    Abstract Summary: Tumor-associated myeloid cells modulate the tumor microenvironment and affect tumor progression. Type I interferon (IFN-I) has multiple effects on tumors and immune response, and ubiquitin-specific peptidase 18 (USP18) functions as a negative regulator of IFN-I signal transduction. This study aims to examine the function of IFN-I in myeloid cells during tumor progression. Here, we show that deletion of USP18 in myeloid cells suppresses tumor progression. Enhanced IFN-I signaling and blocked USP18 expression prompt downregulation of colony stimulating factor 1 receptor (CSF1R) and polarization of tumor-associated macrophages toward pro-inflammatory phenotypes. Further in vitro experiments reveal that downregulation of CSF1R is mediated by ubiquitin-proteasome degradation via E3 ligase neural precursor cell-expressed, developmentaly downregulated 4 (NEDD4) and the IFN-induced increase in ubiquitin E2 ubiquitin-conjugating enzyme H5. USP18 impairs ubiquitination and subsequent degradation of CSF1R by interrupting NEDD4 binding to CSF1R. These results reveal a previously unappreciated role of IFN-I in macrophage polarization by regulating CSF1R via USP18 and suggest targeting USP18 in myeloid-lineage cells as an effective strategy for IFN-based therapies.

    Abstract The transcription factor RUNX1 is a master regulator of hematopoiesis and is frequently mutated in myeloid malignancies. Mutations in its runt homology domain (RHD) frequently disrupt DNA binding and result in loss of RUNX1 function. However, it is not clearly understood how other RUNX1 mutations contribute to disease development. Here, we characterize RUNX1 mutations outside of the RHD. Our analysis of patient datasets revealed that mutations within the C-terminus frequently occur in hematopoietic disorders. Remarkably, most of these mutations were nonsense or frameshift and predicted to be exempt from nonsense mediated mRNA decay. Therefore, this class of mutation is projected to produce DNA-binding proteins that contribute to pathogenesis in a distinct manner. To model this, we introduced the RUNX1R320* mutation into the endogenous gene locus and demonstrated the production of RUNX1R320* protein. Expression of RUNX1R320* resulted in the disruption of RUNX1 regulated processes such as megakaryocytic differentiation through a transcriptional signature different from RUNX1 depletion. To understand the underlying mechanisms, we utilized Global RNA Interactions with DNA by deep sequencing (GRID-seq) to examine enhancer-promoter connections. We identified wide-spread alteration of enhancer-promoter networks within RUNX1 mutant cells. Additionally, we uncovered enrichment of RUNX1R320* and FOXK2 binding at the MYC super enhancer locus, significantly upregulating MYC transcription and signaling pathways. Together, our study demonstrates that most RUNX1 mutations outside the DNA binding domain are not subject to nonsense mediated decay, producing protein products that act in concert with additional cofactors to dysregulate hematopoiesis through mechanisms distinct from that induced by RUNX1 depletion.

    Abstract While immunotherapy has emerged as a breakthrough cancer therapy, it is only effective in some patients, indicating the need of alternative therapeutic strategies. Induction of cancer immunogenic cell death (ICD) is one promising way to elicit potent adaptive immune responses against tumor-associated antigens. Type I interferon (IFN) is well known to play important roles in different aspects of immune responses, including modulating ICD in anti-tumor action. However, how to expand IFN effect in promoting ICD responses has not been addressed. Here we show that depletion of ubiquitin specific protease 18 (USP18), a negative regulator of IFN signaling, selectively induces cancer cell ICD. Lower USP18 expression correlates with better survival across human selected cancer types and delays cancer progression in mouse models. Mechanistically, nuclear USP18 controls the enhancer landscape of cancer cells and diminishes STAT2-mediated transcription complex binding to IFN-responsive elements. Consequently, USP18 suppression not only enhances expression of canonical IFN-stimulated genes (ISGs), but also activates the expression of a set of atypical ISGs and NF-κB target genes, including genes such as Polo like kinase 2 (PLK2), that induce cancer pyroptosis. These findings may support the use of targeting USP18 as a potential cancer immunotherapy.

    Abstract Type I IFNs (α, β, and others) are a family of cytokines that are produced in physiological conditions as well as in response to the activation of pattern recognition receptors. They are critically important in controlling the host innate and adaptive immune response to viral and some bacterial infections, cancer, and other inflammatory stimuli. However, dysregulation of type I IFN production or response can contribute to immune pathologies termed "interferonopathies", pointing to the importance of balanced activating signals with tightly regulated mechanisms of tuning this signaling. Here, we summarize the recent advances of how type I IFN production and response are controlled at multiple levels of the type I IFN signaling cascade.

    Abstract The oncogenic role of EGFR in many tumors has attracted a great deal of attention in the recent years and initiated the development of several potent EGFR inhibitors, which are used clinically for cancer treatment. However, the current therapeutic inhibition of EGFR signaling is limited to monoclonal antibodies that bind to the EGFR extracellular domain or tyrosine kinase inhibitors that block EGFR kinase activation directly. Despite the great promise of these inhibitors, a certain percentage of patients develop resistance to these therapies, highlighting the necessity for alternative therapeutic strategies based on our most current knowledge of the mechanisms of EGFR signaling. We recently reported that Plakofilin-2 (PKP2) is a novel ligand-independent cytoplasmic activator of EGFR signaling. Here we focus on recent studies demonstrating important roles of intracellular EGFR activators, and propose targeted disruption of these activators as a novel avenue of therapeutic intervention to inhibit EGFR-mediated cancer development.

    Abstract Cells use molecular circuits to interpret and respond to extracellular cues, such as hormones and cytokines, which are often released in a temporally varying fashion. In this study, we combine microfluidics, time-lapse microscopy, and computational modeling to investigate how the type I interferon (IFN)-responsive regulatory network operates in single human cells to process repetitive IFN stimulation. We found that IFN-α pretreatments lead to opposite effects, priming versus desensitization, depending on input durations. These effects are governed by a regulatory network composed of a fast-acting positive feedback loop and a delayed negative feedback loop, mediated by upregulation of ubiquitin-specific peptidase 18 (USP18). We further revealed that USP18 upregulation can only be initiated at the G1/early S phases of cell cycle upon the treatment onset, resulting in heterogeneous and delayed induction kinetics in single cells. This cell cycle gating provides a temporal compartmentalization of feedback loops, enabling duration-dependent desensitization to repetitive stimulations.

    Abstract As a defense mechanism against infection, host cells have evolved sensor molecules which detect pathogen components directly and induce protective responses against the infection. TLRs, well known receptors, recognize a pathogen on the surface of cells or endosome/lysosome. Many pathogens penetrate into cytoplasm, in where non-TLR sensors recognize pathogen components including double-stranded RNA (dsRNA). On the downstream of each sensor, a variety of functional signaling molecules are activated to produce various cytokines upon the microbial invasion to induce host defense responses. Because that cytokines produced to regulate the host defense responses are known to affect cell proliferation also, the level of these molecules are needed to be controlled tightly, which means requisites of negative regulation of the signaling activated by pathogen after the completion of proper immune responses. Recent studies suggest important roles of some ubiquitin systems in this regulation. Here we focus, in particular, ubiquitin conjugation to signaling molecules by virus activation and like to show how ubiquitin signaling plays roles in this regulation by introducing some recent works.

    Abstract Large-scale chromosomal translocations are frequent oncogenic drivers in acute myeloid leukemia (AML). These translocations often occur in critical transcriptional/epigenetic regulators and contribute to malignant cell growth through alteration of normal gene expression. Despite this knowledge, the specific gene expression alterations that contribute to the development of leukemia remain incompletely understood. Here, through characterization of transcriptional regulation by the RUNX1-ETO fusion protein, we have identified Ras-association domain family member 2 (RASSF2) as a critical gene that is aberrantly transcriptionally repressed in t(8;21)-associated AML. Re-expression of RASSF2 specifically inhibits t(8;21) AML development in multiple models. Through biochemical and functional studies, we demonstrate RASSF2-mediated functions to be dependent on interaction with Hippo kinases, MST1 and MST2, but independent of canonical Hippo pathway signaling. Using proximity-based biotin labeling we define the RASSF2-proximal proteome in leukemia cells and reveal association with Rac GTPase-related proteins, including an interaction with the guanine nucleotide exchange factor, DOCK2. Importantly, RASSF2 knockdown impairs Rac GTPase activation, and RASSF2 expression is broadly correlated with Rac-mediated signal transduction in AML patients. Together, these data reveal a previously unappreciated mechanistic link between RASSF2, Hippo kinases, and Rac activity with potentially broad functional consequences in leukemia.
