6mer Seed Toxicity

A tool to look up the toxicity of any siRNA, shRNA or miRNA with known 6mer seed sequence.


This site was created in collaboration with the Peter Lab at the Feinberg School of Medicine of Northwestern University.

It allows to determine the activity of any siRNA, shRNA, or miRNA to be toxic through induction of DISE (death induced by survival gene elimination) in human (HeyA8 - ovarian, H460 - lung and H4 - brain) and mouse (M565 - liver, 3LL - lung and GL261 - brain) cancer cell lines.

The app is entirely static, hosted with Github Pages and all data filtering and download file generation occurs locally without any server requests made apart from the initial browser request.

How to use

Please refer to the sections at the bottom of the live website.
