Modeling Breast Cancer via an Intraductal Injection of Cre-expressing Adenovirus into the Mouse Mammary Gland

Overview

This protocol describes a novel approach for modeling breast cancer through the intraductal injection of Cre-expressing adenovirus into mouse mammary glands. This method enables specific manipulation of oncogenic events in a controlled manner.

Key Study Components

Area of Science

• Breast cancer research
• Mouse model development
• Oncogenic manipulation

Background

• Current methods for modeling breast cancer often require extensive mouse breeding.
• There is a need for techniques that allow for cell-type specific modeling.
• This protocol aims to address these challenges.
• It focuses on the use of adenoviral vectors for targeted gene manipulation.

Purpose of Study

• To create a new mouse model that mimics human breast cancer development.
• To facilitate research on different subsets of mammary epithelial cells.
• To provide a method that reduces the need for complex breeding strategies.

Methods Used

• Preparation and maintenance of floxed mice.
• Administration of anesthesia and analgesia prior to surgery.
• Intraductal injection of Cre-expressing adenovirus.
• Monitoring of surgical procedures for safety and efficacy.

Main Results

• Successful generation of breast cancer mouse models.
• Demonstrated cell-type specific manipulation of oncogenic events.
• Reduced complexity in model generation compared to traditional methods.
• Potential for further studies on breast cancer progression.

Conclusions

• This protocol provides a novel approach to breast cancer modeling.
• It allows for precise control over oncogenic events in specific cell types.
• The method can enhance understanding of breast cancer biology.
