The nomogram based on INPS may serve as a simple and potential model in risk stratification and guiding treatment strategies in clinical practice. Preoperative INPS was an independent prognostic factor of stage III GC patients with radical surgery followed by adjuvant chemotherapy. The nomogram based on INPS may serve as a simple and potential model in risk stratification and guiding treatment strategies in clinical practice. Gastric cancer (GC) is a malignancy with high morbidity and mortality rates worldwide. SNHG12 is a long noncoding RNA (lncRNA) commonly involved many types of cancers in the contexts of tumorigenesis, migration and drug resistance. Nevertheless, its role in GC proliferation is poorly understood. Bioinformatics and qRT-PCR assays were used to analyze the expression of SNHG12 in GC tissues and cells. and experiments were conducted to detect the role of SNHG12 in GC development. qRT-PCR, PCR, western blotting (WB), RNA binding protein immunoprecipitation (RIP), immunoprecipitation (IP), immunohistochemistry (IHC), fluorescence hybridization (FISH) and hybridization (ISH) were performed to investigate the underlying mechanisms by which SNHG12 promotes GC proliferation. SNHG12 was highly expressed in GC cells and tissues, and predicted poor survival. and assays showed that SNHG12 knockdown inhibited GC proliferation, while SNHG12 overexpression promoted GC proliferation. Further experiments confirmed that SNHG12 was mainly located in the cytoplasm and bound to HuR. Bioinformatics analysis predicted that YWHAZ was the common target of SNHG12 and HuR, and that the "SNHG12-HuR" complex enhanced the stability of YWHAZ mRNA. Furthermore, YWHAZ, which was highly expressed in GC, predicted poor survival and promoted GC proliferation by phosphorylating AKT. Rescue assays verified that SNHG12 promoted GC proliferation by activating the AKT/GSK-3β pathway. SNHG12 binds to
