On June 20th 100 members of the extended MIP family spent a Sunday afternoon in the Park – the ballpark that is – watching the Rockies take on the Milwaukee Brewers. Despite the fact that we all know that Colorado brewers can run circles around Milwaukee’s finest, the visiting team exploded for 5 runs off Manny Corpas in the 8th to beat our Rockies 6-1. Highlights on that hot afternoon included a foul ball off the bat of Jason Giambi that landed a few feet away from Erin and Dave Napier, an unexpected birthday message for John Spencer (see photo above) and a tornado warning in the 8th inning (that may have been the gods warning Rockies fans about the impending Brewers rally).

Rebecca McGill, a Micro major and single mom, who has been working with Project Self-Sufficiency (PS-S), was given a car on July 14th by Houska Automotive as part of a challenge the automotive group is making to encourage local dealerships to help out students in the PS-S program. Thanks Houska!
Liposome-siRNA-Peptide Complexes Cross the Blood-Brain Barrier and Significantly Decrease PrPC on Neuronal Cells and PrPRES in Infected Cell Cultures

Move over Fed-Ex, Bruce Pulford and 16 coworkers just invented ‘Fat-Ex’. If you need to send something quickly and efficiently to the brain, conventional old fashioned delivery methods just don’t work well enough. Fat-Ex is the solution to your shipping problem.
Prion diseases like scrapie, CJD, mad cow and CWD are neurological diseases that are currently untreatable. Over the last ~17 years, it’s been known that if you delete the PrPC gene from animals, you can make them resistant to prion diseases. While we can’t easily (or ethically) delete a gene from a person’s DNA, the 2006 Nobel Prize-winning discovery of RNA interference outlines the use of small RNAs that target mRNAs and dramatically reduce expression from specific genes. There have also been hints in the literature that these small RNAs can be used to knock down PrPC expression and prevent prion diseases. The key question to make this an attractive therapeutic candidate is how to effectively deliver these small RNAs to the brain. Here’s where Fat-Ex steps up to the plate.
Mark Zabel, Steve Dow, Alan Schenkel, et al got together and figured out a way to use cationic liposomes (which consist of lipids (aka fat) to package small RNAs associated with a peptide that will specifically hone the complex to the acetylcholine receptor that is found on neuronal cells. In a nutshell, a simple 29 residue peptide targets the complex to brain cells, a positively charged 9 amino acid tail attracts the small RNA to the peptide, and the lipid vehicle protects it all from degradation on its way to the brain. Sound simple? Well it is – and that’s what makes it elegant. In this paper the group presents very nice data arguing for the stability of the complex in serum over ~4 hrs, effective (~85%) and specific delivery of the small RNA to neuronal cells resulting in impressive (70% or more) knock down of PrPC expression. Similar efficiencies were obtained when the complexes were injected into the tail vein of mice. Importantly, delivery of this small RNA drug was shown to effectively treat cultured neuronal cells that were chronically infected with two different prions.
So why did we pick (yet another) prion study as our coveted MIPublication of the Month® - particularly this month in the face of stiff competition from some excellent papers by the Schweizer, Lenaerts and Wilusz labs? First, this study presents a clever adaptation of existing technologies to create an exciting potential therapeutic avenue for prion diseases which are currently untreatable. Second, at press time this paper has already had almost 600 downloads from the Plos One website – an impressive number particularly for a relatively small field like prion biology. Third, this paper has a ‘Guinness Book of MIP World Record’ 15 MIP researchers – from undergraduates to faculty – listed on the author line. Finally, we bet that this technology will have numerous applications in addition to prion projects. So stop by the Zabel or Dow Labs and ask ‘What can Fat-Ex do for you?’

On July 1st MIP facility offices popped the cork off of some new toner cartridges to celebrate the successful completion of fiscal year FY10 and welcome in FY11. Please take some time out of your busy schedules to stop by your facility office and thank the members of the hard working pit crew that work behind the scenes to keep our department out front in the race to provide the very best teaching, service and research in the university. You guys and gals are the best!

A big THANK YOU goes out to Dr. Carol Blair for adopting Marcia Bogg's kitties!
MIP now has a blog called "The MIP Experience" that allows Faculty and Students to share their experiences as an MIP'er with those interested in learning more about what we do. The blog is a useful source of information for potential students and an interesting way to learn about what your peers are doing!
Currently MIP Undergrads Becca Timmons, Erin Breland, and Alex Griffith are blogging about their awesome summer research experiences. Be sure to check out The MIP Experience and read about what it is like to be a student researcher in MIP. Also, if you have an upcoming MIP Experience that you'd like to blog about just contact Erin Napier and she'll get you setup to start blogging!
