Macrophages infiltrate and establish in developing organs from an early stage, often before these have become vascularised. Similarly, leukocytes in general can quickly migrate through tissues to any site of wounding. This unique capacity is rooted in their characteristic amoeboid motility, the genetic basis of which is poorly known. Trim33 (Tif1-γ), a nuclear protein that associates with specific DNA binding transcription factors to modulate gene expression, has been found mainly involved in hematopoiesis and gene regulation by TGF-ß...

Dermatomyositis (DM) is an autoimmune disorder associated with a dysregulation of immune homeostasis of both the innate and adaptive immune system. Earlier data suggested that these two arms of the immune system interconnect in DM. In the current study, we analysed the association of autoantigen expression [adaptive system components: Mi2, transcriptional intermediary factor (TIF)1γ, small ubiquitin-like modifier 1 activating enzyme subunit (SAE)1, melanoma differentiation-associated protein (MDA)5] with markers of cellular stress (innate system components: MxA, p53) in skin and muscle (immunohistology and gene expression data, respectively)...

Rearranged during transfection (RET) fusion-positive non-small cell lung cancer (NSCLC) accounts for approximately 1-2% of all NSCLCs. To date, RET fusions that involve at least six fusion partners in NSCLC, such as KIF5B, CCDC6, NCOA4, TRIM33, CLIP1, and ERC1, have been identified. Recent clinical trials for RET fusion-positive NSCLC using vandetanib or cabozantinib demonstrated positive clinical response and considerable differential activities for RET inhibitors among fusion partners. Alectinib, an approved ALK inhibitor, is reported to inhibit KIF5B-RET and CCDC6-RET...

Tripartite motif containing 33 (TRIM33) functions both as a positive and negative regulator of the TGF-β/BMP pathway in tumors; however, its effect and mechanism during osteoblast proliferation and differentiation, which involves the TGF-β/BMP pathway is not defined. In this study, we used mouse C3H10T1/2 mesenchymal stem cell line and MC3T3-E1 preosteoblasts to investigate the role of TRIM33 during this process. The results demonstrated that the expression of TRIM33 increased during the differentiation. Moreover, the overexpression or knockdown of TRIM33 resulted in both an augmentation or decrease in osteoblast differentiation, which were measured by the expression of alkaline phosphatase (ALP) at the mRNA level, both Runt-related transcription factor 2 (Runx2) and osteocalcin (OCN) at the protein level, and the formation of mineral modules...

The tripartite motif (TRIM) family of proteins plays important roles in innate immunity and antimicrobial infection. None of these proteins has been shown to directly regulate transcription of genes in monocyte/macrophage except TRIM33 that we have recently shown to be a macrophage specific transcriptional inhibitor of Ifnb1. Using ChIP-seq analyses, we now report that TRIM33 is bound to two fold more genes in immature than in mature myeloid cell lines. When located near the same genes, TRIM33 is bound to different sequences in the two cell lines suggesting a role of TRIM33 in both immature and mature myeloid cells...

Induction of DNA damage induces a dynamic repair process involving DNA repair factors and epigenetic regulators. Chromatin alterations must occur for DNA repair factors to gain access to DNA lesions and restore original chromatin configuration to preserve the gene expression profile. We characterize the novel role of CBX8, a chromodomain-containing protein with established roles in epigenetic regulation in DNA damage response. CBX8 protein rapidly accumulates at the sites of DNA damage within 30 s and progresses to accumulate until 4 min before gradually dispersing back to its predamage distribution by 15 min...

Bromodomain and extraterminal domain protein inhibitors (BETi) hold great promise as a novel class of cancer therapeutics. Because acquired resistance typically limits durable responses to targeted therapies, it is important to understand mechanisms by which tumor cells adapt to BETi. Here, through pooled shRNA screening of colorectal cancer cells, we identified tripartite motif-containing protein 33 (TRIM33) as a factor promoting sensitivity to BETi. We demonstrate that loss of TRIM33 reprograms cancer cells to a more resistant state through at least two mechanisms...

Trim33/Tif1γ (Trim33) is a member of the tripartite motif family. Using a conditional hematopoietic-specific Trim33 knock-out (Trim33(Δ/Δ)) mouse, we showed previously that Trim33 deficiency in hematopoietic stem cells leads to severe defects in hematopoiesis, resembling the main features of human chronic myelomonocytic leukemia. We also demonstrated that Trim33 is involved in hematopoietic aging through TGFβ signaling. Nevertheless, how Trim33 contributes to the terminal stages of myeloid differentiation remains to be clarified...

Transposable elements (TEs) have been active in the mammalian genome for millions of years and the silencing of these elements in the germline is important for the survival of the host. Mice carrying reporter transgenes can be used to model transcriptional silencing. A mutagenesis screen for modifiers of epigenetic gene silencing produced a line with a mutation in Trim33; the mutants displayed increased expression of the reporter transgene. ChIP-seq of Trim33 in testis revealed 9,109 peaks, mostly at promoters...

Despite its importance during viral or bacterial infections, transcriptional regulation of the interferon-β gene (Ifnb1) in activated macrophages is only partially understood. Here we report that TRIM33 deficiency results in high, sustained expression of Ifnb1 at late stages of toll-like receptor-mediated activation in macrophages but not in fibroblasts. In macrophages, TRIM33 is recruited by PU.1 to a conserved region, the Ifnb1 Control Element (ICE), located 15 kb upstream of the Ifnb1 transcription start site...

The Adenovirus E4-ORF3 protein facilitates virus replication through the relocalization of cellular proteins into nuclear inclusions termed tracks. This sequestration event disrupts antiviral properties associated with target proteins. Relocalization of Mre11-Rad50-Nbs1 proteins prevents the DNA damage response from inhibiting Ad replication. Relocalization of PML and Daxx impedes the interferon-mediated antiviral response. Several E4-ORF3 targets regulate gene expression, linking E4-ORF3 to transcriptional control...

Most mammalian transcription factors (TFs) and cofactors occupy thousands of genomic sites and modulate the expression of large gene networks to implement their biological functions. In this study, we describe an exception to this paradigm. TRIM33 is identified here as a lineage dependency in B cell neoplasms and is shown to perform this essential function by associating with a single cis element. ChIP-seq analysis of TRIM33 in murine B cell leukemia revealed a preferential association with two lineage-specific enhancers that harbor an exceptional density of motifs recognized by the PU...

Aberrant activation of β-catenin in the nucleus has been implicated in a variety of human cancers, but the fate of nuclear β-catenin is unknown. Here we demonstrate that the tripartite motif-containing protein 33 (TRIM33), acting as an E3 ubiquitin ligase, reduces the abundance of nuclear β-catenin protein. TRIM33-mediated β-catenin is destabilized and is GSK-3β or β-TrCP independent. TRIM33 interacts with and ubiquitylates nuclear β-catenin. Moreover, protein kinase Cδ, which directly phosphorylates β-catenin at Ser715, is required for the TRIM33-β-catenin interaction...

Transforming growth factor-beta3 (TGF-β3) plays a critical role in palatal epithelial cells by inducing palatal epithelial fusion, failure of which results in cleft palate, one of the most common birth defects in humans. Recent studies have shown that Smad-dependent and Smad-independent pathways work redundantly to transduce TGF-β3 signaling in palatal epithelial cells. However, detailed mechanisms by which this signaling is mediated still remain to be elucidated. Here we show that TGF-β activated kinase-1 (Tak1) and Smad4 interact genetically in palatal epithelial fusion...

UNLABELLED: Renal cell carcinoma (RCC) is the most common neoplasm of the adult kidney, and clear cell RCC (ccRCC) represents its most common histological subtype. To identify a therapeutic target for ccRCC, miRNA expression signatures from ccRCC clinical specimens were analyzed. miRNA microarray and real-time PCR analyses revealed that miR-629 expression was significantly upregulated in human ccRCC compared with adjacent noncancerous renal tissue. Functional inhibition of miR-629 by a hairpin miRNA inhibitor suppressed ccRCC cell motility and invasion...

NLRP3 is a key component of caspase-activating macromolecular protein complexes called inflammasomes. It has been found that DHX33 is a cytosolic dsRNA sensor for the NLRP3 inflammasome, which induces caspase-1-dependent production of IL-1β and IL-18 upon activation. However, how the cytosolic dsRNAs induce the interaction between DHX33 and the NLRP3 inflammasome remains unknown. In this study, we report that TRIM33, a member of the tripartite motif (TRIM) family, can bind DHX33 directly and induce DHX33 ubiquitination via the lysine 218 upon dsRNA stimulation...

Transcriptional intermediary factor 1 gamma (Tif1γ) (Ectodermin/PTC7/RFG7/TRIM33) is a transcriptional cofactor with an important role in the regulation of the TGFβ pathway. It has been suggested that it competes with Smad2/Smad3 for binding to Smad4, or alternatively that it may target Smad4 for degradation, although its role in carcinogenesis is unclear. In this study, we showed that Tif1γ interacts with Smad1/Smad4 complex in vivo, using both yeast two-hybrid and coimmunoprecipitation assays. We demonstrated that Tif1γ inhibits transcriptional activity of the Smad1/Smad4 complex through its PHD domain or bromo-domainin pancreatic cells by luciferase assay...

Uncovering how a new gene acquires its function and understanding how the function of a new gene influences existing genetic networks are important topics in evolutionary biology. Here, we demonstrate nonconservation for the embryonic functions of Drosophila Bonus and its newest vertebrate relative TIF1-γ/TRIM33. We showed previously that TIF1-γ/TRIM33 functions as an ubiquitin ligase for the Smad4 signal transducer and antagonizes the Bone Morphogenetic Protein (BMP) signaling network underlying vertebrate dorsal-ventral axis formation...

UNLABELLED: Head and neck squamous cell carcinoma (HNSCC) is the sixth most common type of cancer worldwide. The increasing amount of genomic information on human tumors and cell lines provides more biologic data to design preclinical studies. We and others previously reported whole-exome sequencing data of 106 HNSCC primary tumors. In 2012, high-throughput genomic data and pharmacologic profiling of anticancer drugs of hundreds of cancer cell lines were reported. Here, we compared the genomic data of 39 HNSCC cell lines with the genomic findings in 106 HNSCC tumors...

Autism is a highly heritable neurodevelopmental disorder, and known genetic variants, mostly rare, account only for a small proportion of cases. Here we report a genome-wide association study on autism using two Chinese cohorts as gene discovery (n=2150) and three data sets of European ancestry populations for replication analysis of top association signals. Meta-analysis identified three single-nucleotide polymorphisms, rs936938 (P=4.49 × 10(-8)), non-synonymous rs6537835 (P=3.26 × 10(-8)) and rs1877455 (P=8...
