the results of this study, IVF can be offered at reasonable prices and can be made available to a much larger part of the world population in the near future.

There is a call to label foods as to whether they contain ingredients derived from genetically modified organisms (GMOs.) Not to concern ourselves for the moment with the fact that all modern foods are GMOs, the result of centuries to millennia of human interventions, Craig Schiesley (speaking on the opinion page of the Daily Camera, apparently in his role as a vice-president of a company that stands to gain from such labeling), raises a particularly interesting question, why shouldn't all foods, that is, anything people are expected to eat, be accurately labeled?

Thirty CU undergraduate and graduate students from a wide range of science and engineering departments worked together to design their project: “DIY Synthetic Biology,” taking apart and reconstructing lab techniques and tools and improving them. Over the summer, six students completed the project. Then, these students boarded a plane to Montreal, Canada with their faculty mentor, practiced their presentation until 2:00 a.m., and competed with 52 North American teams, earning an iGEM special award and their place in the upcoming iGEM World Competition in Boston this November.

Protein linked with tumor growth could be potential target for cancer-fighting drugs, according to study led by CU-Boulder
June 7, 2013
A team of researchers led by the University of Colorado Boulder has discovered a protein complex that could be targeted with drugs to stunt tumor growth.
As tumors expand, their centers are deprived of oxygen, and so tumors must flip specific genetic switches to survive in these hypoxic environments.

"I can tell you the exact date that I began to think of myself in the first-person plural — as a superorganism, that is, rather than a plain old individual human being. It happened on March 7. That’s when I opened my e-mail to find a huge, processor-choking file of charts and raw data from a laboratory located at the BioFrontiers Institute at the University of Colorado, Boulder."

In 2013, around 12,000 American women will be diagnosed with invasive cervical cancer and more than 4,000 will die from it. Globally, cervical cancer is the third most common cancer in women worldwide, killing >275,000 every year. But these numbers will go down, must go down, because cervical cancer is now a fully preventable disease. Or isn't it?

Life is an emergent property, something more than the sum of its parts, the irreducible product of complex relationships between inanimate components. After all, we are made of the same stuff as the dead matter around us. But how are we so different? An analysis of our bodies the minute before versus the minute after we die would not show many differences in our atomic, molecular and cellular composition. But the relational status at every level of organization would be drastically different. It's the relationships among our parts that keep us breathing, eating, thinking and loving.

At first glance, the tumor-suppressor gene p53 would seem like an ideal weapon against cancer. It puts the brakes on cancer progression and is impaired in about half of human tumors.
In mouse models of cancer, HHMI investigators Tyler Jacks and Scott Lowe restored p53 activity in tumors and the tumors regressed. However, p53 activation kills some cancer cells, but not others, and no one knows why. HHMI early career scientist Joaquín Espinosa has set his sights on finding an answer, and with it, a strategy for making p53-based therapies effective. It’s a goal he’s pursued with relentless passion.
