Electroacupuncture improves TBI dysfunction by targeting HDAC overexpression and BDNF-associated Akt/GSK-3β signaling.

ABSTRACT:

Background

Acupuncture or electroacupuncture (EA) appears to be a potential treatment in acute clinical traumatic brain injury (TBI); however, it remains uncertain whether acupuncture affects post-TBI histone deacetylase (HDAC) expression or impacts other biochemical/neurobiological events.

Materials and methods

We used behavioral testing, Western blot, and immunohistochemistry analysis to evaluate the cellular and molecular effects of EA at LI4 and LI11 in both weight drop-impact acceleration (WD)- and controlled cortical impact (CCI)-induced TBI models.

Results

Both WD- and CCI-induced TBI caused behavioral dysfunction, increased cortical levels of HDAC1 and HDAC3 isoforms, activated microglia and astrocytes, and decreased cortical levels of BDNF as well as its downstream mediators phosphorylated-Akt and phosphorylated-GSK-3β. Application of EA reversed motor, sensorimotor, and learning/memory deficits. EA also restored overexpression of HDAC1 and HDAC3, and recovered downregulation of BDNF-associated signaling in the cortex of TBI mice.

Conclusion

The results strongly suggest that acupuncture has multiple benefits against TBI-associated adverse behavioral and biochemical effects and that the underlying mechanisms are likely mediated by targeting HDAC overexpression and aberrant BDNF-associated Akt/GSK-3 signaling.

Project description:RationaleEndothelial progenitor cells (EPCs) respond to stromal cell-derived factor 1 (SDF-1) through chemokine receptors CXCR7 and CXCR4. Whether SDF-1 receptors involves in diabetes mellitus-induced EPCs dysfunction remains unknown.ObjectiveTo determine the role of SDF-1 receptors in diabetic EPCs dysfunction.Methods and resultsCXCR7 expression, but not CXCR4 was reduced in EPCs from db/db mice, which coincided with impaired tube formation. Knockdown of CXCR7 impaired tube formation of EPCs from normal mice, whereas upregulation of CXCR7 rescued angiogenic function of EPCs from db/db mice. In normal EPCs treated with oxidized low-density lipoprotein or high glucose also reduced CXCR7 expression, impaired tube formation, and increased oxidative stress and apoptosis. The damaging effects of oxidized low-density lipoprotein or high glucose were markedly reduced by SDF-1 pretreatment in EPCs transduced with CXCR7 lentivirus but not in EPCs transduced with control lentivirus. Most importantly, EPCs transduced with CXCR7 lentivirus were superior to EPCs transduced with control lentivirus for therapy of ischemic limbs in db/db mice. Mechanistic studies demonstrated that oxidized low-density lipoprotein or high glucose inhibited protein kinase B and glycogen synthase kinase-3β phosphorylation, nuclear export of Fyn and nuclear localization of nuclear factor (erythroid-derived 2)-like 2 (Nrf2), blunting Nrf2 downstream target genes heme oxygenase-1, NAD(P)H dehydrogenase (quinone 1) and catalase, and inducing an increase in EPC oxidative stress. This destructive cascade was blocked by SDF-1 treatment in EPCs transduced with CXCR7 lentivirus. Furthermore, inhibition of phosphatidylinositol 3-kinase/protein kinase B prevented SDF-1/CXCR7-mediated Nrf2 activation and blocked angiogenic repair. Moreover, Nrf2 knockdown almost completely abolished the protective effects of SDF-1/CXCR7 on EPC function in vitro and in vivo.ConclusionsElevated expression of CXCR7 enhances EPC resistance to diabetes mellitus-induced oxidative damage and improves therapeutic efficacy of EPCs in treating diabetic limb ischemia. The benefits of CXCR7 are mediated predominantly by a protein kinase B/glycogen synthase kinase-3β/Fyn pathway via increased activity of Nrf2.

Project description:BackgroundAbnormal expression of Fanconi anaemia complementation group I (FANCI) has been implicated in carcinogenesis. However, the precise role of FANCI in the development of hepatocellular carcinoma (HCC) remains unclear.Materials & methodsWe conducted a comprehensive bioinformatics analysis of FANCI's role based on HCC patient sequencing data in the TCGA and GEO databases. Then, we performed qPCR, Western blotting (WB), and immunohistochemistry (IHC) assays. SiRNA-mediated knockdown of FANCI was conducted, followed by CCK-8, EdU staining, and colony formation experiments to evaluate the impact of FANCI knockdown on HCC cell behaviour. Flow cytometry was employed to explore alterations in the cell cycle after FANCI knockdown in HCC cell lines. Furthermore, RNA sequencing was performed to investigate potential mechanisms following FANCI knockdown, and WB analysis was used to validate the corresponding pathway.ResultsOur bioinformatics analysis revealed elevated expression of FANCI in HCC, which was subsequently validated through qPCR, WB, and IHC assays. High expression of FANCI was significantly associated with a poor prognosis in HCC patients. Univariate and multivariate Cox regression analyses identified FANCI as an independent prognostic risk factor for HCC patients. Additionally, the coexpressed genes of FANCI were found to be associated with multiple cancer pathways. Knockdown of FANCI expression significantly inhibited HCC cell proliferation and colony formation by inducing cell cycle arrest. Further WB analysis revealed that FANCI knockdown suppressed the expression of Cyclin D1 and p-AKT while increasing the expression of GSK-3β in HCC cells. However, no significant differences were observed in the expression levels of AKT and PI3K.ConclusionOverall, our research provides substantial proof of FANCI's crucial function as an oncogene in HCC. It could serve as a potential prognostic marker, therapeutic target, and tumorigenic factor in HCC.
