Gene expression data of APC-mutated colorectal cancer patient-derived cells treated with tankyrase inhibitors

Project description:Tankyrase, a poly(ADP-ribose) polymerase family member, regulates multiple cellular processes. Tankyrase inhibitors efficiently suppress APC-mutated colorectal cancer (CRC) cell proliferation. To examine the mechanism of anti-proliferative effect of tankyrase inhibitors (G007LK and RK582), we analyzed gene expression profiles of patient-derived APC-mutated CRC cells (JC21 and JC475) left untreated or treated with 0.3 µM G007LK or RK582 for 24 h by cDNA microarray analysis.

BET protein-dependent E2F pathway confers bell-shaped type resistance to tankyrase inhibitors in APC-mutated colorectal cancer [RNA-seq]

Project description:In colorectal cancer (CRC), WNT/β-catenin signaling is aberrantly activated mainly by loss-of-function mutations in adenomatous polyposis coli (APC) and is involved in tumor progression. Tankyrase inhibitors, which suppress WNT/β-catenin signaling, are under pre-clinical and clinical trials, while their resistance mechanisms remain unclear. In this study, we established tankyrase inhibitor-resistant CRC cells, JC73-RK100, from APC-mutated patient-derived CRC cells. JC73-RK100 cells and several CRC cells were sensitive to tankyrase inhibitors at low concentrations but were resistant at high concentrations (i.e., bell-shaped dose response: BSDR). Mechanistically, tankyrase inhibitors at high concentrations promoted BRD3/4-dependent E2F target gene transcription and over-activated cell cycle progression in the BSDR cells. BET inhibitors canceled the bell-shaped dose response to tankyrase inhibitors. Taken together, these observations suggest that combination of tankyrase and BET inhibitors would be a useful therapeutic approach to overcome a subset of resistance to tankyrase inhibitors.

Tankyrase inhibitors efficiently suppress colorectal cancer (CRC) cell proliferation. To examine the mechanism of anti-proliferative effect of tankyrase inhibitors (G007LK and RK582), we analyzed gene expression profiles of patient-derived CRC cells (JC11 and JC494) left untreated or treated with 0.3 µM G007LK or RK582 for 24 h by cDNA microarray analysis.

Tankyrase inhibitors target colorectal cancer stem cells via AXIN-dependent downregulation of c-KIT tyrosine kinase

Project description:Tankyrase, a poly(ADP-ribose) polymerase family member, destabilizes Axin and positively regulates the Wnt/β-catenin signaling. We demonstrated that tankyrase inhibitors can target the colorectal cancer stem-like cells. Tankyrase inhibitors efficiently suppress colorectal cancer stem-like cell proliferation via AXIN-dependent manner. We sorted CD44-positive COLO-320DM cells, which showed a characteristic of CSCs and were targeted by tankyrase inhibitors. We analyzed gene expression profile of CD44-positive cells (CD44-positive 01, 02, 03) and CD44-negative cells (CD44-negative 01, 02, 03).

USP7 is a tumor-specific WNT activator for APC-mutated colorectal cancer by mediating B-catenin deu

Project description:The tumor suppressor gene adenomatous polyposis coli (APC) is mutated in most colorectal cancers (CRC) resulting in constitutive Wnt activation. To understand the Wnt-activating mechanism of APC mutation, we applied CRISPR/Cas9 technology to engineer various APC-truncated isogenic lines. We find that the β-catenin inhibitory domain (CID) in APC represents the threshold for pathological levels of Wnt activation and tumor transformation. Mechanistically, CID-deleted APC truncation promotes β-catenin deubiquitination through reverse binding of β-TrCP and USP7 to the destruction complex. USP7 depletion in APC-mutated CRC inhibits Wnt activation by restoring β-catenin ubiquitination, drives differentiation and suppresses xenograft tumor growth. Finally, the Wnt-activating role of USP7 is specific to APC mutations, thus can be used as tumor-specific therapeutic target for most CRCs.
