The basic human body plan is fairly similar (most have eyes, arms, and legs) but how efficiently our bodies\u2019 function is unique and depend heavily on our genes. Although our brains use a lot of the simple energy compounds (like glucose), our skeletal muscles use 70% of our body\u2019s total energy production such as fats, sugars, and amino acids. All of this energy demand from our skeletal muscles means our body\u2019s metabolism is highly regulated by our muscles. If you want a higher metabolism then you should work out more to gain muscle; this process of muscle formation or repair is a complicated sequence of events requiring hundreds of genes all working together at the right time to promote muscle development. However, if one or many genes do not function properly this sequence of events have inefficiencies that diminish our muscle production capability; for some this means more time at the gym but for others it could lead to diseases like diabetes.<\/p>\n

Our guest this evening is Vera\u00a0Lattier<\/a> (Chih-Ning Chang)\u00a0who is a PhD candidate in the Molecular and Cellular Biology Program<\/a> focusing on one gene in particular that orchestrates the muscle formation process at various stages of life development. This PITX2 gene is implicated in regulating the activity of other genes<\/a> as well as formation of the eyes, heart, limbs, and abdominal muscles during embryonic stages. During later stages of life the amount of skeletal muscle you have dictates your bodies metabolism, and if you are unable to build muscles you tend to have a lower metabolism that encourages excess food to be stored as fat. This is the first step towards obesity and is also a precursor to developing diabetes that affects nearly 26 million people<\/a> in the United States. Although eating right and exercising can have a substantial impact to your health, if your genes are not functioning correctly poor health may ensue at no fault of the patients.<\/p>\n

Vera\u2019s research<\/a> uses mice as models to better understand this complex interaction between our genes and our body\u2019s metabolism. As part of a decade\u2019s long research<\/a> through Dr. Chrissa Kioussi\u2019s research lab<\/a> at Oregon State University they examined the role of this PITX2 gene<\/a> in three main stages of muscle formation. By mutating the gene to affect it\u2019s expression (effectively \u2018turning off\u2019 the gene) during early embryonic formation the mice bodies were unable to effectively create the physical structures for basic bodily functions and they were not viable embryos. When mutating the gene near the time of birth the mice were fully functional at the early stage of life and seemed normal. However, when they grew older they quickly became obese, in fact three times as heavy as the average mice, that lead to fatty liver disease, enlargement of the heart, obesity, and of course diabetes. Vera\u2019s work continues to try and elucidate the mechanisms behind the connection of our genes and our body\u2019s metabolism through structural muscle formation that could help us to identify these limitations earlier and help save lives.<\/p>\n

There is so much more to discuss with Vera on tonight\u2019s show. You\u2019ll hear about her first experience with a microscope at a young age and how she dreamed of one day becoming an evil scientist (luckily her parents changed her mind). Be sure to tune in for what is sure to be an enlightening discussion on Sunday April 8th<\/sup>\u00a0at 7PM on KBVR Corvallis 88.7FM or by\u00a0listening live<\/a>.<\/p>\n
