Abstract
Glioma is considered to be the most common brain malignancy in the central nervous system. At present, the aetiology of glioma is not clear. Due to its rapidly growth and easily recurrence, the prognosis of patients with glioma is very poor. N6-methyladenosine (m6A) methylation is an internal reversible modification in most RNAs, including messenger RNAs (mRNAs) and noncoding RNAs (ncRNAs). Recent studies have shown that the m6A regulators are abnormal expressed, and are extensively involved in the progression of glioma by targeting ncRNAs. Moreover, as the most important epigenetic regulators, ncRNAs can also affect the function of m6A regulators in glioma. This review summarized the expression and function of certain common m6A regulators in glioma. Also, the current review sum up the mutual interactions between m6A regulators and ncRNAs in glioma.

Abstract
Glioblastoma is one of the most dangerous tumors for patients in clinical practice at present, and since glioblastoma originates from the brain, it will have a serious impact on patients. Therefore, more effective clinical therapeutic targets are still needed at this stage. Kinesin family member 15 (KIF15) promotes proliferation in several cancers, but its effect on glioblastoma is unclear. In this study, differentially expressed gene analysis and network analysis were performed to identify critical genes affecting glioma progression. The samples were divided into a KIF15 high-expression group and KIF15 low-expression group, and the association between FIK15 expression level and clinical characteristics was summarized and analyzed by performing medical data analysis; the effect of KIF15 on glioblastoma cell proliferation was detected by employing colony formation and MTT assays. The effect of KIF15 on tumor growth in mice was determined. It was found that KIF15 was a potential gene affecting the progression of glioblastoma. In addition, KIF15 was highly expressed in glioblastoma tumor tissues, and KIF15 was correlated with tumor size, clinical stage and other clinical characteristics. After the KIF15 gene was knocked out, the proliferation ability of glioblastoma was significantly inhibited. KIF15 also contributed to the growth of glioblastoma tumors in mice. Therefore, we found KIF15 to be a promising clinical therapeutic target.

Front Mol Neurosci 2022; 15:844568.

Abstract
Kif15, a kinesin family member, is powerful in the formation of bipolar spindles. There is emerging evidence indicating that Kif15 plays vital roles in influencing the growth of axons and interference with the progression of the tumor. However, the function of Kif15 in the auditory organs remains unknown. The Western blotting test was used to examine the effect of Kif15 downregulation by specific morpholino targeting Kif15 (Kif15-MO). The development of the inner ear and posterior lateral line (PLL) system in zebrafish was under continuous observation from spawns to 96 h postfertilization (hpf) to investigate the potential role of Kif15 in the auditory and vestibular system. We uncovered that Kif15 inhibition induced otic organ deformities in zebrafish, including malformed semicircular canals, abnormal number and location of otoliths, and reduced number of hair cells (HCs) both in utricle and saccule. Furthermore, a remarkable reduction in the number of PLL neuromasts was also explored in Kif15-MO morphants compared to the normal larvae. We also detected notably reduced activity in locomotion after Kif15 was knocked down. Additionally, we performed rescue experiments with co-injection of Kif15 mRNA and found that the Kif15 splicing MO-induced deformities in otic vesicle and PLL of zebrafish were successfully rescued, and the severely reduced locomotor activity caused by Kif15-MO was partially rescued compared to the control-MO (Con-MO) embryos. Our findings uncover that Kif15 is essential in the early development of auditory and vestibular organs using zebrafish as models.
