Abstract Aim: Gastric cancer (GC) is one of the most common malignant tumors. Chrysophanol has been reported to possess antitumor effects on a variety of cancers; however, its role in GC remains unclear. This study aimed to investigate the effects of chrysophanol on the proliferation, pyroptosis, migration, and invasion of GC cells. Methods: Human GC cell lines MKN 28 and AGS cells were treated with different concentrations of chrysophanol, then cell proliferation, migration, invasion and pyroptosis were determined by CCK-8, colony-forming assay, wound healing assay, Transwell assay, and flow cytometry. Cell migration and invasion were reassessed in… More >

Abstract Introduction: Siva-1, as a pro-apoptotic protein, has been shown to induce extensive apoptosis in a number of different cell lines. In our previous study, we showed that overexpressed Siva-1 decreased the apoptosis of gastric cancer cells. So, we believe that it can also work as an anti-apoptotic protein. The present study aimed to determine the specific role of Siva-1 in anticancer drug resistance in gastric cancer in vivo and in vitro and preliminarily reveal the mechanism. Materials and Methods: A vincristine-resistant MKN-28/VCR gastric cancer cell line with stably downregulated Siva-1 was established. The effect of Siva-1 downregulation… More >

Abstract Background and Aim: Gastric cancer (GC) is one of the most common infection-related malignancies worldwide. Human Papillomavirus (HPV) and Epstein-Barr virus (EBV) are among the most important viruses affecting many people worldwide. The potential role of these viruses in gastric tissue may explain the possibility of GC, as seen in Helicobacter pylori (H. pylori). This study aimed to systematically investigate the presence of HPV and EBV in GC. Methods: According to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, this study is a systematic review based on reported cases. The keywords HPV, EBV and GC, were… More >

Abstract Gastric cancer is the fifth most commonly diagnosed cancer and the fourth leading cause of cancer death worldwide in 2020. Gastric cancer usually undergoes lymph node metastasis and implantation metastasis, but bone metastasis and bone marrow invasion are rare. However, gastric cancer patients with bone marrow invasion usually have cancer emergency, so special attention should be paid in clinical practice. Herein, we analyzed the clinical characteristics of an asian gastric cancer patient with bone marrow invasion and disseminated intravascular coagulation (DIC) in our hospital and summarized the diagnosis and treatment experience to provide a reference More >

Abstract Gastric cancer (GC) was referred to a malignant tumor of the digestive tract originating from the epithelium of gastric mucosa. Transcription factor DLX5 was verified as an oncogene in various types of tumors, while miR-376a-3p was speculated as a tumor suppressor. Based on the bioinformatics database, we hypothesized that miR-376a participated in the regulation of GC development by targeting DLX5. Compared with adjacent tissue, a significant increase of DLX5 expression was determined in GC tissues, but the expression level is significantly reduced in miR-376a. Similar expression signature of DLX5 and miR-376a was also determined between… More >

Abstract Sphingosine kinase 1 (SphK1) is an important synthetase during the synthesis of sphingosine-1-phosphate (S1P) from sphingosine (Sph). Previous studies demonstrated that arsenic trioxide (As₂O₃) could reduce the level of S1P in human gastric cancer cell line MGC-803, indicating that As₂O₃ may inhibit the activity of SphK1. In this study, the effect of As₂O₃ on the SphK1 activation pathway was investigated. Western blot and quantitative real-time PCR analysis were used to evaluate the changes in protein and mRNA levels. The multi-dimensional mass spectrometry-based shotgun lipidomics method (MDMS-SL) was used for the quantitative detection of phosphatidylserine (PS) and phosphatidic… More >

Abstract The peritoneum is the most common site of recurrence of gastric cancer (GC). Early occult peritoneal metastasis is difficult to detect by imaging examination. Stratifying the risk of peritoneal metastasis in patients with different Lauren subtypes is of great clinical value. We performed a univariate Cox regression to identify those genes with prognostic value of overall survival (OS) and peritoneal-specified disease-free survival (psDFS) from the Gene Expression Omnibus database. The candidate genes were screened by the Subpopulation Treatment Effect Pattern Plot (STEPP) method. Propensity score matching (PSM) analysis was used to reduce the interference of… More >

Abstract Gastric cancer (GC) is one of the most common cancer worldwide. Although emerging evidence indicates that autophagy-related long non-coding RNA (lncRNA) plays an important role in the progression of GC, the prognosis of GC based on autophagy is still deficient. The Cancer Genome of Atlas stomach adenocarcinoma (TCGA-STAD) dataset was downloaded and separated into a training set and a testing set randomly. Then, 24 autophagy-related lncRNAs were found strongly associated with the survival of the TCGA-STAD dataset. 11 lncRNAs were selected to build the risk score model through the least absolute shrinkage and selection operator… More >

Abstract The abnormal expression of long noncoding RNAs (lncRNAs) is frequently observed in gastric cancer (GC) and considered an important driving force in GC progression. However, little is known regarding the involvement of TMEM147-AS1 in GC. Therefore, we examined TMEM147-AS1 expression in GC and determined its prognostic value. In addition, TMEM147-AS1 expression was depleted to identify the functional changes in response to TMEM147-AS1 deficiency. Using the cancer genome atlas dataset and our own cohort, we identified a strong expression of TMEM147-AS1 in GC. Increased TMEM147-AS1 levels in GC showed a significant association with poor prognosis. TMEM147-AS1… More >

Abstract The activation of some oncogenes promote cancer cell proliferation and growth, facilitate cancer progression and metastasis by induce DNA replication stress, even genome instability. Activation of the cyclic GMP-AMP synthase (cGAS) mediates classical DNA sensing, is involved in genome instability, and is linked to various tumor development or therapy. However, the function of cGAS in gastric cancer remains elusive. In this study, the TCGA database and retrospective immunohistochemical analyses revealed substantially high cGAS expression in gastric cancer tissues and cell lines. By employing cGAS high-expression gastric cancer cell lines, including AGS and MKN45, ectopic silencing… More >
