Genomics, Proteomics…Beeromics?

For decades, a lucky subset of molecular biologists have been engaged in the study of beer diligently trying to figure out the science behind the drink’s clarity, taste and foam content. While most of us are content with studying beer after work hours, researchers from France and Japan worked many hours to uncover 18 proteins within the beer proteome that likely influence its delectable characteristics. Although their results are certainly noteworthy, the protocols utilized suffered from sample input limitations (less than 10 ml of sample per run) and consequently a relatively small number of proteins were discovered. Then came the Italians…

In a paper published in the Journal of Proteome Research , scientists from Milan utilized a protein enrichment strategy to identify 54 types of proteins from Italian-bottled Splügen beer. The group used Proteominer technology from Bio-Rad Laboratories to magnify low-abundant proteins that would have otherwise been lost with a protein depletion approach. They then analyzed the remaining fractions by mass spectrometry analysis and identified over 40 proteins that were present in trace amounts in the beer sample.

Lead author Pier Giorgio Righetti, of the The Polytechnic Institute of Milan told Discovery News “This opens up a completely new horizon in beer analysis in general, and also in the analysis of any beverage. We are now analyzing a lot of other beverages and finding a lot of surprising things that producers don’t know are in their beverages.”

Fast qPCR assay optimization and validation techniques for HTS

Following hot on the heals of yesterdays post “A Practical Approach to Assay Design for qPCR“, we are proud to present you with another practical SlideShare on Fast qPCR assay optimization and validation techniques for HTS (high throughput screening). As with the previous presentation, the slide deck can be maximized for easier reading.

Genetic breakthrough for brain cancer in children

An international research team led by the Research Institute of the McGill University Health Centre (RI MUHC) has made a major genetic breakthrough that could change the way pediatric cancers are treated in the future. The researchers identified two genetic mutations responsible for up to 40 per cent of glioblastomas in children – a fatal cancer of the brain that is unresponsive to chemo and radiotherapy treatment. The mutations were found to be involved in DNA regulation, which could explain the resistance to traditional treatments, and may have significant implications on the treatment of other cancers. The study was published this week in the journal Nature.

Below is a talk that was moderated this past summer by corresponding author Nada Jabado, Clinician and Principal Investigator at RI MUHC. The talk focuses on cancer initiation and cancer growth.

Test your gene knowledge with the Talking Glossary of Genetic Terms

Animal Cell: Courtesy: National Human Genome Research Institute.

By far, one of the best sites on the web for learning about genomics is the NIH’s Talking Glossary of Genetic Terms. The website has a menu with a comprehensive list of relevant terms. Clicking on the hyperlinks gives you access to animated tutorials narrated by some of the best minds in the business along with non-copywrite images and 3D animations that help give viewers a clear understanding of the topic they are interested in.

For the experienced scientist, the website is a useful resource for helping explain to your friends and family exactly what you do in the lab and for finding illustrations to use in any way you choose (the site is in the public domain and therefore information may be freely distributed and copied).

For some extra fun, there is a “test your gene knowledge” quiz, which contains 10 questions that I expect all Canadian Biotechnologists to answer with ease. Here’s an example of a question below.

I took the test and scored a 10/10 and I am attaching the certificate below to prove it. (I’m not going to tell you how many times I took the test before I received a perfect score;-)

Woohooo! Perfect Score!

And of course, the Talking Glossary is also available on the app store. Be sure to check it out today!

Beardomics: How your beard holds the key to determining your risk of developing cancer

This is by far one of the funniest videos that I have seen in the lab comedy genre on the internet! Beardomics definitely deserves two thumbs up. Kudos to Unicorns of the Hydrocalypse for a fantastic video!

One of my favourite lines from the video is when he explains that hundreds of pounds of beard hair sample is kept at -80C “not for preservation…just because I don’t like the smell!” What’s your favourite part?
