Means to an end … (Part of a strategy to achieve better science for better health and well being )
Problem/Concern: Current research is NOT sufficiently Reproducible to achieve scientific aims.
Hypothesis: Improved reproducibility thru Rigorous Robust Relevant research design and reporting will improve validity, & human & animal health…
Corollary Animal welfare & well being (3R’s) is good for research …
Is Reproducibility the real goal?

NEXT STEPS? TODAY, now:• Understanding mouse names Reporting mice accurately in Materials and Methods of Your NEXT paper…

• Regarding Materials and Methods (M&M)– Background strain:
• …The use of shortened stock and strain designations (e.g., Sprague‐Dawley rat or C57BL mouse) instead of the fully defined genetic nomenclature is not appropriate in published animal descriptions….
– Microbial status:• …list of the pathogens excluded, reference to the pathogen exclusion

BALB/c killer males?• ….Scott did not select or purposely breed BALB/c mice for aggressive behavior ….In 1942 he notes that weanling BALB/c males could be housed 5 to a cage ... Further BALB/c albinos became lethargic in warm weather.
• …These observations put us at a loss to explain why BALB/cJ males are viciously aggressive when compared with their docile BALB/cAn ….

Mice/Names•CONCLUSIONS: Strain matters. Sex matters. Beware of incomplete or inaccurate names… Be aware of nomenclature …
Final Exam : (Your research!)o WHY do you use a specific strain or substrain?o Relevant phenotypes/genotypes to your research?o Would other strains be useful to your research?

Nomenclature – mission critical in scientific communication…
• Correct strain names identify strain(s) of origin, and where it has been, and came from
• Correct mutant names tell a lot about the mice & mutations
• Incorrect names compromise communication, reproducibility, translational research

Where are we now ?(in terms research reproducibility)
What we have : (Survey ‘data’)
Guidelines Recommendations
Concerns, Complaints, POOR Reproducibility, POOR reporting….

Betteranimal and
human health
What we learned from a 2017 Survey onExternal Environmental factors
• 180 responses as of 10/14/17 (AALAS)• Average response time ~ 5min • Compmed, MGI list, institutional list serves, colleagues ….
• Not a perfect survey • But pretty quick • Interesting:

Overwhelming Majority:YES its important BUT…
• we need mechanisms to facilitate collecting and reporting (69%}
• it does not seem necessary to publish or to get grants (41%)
DISCLAIMER(s)/Disclosures• This presentation reflects MY (conscious and unconscious) biases that some thing(s) should be done to improve research reproducibility and validity….
• The content does NOT represent or reflect the views of Johns Hopkins University or Johns Hopkins Health system, or of ILAR or the National Academies.

What is our ??
• Research reproducibility?
• Animal welfare?• Less animal research?• No animal research?• Improved animal and human health?
...via better reproducibility, data validity, and more predictive outcomes ……
