997). Subgroup analyses found no significant associations, with one exception. The exception also depended entirely on one study. We found no significant publication bias (P=0.276). Height is not associated with increased stomach cancer risk. Epidemiologic studies of potential confounders are needed to clarify the association.Height is not associated with increased stomach cancer risk. Epidemiologic studies of potential confounders are needed to clarify the association. Carnitine palmitoyltransferase 1C (CPT1C) is a critical enzyme that catalyzes carnitinylation of fatty acids for transport into mitochondria for β-oxidation. No previous studies have been conducted to explore the prognostic and oncogenic role of CPT1C in gastric cancer (GC). Public RNA-sequencing data and micro-array data were extracted from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases respectively. Survival analysis was performed in TCGA and GSE62254 cohorts. RT-qPCR and Western blot analyses were used to determine genes expression in GC cells. Fatty acid oxidation (FAO) assay kit was used to examine cell FAO rate. The cell proliferation ability and cell cycle were tested by using CCK-8 and cell cycle assay kits. In the both TCGA and GSE62254 cohorts, high expression of CPT1C was significantly associated with poor overall (OS) (P<0.001) and disease free survival (DFS) of GC patients (P<0.001). Silence of CPT1C significantly inhibited cell FAO rate, suppressed cell proliferation and induced cell cycle arrest, while enforced CPT1C expression had the opposite effects. However, etomoxir treatment completely restricted the increase of FAO rate, cell viability and the phase of DNA synthesis caused by enhanced CPT1C expression. Selleck Panobinostat Of note, CPT1C expression was transcriptionally activated by hypoxia inducible factor-1α. High expression of CPT1C induced by hypoxia was closely associated with poor prognosis and can promote proliferation of GC cells.High expression of CPT1C induced by hypoxia was closely associated with poor prognosis and can promote proliferation of GC cells. The potential prognostic value of alternative splicing (AS) variants and regulatory splicing factors in gastric carcinogenesis is unclear. We aimed to exploit the aberrant AS signatures and splicing factors involved in gastric cancer (GC) and to determine their prognostic predictive values. We performed detailed data acquisition using the Cancer Genome Atlas project and profiled genome-wide AS signatures in a cohort of 190 patients with stomach adenocarcinoma (STAD). Prognostic prediction models and splicing correlation networks were assessed using an integrative bioinformatics analysis approach. We detected 1,308 overall survival (OS)-related AS signatures in 993 genes, most of which were favorable prognostic factors. Six splicing factors have been suggested to be dysregulated in GC, i.e., , , , , , and . Another notable finding was that most favorable prognosis AS events were positively correlated with expression of splicing factors, while a majority of poor survival prognostic AS genes were negatively associated with the expression of splicing factors. To our knowledge, the current study provided the first comprehensive profiling of global modifications in the RNA splicing to identify survival associated AS signatures of GC specific genes. Our findings contribute to a better understanding of aberrant AS signatures and splicing factors in STAD, which can potentially be used as prognostic biomarkers and therapeutic targets for GC.To our knowledge, the current study provided the first comprehensive profiling of global modifications in the RNA splicing to identify survival associated AS signatures of GC specific genes.

Fluoropyrimidine-based regimens are the cornerstone of first-line chemotherapy for metastatic gastric cancer (GC). Capecitabine or S-1 might be used as an alternative to infusional 5-fluorouracil, especially in pan-Asian. This study aimed to compare the clinical outcomes of capecitabine-based and S-1-based regimens as first-line chemotherapy in Chinese patients with unresectable or metastatic GC. We conducted a retrospective study including unresectable or metastatic GC patients treated with the capecitabine-based or S-1-based regimen as first-line chemotherapy at the First Hospital of China Medical University. Propensity score matching (PSM) analysis was performed to reduce selection bias. Overall survival (OS) outcomes were compared using the Kaplan-Meier method and log-rank test. Prognostic significance was determined using multivariate Cox regression analysis. In addition, subgroup analyses were conducted to determine the effectiveness of capecitabine-based and S-1-based regimens in clinically relevantabine-based regimen should be considered in the treatment of the GC patients with peritoneum metastasis. Pathologic complete response (pCR) after neoadjuvant chemoradiotherapy (nCRT) is associated with improved survival in patients treated for esophageal cancer. While proton beam therapy (PBT) has been demonstrated to reduce toxicities with nCRT, no data comparing pCR rates between modalities exist to date. We investigated pCR rates in patients with distal esophageal/GEJ adenocarcinomas undergoing trimodality therapy with nCRT-PBT or photon-based nCRT with the hypothesis that pathologic responses with PBT would be at least as high as with photon therapy. A single-institutional review of patients with distal esophageal adenocarcinoma treated with trimodality therapy from 2015-2018 using PBT was completed. PBT patients were matched 12 to patients treated with photons. Chi square and two-sample -tests were utilized to compare characteristics, and the Kaplan Meier method was used to estimate oncologic endpoints. Eighteen consecutive PBT patients were identified and compared to 36 photon patients. All patientnocarcinoma yields pCR rates comparable to photon radiation and historical controls. Pathologic responses and oncologic outcomes in this study did not differ significantly between modalities despite PBT patients having higher AJCC stages and nodal disease burdens.The use of PBT in trimodality therapy for distal esophageal adenocarcinoma yields pCR rates comparable to photon radiation and historical controls.
