The Therapeutic Potential of ADAMTS8 in Lung Adenocarcinoma without Targetable Therapy.

ABSTRACT: Lung cancer is well known for its high mortality worldwide. The treatment for advanced lung cancer needs more attention to improve its survival time. A disintegrin and metallopeptidase with thrombospondin motifs 8 (ADAMTS8) has been linked to several cancer types. However, its role in lung cancer is worthy of deep investigation to promote novel drug development. This study took advantage of RNA-seq and bioinformatics to verify the role that ADAMTS8 plays in lung cancer. The functional assays suggested that ADAMTS8 mediates invasion and metastasis when expressed at a low level, contributing to poor overall survival (OS). The expression of ADAMTS8 was under the regulation of GATA Binding Protein 1 (GATA1) and executed its pathologic role through Thrombospondin Type 1 Domain Containing 1 (THSD1) and ADAMTS Like 2 (ADAMTSL2). To define the impact of ADAMTS8 in the lung cancer treatment strategy, this study further grouped lung cancer patients in the TCGA database into mutated epidermal growth factor receptor (EGFR)/wild-type EGFR and programmed death ligand 1 (PD-L1) high/low groups. Importantly, the expression of ADAMTS8 was correlated positively with the recruitment of anticancer NKT cells and negatively with the infiltration of immunosuppressive Treg and exhausted T cells. The results indicated that lung cancer patients with higher ADAMTS8 levels among wild-type EGFR or low PD-L1 groups survive longer than those with lower levels do. This study indicates that ADAMTS8 might be a treatment option for patients with lung adenocarcinoma who lack efficient targeted or immunotherapies.

Project description:BackgroundThe current study aimed to investigate the interrelation between P2RY14 and the prognosis of patients suffering from lung adenocarcinoma (LUAD) following surgery.MethodsThe differentially expressed gene (DEG) P2RY14 was screened by the Gene Expression Omnibus (GEO), The Cancer Genome Atlas (TCGA), and Immunology Database and Analysis Portal (ImmPort) databases. The relationship between P2RY14 and clinical data of LUAD was analyzed in TCGA and Kaplan-Meier (KM)-plotter databases. The association of P2RY14 with immune cells and immune-related expressed genes was analyzed in the Tumor Immune Estimation Resource (TIMER) database. A retrospective analysis of the 100 patients clinical data undergoing pulmonary adenocarcinoma surgery admitted to Nanjing Chest Hospital. Immunohistochemistry (IHC) analysis was carried out to evaluate the P2RY14 expression in lung cancer tissues, and quantitative reverse transcription PCR (RT-qPCR) was used to confirm the mRNA expression of this gene in LUAD tissues. And their survival was evaluated. KM method and the log-rank test were used for univariate survival analysis, and the Cox regression method was employed for multivariate survival analysis.ResultsP2Y14 was the DEG identified by the database. P2Y14 expression was upregulated in para-cancer tissues in comparison to cancer tissues. Patients suffering from LUAD who have high P2RY14 expression had a better prognosis than those with low expression. P2RY14 expression was shown to be substantially linked with immune invasion in the TIMER database. Finally, the trial included 100 patients, of which 80 died and 20 survived with a mean overall survival (OS) of 48 months. Between the high and low expression groups of P2RY14, there were statistically significant variations in the clinical stage and differentiation degree (P<0.05). Cox regression analysis revealed that differentiation degree, smoking history, and P2RY14 expression were independent risk factors for the prognosis of LUAD patients (all P<0.05).ConclusionsP2RY14 can substantially prolong the OS of patients suffering from LUAD and can be utilized as a new LUAD predictive biomarker. P2RY14 may be related to LUAD immune invasion and have an essential role in inhibiting tumor cell immune escape within the LUAD microenvironment.
