Disruption of PKA RIα phase separation by the oncogenic fusion protein in FLC

Timeframe: 2021 – 2024 Goals: Determine the molecular mechanisms of FLC and identify new pharmacological agents that could lead to effective therapeutics Principal Investigator: Jin Zhang, PhD Study overview: In recent studies, the investigation team discovered that the presence of the FLC oncogenic fusion protein disrupts a membraneless organelle. They showed that loss of this …

Development and Characterization of Patient-derived Models of Fibrolamellar Carcinoma

Timeframe: 2023 – 2025 Goal: Evaluate selective inhibitors of polo-like kinase 1 (PLK1) for effectiveness in human models of FLC Principal Investigator: Taran Gujral, PhD Study overview: Abormal cell signaling by the DNAJ-PKAc fusion protein kinase drives the uncontrolled growth of fibrolamellar carcinoma. Thus far, however, drugs that inhibit the fusion kinase also block the …

Elucidation of nuclear-mitochondrial signaling by DNAJ-PKAc to define targeted vulnerabilities in FLC

Timeframe: 2022 – 2025 Goals: Identifying how the DNAJ-PKAc/SIK/p300 program controls mitochondrial function and define how these abnormal mitochondria affect the metabolism of FLC cells Principal Investigator: Nabeel M. Bardeesy, PhD Study overview: Signals that control the growth and metabolism of cells often are relayed through a series of reactions in which proteins are sequentially …

Creating a fibrolamellar cancer dependency map

Timeframe: 2020 – 2023 Goal: Create a comprehensive list of potential drug targets for FLC Principal Investigator: Jesse Boehm, PhD Study overview: This project is part of the Broad Institute’s Rare Cancer Dependency Map Initiative. The project has three main goals to identify potential FLC therapeutics: If fully successful, this effort will nominate high priority …

X-Chem collaborative effort

Timeframe: 2024 – 2025 Study overview: Since the discovery in 2014 of the fusion gene (DNAJB1-PRKACA) that drives fibrolamellar carcinoma (FLC), a drug that would selectively inhibit or destroy the chimeric protein (DNAJ-PKAc) encoded by that gene has been considered a “holy grail” for FLC therapy. Such a drug must effectively target DNAJ-PKAc, while only …

Targeting CDK7 in Fibrolamellar Carcinoma (FLC)

Timeframe: 2024 – 2026 Goal: Determine if targeting CDK7 could be a useful treatment approach for FLC. Principal Investigator: Sean Ronnekleiv-Kelly, MD Study overview: Unregulated proliferation of cells is a hallmark of cancer. In other words, cancer cells continue to divide and increase in number when normal cells would stop dividing. A family of 20 …

Novel synergistic combination therapy in fibrolamellar carcinoma

Timeframe: 2022 – 2023 Goal: Knock-out gene targets in a mouse model of FLC to identify potentially effective drug combinations for patients with advanced FLC Principal Investigator: Sean Ronnekleiv-Kelly, MD Study overview: This study will apply an innovative gene-editing based technology (genome-wide CRISPR knockout screen) on a mouse cellular model to screen all possible cancer …
