Abstract
BACKGROUND Asporin (ASPN) has been identified as a player in tumorigenesis, but its precise roles and modulatory function are largely unknown. METHODS In the present study, ASPN expression was first explored, followed by a prognostic evaluation of ASPN and a comprehensive investigation of the connections between ASPN and immunomodulation, immune cell infiltration and potential compounds on a pancancer level. Finally, ASPN expression was validated in bladder urothelial carcinoma (BLCA) tissues, and the potential function of ASPN, including its effects on migration and invasion capabilities, was investigated in tumor cells. RESULTS The expression of ASPN exhibited significant variation across cancers and was found to be associated with patient prognosis. In addition, the expression level of APSN was markedly correlated with the abundances of infiltrating immune cells and cancer-associated fibroblasts and the expression levels of immunomodulatory genes based on the results of pancancer analysis. Metastasis and immune-associated signaling pathways were identified in enrichment analysis based on ASPN expression. Finally, we confirmed that ASPN expression increased with the degree of malignancy in BLCA tissues and cell lines and that low expression of ASPN hindered the migration and invasion of cells. CONCLUSIONS ASPN has the potential to be a biomarker of cancer prognosis and a therapeutic target, and it also has predictive capability for the progression of BLCA.

Abstract
The molecular genetics of gastric carcinoma (GC) dictates their biology and clinical behavior. The two morphologically distinct types of gastric carcinoma by Lauren classification, i.e., intestinal and diffuse cell types, have a significant difference in clinical outcome. These two types of GC have different molecular pathogenetic pathways with unique genetic alterations. In addition to environmental and other etiologies, intestinal type GC is associated with Helicobacter pylori (H. pylori) infection and involves a multistep molecular pathway driving the normal epithelium to intestinal metaplasia, dysplasia, and malignant transformation by chromosomal and/or microsatellite instability (MSI), mutation of tumor suppressor genes, and loss of heterozygosity among others. Diffuse type shows no clear causal relationship with H. pylori infection, but is commonly associated with deficiency of cell-cell adhesion due to mutation of the E-cadherin gene (CDH1), and a manifestation of the hereditary gastric cancer syndrome. Thus, detection of CDH1 mutation or loss of expression of E-cadherin may aid in early diagnosis or screening of diffuse type GC. Detection of certain genetic markers, for example, MSI and matrix metalloproteinases, may provide prognostic information, particularly for intestinal type. The common genetic alterations may offer therapeutic targets for treatment of GC. Polymorphisms in Thymidylate synthase to metabolize 5-fluorouracil, glutathione S-transferase for degradation of Cisplatin, and amplification/overexpression of human epidermal growth factor receptor 2 targeted by monoclonal antibody Trastuzumab, are a few examples. P13K/Akt/mTOR pathway, c-Met pathways, epidermal growth factor receptor, insulin-like growth factor receptor, vascular endothelial growth factor receptor fibroblast growth factor receptor, and micro RNAs are several potential therapeutic biomarkers for GC under investigation.
