Molecular testing for the clinical diagnosis of fibrolamellar carcinoma

Historically, fibrolamellar carcinoma (FLC) has been diagnosed by analyzing the histology (microscopic anatomy) and morphology (shape, size and structure) of the tumor tissue. Frequently, that examination is combined with immunostaining for cytokeratin 7 and CD68. That immunostaining uses antibodies to see if proteins typically found in FLC are present. However, accurate diagnosis of fibrolamellar carcinoma …

CRISPR/Cas9 Engineering of Adult Mouse Liver Demonstrates that the DNAJB1-PRKACA Gene Fusion Is Sufficient to Induce Tumors Resembling Fibrolamellar Hepatocellular Carcinoma

The DNAJB1-PRKACA fusion gene is found in almost all FLC tumors. In order to determine if this gene fusion is a cause of the tumors, these researchers used a CRISPR-Cas9 technique to create a chimeric DNAJB1-PRKACA fusion gene in the livers of otherwise healthy mice. Using the CRISPR-Cas9 system, the researchers created guide RNAs that …
