Frequently Asked Questions

What is the significance of HRAS G12V in cancer research?

HRAS G12V is a common mutation that drives oncogenesis, making it a critical target for understanding cancer mechanisms.

Why are zebrafish used as a model organism?

Zebrafish are transparent during early development, allowing for real-time imaging of cellular processes in vivo.

What are preneoplastic cells?

Preneoplastic cells are abnormal cells that have the potential to develop into cancer but are not yet malignant.

How does live imaging contribute to cancer research?

Live imaging allows researchers to observe cellular interactions and behaviors in real-time, providing insights into cancer progression.

What role do innate immune cells play in cancer?

Innate immune cells can influence tumor development and progression, either promoting or inhibiting cancer growth.
