Abstract
Transcriptional factor HOXB9, a part of the HOX gene family, plays a crucial role in the development of diverse cancer types. This study aimed to elucidate the regulatory mechanism of HOXB9 on the proliferation and invasion of laryngeal squamous cell carcinoma (LSCC) cells to provide guidance for the development and prognosis of LSCC. The CRISPR/Cas9 method was employed in LSCC cell lines to knock out the HOXB9 gene and validate its effects on the proliferation, migration, invasion, and regulation of LSCC cells. CCK-8 and flow cytometry were used to detect cell viability and proliferation; Tunnel was used to detect cell apoptosis, and transwell was used to detect cell migration and invasion. The effect of HOXB9 on tumor growth was tested in nude mice. The downstream target genes regulated by HOXB9 were screened by microarray analysis and verified by Western blotting, immunohistochemistry, chromatin immunoprecipitation, and double-luciferase reporter assays. The current research investigated molecular pathways governed by HOXB9 in the development of LSCC. Additionally, both laboratory- and living-organism-based investigations revealed that disrupting the HOXB9 gene through the CRISPR/CAS9 mechanism restrained cellular growth, movement, and infiltration, while enhancing cellular apoptosis. Detailed analyses of LSCC cell strains and human LSCC samples revealed that HOXB9 promoted LSCC progression by directly elevating the transcriptional activity of MMP12. HOXB9 could influence changes in LSCC cell functions, and the mechanism of action might be exerted through its downstream target gene, MMP12.

Discov Oncol 2023; 14:175.

Abstract
Human Hox genes (Homeobox) play a crucial role in embryonic development and cancer. The HOXC10 gene, a member of the HOX family, has been reported abnormally expressed in several cancers. However, the association between HOXC10 and hepatocellular carcinoma (HCC) remains to be elucidated. In the present study, tissue microarray cohort data showed that high levels of HOXC10 expression predicted a poor survival in HCC patients. Meanwhile, HOXC10 was significantly upregulated in the Huh7 cell line compared with the well differentiated cell line HepG2 and human normal liver cells. Functionally, silencing HOXC10 in Huh7 cells inhibited cell proliferation, increased apoptosis, and inhibited invasion and migration of HCC cells. HOXC10 overexpression in HepG2 cells increased cell proliferation, decreased apoptosis, and increased invasion and migration of HCC cells. In the HepG2 xenograft models, HOXC10 increased the tumor volume and weight compared with control. Mechanistically, the m6A modification of HOXC10 by METTL3 enhanced its expression by enhancing its mRNA stability. Both the in vitro and in vivo results showed that overexpressed HOXC10 activated the PTEN/AKT/mTOR pathway. In summary, the findings highlight the importance of HOXC10 in the regulation of HCC progression. HOXC10 is potentially a future therapeutic target for HCC treatment.

Potential target identification for osteosarcoma treatment: Gene expression re-analysis and drug repurposing. Gene X 2023; 856:147106. [PMID: 36513192 DOI: 10.1016/j.gene.2022.147106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Revised: 11/18/2022] [Accepted: 12/06/2022] [Indexed: 12/14/2022] Open
Abstract
Survival rate of osteosarcoma has remained plateaued for the past three decades. New treatment is needed to improve survival rate. Drug repurposing, a method to identify new indications of previous drugs, which saves time and cost compared to the de novo drug discovery. Data mining from gene expression profile was carried out and new potential targets were identified by using drug repurposing strategy. Selected data were newly categorized as pathophysiology and metastasis groups. Data were normalized and calculated the differential gene expression. Genes with log fold change ≥ 2 and adjusted p-value ≤ 0.05 were selected as primary candidate genes (PCGs). PCGs were further enriched to determine the secondary candidate genes (SCGs) by protein interaction analysis, upstream transcription factor and related-protein kinase identification. PCGs and SCGs were further matched with gene targeted of corresponding drugs from the Drug Repurposing Hub. A total of 778 targets were identified (360 from PCGs, and 418 from SCGs). This newly identified KLHL13 is a new candidate target based on its molecular function. KLHL13 was upregulated in clinical samples. We found 256 drugs from matching processes (50anti-cancerand206non-anticancerdrugs). Clinical trials of anti-cancer drugs from 5 targets (CDK4, BCL-2, JUN, SRC, PIK3CA) are being performed for osteosarcoma treatment. Niclosamide and synthetic PPARɣ ligands are candidates for repurposing due to the possibility based on their mechanism and pharmacology properties. Re-analysis of gene expression profile could identify new potential targets, confirm a current implication, and expand the chance of repurposing drugs for osteosarcoma treatment.

Abstract
Research on the implications of ferroptosis in tumors has increased rapidly in the last decades. There are evidences that ferroptosis is involved in several aspects of cancer biology, including tumor progression, metastasis, immunomodulation, and therapeutic response. Nonetheless, the interaction between ferroptosis-related lncRNAs (FRLs) and the osteosarcoma immune microenvironment is poorly understood. In this study, a risk model composed of FRLs was developed using univariate and LASSO Cox regression analyses. On the basis of this model, FRL scores were calculated to systematically explore the role of the model in predicting the prognosis and immune characteristics of osteosarcoma patients. Survival analysis showed that osteosarcoma samples with lower FRL-score had better overall survival. After predicting the abundance of immune cells in osteosarcoma microenvironment by single-sample gene-set enrichment analysis (ssGSEA) and ESTIMATE analysis, we found that the FRL-score could distinguish immune function, immune score, stromal score, tumor purity, and tumor infiltration of immune cells in different osteosarcoma patients. In addition, FRL-score was also associated with immune checkpoint gene expression and half-maximal inhibitory concentration of chemotherapeutic agents. Finally, we confirmed that knockdown of RPARP-AS1 suppressed the malignant activity of osteosarcoma cells in vitro experiments. In general, the FRL-based prognostic signature could promote our understanding of the immune microenvironment characteristics of osteosarcoma and guide more effective treatment regimens.

Abstract
OBJECTIVE Osteosarcoma is the most frequent primary bone malignancy, associated with frequent recurrence and lung metastasis. RNA-binding proteins (RBPs) are pivotal in regulating several aspects of cancer biology. Nonetheless, interaction between RBPs and the osteosarcoma immune microenvironment is poorly understood. We investigated whether RBPs can predict prognosis and immunotherapy response in osteosarcoma patients. METHODS We constructed an RBP-related prognostic signature (RRPS) by univariate coupled with multivariate analyses and verified the independent prognostic efficacy of the signature. Single-sample Gene Set Enrichment Analysis (ssGSEA) along with ESTIMATE analysis were carried out to investigate the variations in immune characteristics between subgroups with various RRPS-scores. Furthermore, we investigatedpossible small molecule drugs using the connectivity map database and validated the expression of hub RBPs by qRT-PCR. RESULTS The RRPS, consisting of seven hub RBPs, was an independent prognostic factor compared to traditional clinical features. The RRPS could distinguish immune functions, immune score, stromal score, tumor purity and tumor infiltration by immune cells in different osteosarcoma subjects. Additionally, patients with high RRPS-scores had lower expression of immune checkpoint genes than patients with low RRPS-scores. We finally identified six small molecule drugs that may improve prognosis in osteosarcoma patients and substantiated notable differences in the contents of these RBPs. CONCLUSION We evaluated the prognostic value and clinical application of an RBPs-based prognostic signature and identified promising biomarkers to predict immune cell infiltration and immunotherapy response in osteosarcoma.

Abstract
5-Fluorouracil (5-FU) is a common chemotherapy drug for patients with advanced colorectal cancer; however, many patients develop resistance to 5-FU and suffer from treatment failure. Discoidin domain receptor 1 (DDR1) is upregulated in multiple cancers and positively associated with chemoresistance. We explored the effect of DDR1a on the cytotoxicity induced by 5-FU in LoVo cells and the underlying mechanism. Therefore, DDR1a overexpression (DDR1ahigh) and knockdown in LoVo cell lines (shDDR1a) were constructed to detect cell viability and cytotoxicity induced by 5-FU. The results showed that cell viability of DDR1ahigh cells was higher in comparison with that of the control group. When 5-FU (5 µM) was administered, the percentage of apoptotic cells, cytochrome C release and caspase-3 activity was found to be higher in the shDDR1a group than that in the control group. Both of PI3K and MDM2 proteins level decreased in DDR1ahigh and shDDR1a, but the BAX/Bcl-2 level in the shDDR1a group increased compared to that in the control. Therefore, DDR1a might be a potential therapeutic target for 5-FU chemoresistance in colorectal cancer.

Abstract
Homeodomain‑containing gene 10 (HOXC10) has been identified as an oncogene in various malignancies. Nevertheless, the role and function of HOXC10 in breast cancer (BC) remain unclear. RT-qPCR and Western blot were used to detect the mRNA and protein levels of genes, respectively. CCK-8, transwell, and TUNEL assays were performed to evaluate cell viability, invasion, migration, and apoptosis of BC cells in vitro. The xenograft model was established to examine the effect of HOXC10 on tumor growth in vivo. Our results indicated that HOXC10 expression was increased in BC and correlated with an unsatisfactory prognosis. Functional assays indicated that HOXC10 overexpression promoted cell proliferation and metastasis, and suppressed cell apoptosis of BC, while HOXC10 knockdown showed opposite trends. Furthermore, in vitro and in vivo assays uncovered that HOXC10 promoted the tumorigenesis of BC via the activation of IL-6/JAK2/STAT3 signaling. Overall, our study revealed that HOXC10 could function as a tumor promotor in BC by upregulating IL-6 levels to activate the JAK2/STAT3 signaling pathway.

Abstract
The HOXC10 gene, a member of the HOX genes family, plays crucial roles in mammalian physiological processes, such as limb morphological development, limb regeneration, and lumbar motor neuron differentiation. HOXC10 is also associated with angiogenesis, fat metabolism, and sex regulation. Additional evidence suggests that HOXC10 dysregulation is closely associated with various tumors. HOXC10 is an important transcription factor that can activate several oncogenic pathways by regulating various target molecules such as ERK, AKT, p65, and epithelial mesenchymal transition-related genes. HOXC10 also induces drug resistance in cancers by promoting the DNA repair pathway. In this review, we summarize HOXC10 gene structure and expression as well as the role of HOXC10 in different human cancer processes. This review will provide insight into the status of HOXC10 research and help identify novel targets for cancer therapy.

Abstract
Purpose: Dysregulation of microRNAs (miRNAs) contributes to tumor progression via the regulation of the expression of specific oncogenes and tumor suppressor genes. One such example, miR-27b-3p, has reportedly been involved in tumor progression in many types of cancer. The aim of the present study was to delve into the role and the underlying mechanism of miR-27b-3p in colorectal cancer (CRC) cells. Methods: In the present study, we detected the expression level of miR-27b-3p by RT-PCR. The effect of miR-27b-3p overexpression on cell proliferation in CRC cells was evaluated by cell counting and Edu assays. Transwell migration and invasion assays were used to examine the effects of cell migration and invasion. Bioinformatics, luciferase reporter assay and western blot assay were performed to identify the target of miR-27b-3p. Results: Here, we have demonstrated that although miR-27b-3p can affect cell morphology, it has no observable effect on the proliferation of CRC cells. However, it significantly promotes the migration and invasion of CRC cells. We discovered that HOXA10 was a newly identified target of miR-27b-3p in CRC cells, as confirmed by bioinformatics, western blots and dual luciferase reporter assay. Furthermore, the overexpression of miR-27b-3p or the suppression of HOXA10 can activate the integrin β1 signaling pathway. In conclusion, our results reveal a new function of miR-27b-3p that demonstrates its ability to promote CRC cell migration and invasion by targeting the HOXA10/integrin β1 cell signal axis. Conclusion: This may provide a mechanism to explain why miR-27b-3p promotes CRC cell migration and invasion.

Abstract
The mortality rate of ovarian cancer is the highest among gynaecological cancers, primarily due to metastatic symptoms. Recent studies have shown that HOX genes are crucial in tumour progression, but the underlying mechanisms remain unclear. Here, HOXC10 expression was examined in ovarian cancer tissues. The function of HOXC10 in ovarian cancer metastasis was investigated in vitroand via intraperitoneal injection in vivo. A total of 158 ovarian cancer patients with adequate records were enrolled for analysis. HOXC10 was associated with metastasis and poor prognosis in ovarian cancer. In vitro, HOXC10 overexpression promoted ovarian cancer cell migration. Moreover, HOXC10 positively regulated Slug expression, altering the migration ability of cancer cells. Furthermore, our study showed that miR-222-3p was a suppressor of HOXC10. In vivo, a decrease in hepatic metastasis was seen in xenograft mice harbouring tumours with stable HOXC10 overexpression after miR-222-3p agomir (an overexpression reagent) injection. This study provides the first evidence that HOXC10 promotes ovarian cancer metastasis by regulating the transcription of the EMT-related gene Slug. Moreover, we found that HOXC10 is regulated by miR-222-3p. These data highlight the crucial role of HOXC10 in enhancing ovarian cancer metastasis and may provide a therapeutic target for ovarian cancer.

Abstract
The homeobox genes (HOX) have emerged as a new family of master regulators of development and cancer. In the current study, we examined the expression and function of HOXC10 in human non-small cell lung cancer (NSCLC). We observed increased expression of HOXC10 in the more aggressive human NSCLC cell line NCI-H23 over the well differentiated A549 cells. To elucidate the expression and function of HOXC10 in NSCLC cells, we employed RT-PCR, immunoblotting, methylation-specific PCR, apoptosis assays, and xenograft model. Overexpression of HOXC10 in A549 cells conveyed increased proliferation, reduced apoptosis, and accelerated tumor growth when transplanted into nude mice. In contrast, siRNA-mediated knockdown of HOXC10 in NCI-H23 cells reduced proliferation and increased apoptosis. Our results further indicated that hypomethylation of the CpG island in the HOXC10 promoter was critical to elevated expression of HOXC10 in NSCLC cells. Lastly, we identified a G-quadruplex in the HOXC10 promoter and its G-quadruplex formation was required for elevated expression of HOXC10 in NSCLC cells. Moreover our results suggest that disruption of G-quadruplex formation can silence HOXC10 expression in NSCLC cells. In summary, we report HOXC10 as a novel tumor promoting oncogene in NSCLC cells.

[PMID: 32552008 DOI: 10.1089/cbr.2019.3107] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/21/2023] Open
Abstract
Background: Repeated administration of apatinib has resulted in serious drug resistance in gastric cancer (GC). Previous studies showed that miR-129-5p had a low expression in GC, and homeobox gene C10 (HOXC10), a carcinogenic gene, was highly expressed in GC, while the molecular mechanism of miR-129-5p involved in apatinib resistance in GC cells is still unclear. Materials and Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression levels of miR-129-5p and HOXC10 in GC tissues or cell lines. The expression levels of associated proteins were detected by Western blot. Cell counting kit-8 (CCK-8), the 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT), and flow cytometry assays were conducted to detect cell viability, proliferation, and apoptosis of MGC-803/AP and AGS/AP cells in vitro. The dual-luciferase reporter assay was used to verify the targeted relationship between miR-129-5p and HOXC10. The xenograft model was established to examine the effect of miR-129-5p in vivo, and the HOXC10 protein expression in tumor xenograft was assessed by immunohistochemistry. Results: MiR-129-5p had a low expression in GC tissues and apatinib-resistant cell lines, while HOXC10 was highly expressed. Meanwhile, overexpression of miR-129-5p and knockdown of HOXC10 could enhance the chemosensitivity of MGC-803/AP and AGS/AP cells. Dual-luciferase reporter assay confirmed miR-129-5p targeted HOXC10 and downregulated its expression level. MiR-129-5p inhibited proliferation and promoted apoptosis of MGC-803/AP and AGS/AP cells by downregulating HOXC10. The experiment in vivo also confirmed that miR-129-5p reduced apatinib resistance in GC cells by targetedly inhibiting HOXC10. HOXC10 was upregulated in GC tumor xenograft tissues. Conclusion: miR-129-5p restrains apatinib-resistant of GC cells by regulating HOXC10.

MiR-129-5p induces cell cycle arrest through modulating HOXC10/Cyclin D1 to inhibit gastric cancer progression. FASEB J 2020; 34:8544-8557. [PMID: 32356314 DOI: 10.1096/fj.201903217r] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2019] [Revised: 04/14/2020] [Accepted: 04/16/2020] [Indexed: 02/07/2023]
Abstract
MicroRNAs (miRNAs) play important roles in posttranscriptional regulation and may serve as targets for the diagnosis and treatment of cancers. Nevertheless, a comprehensive understanding of miRNAs profiles in gastric cancer progression is still lacking. Here, we report that miR-129-5p is downregulated in gastric cancer by analyzing TCGA database (n = 41) and clinical tumor samples (n = 60). MiR-129-5p transfection suppressed gastric cancer cell proliferation through inducing G1 phase arrest in vitro and inhibit xenograft tumor growth in vivo. MiR-129-5p directly targeted the 3' untranslated regions (3' UTR) of HOXC10 mRNA and downregulated its expression. Importantly, miR-129-5p could reverse the oncogenic effect induced by HOXC10. We systemically screened the downstream target of HOXC10 by ChIP sequencing, and found that HOXC10 could transcriptionally regulate the expression of Cyclin D1 and facilitate G1/S cell cycle transition. Notably, high levels of HOXC10 and Cyclin D1 were related with poor prognosis of gastric cancer patients (n = 90). These findings reveal a novel role of miR-129-5p/HOXC10/Cyclin D1 axis in modulating cell cycle and gastric tumorigenesis, which might provide potential prognostic biomarkers and therapeutic targets for gastric cancer patients.

Abstract
Homeodomain-containing gene C10 (HOXC10), known to regulate cell differentiation and proliferation, is a key negative regulator in the browning of white adipose tissue in mice. Sheep is an important farm animal that provides meat for human consumption, with fat content being an important meat quality determinant; however, there is no report about the role of HOXC10 in sheep adipocytes or adipogenesis. In this study, we investigated the effect of HOXC10 on proliferation and adipogenic differentiation in sheep bone marrow mesenchymal stem cells (sBMSCs). In sBMSCs, HOXC10 overexpression promoted cell proliferation and upregulated the expression of p-PI3K, p-AKT, p-p70S6K, p-MEK, and p-ERK, whereas HOXC10 knockdown was associated with the opposite effects. These results suggested that HOXC10 may promote cell proliferation by activating the MEK/ERK and PI3K/AKT/mTOR/p70S6K signaling pathways. In addition, we found that HOXC10 expression was negatively associated with lipid accumulation in adipogenic-differentiated sBMSCs. HOXC10 overexpression in sBMSCs significantly decreased lipid droplet accumulation and suppressed the expression of adipogenic-specific genes, including ACC, LPL, PPARG, and FABP4, while HOXC10 knockdown was associated with the opposite effects. Furthermore, our study suggested a new regulatory mechanism of the effect of HOXC10 on lipid accumulation and metabolism; HOXC10 may negatively regulate lipid accumulation in adipogenic-differentiated sBMSCs, at least in part, by suppressing LPL expression. Overall, our research not only contributes to a better understanding of the mechanism of lipid accumulation and metabolism in sheep, but also shed light on meat quality control in the future.

Abstract
Homeodomain‑containing gene 10 (HOXC10) is a member of the homeobox transcription factors that plays an important role in the development of multicellular organisms. HOXC10 is overexpressed in a variety of human cancers, and recent studies have revealed that HOXC10 is upregulated in gastric cancer as well. However, its mechanism of action is not fully understood, thus, the role of HOXC10 was investigated in the present study in human gastric cancer. First, HOXC10 expression was revealed to be significantly increased in gastric cancer tissues compared to normal tissues (TCGA dataset), and HOXC10 upregulation was associated with decreased recurrence‑free survival in gastric cancer patients in a public gene expression dataset. HOXC10 promoted cell proliferation and metastasis in two gastric cancer cell lines (AGS and MKN74). Analyzing TCGA 450K DNA methylation dataset, it was revealed that HOXC10 CpG sites were hypomethylated in gastric cancer tissues. Bisulfite sequencing revealed that CpG sites in the HOXC10 first intronic region were hypomethylated in three gastric cancer tissues, and HOXC10 expression was increased in gastric cancer cell lines (AGS and SNU620) in response to 5‑azacytidine treatment. By RNA‑sequencing of AGS cells with ectopic HOXC10 expression, it was revealed that many genes were upregulated by HOXC10 overexpression. Among them, CST1 was predicted to be a HOXC10 direct target gene via prediction of HOXC10 binding sites from the JASPAR database. A chromatin immunoprecipitation assay revealed that HOXC10 directly bound to CST1 promoter regions. The present study proposes HOXC10 is a potential prognostic marker or therapeutic target in human gastric cancer.

Abstract
Homeobox gene C10 (HOXC10), known to regulate cell differentiation and proliferation, is upregulated in gastric cancer (GC). The mechanism underlying HOXC10 involvement in GC metastasis is unclear. Herein, we found that HOXC10 is overexpressed in GC relative to normal controls. In the 73 GC patients tissue microarrays (TMA) tested, HOXC10 expression was closely related with tumor-node-metastasis (TNM) stage, lymph node metastasis, and distant metastasis. HOXC10 overexpression tended to associate with low 5-year cumulative survival. Cox regression analysis identified HOXC10 as an independent prognostic factor for poor patient survival. HOXC10 promoted GC cell invasion and migration, regulated the expression of activated ATM and markers of NF-κB signaling. HOXC10 may promote invasion and migration of GC by regulating ATM/NF-κB signaling pathway. HOXC10 should be explored as a clinical marker of GC prognosis.

Abstract
BACKGROUND The detection of molecules and mechanisms affecting the malignant phenotype of gastric cancer cells may contribute to the identification of biomarkers for metastasis and recurrence, and such molecules may serve as targets of therapy. For this purpose, in this study transcriptome analysis was performed using surgically resected specimens from patients with gastric cancer with synchronous metastasis. We identified homeobox C10 (HOXC10) as the most highly expressed gene in gastric cancer tissues compared with the adjacent noncancerous gastric mucosa. METHODS Polymerase chain reaction (PCR) array analysis was performed to identify genes coordinately expressed with HOXC10. The effects of inhibiting HOXC10 on malignant phenotype was evaluated using HOXC10 knockout gastric cancer cell lines, and antibody array analysis was performed to assess the effect of HOXC10 knockout on intracellular signaling. We used a mouse subcutaneous xenograft model to evaluate the tumorigenicity. HOXC10 expression was determined in gastric cancer tissues acquired from 300 patients with gastric cancer. RESULTS PCR array analysis revealed that the levels of HOXC10 messenger RNA positively correlated with those of FGFBP1 and SOX10. The phosphorylation of ERK1/2 was decreased in HOXC10 knockout cells. HOXC10 knockout significantly suppressed proliferation by increasing apoptosis and reducing the migration and invasiveness of gastric cancer cells. Mouse xenograft models revealed that the tumorigenicity of HOXC10 knockout cells was attenuated compared with the parental cells. The relatively high expression levels of HOXC10 in gastric cancer tissues were significantly associated with hepatic and peritoneal recurrence, as well as worse prognosis. CONCLUSIONS Our results indicated that HOXC10 enhances the malignant phenotype of gastric cancer cells. The expression levels of HOXC10 may therefore serve as a prognostic biomarker and the products of HOXC10 may provide targets of therapy.
