Super-resolution microscopy reveals how a cancer drug triggers cellular breakdown
Researchers at the University of Cincinnati used super-resolution microscopy to observe how the cancer drug sunitinib fragments mitochondrial and endoplasmic reticulum networks in cells. This study provides new insights into how drug localization within a cell influences therapeutic effectiveness.
Why it matters
Understanding the intracellular behavior of drugs can lead to more effective cancer treatments and a better grasp of potential side effects.

Add as preferred source Sunitinib treatment changes mitochondrial and endoplasmic reticulum (ER) morphology in HeLa cells. In mitochondria (left, magenta) and ER (right, red), untreated 'control' cells display extensive networks that spread throughout the cell. After exposure to sunitinib, these networks became increasingly fragmented and disorganized. Credit: Yadev et al. Cancer drugs are often designed to block specific molecular targets, but what happens after they enter a cell is not always well understood. A new study published in Biophotonics Discovery demonstrates how advanced imaging technology can help answer that question.
