We have previously shown that dysbindin is a potent inducer of cardiomyocyte hypertrophy via activation of Rho-dependent serum-response factor (SRF) signaling. We have now performed a yeast two-hybrid screen using dysbindin as bait against a cardiac cDNA library to identify the cardiac dysbindin interactome. Among several putative binding proteins, we identified tripartite motif-containing protein 24 (TRIM24) and confirmed this interaction by co-immunoprecipitation and co-immunostaining. Another tripartite motif (TRIM) family protein, TRIM32, has been reported earlier as an E3 ubiquitin ligase for dysbindin in skeletal muscle...

Tripartite motif-containing 24 (TRIM24) is important in tumor development and progression. However, the role of TRIM24 in gastric cancer (GC) and the mechanisms underlying the dysregulated expression of TRIM24 remain to be fully elucidated. In the present study, it was found that TRIM24 was frequently overexpressed in GC cell lines and tissues compared with normal controls, as determined by western blotting and immunohistochemical staining. The high nuclear expression of TRIM24 was correlated with the depth of invasion (P=0...

The Ovum Pick Up-In vitro Production (OPU-IVP) of embryos is an advanced reproductive technology used in cattle production but the complex biological mechanisms behind IVP outcomes are not fully understood. In this study we sequenced RNA of granulosa cells collected from Holstein cows at oocyte aspiration prior to IVP, to identify candidate genes and biological mechanisms for favourable IVP-related traits in donor cows where IVP was performed separately for each animal. We identified 56 genes significantly associated with IVP scores (BL rate, kinetic and morphology)...

Familial Papillary Thyroid Carcinoma (PTC) has been described as a hereditary predisposition cancer syndrome associated with mutations in candidate genes including HABP2. Two of 20 probands from families with history of PTC and breast carcinoma (BC) were evaluated by whole exome sequencing (WES) revealing HABP2 p.G534E. Sanger sequencing was used to confirm the involvement of this variant in three families (F1: 7 relatives; F2: 3 and F3: 3). The proband and his sister (with no malignant tumor so far) from F1 were homozygous for the variant whereas one relative with PTC from F2 was negative for the variant...

TRIM24, originally known as intermediary factor 1-alpha, is involved in the development of several cancers. This study aimed to evaluate the expression level and prognostic value of TRIM24 in cervical cancer. In the present study, we showed that the expression of TRIM24 was markedly upregulated in cervical cancer cell lines and cancerous specimens at both transcriptional and translational levels. TRIM24 expression was analyzed in 147 archived cervical cancer specimens using immunohistochemistry, and the correlation between TRIM24 expression and clinicopathological parameters was evaluated...

Tripartite motif-containing protein 24 (TRIM24) is closely correlated with multiple cancers, and a recent study demonstrated that the bromodomain of TRIM24 is essential for the proliferation of lethal castration-resistant prostate cancer. Here, we identify three new inhibitors of the TRIM24 bromodomain using NMR fragment-based screening. The crystal structures of two new inhibitors in complex with the TRIM24 bromodomain reveal that the water-bridged interaction network is conserved in the same fashion as those for known benzoimidazolone inhibitors...

BACKGROUND: Increasing evidence highlights the important roles of tripartite motif containing 24 (TRIM24) in tumor initiation and malignant progression in many tumors, including gastric cancer (GC). Although TRIM24 expression is remarkably upregulated during GC carcinogenesis, the molecular mechanisms underlying TRIM24 dysregulation remain unexplored. METHODS: In this study, miRNA target prediction tools were applied to explore miRNAs that potentially target TRIM24...

Sendai virus is an enveloped non-segmented negative-strand RNA virus that belongs to the genus Respirovirus of the Paramyxoviridae family. As a model pathogen, SeV has been extensively studied to define the basic biochemical and molecular biologic properties of the paramyxoviruses. In addition, SeV-infected host cells were widely employed to uncover the mechanism of innate immune response. To identify proteins involved in the SeV infection process or the SeV-induced innate immune response process, system-wide evaluations of SeV-host interactions have been performed...

BACKGROUND: Head and neck squamous cell carcinoma (HNSCC) represents a unique and major health concern worldwide. Significant increases in glucose uptake and aerobic glycolysis have been observed in HNSCC cells. Glucose transporters (GLUTs) represent a major hub in the glycolysis pathway, with GLUT4 having the highest glucose affinity. However, GLUT4's role in HNSCC has not been fully appreciated. METHODS: An in silico analysis was performed in HNSCC cohorts to identify the most significant glucose transporter associated with HNSCC patient prognosis...

Over the last few years, in vitro models, based on patient-derived induced pluripotent stem cells (iPSCs), have received considerable attention for modeling different neurodegenerative disorders. Using this model, we analyzed transcription of 15 tripartite motif (trim) genes in iPSCs, derived from the different groups: Parkinson's disease (PD) patients bearing mutations in different genes, patient with the sporadic form of PD, and the healthy individuals. The transcription was observed during neuronal differentiation of the cells in vitro into neuronal stem cells and terminally differentiated neurons...

Maintenance of pluripotency is regulated by a network of transcription factors coordinated by Oct4, Sox2, and Nanog (OSN), yet a systematic investigation of the composition and dynamics of the OSN protein network specifically on chromatin is still missing. Here we have developed a method combining ChIP with selective isolation of chromatin-associated proteins (SICAP) followed by mass spectrometry to identify chromatin-bound partners of a protein of interest. ChIP-SICAP in mouse embryonic stem cells (ESCs) identified over 400 proteins associating with OSN, including several whose interaction depends on the pluripotent state...

The entry of small molecule inhibitors of the bromodomain and extra C-terminal domain (BET) family of bromodomains into the clinic has demonstrated the therapeutic potential for this class of epigenetic acetyl-lysine reader proteins. Within the past two years, the development of potent inhibitors for the bromodomain and PHD finger containing protein (BRPF) family and the tripartite motif containing protein 24 (TRIM24) have been reported and are the subject of this review. Both proteins contain other domains with diverse functions and can also be part of a complex of proteins which have implications in epigenetic signaling and disease...

Srikanth Appikonda, Kaushik N Thakkar, Michelle Craig Barton
Tripartite Motif-containing protein 24 (TRIM24) functions as an E3 ligase targeting p53 for ubiquitination, a histone 'reader' that interacts with a specific signature of histone post-translational modifications and a co-regulator of nuclear receptor-regulated transcription. Although mouse models of Trim24 depletion suggest that TRIM24 may be a liver-specific tumor suppressor, several studies show that human TRIM24 is an oncogene when aberrantly over expressed. This review focuses on the mechanisms of TRIM24 functions in oncogenesis and metabolic reprogramming, which underlie recent interest in therapeutic targeting of aberrant TRIM24 in human cancers...

Tripartite motif-containing 24 (TRIM24), a member of the transcription intermediary factor 1 family, is defined as a co-regulator with several nuclear receptors, such as RARα. TRIM24 has been reported to be involved in many cancers. In this study, we aimed to investigate the expression pattern and prognostic significance of TRIM24 and its relationship with RARα in esophageal squamous cell cancer (ESCC). Both mRNA and protein expression levels of TRIM24 were found to be significantly decreased in ESCC, as judged by qRT-PCR and western blot...

BACKGROUND: Genetically induced hepatocellular carcinoma (HCC) models are generally used to investigate carcinogenesis pathways, but very few attempts were made to valorize them for pharmacological testing. This study describes a micro-computed tomography (micro-CT) - based methodology for the diagnostic and lifelong follow-up of HCC in the hepatocyte-specific Trim24-null mouse line. Myo-inositol trispyrophosphate (ITPP) was tested as anti-cancer drug. METHODS: Partial hepatectomy was performed in 2 months-old Trim24-null mice, in order to accelerate the carcinogenesis process...

Acetylated H3 lysine 23 (H3K23ac) is a specific histone post-translational modification recognized by oncoprotein TRIM24. However, it is not clear whether H3K23ac levels are correlated with TRIM24 expression and what role H3K23ac may have in cancer. In this study, we collected breast carcinoma samples from 121 patients and conducted immunohistochemistry to determine the levels of TRIM24 and H3K23ac in breast cancer. Our results demonstrated that TRIM24 expression is positively correlated with H3K23ac levels, and high levels of both TRIM24 and H3K23ac predict shorter overall survival of breast cancer patients...

COMMENT
Lalit R Patel, Michelle C Barton
Prostate cancer is lethal when tumors evolve to activate androgen receptor signaling, which circumvents ligand-deprivation therapy. In this issue of Cancer Cell, Groner et al. show that histone reader and transcription co-regulator TRIM24 occupies a central role in this evolution, nominating inhibitors of TRIM24's bromodomain as a new therapeutic avenue.
