Sequencing two Tyr::CreER^T2 transgenic mouse lines

Area of Science:

• Genetics and Genomics
• Developmental Biology
• Cancer Biology

Background:

• The Cre/loxP system enables targeted gene manipulation in biological research.
• The Tyr::CreER^T2 mouse model allows tamoxifen-inducible Cre recombinase activity in melanocytes.
• Studying melanocyte transformation often utilizes transgenic models for genetic control.

Purpose of the Study:

• To identify the genomic integration sites of two independent Tyr::CreER^T2 transgenic mouse models.
• To develop accurate PCR-based genotyping methods for these models.
• To compare the advantages of the characterized Tyr::CreER^T2 mouse models.

Main Methods:

• Whole genome sequencing (WGS) of genomic DNA from Tyr::CreER^T2 mouse models.
• Bioinformatic analysis to pinpoint transgene integration sites within the C57BL/6 genome.
• Design and validation of PCR primers for efficient and accurate genotyping.

Main Results:

• The specific integration sites for both Tyr::CreER^T2 transgenes were successfully identified.
• Validated PCR primers provide a reliable method for distinguishing transgenic mice.
• Characterization facilitates informed selection between the two available mouse models.

Conclusions:

• Precise knowledge of transgene integration sites is crucial for characterizing transgenic models.
• The developed genotyping strategy enhances the utility of Tyr::CreER^T2 mice for melanocyte research.
• This study provides valuable resources for researchers investigating melanocyte development and transformation.
