Welcome to the Wangensteen Lab


Our lab is conducting exciting research on the genetics of liver repopulation and hepatocellular carcinoma (HCC). We have developed two highly innovative in vivo genetic screening paradigms to elucidate genetic pathways involved in carcinogenesis and liver repopulation in the setting of toxic injury. We aim to discover pathways that lead to drug sensitivity and resistance in HCC.  One of our assays involves CRISPR activation screening in vivo in the liver, the first-ever use of this type of screening in live mice.

In press, editorial by Yin, Dingzi and Wangensteen, KJ, "Incapacitated Capicua in sorafenib-resistant HCC" at Cellular and Molecular Gastroenterology and Hepatology

Nov, 2019:

Now published, the largest ever in vivo screen, conducted by Adam Zahm and colleagues to identify miRNA interactions in liver repopulation. This paper has beautiful graphics to depict the technology and results. Check it out:

Wangensteen Lab had a strong showing at the 2019 AASLD Liver meeting!

  • Congrats Morgan on receiving the Professor Margit Hamosh Memorial Travel Award for the most outstanding abstract on hepatocellular carcinoma research for The Liver Meeting for her abstract entitled, "LXR agonism potentiates Sorafenib activity in HCC by inducing metabolic stress". She gave an excellent oral presentation.
  • Congrats Julia Kieckhaefer for presenting her poster of distinction, "Identification of effectors of TNFA signaling that modulate liver repopulation by high throughput CRISPRA screening," which received a lot of interest.

Oct, 2019: 

Congratulations Amber on publishing this interesting work to examine the changes in chromatin in the repopulating liver:
