Thinking Outside the Box to Make Significant Advances in Disease Research


As a scientist and basic biology researcher, it can be difficult to explain how laboratory work at the cellular and molecular level will positively impact human health. In short, basic biology is the critical first step required to make important advances in the medical field. Although bench scientists may not interact with patients on a daily basis like physicians, we are driven to improve lives through inquiry and discovery. Through our own personal experiences with disease and our innate detective skills, we are motivated to investigate the intricacies of the cell and work toward findings that will lead to new treatments. Even though basic science is vital for clinical development of new medicines, research as a whole still needs to find a way to rise above incremental improvements and (at the risk of sounding too cliché) "think outside the box." This type of thinking is even supported by federal grant opportunities that eliminate or deemphasize the need for traditional preliminary data. As physicist David Bohm put it, "[t]he ability to perceive or think differently is more important than the knowledge gained."
Our lab's research at Van Andel Institute is largely conducted with a focus on cancer, but given our expertise when it comes to the mTOR pathway, we are also positioned to study other diseases -- for example, tuberous sclerosis complex (TSC). Because TSC is not a cancer, traditional academia might consider the disease outside our "box." Characterized by tumors in vital organs, including the brain, eyes, skin, heart, kidneys and lungs, TSC can cause serious health problems, such as autism and epilepsy. The disease has varying degrees of manifestations, from mild to severe, and is generally diagnosed during childhood. Seizures and infantile spasms can be extremely detrimental to the development of young patients. TSC tumors are not malignant, meaning that they are not cancer and do not metastasize, and the majority of disease occurrences result from mutations in the either Tsc1 or Tsc2 genes. These two genes play an important role in suppressing tumor growth and are part of the mTOR pathway. Although my team can be characterized as a cancer research lab, we can also leverage our cancer pathway perspective to better study this tumor-causing disease. What we learn in the process will not only benefit the TSC field but will have implications for cancer research.
While branching out into a new disease area could be considered an "outside-the-box" approach, investigating study outliers is another unorthodox tactic for making discoveries. Scientists have realized that there are a vast number of unknowns when it comes to diseases like cancer and TSC, which can be highly individualized and specific to a person's unique genome. As a result, the traditional drug development process may no longer be the most effective approach to combating genetic diseases. The National Cancer Institute and other oncologists are taking a unique approach to advancing cancer treatment. Scientists are taking a closer look at patients whose disease responded favorably to investigational drugs that failed in traditional clinical trials. These studies validate the notion that each individual's disease is different and represent a resourceful strategy to investigate cancer and ultimately make meaningful discoveries for patients. This road less traveled could lead to significant advances in the cancer field.
Personalized medicine is another innovative research method making more than just incremental progress in health research. With the development of genome sequencing and its relatively new affordability of sequencing, personalized medicine can match patient genomes with individualized treatment plans. Personalized medicine can involve a cocktail of approved and investigational drugs, some of which may not normally be prescribed for the patient's disease. Prescribing a drug generally used to treat cardiovascular disorders to treat an unrelated disease certainly represents a radical approach. Personalized medicine has proven to be successful for some cancer patients. With the help of experienced clinical collaborators, our lab is breaking ground to bring this strategy to TSC patients. It is our hope that this personalized medicine collaboration will result in rapid advances for TSC patients, whose current treatment options consist of surgery to remove tumors from affected organs, and therapies that address TSC symptoms.
Scientists and researchers want to make a positive impact on human health and improve lives. Whether it's biologists at the laboratory bench or clinicians at the patient's bedside, we are all hoping and striving to make discoveries that benefit the health of patients. Although research progress has traditionally taken an incremental route, innovative and unorthodox approaches are the tickets to major advances. My hope is that biomedical researchers utilizing these approaches will continue to innovate and discover new and effective treatments in years, rather than in decades.

My 50 Favorite Quotes About Space

For nearly 20 years I have collected a list of my favorite quotes about space. After careful consideration, these are my favorite 50. I hope you enjoy them.

2. Nothing endures but change. - Heraclitus, about 500 B.C.

3. If I could get one message to you it would be this: the future of this country and the welfare of the free world depends upon our success in space.

6. Flight by machines heavier than air is unpractical and insignificant, if not utterly impossible. - Simon Newcomb, 1902
(eighteen months before Kitty Hawk.)

Report: One in Five Reptiles at Risk of Extinction


A lizard basking in the hot sun

A new study by the Zoological Society of London has found that 19% — nearly one in five — of the world’s 10,000 species of reptiles are threatened with extinction. The study, which has been printed in the journal Biological Conservation, was carried out by more than 200 experts who assessed the risk of extinction of 1,500 reptiles selected at random from around the globe.
The primary author of the paper, Monika Bohm, explained to the Zoological Society: “reptiles are often associated with extreme habitats and tough environmental conditions, so it is easy to assume that they will be fine in our changing world.” However, that’s far from the truth: “Many species are very high specialized in terms of habitat use and the climatic conditions they require for day to day functioning,” Bohm said. “This makes them particularly sensitive to environmental changes.” The paper highlights three critically endangered species in its research, including the jungle runner lizard Ameiva vittata, which has only ever been spotted in the Cochabamba region of the Bolivian jungle — an area under threat from the growth of agriculture and logging. The two most recent searches for the species have been unsuccessful, writes the study. Meanwhile in Haiti, six of the nine species of Anolis lizard in the country risk extinction due to increased deforestation.
Also at risk are freshwater turtles, with 50% of all species at risk of extinction from hunting; turtle parts are in high demand as ingredients in traditional medicine. According to the study 30% of freshwater reptile species are also in danger of completely disappearing.
Reptiles have a long evolutionary history: certain orders, such as snakes, lizards, amphisbaenians (worm lizards), crocodiles and tuataras first appeared on earth around 300 million years ago. They are an important part of many ecosystems, and play roles as both predator and prey. “This is a very important step towards assessing the conservation status of reptiles globally,” Philip Bowles from the IUCN Species Survival Commission said in response to the study. “Tackling the identified threats, which include habitat loss and harvesting, are key conservation priorities in order to reverse declines in these reptiles.”
