Hypothesis

Does Int6 play a role in MEK-ERK signaling during zebrafish development?

Conclusion

Int6 is essential for normal craniofacial development in zebrafish and modulates MEK-ERK signaling.

Supporting Evidence

  • Int6 is required for normal expression of MEK1 protein in human cells.
  • Loss of Int6 or Mek signaling causes defects in craniofacial development.
  • Int6 and Erk-signaling have overlapping domains of tissue expression.

Takeaway

Int6 helps zebrafish grow properly, especially their faces, by working with a signaling pathway that is also important in cancer.

Methodology

The study used zebrafish models and various genetic and chemical-genetic approaches to analyze Int6 function.

Limitations

The study primarily focuses on zebrafish, which may not fully represent human biology.
