Abstract
HEY1-NCOA2 fusion is most described in mesenchymal chondrosarcoma. This is the first case report of a primary renal spindle cell neoplasm of uncertain malignant potential with a HEY1::NCOA2 fusion identified by Fusionplex RNA-sequencing that is histologically distinct from mesenchymal chondrosarcoma. The neoplasm was identified in a 33-year-old woman without significant past medical history who underwent partial nephrectomy for an incidentally discovered renal mass. The histologic features of the mass included spindle cells with variable cellularity and monotonous bland cytology forming vague fascicles and storiform architecture within a myxoedematous and collagenous stroma with areas of calcification. The morphologic and immunophenotypic features were not specific for any entity but were most similar to low-grade fibromyxoid sarcoma. To date, the patient has not had recurrence, and the malignant potential of the neoplasm is uncertain.

Abstract
Lung cancer is one of the most common malignancies and the leading cause of cancer-related death in the world. In patients with advanced lung adenocarcinoma who are negative for driver gene mutations, platinum-based chemotherapy represented by cisplatin remain the standard of care. Therefore, studying the mechanism behind inevitable cisplatin resistance in lung adenocarcinoma is still important. In this study, the potentially related differential expression gene for cisplatin resistance in lung adenocarcinoma was screened in the GEO database. The expression level of HEY1 in cell lines of lung adenocarcinoma was detected and HEY1 expression was up-regulated in cisplatin-resistant lung adenocarcinoma tissues and cell lines A549/DDP. Patients with high HEY1 expression have poor prognosis after cisplatin therapy. Gain and loss function assays uncovered that HEY1 could regulate the cisplatin sensitivity of NSCLC cells. In vivo experiments have confirmed that silence of HEY1 expression can induce cisplatin resistance, and epithelial-mesenchymal transition (EMT) changes occur during this process. Mechanically, HEY1 silencing significantly up-regulated E-cadherin expression and down-regulated Vimentin in A549/DDP cells. While up-regulation of HEY1 resulted in down-regulation of E-cadherin and up-regulation of Vimentin in A549 cells. Immunohistochemical experiments confirmed that E-cadherin was significantly decreased, and Vimentin expression was significantly up-regulated in cisplatin-resistant lung adenocarcinoma tissues. HEY1 can mediate the occurrence of cisplatin-acquired resistance in lung adenocarcinoma, and the possible mechanism is to regulate the EMT. The results of this study can provide a new direction and target for clinical research on the reversal of cisplatin resistance in lung adenocarcinoma.

Abstract
To investigate the function of hairy/enhancer-of-split related with YRPW motif protein 1 (HEY1) and Notch receptor 3 (NOTCH3) in ischemic stroke. Stroke models were established by middle cerebral artery occlusion (MCAO) and oxygen glucose deprivation (OGD) in rats and rat brain microvascular endothelial cells (BMVECs), respectively. Neurological deficit evaluation and 2,3,5-triphenyltetrazolium chloride staining were used to assess cerebral injury. The expression of HEY1 and NOTCH3 was manipulated using gain and loss of function approaches. Terminal deoxynucleotidyl transferase dUTP nick end labeling and Western blotting analysis of cleaved caspase-3 and B-cell lymphoma-2 (Bcl2) were used to evaluate apoptosis. Enzyme-linked immunosorbent assay was performed to measure the expression levels of interleukin (IL)-1β, IL-6 and IL-18. The proliferation and migration of BMVECs were analyzed by Ki-67 immunofluorescence and scratch assay, respectively. Tube formation assay was conducted to measure the length of capillary-like tubes formed by BMVECs. Co-immunoprecipitation was used to testify the relationship between HEY1 and NOTCH3. HEY1 and NOTCH3 were upregulated in MCAO and OGD models. HEY1 ameliorated ischemic injuries in MCAO rats. Knockdown of HEY1 or NOTCH3 promoted OGD-induced apoptosis and inflammation and inhibited proliferation and migration in BMVECs. NOTCH3 was a binding protein of HEY1. Overexpression of HEY1 offset the disease-promoting effect of NOTCH3 silencing. HEY1 suppresses apoptosis and inflammation and promotes proliferation and migration in BMVECs by upregulating NOTCH3, thereby ameliorating ischemic stroke.

Abstract
Upregulating the expression of long noncoding RNA LINC00982 controlled cell proliferation in gastric cancer, but the regulatory molecular mechanisms are yet to be expounded. We here aimed to elaborate how LINC00982 regulated the malignancy of gastric cancer cells. RT-qPCR and Western blot analysis were used to detect the expression of LINC00982 and cathepsin F (CTSF) in gastric cancer tissues and cells. Modulatory effect of LINC00982 on gastric cancer cells was assessed by CCK-8, colony formation, Transwell migration, and invasion assays. The relationship between LINC00982, YRPW motif 1 (HEY1), and CTSF was examined by RNA-binding protein immunoprecipitation, luciferase assay, and chromatin immunoprecipitation, and their interaction in the regulation of gastric cancer cellular functions was analyzed by performing gain-of-function and rescue assays. The nude mouse model of tumor formation was developed to examine the effects of LINC00982 on tumorigenesis. LINC00982 was lowly expressed in gastric cancer tissues, whereas its overexpression impaired the proliferative, migratory, and invasive properties of gastric cancer cells. Furthermore, LINC00982 could bind to transcription factor HEY1 and inhibited its expression. Through blocking the binding of HEY1 to CTSF promoter, LINC00982 promoted the expression of CTSF. Overexpression of HEY1 or inhibition of CTSF could reverse the antitumor effects of LINC00982 on gastric cancer, which were further demonstrated in vivo. All these taken together, LINC00982 acted as a tumor suppressor in gastric cancer, which is therefore suggested to be a potential antitumor target for gastric cancer.NEW & NOTEWORTHY We identified LINC00982 as a promising antitumor target for the treatment of patients with gastric cancer. We also determined a regulatory network involved in the pathophysiology of gastric cancer wherein LINC00982 could bind to HEY1 to impair its binding to cathepsin F (CTSF) promoter and hence promote CTSF expression, which aids in better understanding of molecular mechanisms related to gastric tumorigenesis.

Abstract
Several comprehensive studies have demonstrated that the NOTCH pathway is altered in a bimodal manner in head and neck squamous cell carcinoma (HNSCC). In a previous study, it was found that the NOTCH4/HEY1 pathway was specifically upregulated in HNSCC and promoted epithelial-mesenchymal transition (EMT), and that HEY1 activation supported SOX2 expression. However, the interactions in this pathway have not yet been fully elucidated. The present study investigated the NOTCH4/HEY1/SOX2 axis in HNSCC using in vitro models and the Cancer Genome Atlas (TCGA) database. To explore the association, reporter and ChIP RT-qPCR assays using SOX2-overexpressing (SOX2-OE) cells were performed. The association between NOTCH4 and HEY1 was examined in the same manner using HEY1-overexpressing (HEY1-OE) cells. The results of the in vitro experiments indicated that HEY1 promoted EMT in the HNSCC cells. Furthermore, the overexpression of HEY1 also promoted sphere formation and increased murine xenograft tumorigenicity. Reporter assays and ChIP RT-qPCR experiments indicated that SOX2 regulated HEY1 expression via direct binding of the HEY1 promoter. HEY1 expression significantly correlated with SOX2 expression in primary lung SCC and other SCCs using the TCGA database. HEY1 also regulated NOTCH4 expression to create a positive reciprocal feedback loop. On the whole, the present study demonstrates that HEY1 expression in HNSCC is regulated via the promotion of SOX2 and promotes EMT. The NOTCH4/HEY1 pathway is specifically upregulated via a positive reciprocal feedback loop mediated by the HEY1-medaited regulation of NOTCH4 transcription, and SOX2 correlates with HEY1 expression in SCC from other primary sites.

Abstract
Background Increasing evidence has uncovered the anticancer activity of lidocaine in many cancers. However, the role and the underlying molecular mechanism of lidocaine in colorectal cancer (CRC) remain poorly understood. Materials and Methods Cell viability and apoptosis were measured by cell counting kit-8 assay and flow cytometry. Western blot was used to detect the protein of p53, CyclinD1, Pro-caspase-3, Cleaved-caspase-3, Pro-caspase-9, Cleaved-caspase-9, and hes-related family bHLH transcription factor with YRPW motif 1 (HEY1). Glycolytic metabolism was calculated by measuring the glucose consumption, lactate production and adenosine triphosphate (ATP) contents. The expression of circRNA homer scaffold protein 1 (circHOMER1), microRNA (miR)-138-5p and HEY1 mRNA was detected by quantitative real-time polymerase chain reaction. The interaction between miR-138-5p and circHOMER1 or HEY1 was analyzed using the dual-luciferase reporter assay. In vivo experiments were performed using the murine xenograft model. Results Lidocaine suppressed CRC cell viability and aerobic glycolysis but promoted cell apoptosis in vitro as well as hindered tumor growth in vivo. CircHOMER1 was elevated in CRC tissues and cells, while lidocaine decreased circHOMER1 expression in CRC cells. Additionally, circHOMER1 overexpression reversed the anti-tumor activity of lidocaine in CRC cells. miR-138-5p was confirmed to interact with circHOMER1 and HEY1 in CRC cells directly, and circHOMER1 regulated HEY1 expression through repressing miR-138-5p expression. Besides, rescue assay indicated the anti-tumor activity mediated by lidocaine could be regulated by circHOMER1/miR-138-5p/HEY1 axis. Conclusion Lidocaine mediated CRC cell viability loss, apoptosis induction and aerobic glycolysis inhibition by regulating circHOMER1/miR-138-5p/HEY1 axis, providing a novel treatment option for lidocaine to prevent the progression of CRC.

Abstract
The homeobox transcription factor MEIS1 is involved in cell fate decision, stem cells properties, gastrointestinal (GI) tract development, and progression of several malignancies such as esophageal squamous cell carcinoma (ESCC). Increasing evidences suggest the crosstalk between MEIS1 and cell signaling pathways. Therefore, our aim in present study was to investigate the probable linkage of MEIS1 expression with key genes of different cell signaling pathways in ESCC tumorigenesis, and their correlation with clinicopathological feature of the patients. The gene expression profiling of MEIS1 and different cell signaling genes including SALL4, SIZN1, and HEY1 (stemness state, BMP, and NOTCH signaling pathways, respectively) was performed using quantitative real-time reverse transcription polymerase chain reaction (PCR) in fresh tumoral compared to margin normal tissues of 50 treatment-naive ESCC samples. The mRNA expression of MEIS1/SIZN1, SIZN1/HEY1, and SIZN1/SALL4 were significantly associated to each other (P < 0.05). There were remarkable correlations between concomitant mRNA expression of MEIS1 and SIZN1 in tumors with invasion to adventitia, early stages of tumor progression and poorly differentiated tumors. Moreover, expression of MEIS1 and HEY1 was correlated to each other in primary stages of tumor progression and non-invaded tumors. Expression of MEIS1 was significantly associated with SALL4 in poorly differentiated tumors. Our results indicated that correlation between different cell signaling pathway-related genes may lead to esophageal tumorigenesis. It is illustrated that MEIS1 as a HOX gene has a significant correlation with stemness state, BMP, and NOTCH signaling pathways via the SIZN1.

Abstract
Osteosarcoma is the most common primary malignant tumor of bone. Tumorigenic investigation of osteosarcoma cell lines may facilitate preclinical studies of targeted therapy. Therefore, the aim of this study was to explore the tumorigenicity-associated genes in osteosarcoma cells. We found that 138 genes were highly expressed and 86 genes were lowly expressed in highly tumorigenic osteosarcoma cell lines (143B, MNNG/HOS, and SJSA-1) compared with poorly tumorigenic osteosarcoma cell lines (MG-63, Saos-2, and U-2 OS). Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis revealed that highly expressed genes were associated with amino acids and energy metabolism, while lowly expressed genes were associated with cell cycle and DNA replication. Gene Ontology (GO) analysis showed that highly expressed genes were associated with endoplasmic reticulum stress response and aggrephagy, whereas lowly expressed genes were correlated with extracellular matrix assembly and DNA damage response. Further analysis identified six highly expressed genes and six lowly expressed genes. Three of highly expressed genes (DDX10, FOXA2, and HEY1) were correlated with poor prognosis, while three of lowly expressed genes (CYP26B1, GP1BB, and IFI44) showed the opposite trend in patients with osteosarcoma. Knockdown of HEY1 significantly inhibited the tumorigenicity of 143B cells in BALB/c nude mice.

Abstract
Our previous study demonstrated a close relationship between the NOTCH signaling pathway and salivary adenoid cystic carcinoma (SACC). Its receptor gene, NOTCH1, and its downstream gene, HES1, contribute to the proliferation, invasion and metastasis of SACC. Accumulating evidence supports HEY1 as another effector of the signaling pathway. The purpose of this study was to explore the effects of the NOTCH1-HEY1 pathway on the proliferation, invasion and metastasis of SACC cells. Our results verified that HEY1 is a specific molecular target of the NOTCH signaling pathway in SACC cells and that its expression in carcinoma is much higher than that in paracarcinoma tissues. The expression of NOTCH1 and HEY1 are positively correlated in the salivary adenoid cystic carcinoma tissues. NOTCH1 is significantly related to the activation of HEY1 in SACC, and that HEY1 reciprocally regulates NOTCH1 expression in SACC. HEY1 promotes cell proliferation and spheroid formation and inhibits cell apoptosis in vitro. In addition, HEY1 enhances the tumorigenicity of SACC in vivo. Furthermore, HEY1 increases cell invasion and metastasis by driving the expression of epithelial-mesenchymal transition (EMT)-related genes and MMPs. The results of this study indicate that the NOTCH1-HEY1 pathway is specifically upregulated in SACC and promotes cell proliferation, self-renewal, invasion, metastasis and the expression of EMT-related genes and MMPs. Our findings suggest that a NOTCH1-HEY1 pathway inhibitor might therefore have potential therapeutic applications in treating SACC patients by inhibiting cancer cell growth and metastasis.

Abstract
Background Breast cancer is one the most common cancers, making it the second leading cause of cancer-related death among women. Long non-coding RNAs (lncRNAs), with tightly regulated expression patterns, also serve as tumor suppressor during tumorigenesis. The present study aimed to elucidate the role of LINC00968 in breast cancer via WNT2-mediated Wnt2/β-catenin signaling pathway. Methods Breast cancer chip GSE26910 was utilized to identify differential expression in LINC00968 and WNT2. The possible relationship among LINC00968, transcriptional repressor HEY and WNT2 was analyzed and then verified. Effects of LINC00968 on activation of the Wnt2/β-catenin signaling pathway was also tested. Drug resistance, colony formation, cell migration, invasion ability and cell apoptosis after transfection were also determined. Furthermore, tumor xenograft in nude mice was performed to test tumor growth and weight in vivo. Results WNT2 expression exhibited at a high level, whereas LINC00968 at a low expression in breast cancer which was also associated with poor prognosis in patients. LINC00968 targeted and negatively regulated WNT2 potentially via HEY1. Either overexpressed LINC00968 or silenced inhibited activation of the Wnt2/β-catenin signaling pathway, thereby reducing drug resistance, decreasing colony formation ability, as well as suppressing migration and invasion abilities of breast cancer cells in addition to inducing apoptosis. Lastly, in vivo experiment suggested that LINC00968 overexpression also suppressed transplanted tumor growth in nude mice. Conclusion Collectively, overexpressed LINC00968 contributes to reduced drug resistance in breast cancer cells by inhibiting the activation of the Wnt2/β-catenin signaling pathway through silencing WNT2. This study offers a new target for the development of breast cancer treatment.

Abstract
OBJECTIVES Notch signaling is frequently altered in head and neck squamous cell carcinoma (HNSCC). However, the nature and clinical implications of this dysregulation are not well understood. We previously described an association of transcriptionally active NOTCH1 Intracellular Domain (NICD1) immunohistochemical (IHC) expression pattern with high-risk pathologic characteristics. Here we further characterize Notch signaling in HNSCC. MATERIALS AND METHODS IHC expression patterns and clinicopathologic associations of Notch pathway molecules were evaluated among 78 tumors with known NOTCH1 mutation status. IHC was performed for JAG1, a NOTCH1 activating ligand, and HEY1, an NICD1 transcriptional target and Notch pathway activation marker. IHC pattern and H-score (% staining × intensity) were recorded and compared to clinicopathologic characteristics and survival. Survival was analyzed using Kaplan Meier method and Cox proportional hazards models (HR). RESULTS JAG1 and NICD1 expression patterns were highly concordant among tumors without truncating NOTCH1 mutations (p < 0.001), but were dissimilar among tumors with truncating NOTCH1 mutations (p = 0.24). There was evidence for JAG1-independent NOTCH1 activation among seven tumors, all with wild-type NOTCH1. HEY1 expression was associated with neither JAG1 nor NICD1 expression, but was associated with NOTCH1 mutation status (p = 0.03). Twelve (16%) tumors expressed HEY1 but not NICD1. Higher HEY1 H-score was significantly associated with worse overall (adjusted hazard ratio [aHR] 2.0, 95% CI = 1.0-4.2) and disease-specific (aHR = 3.3, 95% CI = 1.4-7.9) survival, whereas JAG1 and NICD1 expression were not associated with survival. CONCLUSIONS These findings suggest both NOTCH1-dependent and -independent HEY1 regulation, and imply a previously unrecognized prognostic role for HEY1 in HNSCC.

Abstract
Mesenchymal chondrosarcoma is a rare but deadly form of chondrosarcoma that typically affects adolescents and young adults. While curative intent is possible for patients with localized disease, few options exist for patients in the unresectable/metastatic setting. Thus, it is imperative to understand the fusion-driven biology of this rare malignant neoplasm so as to lead to the future development of better therapeutics for this disease. This manuscript will briefly review the clinical and pathologic features of mesenchymal chondrosarcoma followed by an appraisal of existing data linked to the fusions, HEY1-NCOA2 and IRF2BP2-CDX1, and the associated downstream pathways.

Abstract
Hepatocellular carcinoma (HCC) was one of the most common cancers around the world, has very low 5-year survival rate. However, the mechanism of HCC occurrence and development is largely unknown. LDB2 belongs to the LIM-domain binding family and functions as an adaptor for transcriptional regulation. Here we found that LDB2 is downregulated in HCC samples. LDB2 has the ability to inhibit proliferation and migration of hepatocarcinoma cells. We found that the proliferation and migration abilities in HCC sample cells were impaired after LDB2 overexpression and vice versa. In mechanism, we found that LDB2 can recruit BRD7 to HEY1 promoter and then block its expression. HEY1 whose expression is upregulated in HCC acts as an oncogene. In brief, our research reveals a new regulatory mechanism for hepatocarcinoma cell proliferation and migration.

Abstract
HEY1-dependent activation of the p53 tumour suppressor pathway can be inhibited through direct phosphorylation of HEY1 at Ser-68 located in the bHLH domain. STK38 and STK38L serine/threonine kinases can phosphorylate HEY1 Ser-68 and could modulate its biological function. HEY1 (hairy/enhancer-of-split related with YRPW motif 1) is a member of the basic helix–loop–helix-orange (bHLH-O) family of transcription repressors that mediate Notch signalling. HEY1 acts as a positive regulator of the tumour suppressor p53 via still unknown mechanisms. A MALDI-TOF/TOF MS analysis has uncovered a novel HEY1 regulatory phosphorylation event at Ser-68. Strikingly, this single phosphorylation event controls HEY1 stability and function: simulation of HEY1 Ser-68 phosphorylation increases HEY1 protein stability but inhibits its ability to enhance p53 transcriptional activity. Unlike wild-type HEY1, expression of the phosphomimetic mutant HEY1-S68D failed to induce p53-dependent cell cycle arrest and it did not sensitize U2OS cells to p53-activating chemotherapeutic drugs. We have identified two related kinases, STK38 (serine/threonine kinase 38) and STK38L (serine/threonine kinase 38 like), which interact with and phosphorylate HEY1 at Ser-68. HEY1 is phosphorylated at Ser-68 during mitosis and it accumulates in the centrosomes of mitotic cells, suggesting a possible integration of HEY1-dependent signalling in centrosome function. Moreover, HEY1 interacts with a subset of p53-activating ribosomal proteins. Ribosomal stress causes HEY1 relocalization from the nucleoplasm to perinucleolar structures termed nucleolar caps. HEY1 interacts physically with at least one of the ribosomal proteins, RPL11, and both proteins cooperate in the inhibition of MDM2-mediated p53 degradation resulting in a synergistic positive effect on p53 transcriptional activity. HEY1 itself also interacts directly with MDM2 and it is subjected to MDM2-mediated degradation. Simulation of HEY1 Ser-68 phosphorylation prevents its interaction with p53, RPL11 and MDM2 and abolishes HEY1 migration to nucleolar caps upon ribosomal stress. Our findings uncover a novel mechanism for cross-talk between Notch signalling and nucleolar stress.

Abstract
Like normal stem cells, tumor-initiating cells (T-ICs) are regulated extrinsically within the tumor microenvironment. Because HCC develops primarily in the context of cirrhosis, in which there is an enrichment of activated fibroblasts, we hypothesized that cancer-associated fibroblasts (CAFs) would regulate liver T-ICs. We found that the presence of α-SMA(+) CAFs correlates with poor clinical outcome. CAF-derived HGF regulates liver T-ICs via activation of FRA1 in an Erk1,2-dependent manner. Further functional analysis identifies HEY1 as a direct downstream effector of FRA1. Using the STAM NASH-HCC mouse model, we find that HGF-induced FRA1 activation is associated with the fibrosis-dependent development of HCC. Thus, targeting the CAF-derived, HGF-mediated c-Met/FRA1/HEY1 cascade may be a therapeutic strategy for the treatment of HCC.
