Research progress on relationship between N6-adenylate methylation modification and cell transformation and associated mechanism / 环境与职业医学

As a reversible and dynamic epigenetic marker, N6-adenylate methylation (m6A) modification is the most common mRNA modification in eukaryotes. This paper briefly described how m6A can influence RNA splicing, stability, and translation after transcription, and then participate in a variety of signaling pathways and biological and pathological processes, regulating cell proliferation, apoptosis, epithelial mesenchymal transformation (EMT) processes, and tumor invasion and metastasis. In addition, according to current studies, m6A methyltransferases (writers) are believed to promote EMT and tumor development, and readers and erasers both promote and inhibit EMT in different research objects. In this review, we summarized the mechanism of m6A modification and its role in cell transformation, and pointed out the direction of disease treatment.

Modification of m6 A in human embryonic lung fibroblasts induced by neodymium oxide exposure and its mechanism / 环境与职业医学

Background Occupational and environmental particulate matter may cause fibrosis, accompanied by RNA m6A modification changes. Neodymium oxide (Nd2O3) can cause mouse lung fibrosis, which contains a large number of fibroblasts. Objective To investigate m6A modification of tumor necrosis factor receptor-associated protein 6/nuclear factor-κB (TRAF6/NF-κB) signaling pathway in fibrosis of human embryonic lung fibroblasts induced by Nd2O3, and identify the key m6A modification sites of TRAF6. Methods Designed concentrations of Nd2O3 (0, 1.563, 3.125, 6.25, 12.5, 25, 50, 100, and 200 mg∙L−1) were infected with HELF cells for 24 and 48 h, and cell viability was detected to determine exposure time and dose. Measurements included indicators of fibrosis [hydroxyproline (HYP) and transforming growth factor-β1 (TGF-β1)], m6A methylation level, methyltransferases (METTL3 and METTL14), demethylases (FTO and ALKBH5), reading proteins (YTHDC2 and YTHDF2), fibrosis-associated genes (collagen-І, vimentin, and α-SMA), and proteins related to signaling pathway (TRAF6, NFKB1, P65, and P-P65). The enrichment of m6A in TRAF6 mRNA was measured by methylated RNA immunoprecipitation-quantitative real-time PCR (MeRIP-qPCR). Results The results of cell viability indicated that 6.25, 12.5, 25 mg∙L−1 Nd2O3 and 48 h exposure time were used for subsequent experiments. After 48 h exposure, compared with the control group, the HYP level in the 25 mg∙L−1 Nd2O3 group was increased, and the levels of TGF-β1 in the 6.25, 12.5, and 25 mg∙L−1 Nd2O3 groups were increased (P<0.05); the overall m6A methylation levels of HELF cells in the 12.5 and 25 mg∙L−1 Nd2O3 groups were increased (P<0.05). At mRNA level, compared with the control group, the mRNA expression levels of methyltransferases METTL3 and METTL14 (6.25, 12.5, and 25 mg∙L−1 Nd2O3) were increased (P<0.05); the mRNA expression level of reading protein YTHDF2 (6.25, 12.5, and 25 mg∙L−1 Nd2O3) was increased (P<0.05), while the mRNA expression level of YTHDC2 (25 mg∙L−1 Nd2O3) was decreased (P<0.05); the mRNA expression levels of demethylases FTO (12.5 and 25 mg∙L−1 Nd2O3) and ALKBH5 (25 mg∙L−1 Nd2O3) were decreased (P<0.05); the mRNA expression levels of fibrosis-related genes vimentin, α-SMA, and collagen-Ⅰ (6.25, 12.5, and 25 mg∙L−1 Nd2O3) were increased (P<0.05); the mRNA expression levels of pathway-related genes TRAF6 (25 mg∙L−1 Nd2O3) and NFKB1 (12.5 and 25 mg∙L−1 Nd2O3) were increased (P<0.05). At protein level, compared with the control group, the expression levels of methyltransferases METTL3 (25 mg∙L−1 Nd2O3) and METTL14 (12.5 and 25 mg∙L−1 Nd2O3) were increased (P<0.05); the expression level of reading protein YTHDF2 (12.5 and 25 mg∙L−1 Nd2O3) was increased, while the expression level of YTHDC2 (25 mg∙L−1 Nd2O3) was decreased (P<0.05); the expression level of demethylase FTO (25 mg∙L−1 Nd2O3) was decreased (P<0.05); the expression level of fibrosis-associated protein vimentin was increased at 25 mg∙L−1 Nd2O3, and the expression levels of α-SMA and collagen-Ⅰ were increased at 12.5 and 25 mg∙L−1 Nd2O3 (P<0.05); the expression levels of TRAF6 and P-P65 were increased at 25 mg∙L−1 Nd2O3 (P<0.05). The MeRIP-qPCR results showed that compared with the control group, the concentrations of m6A in all Nd2O3 groups were significantly increased (P<0.05). Conclusions Upon exposure of HELF cells to Nd2O3, the alterations in fibrosis-related indexes increase the expression of some m6A methylases and decrease the expression of demethylases, thereby increasing the m6A methylase level, and may promote the progression of fibrosis by activating the TRAF6/NF-κB signaling pathway.

The intervention effect of traditional Chinese medicine on meningeal nuclear factor expression of rats suffering from migraine / 生物医学工程学杂志

This animal experiment was made to probe into the mechanism by which traditional Chinese medicine interferes with the meningeal nuclear factor of rats suffering from migraine. The adult SD rats were selected, and the Cristina Tassorelli method was adopted for the preparation of the migraine models, which were classified into the normal group, model group and traditional Chinese medicine group respectively, and the latter two groups were further divided, in terms of intervals, into 0.5 h, 1.5 h, 2.5 h and 4 h groups, with the model group as control. Real-time quantitative RT-PCR technology was employed to test and measure the gene expression of meningeal nuclear factor of rats. The results showed that when the level of NF-kappaB mRNA expression in the model group was compared with that in 0.5 h group, 1.5 h group and 2.5 h group, there was no significant difference (P > 0.05), but when compared with that in the 4h group, there was significant difference (P < 0.05). Intervention by traditional Chinese medicine in the gene expression of meningeal nuclear factor of model rats suffering from migraine can restrain at different degree the expression of abnormally increasing miningeal nuclear factor NF-kappaB mRNA, which suggests that the intervention by traditional Chinese medicine may enable improvement and treatment of the obstacle of the constriction and dilation system of cerebral blood vessels through restraining excessive expression of meningeal NF-kappaB genes. This conclusion could serve as a theoretical basis for developing traditional Chinese medicine, which takes the NF-kappaB as the target point and the treatment time window, and have underpins an objective approach to the clinical treatment of migraine.
