Long non‑coding RNA AK001903 regulates tumor progression in cervical cancer

Abstract

A majority of cervical cancers are squamous cell carcinomas, arising from the squamous (flattened) epithelial cells that line the cervix. Long noncoding RNAs (lncRNAs) are a unique class of messenger RNA-like transcripts of at least 200 nucleotides in length with no significant protein-coding capacity. Aberrant lncRNA expression is emerging as a major component of the cancer transcriptome. In the present study, lncRNA microarrays were conducted to investigate the differentially expression lncRNAs in cervical cancer (CC) tissues compared with peritumoral tissues. Then, the most significantly upregulated lncRNA, which was lncRNA-AK001903 was selected to conduct further experiments. Real-time Quantitative polymerase chain reaction was conducted to investigate lncRNA-AK001903 expression in CC tissues and Hela, Siha, Ca Ski, C33a, H8 (HPV-immortalized cervical epithelial cell line) cell lines, and in situ hybridization histochemistry (ISHH) was performed to detect lncRNA-AK001903 expression level in different CC stages. The effect of lncRNA-AK001903 on cell proliferation, invasion and migration was assessed after knockdown of lncRNA-AK001903. The findings of the study confirmed that lncRNA-AK001903 was upregulated in CC cells and tissues compared with normal cell line H8 and peritumoral tissues. ISHH demonstrated that the expression level of lncRNA-AK001903 was connected with International Federation of Gynecology and Obstetrics (2018) stage of CC. Knockdown of lncRNA-AK001903 inhibited cell proliferation, invasion and migration in Ca Ski cells. In conclusion, lncRNA-AK001903 was demonstrated to be an oncogenic lncRNA that promotes tumor progression and may be an effective target for CC treatment in the near future.

Exploration of biomarkers for the diagnosis, treatment and prognosis of cervical cancer: a review

“…As miRNAs, the crucial roles of lncRNAs in cell growth, survival, cell cycle, differentiation and apoptosis have been demonstrated and their roles as molecular regulatory factors in CC may provide opportunities for early diagnosis and therapeutic targets to improve clinical outcomes [ 57 , 58 ]. lncRNA microarray analysis revealed the oncogenic lncRNA‑AK001903 which promotes tumor progression in CC [ 59 ]. Transcriptomic and lncRNA-mRNA correlation analysis showed PCBP1-AS1 as a novel prognostic biomarker for CC.…”

“…Antiproliferative activities against four human cancer cell lines (A549, HepG2, MCF-7, and SCG-7901) and two noncancerous cell lines (RAW 264.7 and human normal hepatocytes L02) (Cell Bank, Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences) were evaluated in vitro by using the CCK-8 assay according to a previously described method . Before adding the drug, the cells (3 × 10 3 cells/well) were plated into 96-well microplates and incubated with fresh culture medium for 24 h. Then, the test compounds were applied to the cells at the indicated concentrations.…”
