KLF3 Transcription Activates WNT1 and Promotes the Growth and Metastasis of Gastric Cancer via Activation of the WNT/β-Catenin Signaling Pathway.

The transcription factor Krüppel-like factor (KLF) 3 is one of the members of the KLF family, which plays an important role in tumor progression. Nevertheless, the role of KLF3 in the growth and metastasis of gastric cancer (GC) still needs to be elucidated. Bioinformatics analysis showed that KLF3 was overexpressed in patients with GC, and the high expression of KLF3 was correlated with poor survival.

lncRNA PCAT19 negatively regulates p53 in non-small cell lung cancer.

The present study aimed to investigate the influence of long non-coding (lnc)RNA prostate cancer associated transcript (PCAT)19 on the progression of non-small cell lung cancer (NSCLC). It was determined that PCAT19 expression was upregulated in NSCLC tissues and also predicted poor patient survival rate. Additionally, p53 expression was downregulated in NSCLC specimens, which was negatively correlated with PCAT19 expression.

Overexpression of circ-0067934 is associated with increased cellular proliferation and the prognosis of non-small cell lung cancer.

Previous studies have suggested that circular RNAs (circRNAs) serve crucial functions in various human diseases, including cancer. The results of the present study demonstrated that the expression levels of circ-0067934 were significantly increased in non-small cell lung cancer (NSCLC) tissues and NSCLC cells compared with that in adjacent normal tissues and a normal human bronchial epithelium cell line, as assessed using reverse transcription-quantitative polymerase chain reaction. Increased expression levels of circ-0067934 were associated with lymph node metastasis and advanced tumor stage in patients with NSCLC.

MiR-338 suppresses cell proliferation and invasion by targeting CTBP2 in glioma.

Background: Previous studies indicated that microRNA-338-5p (miR-338-5p) functions as tumor suppressor in some cancer types including glioma. However, the clinical significance and biological function of miR-338-5p in glioma still need to be explored.

Methods: We used quantitative real time PCR (qRT-PCR) to detect the miR-338-5p expression in the 44 cases of glioma tissues and adjacent normal tissues.
