Abstract Background Advanced gastric cancer (GC) induces diamal prognosis and high mortality. Discovery of new biomarkers or differentially expressed genes (DEGs) is serving for early diagnosis, prevention and therapautic treatmen in GC. In this study, by combining with biostatistics analysis, we aimed to verify the aberrant high expression and enhancing effects of SPP1 on GC, and to explore the probable relative post-transcriptional regulation. Methods Three datasets (GSE13911, GSE19826 and GSE27342) from NCBI GEO database were explored. SPP1 was screened out and detected in 105 real GC patients through immunohistochemistry analysis and RT-qPCR assay. The patients’ clinicopathologic features were collected and analyzed. The expression of SPP1 was examinated in three GC cell lines (MKN-45, AGS and SNU-16) . MKN-45 cell model with SPP1 depletd was constrcted through shRNA transfection. CCK8 assay, cell cycle detection and apoptosis rate calculation were conducted to evaluate the ability of cell growth. MiR-4262 was filtered out as a potential up-streaming regulator of SPP1 mRNA through bioinformatic prediction, and the dual-luciferase reporter assay was used for validation. Rescue experiment was introduced to confirm the post-transcriptional regulation. Results Thirteen DEGs increased in GC were selected, among which SPP1 was screened out for its significant over-expression in GC. SPP1 expression profile was validated in both the 105 real GC patients’ samples and three GC cell liens. High SPP1 expression was found significantly associated with the patients’ clinicopathologic features related to unideal prognosis, including tumor size, lymph node metastasis, local invasion grade and TNM stage. Depletion of SPP1 remarkably suppressed the GC cell growth. Whilst, microRNA-4262 was validated directly binding to the 3’-UTR of SPP1 mRNA in GC cells, degenerating the expression of SPP1. Conclusions SPP1 probably functions as an oncogenic gene in GC, and provides us a new biomarker in GC hopeful to promote GC prevention, diagnose and therapeutic treatment.

Long noncoding RNAs (lncRNAs) are involved in many physiological and pathological processes, such as development, aging, immunity, and cancer. Mechanistically, lncRNAs exert their functions through interaction with proteins, genomic DNA, and other RNA, leading to transcriptional and post-transcriptional regulation of gene expression, either in cis or in trans; it is often difficult to distinguish between these two regulatory mechanisms. A variety of approaches, including RNA interference, antisense oligonucleotides, CRISPR-based methods, and genetically engineered mouse models, have yielded abundant information about lncRNA functions and underlying mechanisms, albeit with many discrepancies. In this review, we elaborate on the challenges in ascribing functions to lncRNAs based on the features of lncRNAs, including the genomic location, copy number, domain structure, subcellular localization, stability, evolution, and expression pattern. We also describe a framework for the investigation of lncRNA functions and mechanisms of action. Rigorous characterization of cancer-implicated lncRNAs is critical for the identification of bona fide anticancer targets.
