Objective:
The screening and monitoring of lung adenocarcinoma (LUAD) is critical for its therapeutic efficiency. This study explored a novel biomarker of LUAD from the GSE146689 dataset and evaluated its function aiming to provide a potential therapeutic target for LUAD.
Methods:
There were 126 LUAD patients, 75 benign lung disease patients, and 57 healthy individuals enrolled in this study. circ_0001681 levels were evaluated by PCR, and its significance in the diagnosis and prognosis of LUAD was assessed by ROC and Cox regression analysis. The effect of circ_0001681 on LUAD cells was investigated by CCK8 and transwell assays.
Results:
Reduced circ_0001681 was observed in LUAD patients relative to benign lung disease patients and healthy individuals, which could discriminate LUAD patients. circ_0001681 downregulation was closely associated with the severity and malignancy of LUAD patients, and it also indicated the adverse prognosis of LUAD. In mechanism, circ_0001681 could negatively regulate miR-567, which was found to mediate the inhibitory effect of circ_0001681 on LUAD cell proliferation and motility.
Conclusion:
Decreased circ_0001681 in LUAD served as a biomarker in tumor occurrence and development, which can be included in the formulation and adjustment of LUAD therapeutic strategy.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
