Wu M, Jin MM, Cao XH, Zhao L, Li YH. Silencing TRIM29 Sensitizes Non-small Cell Lung Cancer Cells to Anlotinib by Promoting Apoptosis via Binding RAD50. Curr Cancer Drug Targets 2024; 24:445-454. [PMID: 37644752 DOI: 10.2174/1568009623666230829143148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Revised: 06/13/2023] [Accepted: 07/25/2023] [Indexed: 08/31/2023]
Abstract
BACKGROUND Previous studies have proposed that the transcriptional regulatory factor tripartite motif containing 29 (TRIM29) is involved in carcinogenesis via binding with nucleic acid. TRIM29 is confirmed to be highly expressed when the cancer cells acquire therapy-resistant properties. We noticed that TRIM29 levels were significantly increased in anlotinib-resistant NCIH1975 (NCI-H1975/AR) cells via mining data information from gene expression omnibus (GEO) gene microarray (GSE142031; log2 fold change > 1, p < 0.05). OBJECTIVE Our study aimed to investigate the function of TRIM29 on the resistance to anlotinib in non-small cell lung cancer (NSCLC) cells, including NCI-H1975 and A549 cells. METHODS Real-time RT-PCR and western blot were used to detect TRIM29 expression in anlotinib- resistant NSCLC (NSCLC/AR) cells. Apoptosis were determined through flow cytometry, acridine orange/ethidium bromide staining as well as western blot. ELISA was used to measure the content of C-X3-C motif chemokine ligand 1. Co-Immunoprecipitation assay was performed to verify the interaction between TRIM29 and RAD50 double-strand break repair protein (RAD50). RESULTS TRIM29 expression was shown to be elevated in the cytoplasm and nucleus of NSCLC/ AR cells compared to normal NSCLC cells. Next, we demonstrated that TRIM29 knockdown facilitated apoptosis and enhanced the sensitivity to anlotinib in NSCLC/AR cells. Based on the refined results citing from the database BioGRID, it was proved that TRIM29 interacted with RAD50. Herein, RAD50 overexpression diminished the pro-apoptotic effect induced by silencing TRIM29 in anlotinib-resistant A549 (A549/AR) cells. CONCLUSION Finally, we concluded that the increased sensitivity to anlotinib in NSCLC/AR cells was achieved by knocking down TRIM29, besides, the positive effects of TRIM29 knockdown were attributed to the promotion of apoptosis via binding to RAD50 in NSCLC/AR cell nucleus. Therefore, TRIM29 might become a potential target for overcoming anlotinib resistance in NSCLC treatment.

Yi Q, Zhao Y, Xia R, Wei Q, Chao F, Zhang R, Bian P, Lv L. TRIM29 hypermethylation drives esophageal cancer progression via suppression of ZNF750. Cell Death Discov 2023; 9:191. [PMID: 37365152 DOI: 10.1038/s41420-023-01491-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 06/06/2023] [Accepted: 06/15/2023] [Indexed: 06/28/2023] Open
Abstract
Esophageal cancer (ESCA) is the seventh most frequent and deadly neoplasm. Due to the lack of early diagnosis and high invasion/metastasis, the prognosis of ESCA remains very poor. Herein, we identify skin-related signatures as the most deficient signatures in invasive ESCA, which are regulated by the transcription factor ZNF750. Of note, we find that TRIM29 level strongly correlated with the expression of many genes in the skin-related signatures, including ZNF750. TRIM29 is significantly down-regulated due to hypermethylation of its promoter in both ESCA and precancerous lesions compared to normal tissues. Low TRIM29 expression and high methylation levels of its promoter are associated with malignant progression and poor clinical outcomes in ESCA patients. Functionally, TRIM29 overexpression markedly hinders proliferation, migration, invasion, and epithelial-mesenchymal transition of esophageal cancer cells, whereas opposing results are observed when TRIM29 is silenced in vitro. In addition, TRIM29 inhibits metastasis in vivo. Mechanistically, TRIM29 downregulation suppresses the expression of the tumor suppressor ZNF750 by activating the STAT3 signaling pathway. Overall, our study demonstrates that TRIM29 expression and its promoter methylation status could be potential early diagnostic and prognostic markers. It highlights the role of the TRIM29-ZNF750 signaling axis in modulating tumorigenesis and metastasis of esophageal cancer.

ANNALS OF TRANSLATIONAL MEDICINE 2021; 9:1537. [PMID: 34790743 PMCID: PMC8576676 DOI: 10.21037/atm-21-4679] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Accepted: 10/21/2021] [Indexed: 12/23/2022]
Abstract
Background This investigation examined the effects of the microRNA miR-34c-5p on the proliferation, migration, and invasion of oral squamous cell carcinoma (OSCC) and the mechanisms involved. Methods The Gene Expression Omnibus (GEO) database was used to filter the chips, and the GEO2R software (https://www.ncbi.nlm.nih.gov/geo/geo2r/) was used to analyze the microarray data (GSE28100 and GSE45238). Gene set enrichment analysis (GSEA) was used to study the relationship between the expression of miR-34c-5p and the distant metastasis and pathological grade of OSCC. The correlation between TRIM29 (tripartite motif containing 29) expression and the malignant clinical phenotype of OSCC was also examined. The mRNA and protein expression levels of miR-34c-5p and TRIM29 were measured by real time quantitative reverse transcription polymerase chain reaction (RT-qPCR) and Western blot analysis. The proliferation, migration, invasion and apoptosis of the human oral squamous carcinoma cell lines CAL-27 and Tca8113 was assessed by performing cell-counting kit-8 (CCK-8) assays, colony formation assays, transwell tests, wound scratch tests and flow cytometry. Luciferase reporter assays were used to predict the relationship between miR-34c-5p and TRIM29. A xenograft nude model was established and used to evaluate the effect of miR-34c-5p on tumor growth in female BALB/c mice. Results The expression of miR-34c-5p was significantly correlated with the proliferation, migration, and metastasis of OSCC. Overexpression of miR-34c-5p promoted the proliferation, migration, and invasion of CAL-27 and Tca8113 cells, and suppressed their apoptosis. Inversely, low expression of miR-34c-5p suppressed the proliferation, migration, and invasion of CAL-27 and Tca8113 cells, and promoted their apoptosis. Overexpression of miR-34c-5p promoted tumor growth in the xenograft nude mice model. The expression of TRIM29 was related to malignant clinical phenotype of OSCC. Overexpression of TRIM29 inhibited the proliferation, migration and invasion of CAL-27 and Tca8113 cell, and induced their apoptosis. TRIM29 knockout had just the opposite effect. Importantly, miR-34c-5p binds to TRIM29 and inhibited TRIM29 expression. Conclusions MiR-34c-5p regulates the proliferation, migration, invasion, and apoptosis of OSCC through targeted binding of TRIM29. This may represent a novel therapeutic target for the treatment of patients with OSCC.

Suppression of long noncoding RNA LINC00324 restricts cell proliferation and invasion of papillary thyroid carcinoma through downregulation of TRIM29 via upregulating microRNA-195-5p. Aging (Albany NY) 2020; 12:26000-26011. [PMID: 33318312 PMCID: PMC7803523 DOI: 10.18632/aging.202219] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Accepted: 10/23/2020] [Indexed: 12/13/2022]
Abstract
Long noncoding RNAs (lncRNAs) are identified as novel regulators of carcinogenesis. To date, the precise functions of lncRNAs in papillary thyroid carcinoma (PTC) remains poorly understood. The purposes of this work were to explore the potential relevance of lncRNA 00324 (LINC00324) in PTC. Levels of LINC00324 were markedly up-regulated in PTC. Silencing of LINC00324 significantly repressed the proliferation and invasion of PTC cells. LINC00324 was documented as a sponge of microRNA-195-5p (miR-195-5p). Decreased levels of miR-195-5p were detected in PTC. The up-regulation of miR-195-5p suppressed PTC cellular proliferation and invasion. Suppression of miR-195-5p partially reversed the LINC00324-knockdown-mediated effects in PTC cells. We identified tripartite motif-containing 29 (TRIM29) as a target gene of miR-195-5p. TRIM29 overexpression partially reversed the LINC00324-knockdown- or miR-195-5p-overexpression-mediated effects in PTC cells. In short, this work demonstrates that LINC00324 knockdown inhibits the proliferation and invasion of PTC cells by decreasing TRIM29 expression via up-regulating miR-195-5p expression.

Abstract
BACKGROUND C-Myc is one of the major cellular oncogenes overexpressed in non-small cell lung carcinoma (NSCLC). Its deregulated expression is necessary but not sufficient for malignant transformation. We evaluated expression of MYC gene in NSCLC patients and its association with alterations in the genes previously identified to be related to NSCLC pathogenesis, PHACTR3 and E2F4. METHODS We analyzed MYC gene expression by qRT-PCR in 30 NSCLC patients' samples and paired normal lung tissue. MYC expression was further statistically evaluated in relation to histopathological parameters, PHACTR3 and E2F4 gene alterations and survival. Alterations in aforementioned genes were previously detected and identified based on AP-PCR profiles of paired normal and tumor DNA samples, selection of DNA bands with altered mobility in tumor samples and their characterization by the reamplification, cloning and sequencing. RESULTS MYC expression was significantly increased in NSCLC samples and its overexpression significantly associated with squamous cell carcinoma subtype. Most importantly, MYC overexpression significantly coincided with mutations in PHACTR3 and E2F4 genes, in group of all patients and in squamous cell carcinoma subtype. Moreover, patients with jointly overexpressed MYC and altered PHACTR3 or E2F4 showed trend of shorter survival. CONCLUSIONS Overall, MYC is frequently overexpressed in NSCLC and it is associated with mutated PHACTR3 gene, as well as mutated E2F4 gene. These joint gene alterations could be considered as potential molecular markers of NSCLC and its specific subtypes.

Abstract
Background Tripartite Motif 29 (TRIM29) has been newly identified as being implicated in cancer progression. However, the biological role and molecular mechanism of TRIM29 in the invasion and metastasis of colorectal cancer (CRC) remain to be determined. Methods The expression levels of TRIM29 and β-catenin in CRC patient specimens were detected by immunohistochemistry. Recombinant lentivirus vectors containing the TRIM29 gene and its small hairpin interfering RNAs were constructed and transduced into CRC cells. Wound-healing and Transwell assays were performed to evaluate the migration and invasion abilities of CRC cells in vitro. Hepatic metastasis models in nude mice were established to validate the function of TRIM29 in vivo. Moreover, the expressions of epithelial-to-mesenchymal transition (EMT)-associated proteins were detected by qRT-PCR and Western blotting in CRC cells. Finally, Western blotting, qRT-PCR, luciferase reporter assays, and immunofluorescence assays were used to explore the molecular mechanisms of TRIM29 in CRC progression. Results Increased TRIM29 expression positively correlated with lymph node metastasis and β-catenin expression in patient CRC tissues. Overexpression of TRIM29 promoted invasion and metastasis of CRC cells in vitro and in vivo by regulating EMT, whereas the knockdown of TRIM29 had the opposite effect. Further mechanistic studies suggest that TRIM29 can activate the Wnt/β-catenin signaling pathway via up-regulating CD44 expression in colorectal cancer. Conclusions TRIM29 induces EMT through activating the Wnt/β-catenin signaling pathway via up-regulating CD44 expression, thus promoting invasion and metastasis of CRC.

Abstract
Basal subtype cancers are deadly malignancies but the molecular events driving tumor lethality are not completely understood. Ataxia-Telangiectasia Group D Complementing gene (ATDC, also known as TRIM29), is highly expressed and drives tumor formation and invasion in human bladder cancers but the factor(s) regulating its expression in bladder cancer are unknown. Molecular subtyping of bladder cancer has identified an aggressive basal subtype which shares molecular features of basal/squamous tumors arising in other organs and is defined by activation of a TP63-driven gene program. Here we demonstrate that ATDC is linked with expression of TP63 and highly expressed in basal bladder cancers. We find that TP63 binds to transcriptional regulatory regions of ATDC and KRT14 directly, increasing their expression, and that ATDC and KRT14 execute a TP63-driven invasive program. In vivo, ATDC is required for TP63-induced bladder tumor invasion and metastasis. These results link TP63 and the basal gene expression program to ATDC and to aggressive tumor behavior. Defining ATDC as a molecular determinant of aggressive, basal cancers may lead to improved biomarkers and therapeutic approaches.

Abstract
TRIM29 plays an important role in many neoplasms. In this study, we aimed to elucidate its role in hepatocellular carcinoma (HCC) and explore the corresponding potential mechanism. The expression level of TRIM29 in HCC samples and hepatoma cell lines was detected. We found that TRIM29 was down-regulated in clinical HCC samples and cultured hepatoma cell lines by western blot analysis and quantitative polymerase chain reaction. In addition, we demonstrated that higher TRIM29 expression was associated with higher differentiation grade of HCC. To explore the effect of TRIM29 on hepatoma cells and its possible mechanisms, TRIM29-knockdown and overexpression cell models were constructed. The results showed that the depletion of TRIM29 promoted liver cancer cell proliferation, clone formation, migration and invasion in vitro probably through the Wnt/β-catenin signaling pathway. This study revealed the inhibitory roles of TRIM29 in HCC and the possible mechanisms.

Abstract
: TRIM29 (tripartite motif-containing protein 29) is a TRIM family protein that has been implicated in breast, colorectal, and pancreatic cancers. However, its role in stratified squamous epithelial cells and tumors has not been elucidated. Here, we investigate the expression of TRIM29 in cutaneous head and neck squamous cell carcinomas (SCC) and its functions in the tumorigenesis of such cancers. TRIM29 expression was lower in malignant SCC lesions than in adjacent normal epithelial tissue or benign tumors. Lower expression of TRIM29 was associated with higher SCC invasiveness. Primary tumors of cutaneous SCC showed aberrant hypermethylation of TRIM29. Depletion of TRIM29 increased cancer cell migration and invasion; conversely, overexpression of TRIM29 suppressed these. Comprehensive proteomics and immunoprecipitation analyses identified keratins and keratin-interacting protein FAM83H as TRIM29 interactors. Knockdown of TRIM29 led to ectopic keratin localization of keratinocytes. In primary tumors, lower TRIM29 expression correlated with the altered expression of keratins. Our findings reveal an unexpected role for TRIM29 in regulating the distribution of keratins, as well as in the migration and invasion of SCC. They also suggest that the TRIM29-keratin axis could serve as a diagnostic and prognostic marker in stratified epithelial tumors and may provide a target for SCC therapeutics. SIGNIFICANCE: These findings identify TRIM29 as a novel diagnostic and prognostic marker in stratified epithelial tissues.

Abstract
To identify metastasis-related proteins in nasopharyngeal carcinoma (NPC), iTRAQ-tagging combined with 2D LC-MS/MS analysis was performed to identify the differentially expressed proteins (DEPs) in high metastatic NPC 5-8F cells and non-metastatic NPC 6-10B cells, and qRT-PCR and Western blotting were used to confirm DEPs. As a result, 101 DEPs were identified by proteomics, and 12 DEPs were selectively validated. We further detected expression of three DEPs (RAN, SQSTM1 and TRIM29) in a cohort of NPC tissue specimens to assess their value as NPC metastatic biomarkers, and found that combination of RAN, SQSTM1 and TRIM29 could discriminate metastatic NPC from non-metastatic NPC with a sensitivity of 88% and a specificity of 91%. TRIM29 and RAN expression level were closely correlated with lymph node and distant metastasis and clinical stage (P <0.05) in NPC patients. Finally, a combination of loss-of-function and gain-of-function approaches was performed to determine the effects of TRIM29 on NPC cell proliferation, migration, invasion and metastasis. The results showed that TRIM29 knockdown significantly attenuated while TRIM29 overexpression promoted NPC cell in vitro proliferation, migration and invasion and in vivo metastasis. The present data first time show that SQSTM1, RAN and TRIM29 are novel potential biomarkers for predicting NPC metastasis, demonstrate that TRIM29 is a metastasis-promoted protein of NPC.

Abstract
Noxin (also called chromosome 11 open reading frame 82 or DNA damage-induced apoptosis suppressor) is associated with anti-apoptosis and cell proliferation in response to stress signals. However, to our knowledge, the role of Noxin in regulating cell proliferation is still controversial and there are no reports of the function and clinicopathological association in breast cancer. In this study, immunohistochemistry results showed that Noxin expression was significantly correlated with advanced tumor-node-metastasis stage ( p = 0.027), positive regional lymph node metastasis ( p = 0.002), and poor overall survival ( p = 0.002). Proliferation assay results showed that Noxin obviously promoted the ability of proliferation of normal breast cells. Subsequent western blot results revealed that Cyclin D1 and Cyclin E1 were upregulated by overexpressing Noxin, whereas Cyclin D1 and Cyclin E1 were downregulated after depleting Noxin. The levels of phosphorylated P38 and activating transcription factor 2 were obviously increased after overexpressing Noxin, and their expression was downregulated accordingly by transfecting Noxin-small interfering RNA. Moreover, P38 inhibitor counteracted the elevating expression of phosphorylated activating transcription factor 2, Cyclin D1, and Cyclin E1 induced by Noxin overexpression and thereby reversed the effect of Noxin overexpression on facilitating cell growth. Taken together, our studies indicated that Noxin was overexpressed in breast cancer and its positive expression was significantly correlated with advance tumor-node-metastasis stage, positive lymph node metastasis, and poor prognosis. Noxin facilitated the expression of Cyclin D1 and Cyclin E1 through activating P38-activating transcription factor 2 signaling pathway, thus enhanced cell growth of breast cancer.

Abstract
Green tea, the fresh leaves of Camellia sinensis, is not only a health-promoting beverage but also a traditional Chinese medicine used for prevention or treatment of cancer, such as lung cancer. Theabrownin (TB) is the main fraction responsible for the medicinal effects of green tea, but whether it possesses anti-cancer effect is unknown yet. This study aimed to determine the in vitro and in vivo anti-lung cancer effect of TB and explore the underlying molecular mechanism, by using A549 cell line and Lewis lung carcinoma-bearing mice. In cellular experiment, MTT assay was performed to evaluate the inhibitory effect and IC50 values of TB, and flow cytometry was conducted to analyze the cell cycle progression affected by TB. In animal experiment, mice body mass, tumor incidence, tumor size and tumor weight were measured, and histopathological analysis on tumor was performed with Transferase dUTP nick-end labeling staining. Real time PCR and western blot assays were adopted to detect the expression of C-MYC associated genes and proteins for mechanism clarification. TB was found to inhibit A549 cell viability in a dose- and time-dependent manner and block A549 cell cycle at G0/G1 phase. Down-regulation of c-myc, cyclin A, cyclin D, cdk2, cdk4, proliferation of cell nuclear antigen and up-regulation of p21, p27, and phosphate and tension homolog in both gene and protein levels were observed with TB treatment. A c-myc-related mechanism was thereby proposed, since c-myc could transcriptionally regulate all other genes in its downstream region for G1/S transitions of cell cycle and proliferation of cancer cells. This is the first report regarding the anti-NSCLC effect and the underlying mechanism of TB on cell cycle progression and proliferation of A549 cells. The in vivo data verified the in vitro result that TB could significantly inhibit the lung cancer growth in mice and induce apoptosis on tumors in a dose-dependent manner. It provides a promising candidate of natural products for lung cancer therapy and new development of anti-cancer agent.

Abstract
Reduced ATM function has been linked to breast cancer risk, and the TRIM29 protein is an emerging breast cancer tumor suppressor. Here we show that, in cultured breast tumor and non-tumorigenic mammary epithelial cells, TRIM29 is up-regulated in response to hypoxic stress but not DNA damage. Hypoxia-induced up-regulation of TRIM29 is dependent upon ATM and HIF1α and occurs through increased transcription of the TRIM29 gene. Basal expression of TRIM29 is also down-regulated in cells expressing diminished levels of ATM, and findings suggest that this occurs through basal NF-κB activity as knockdown of the NF-κB subunit RelA suppresses TRIM29 abundance. We have previously shown that the activity of the TWIST1 oncogene is antagonized by TRIM29 and now show that TRIM29 is necessary to block the up-regulation of TWIST1 that occurs in response to hypoxic stress. This study establishes TRIM29 as a hypoxia-induced tumor suppressor gene and provides a novel molecular mechanism for ATM-dependent breast cancer suppression.

Abstract
Colorectal cancer (CRC) is one of the most common malignancies worldwide. Tripartite motif-containing 29 (TRIM29) is a member of TRIM proteins family, which plays diverse physiological and pathological roles in humans. Recent studies found that TRIM29 expressed highly in CRC and promoted cell growth in vitro. However, its function in the metastasis of CRC has not been studied. In the present study, we confirmed the previous report that TRIM29 was upregulated in CRC tissues and high levels of TRIM29 expression were associated with poor overall survival of patients. Moreover, TRIM29 knockdown significantly reduced cancer cell proliferation via notably inducing cell cycle arrest and cell apoptosis. Silencing of TRIM29 significantly inhibited the migration and invasion ability of CRC cells. The protein levels of apoptosis‑, migration‑ and invasion‑related proteins were also changed after TRIM29 knockdown. Furthermore, phosphorylation levels of JAK2 and STAT3 were clearly reduced in TRIM29 knockdown cells, indicating a possible mechanism underlying its effects on colorectal carcinogenesis. Collectively, TRIM29 may exert oncogenic effects in CRC cells via regulating JAK2/STAT3 signaling.

Abstract
Tripartite motif-containing 29 (TRIM29) has been reported to be dysregulated in human cancers. Up-regulation of TRIM29 was first observed in NPC cell lines by a genome-wide transcriptome analysis in our previous study. However, its expression biological function and clinical significance in nasopharyngeal carcinoma (NPC) remain unclear. In this study, TRIM29 expression was validated by qRT-PCR and immunohistochemistry in 69 NPC samples. Notably, TRIM29 protein expression was significantly and positively correlated with the tumor size, clinical stage and metastasis. TRIM29 was identified as the direct target of miR-335-5p and miR-15b-5p, both of which were down-regulated and negatively associated with TRIM29 expression in NPC cell lines and clinical samples. Ectopic TRIM29 expression promoted proliferation, epithelial-mesenchymal transition (EMT), migration and invasion in NPC cells, while its depletion inhibited cell invasion and EMT phenotype. Mechanistically, TRIM29 overexpression reduced PTEN expression and increase phosphorylated protein level of AKT, p70S6K and 4E-BP1. Correspondingly, AKT inhibitor and Rapamycin blocked the effect of TRIM29 on cell invasion. In conclusion, our results suggest that miR-335-5p and miR-15b-5p down-regulation results in TRIM29 over-expression, which induces proliferation, EMT and metastasis of NPC through the PTEN/AKT/mTOR signaling pathway.

Abstract
Purpose TRIM29 overexpression has been reported in several human malignancies and showed correlation with cancer cell malignancy. The aim of the current study is to examine its clinical significance and biological roles in human bladder cancer tissues and cell lines. Materials and Methods A total of 102 cases of bladder cancer tissues were examined for TRIM29 expression by immunohistochemistry. siRNA and plasmid transfection were performed in 5637 and BIU-87 cell lines. Cell Counting Kit-8, flow cytometry, western blot, and real-time polymerase chain reaction were performed to examine its biological roles and mechanism in bladder cancer cells. Results We found that TRIM29 overexpression showed correlation with invading depth (p=0.0087). Knockdown of TRIM29 expression in bladder cancer cell line 5637 inhibited cell growth rate and cell cycle transition while its overexpression in BIU-87 cells accelerated cell proliferation and cell cycle progression. TRIM29 overexpression also inhibited cell apoptosis induced by cisplatin. In addition, we demonstrated that TRIM29 depletion decreased while its overexpression led to upregulated expression of cyclin D1, cyclin E, and Bcl-2. We also showed that TRIM29 knockdown inhibited protein kinase C (PKC) and nuclear factor κB (NF-κB) signaling while its overexpression stimulated the PKC and NF-κB pathways. BAY 11-7082 (NF-κB inhibitor) partly attenuated the effect of TRIM29 on expression of cyclin and Bcl-2. Treatment with PKC inhibitor staurosporine resulted in ameliorated TRIM29 induced activation of NF-κB. Conclusion The current study demonstrated that TRIM29 upregulates cyclin and Bcl family proteins level to facilitate malignant cell growth and inhibit drug-induced apoptosis in bladder cancer, possibly through PKC–NF-κB signaling pathways.

Abstract
Induction of DNA damage by ionizing radiation (IR) and/or cytotoxic chemotherapy is an essential component of cancer therapy. The ataxia telangiectasia group D complementing gene (ATDC, also called TRIM29) is highly expressed in many malignancies. It participates in the DNA damage response downstream of ataxia telangiectasia-mutated (ATM) and p38/MK2 and promotes cell survival after IR. To elucidate the downstream mechanisms of ATDC-induced IR protection, we performed a mass spectrometry screen to identify ATDC binding partners. We identified a direct physical interaction between ATDC and the E3 ubiquitin ligase and DNA damage response protein, RNF8, which is required for ATDC-induced radioresistance. This interaction was refined to the C-terminal portion (amino acids 348-588) of ATDC and the RING domain of RNF8 and was disrupted by mutation of ATDC Ser-550 to alanine. Mutations disrupting this interaction abrogated ATDC-induced radioresistance. The interaction between RNF8 and ATDC, which was increased by IR, also promoted downstream DNA damage responses such as IR-induced γ-H2AX ubiquitination, 53BP1 phosphorylation, and subsequent resolution of the DNA damage foci. These studies define a novel function for ATDC in the RNF8-mediated DNA damage response and implicate RNF8 binding as a key determinant of the radioprotective function of ATDC.

Abstract
Background TRIM29 belongs to the tripartite motif (TRIM) protein family. It has been reported to be a tumor suppressor or have oncogenic function in many cancer types. The aim of this study was to investigate whether downregulation of TRIM29 by small interfering ribonucleic acid (siRNA) could inhibit cell proliferation and invasion and increase chemosensitivity to cisplatin in human lung squamous cancer NCI-H520 cells in vitro. Methods We transformed TRIM29 siRNA into NCI-H520 cells. Real time reverse transcriptase polymerase chain reaction and Western blotting assay were employed to determine TRIM29 messenger (m)RNA and protein expressions. MTT assay was used to determine the cell proliferation. Transwell invasion assay was used to determine the cell invasion. An Annexin V-propidium iodide (AnnV/PI) staining apoptosis test was used for detecting apoptosis. Results TRIM29 siRNA could specifically and efficiently suppress TRIM29 expression at both mRNA and protein levels. Silencing of the TRIM29 by siRNA in NCI-H520 cells inhibited cell proliferation and invasion in vitro. TRIM29 knockdown resulted in chemosensitivity enhancement in NCI-H520 cells. Conclusion Downregulation of TRIM29 can lead to potent antitumor activity and chemosensitizing effect in human lung squamous cancer NCI-H520 cells.

Abstract
TRIM29 (ATDC) exhibits a contextual function in cancer, but seems to exert a tumor-suppressor role in breast cancer. Here, we show that TRIM29 is often silenced in primary breast tumors and cultured tumor cells as a result of aberrant gene hypermethylation. RNAi-mediated silencing of TRIM29 in breast tumor cells increased their motility, invasiveness, and proliferation in a manner associated with increased expression of mesenchymal markers (N-cadherin and vimentin), decreased expression of epithelial markers (E-cadherin and EpCAM), and increased expression and activity of the oncogenic transcription factor TWIST1, an important driver of the epithelial-mesenchymal transition (EMT). Functional investigations revealed an inverse relationship in the expression of TRIM29 and TWIST1, suggesting the existence of a negative regulatory feedback loop. In support of this relationship, we found that TWIST1 inhibited TRIM29 promoter activity through direct binding to a region containing a cluster of consensus E-box elements, arguing that TWIST1 transcriptionally represses TRIM29 expression. Analysis of a public breast cancer gene-expression database indicated that reduced TRIM29 expression was associated with reduced relapse-free survival, increased tumor size, grade, and metastatic characteristics. Taken together, our results suggest that TRIM29 acts as a tumor suppressor in breast cancer through its ability to inhibit TWIST1 and suppress EMT.
