Abstract
In recent years, accumulating evidence has demonstrated the role of long noncoding RNAs (lncRNAs) in colon cancer. We aim to investigate the role of MIR143HG, also known as CARMN (Cardiac mesoderm enhancer-associated noncoding RNA) in colon cancer and explore the related mechanisms. An RNAseq data analysis was performed to screen differentially expressed lncRNAs associated with colon cancer. Next, MIR143HG expression was quantified in colon cancer cells. Moreover, the contributory roles of MIR143HG in the progression of colon cancer with the involvement of DNMT1 and HOXB7 (Homeobox B7) were evaluated after restored MIR143HG or depleted HOXB7. Finally, the effects of MIR143HG were investigated in vivo by measuring tumor formation in nude mice. High-throughput transcriptome sequencing was employed to validate the specific mechanisms by which MIR143HG and HOXB7 affect tumor growth in vivo. MIR143HG was found to be poorly expressed, while HOXB7 was highly expressed in colon cancer. MIR143HG could promote HOXB7 methylation by recruiting DNMT1 to reduce HOXB7 expression. Upregulation of MIR143HG or downregulation of HOXB7 inhibited cell proliferation, invasion and migration and facilitated apoptosis in colon cancer cells so as to delay the progression of colon cancer. The same trend was identified in vivo. Our study provides evidence that restoration of MIR143HG suppressed the progression of colon cancer via downregulation of HOXB7 through DNMT1-mediated HOXB7 promoter methylation. Thus, MIR143HG may be a potential candidate for the treatment of colon cancer.

Abstract
The homeobox family genes are often dysregulated in various cancer types. Particularly HOXB7 amplification and overexpression correlate with poor prognosis in various cancer such as gastric, pancreatic, and lung cancers. Moreover, HOXB7 is known to contribute to cancer progression by promoting epithelial to mesenchymal transition, anticancer drug resistance, and angiogenesis. In this study, we show that HOXB7 is coamplified with ERBB2 in a subset of breast cancer patients and HOXB7 expression correlates with poor prognosis in HER2-positive breast cancer patients. This clinical observation is supported by the following results-HOXB7 overexpression in an immortalized murine mammary gland epithelial cell line NMuMG induces cellular transformation in vitro, tumorigenesis, and lung metastasis through the activation of JAK-STAT signaling.

Int J Mol Sci 2022; 23:ijms23158646. [PMID: 35955781 PMCID: PMC9369439 DOI: 10.3390/ijms23158646] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 07/27/2022] [Accepted: 07/28/2022] [Indexed: 11/16/2022] Open
Abstract
Junctional adhesion molecules (JAMs; comprising JAM-A, -B and -C) act as receptors for viruses, mediate cell permeability, facilitate leukocyte migration during sterile and non-sterile inflammation and are important for the maintenance of epithelial barrier integrity. As such, they are implicated in the development of both communicable and non-communicable chronic diseases. Here, we investigated the expression and regulation of JAM-B in leukocytes under pathogen- and host-derived inflammatory stimuli using immunoassays, qPCR and pharmacological inhibitors of inflammatory signalling pathways. We show that JAM-B is expressed at both the mRNA and protein level in leukocytes. JAM-B protein is localised to the cytoplasm, Golgi apparatus and in the nucleus around ring-shaped structures. We also provide evidence that JAM-B nuclear localisation occurs via the classical importin-α/β pathway, which is likely mediated through JAM-B protein nuclear localisation signals (NLS) and export signals (NES). In addition, we provide evidence that under both pathogen- and host-derived inflammatory stimuli, JAM-B transcription is regulated via the NF-κB-dependent pathways, whereas at the post-translational level JAM-B is regulated by ubiquitin-proteosome pathways. Anaphase-promoting ubiquitin ligase complex (APC/C) and herpes simplex virus-associated ubiquitin-specific protease (HAUSP/USP) were identified as candidates for JAM-B ubiquitination and de-ubiquitination, respectively. The expression and regulation of JAM-B in leukocytes reported here is a novel observation and contrasts with previous reports. The data reported here suggest that JAM-B expression in leukocytes is under the control of common inflammatory pathways.

[PMID: 35080776 PMCID: PMC9304284 DOI: 10.1002/ijc.33949] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Revised: 12/24/2021] [Accepted: 01/07/2022] [Indexed: 11/07/2022]
Abstract
The HOX genes are a highly conserved group of transcription factors that have key roles in early development, but which are also highly expressed in most cancers. Many studies have found strong associative relationships between the expression of individual HOX genes in tumours and clinical parameters including survival. For the majority of HOX genes, high tumour expression levels seem to be associated with a worse outcome for patients, and in some cases this has been shown to result from the activation of pro-oncogenic genes and pathways. However, there are also many studies that indicate a tumour suppressor role for some HOX genes, sometimes with conclusions that contradict earlier work. In this review, we have attempted to clarify the role of HOX genes in cancer by focusing on their downstream targets as identified in studies that provide experimental evidence for their activation or repression. On this basis, the majority of HOX genes would appear to have a pro-oncogenic function, with the notable exception of HOXD10, which acts exclusively as a tumour suppressor. HOX proteins regulate a wide range of target genes involved in metastasis, cell death, proliferation, and angiogenesis, and activate key cell signalling pathways. Furthermore, for some functionally related targets, this regulation is achieved by a relatively small subgroup of HOX genes.

Abstract
BACKGROUND HOXB7 is abnormally expressed in a variety of tumors, but its prognostic value remains unclear due to sample size limitation and outcome inconsistency in previous studies. This meta-analysis was performed to explore the effect of HOXB7 expression on prognoses and clinicopathological factors in range of the whole solid tumors. METHODS PubMed, EMBASE, and Web of Science databases were searched to identify included studies. Hazard ratios (HR) with its 95% confidence interval (CI) and clinicopathological factors were extracted. Subgroup analyses were performed according to histopathological type, tumor occurrence systems, and HOXB7 detection methods. RESULTS A total of 3430 solid tumors patients from 20 studies (21 cohorts) were included in the meta-analysis. The results showed that high HOXB7 expression was significantly associated with worse survival (overall survival: HR = 1.98, 95%CI: 1.74-2.26, P < .001 and disease-free survival: HR = 1.59, 95%CI: 1.21-2.09, P = .001), more advanced tumor-node-metastasis (TNM) stage (odds ratio [OR] = 2.14, 95%CI: 1.68-2.73, P < .001), positive lymph node metastasis (OR = 2.16, 95%CI: 1.74-2.70, P < .001), more distant metastasis (OR = 1.63, 95%CI: 1.01-2.63, P = .048), poorer differentiation (OR = 1.48, 95%CI: 1.14-1.91, P = .003), and higher Ki-67 expression (OR = 2.53, 95%CI: 1.68-3.84, P < .001). Subgroup analysis showed that survival of patients with HOXB7 high expression was worse in either squamous cell carcinomas or non-squamous cell carcinomas, digestive tumors or non-digestive tumors, and protein level or mRNA level. CONCLUSION High HOXB7 expression might be a valuable biomarker of poor prognosis for solid tumors. HOXB7 promotes tumor proliferation and metastasis, and is associated with poorer differentiation, more advanced stage, even the chemotherapy resistance, suggesting that HOXB7 is a potential therapeutic target for solid tumors.

Abstract
Homeobox (HOX) genes encode highly conserved homeotic transcription factors that play a crucial role in organogenesis and tissue homeostasis. Their deregulation impacts the function of several regulatory molecules contributing to tumor initiation and progression. A functional bridge exists between altered gene expression of individual HOX genes and tumorigenesis. This review focuses on how deregulation in the HOX-associated signaling pathways contributes to the metastatic progression in cancer. We discuss their functional significance, clinical implications and ascertain their role as a diagnostic and prognostic biomarker in the various cancer types. Besides, the mechanism of understanding the theoretical underpinning that affects HOX-mediated therapy resistance in cancers has been outlined. The knowledge gained shall pave the way for newer insights into the treatment of cancer.

Abstract
Diffuse glioma is the most common primary tumor of the central nervous system. The prognosis of the individual tumor is heavily dependent on its grade and subtype. Homeobox B7 (HOXB7), a member of the homeobox family, is abnormally overexpressed in a variety of tumors. However, its function in glioma is unclear. In this study, HOXB7 mRNA and protein expression levels were analyzed in 401 gliomas from the CGGA RNA-seq database (325 cases) and our hospital (76 cases). HOXB7 expression, at both mRNA and protein levels, were upregulated in glioblastoma (GBM) and isocitrate dehydrogenase 1 (IDH1) wild-type glioma tissues. Kaplan–Meier with log-rank test showed that patients with high HOXB7 expression had a poor prognosis (p < 0.0001). Moreover, HOXB7 protein was deleted in 90.9% (20/22) of oligodendrogliomas and 13.0% (3/23) of astrocytomas. The sensitivity and specificity of HOXB7 protein deletion in oligodendroglioma were 90.9% (20/22) and 87.0% (20/23), respectively. To verify the reliability of using HOXB7 in differentiating oligodendroglioma, we used 1p/19q fluorescence in situ hybridization (FISH) testing as a positive control. The Cohen’s kappa coefficient of HOXB7 immunohistochemistry staining and 1p/19q FISH testing was 0.778 (95% CI: 0.594–0.962, p < 0.001). In conclusion, HOXB7 is an independent predictor of poor prognosis in all grade gliomas. Additionally, HOXB7 is also a highly sensitive and specific indicator to differentiate oligodendroglioma from astrocytoma.

Abstract
BACKGROUND An increasing number of studies have described the aberrant expression of homeobox (HOX) proteins in gastric cancer (GC), which is critically associated with the prognosis and clinicopathological characteristics of GC. This study was conducted to investigate the clinical value and action mechanisms of HOX proteins in GC. METHODS A comprehensive search of PubMed, Embase, Web of Science and Cochrane Library was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. The pooled hazard ratio (HR) with its 95% confidence interval (95% CI) and the pooled odds ratio (OR) with its 95% CI were used to assess the effect of HOX protein expression on the prognosis and clinicopathological features of GC, respectively. RESULTS Nineteen studies containing 3775 patients were selected for this study. Heterogeneity among HRs of overall survival (OS) was markedly high (I2 = 90.5%, p = 0.000). According to the subgroup analysis, increased expression of HOX protein in the downregulated subgroup was associated with a good prognosis for patients with GC (pooled HR: 0.46, 95% CI: 0.36-0.59, I2 = 3.1%, p = 0.377), while overexpression of HOX protein in the upregulated subgroup was correlated with a reduced OS (pooled HR: 2.59, 95% CI: 1.79-3.74, I2 = 73.5%, p = 0.000). The aberrant expression of HOX protein was crucially related to the TNM stage, depth of tumour invasion, tumour size, lymph node metastasis, distant metastasis, vascular invasion, histological differentiation and Lauren classification in patients with GC. In addition, the molecular mechanisms by which HOX proteins regulate tumorigenesis and development of GC were also explored. CONCLUSIONS HOX proteins play vital roles in GC progression, which might serve as prognostic markers and therapeutic targets for GC.

Abstract
BACKGROUND AND AIM Our study aimed to investigate the ways by which HOXB7 affects gastric cancer progression and oxaliplatin (L-OHP) resistance. METHODS First, the expression of HOXB7 in paired cancer and paracancerous tissues of L-OHP-sensitive and L-OHP-resistant gastric cancer patients was qualitatively and quantitatively analyzed by immunohistochemistry. Then, the expression of HOXB7 in these tissues was further quantitatively analyzed at protein and transcriptional levels. The expression of HOXB7 in the SGC-7901 L-OHP-resistant gastric cancer cell line was further verified by immunofluorescence, western blot, and RT-qPCR. In addition, by transfecting the SGC-7901 cell line, control (sh-con) and HOXB-7-silenced (sh-HOXB7) gastric cancer cell lines were created. Subsequently, the migratory and invasive abilities of these cells were determined by the transwell assay. The proliferation rate of both control and HOXB-7-silenced cells induced by varying concentrations of L-OHP was detected by the CCK-8 assay, while the degree of apoptosis in the same cells induced by 60 µM L-OHP was detected by flow cytometry. RESULTS AND CONCLUSION Results suggested that HOXB7 was overexpressed in both the tissues of L-OHP-resistant gastric cancer patients and the SGC-7901 gastric cancer cell line. Moreover, HOXB7 promoted the migratory and invasive abilities of gastric cancer cells. By silencing HOXB7 protein expression, the proliferation rate of L-OHP-resistant gastric cancer cells decreased considerably, while their degree of apoptosis increased significantly. These results showed that HOXB7 promoted gastric cancer progression and L-OHP resistance.

Abstract
Purpose The present study aimed to investigate the impact of psoralen on miR-196a-5p expression and function, and to reveal the mechanism underlying miR-196a-5p-mediated inhibition and the reversal of cisplatin (DDP) resistance. Methods Serum samples were collected from 50 patients with gastric cancer (GC), and the association between miR-196a-5p expression and the response to chemotherapy was assessed. A DDP-resistant GC cell line was also established to determine the effects of miR-196a-5p and psoralen on DDP resistance. MGC803 cells were transfected with miR-196a-5p mimic and inhibitor vectors for the overexpression and downregulation of miR-196a-5p, respectively. Results Clinical data analysis showed that the lower expression levels of miR-196a-5p were significantly associated with chemoresistance in patients with GC. Upregulation of miR-196a-5p significantly enhanced the anti-proliferative effect, apoptosis and sensitivity to DDP by regulating the protein expression levels of HOXB7, HER2, Bcl-2 and G1/S-specific cyclin-D1 (CCND1). Furthermore, psoralen reversed miR-196a-5p-induced DDP resistance and reduced the expression levels of HOXB7, HER2, Bcl-2 and CCND1. Conclusion miR-196a-5p may be a novel biomarker of chemotherapeutic success in patients with GC and may also influence the sensitivity of GC cells to DDP. Moreover, psoralen can increase chemotherapeutic sensitivity by upregulating miR-196a-5p and then downregulating HOXB7-HER2 signaling axis.

FKBP10 functioned as a cancer-promoting factor mediates cell proliferation, invasion, and migration via regulating PI3K signaling pathway in stomach adenocarcinoma. Kaohsiung J Med Sci 2019; 36:311-317. [PMID: 31868996 DOI: 10.1002/kjm2.12174] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2019] [Accepted: 12/02/2019] [Indexed: 11/08/2022] Open
Abstract
As documented, the expression, biological roles, and prognostic significance of FKBP10 in stomach adenocarcinoma (STAD) have not been investigated till now. This drives us to detect the biological roles and clinical significance of FKBP10 in STAD. The expression level of FKBP10 was measured based on the data obtained from the TCGA, ONCOMINE, and GEPIA databases, and STAD cell lines. Through in vitro experiments, cell behaviors were investigated to evaluate the effects of FKBP10 on STAD. Moreover, the PI3K-AKT signaling pathway was measured. Relying on the data of TCGA, ONCOMINE, and GEPIA databases, and cancer cell lines, FKBP10 was up-regulated in STAD when compared with normals. The patients with low expression of FKBP10 had higher survival rate than those with high FKBP10 expression. After knockdown of FKBP10 in AGS cells, cell vitality, colony formation ability, and the migratory and invasive potential were inhibited. Western blotting analysis exhibited that knockdown of FKBP10 significantly reduced the expression level of p-AKT, and p-PI3K, but it did not influence the total expression level of AKT, and PI3K. FKBP10 might serve as a crucial player in gastric cancer, and targeting FKBP10 might provide clinical utility in gastric cancer in future.

Abstract
OBJECTIVE To investigate the effect of rosmarinic acid (RosA) on hepatocellular carcinoma cell in vivo and in vitro and to explore its possible mechanism of anti-hepatocarcinoma. METHODS The hepatocellular carcinoma cell line SMMC-7721 was treated with different concentrations of RosA (0, 20, 50, 100 μmol/L) to detect cell proliferation, cell cycle, apoptosis and invasion.PI3K pathway-specific activator IGF-1 was used to explore whether the mechanism for RosA action relates to PI3K/AKT signal pathway.Nude mice inoculated with SMMC-7721 cells were treated with different doses of RosA (0, 5, 10 and 20 mg/kg) to detect the tumor formation of cancer cells in vivo. RESULTS RosA significantly inhibited the proliferation of SMMC-7721 cells and induced G1 arrest and apoptosis in a dose-dependent manner. RosA might inhibit cell invasion by regulating epithelial-mesenchymal transition. Rescue experiments showed that IGF-1 could reverse the inhibition of PI3K/AKT/mTOR signal pathway by RosA and the effect on proliferation, apoptosis, cell cycle, invasion and EMT by IGF-1 in SMMC-7721 cells;RosA could inhibit tumor formation of SMMC-7721 cells in vivo. CONCLUSION RosA can inhibit the proliferation and invasion of hepatocellular carcinoma cell in vitro and inhibit tumour growth in vivo and the mechanism may relate to inhibiting the activation of PI3K/AKT signal pathway.

Abstract
BACKGROUND Gastric cancer (GC) is the fifth most common cancer and the third leading cause of cancer death worldwide. Identifying new targets for the treatment and predictive evaluation of GC is of great significance, especially for improving the prognosis. Few studies have focused on the clinical significance of homeobox B7 (HOXB7) expression in GC.
AIM To assess the prognostic value of HOXB7 expression in GC.
METHODS HOXB7 data were retrieved from the Oncomine GC database. The prognostic value of HOXB7 was assessed using an online survival analysis tool (KM Plotter database).
RESULTS Based on the Oncomine database, HOXB7 expression in GC was significantly higher than that in normal tissue (P < 0.05). Further analysis revealed that the expression of HOXB7 gene in both intestinal and diffuse GCs was significantly higher than that in normal tissue. Moreover, KM Plotters of overall survival indicated that high HOXB7 expression was closely associated with poor survival in GC (P < 0.05). Furthermore, high HOXB7 expression was also related with overall survival in different GC subtypes (Lauren subtype) (P < 0.05).
CONCLUSION High HOXB7 expression might be an important biological event during gastric oncogenesis, and could be a novel prognostic predictive factor for GC.

Abstract
Aim: To study the carcinogenetic mechanism of HOXB7 in gastric cancer (GC) remains. Methods: Two human GC cell lines — SGC7901 and SNU1 — were used for this study. SGC7901 cells were transfected with siRNA-HOXB7 (siHOXB7) to knock down HOXB7 expression, whereas, SNU1 cells were transduced with pCDNA3.1-HOXB7 to overexpress HOXB7. After transfection, cancer progression was assessed by determining cell proliferation, wound-healing process, cell cycle, apoptosis, invasion, and migration. The effect of HOXB7 on epithelial–mesenchymal transition (EMT) was measured by observing changes in F-actin cytoskeleton and evaluating the expression of EMT markers. p-Scr and p-FAK were evaluated to assess the mechanism. Results: Knockdown of HOXB7 suppressed cell proliferation, alleviated the wound-healing process, inhibited cell migration and invasion, and arrested the cell cycle while promoting cell apoptosis, suggesting the tumor-suppressive effect of siHOXB7 in human GC cells. On the contrary, HOXB7 overexpression showed a tumor-promoting effect on human GC cells. Moreover, we confirmed an inhibitory effect of siHOXB7 on the EMT process by preventing epithelial cells from acquiring a mesenchymal phenotype and downregulating mesenchymal markers (vimentin, β-catenin, N-cadherin, Twist) while upregulating epithelial markers (E-cadherin). Our data revealed that HOXB7 was associated with Src/FAK and favored the activation of the Src–FAK pathway in human GC cells. Conclusion: HOXB7 accelerated the malignancy of GC, by facilitating EMT and regulating the Scr–FAK pathway.

Abstract
OBJECTIVE To verify the feasibility of treating pressure ulcers (PUs) with autologous platelet-rich fibrin-based (PRF) bioactive membrane, both in vitro and in vivo. METHOD An animal model using adult male Sprague-Dawley rats was used. Pressure was periodically exerted on the skin to induce localised ischaemia by using an external magnet and transplanted metal disc. After a PU developed, the rats were divided into two groups: a treatment group and a control group. Rats in the treatment group were then treated with PRF bioactive membrane every three days. RESULTS A total of 20 rats were used in this study. At days three and seven, the PU area in the PRF bioactive membrane-treated group was significantly smaller than that in the control group, and after 14 days of treatment, the PUs in the PRF bioactive membrane treatment group had healed. Haemotoxylin and eosin staining, immunohistochemistry and Western blot results indicated that PRF bioactive membrane induced wound healing by increasing the thickness of the regenerated epidermis and by upregulating vascular endothelial growth factor expression. Further, we found that different concentrations of rat autologous PRF soluble factors extraction components could significantly promote rat aortic endothelial cell proliferation, wound healing and migration ability in vitro. CONCLUSION Overall, results indicate that PRF bioactive membrane promotes PU healing in rats. Thus, it may represent a natural and effective wound-healing tool for use in the treatment of clinical skin PUs in humans in the future.

Abstract
Homeobox B7 (HOXB7) protein is reported to be aberrantly expressed in a variety of cancers and to play an important role in multiple cellular processes. However, the specific mechanism by which HOXB7 promotes the malignant progression of intrahepatic cholangiocarcinoma (ICC) remains unclear. Therefore, we used quantitative real-time polymerase chain reaction (PCR) to detect the expression level of HOXB7 in 38 paired ICC tissue samples. Additionally, to assess correlation between HOXB7 and ICC prognosis, we performed immunohistochemistry (IHC) using 122 ICC tissues to detect HOXB7 expression. Cell Counting Kit-8 (CCK-8) and colony formation assays were employed to assess ICC cell proliferation, and Transwell assays were performed to estimate the invasion and migration abilities of ICC cells. The capillary tube formation assay was applied to explore the angiogenic effects of HOXB7. A xenograft tumor model was established in nude mice to assess the role of HOXB7 in tumor growth and lung metastasis. The results showed higher expression of HOXB7 in ICC tissues than in noncancerous tissues, and this increased expression was significantly associated with a poor prognosis. In addition, HOXB7 overexpression enhanced capillary tube formation, invasion and migration of ICC cells in vitro, whereas HOXB7 knockdown produced the opposite results in vitro. Moreover, the role of HOXB7 in promoting tumor growth and metastasis was verified in vivo. Further investigation revealed that the expression levels of MMP2, MMP9, VEGFa, and IL8 were elevated by HOXB7 and that the ERK pathway was activated. Our results demonstrate the prognostic value of HOXB7 and its role in metastasis and angiogenesis in ICC. HOXB7 upregulated MMP2, MMP9, VEGFa, and IL8 expression via the ERK pathway to accelerate the malignant progression of ICC.

Abstract
AIM To detect the mechanisms of Helicobacter pylori (H. pylori) infection in the invasion and metastasis of gastric cancer (GC).
METHODS Specimens from 99 patients with GC were collected. The correlation among H. pylori infection, heparanase (HPA) and mitogen-activated protein kinase (MAPK) expression, which was determined by immunohistochemistry, and the clinical features of GC was analysed using SPSS 22.0. Overall survival (OS) and relapse-free survival (RFS) of GC patients were estimated by the Kaplan-Meier method. Independent and multiple factors of HPA and MAPK with prognosis were determined with COX proportional hazards models. HPA and MAPK expression in MKN-45 cells infected with H. pylori was analysed using Western blot.
RESULTS H. pylori infection was observed in 70 of 99 patients with GC (70.7%), which was significantly higher than that in healthy controls. H. pylori infection was related to lymph metastasis and expression of HPA and MAPK (P < 0.05); HPA expression was relevant to MAPK expression (P = 0.024). HPA and MAPK expression in MKN-45 cells was significantly upregulated following H. pylori infection and peaked at 24 h and 60 min, before decreasing (P < 0.05). SB203580, an inhibitor of MAPK, significantly decreased HPA expression. HPA was related to lymph metastasis and invasive depth. HPA positive GC cases and H. pylori positive GC cases showed poorer prognosis than HPA negative cases (P < 0.05). COX models showed that the prognosis of GC was connected with HPA expression, lymph metastasis, tissue differentiation, and invasive depth.
CONCLUSION H. pylori may promote the invasion and metastasis of GC by increasing HPA expression that may associate with MAPK activation, thus causing a poorer prognosis of GC.

Abstract
Colorectal cancer (CRC) is one of the most common types of tumor worldwide. The morbidity and mortality rates of CRC have increased significantly in adults <50 years of age. In the present study, the effects of homeobox A6 (HOXA6) on the proliferation, apoptosis, migration and invasion of CRC cells were investigated. The results of reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis demonstrated that the expression of HOXA6 in CRC tumor tissue was higher than that in adjacent normal tissue. Appropriate cell lines and plasmids were selected by RT-PCR and western blot analyses, and recombinant plasmids were transfected into Caco2 or HT-29 cells. The results of RT-qPCR and western blot analyses demonstrated that the expression of HOXA6 was effectively enhanced, or inhibited, following transfection. The rate of cell proliferation was measured with cell counting kit-8, colony formation assay and 5-ethynyl‑2'-deoxyuridine assay, apoptosis was detected using terminal deoxynucleotidyl transferase dUTP nick end labeling and flow cytometry assays, and migration and invasion were evaluated using Transwell and wound-healing assays. The results demonstrated that the upregulation of HOXA6 promoted cell proliferation, migration and invasion, but inhibited apoptosis, whereas the downregulated expression of HOXA6 produced the opposite effects. In addition, the expression levels of apoptosis- and epithelial-mesenchymal transition (EMT)-related proteins were examined. The results of the western blot analysis revealed that the upregulated expression of HOXA6 suppressed the expression of B-cell lymphoma-2 (Bcl-2)-associated X protein, caspase-3, poly(ADP-ribose) polymerase and E-cadherin, but promoted the expression of Bcl-2, N-cadherin and Vimentin, whereas the opposite effect was observed in cells with downregulated HOXA6. These results indicated that HOXA6 regulated apoptosis through the Bcl-2 signaling pathway, and regulated migration and invasion through the EMT process. In conclusion, the present study confirmed that HOXA6 was involved in the regulation of CRC, which may inform the development of strategies for the diagnosis and treatment of CRC.

[PMID: 29576613 DOI: 10.1038/s41388-018-0229-9] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2017] [Revised: 01/31/2018] [Accepted: 02/28/2018] [Indexed: 12/24/2022]
Abstract
HOXB7 is a homeodomain (HOX) transcription factor involved in regional body patterning of invertebrates and vertebrates. We previously identified HOXB7 within a ten-gene prognostic signature for lung adenocarcinoma, where increased expression of HOXB7 was associated with poor prognosis. This raises the question of how HOXB7 overexpression can influence the metastatic behavior of lung adenocarcinoma. Here, we analyzed publicly available microarray and RNA-seq lung cancer expression datasets and found that HOXB7-overexpressing tumors are enriched in gene signatures characterizing adult and embryonic stem cells (SC), and induced pluripotent stem cells (iPSC). Experimentally, we found that HOXB7 upregulates several canonical SC/iPSC markers and sustains the expansion of a subpopulation of cells with SC characteristics, through modulation of LIN28B, an emerging cancer gene and pluripotency factor, which we discovered to be a direct target of HOXB7. We validated this new circuit by showing that HOXB7 enhances reprogramming to iPSC with comparable efficiency to LIN28B or its target c-MYC, which is a canonical reprogramming factor.

Abstract
INTRODUCTION Numerous studies have investigated the relationship between deregulated HOXB7 expression with the clinical outcome in patients with digestive stem cancers, HOXB7 has showed negative impacts but with varying levels. We aimed to comprehensively evaluate the prediction and prognostic value of HOXB7 in digestive stem cancers. EVIDENCE ACQUISITION Electronic databases updated to December 1st, 2016 were retrieved to collect relevant eligible studies to quantitatively explore the potential roles of HOXB7 as a prognostic indicator in digestive system cancers. EVIDENCE SYNTHESIS A total of 9 studies (N.=1298) was included in this synthetical meta-analysis. The pooled hazard ratios suggested that high expression of HOXB7 protein was associated with poor prognosis of OS in patients with digestive system cancers (HR=1.97, 95% CI: 1.65-2.28, P=0.000), and HOXB7 protein could act as an independent prognostic factor for predicting OS of patients with digestive system cancers (HR=2.02, 95% CI: 1.69-2.36, P=0.000). Statistical significance was also observed in subgroup meta-analysis based on the cancer type, histology type, country, sample size and publication date. Furthermore, we examined the correlations between HOXB7 protein and clinicopathological features. It showed that altered expression of HOXB7 protein was correlated with tumor invasion (P=0.000), lymph node status (P=0.000), distant metastasis (P=0.001) and TNM stage (P=0.000). However, the expression of HOXB7 protein was not associated with age (P=0.64), gender (P=0.40) or levels of differentiation (P=0.19). CONCLUSIONS High expression of HOXB7 protein was associated with poor prognosis of patients with digestive system cancers, as well as clinicopathologic characteristics, including the tumor invasion, lymph node status, distant metastasis and TNM stage. The expression of HOXB7 protein was not associated with age, gender or levels of differentiation. HOXB7 protein expression level in tumor tissue might serve as a novel prognostic marker for digestive system cancers.

Downregulation of HADH promotes gastric cancer progression via Akt signaling pathway. Oncotarget 2017; 8:76279-76289.

Abstract
HADH is a key enzyme in fatty acid oxidation. The aim of this study was to identify the role of HADH in gastric cancer. We analyzed the expression of HADH in 102 pairs of gastric cancer samples. Western blot analysis revealed that HADH was decreased in stage I/II gastric cancer samples compared to matched adjacent normal gastric tissue, and its expression was further decreased in stage III/IV samples. Importantly, the reduced expression of HADH was associated with increased expression of p-Akt and reduced expression of PTEN in the gastric carcinoma tumor samples. To determine the significance of HADH downregulation in gastric cancer progression, we tested the impact of HADH knockdown or overexpression on the migration and invasion of the gastric cancer cells using a transwell assay. Knockdown of HADH significantly promoted gastric cancer cell migration and invasion, which was associated with increased expression of p-Akt. The PI3K inhibitor LY294002 inhibited HADH shRNA induced migration/invasion, and abolished the upregulation of p-Akt. By contrast, HADH overexpression inhibited the migration and invasion of MKN45 cells. Herein, for the first time, we demonstrate that downregulation of HADH promotes gastric cancer progression via activation of Akt signaling pathway.

Abstract
Background Homeobox B7 (HOXB7) has been identified associated with poor prognosis of hepatocellular carcinoma (HCC). However, the specific mechanism by which HOXB7 promotes the malignant progression of HCC remains to be determined. Methods Immunohistochemistry (IHC) was used to detect the expression level of HOXB7 in 77-paired HCC tissue samples, and the correlation between HOXB7 and HCC prognosis was assessed. The location of HOXB7 was confirmed by immunofluorescence. Cell Titer-Blue assay was used to assess the proliferation of hepatoma cells. The stem-like properties of hepatoma cells were analysed by sphere formation and clone formation assays. The effect of HOXB7 on expression of cancer stem cell markers was evaluated. Transwell and wound-healing assays were performed to estimate the invasion and migration abilities of hepatoma cells. A xenograft tumor model was established in nude mice to assess the role of HOXB7 in tumor growth. Bioluminescence imaging was used to survey the effect of HOXB7 on the metastatic ability of hepatoma cells in vivo. Results Higher expression of HOXB7 was detected in HCC tissues compared with noncancerous tissues and significantly associated with poor prognosis of HCC. In addition, HOXB7 knockdown suppressed the cell proliferation, clone formation, sphere formation, invasion and migration of hepatoma cells in vitro; conversely, these biological abilities of hepatoma cells were enhanced by HOXB7 overexpression. Moreover, the cancer stem cell markers EPCAM and NANOG were up-regulated by HOXB7. The role of HOXB7 in promoting tumor growth and metastasis was verified in vivo. Further investigation revealed that c-Myc and Slug expression was elevated by HOXB7 and the AKT pathway was activated. Conclusion Overexpression of HOXB7 was significantly correlated with poor prognosis of HCC. HOXB7 up-regulated c-Myc and Slug expression via the AKT pathway to promote the acquisition of stem-like properties and facilitate epithelial-mesenchymal transition of hepatoma cells, accelerating the malignant progression of HCC.

Abstract
Gastric cancer (GC) is one of the most common malignant tumors of the digestive system. The etiology of GC is complex, and much more attention should be paid to genetic factors. In this study, we explored the role and function of LINC00052 in GC. We applied qRT-PCR and Northern blot to detect the expression of LINC00052 and found it was highly expressed during GC. We also investigated the effects of LINC00052 on tumor prognosis and progression and found that LINC00052 indicated poor prognosis and tumor progression. By performing MTT, colony formation, and Transwell assays, we found that LINC00052 promoted MGC-803 cell proliferation and metastasis. Pull-down and RIP assays showed that LINC00052 could interact with β-catenin and methyltransferase SMYD2, and immunoprecipitation detection showed that LINC00052 promoted β-catenin methylation to maintain its stability, so as to activate the Wnt/β-catenin pathway. Furthermore, XAV939 (inhibitor of β-catenin) was used to treat MGC-803 cells, and we found that LINC00052 promoted proliferation and metastasis, possibly by activation of the Wnt/β-catenin pathway. In conclusion, our research demonstrated a carcinogenic role for LINC000052 in GC, which may represent a new approach for the prevention and therapy of this cancer.
