Clinical samples were analyzed for SCYL1 expression and its correlation with patient prognosis. In vitro and in vivo experiments were conducted to assess SCYL1's function in GC cell migration, invasion, and autophagy.  \nResults SCYL1 showed an increased expression in GC tissues, which correlated with a negative prognosis. In vitro experiments demonstrated that SCYL1 promotes GC cell migration and invasion and inhibits autophagy. GSEA indicated an inverse relationship between SCYL1 and autophagy, while a direct relationship was observed with the mTORC1 signaling pathway. Knockdown of SCYL1 enhanced autophagy, while activation of mTORC1 reversed this effect.  \nConclusions SCYL1 is a significant contributor to GC progression, promoting metastasis by activating the mTORC1 signaling pathway and inhibiting autophagy. These findings suggest SCYL1 as a potential therapeutic target for GC treatment.  \nKeywords SCYL1 · Gastric cancer · Metastasis · mTORC1 · Autophagy  \nIntroduction  \nGastric cancer (GC) ranks among the most common and deadliest types of cancer worldwide. Global cancer statistics indicate that the incidence and mortality rates of GC are significantly high, contributing to the global cancer burden  \nZihao Zhao, Jinlong Liu and Xian Gao contributed equally to this work.  \n* Wanjiang Xue [xuewanjiang@ntu.edu.cn](xuewanjiang@ntu.edu.cn)  \nWeijie Zang  \n[zangweijie@stmail.ntu.edu.cn](zangweijie@stmail.ntu.edu.cn)  \n1 Department of Gastrointestinal Surgery, Affiliated Hospital of Nantong University, Medical School of Nantong University, Nantong 226001, China  \n2 Research Center of Clinical Medicine, Affiliated Hospital of Nantong University, Nantong 226001, China  \n3 Nantong Key Laboratory of Gastrointestinal Oncology, Nantong 226001, China  \n4 Qidong People’s Hospital, Nantong 226001, China  \n(Sung et al. 2020) . Even with the progress in early detection and therapeutic approaches in recent years, the five-year survival rate for GC patients is still under 30%, with some regions reporting even lower percentages. Postoperative recurrence is a major cause of poor prognosis in GC patients, with approximately 60% experiencing varying degrees of recurrence after surgery (Thrift and El-Serag 2020) . This high recurrence rate underscores the urgent need for a deeper understanding of the biology of GC metastasis and the development of new therapeutic strategies to improve long-term patient survival.  \nThe SCY1-like (SCYL) family comprises a group of proteins associated with intracellular transport, cell cycle regulation, and signal transduction (Yan et al. 2010). This family includes at least three known members: SCYL1, SCYL2, and SCYL3, all of which possess kinase domains and HEAT repeat sequences (Pelletier 2016) . While the specific roles of their kinase activities in biological functions are not fully understood, they play significant roles in various intracellular processes. The association of the SCYL family with cancer metastasis has been confirmed in multiple studies. For instance, SCYL3 promotes the metastasis of hepatocellular  \ncarcinoma by physically binding and regulating the stability and transactivating acti","cbCaiareJCNAFVQw","https://ap.wps.com/l/cbCaiareJCNAFVQw","pdf",11551838,15,"English","# Abstract\n## Background\n## Methods\n## Results\n## Conclusions\n# Introduction\n## Background on GC and metastasis\n## SCYL family and cancer links\n## Autophagy and mTORC1 regulation\n# Materials and methods","[{\"question\":\"What was the main research question about SCYL1 in gastric cancer?\",\"answer\":\"The study asked whether SCYL1 contributes to gastric cancer progression and clarified how it influences metastasis through autophagy and the mTORC1 signaling pathway.\"},{\"question\":\"How were SCYL1’s role and clinical relevance evaluated?\",\"answer\":\"SCYL1 function in GC was assessed using public databases (Deepmap, TCGA, GEO).
