Hypothesis

The physiological role of Ebp1 in the whole organism is not known.

Conclusion

Ebp1 deficiency leads to reduced growth and altered expression of proliferation-related genes in mice.

Supporting Evidence

  • Ebp1-/- mice were on average 30% smaller than wild type and heterozygous littermates.
  • Growth retardation was observed from Day 10 until Day 30.
  • IGF-1 production was reduced in Ebp1-/- mice.
  • Proliferation of fibroblasts from Ebp1-/- embryos was decreased compared to wild type.

Takeaway

Mice without the Ebp1 gene are smaller than normal mice, but they catch up in size as they grow older.

Methodology

Ebp1-deficient mice were generated using a gene trap insertion, and various assays were performed to assess growth and gene expression.

Limitations

The study does not explore the long-term effects of Ebp1 deficiency beyond one year.

Participant Demographics

Mice were of mixed genetic background (C57BL/6 and 129SvEvBrd).
