Abstract
Integrin alpha L (ITGAL), a member of the integrin family, is associated with carcinogenesis and immune regulation. However, the biological functions of ITGAL in lung adenocarcinoma (LUAD) remain poorly understood. In this study, we utilized the TCGA dataset to analyse ITGAL mRNA expression in LUAD and examined its correlation with clinical prognosis. Three-dimensional (3D) Matrigel culture, 5-bromodeoxyuridine (BrdU) ELISA, wound-healing migration and cell adherence assays were used to demonstrate the potential role of ITGAL in LUAD progression. Additionally, we analysed single-cell sequencing data of LUAD to determine the expression and biological function of ITGAL. Our research revealed that the expression of ITGAL in LUAD samples is an independent predictor of prognosis. Patients with high expression of ITGAL had significantly better overall survival (OS), progression-free survival (PFS) and disease-specific survival (DSS) compared to the low-expression group. Meanwhile, the expression of ITGAL suppressed malignant progression in LUAD cells. Functional enrichment analyses showed that ITGAL was significantly correlated with cell immune response and immune checkpoint, consistent with the analysis of single-cell sequencing in paired samples of normal and tumour. Furthermore, we confirmed that ITGAL expression affect the tumour microenvironment (TME) through regulation of the expression of cytokines in NK cells of LUAD. In summary, ITGAL is a prognostic biomarker for LUAD patients, and it repressed malignant progression in LUAD cells. Moreover, ITGAL expression also enhanced the effect of immunotherapy and may be an important target in LUAD therapy.

Li Y, Wang L, Jia X, Yang Y, Qiu Z. Bioinformatic analysis reveals the clinical value of SASH3 in survival prognosis and immune infiltration of acute myelocytic leukemia (AML). Am J Transl Res 2023; 15:6858-6866. [PMID: 38186980 PMCID: PMC10767538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2023] [Accepted: 11/21/2023] [Indexed: 01/09/2024]
Abstract
Acute myeloid leukemia (AML), a malignant clonal disease, is the most prevalent form of leukemia, and it is associated with a poor prognosis and unfavorable treatment outcomes in both pediatric and adult populations. Accordingly, enhancing anti-tumor responses using immunomodulators is a promising therapeutic strategy and a new avenue for treating AML. In this study, we used publicly available data from The Cancer Genome Atlas and Genotype-Tissue Expression databases to investigate the correlation between SAM and SH3 domain-containing 3 (SASH3) and AML, and we performed Cox regression and Kaplan-Meier analyses to assess the clinical characteristics associated with overall survival among patients with AML. Additionally, we analyzed the relationship between immune infiltration and SASH3. Compared with that in the normal group, patients with AML were characterized by significantly higher levels of SASH3 expression (P = 3.05e-34), which was strongly associated with survival outcomes. We observed a significant correlation between SASH3 expression and the expression of cancer-related genes (HCK, SYK, FYN, ITGB2, PIK3CD, FGR, PIK3R5, VAV1, LCP2, and GRB2) and pathways. Our findings in this study indicate that SASH3 plays a key role in AML development and survival outcomes and in the regulation of small GTPase-mediated signal transduction and immune-related pathways. Accordingly, targeting SASH3 may offer a promising approach for the treatment of AML and may potentially influence the progression of other cancers via multiple immune pathways.
