How do tumors and their host tissues shape the earliest events of brain metastasis?

Chaitali Khan

About

Chaitali Khan investigates how cancer cells interact with the tissues around them, using Drosophila to study early events in brain metastasis. Her work connects molecular genetics, cell biology, and light and electron microscopy to reveal the cellular dynamics of the tumor microenvironment.

At NIH, she developed an adult-fly allograft transplantation method for metastasis studies and investigated the pro-invasive role of macrophages in the brain metastatic niche. Her earlier research examined cell competition, p53 and proteotoxic responses, and the links between DNA damage and tissue homeostasis.

Expertise

Drosophila disease models, tumor–host interactions, cell competition, molecular genetics, CRISPR, light and electron microscopy
