Hypothesis
The ratio of THRα1 to THRα2 isoforms is critical for transcriptional regulation in various tissues and may be abnormal in thyroid hormone resistance syndromes.
Conclusion
The pCMV-THRA-RFP-EGFP splicing detector allows for the visualization and quantification of THRA1 and THRA2 splicing isoforms in living cells.
Supporting Evidence
- The pCMV-THRA-RFP-EGFP splicing detector can quantify the ratio of THRA1 to THRA2 in living cells.
- Live-cell imaging showed different expression patterns of THRA isoforms in COS1 and N2A cells.
- ASO treatment effectively blocked THRA2 splicing, confirming the tool's utility in detecting splicing perturbations.
Takeaway
Scientists created a special tool that helps them see and measure two important parts of a protein that helps control how our body uses thyroid hormones.
Methodology
The study involved creating a plasmid that expresses RFP and EGFP as proxies for THRA1 and THRA2, respectively, and testing it in COS1 and N2A cells.
Limitations
The relatively large size of the plasmid may hinder transfection efficiency and cell survival.
