HOXA10 enhances cell proliferation and suppresses apoptosis in esophageal cancer via activating p38/ERK signaling pathway

EIF4A3 induced circGRIK2 promotes the malignancy of glioma by regulating the miR-1303/HOXA10 axis

In recent years, the role of circular RNAs (circRNAs) in glioma has become increasingly important. However, there are still many newly discovered circRNAs with unknown functions that require further study. In this study, circRNA sequencing, qPCR, MTS, EdU, Transwell, and other assays were conducted to detect the expression and malignant effects of a novel circRNA molecule, circGRIK2, in glioma. qPCR, western blotting, RIP, and luciferase reporter gene experiments were used to investigate the downstream molecular mechanisms of circGRIK2. Our study found that circGRIK2 was highly expressed in glioma and promoted glioma cell viability, proliferation, invasion, and migration. Mechanistically, circGRIK2 acted as a competitive sponge for miR-1303, upregulating the expression of HOXA10 to exert its oncogenic effects. Additionally, the RNA-binding protein EIF4A3 could bind to and stabilize circGRIK2, leading to its high expression in glioblastoma. The discovery of circGRIK2 in this study not only contributes to a better understanding of the biological mechanisms of circGRIK2 in glioma but also provides a new target for molecular targeted therapy.

HOXA10 DNA Methylation Level in the Endometrium Women with Endometriosis: A Systematic Review

Endometriosis is an inflammatory chronic systemic disease resulting in pelvic pain and infertility. However, despite a high prevalence of endometriosis, disease identification is still insufficient, and a high percentage of misdiagnosing was observed. Hence, a comprehensive study needs to be done to improve our understanding of the pathogenesis of endometriosis. Aberrant hypermethylation of HOXA10 has been reported to play a role in endometriosis. Thus, a comprehensive literature search was conducted to identify the DNA methylation level of HOXA10 among endometriosis patients across populations. The literature search was done using PubMed, Scopus, EBSCOhost, and Science Direct applying (HOXA10 OR "homeobox A10" OR "HOXA-10" OR HOX1) AND ("DNA methylation" OR methylation) AND (endometriosis OR endometrioma) as keywords. From 491 retrieved studies, five original articles investigating the DNA methylation level of HOXA10 from endometrium tissues among endometriosis women were included. All five included studies were classified as high-quality studies. High HOXA10 DNA methylation level was observed in the endometrium tissue of women with endometriosis in all the included studies. The secretory phase was identified as the best sampling time for HOXA10 DNA methylation study in endometriosis, and the most studied DNA methylation site is the promoter region of the HOXA10. However, more studies are needed to expose the HOXA10 mechanism in the pathogenesis of endometriosis.
