Summertime Collaboration in Cuernavaca


About an hour south of the University of Arizona campus by car and with a quick walk across the border you can find yourself in a foreign country.  Therefore, when we think of travel abroad, Mexico doesn't always seem to fit the description we originally have in mind.  Many college students look to Mexico as a place to party while on spring break, rather than a culturally rich country filled with amazingly warm and friendly people, and that's a shame.  Over this past summer I had the privilege to travel to the Institute of Biotechnology, a branch of the Autonomous National University of Mexico and work in the laboratory of Dr. Jorge Nieto through BRAVO!  Located a little over one-thousand miles southeast of Tucson the Institute is located in the quaint city of Cuernavaca nestled in the side of a volcanic mountain range in the state of Morelos, Mexico.  During my time in Cuernavaca I learned how amazing our neighbor to the south truly is.   

When I found out that I was going to become an international scientific collaborator, I didn't know exactly what that would entail.  I now understand that such a position walks a fine line between being a scientist and being the subject of an experiment.  As a scientist I embarked on a project concerning the role of a protein chaperone that aids in the cellular response to stress.  In yeast, heat shock protein 104 (Hsp104) helps damaged proteins regain their function.  Additionally, Hsp104 has a role in regulating certain protein structures known as amyloids. Amyloids are associated with certain human conditions like Alzheimer's disease and Type 2 Diabetes, as well as a host of other infectious protein diseases.  Research has been conducted showing the potential for Hsp104 to regulate the formations of amyloids, and thus presenting a novel way to combat serious human maladies.  The physical structure of Hsp104 gives it the unique ability to refold its protein substrates, and my work involved mutating one of the domains in this protein, a middle coiled-coil region connecting two active sites, to see how the overall protective function of Hsp104 was affected.
    
The other half of the BRAVO! experience consists of an interesting psychological experiment in which the subject is dropped into an environment that is both culturally and linguistically different from home.  Whether I was traveling to any of the amazing archaeological sites all over the country, making a trip to the downtown zócalo to browse through hundreds of handmade wares, or merely stepping out of the lab to go to lunch with other students from the institute I did my best to embrace my new surroundings and learn as much as I could in the process.  It doesn't take very long for the excitement of traveling to a foreign country to wear off, and the reality of living abroad for 12 weeks to hit you like a bus speeding across multiple lanes at 80 km/hr.  I don't know that it's possible to fully prepare yourself for the thrill ride of such an experience.  Getting from one place to another while never quite knowing if I was going in the exact right direction seemed like an adventure at first, a very scary adventure.  The humid, rainy climate and the plethora of different flora and fauna, which accompany such an environment, only added to the exciting uniqueness of my summer home.  However, Cuernavaca is home to the biggest bugs I have ever seen in my life.  The winding streets of Cuernavaca formed an intricate and ornate maze filled with hidden wonders to be explored, food to eat, and people to chat with.  However, I found myself quietly hoping that I wouldn't get lost, get sick from the food, or be judged as an arrogant American before I had even spoken two words.

The BRAVO! Program is an experience that will test your character in every possible way, and that's the true beauty behind it.  On the one hand there is no comfort zone, no security blanket.  Essentially everything I experienced in Mexico was something that was new and different, something unforeseen.  Removing the protective layer that being at home provides really shows you how much you can handle.  On the other hand BRAVO! allows you to step into a new reality in which you feel at home.  Working in a lab like that of Dr. Nieto was such an amazing experience.  I truly cannot thank the members of that lab enough for putting up with my abundant supply of questions, my imperfect Spanish, and for showing me such hospitality.  I also cannot express my gratitude to everyone involved in the BRAVO! program, specifically Carol Bender and Christine Duddleston, as well as my principal investigator at the UA, Dr. Elizabeth Vierling, for providing this amazing opportunity and helping me make a long time dream into a reality.  Funding for the BRAVO! program was provided by the National Institutes of Health Grant number: 5 T37 MD001427.
