Neuron extensions with low NO

How do neurons decide when to grow and when to stop growing?

The Homebody RNA

Why does some RNA stay in the nucleus rather than rushing off to make proteins? 

PYK2 (red) and the cell-surface receptor (green) that triggers the cellular transition to a pro-metastatic state are found in the same membrane compartment (yellow) from which the transition signal is transmitted

A signal stuck in the “on” position may hasten metastasis in certain breast cancers

Cultured colorectal cancer cells. Top: Cells that have become resistant to certain forms of chemotherapy and continue to thrive. Bottom: The same cells, which have had the LIP gene inserted and are then treated with chemotherapy drugs

What makes cancer cells survive chemotherapy?

Normal human colonic crypts. SMOC-2 expression (red) in the colonic stem cells demonstrates that these cells are localized in the bottoms of the crypts. Bars represent 100 micrometers (left) and 50 micrometers (right)

Some tumor cells in the advanced stages of colorectal cancer adopt a...
