MBF Labs Contributes to Recent PLOS Article on New Mouse Model for Huntington’s Disease

 

Stereologic volume estimation of the striatum (caudate putamen and nucleus accumbens) confirms changes observed using MRI volumetry in zQ175 knock-in mice.

Stereologic volume estimation of the striatum (caudate putamen and nucleus accumbens) confirms changes observed using MRI volumetry in zQ175 knock-in mice. Stereological analyses showed significant decreases in neuron numbers in homozygous zQ175 knock-in mice aged 4.5 and 10 months (13% and 15% respectively) as compared to age-matched wild-type mice

There is very little known about Huntington’s disease (HD), a fatal neurodegenerative disease leading to total physical and mental decline that affects 30,000 Americans today.

Researchers have been developing transgenic mouse models to mimic human HD. A new model, the zQ175 knock-in, developed by Menalled et al. (2012) appears to more closely mimic human HD progression in the zQ175 KI than previous mouse models.

A recently published paper (co-authored by MBF’s President, Jack Glaser, and Staff Scientist Dr. Susan Hendricks) confirms the behavioral phenotypes reported by Menalled, and extends the characterization to include brain volumetry, striatal metabolite concentration, and early neurophysiological changes. For this study, MBF Labs used Stereo Investigator to quantify neural loss and regional volumetric changes. These changes validate the similarities between HD progression in humans and HD-like progression in zQ175 KI mice.

With this new mouse model, researchers might be able to considerably improve their understanding of the disease to find ways to temper HD progression.

Unveiling WormLab 2.0, the Latest Version of our Groundbreaking Worm Tracking Software

We are delighted to introduce WormLab 2.0.  Our latest version of WormLab features an intuitive step-by-step workflow to analyze the locomotion and behavior of C. elegans and is now available to Mac and Windows 8 users. We’ve worked hard to improve our tracking algorithms, particularly our self-overlap and entanglement algorithms.  We’ve added whole plate mode for tracking many worms on a plate and added extensive camera support for over 1,400 different camera models.  Tracking is much faster throughout and the 64-bit version is even faster than the 32-bit version.

“Researchers are often overwhelmed by the painstaking frame by frame data collection process, often performed over hundreds of frames, which can be a tedious process.  With WormLab, video capture and tracking only take minutes so that researchers can focus on the meaningful part – analysis and interpretation.  Furthermore, the collected data is easily exported for more custom analysis to other software like Excel or Matlab,” says Jeff Sprenger, VP of Research.

Learn more about WormLab from our website and try WormLab 2.0 for free  for 30 days with full technical support.

 

MBF Bioscience Featured on Vermont Public Television

MBF Bioscience was featured in an episode of Emerging Science,  a television series that features Vermont scientists who expand human knowledge and help solve problems around the world.   The episode explored the link between traumatic brain injury and post traumatic stress disorder in military personnel coming back from war.

MBF Bioscience President Jack Glaser and Staff Scientist Susan Hendricks give us some perspective from a research standpoint as they briefly address the ways in which learning more about the injured brain could help find a cure. How does a brain injury affect the neurons in the affected area? Are there fewer neurons than there were before?  Has the shape of the neurons changed? Are there fewer connections between neurons than there were before injury? There is still so much more to explore.
