Abstract
Cancer stem cells (CSCs), as parts of tumor initiation cells, play a crucial role to tumorigenesis, development and recurrence. However, the complicated mechanisms of CSCs to adapt to tumor microenvironment and its stemness maintenance remains unclear. Here, we show that oxidized ATM, a hypoxia-activated cytoplasm ATM, acts a novel function to maintain CSC stemness in triple-negative breast cancer cells (BCSCs) via regulating histone H4 acetylation. Mechanistically, oxidized ATM phosphorylates TRIM21 (a E3 ubiquitin ligase) serine 80 and serine 469. Serine 80 phosphorylation of TRIM21 is essential for the ubiquitination activity of TRIM21. TRIM21 binds with SIRT1 (one of deacetylase), resulting in ubiquitylation-mediated degradation of SIRT1. The reduced SIRT1 leads to increase of histone H4 acetylation, thus facilitating CSC-related gene expression. Clinical data verify that high level of ATM in breast tumors is positively correlated with malignant grade, and is closely related with low SIRT1, high p-TRIM21, and high CD44 expression. In conclusion, our study provides a novel mechanism by which oxidized ATM governing BCSCs stemness and reveals an important link among oxidized ATM, histone acetylation, and BCSCs maintenance.

RBM3 suppresses stemness remodeling of prostate cancer in bone microenvironment by modulating N6-methyladenosine on CTNNB1 mRNA. Cell Death Dis 2023; 14:91. [PMID: 36750551 PMCID: PMC9905585 DOI: 10.1038/s41419-023-05627-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 01/23/2023] [Accepted: 01/26/2023] [Indexed: 02/09/2023]
Abstract
Bone metastasis is the most happened metastatic event in prostate cancer (PCa) and needs a large effort in treatment. When PCa metastasizes to the bone, the new microenvironment can induce the epigenome reprogramming and stemness remodeling of cancer cells, thereby increasing the adaptability of cancer cells to the bone microenvironment, and this even leads to the occurrence of secondary tumor metastasis. Our group has previously found that RNA binding motif 3 (RBM3) affects the stem cell-like properties of PCa by interfering with alternative splicing of CD44. However, whether RBM3, as a stress-response protein, can resist microenvironmental remodeling of PCa particularly in bone metastasis remains unknown. By co-culturing PCa cells with osteoblasts to mimic PCa bone metastases, we found that RBM3 upregulates the N6-methyladenosine (m6A) methylation on the mRNA of catenin beta 1 (CTNNB1) in a manner dependent on methyltransferase 3 (METTL3), an N6-adenosine-methyltransferase complex catalytic subunit. Consequently, this modification results in a decreased stability of CTNNB1 mRNA and a followed inactivation of Wnt signaling, which ultimately inhibits the stemness remodeling of PCa cells by osteoblasts. Thus, the present study may extend our understanding of the inhibitory role of RBM3 on particularly bone metastasis of PCa.

Metastatic tumor antigen 1 contributes to hepatocarcinogenesis posttranscriptionally through RNA-binding function. Hepatology 2023; 77:379-394.

Abstract
BACKGROUND AND AIMS Both nuclear and cytoplasmic overexpression of metastatic tumor antigen 1 (MTA1) contributes to tumorigenesis of HCC. Most studies have focused on nuclear MTA1 whose function is mainly a chromatin modifier regulating the expression of various cancer-promoting genes. By contrast, the molecular mechanisms of cytoplasmic MTA1 in carcinogenesis remain elusive. Here, we reveal a role of MTA1 in posttranscriptional gene regulation. APPROACH AND RESULTS We conducted the in vitro and in vivo RNA-protein interaction assays indicating that MTA1 could bind directly to the 3'-untranslated region of MYC RNA. Mutation at the first glycine of the conserved GXXG loop within a K-homology II domain-like structure in MTA1 (G78D) resulted in the loss of RNA-binding activity. We used gain- and loss-of-function strategy showing that MTA1, but not the G78D mutant, extended the half-life of MYC and protected it from the lethal -7-mediated degradation. The G78D mutant exhibited lower activity in promoting tumorigenesis than wild-type in vitro and in vivo. Furthermore, RNA-immunoprecipitation sequencing analysis demonstrated that MTA1 binds various oncogenesis-related mRNAs besides MYC . The clinical relevance of cytoplasmic MTA1 and its interaction with MYC were investigated using HBV-HCC cohorts with or without early recurrence. The results showed that higher cytoplasmic MTA1 level and MTA1- MYC interaction were associated with early recurrence. CONCLUSIONS MTA1 is a generic RNA-binding protein. Cytoplasmic MTA1 and its binding to MYC is associated with early recurrence in patients with HBV-HCC. This function enables it to regulate gene expression posttranscriptionally and contributes to hepatocarcinogenesis.

[PMID: 35944414 PMCID: PMC9365954 DOI: 10.1016/j.tranon.2022.101500] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2022] [Revised: 07/18/2022] [Accepted: 07/27/2022] [Indexed: 11/25/2022] Open
Abstract
MTA1 was highly expressed in NSCLC tissues and was associated with tumor progression. MTA1 promoted NSCLC cell invasion and migration in vitro and in vivo. TJP1 was found to be an interacting protein of MTA1 involved in cell adhesion. MTA1 promoted NSCLC invasion and metastasis by inhibiting TJP1 protein expression and attenuating intercellular tight junctions. Targeting the MTA1-TJP1 axis may be a promising strategy for inhibiting NSCLC metastasis.
Distant metastasis is the main cause of death in non-small cell lung cancer (NSCLC) patients. The mechanism of metastasis-associated protein 1(MTA1) in NSCLC has not been fully elucidated. This study aimed to reveal the mechanism of MTA1 in the invasion and metastasis of NSCLC. Bioinformatics analysis and our previous results showed that MTA1 was highly expressed in NSCLC tissues and correlated with tumor progression. Knockout of MTA1 by CRISPR/Cas9 significantly inhibited the migration and invasion of H1299 cells, but enhanced cell adhesion. Stable overexpression of MTA1 by lentivirus transfection had opposite effects on migration, invasion and adhesion of A549 cells. The results of in vivo experiments in nude mouse lung metastases model confirmed the promotion of MTA1 on invasion and migration. Tight junction protein 1 (TJP1) was identified by immunoprecipitation and mass spectrometry as an interacting protein of MTA1 involved in cell adhesion. MTA1 inhibited the expression level of TJP1 protein and weakened the tight junctions between cells. More importantly, the rescue assays confirmed that the regulation of MTA1 on cell adhesion, migration and invasion was partially attenuated by TJP1. In Conclusion, MTA1 inhibits the expression level of TJP1 protein co-localized in the cytoplasm and membrane of NSCLC cells, weakens the tight junctions between cells, and changes the adhesion, migration and invasion capabilities of cells, which may be the mechanism of MTA1 promoting the invasion and metastasis of NSCLC. Thus, targeting the MTA1-TJP1 axis may be a promising strategy for inhibiting NSCLC metastasis.

FTO downregulation mediated by hypoxia facilitates colorectal cancer metastasis. Oncogene 2021; 40:5168-5181.

Abstract
Fat mass and obesity-associated protein (FTO), an N6-methyladenosine (m6A) demethylase, participates in tumor progression and metastasis in many malignancies, but its role in colorectal cancer (CRC) is still unclear. Here, we found that FTO protein levels, but not RNA levels, were downregulated in CRC tissues. Reduced FTO protein expression was correlated with a high recurrence rate and poor prognosis in resectable CRC patients. Moreover, we demonstrated that hypoxia restrained FTO protein expression, mainly due to an increase in ubiquitin-mediated protein degradation. The serine/threonine kinase receptor associated protein (STRAP) might served as the E3 ligase and K216 was the major ubiquitination site responsible for hypoxia-induced FTO degradation. FTO inhibited CRC metastasis both in vitro and in vivo. Mechanistically, FTO exerted a tumor suppressive role by inhibiting metastasis-associated protein 1 (MTA1) expression in an m6A-dependent manner. Methylated MTA1 transcripts were recognized by an m6A "reader", insulin-like growth factor 2 mRNA binding protein 2 (IGF2BP2), which then stabilized its mRNA. Together, our findings highlight the critical role of FTO in CRC metastasis and reveal a novel epigenetic mechanism by which the hypoxic tumor microenvironment promotes CRC metastasis.

Abstract
BACKGROUND Chromatin modifier metastasis-associated protein 1 (MTA1), closely associated with tumor angiogenesis in breast cancer, plays an important role in gene expression and cancer cell behavior. Recently, an association between O-GlcNAc transferase (OGT) and MTA1 was identified by mass spectroscopy. However, the potential relationship between MTA1 and O-GlcNAc modification has not yet explored. METHODS In the current study, the role of MTA1 and its O-GlcNAc modification in breast cancer cell genotoxic adaptation was investigated through quantitative proteomics, chromatin immunoprecipitation followed by sequencing (ChIP-seq), transcriptome analysis, and loss- and gain-of-function experiments. RESULTS We demonstrate that the O-GlcNAc modification promotes MTA1 to interaction with chromatin and thus changes the expression of target genes, contributing to breast cancer cell genotoxic adaptation. MTA1 is modified with O-GlcNAc residues at serine (S) residues S237/S241/S246 in adriamycin-adaptive breast cancer cells, and this modification improves the genome-wide interactions of MTA1 with gene promotor regions by enhancing its association with nucleosome remodeling and histone deacetylation (NuRD) complex. Further, O-GlcNAc modification modulates MTA1 chromatin binding, influencing the specific transcriptional regulation of genes involved in the adaptation of breast cancer cells to genotoxic stress. CONCLUSIONS Our findings reveal a previously unrecognized role for O-GlcNAc-modified MTA1 in transcriptional regulation and suggest that the O-GlcNAc modification is a key to the molecular regulation of chemoresistance in breast cancers.

Abstract
Although NF-κB is known to play a pivotal role in lung cancer, contributing to tumor growth, microenvironmental changes, and metastasis, the epigenetic regulation of NF-κB in tumor context is largely unknown. Here we report that the IKK2/NF-κB signaling pathway modulates metastasis-associated protein 2 (MTA2), a component of the nucleosome remodeling and deacetylase complex (NuRD). In triple transgenic mice, downregulation of IKK2 (Sftpc-cRaf-IKK2DN) in cRaf-induced tumors in alveolar epithelial type II cells restricted tumor formation, whereas activation of IKK2 (Sftpc-cRaf-IKK2CA) supported tumor growth; both effects were accompanied by altered expression of MTA2. Further studies employing genetic inhibition of MTA2 suggested that in primary tumor growth, independent of IKK2, MTA2/NuRD corepressor complex negatively regulates NF-κB signaling and tumor growth, whereas later dissociation of MTA2/NuRD complex from the promoter of NF-κB target genes and IKK2-dependent positive regulation of MTA2 leads to activation of NF-κB signaling, epithelial-mesenchymal transition, and lung tumor metastasis. These findings reveal a previously unrecognized biphasic role of MTA2 in IKK2/NF-κB-driven primary-to-metastatic lung tumor progression. Addressing the interaction between MTA2 and NF-κB would provide potential targets for intervention of tumor growth and metastasis. SIGNIFICANCE: These findings strongly suggest a prominent role of MTA2 in primary tumor growth, lung metastasis, and NF-κB signaling modulatory functions.

Abstract
Glioblastomas (GBMs) are classified into isocitrate dehydrogenase (IDH) mutant (IDH MT) and wild-type (IDH WT) subtypes, and each is associated with distinct tumor behavior and prognosis. The present study aimed to investigate differentially expressed long non-coding (lnc)RNAs and mRNAs between IDH MT and IDH WT GBMs, as well as to explore the interaction and potential functions of these RNAs. A total of 132 GBM samples with RNA profiling data (10 IDH MT and 122 IDH WT cases) were obtained from The Cancer Genome Atlas, and 62/78 and 142/219 up/downregulated lncRNAs and mRNAs between IDH MT and IDH WT GBMs were identified, respectively. Multivariate Cox analysis of the dysregulated lncRNAs/mRNAs identified three-lncRNA and fifteen-mRNA signatures with independent prognostic value, indicating that these RNAs may serve roles in determining distinct tumor behaviors and prognosis of patients with IDH MT/WT GBMs. Functional analysis of the three lncRNAs revealed that they were primarily associated with cell stemness or differentiation. Pearson's correlation analysis revealed that the protective lncRNA AC068643.1 was significantly positively correlated with two key bone morphogenetic protein (BMP) signaling-associated mRNAs, Bone morphogenetic protein 2 (BMP2) and Myostatin (MSTN), from the 15 mRNAs. Further in vitro studies demonstrated that BMP2 and MSTN directly stimulated AC068643.1 expression. In conclusion, the present study identified a BMP signaling pathway-regulated lncRNA AC068643.1, which may contribute to the different tumor behaviors observed between IDH MT and IDH WT GBMs.

Metastasis-associated protein 1 (MTA1) regulates the catecholamine production homeostasis via transcriptional repression of aromatic l-amino acid decarboxylase (Aadc) in the interstitial cells of Cajal of mouse prostate. Biochem Biophys Res Commun 2020; 528:732-739.

Abstract
Based on the lately identified role for the interstitial cells of Cajal (ICCs) of mouse prostate in catecholamine production, as well as the well-established role for the master coregulator metastasis-associated protein 1 (MTA1) in inflammation, we probed into the functional link between aberrant MTA1 expression and pathogenesis of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) using both a MTA1-/- mouse model of experimental autoimmune prostatitis (EAP) and an in vitro chronic prostatitis model in cultured murine ICCs. EAP-induced MTA1 expression was enriched in ICCs of mouse prostate. EAP resulted in a higher increase in the pelvic pain response in MTA1-/- mice compared to WT mice. Consistently, the ICCs from MTA1-/- mice produced higher levels of catecholamines upon induction of in vitro chronic prostatitis. Mechanistically, MTA1 could directly suppress the transcription of Aadc, a rate-limiting enzyme during catecholamine synthesis, in a HDAC2-depdendent manner. Importantly, treatment with AADC inhibitor NSD-1015 significantly ameliorated EAP-elicited pain response and catecholamine overactivity in MTA1-/- mice. Taken together, our findings reveal an inherent regulatory role of the MTA1/AADC pathway in the maintenance of catecholamine production homeostasis in prostate ICCs, and also point to a potential use of HDAC inhibitors and/or AADC inhibitors to treat CP/CPPS.

J Cell Mol Med 2020; 24:5998-6007. [PMID: 32187849 PMCID: PMC7294111 DOI: 10.1111/jcmm.15062] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2019] [Revised: 01/05/2020] [Accepted: 01/21/2020] [Indexed: 02/06/2023] Open
Abstract
Idiopathic pulmonary fibrosis (IPF) is a progressive and usually fatal lung disease that lacking effective interventions. It is well known that aberrant activation of transforming growth factor‐beta1 (TGF‐β1) frequently promotes epithelial‐mesenchymal transition (EMT) in IPF. Metastasis‐associated gene 1 (MTA1) has identified as an oncogene in several human tumours, and aberrant MTA1 expression has been related to the EMT regulation. However, its expression and function in IPF remain largely unexplored. Using a combination of in vitro and in vivo studies, we found that MTA1 was significantly up‐regulated in bleomycin‐induced fibrosis rats and TGF‐β1‐treated alveolar type Ⅱ epithelial (RLE‐6TN) cells. Overexpression of MTA1 induced EMT of RLE‐6TN cells, as well as facilitates cell proliferation and migration. In contrast, knockdown of MTA1 reversed TGF‐β1‐induced EMT of RLE‐6TN cells. The pro‐fibrotic action of MTA1 was mediated by increasing Snail expression through up‐regulating Snail promoter activity. Moreover, inhibition of MTA1 effectively attenuated bleomycin‐induced fibrosis in rats. Additionally, we preliminarily found astragaloside IV (ASV), which was previously validated having inhibitory effects on TGF‐β1‐induced EMT, could inhibit MTA1 expression in TGF‐β1‐treated RLE‐6TN cells. These findings highlight the role of MTA1 in TGF‐β1‐mediated EMT that offer novel strategies for the prevention and treatment of IPF.

Down-regulation of SOX18 inhibits laryngeal carcinoma cell proliferation, migration, and invasion through JAK2/STAT3 signaling. Biosci Rep 2019; 39:BSR20182480.

Abstract
Laryngeal carcinoma is one of the most common malignant tumors of the head, neck, and respiratory tract. The aim of the present study is to explore the biological function of SRY-related HMG-box 18 (SOX18) in laryngeal carcinoma cells and study the molecular mechanism involved. Initial findings indicate that the expression of SOX18 was increased in laryngeal carcinoma cell lines and tissues. The effect of SOX18 on laryngeal carcinoma cell proliferation, cell cycle, apoptosis, invasion, and migration was also identified. The results indicated that down-regulation of SOX18 significantly inhibited cell proliferation, migration, and invasion, and induced cell-cycle arrest in G0/G1 phase and apoptosis of laryngeal carcinoma cells. However, overexpression of SOX18 promoted cell proliferation, invasion, and migration, and inhibited cell apoptosis. The expression of cyclin D1, active-caspase-3, N-cadherin, MTA1, MMP-2, and MMP-7 was also regulated by the overexpression of siSOX18 or SOX18. In addition, it was found that SOX18 could also accelerate the phosphorylation of JAK2/STAT3 signaling in laryngeal carcinoma cells. Furthermore, our study indicated that SOX18 could stimulate cell proliferation, migration, and invasion of laryngeal carcinoma cells via regulation of JAK2/STAT3 signaling, which could provide a new strategy for laryngeal carcinoma diagnosis and molecular therapies.

Abstract
OBJECTIVE Though metastasis-associated protein 1 (MTA1) is widely overexpressed in human cancers and is associated with advanced clinicopathological characteristics and survival in related diseases, the association between MTA1 and endometrial cancer (EC) is little known and needs to be studied. METHODS Western blot and immunohistochemistry were used to analyze protein expression level of cells and tissues, while real-time PCR was used for RNA detection. Bioinformatics tool analysis revealed the relationship between MTA1 and clinicopathological characteristics and survival. CCK-8 assay, colony-formation assay, cell scratch assay, and Transwell assay were performed to determine cell proliferation, migration and invasion abilities, respectively. RESULTS The expression level of MTA1 was significantly higher in human EC tissues than in normal endometrium. MTA1 expression was correlated positively with lymph nodes metastasis and poor survival rate in EC. Experimentally overexpressed MTA1 could promote cell proliferation, migration and invasion abilities of EC cell lines Ishikawa, HEC-1B, and RL-952, while reduction of MTA1 inhibited these cell biological behaviors. Moreover, MTA1 could also reverse the negative effect of miR-30c, a direct modulator of MTA1, on EC cells. Our research also revealed that overexpression of MTA1 contributed to EC tumor growth, while knockdown of MTA1 resulted in tumor growth inhibition. Additionally, the phosphorylation levels of mTOR (S2448) and 4E-BP1 (T37/46) changed significantly along with AKT (T308) under regulation of MTA1, both in vivo and vitro. CONCLUSION Our results showed that MTA1, as a downstream target of miR-30c, might promote EC progression via AKT/mTOR/4E-BP1 pathway, which indicated the potential therapy target of MTA1 in EC.

Abstract
Interleukin-17 (IL-17) has been shown to promote development of prostate, colon, skin, lung, breast, and pancreatic cancer. The purpose of this study was to determine if IL-17 regulates MTA1 expression and its biological consequences. Human cervical cancer HeLa and human prostate cancer DU-145 cell lines were used to test if IL-17 regulates metastasis associated 1 (MTA1) mRNA and protein expression using quantitative reverse transcription-polymerase chain reaction and Western blot analysis, respectively. Cell migration and invasion were studied using wound healing assays and invasion chamber assays. Thirty-four human cervical tissues were stained for IL-17 and MTA1 using immunohistochemical staining. We found that IL-17 increased MTA1 mRNA and protein expression in both cell lines. Cell migration was accelerated by IL-17, which was abolished by knockdown of MTA1 expression with small interference RNA (siRNA). Further, cell invasion was enhanced by IL-17, which was eliminated by MTA1 knockdown. Human cervical intra-epithelial neoplasia (CIN) and cervical cancer tissues had increased number of IL-17-positive cells and MTA1 expression compared to normal cervical tissues. The number of IL-17-positive cells was positively correlated with MTA1 expression. These findings demonstrate that IL-17 upregulates MTA1 mRNA and protein expression to promote HeLa and DU-145 cell migration and invasion.

Abstract
SPEN (spen family transcription repressor) is a nucleic acid-binding protein putatively involved in repression of gene expression. We hypothesized that SPEN could be involved in general downregulation of the transcription during the heat shock response in mouse spermatogenic cells through its interactions with chromatin. We documented predominant nuclear localization of the SPEN protein in spermatocytes and round spermatids, which was retained after heat shock. Moreover, the protein was excluded from the highly condensed chromatin. Chromatin immunoprecipitation experiments clearly indicated interactions of SPEN with chromatinin vivo. However, ChIP-Seq analyses did not reveal any strong specific peaks both in untreated and heat shocked cells, which might suggest dispersed localization of SPEN and/or its indirect binding to DNA. Usingin situproximity ligation assay we found closein vivoassociations of SPEN with MTA1 (metastasis-associated 1), a member of the nucleosome remodeling complex with histone deacetylase activity, which might contribute to interactions of SPEN with chromatin.

Abstract
The metastasis-associated gene 1 (MTA1) has previously been recognized as an oncogene, and abnormal MTA1 expression has been related to progression of numerous cancer types to the metastasis stage. However, the function of MTA1 in the regulation of pancreatic cancer progression and metastasis remains unclear. Western blot analysis was adopted to determine the expression of MTA1 in pancreatic cancer tissues and corresponding near normal tissues. Steady clone with MTA1-overexpression and MTA1-inhibitionweregenerated via lentivirus technology in BxPc-3 cells. Transwell assay was carried out for detecting the invasion of pancreatic cancer cells. The migration activity was assessed using the wound scratch assay. The effect of MTA1 in pancreatic cancer was evaluated in the mice xenografts. Western blot analysis was employed to determine the expression of hypoxia inducible factor-α (HIF-α) and vascular endothelial growth factor (VEGF) in vitro and in vivo. We observed that MTA1 overexpression enhanced migration and invasion ability of pancreatic cancer cells in vitro and increased HIF-α and VEGF protein levels in vitro and in vivo. MTA1 inhibition had the opposite effects. MTA1 protein level was positively related to HIF-α and VEGF protein levels. These results indicated that MTA1 potentially promoted pancreatic cancer metastasis via HIF-α/VEGF pathway. This research supplies a new molecular mechanism for MTA1 in the pancreatic cancer progression and metastasis. MTA1 may be an effective therapy target in pancreatic cancer.

Abstract
The cellular response to oxidative stress includes transcriptional changes, particularly for genes involved in DNA repair. Recently, our laboratory demonstrated that oxidation of 2'-deoxyguanosine (G) to 8-oxo-7,8-dihydro-2'-deoxyguanosine (OG) in G-rich potential G-quadruplex sequences (PQSs) in gene promoters impacts the level of gene expression up or down depending on the position of the PQS in the promoter. In the present report, bioinformatic analysis found that the 390 human DNA repair genes in the genome ontology initiative harbor 2936 PQSs in their promoters and 5'-untranslated regions (5'-UTRs). The average density of PQSs in human DNA repair genes was found to be nearly 2-fold greater than the average density of PQSs in all coding and noncoding human genes (7.5 vs 4.3 per gene). The distribution of the PQSs in the DNA repair genes on the nontranscribed (coding) vs transcribed strands reflects that of PQSs in all human genes. Next, literature data were interrogated to select 30 PQSs to catalog their ability to adopt G-quadruplex (G4) folds in vitro using five different experimental tests. The G4 characterization experiments concluded that 26 of the 30 sequences could adopt G4 topologies in solution. Last, four PQSs were synthesized into the promoter of a luciferase plasmid and cotransfected with the G4-specific ligands pyridostatin, Phen-DC3, or BRACO-19 in human cells to determine whether the PQSs could adopt G4 folds. The cell studies identified changes in luciferase expression when the G4 ligands were present, and the magnitude of the expression changes dependent on the PQS and the coding vs template strand on which the sequence resided. Our studies demonstrate PQSs exist at a high density in human DNA repair gene promoters and a subset of the identified sequences may fold in vitro and in vivo.

Abstract
Remarkably, majority of the cancer deaths are due to metastasis, not because of primary tumors. Metastasis is one of the important hallmarks of cancer. During metastasis invasion of primary tumor cells from the site of origin to a new organ occurs. Metastasis associated proteins (MTAs) are a small family of transcriptional coregulators that are closely associated with tumor metastasis. These proteins are integral components of nuclear remodeling and deacetylation complex (NuRD). By virtue of being integral components of NuRD, these proteins regulate the gene expression by altering the epigenetic changes such as acetylation and methylation on the target gene chromatin. Among the MTA proteins, MTA1 expression is very closely correlated with the aggressiveness of several cancers that includes breast, liver, colon, pancreas, prostate, blood, esophageal, gastro-intestinal etc. Considering its close association with aggressiveness in human cancers, MTA1 may be considered as a potential therapeutic target for cancer treatment. The recent developments in its crystal structure further strengthened the idea of developing small molecule inhibitors for MTA1. In this review, we discuss the recent trends on the diverse functions of MTA1 and its role in various cancers, with the focus to consider MTA1 as a 'druggable' target in the control of human cancers.

Abstract
Chromatin remodeling factor metastatic tumor protein 1 (MTA1), one of the most upregulated oncogene in human cancer, has an important role in gene expression, cell survival and promoting hypoxic response. Successful cancer progression is dependent on the ability of cells to utilize its survival pathways for adapting to hypoxic microenvironment. Although MTA1 is a stress-responsive gene, but whether hypoxia modulates its function and its role in engaging other core stress-responsive survival pathway(s) remains unknown. Here we have discovered that MTA1 is a novel corepressor of serum and glucocorticoid-inducible kinase 1 (SGK1). Surprisingly, this regulatory corepressive function of MTA1 is lost under hypoxia, allowing upregulation of SGK1 expression and engaging the MTA1-SGK1 axis for the benefit of the cell survival. The underlying mechanism of the noticed stimulation of SGK1 expression by hypoxia includes de-repression of SGK1 transcription because of hypoxia-triggered nucleus-to-cytoplasmic translocation of MTA1. In addition, the newly recognized cytoplasmic translocation of MTA1 was dependent on the chaperoning function of heat shock protein 90 (HSP90) and co-accompanied by the formation of MTA1, HSP90 and HIF1α complex under hypoxic condition but not under normoxic condition. Hypoxia-triggered redistribution of MTA1, SGK1 upregulation and cell survival functions were compromised by a pharmacological SGK1 inhibitor. In summary, for the first time, we report MTA1 regulation of SGK1 expression, hypoxia-dependent MTA1 translocation to the cytoplasm and de-repression of SGK1 transcription. These findings illustrate how cancer cells utilize a chromatin remodeling factor to engage a core survival pathway to support its cancerous phenotypes, and reveal new facets of MTA1-SGK1 axis by a physiologic signal in cancer progression.

Notch1 suppresses prostate cancer cell invasion via the metastasis-associated 1-KiSS-1 metastasis-suppressor pathway. Oncol Lett 2017; 14:4477-4482. [PMID: 29085444 PMCID: PMC5649609 DOI: 10.3892/ol.2017.6761] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2016] [Accepted: 02/14/2017] [Indexed: 01/28/2023] Open
Abstract
Notch1 is a type-1 transmembrane receptor which has been demonstrated to be involved in proliferation in various organisms. A number of studies have proposed that Notch signaling may be aberrantly activated, thus contributing to development, invasion and metastasis in a variety of human cancers. In the present study, the function and mechanism of Notch1 in human prostate cancer (PCa) LNCaP cells in vitro was investigated. Notch1 and cleaved-Notch1 expression were evaluated in human PCa cell lines, including LNCaP, PC-3 and DU 145, and the human prostate epithelial RWPE-1 cell line. LNCaP cells were transfected with Notch1-targeting short hairpin RNAs (shRNAs) and the level of proliferation, the ability to invade and the expression of genes associated with cancer cell invasion were subsequently investigated. Notch1 was highly expressed in LNCaP, PC-3 and DU 145 cells compared with RWPE-1 cells, while cleaved-Notch1 was expressed in LNCaP, PC-3 and DU 145 cells, and only to a minimal extent in RWPE-1 cells. Knockdown of Notch1 by shRNA in LNCaP cells markedly decreased cell invasion through Matrigel and inhibited cell proliferation 48 h following transfection. Reverse transcription-quantitative polymerase chain reaction analysis indicated that Notch1-knockdown resulted in a significant reduction of metastasis-associated 1 (MTA1) and increase of KiSS-1 metastasis-suppressor (KISS-1), mitogen-activated protein kinase 4 (MKK4) and cluster of differentiation 82 (KAI1). The present data demonstrated that expression of Notch1 was significantly associated with the invasion of prostate cancer. Knockdown of Notch1 decreased the invasive ability of LNCaP cells, which may be caused by downregulating MTA1 and upregulating KISS-1, MKK4 and KAI1. These findings indicated that targeting Notch1 may provide a novel method of suppressing or treating metastasis in prostate cancer.

Differential distribution of immune cells in breast invasive carcinoma vs. breast carcinoma in situ and its significance in interpretation of immune surveillance. INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL PATHOLOGY 2017; 10:7743-7749. [PMID: 31966621 PMCID: PMC6965287] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 04/12/2017] [Accepted: 06/23/2017] [Indexed: 06/10/2023]
Abstract
Immune surveillance is a highly controversial subject in both the field of immunology and cancer biology. On one hand, in spite of extensive studies, there is no cancer specific antigens identified. Yet, the organisms do exert immune response to tumors. On the other hand, it is believed that immune surveillance suppresses tumorigenesis by eradicating mutated cells. However, it is also widely known that tumorigenesis is promoted by inflammation, which is in nature immune reaction. In the present study, we tried to find immune cells in early tumor lesions for the supportive or negative evidence of immune surveillance. We used immunohistochemistry to observe the localization and distribution of immune cells in the in situ carcinoma lesions and in the invasive cancer of breast. Interestingly, we did not see immune cells in either ductal carcinoma in situ (DCIS) or lobular carcinoma in situ (LCIS) of breast, the two basic supposed early cancer forms. In contrast, we observed extensive infiltration of immune cells in the invasive breast cancer, and close contact between immune cells and tumor cells. Based on these findings, we propose that the tumor antigens of breast cancer are not derived from the gene mutation or amplification such as HER2, but rather from misplacement of epithelial cells in the mesenchymal tissue. To avoid being targeted by the immune system, the carcinoma cells exert epithelial-mesenchymal transition (EMT). Therefore, immunosurveillance could be regarded as preventing the intrusion of epithelial cells to mesenchymal tissues, and EMT is a form of immune escape by the strategy of mimicry.

Abstract
Epithelial-mesenchymal transition (EMT) is the phenotypic transition of epithelial cells to mesenchymal cells characterized by loss of epithelial markers, loss of intercellular adherence and acquirement of mesenchymal cell markers and increased locomotive ability. EMT is widely considered to be a gene regulated process necessary for cancer metastasis. Yet it is a highly controversial issue. We here propose that EMT is an environmentally induced cell behavior. It is the mimicry of their living environment. It is a survival strategy, a way of immune escape. We also propose here that the epithelial cell markers may functionally act as tumor antigens since in the mesenchymal surroundings there are no other structures bearing the same antigens as epithelial cells.

Virchows Arch 2016; 468:687-96.

Abstract
The prognostic value of androgen receptor (AR) and its related molecules in breast cancer is not well characterized. We retrospectively investigated 120 ER(+) and 120 ER(-) invasive breast cancers of 240 women, who were treated at our institution between January 2008 and December 2009. We excluded in situ, recurrent, metastatic, and bilateral carcinomas as well as non-epithelial lesions. Median follow-up was 74 months. Immunohistochemical assessment of expression of AR and metastasis-associated protein-1 (MTA1) resulted in 59.2 % (n = 142) AR(+) and 36.7 % (n = 88) high MTA1 expressing (MTA1(High)) carcinomas. MTA1(High) tumors were significantly more often ER(-), while AR(+) tumors were significantly more often HER2(+) (p < 0.01). MTA1(High)/ER(-) tumors were more often AR(-)/HER2(-) (p < 0.01). Patients with an AR(+)/ER(+) tumor had better disease-free survival (DFS; p = 0.011). Patients with an ER(-)/MTA1(High) tumor had significantly shorter DFS (p = 0.006) as well as patients with an AR(+)/HER2(+) tumor (p < 0.01). In Cox models, AR expression (HR, 0.248; 95 % CI, 0.086-0.716) and lymph node status (HR, 6.401; 95 % CI, 1.428-28.686) were independent predictors for DFS in ER(+) cancers, whereas AR(+)/HER2(+) expression status (HR, 2.927; 95 % CI, 1.256-6.821) and lymph node status (HR, 2.690; 95 % CI, 1.041-7.840) were independent predictors for DFS in ER(-) cancers. We show that AR might be an additional marker for endocrine responsiveness in ER(+) cancers and suggests that blocking MTA1 might be an effective way to inhibit AR/HER2 signaling in ER(-) breast cancer.

Abstract
The stress response gene activating transcription factor 4 (ATF4) is involved in metastatic behavior and cellular protection. Here we show that ATF4 is upregulated in osteosarcoma (OS) cell lines and patient clinical samples as compared to matched non-tumor tissue. Overexpression of ATF4 in OS cells promoted cell proliferation, migration and lung metastasis. Furthermore, the expression of ATF4 was markedly reduced in metastasis associated protein (MTA1) or histone deacetylase 1 (HDAC1) knockdown OS cells, but MTA1 overexpression increased the stability and activity of ATF4 protein via ATF4 deacetylation by HDAC1. ATF4 in turn enhanced the expression of MTA1 and HDAC1 at the transcription level, suggesting a positive feedback loop between ATF4 and MTA1/HDAC1. Clinically, the level of ATF4 was positively correlated with that of MTA1 in OS. Mice injected with ATF4-overexpressing cells exhibited a higher rate of tumor growth, and the average weight of these tumors was ~90% greater than the controls. Taken together, these data establish a direct correlation between ATF4-induced OS progression and MTA1/HDAC1-associated metastasis, and support the potential therapeutic value of targeting ATF4 in the treatment of OS.

Abstract
Since the initial recognition of the metastasis-associated protein 1 (MTA1) as a metastasis-relevant gene approximately 20 years ago, our appreciation for the complex role of the MTA family of coregulatory proteins in human cancer has profoundly grown. MTA proteins consist of six family members with similar structural units and act as central signaling nodes for integrating upstream signals into regulatory chromatin-remodeling networks, leading to regulation of gene expression in cancer cells. Substantial experimental and clinical evidence demonstrates that MTA proteins, particularly MTA1, are frequently deregulated in a wide range of human cancers. The MTA family governs cell survival, the invasive and metastatic phenotypes of cancer cells, and the aggressiveness of cancer and the prognosis of patients with MTA1 overexpressing cancers. Our discussion here highlights our current understanding of the regulatory mechanisms and functional roles of MTA proteins in cancer progression and expands upon the potential implications of MTA proteins in cancer biology and cancer therapeutics.
