Hypothesis
What are the molecular pathways driving alveolar sacculation in T1α null mice?
Conclusion
The study identified several candidate genes significantly altered in T1α null lungs, which may play roles in abnormal alveolar sac formation.
Supporting Evidence
- Altered expression of genes related to cell-cell interaction was observed in T1α(-/-) at E18.5.
- At term, several genes that regulate the cell cycle were down-regulated in T1α(-/-) lungs.
- PCNA levels were increased and p21 levels were decreased in T1α(-/-) lungs at term.
Takeaway
Mice without the T1α gene have trouble forming normal lung sacs, which are important for breathing, and this study found changes in many genes that might explain why.
Methodology
Expression microarrays were used to analyze gene expression in T1α null and wild-type mice lungs at different developmental stages.
Limitations
The ability to detect significant gene changes at term was limited by the smaller sample size.
