High expression of <i>HOXA4</i> in patients with glioma indicates unfavorable clinical outcomes
<p><i>HOXA4</i> is a novel oncogene that has been observed in many kinds of tumors, but its role during glioma carcinogenesis and its clinical significance in diagnosing and prognosis human glioma remains unknown. In the present study, the Chinese Glioma Atlas (CGGA)-RNA sequencing database, CGGA microarray, and The Cancer Genome Atlas (TCGA)-RNA seq data from 1674 glioma patients were obtained from online databases and analyzed using quantitative reverse transcription-polymerase chain reaction (RT-qPCR) to detect changes in the expression level of <i>HOXA4</i> and characterize the relationship between <i>HOXA4</i> and the clinical characteristics and prognosis of patients with glioma. Gene set enrichment analysis (GSEA) was used to reveal how <i>HOXA4</i> regulates tumor-related pathways. <i>HOXA4</i> mRNA levels in glioma tissue were higher than those in adjacent brain tissue. <i>HOXA4</i> expression was also closely related to the clinical and molecular characteristics of gliomas, such as tumor grade and isocitrate dehydrogenase (IDH) mutation. Functional enrichment analysis revealed that <i>HOXA4</i> could regulate cancer-related signal pathways, such as Cell cycle, Cell adhesion molecules cams, and JAK/STAT signaling pathway. Results of <i>in vitro</i> experiments confirmed that knockdown of HOXA4 blocks the cell cycle pathway and inhibits the proliferation, invasion and chemotherapy resistance in gliomas. We concluded that <i>HOXA4</i> was an independent risk factor for glioma and may have clinical diagnostic potential. Meanwhile, our findings revealed that <i>HOXA4</i> could be used as a biomarker for glioma diagnosis and treatment.</p>
