Developmentally programmed tankyrase activity upregulates β-catenin and licenses progression of embryonic genome activation

ABSTRACT: Embryonic genome activation (EGA) is orchestrated by an intrinsic developmental program initiated during oocyte maturation with translation of stored maternal mRNAs. Here we show that tankyrase, a poly(ADP-ribosyl) polymerase that regulates β-catenin levels, undergoes programmed translation during oocyte maturation and serves an essential role in mouse EGA. Newly translated TNKS triggers proteasomal degradation of axin, reducing targeted destruction of β-catenin and promoting β-catenin-mediated transcription of target genes, including Myc. MYC mediates ribosomal RNA transcription in 2-cell embryos, supporting global protein synthesis. Suppression of tankyrase activity using knockdown or chemical inhibition causes loss of nuclear β-catenin and global reductions in transcription and histone H3 acetylation. Chromatin and transcriptional profiling indicate that development arrests prior to the mid-2-cell stage, mediated in part by reductions in β-catenin and MYC. These findings indicate that post-transcriptional regulation of tankyrase serves as a ligand-independent developmental mechanism for post-translational β-catenin activation and is required to complete EGA.

Expression data of colon cancer COLO320DM cells and tankyrase inhibitor-resistant variant 320-IWR cells

Project description:Wnt/β-catenin signaling is activated in colorectal cancer (CRC) and is involved in CRC growth. Tankyrase, a poly(ADP-ribose) polymerase family member, destabilizes Axin and positively regulates the Wnt/β-catenin signaling. Tankyrase inhibitors efficiently suppress CRC cell proliferation. We established 320-IWR cells, which showed resistance to tankyrase inhibitor IWR-1, from human CRC COLO-320DM cells. We analyzed gene expression profile of 320-IWR cells (320IWR_1,_2) and parental COLO-320DM cells (COLO320_1,_2).

Identification of response signatures for tankyrase inhibitor treatment in tumor cell lines

Project description:Small-molecule tankyrase 1 and tankyrase 2 (TNKS1/2) inhibitors are effective anti-tumor agents in selected tumor cell lines and mouse models. Here, we characterized the response signatures and the in-depth mechanisms for the anti-proliferative effect of tankyrase inhibition (TNKSi). The TNKS1/2-specific inhibitor G007-LK was used to screen 537 human tumor cell lines and a panel of in particular TNKSi-sensitive tumor cell lines was identified. Transcriptome, proteome and bioinformatic analyses revealed the overall TNKSi-induced response signatures in the selected panel. TNKSi-mediated inhibition of WNT/β-catenin, YAP and PI3K/AKT signaling was validated and correlated with lost expression of the key oncogene MYC and impaired cell growth. Moreover, we show that TNKSi induces accumulation of TNKS1/2-containing β-catenin degradasomes functioning as central complexes interacting with YAP and AMOT proteins during attenuation of YAP signaling. These findings provide a contextual and mechanistic framework for using TNKSi in anti-cancer treatment that warrants further comprehensive preclinical and clinical evaluations.

Identification of response signatures for tankyrase inhibitor treatment in tumor cell lines

Project description:Anti-cancer treatment, using small-molecule tankyrase 1 and tankyrase 2 (TNKS1/2) inhibition (TNKSi) shows effect against selected tumor cell lines and in mouse models. Here, we characterize the responsiveness signatures and in depth mechanisms for the anti-proliferative effect of TNKSi. The TNKS1/2-specific inhibitor G007-LK was screened against 537 human tumor cell lines, and a panel of in particular TNKSi-sensitive tumor cell lines was identified. Transcriptome, proteome and bioinformatic analyses classified the overall TNKSi-induced response signatures in the selected panel. Prediction of TNKSi-mediated inhibition of WNT/β-catenin, YAP and PI3K/AKT signaling was validated and correlated with lost expression of the key oncogene MYC and impaired cell growth. Moreover, we show that TNKSi, when attenuating YAP signaling, induces accumulation of TNKS1/2-containing β-catenin degradosomes functioning as central complexes interacting with YAP and AMOT proteins. The findings provide a contextual and mechanistic framework for TNKSi in cancer cell lines rationalizing further comprehensive preclinical and clinical evaluations.

A Tissue-Specific Tankyrase Inhibitor Drives Key Developmental and Oncogenic Pathways

Project description:Tissue-specific regulation of WNT and YAP/TAZ signaling is critical for optimal organismal growth, development, and maintenance. Uncontrolled activity often leads to developmental abnormalities and aggressive cancers. Tankyrase (TNKS) is a poly-ADP-ribose polymerase (PARP) that controls both WNT and YAP/TAZ signaling. However, it is unclear how TNKS activity is regulated in a tissue and cell-type specific manner. Here, we identified the previously uncharacterized prostate-associated gene 4 (PAGE4) as a tissue-specific TNKS inhibitor. Structural and biochemical studies revealed that mechanistically PAGE4 inhibits TNKS through hijacking TNKS substrate binding pockets leading to the stabilization of TNKS substrates. In vitro cell culture and in vivo zebrafish and transgenic mouse model studies showed that PAGE4 is a potent inhibitor of TNKS and WNT signaling. Interestingly, PAGE4 is physiologically restricted to expression in select tissues and cell types, including WNT producing prostatic fibroblasts where spatiotemporal regulation of WNT signaling is critical for proper organ development. Surprisingly, PAGE4 is aberrantly expressed in hepatocellular carcinomas that bypass TNKS through mutant CTNNB1 driven WNT signaling. In vitro and in vivo tumorigenic studies revealed that PAGE4 initially function as a tumor suppressor through inhibition of WNT signaling, but upon CTNNB1 mutation becomes an oncogenic driver through YAP/TAZ signaling. Thus, we establish PAGE4 as a robust tissue-specific TNKS inhibitor that physiologically coordinates developmental WNT signaling, but genetic aberration during cancer progression re-wire PAGE4 into pro-oncogenic YAP/TAZ pathway.

HGPalmer-PDX-NVP-TNKS656

Project description:Strong activation of the oncogenic Wnt/beta-catenin pathway is a main mechanism of resistance to FOXO3a-induced apoptosis promoted by PI3K and AKT inhibitors in colorectal cancer (CRC). Reducing Wnt/beta-catenin activity would sensitize colorectal tumors to these inhibitors. However, no Wnt/beta-catenin signaling inhibitor has proven clinical potential yet. Recently, inhibitors that block tankyrases were shown to reduce colon cancer cell proliferation by decreasing nuclear beta-catenin. We aim to identify determinants of response to these novel Wnt-inhibitors. Therefore, we treated in vivo three different patient-derived xenograft models (PDX; P2, P5 and P30) growing subcutaneously in NOD SCID mice with the novel tankyrase inhibitor NVP-TNKS656.

Human Tankyrases TAP-LC-MSMS - Proteomic Analysis of the Human Tankyrase Protein Interaction Network Reveals Its Role in Pexophagy

Project description:Tankyrase 1 (TNKS1) and tankyrase 2 (TNKS2) belong to the poly(ADP-ribose) polymerase (PARP) family of proteins, which use NAD+ to modify substrate proteins with ADP-ribose modifications. Tankyrases are implicated involving in multiple cellular functions, including the telomere length control, Wnt/b-catenin pathway regulation, glucose uptake and cell cycle regulation. Emerging evidences reveal the pathological relevance of tankyrase in diseases and propose these two key enzymes as potential drug targets. However, the cellular functions and regulatory machineries of tankyrases are still largely unknown. Through this proteomic analysis, we not only defined the protein-protein interaction map for the tankyrases which revealed 100~150 high confident interacting proteins for tankyrases in various cellular functions, but also uncovered the novel regulating function of tankyrase in peroxisome homeostasis.

Gene expression profiling of tankyrase-inhibited mouse articular chondrocytes

Project description:Osteoarthritis (OA) is a prevalent degenerative disease, which involves progressive and irreversible destruction of cartilage matrix. Despite efforts to reconstruct cartilage matrix in osteoarthritic joints, it has been a difficult task as adult cartilage exhibits marginal repair capacity. Here we report the identification of tankyrase as a regulator of the cartilage anabolism axis based on systems-level factor analysis of mouse reference populations. Tankyrase inhibition drives the expression of a cartilage-signature matrisome and elicits a transcriptomic pattern that is inversely correlated with OA progression. Furthermore, tankyrase inhibitors ameliorate surgically-induced OA in mice, and stem cell transplantation coupled with tankyrase knockdown results in superior regeneration of cartilage lesions. Mechanistically, the pro-regenerative features of tankyrase inhibition are mainly triggered by uncoupling SOX9 from a poly(ADP-ribosyl)ation (PARylation)-dependent protein degradation pathway. Our findings provide insights into the development of future OA therapies aimed at reconstruction of articular cartilage.
