Abstract Lung adenocarcinoma (LUAD) is the most common lung cancer, accounting for 19.4% of all cancer deaths. Our previous study discovered that INTS7 expression was upregulated in LUAD, while the precise mechanism by which INTS7 exerts pro-cancer effects remains unknown. In our study, shRNA was used to knockdown the expression of INTS7 in A549 cells. Cancer behaviors in vitro were determined by CCK8 and transwell assays. Xenograft mice models were constructed to detect the tumorigenesis in vivo. Immunofluorescence and toluidine blue staining were used to test the immune infiltration. Bioinformatics analysis was adopted to predict the potential signaling pathways and construct INTS7-derived genomic prognostic model. Western blot was utilized to confirm the molecular pathways. In total, downregulation of INTS7 suppressed proliferation, invasion and migration of A549 cells, as well as tumor growth. Bioinformatics and western blot analysis indicated that p38MAPK pathway participated in the regulatory mechanism of INTS7. Moreover, INTS7 expression was negatively correlated with infiltration of memory B cells and mast cells, while positively correlated with infiltration of macrophages M2. A nomogram, including INTS7-derived risk score, was used to estimate individual’s survival probability. Generally, our findings provided comprehensive understanding of the molecular mechanisms about INTS7, and targeting INTS7 may represent a potential therapy for LUAD. |
