Liu B, Li K, Ma R, Zhang Q. Two web-based dynamic prediction models for the diagnosis and prognosis of gastric cancer with bone metastases: evidence from the SEER database. Front Endocrinol (Lausanne) 2023; 14:1136089. [PMID: 37293503 PMCID: PMC10244808 DOI: 10.3389/fendo.2023.1136089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Accepted: 04/03/2023] [Indexed: 06/10/2023] Open
Abstract
Purpose Our aim was to identify the clinical characteristics and develop and validate diagnostic and prognostic web-based dynamic prediction models for gastric cancer (GC) with bone metastasis (BM) using the SEER database. Method Our study retrospectively analyzed and extracted the clinical data of patients aged 18-85 years who were diagnosed with gastric cancer between 2010 and 2015 in the SEER database. We randomly divided all patients into a training set and a validation set according to the ratio of 7 to 3. Independent factors were identified using logistic regression and Cox regression analyses. Furthermore, we developed and validated two web-based clinical prediction models. We evaluated the prediction models using the C-index, ROC, calibration curve, and DCA. Result A total of 23,156 patients with gastric cancer were included in this study, of whom 975 developed bone metastases. Age, site, grade, T stage, N stage, brain metastasis, liver metastasis, and lung metastasis were identified as independent risk factors for the development of BM in GC patients. T stage, surgery, and chemotherapy were identified as independent prognostic factors for GC with BM. The AUCs of the diagnostic nomogram were 0.79 and 0.81 in the training and test sets, respectively. The AUCs of the prognostic nomogram at 6, 9, and 12 months were 0.93, 0.86, 0.78, and 0.65, 0.69, 0.70 in the training and test sets, respectively. The calibration curve and DCA showed good performance of the nomogram. Conclusions We established two web-based dynamic prediction models in our study. It could be used to predict the risk score and overall survival time of developing bone metastasis in patients with gastric cancer. In addition, we also hope that these two web-based applications will help physicians comprehensively manage gastric cancer patients with bone metastases.

Li Z, Zheng H, Zhao Z, Chen G, Wang Z, Amin B, Zhang N. Identification of optimal primary tumor resection candidates for metastatic gastric cancer: Nomograms based on propensity score matching. Cancer Med 2023. [PMID: 37096953 DOI: 10.1002/cam4.5983] [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: 09/21/2022] [Revised: 03/28/2023] [Accepted: 04/08/2023] [Indexed: 04/26/2023] Open
Abstract
BACKGROUND This study sought to develop and validate nomograms for screening patients with metastatic gastric cancer (mGC) who are candidates for primary tumor resection (PTR) and evaluating the prognosis of mGC patients after PTR. METHODS From 2010 to 2016, we screened mGC patients with complete data from the Surveillance, Epidemiology, and End Results (SEER) database. Depending on whether or not PTR was performed, we categorized patients into surgery and non-surgery groups. A 1:1 propensity score matching (PSM) analysis was used to balance the characteristics of the two groups. The endpoints were overall survival (OS) and cancer-specific survival (CSS). Two predictive nomograms were developed using logistic regression to assess the likelihood of benefit. Two additional prognostic nomograms were developed to assess prognosis in mGC patients after PTR by Cox regression. Finally, nomograms were evaluated using a variety of methodologies. RESULTS Our study included 3594 mGC patients who met the criteria. PTR was associated with improved OS and CSS time (median OS time after PSM: 15 vs. 7 months, P < 0.05; median CSS time after PSM: 17 vs. 7 months, P < 0.05). The OS-related predictive nomogram, including age, histologic type, grade, T stage, and chemotherapy, was developed. Moreover, the CSS-related predictive nomogram, including age, histologic type, grade, and chemotherapy, was developed. Sex, histologic type, grade, T stage, N stage, and chemotherapy were found to be correlated with OS. Furthermore, the CSS correlated with histologic type, grade, T stage, N stage, and chemotherapy. Both predictive and prognostic nomograms were found to be valuable and reliable after different types of validation. CONCLUSION Predictive nomograms were developed and validated for identifying the optimal PTR mGC candidates. Prognostic nomograms were developed and validated for assessing the prognosis of mGC patients after PTR.

Comprehensive Molecular Analyses of Notch Pathway-Related Genes to Predict Prognosis and Immunotherapy Response in Patients with Gastric Cancer. JOURNAL OF ONCOLOGY 2023; 2023:2205083. [PMID: 36733672 PMCID: PMC9889149 DOI: 10.1155/2023/2205083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 11/06/2022] [Accepted: 11/24/2022] [Indexed: 01/26/2023]
Abstract
Gastric cancer (GC) is a highly molecular heterogeneous tumor with unfavorable outcomes. The Notch signaling pathway is an important regulator of immune cell differentiation and has been associated with autoimmune disorders, the development of tumors, and immunomodulation caused by tumors. In this study, by developing a gene signature based on genes relevant to the Notch pathway, we could improve our ability to predict the outcome of patients with GC. From the TCGA database, RNA sequencing data of GC tumors and associated normal tissues were obtained. Microarray data were collected from GEO datasets. The Molecular Signature Database (MSigDB) was accessed in order to retrieve sets of human Notch pathway-related genes (NPRGs). The LASSO analysis performed on the TCGA cohort was used to generate a multigene signature based on prognostic NPRGs. In order to validate the gene signature, the GEO cohort was utilized. Using the CIBERSORT method, we were able to determine the amounts of immune cell infiltration in the GC. In this study, a total of 21 differentially expressed NPRGs were obtained between GC specimens and nontumor specimens. The construction of a prognostic prediction model for patients with GC involved the identification and selection of three different NPRGs. According to the appropriate cutoff value, the patients with GC were divided into two groups: those with a low risk and those with a high risk. The time-dependent ROC curves demonstrated that the new model had satisfactory performance when it came to prognostic prediction. Multivariate assays confirmed that the risk score was an independent marker that may be used to predict the outcome of GC. In addition, the generated nomogram demonstrated a high level of predictive usefulness. Moreover, the scores of immunological infiltration of the majority of immune cells were distinctly different between the two groups, and the low-risk group responded to immunotherapy in a significantly greater degree. According to the results of a functional enrichment study of candidate genes, there are multiple pathways and processes associated with cancer. Taken together, a new gene model associated with the Notch pathway may be utilized for the purpose of predicting the prognosis of GC. One potential method of treatment for GC is to focus on NPRGs.

The prognostic impact of the lymphocyte-to-C-reactive protein ratio in patients with unresectable or recurrent advanced gastric cancer treated with first- and second-line treatment. Surg Today 2023:10.1007/s00595-022-02638-w.

Abstract
PURPOSE The goal of this study was to determine which markers are the most useful as first- and second-line pre-treatment markers in patients with unresectable or recurrent gastric cancer (URGC). METHODS This study included 101 URGC patients who were treated with first- and second-line chemotherapy. Several prognostic scores based on nutrition and inflammation were analyzed using a receiver operating characteristic (ROC) analysis to determine the most useful prognostic marker. RESULTS The lymphocyte-to-C-reactive protein ratio (LCR) had the highest area under the curve for both first- and second-line chemotherapy, according to an ROC analysis. An ROC analysis was used to determine the optimal LCR cut-off for the median survival time before first- and second-line chemotherapy, and patients were divided into high- and low-LCR groups. Patients with a high LCR had a significantly longer survival than those with a low LCR before first- and second-line chemotherapy (p = 0.004, p < 0.001, respectively). A low LCR before both first- and second-line chemotherapy was an independent poor prognostic factor in a multivariate analysis. CONCLUSIONS URGC patients with a low LCR before both first- and second-line chemotherapy had a significantly worse prognosis than those with a high LCR in this study. Nutritional intervention during chemotherapy induction may lead to a better prognosis.

Abstract
Gastric cancer is one of the most common malignant tumors, which remains as an obstacle to human health. Nowadays, targeted nanoparticles to gastric tumor tissues, provide new strategy for improved therapy but still remain challenging. The major hurdle of targeted therapeutic nanoparticles comes from the limited enrichment and poor selectivity of therapeutic agents in in situ tumor. Herein, a pH-sensitive targeted nano platform coloaded As2 O3 and human epidermal growth factor receptor-2 (HER2)-siRNA (AH RNPs) is developed to achieve targeting therapy in orthotopic gastric carcinoma. AH RNPs can effectively prevent the degradation of siRNA and overcome the poor solubility of As2 O3 . In vitro studies show that AH RNPs could achieve synergistic inhibition of growth and metastasis on SGC7901 cells. Surprisingly, AH RNPs not only target gastric subcutaneous tumor, but also target in situ tumor, and express loaded genes in in situ tumor. Moreover, AH RNPs show excellent antitumor effect in orthotopic gastric tumor model and the anticancer mechanism is related about inhibiting the activation of ERK signal and downregulating the expression of cxc chemokine receptor 4 (CXCR4), HER2, MMP2, and MMP9 protein. This study provides a multi-functional vector for precise targeting therapy of gastric cancer, which may serve as a potential clinical application for future gastric cancer.

Histone Methyltransferase SETD1A Induces Epithelial-Mesenchymal Transition to Promote Invasion and Metastasis Through Epigenetic Reprogramming of Snail in Gastric Cancer. Front Cell Dev Biol 2021; 9:657888. [PMID: 34164392 PMCID: PMC8215546 DOI: 10.3389/fcell.2021.657888] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2021] [Accepted: 05/03/2021] [Indexed: 01/15/2023] Open
Abstract
Aberrant epigenetic modification induces oncogene expression and promotes cancer development. The histone lysine methyltransferase SETD1A, which specifically methylates histone 3 lysine 4 (H3K4), is involved in tumor growth and metastasis, and its ectopic expression has been detected in aggressive malignancies. Our previous study reported that SETD1A promotes gastric cancer (GC) proliferation and tumorigenesis. However, the function and molecular mechanisms of SETD1A in GC metastasis remain to be elucidated. In this study, we found that overexpression of SETD1A promoted GC migration and invasion, whereas knockdown of SETD1A suppressed GC migration and invasion in vitro. Moreover, knockdown of SETD1A suppressed GC epithelial-mesenchymal transition (EMT) by increasing the expression of epithelial marker E-cadherin and decreasing the expression of mesenchymal markers, including N-cadherin, Fibronectin, Vimentin, and α-smooth muscle actin (α-SMA). Mechanistically, knockdown of SETD1A reduced the EMT key transcriptional factor snail expression. SETD1A was recruited to the promoter of snail, where SETD1A could methylate H3K4. However, knockdown of SETD1A decreased the methylation of H3K4 on the snail promoter. Furthermore, SETD1A could be a coactivator of snail to induce EMT gene expression. Rescue of snail restored SETD1A knockdown-induced GC migration and invasion inhibition. In addition, knockdown of SETD1A suppressed GC metastasis in vivo. In summary, our data revealed that SETD1A mediated the EMT process and induced metastasis through epigenetic reprogramming of snail.

Cancer Manag Res 2021; 13:899-912. [PMID: 33564265 PMCID: PMC7867499 DOI: 10.2147/cmar.s287775] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Accepted: 12/24/2020] [Indexed: 12/15/2022] Open
Abstract
Background Linc-ROR is a long non-coding RNA, that is found aberrantly expressed in various human cancers. We aim here to unveil the role of Linc-ROR in gastric cancer (GC) progression. Methods qPCR was used to determine gene expression. Cell viability was measured by CCK-8 assay. Transwell assays were performed to evaluate the GC cells’ migratory and invasive abilities. Xenograft mouse model was conducted to measure tumor growth. Results We found that Linc-ROR were overexpressed in GC tissues compared to the adjacent tissues. High Linc-ROR predicts poor prognosis of GC patients. The prediction of bioinformatics online revealed that Linc-ROR could bind to miR-212-3p. Further, dual-luciferase reporter assay confirmed a direct interaction between Linc-ROR and miR-212-3p. Overexpression of miR-212-3p facilitated GC cells’ migration and invasion, while the silencing of miR-212-3p attenuated GC cell migratory and invasive abilities. Moreover, Linc-ROR knockdown significantly suppressed the proliferation, migration, and invasion of GC cells, whereas miR-212-3p antagomir partially reversed Linc-ROR knockdown-induced phenotypes. Fibroblast growth factor 7 (FGF7), a downstream molecule of miR-212-3p, was overexpressed in GC cells. The recovery of FGF7 expression partially reversed the phenotypes caused by Linc-ROR silencing. Mechanistically, silencing of Linc-ROR contributed to the downregulation of CDK4, CDK6, Cyclin D1, N-Cadherin, Vimentin, MMP-9, MMP-2, but caused the upregulation of P21, P27, E-Cadherin, CK-19 in MGC-803 cells; however, FGF7 treatment could reverse the results induced by Linc-ROR silencing. Results in vivo further suggested that Linc-ROR knockdown repressed GC tumor growth, where the expression of miR-212-3p was up-regulated and FGF7 expression was downregulated in tumor tissues of mice. Conclusion These findings indicated that Linc-ROR/miR-212-3p/FGF7 axis played an important role in gastric cancer progression. Linc-ROR expression level was associated with the prognosis of GC patients.

SATB1-Mediated Upregulation of the Oncogenic Receptor Tyrosine Kinase HER3 Antagonizes MET Inhibition in Gastric Cancer Cells. Int J Mol Sci 2020; 22:ijms22010082.

Abstract
MET-amplified gastric cancer cells are extremely sensitive to MET inhibition in vitro, whereas clinical efficacy of MET inhibitors is disappointing. The compensatory activation of other oncogenic growth factor receptors may serve as an underlying mechanism of resistance. In this study, we analyzed the role of HER receptors, in particular HER3 and its ligand heregulin, in this respect. This also included the chromatin-organizer protein SATB1, as an established regulator of HER expression in other tumor entities. In a panel of MET-amplified gastric carcinoma cell lines, cell growth under anchorage-dependent and independent conditions was studied upon inhibitor treatment or siRNA-mediated knockdown. Expression analyses were performed using RT-qPCR, FACS, and immunoblots. Signal transduction was monitored via antibody arrays and immunoblots. As expected, MET inhibition led to a growth arrest and inhibition of MAPK signaling. Strikingly, however, this was accompanied by a rapid and profound upregulation of the oncogenic receptor HER3. This finding was determined as functionally relevant, since HER3 activation by HRG led to partial MET inhibitor resistance, and MAPK/Akt signaling was even found enhanced upon HRG+MET inhibitor treatment compared to HRG alone. SATB1 was identified as mediator of HER3 upregulation. Concomitantly, SATB1 knockdown prevented upregulation of HER3, thus abrogating the HRG-promoted rescue from MET inhibition. Taken together, our results introduce the combined HER3/MET inhibition as strategy to overcome resistance towards MET inhibitors.

Abstract
Background Although the aberrant expression and function of most Ca2+-permeable channels are known to promote gastrointestinal tumors, the association between transient receptor potential vanilloid receptor 1 (TRPV1) channels and gastric cancer (GC) has not yet been explored. Herein, we sought to determine the role of TRPV1 channels in the development of GC and to elucidate the underlying molecular mechanisms involved therein. Methods Immunohistochemistry, qPCR, Western blot, immunofluorescence assays were used to detect the mRNA and protein expression of TRPV1 in GC cells and tissues, and the clinical significance of TRPV1 in GC was also studied by clinicopathologic analysis. CCK8, colony formation, flow cytometry assays were used to detect the proliferation and survival of GC cells, while transwell assay was used to detect migration and invasion of GC cells in vitro. Tumor xenograft and peritoneal dissemination assays in nude mice were used to examine the role of TRPV1 in GC development in vivo. Results TRPV1 expression was significantly downregulated in human primary GC tissues compared to their adjacent tissues. The decreased expression of TRPV1 proteins in GC tissues was positively correlated with tumor size, histological grade, lymphatic metastasis, clinical stage, and was strongly correlated with poor prognosis of GC patients. Moreover, the expression of TRPV1 was closely correlated with Ki67, VEGFR, and E-cadherin, all of which are the well-known cancer markers for proliferation and metastasis. TRPV1 proteins were predominately expressed on the plasma membrane in several GC cell lines. TRPV1 overexpression blocked cell cycle at G1 phase to inhibit GC cell proliferation and attenuated migration and invasion of GC cells in vitro, but TRPV1 knockdown increased these parameters. TRPV1 significantly reduced gastric tumor size, number and peritoneal dissemination in vivo. Mechanistically, TRPV1 overexpression in GC cells increased [Ca2+]i, activated CaMKKβ and AMPK phosphorylation, and decreased expression of cyclin D1 and MMP2, while TRPV1 knockdown induced the opposite effects. Conclusions TRPV1 uniquely suppresses GC development through a novel Ca2+/CaMKKβ/AMPK pathway and its downregulation is correlated with poor survival of human GC patients. Thus, TRPV1 upregulation and its downstream signaling may represent a promising target for GC prevention and therapy.

Abstract
BACKGROUND Recurrence is the leading cause of treatment failure and death in patients with gastric cancer (GC). However, the mechanism underlying GC recurrence remains unclear, and prognostic markers are still lacking. METHODS We analyzed DNA methylation profiles in gastric cancer cases with shorter survival (<1 year) or longer survival (> 3 years), and identified candidate genes associated with GC recurrence. Then, the biological effects of these genes on gastric cancer were studied. RESULTS A novel gene, magnesium-dependent phosphatase 1 (mdp1), was identified as a candidate gene whose DNA methylation was higher in GC samples from patients with shorter survival and lower in patients with longer survival. MDP1 protein was highly expressed in GC tissues with longer survival time, and also had a tendency to be expressed in highly differentiated GC samples. Forced expression of MDP1 in GC cell line BGC-823 inhibited cell proliferation, whereas the knockdown of MDP1 protein promoted cell growth. Overexpression of MDP1 in BGC-823 cells also enhanced cell senescence and apoptosis. Cytoplasmic kinase protein c-Jun N-terminal kinase (JNK) and signal transducer and activator of transcription 3 (Stat3) were found to mediate the biological function of MDP1. CONCLUSION These results suggest that MDP1 protein suppresses the survival of gastric cancer cells and loss of MDP expression may benefit the recurrence of gastric cancer.

Abstract
BACKGROUND The present study aimed to investigated the expression pattern of long noncoding RNA LINC00858 (LINC00858) in gastric cancer (GC) patients and its feasibility as a new prognostic biomarker. METHODS We examined LINC00858 expression in GC tissues and matched normal tissues from 189 patients using a quantitative reverse transcription-polymerase chain reaction. The correlations of LINC00858 levels in GC patients with clinicopathologic features were analyzed using a chi-squared test. The influence of LINC00858 on the overall survival rate of GC patients was precisely calculated using Kaplan-Meier methods (log rank tests). Multivariate Cox regression assays were carried out for the identification of the independent risk factors for GC. RESULTS We observed that LINC00858 was distinctly up-regulated in GC tissues compared to adjacent non-tumor specimens (p < 0.01). Higher expression of LINC00858 in GC was found to be associated with TNM stage (p = 0.003) and lymphatic metastasis (p = 0.007). Using Kaplan-Meier assays, we found that patients with high expression levels of LINC00858 had a distinctly poor overall survival and disease-free survival compared to those with low expression levels of LINC00858 (p = 0.0102). Multivariate analyses confirmed that LINC00858 (p < 0.05) was an independent prognosis factor for GC patients. CONCLUSIONS The data obtained in our study indicate that LINC00858 may be used as a novel prognostic indicator in GC patients.

Abstract
Xanthohumol (Xn), a prenylated flavonoid isolated from Hops (Humulus lupulus L.), has demonstrated potent anticancer activity in multiple types of cancer. However, the effect of Xn on gastric cancer (GC) remains unknown. The aim of the present study was to investigate the effect of Xn on GC cell proliferation, apoptosis and metastasis. It was observed that Xn decreased the viability of GC cells, with very low or no toxicity to normal gastric epithelial cells GES‑1 at a concentration of 1‑100 µM. The proliferation of AGS cells was inhibited by Xn, as indicated by the decreased number of EdU‑positive cells. Xn treatment increased the number of apoptotic cells, downregulated the expression of Bcl‑2 and upregulated the expression of Bax, suggesting induction of apoptosis. The results from the wound healing and Transwell assays indicated that Xn suppressed AGS cell metastasis. Moreover, Xn induced reactive oxygen species (ROS) overproduction and inhibited nuclear factor (NF)‑κB signaling in AGS cells, which was reversed by the ROS inhibitor N‑acetylcysteine (NAC). NAC suppressed the effect of Xn on the proliferation, apoptosis and metastasis of AGS cells. Taken together, these results suggest that Xn exerts anticancer effects against GC via induction of ROS production and subsequent inhibition of NF‑κB signaling. Therefore, Xn may be a promising candidate treatment against GC progression.

Abstract
The incidence and mortality of gastric cancer is steadily increasing annually around the world, which required further investigation about alternative therapy strategies. Melatonin, an indoleamine synthesized in the pineal gland, has shown dramatic anticancer effect in several cancers, however, the function of melatonin in gastric cancer needs to be characterized. In this study, we found that melatonin inhibited the growth and induced apoptosis of gastric cancer cells. microRNAs (miRNAs) have been attractive targets for many anticancer drugs. To explore the underlying molecular mechanism by which melatonin attenuated the growth of cancer cells, miRNA microarray analysis was performed to screen the miRNAs, which significantly altered after melatonin treatment. The result showed that melatonin administration enhanced the expression of miR-16-5p. Further molecular mechanism research revealed that miR-16-5p targeted Smad3 and consequently negatively regulated the abundance of Smad3. Consistently, melatonin exposure decreased the level of Smad3 and overexpression of Smad3 attenuated the inhibitory effect of melatonin in gastric cancer cells. These results uncovered the anticancer effect of melatonin and highlighted the critical roles of miR-16-5p-Smad3 pathway in melatonin-induced growth defects of gastric cancers.

Abstract
Chemoresistance limits treatment efficacy in gastric cancer and doxorubicin resistance is common in gastric cancer cells. Dual specificity phosphatase 4 (DUSP4) has been associated with tumor progression. This study aimed to investigate the mechanism of DUSP4 regulating doxorubicin resistance in gastric cancer cells. Cell Counting Kit-8 (CCK-8) and 5-ethynyl-2'-deoxyuridine (EdU) incorporation assay were used to measure cell viability and proliferation in gastric cancer cells treated with doxorubicin. The expression of DUSP4, E-cadherin and Vimentin protein was detected by Western blotting. Overexpression of DUSP4 was more resistant to doxorubicin in gastric cancer cells. Knockdown of DUSP4 increased the sensitivity of gastric cancer cells to doxorubicin. Moreover, up-regulation of DUSP4 promoted the Epithelial-Mesenchymal Transition (EMT) in gastric cancer cells, but blocking the EMT using a Twist siRNA increased the sensitivity of gastric cancer cells to doxorubicin and confirmed the EMT was involved in DUSP4-mediated doxorubicin resistance. These findings demonstrated that DUSP4 could enhance doxorubicin resistance by promoting EMT in gastric cancer cells.
