MMRRC Providing COVID-19 Related Mouse Models for Research

COVID-19 is a serious public health threat and researchers around the globe are turning to mouse models as a critical tool in viral pathogenesis, vaccine, and drug treatment discovery research. To help support these efforts, the MMRRC is distributing several COVID-19 related mouse models.

MARC1 - the barcoding lines are now available in the MMRRC!

The MMRRC is now maintaining two exciting new lines with broad applicability and interest to scientists working in many different areas. These mouse lines are called “Mouse for Actively Recording Cells 1” or MARC1. Donated by Dr. George M. Church, Ph.D., and Dr. Reza Kalhor, Ph.D., of Harvard Medical School, they are used for barcoding and lineage tracing applications in the mouse (PMID:30093604). Although these lines do not express any disease-related phenotypes, when a MARC1 mouse is crossed to mice expressing cas9 (universally or in a lineage-specific manner), combinatorial and cumulative barcoding starts in the progeny during their development, leading to developmentally barcoded animals that can be used for a multitude of applications, including lineage tracing.

The available lines are:

STOCK MARC1-PB7/Mmucd, RRID: MMRRC_065424-UCD, was founded by a chimeric male mouse that carried 60 homing guide RNA (hgRNA) loci scattered throughout its genome in a heterozygous state. The founder (#7) was crossed to wild-type C57BL/6J and CD1 mice initially, and the donor then used random intra-strain mating for approximately 10 generations. The genetic background of this line is deemed STOCK due to contributions from more than two inbred lines, and is a mixed background of C57BL/6J, 129S4, and CD1.

STOCK MARC1-PB3/Mmucd, RRID: MMRRC_065812-UCD, was founded by chimera #3 that carried 50 heterozygote germline-transmissible integrations of hgRNAs, including one on chromosome X. The selected founder was crossed with CD1 females to create the F1 generation. The donor used random intra-strain mating for approximately 12 generations prior to depositing to the MMRRC. The genetic background of this line is deemed STOCK due to contributions from more than two inbred lines and is a mixed background of CD1, C57BL/6J, and 129S4.

Please contact our customer service center at service@mmrrc.org if you have any questions about these new lines.

Hybridoma Cell Lines into the MMRRC at UC Davis

The MMRRC is pleased to welcome its newest collection of cell lines to the repository. The UC Davis/NIH NeuroMab Facility has deposited 473 Hybridoma Cell Lines into the MMRRC at UC Davis.

Hybridoma cell lines are immortal monoclonal antibody producing cells that can be grown in tissue culture at any scale to produce monoclonal antibodies. Each of the 473 cell lines in the MMRRC produced monoclonal antibodies validated for the specificity and efficacy in brain research applications at UC Davis/NIH NeuroMab Facility.

This new collection will empower researchers with the ability to produce large quantities of specific and highly validated monoclonal antibodies at low cost. One of the other benefits of having this collection in the MMRRC is that scientists also have access to knockout mouse lines for genes that encode protein targets of the NeuroMAb monoclonal antibodies. Accessibility of these cell lines will allow investigators to explore the dynamic organization of specific cell antibodies critical to understanding and improving health and disease.

MMRRC Announces Availability of KOMP Repository Mice & ES Cells

The Mutant Mouse Resource and Research Center (MMRRC), the official National Institute of Health (NIH) repository of mouse models, is pleased to announce the availability of genetically-altered mice and embryonic stem (ES) cells made as part of the NIH Knockout Mouse Project (KOMP) and previously maintained in the KOMP Repository. The KOMP Repository collection will provide investigators with the convenience of a one-stop portal to one of the largest inventories of mutant mouse strains and ES cell lines available to the biomedical research community.

These newly acquired mouse and ES cell lines have been deposited into the MMRRC at UC Davis. The MMRRC at UC Davis is the largest of four regional archive and distribution centers in the NIH consortium. The MMRRC functions as a single repository resource and is comprised of an Informatics, Coordination and Service Center (ICSC) and three additional regional distribution facilities which include: The Jackson Laboratory, University of Missouri, and University of North Carolina, Chapel Hill. The newly available KOMP Repository mice (4,175 unique lines) & ES cell lines (14,013 unique mutant lines and 7 parental lines) can be accessed by visiting the MMRRC website (www.mmrrc.org) and typing in "KOMP Repository" in the search function, or by using the advanced search function and indicating “Major Collection = KOMP", and then searching by gene of interest, which will allow filtering for ES cells or mice.

The MMRRC was created in 1999, and is supported through the NIH, Office of Infrastructure and Research Programs (ORIP), as the nation’s premier mouse archive and distribution repository. Since that time, the MMRRC has earned an international reputation for the management, cryopreservation, and distribution of scientifically valuable, genetically engineered mouse strains and mouse ES cells. In partnership with researchers around the globe, the MMRRC continues to expand its holdings of mouse models. Today, with more than 59,000 available models, the MMRRC serves as a valuable resource to drive research discoveries for human disease.

MMRRC Education & Outreach Booth Conference Wrap Up

The MMRRC education booth is back from two exciting end of the year conferences in San Diego: ASHG and SfN. Both conferences boasted strong attendance rates, with ASHG claiming their highest attendee count to date. There were many great poster sessions showcasing the latest research efforts involving the use of mouse models. We had the pleasure of meeting many new investigators and students and learning about their research efforts involving the use of mice. We were also excited to provide information about role that the MMRRC plays with archiving and distribution of mouse models, and the importance of rigor and reproducibility. It’s always great to see that our outreach and education efforts can have an impact on increasing awareness of the MMRRC.

KOMP 2 Phase 2 Mouse Lines Available Through The MMRRC

Since 2006, researchers around the world have been working together to generate a targeted knockout mutation for every gene in the mouse genome. The US component of this effort, The Knockout Mouse Project (KOMP), has been providing critical tools for understanding gene function and the genetic causes of human diseases.

In 2016, the National Institutes of Health funded the next phase in the KOMP project called KOMP2 Phase 2 with the objective to produce and phenotype more than 3000 new knockout mouse lines on a C57BL6/N genetic background. Here at the MMRRC, we are pleased to announce that these KOMP2 Phase2 mouse lines will all be made available from the MMRRC repositories. New mouse lines will be added monthly and full phenotyping data will be available.

MMRRC Repository Expands Available Mouse Mutations

Genetically engineered mice serve as valuable models of human disease, contributing to major medical breakthroughs. Often, biomedical researchers must develop unique genetically modified strains of mice for experimentation, a costly and time-consuming process. Now, more researchers in fields from immunology to cancer may be able to save time and money by acquiring genetic material from a repository of previously engineered strains.

Reversal of Behavioral Deficits and Synaptic Dysfunction in Mice Overexpressing Neuregulin 1

When expressed in mice, high levels of Neuregulin 1 (Nrg1) lead to behavioral deficits and hypofunction of glutamatergic and GABAergic pathways similar to that found in human patients with schizophrenia. Don-Yin Min, et al. found that these effects are diminished when Nrg1 levels are returned to normal.
