Molecular Approaches to Neuroscience

"...I had a much better understanding of the language of the techniques so that I could better interact with the people in the lab who were doing the work."
--Allan I. Basbaum, UCSF

Many scientists liken working in a molecular lab to cooking. The conventional wisdom is that the gourmet, perhaps even the gourmand, makes for a better bench scientist. The reasoning? Well, much molecular lab work resembles cooking---from preparing the reagents, cultivating cultures, measuring mixes and reactions, knowing how and how long to heat the "dish." The metaphors rise like well-leavened bread. Although not always pleasing to the sense of smell, the molecular lab is definitely recognizable by its redolent odors of bugs, buffers and chemicals.

Attempting to correctly deliver a few microliters of a precious sample into a nearly translucent well only a bit wider than a pipet tip is a challenge at first try. After the umpteenth gel, though, sample loading becomes second nature. The tools of molecular biology involve exact sample manipulations, which can bring any scientist to his or her knees, literally. It's just one right of passage into the esoteric world of molecular biology.

If you're not a natural cook, the molecular lab can be a daunting place---populated by so many unique utensils and fresh ingredients ready to spoil and not far removed from the watchful eyes of cantankerous diners (a.k.a. granting agencies) who will only pay for the best cuisine. The BioPharmaceutical Technology Center Institute (BTCI) and Promega Neurosciences offer a training course in recombinant DNA technologies for classically trained neuroscientists wanting to learn molecular biology. 

Early this summer, science students from across the United States congregated in Madison for five days of intensive training and instruction in Molecular Approaches to Neuroscience. From the classically trained neuroscientist to the non-neuroscientist, these students gathered to hone their laboratory skills in molecular biology and to learn new ones.

Most came to learn, some to improve, but all wanted to enhance their practical understanding and hands-on use of molecular techniques. Mary Behan, a neuroanatomist at the University of Wisconsin, p853.gif (19759 bytes)enrolled to "learn the language of molecular biology...the readings, lecture presentations and finally seeing what it was all about. It took the mystery out of molecular biology." This sentiment was echoed by many of the class participants.

Mary is currently studying how age and gender affect the brain serotonergic system, especially the areas involved in sleep and breathing disorders, and is interested in furthering her training because she "doesn't want to be technically limited." Learning these molecular techniques first-hand now allows her to better interact with colleagues, whether on a daily basis at her institution or at national meetings such as the Society for Neuroscience Annual meeting. An additional bonus of the course has been the initiation of collaborative studies with fellow neurobiologists. There's no doubt that new techniques enhances networking opportunities.

"Participating in the course took the mystery out of molecular biology...I lost a lot of my intimidation."
--Mary Behan, University of Wisconsin

Who Came to Dinner?

The advanced scientific course was held at the BTC (on the campus of Promega Corporation) in Madison, Wisconsin. Although each student presented a unique background and training in science, all came together to learn. Students from industry and academia came to enhance their knowledge and understanding of, not to mention practical experience using, molecular techniques.

One popular menu item: reverse transcriptase-PCR, or "RT-PCR." Students isolated RNA from mouse and rat brain tissue using the SV Total RNA Isolation System(a), and amplified specific messages for NGF and beta-Actin, not an atypical technique in many neuroscience laboratories today. See the eNotes applications article, "Measuring Gene Expression in Mammalian Brain Tissue" for more information.

The instructors lectured on the salient points of the topic of the day, and then the class proceeded to the benches in the teaching laboratories to actually perform and troubleshoot the procedures for themselves.

From Hot-Plate to Industrial Range Cooking

Can a five-day course turn a neuroscientist into a "card-carrying" molecular neuroscientist? Well, no. Or, "NO!," as some students made perfectly clear (see Q&A).

But the seeds of understanding certainly can be nurtured. Students picked up many of the skills needed to design and perform experiments using molecular techniques---handling RNA, accurately constructing a reaction mix and loading samples in delicate gels perched in awkward electrophoresis equipment: Tools that allow the neuroscientists to open up many new possibilities for dissecting their specific scientific questions.

See the section, Q&A, to see what the students thought of the tightly integrated lecture/laboratory exercises.
