Ortiz N, Díaz C. Preclinical evaluation of fenretinide against primary and metastatic intestinal type‑gastric cancer. Oncol Lett 2024; 28:561. [PMID: 39372665 PMCID: PMC11450695 DOI: 10.3892/ol.2024.14694] [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: 05/15/2024] [Accepted: 08/20/2024] [Indexed: 10/08/2024] Open
Abstract
In recent years there has been a decline in the incidence of gastric cancer, however the high mortality rate has remained constant. The present study evaluated the potential effects of the retinoid fenretinide on the viability and migration of two cell lines, AGS and NCI-N87, that represented primary and metastatic intestinal gastric cancer subtypes, respectively. It was determined that a similar2 dose of fenretinide reduced the viability of both the primary and metastatic cell lines. In addition, it was demonstrated that combined treatment with fenretinide and cisplatin may affect the viability of both primary and metastatic gastric cancer cells. Furthermore, a wound healing assay demonstrated an inhibitory effect for fenretinide on cell migration. As part of the characterization of the mechanism of action, the effect of fenretinide on reactive oxygen species production and lipid droplet content was evaluated, with the latter as an indirect means of assessing autophagy. These results support the hypothesis of combining using fenretinide with conventional therapies to improve survival rates in advanced or metastatic gastric cancer.

Abstract
Emerging therapeutic methods represented by targeted therapy are effective supplements to traditional first-line chemoradiotherapy resistance. Human epidermal growth factor receptor 2 (HER2) is one of the most important targets in targeted therapy for gastric cancer. Trastuzumab combined with chemotherapy has been used as the first-line treatment for advanced gastric cancer. The safety and efficacy of pertuzumab and margetuximab in the treatment of gastric cancer have been verified. However, monoclonal antibodies, due to their large molecular weight, inability to penetrate the blood-brain barrier, and drug resistance, lead to decreased therapeutic efficacy, so it is necessary to explore the efficacy of other HER2-targeting therapies in gastric cancer. Small-molecule tyrosine kinase inhibitors, such as lapatinib and pyrrotinib, have the advantages of small molecular weight, penetrating the blood-brain barrier and high oral bioavailability, and are expected to become the drugs of choice for perioperative treatment and neoadjuvant therapy of gastric cancer after validation by large-scale clinical trials in the future. Antibo-drug conjugate, such as T-DM1 and T-DXd, can overcome the resistance of monoclonal antibodies despite their different mechanisms of tumor killing, and are a supplement for the treatment of patients who have failed the treatment of monoclonal antibodies such as trastuzumab. Therefore, after more detailed stratification of gastric cancer patients, various gastric cancer drugs targeting HER2 are expected to play a more significant role.

Abstract
Hepatocellular carcinoma (HCC) is a significant contributor to global cancer-related deaths, leading to high mortality rates. However, the pathogenesis of HCC remains unclear. In this research, by the bioinformatics data analysis, we found that elevated CSTB expression correlated with advanced disease and predicted diminished overall survival (OS) in HCC patients. We subsequently verified the oncogenic role of CSTB as well as the potential underlying mechanisms in HCC through a series of in vitro experiments, such as CCK-8 assays, cloning assays, flow cytometry, Transwell assays, and western blotting. Our findings illustrated that the silencing of CSTB effectively suppressed cellular proliferation by inducing cell cycle arrest in the G2 phase and impaired HCC cell invasion and migration by stimulating epithelial-mesenchymal transition (EMT). Additionally, we analyzed the pathways enriched in HCC using RNA sequencing and found that the ERK/AKT/mTOR signaling pathway was related to increased CSTB expression in HCC. Finally, we confirmed the tumorigenic role of CSTB via in vivo experiments. Thus, our findings revealed that silencing CSTB inhibited the HCC progression via the ERK/AKT/mTOR signaling pathway, highlighting new perspectives for investigating the mechanisms of HCC.

Abstract
Gastric cancer poses a significant health challenge, and exploring innovative therapeutic strategies is imperative. RNA interference (RNAi) has employed as an important therapeutic strategy for diseases by selectively targeting key pathways involved in diseases pathogenesis. Small interfering RNA (siRNA), a potent RNAi tool, possesses the capability to silence genes and downregulate their expression. This review provides a comprehensive examination of the potential applications of small interfering RNA (siRNA) and short hairpin RNA (shRNA), supplemented by an in-depth analysis of nanoscale delivery systems, in the context of gastric cancer treatment. The potential of siRNA to markedly diminish the proliferation and invasion of gastric cancer cells through the modulation of critical molecular pathways, including PI3K, Akt, and EMT, is highlighted. Besides, siRNA demonstrates its efficacy in inducing chemosensitivity in gastric tumor cells, thus impeding tumor progression. However, the translational potential of unmodified siRNA faces challenges, particularly in vivo and during clinical trials. To address this, we underscore the pivotal role of nanostructures in facilitating the delivery of siRNA to gastric cancer cells, effectively suppressing their progression and enhancing gene silencing efficiency. These siRNA-loaded nanoparticles exhibit robust internalization into gastric cancer cells, showcasing their potential to significantly reduce tumor progression. The translation of these findings into clinical trials holds promise for advancing the treatment of gastric cancer patients.

Abstract
Long non-coding RNA (lncRNA) ZFAS1 (zinc finger antisense 1) was demonstrated to play critical roles in various cancer progression. However, the functions of ZFAS in cervical cancers (CC) are unclear. Human CC cell lines were used for in vitro experiments. RT-qPCR (Real Time Quantitative PCR) was performed to detect the expression of ZFAS1, microRNA-190a-3p (miR-190a-3p) and Kruppel-like factor 6 (KLF6). Cell proliferation, invasion and migration assays were used to investigate biological behaviors of CC cells related to CC progression. The relationship of KLF6 to ZFAS1 and miR-190a-3p was analyzed by circRIP and luciferase reporter assay. In addition, in vivo experiment was carried out to explore the function of ZFAS1 in tumor growth of CC. The expression levels of ZFAS1 and KLF6 were both significantly elevated, while the expression of miR-190a-3p was inhibited in CC tumor tissues. In addition, ZFAS1 influenced CC tumor growth through miR-190a-3p. KLF6 was a target of miR-190a-3p and inhibited miR-190a-3p-induced CC tumor growth. Furthermore, KLF6 was negatively regulated by miR-190a-3p, but positively regulated by ZFAS1. Overexpression of ZFAS1 and inhibition of miR-190a-3p significantly increased the expression levels of KLF6. Finally, in vitro assays demonstrated that inhibition of ZFAS1 reduced CC tumor growth and the expression levels of KLF6, but increased the expression levels of miR-190a-3p. ZFAS1 could regulate CC pathogenesis via regulating the miR-190a-3p/KLF6 axis, which might be considered as new CC therapeutic targets.

Abstract
Purpose Gastric cancer has a high mortality rate worldwide. Although treatments, such as molecular-targeted therapy, have been introduced, the resulting long-term survival and prognosis remain unsatisfactory. Downregulation of the target genes using lentivirus-mediated short hairpin RNA (shRNA) can be an effective therapeutic strategy for patients with gastric cancer. Overexpressed vascular endothelial growth factor A (VEGF) in human gastric cancer cells can be an effective novel therapeutic target for human gastric cancer. Thus, this study aimed to evaluate the therapeutic effects of lentivirus-mediated knockdown of VEGF gene expression in human gastric cancer growth. Materials and Methods Specific shRNA sequences targeting VEGF were designed to construct a lentiviral expression vector. After human gastric carcinoma cells (cell line NCI-N87) were infected with the lentiviral vector, the therapeutic effects of the lentivirus-mediated shRNA targeting VEGF were analyzed both in vitro and in vivo. Results Stable suppression of VEGF gene expression in NCI-N87 cells using shRNA (ShVEGF) showed significant inhibition of cell proliferation, clonogenicity, and cell motility. ShVEGF also showed increased G0/G1 cell cycle arrest and apoptosis. In addition, in vivo results from nude mice xenografted ShVEGF showed significant inhibition of tumor growth. Assessing the therapeutic effects of intratumoral injection of lentivirus-targeting VEGF (Virus_VEGF) revealed that it significantly inhibited tumor growth compared to that in the Virus_Scramble or saline injection control groups. Conclusion The constructed ShVEGF showed significant inhibition of NCI-N87 gastric cancer cell growth both in vitro and in vivo. These experimental results suggest a novel therapeutic strategy for patients with gastric cancer using lentivirus-mediated shRNA targeting VEGF.

Abstract
Gastric cancer (GC) is one of the leading causes of cancer-related deaths worldwide. Accumulating evidence reveals the significance of long non-coding RNAs (lncRNAs) in various cancers. The current study aimed to evaluate the role of GATA6 antisense RNA 1 (GATA6-AS1) in the epithelial-mesenchymal transition (EMT) and lymph node metastasis (LNM) in GC. GC-related microarray datasets were initially retrieved from the GEO with differentially expressed lncRNAs screened, followed by evaluation of the regulatory relationship between Frizzled 4 (FZD4) and GATA6-AS1. The detailed regulatory mechanism by which GATA6-AS1 influences the Wnt/β-catenin signaling pathway and GC cell biological behaviors was investigated by treating SGC7901 cells with overexpressed GATA6-AS1, specific antisense oligonucleotide against GATA6-AS1, and lithium chloride (LiCl; activator of the Wnt/β-catenin signaling pathway). Finally, xenograft nude mice were used to assay tumor growth and LNM in vivo. GATA6-AS1 was poorly expressed, but FZD4 was highly expressed in GC tissues and cells. Elevated GATA6-AS1 reduced FZD4 expression by recruiting enhancer of zeste homolog 2 (EZH2) and trimethylation at lysine 27 of histone H3 (H3K27me3) to the FZD4 promoter region via the inactivated Wnt/β-catenin signaling pathway, whereby cell invasion, migration, and proliferation, tumor growth, and LNM in nude mice were reduced. Taken together, overexpressed GATA6-AS1 downregulated the expression of FZD4 to inactivate the Wnt/β-catenin signaling pathway, which ultimately inhibited GC progression.

Abstract
Hepatocellular carcinoma (HCC) is one of the most aggressive malignancies and lacks targeted therapies. Here, we reported a novel potential therapeutic target hematological and neurological expressed 1 like (HN1L) in HCC. First, HCC tissue microarray analysis showed that HN1L was frequently up-regulated in cancer tissues than that in normal liver tissues, which significantly associated with tumor size, local invasion, distant metastases, and poor prognosis for HCC patients. Functional studies demonstrated that ectopic expression of HN1L could increase cell growth, foci formation in monolayer culture, colony formation in soft agar and tumorigenesis in nude mice. In addition, HN1L could also promote HCC metastasis by inducing epithelial-mesenchymal transition. Inversely, silencing HN1L expression with shRNA could effectively attenuate its oncogenic function. We further showed that HN1L transcriptionally up-regulated methyltransferase like 13 (METTL13) gene in an AP-2γ dependent manner, which promoted cell proliferation and metastasis by up-regulating TCF3 and ZEB1. Importantly, administration of lentivirus-mediated shRNA interfering HN1L expression could inhibit tumorigenesis and metastasis in mice. Collectively, HN1L-mediated transcriptional axis AP-2γ/METTL13/TCF3-ZEB1 promotes HCC growth and metastasis representing a promising therapeutic target in HCC treatment.

The MTT analysis, cell cycle analysis, clonal formation, and apoptotic analysis were used to examine the functions of DNMT1 and miR-152 in lymphoma cells. Methylation-specific polymerase chain reaction (MSP) was used to examine the methylation of tumor suppressor genes. The dual luciferase assay and western blot were used to validate if DNMT1 is the target of miR-152. For the in vivo experiments, the lymphoma cells were injected into the nude mice for quantification of the tumor growth after transfection of miR-152 mimics. Knockdown of DNMT1 by shRNA (sh-DNMT1) in OCI-Ly10 and Granta-159 cells significantly upregulated the expression of tumor suppressor genes (SOCS3, BCL2L10, p16, p14, and SHP-1) via decreasing their methylation level. At the cellular level, we found sh-DNMT1 inhibited the proliferation, clonal formation and cell cycle progression and induced the cell apoptosis of lymphoma cells. Furthermore, we found miR-152 can downregulates the expression of DNMT1 via directly targeting the gene. Overexpression of miR-152 also increased the expression of tumor suppressor genes SOCS3 and SHP-1. And miR-152 also can inhibit the cell proliferation and induce the cell apoptosis. Moreover, we found overexpression of miR-152 significantly repressed the tumor growth with decreased DNMT1 expression and increased expression of tumor suppressor genes in vivo. Our study demonstrates that miR-152 can inhibit lymphoma growth via suppressing DNMT1-mediated silencing of SOCS3 and SHP-1. These data demonstrate a new mechanism for the development of NHL and this may provide a new therapeutic target for NHL.

Abstract
Previous studies have identified that perilipin-1 (PLIN1) is a highly specific marker for liposarcoma. However, its functions have yet to be fully elucidated. The aim of the present study was to investigate the potential role of PLIN1 in the proliferation, migration and apoptosis of liposarcoma cells. Short hairpin RNA was designed to inhibit PLIN1 levels. Cell proliferation was monitored by Cell Counting Kit‑8 assay and cell migration determined by wound healing assay. Flow cytometry was performed to assess the cell cycle distributions and apoptosis in liposarcoma cells. The results demonstrated that the expression of PLIN1 was significantly upregulated in liposarcoma tumor tissues compared with normal adipose tissues. Silencing of PLIN1 by short hairpin RNA significantly inhibited proliferation and migration and induced G1 phase cell cycle arrest and apoptosis in liposarcoma cell lines. It was identified that PLIN1 serves a crucial role in the pathogenesis and progression of liposarcoma and may be a potential therapeutic target for its clinical management.

Abstract
Notch1, a transmembrane receptor that has a notable role in gastric cancer (GC) as an oncogene, has been reported to be involved in doxorubicin resistance. Thus, Notch1 is a potential therapeutic target for GC. In the present study, the protein levels of Notch1 intracellular domain (NICD; a marker of Notch1 activation) in human GC cell lines and tumor tissues was measured by western blotting. Next, the effects of Notch1 depletion in SGC7901 cells were evaluated. Finally, the efficacy of Notch1 small interfering RNA (siRNA) combined with doxorubicin therapy for GC was examined in vitro and in vivo. The results revealed that NICD levels were high in GC cells, and that the inhibition of NICD by transfection with Notch1 siRNA induced apoptosis and inhibited proliferation. Ectopic downregulation of Notch1 expression enhanced the sensitivity of GC tumors to doxorubicin, which suppressed the development of GC. These data demonstrated that Notch1 was a significant regulator of cell proliferation and apoptosis in GC. Thus, the combination of doxorubicin with Notch1 siRNA is a potential strategy for the treatment of GC.

Abstract
BACKGROUND Hedyotis diffusa Willd. (HDW) is one of the renowned herbs often used in the treatment of gastric cancer (GC). However, its curative mechanism has not been fully elucidated. OBJECTIVE To systematically investigate the mechanisms of HDW in GC. METHODS A network pharmacology approach mainly comprising target prediction, network construction, and module analysis was adopted in this study. RESULTS A total of 353 targets of the 32 bioactive compounds in HDW were obtained. The network analysis showed that CA isoenzymes, p53, PIK3CA, CDK2, P27Kip1, cyclin D1, cyclin B1, cyclin A2, AKT1, BCL2, MAPK1, and VEGFA were identified as key targets of HDW in the treatment of GC. The functional enrichment analysis indicated that HDW probably produced the therapeutic effects against GC by synergistically regulating many biological pathways, such as nucleotide excision repair, apoptosis, cell cycle, PI3K/AKT/mTOR signaling pathway, VEGF signaling pathway, and Ras signaling pathway. CONCLUSIONS This study holistically illuminates the fact that the pharmacological mechanisms of HDW in GC might be strongly associated with its synergic modulation of apoptosis, cell cycle, differentiation, proliferation, migration, invasion, and angiogenesis.

Abstract
Suppressor of activator protein-1, regulated by interferon (SARI), is a novel basic leucine zipper containing type I IFN-inducible early response protein that plays an important regulatory role in a wide variety of tumors, including leukemia. However, the functional role of SARI in myeloid leukemia is not thoroughly understood. In this study, we discovered that knock-down of SARI expression suppressed cell growth and colony formation, inhibited invasion, enhanced imatinib (STI571)-mediated apoptosis, and induced G0/G1 and G2/M arrest in human K562 myeloid leukemia cells. Moreover, using immunoblotting, we provide evidence that silencing of SARI resulted in declined expression of cyclinD1 and cyclinA2, as well as down-regulation of mTOR, c-myc p-mTOR, p-PI3K (p85), p-Akt, p70-S6K, p-p70-S6K and NF-κB (p65) that involved in the PI3K/Akt/mTOR and NF-κB signaling pathways. Taken together, our results demonstrate that SARI functions as an oncogenic role in K562 myeloid leukemia cells through regulating the PI3K/Akt/mTOR and NF-κB signaling pathways.

Abstract
Overexpression of cyclin D is associated with the molecular tumorigenesis of gastric cancer. The purpose of the present study was to investigate the expression of cyclin D in human gastric cancer and to determine the potential correlations between cyclin D expression and clinicopathological characteristics of specific histological types, as well as its prognostic significance. In the present study, the expression of the cyclin D1 (CCND1), cyclin D2 (CCND2) and cyclin D3 (CCND3) genes in gastric cancer patients was explored using the Oncomine database, and their correlation with overall survival (OS) and progression-free survival (PFS) was evaluated using Kaplan-Meier analysis. The prognostic significance of CCND1 protein expression was evaluated by western blot analysis of 32 matched specimens of gastric adenocarcinomas and normal tissues obtained from patients treated at the National Cheng Kung University Hospital (Tainan, Taiwan). Analysis of the Oncomine cancer microarray database revealed that CCND1 gene expression was significantly increased in gastric intestinal-type adenocarcinoma, while CCND2 was significantly increased in diffuse gastric adenocarcinoma, gastric intestinal-type adenocarcinoma and gastric mixed adenocarcinoma. Kaplan-Meier analysis indicated that overexpression of CCND1 was associated with reduced OS and PFS. In addition, overexpression of CCND1 and downregulation of CCND2 were significantly correlated with receptor tyrosine-protein kinase erb-2-negative tumors and poor differentiation. The ratio of relative CCND1 expression (expressed as the CCND1/β-actin ratio) in tumor tissues compared with that in normal tissues was correlated with poor differentiation (P=0.0018). In summary, CCND1 overexpression is associated with shorter survival in patients with gastric cancer and with poorly differentiated tumors.

Abstract
The present study aimed to investigate the expression and role of transforming growth factor (TGF) ‑β‑activated protein kinase 1 (TAK1) in human gastric cancer. Immunohistochemistry was performed to investigate the expression of TAK1 in surgical specimens of human gastric cancer tissue and adjacent normal tissue. The association between TAK1 and clinicopathologic factors was analyzed and the association between TAK1 expression and the overall survival rates was evaluated using Kaplan‑Meier curves. In addition, the effect of the TAK1 selective inhibitor 5Z‑7‑oxozeaenol (OZ) on the biological characteristics of MGC803 human gastric cancer cells in vitro were investigated. The role of TAK1 in gastric cancer cell proliferation, apoptosis and invasion were determined by cell proliferation assays, flow cytometry analysis and transwell invasion assays, respectively. The findings of the present study demonstrated that the positive expression rate of TAK1 in gastric cancer and adjacent normal tissues was 70.5 and 25.9%, respectively. Furthermore, TAK1 expression was significantly associated with advanced N stage and pathological stage (P<0.05). Survival analysis of 139 patients with gastric cancer indicated a lower overall survival rate of patients in the TAK1‑positive group compared with the TAK1‑negative group (P<0.05). In addition, treatment with the TAK1 selective inhibitor OZ reduced the proliferation and invasion abilities of MGC803 cells and significantly reduced the expression levels of phosphorylated‑TAK1 (Thr187), nuclear p65, cyclin D1, Bcl‑2 apoptosis regulator and matrix metallopeptidase (MMP)9 (P<0.05). OZ treatment significantly increased the expression levels of cytosolic cytochrome c and cleaved caspase 3 and the apoptosis rate in MGC803 cells (P<0.05). In conclusion, these findings suggest that increased TAK1 expression may be involved in the progression of gastric cancer; therefore, TAK1 may be used as a future therapeutic target for gastric cancer treatment.

Abstract
Background: Metastatic hepatocellular carcinoma (HCC) is a highly aggressive tumor with limited treatment options. While sorafenib has recently been shown to provide a survival advantage in patients with advanced HCC, the overall outcomes such as time to progression (TTP) and overall survival (OS) ought to be further improved. To that end, several targeted agents aimed at amplified oncogenes such as HER2 and FGFR2 have recently been developed. In this study, we aimed to identify genetic markers in the form of copy number variations (CNVs) that influence clinical outcomes post-sorafenib treatment in advanced HCC patients. Methods: We surveyed 38 metastatic HCC patients who were treated with sorafenib for the presence of CNVs using the NanoString nCounter assay. Results: The median TTP and OS for all patients were 2.7 months (95% confidence interval [CI]: 2.0-3.3 months) and 13.4 months (95% CI: 8.4-18.4 months), respectively. Several genes previously implicated in liver cancer were amplified, including CCND1 (n = 4), CDKN1A (n = 2), KRAS (n = 2), MDM2 (n = 1), and ERBB2 (n = 1). However, we found no correlations between CNVs and survival in our sorafenib-treated patients. Conclusions: The clinical features and biomarkers that account for sensitivity to sorafenib in HCC are complicated and remain unclear. Further investigation to identify predictive biomarkers and therapeutic strategies, including combining sorafenib with other target agents, are warranted.

Abstract
Orthodontic pain is an inflammatory pain that is initiated by orthodontic force-induced vascular occlusion followed by a cascade of inflammatory responses, including vascular changes, the recruitment of inflammatory and immune cells, and the release of neurogenic and pro-inflammatory mediators. Ultimately, endogenous analgesic mechanisms check the inflammatory response and the sensation of pain subsides. The orthodontic pain signal, once received by periodontal sensory endings, reaches the sensory cortex for pain perception through three-order neurons: the trigeminal neuron at the trigeminal ganglia, the trigeminal nucleus caudalis at the medulla oblongata and the ventroposterior nucleus at the thalamus. Many brain areas participate in the emotion, cognition and memory of orthodontic pain, including the insular cortex, amygdala, hippocampus, locus coeruleus and hypothalamus. A built-in analgesic neural pathway—periaqueductal grey and dorsal raphe—has an important role in alleviating orthodontic pain. Currently, several treatment modalities have been applied for the relief of orthodontic pain, including pharmacological, mechanical and behavioural approaches and low-level laser therapy. The effectiveness of nonsteroidal anti-inflammatory drugs for pain relief has been validated, but its effects on tooth movement are controversial. However, more studies are needed to verify the effectiveness of other modalities. Furthermore, gene therapy is a novel, viable and promising modality for alleviating orthodontic pain in the future.

Elevated HOXA1 expression correlates with accelerated tumor cell proliferation and poor prognosis in gastric cancer partly via cyclin D1. JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2016; 35:15. [PMID: 26791264 PMCID: PMC4721151 DOI: 10.1186/s13046-016-0294-2] [Citation(s) in RCA: 53] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/03/2015] [Accepted: 01/13/2016] [Indexed: 11/10/2022]
Abstract
BACKGROUND HOXA1 is a member of the Homeobox gene family, which encodes a group of highly conserved transcription factors that are important in embryonic development. However, it has been reported that HOXA1 exhibits oncogenic properties in many malignancies. This study focused on the expression and clinical significance of HOXA1 in gastric cancer (GC). METHODS To assess the mRNA and protein expression of HOXA1 and cyclin D1 in GC tissues, we utilized qRT-PCR and western blotting, respectively. The effects of HOXA1 on GC cell proliferation, migration, and invasion, as well as xenograft tumor formation and the cell cycle were investigated in our established stable HOXA1 knockdown GC cell lines. The protein expression of HOXA1 and cyclin D1 was examined by immunohistochemistry using GC tissue microarrays (TMA) to analyze their relationship on a histological level. The Kaplan-Meier method and cox proportional hazards model were used to analyze the relationship of HOXA1 and cyclin D1 expression with GC clinical outcomes. RESULTS HOXA1 mRNA and protein expression were upregulated in GC tissues. Knockdown of HOXA1 in GC cells not only inhibited cell proliferation, migration, and invasion in vitro but also suppressed xenograft tumor formation in vivo. Moreover, HOXA1 knockdown induced changes in the cell cycle, and HOXA1 knockdown cells were arrested at the G1 phase, the number of cells in S phase was reduced, and the expression of cyclin D1 was decreased. In GC tissues, high cyclin D1 mRNA and protein expression were detected, and a significant correlation was found between the expression of HOXA1 and cyclin D1. Survival analysis indicated that HOXA1 and cyclin D1 expression were significantly associated with disease-free survival (DFS) and overall survival (OS). Interestingly, patients with tumors that were positive for HOXA1 and cyclin D1 expression showed worse prognosis. Multivariate analysis confirmed that the combination of HOXA1 and cyclin D1 was an independent prognostic indicator for OS and DFS. CONCLUSION Our data show that HOXA1 plays a crucial role in GC development and clinical prognosis. HOXA1, alone or combination with cyclin D1, may serve as a novel prognostic biomarker for GC.

Abstract
The growth rate and carrying capacity of a cell population are key to the characterization of the population's viability and to the quantification of its responses to perturbations such as drug treatments. Accurate estimation of these parameters necessitates careful analysis. Here, we present a rigorous mathematical approach for the robust analysis of cell count data, in which all the experimental stages of the cell counting process are investigated in detail with the machinery of Bayesian probability theory. We advance a flexible theoretical framework that permits accurate estimates of the growth parameters of cell populations and of the logical correlations between them. Moreover, our approach naturally produces an objective metric of avoidable experimental error, which may be tracked over time in a laboratory to detect instrumentation failures or lapses in protocol. We apply our method to the analysis of cell count data in the context of a logistic growth model by means of a user-friendly computer program that automates this analysis, and present some samples of its output. Finally, we note that a traditional least squares fit can provide misleading estimates of parameter values, because it ignores available information with regard to the way in which the data have actually been collected.

Abstract
Calcium-activated potassium ion channel-3.1 (KCa3.1) plays a pivotal role in the potassium-calcium exchange involved in atopy. This study aimed to explore the impact of lentiviral-mediated shRNA silencing KCa3.1 on allergic response in a murine allergic rhinitis (AR) model. The BALB/c mice were divided into four groups: untreated AR group, negative control AR group, lentiviral KCa3.1-shRNA treated AR group and normal control group. Concentrations of ovalbumin (OVA)-specific IgE, histamine and leukotrienes C4 (LTC4) in serum, and IL-4, IL-9 and IL-17 in nasal lavage fluid (NLF) were analyzed. Goblet cells and mast cells were counted. KCa3.1 positive cells were counted after immunolabelling by immunofluorescence method. KCa3.1, Mucin 5AC (MUC5AC), and tryptase mRNA levels were determined using real-time polymerase chain reaction. Furthermore, P815 cell line was used to explore the role and mechanism of lentiviral KCa3.1-shRNA on mast cells. The results showed that LV-KCa3.1-shRNA intervention effectively attenuated allergic responses in LV-KCa3.1-shRNA treated mice. LV-KCa3.1-shRNA intervention effectively suppressed KCa3.1 levels and phosphorylation of AKT in P815 cells, leading to the downregulation of tryptase, IL-6 and IL-8 levels. LV-KCa3.1-shRNA intervention effectively attenuated the allergic responses in AR and suppressed mast cell activity by inhibiting PI3K/AKT signaling pathway.

Abstract
Cell proliferation is a major underlying cause of mortality amongst patients with oral squamous cell carcinoma (OSCC); however, the underlying mechanisms have remained to be elucidated. Acylglycerol kinase (AGK) is a multisubstrate lipid kinase, which is known to be associated with the progression of various types of human cancer. The present study aimed to investigate the role of AGK in cell proliferation and cell cycle progression in OSCC. The expression levels of AGK were detected in cancerous and adjacent normal tissue samples from four patients with OSCC undergoing surgical resection, and in OSCC cell lines, using the polymerase chain reaction (PCR) and western blot analysis. The effects of AGK on the proliferation and cell cycle progression of OSCC cells were assessed using a short hairpin RNA lentivirus or expressed-plasmid transfection. In addition, the expression levels of cyclin D1 and p21, as well as cell proliferation- and cell cycle-associated proteins were detected by PCR and western blotting. The results of the present study demonstrated that the expression levels of AGK were significantly higher in the cancerous tissues and OSCC cell lines, compared with the adjacent normal tissues and control cells, respectively. Furthermore, MTT and colony formation assays, in addition to flow cytometric analysis were conducted, in order to assess the role of AGK in cell proliferation and cell cycle progression. The cell proliferation and cell cycle progression of an established OSCC cell line were demonstrated to be decreased following AGK knockdown, and enhanced by AGK overexpression in vitro. Aberrant AGK expression in OSCC was shown to be associated with cell proliferation and cell cycle progression. The results of the present study provide evidence that AGK may promote cell proliferation and cell cycle progression in OSCC.

Abstract
The aim of the present study was to investigate the expression and clinicopathological features of matrix metalloproteinase 17 (MMP17; also known as MT4-MMP) and MMP25 (also known as MT6-MMP) in gastric cancer. Immunohistochemistry and reverse transcription-quantitative polymerase chain reaction were used to detect the expression of MMP17 and MMP25 in 42 cases of gastric carcinoma and normal tissues, and 40 cases of atrophic gastritis. The expression of MMP17 in the normal gastric and atrophic gastritis tissues was significantly lower than that in the gastric cancer tissues (P<0.05). The expression of MMP25 in the gastric cancer and atrophic gastritis tissues was markedly higher compared with the normal gastric tissues (P<0.05). The expression of MMP17 and MMP25 was significantly associated with the depth of tumor invasion, lymph node metastasis and serous membrane involvement (P<0.05), but not with patient age and gender, or lesion length, site and histological grade (P>0.05). Therefore, this indicates that the expression of MMP17 and MMP25 is increased with the degree of progress of gastric carcinoma. The detection of MMP17 and MMP25 expression may have clinical value in predicting the prognosis of patients with gastric cancer.
