Exploring the Spread of Cancer to the Brain
Researchers leveraged microfluidic chips to study how cancer cell migrates to the blood-brain niche. Results are published in the journal Advanced NanoBiomed Research.
Using breast cancer cell lines, they found that Dkk-1, a cytokine released by the astrocytes, triggers the cancer cells to migrate. Dkk-1 is known to play a role in in Wnt signaling, a key signaling pathway linked to cancer progression.
Is There a Connection Between Brain Niche Cells and Cancer Cells?
"Crosstalk between brain niche cells and cancer cells allows invading cancer cells to permeate the blood-brain barrier. Reducing Dkk-1 levels near invading tumor cells might disrupt this crosstalk and prevent brain metastases," said corresponding author Christopher R. Oliver, Ph.D., a post-doctoral fellow in the Merajver Lab.‘Deciphering how cancer cells thrive or fail in the brain niche sheds insights into new therapies aiming molecular processes. ’
