In this study, researchers reviewed the detailed medical records of 262 patients under age 20 diagnosed with liver cancers, assembled from 19 different hospitals and covering the years 1990 to 2017. This represents the richest available source of data on these pediatric liver cancers. They found that 119 (45%) of the tumors had been classified …
Nearly all FLC tumors carry the fusion gene DNAJB1-PRKACA and the expressed protein chimera DNAJ-PKAc which is believed to be the driver of FLC formation. However, to identify potential new therapies for FLC, it is important to understand the specific mechanisms that drive the progression of the disease. In a previous study, the Sethupathy lab …
In this study, published in March 2024, the researchers looked at how a patient’s immune system responds to the protein produced by the fusion of the genes DNAJB1 and PRKACA in FLC. Specifically, the team aimed to understand how the immune system’s “killer” T cells (CD8s) respond to this mutation and evaluate T cell receptors …
This study sequenced the DNA from FLC tumors and compared the results to the DNA from non-cancerous tissue from the same patients to identify the specific mutations that had occurred in the cancer. In the 10 samples examined, the only consistent mutation was the DNAJB1-PRKACA fusion gene. Since the only consistent mutation found was the …
