Abstract
Lung adenocarcinoma (LUAD) is a common histologic lung cancer with high morbidity and mortality, and most patients have distant metastases at diagnosis. RasGEF Domain Family Member 1C (RASGEF1C) could regulated Alzheimer's disease. However, its function in various cancers, including LUAD, is poorly understood. In the present study, we discovered that high expression of RASGEF1C in LUAD was associated with poorer prognosis, unfavorable histological features, and poorer pathological staging. In addition, RASGEF1C expression was an independent predictor of overall survival, disease specific survival, and progress free interval in patients with LUAD. High expression of RASGEF1C was linked to signaling pathways that are involved in the immune response and cell proliferation, according to KEGG enrichment analysis. Additionally, we verified that RASGEF1C was highly expressed in LUAD cell lines and that RASGEF1C knockdown dramatically decreased the capacity of LUAD cell lines to invade, migrate, and proliferate. Our research provides mechanistic insights into the function of RASGEF1C in the progression of LUAD and suggests that RASGEF1C is a prospective target for future therapy.
