Tissue specimen:

NSCLC tissue; normal lung tissues; tumor tissues

Cell lines:

HCC827; A549; BEAS-2B

In vivo animal model:

cell line-derived xenograft

circRNA-disease information
Expression pattern:
UP
Associated gene: KLF8, Ago2
Associated microRNA: miR-1253
Biological function: Promotes NSCLC cell proliferation and glycolysis and inhibits apoptosis; promotes tumor formation in vivo.
Molecular mechanism: Acts as a miR-1253 sponge to upregulate KLF8 (ceRNA mechanism), thereby promoting malignant phenotypes and glycolysis.
Biological pathway or process:

proliferation (promotes); apoptosis (inhibits); glycolysis (promotes); ceRNA regulation (promotes)

Detected method:
Q
Validation methods:

RT-qPCR; divergent primers PCR; RNase R Treatment; Actinomycin D / DRB Stability Assay; Luciferase Reporter Assay; RIP (RNA Immunoprecipitation); Transfection; Colony Formation Assay; EdU Staining; Annexin V/PI Flow Cytometry; Western Blot; IHC (Immunohistochemistry); In Vivo Animal Model

Clinical significance:

CircSEC24A expression was significantly associated with distant metastasis, T stage, and TNM stages of NSCLC patients.

Description:

CircSEC24A is up-regulated in NSCLC tissues and cell lines and functions as an oncogenic circRNA. It sponges miR-1253 to de-repress KLF8, thereby promoting proliferation and glycolysis while inhibiting apoptosis, and its knockdown suppresses xenograft tumor growth.

Confidence score:

0.7975

Other information
Title:

CircSEC24A induces KLF8 expression to promote the malignant progression of non-small cell lung cancer by regulating miR-1253.
