Decoding the Cancer Mechanisms of Fibrolamellar Carcinoma: How DNAJB1-PRKACA drives Cancer Growth Critical cellular functions such as growth, survival, and communication with other cell types in the body are mediated by networks of proteins. These networks are normally tightly regulated by signaling molecules, which serve as on/off switches. Genetic changes can cause these signaling molecules …

Rare tumors contribute significantly to the burden of cancer in the United States, yet are often poorly understood and have inadequate research support. To address this situation, the National Cancer Institute’s (NCI) My Pediatric and Adult Rare Tumor Network (MyPART) was developed. MyPART’s goals include connecting participants and investigators through shared infrastructure and networks; accelerating …

While the significance of the DNAJB1-PRKACA fusion gene in fibrolamellar carcinoma has been established and validated, the role of microRNAs (miRNAs) in FLC remains unclear. MicroRNAs have been implicated as drivers in many diseases including a variety of cancers. This study analyzed small RNA sequencing data to identify dysregulated miRNAs in FLC tumors and identified …

This study was the first published research effort that identified the DNAJB1-PRKACA chimeric transcript in fibrolamellar carcinoma tumors. By performing RNA sequencing on tumor and healthy tissue samples, a chimeric transcript was discovered that had not been previously reported in the literature. This fusion transcript arises due to a ~400-kilobase deletion on chromosome 19.  In …

Due to limited knowledge about the immune response to FLC, developing effective immunotherapy is challenging for the disease. In this study, the team investigated the immune environment of fibrolamellar carcinoma (FLC) using several techniques including multiplex immunohistochemistry and flow cytometry. Key findings of the effort include: Implications: The key takeaway of this study is that …
