Polo like kinase 1 expression in cervical cancer tissues generated from multiple detection methods.

Background: Existing studies of PLK1 in cervical cancer had several flaws. The methods adopted by those studies of detecting PLK1 expression in cervical cancer were single and there lacks comprehensive evaluation of the clinico-pathological significance of PLK1 in cervical cancer.

Methods: A total of 303 cervical tissue samples were collected for in-house tissue microarrays.

Clinical value of microRNA-198-5p downregulation in lung adenocarcinoma and its potential pathways.

Lung adenocarcinoma (LUAD), the main subtype of non-small cell lung cancer, is known to be regulated by various microRNAs (miRs/miRNAs); however, the role of miR-198-5p in LUAD has not been clarified. In the present study, the clinical value of miR-198-5p in LUAD and its potential molecular mechanism was evaluated. miR-198-5p expression was examined by reverse transcription-quantitative PCR (RT-qPCR) in 101 paired LUAD and adjacent normal lung tissues.

Expression levels and co‑targets of miRNA‑126‑3p and miRNA‑126‑5p in lung adenocarcinoma tissues: Αn exploration with RT‑qPCR, microarray and bioinformatic analyses.

Lung adenocarcinoma (LUAD) is the most common histological subtype of lung cancer. Previous studies have found that many microRNAs (miRNAs), including miRNA‑126‑3p, may play a critical role in the development of LUAD. However, no study of LUAD has researched the synergistic effects and co‑targets of both miRNA‑126‑3p and miRNA‑126‑5p.

Clinical Value and Prospective Pathway Signaling of MicroRNA-375 in Lung Adenocarcinoma: A Study Based on the Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO) and Bioinformatics Analysis.

BACKGROUND Lung adenocarcinoma (LUAD) is the most frequent lung cancer. MicroRNAs (miRNAs) are believed to have fundamental roles in tumorigenesis of LUAD. Although miRNAs are broadly recognized in LUAD, the role of microRNA-375 in LUAD is still not fully elucidated.

Implication of downregulation and prospective pathway signaling of microRNA-375 in lung squamous cell carcinoma.

Background: Lung cancer is one of the most typical cancers in the world. Altered expression profiles of microRNA-375(miR-375) are linked to many diseases including lung cancer. However, the relationship between miR-375 and lung squamous cell carcinoma (LUSC) is controversial.

Upregulation and clinicopathological significance of long non-coding NEAT1 RNA in NSCLC tissues.

Background: Recent reports have shown that nuclear enriched abundant transcript 1 (NEAT1), a long non- coding RNA (lncRNA), contributes to the precise control of gene expression and is related to several human malignancies. However, limited data are available on the expression and function of NEAT1 in lung cancer. The major objective of the current study was to profile the expression and clinicopathological significance of NEAT1 in non-small cell lung cancers (NSCLCs).
