In summary, our results suggest that miR-21, miR-205, miR-30d, and miR-24 may serve as potential novel non-invasive biomarkers for diagnosis of lung cancer.
Taken together our findings imply that the miRNAs miR-205 and miR-218 play a key role in the development of lung cancer acquired chemoresistance and the tumor suppressor role of miR-218 in inhibiting lung cancer cell tumorigenesis and overcoming platinum chemoresistance is significant for future cancer therapeutic approaches.
RESULTS These results indicate that the functional association of rs3842530 in miR-205HG and lung cancer might provide a possible explanation for the tissue-dependent function of miR-205 in different tumors.
The present results suggested that the increased miR‑205‑5p expression observed in non‑small cell lung cancer tissues may contribute to increased proliferation and invasion of lung cancer cells and thus to cancer progression.
In addition, upregulation of miR-205-5p, miR-3917 and downregulation of miR-30a-3p, miR-30a-5p, miR-30c-2-3p, miR-30d-5p, miR-27a-5p increased the risk of lung cancer by conditional logistic regression analysis.
MicroRNA205 (miR-205), as a significant tumor biomarker, is of vital importance for diagnosis of lung cancer and its overexpression patterns have been extensively studied.
MicroRNA‑205 (miR‑205) has been reported to be downregulated, and serves critical roles in the pathogenesis and progression of several types of cancer, including breast, prostate and lung cancer.
Trace levels of microRNA-205, known as a biomarker of lung cancer, in human serum was quantified for the first-time using G-quadruplex DNAzyme linked to detection complementary probe and 1,1'-oxalyldiimidazole chemiluminescence (ODI-CL).
