Approximately 70% epilepsy may be associated with genetic etiology. To date, more than 2 900 genes related to epilepsy have been reported, and genotype-phenotype association in epilepsy has received increasing attention. Explaining how mutations in the same gene can lead to different diseases or phenotypes remains challenging. Sub-molecular mechanisms, including functional structural domains, amino acid substitutions, isoforms, and monoallelic/biallelic mutations, provide new perspectives for deciphering genotype-phenotype association in epilepsy. This review summarizes the role of sub-molecular mechanisms in genotype-phenotype association in epilepsy, to provide new strategies for clinical diagnosis and precise treatment of epilepsy.

AIM:This study aims to investigate the role of dynamin-related protein 1(Drp1)in the A1 type activation of astrocytes and elucidate the underlying mechanism of abnormal astrocyte activation.METHODS:Rat astro-cyte line CTX-TNA2 was divided into control group,astrocyte-conditioned medium(ACM)group,and 5,10 and 25 μmol/L mitochondrial division inhibitor-1(Mdivi-1;a selective inhibitor of Drp1)+ACM group.The cells in ACM group were exposed to ACM containing interleukin-1α(IL-1α),tumor necrosis factor-α(TNF-α)and complement 1q(C1q)for 24 h to induce type A1 activation,while those in Mdivi-1+ACM group were pre-treated with various concentrations of Mdi-vi-1 for 2 h before stimulation with ACM for 24 h.RT-qPCR was used to detect the expression levels of A1 type activation-related indicators IL-1β,TNF-α and IL-10 mRNA in each group.Immunofluorescence was utilized to assess the expres-sion levels of A1 type activation marker molecules C3,inducible nitric oxide synthase(iNOS)and S100 calcium binding protein A10(S100A10).The level of mitochondrial reactive oxygen species(ROS)was measured using MitoSOX Red staining and flow cytometry analysis.The mitochondrial morphology was observed using the MICA full-field imaging analy-sis platform.Lastly,the expression level of mitochondrial fission protein 1(FIS1)and the activation level of Drp1 in each group were evaluated through immunoblotting analysis.RESULTS:The RT-qPCR and immunofluorescence results indi-cated that the ACM group exhibited significantly elevated levels of IL-1β and TNF-α mRNA,and C3 protein expression compared with control group,along with increased iNOS protein expression and reduced IL-10 mRNA and S100A10 pro-tein expression(P<0.05).Interventions with 10 and 25 μmol/L Mdivi-1 effectively inhibited the rise in IL-1β and TNF-α mRNA,and C3 and iNOS protein expression induced by ACM,while promoting S100A10 expression.MitoSOX Red staining revealed a significant increase in mitochondrial ROS levels in astrocytes stimulated by ACM,which was effectively re-versed by Mdivi-1 intervention.The MICA full-field imaging analysis platform demonstrated that ACM induced the forma-tion of round-shaped mitochondria in astrocytes,while 10 and 25 μmol/L Mdivi-1 interventions facilitated the restoration of their tubular shape.Additionally,Western blot results confirmed that Mdivi-1 intervention effectively reversed the acti-vation of Drp1 and FIS1.CONCLUSION:The Drp1-mediated mitochondrial fission represents one of the intrinsic molecu-lar mechanisms underlying A1 type activation of astrocytes,and Mdivi-1,as a selective inhibitor of Drp1,can effectively inhibit abnormal astrocyte activation.

Circular RNAs (circRNAs) are endogenous non-coding RNAs with covalently closed structures, which have important functions in plants. However, their biogenesis, degradation, and function upon treatment with gibberellins (GAs) and auxins (1-naphthaleneacetic acid, NAA) remain unknown. Here, we systematically identified and characterized the expression patterns, evolutionary conservation, genomic features, and internal structures of circRNAs using RNase R-treated libraries from moso bamboo (Phyllostachys edulis) seedlings. Moreover, we investigated the biogenesis of circRNAs dependent on both cis- and trans-regulation. We explored the function of circRNAs, including their roles in regulating microRNA (miRNA)-related genes and modulating the alternative splicing of their linear counterparts. Importantly, we developed a customized degradome sequencing approach to detect miRNA-mediated cleavage of circRNAs. Finally, we presented a comprehensive view of the participation of circRNAs in the regulation of hormone metabolism upon treatment of bamboo seedlings with GA and NAA. Collectively, our study provides insights into the biogenesis, function, and miRNA-mediated degradation of circRNAs in moso bamboo.

sis and its possible mechanism.
:

Results :
Compared with sham group , the expression of Bax , cleaved Caspase3 protein increased and the expression of Bcl⁃2 protein decreased in LPS group. Compared with LPS group , the injury in APN + LPS group was significantly alleviated , showing that the expression of Bax , cleaved caspase3 protein decreased and the expression of Bcl⁃2 protein increased. Meanwhile , compared with sham group , the expression of Cx43 increased in LPS group and decreased in APN + LPS group.
Conclusion
Adiponectin can attenuate LPS⁃induced cardiac injury in septic mice. The mechanism may be through the inhibition of apoptotic signal pathway and the expression of Cx43.

OBJECTIVE:To preliminarily s tudy the potential mechanism of astragaloside Ⅳ on allergic rhinitis (AR)model mice. METHODS :C57/BL6 mice were randomly divided into blank group ,model group and astragaloside Ⅳ group,with 10 mice in each group. Except for blank group ,AR model was prepared by sensitization and challenge with ovalbumin on day 0,7,14 and 21-27. Astragaloside Ⅳ group was given astragaloside Ⅳ 40 mg/kg intraperitoneally at the dose of 0.02 mL/g on the 15th to 27th day of modeling (given the drug 1 h before challenge sensitization on the 21st to 27th day ). Blank group and model group were given constant volume of normal saline intraperitoneally ,once a day. Twenty-four hours after sensitization from the last challenge , the infiltration of inflammatory cells in the nasal mucosa of each group was observed ,and the contents of interleukin 4(IL-4), IL-5 and interferon gamma (IFN-γ)in the nasal lavage fluid were measured. The levels of reactive oxygen species (ROS),and the count of phosphorylated Janus kinase 2(p-JAK2)and phosphorylation signal transduction and activation of transcription protein 6 (p-STAT6)positive cells in the nasal mucosa and spleen as well as the phosphorylation levels of JAK 2 and STAT 6 proteins in spleen tissue (i.e. p-JAK 2/JAK2 ratio,p-STAT6/STAT6 ratio)were also determined. RESULTS :Compared with blank group ,the number of inflammatory cells in the nasal mucosa (eosinophils and mast cells )in the model group ,the contents of IL- 4 and IL- 5 in the nasal lavage fluid ,and the levels of ROS in the nasal mucosa and spleen tissues in the model group ,the count of p-JAK 2 and p-STAT 6 positive cells increased significantly ,the p-JAK2/JAK2 ratio,p-STAT6/STAT6 ratio in the spleen tissue were significantly increased (P<0.05),and the content of INF-γ in the nasal lavage fluid was significantly decreased(P<0.05). Compared with model group ,the count of inflammatory cells infiltrated in the nasal mucosa ,the contents of IL- 4 and IL- 5 in the nasal cavity lavage fluid ,the level of ROS and the number of p-JAK 2 and p-STAT 6 positive cellsin the nasal mucosa and spleen tissue as well as the p-JAK2/JAK2 ratio and p-STAT 6/STAT6 ratio in spleen tissue were decreased significantly (P<0.05),and the content of INF-γ in nasal lavage fluid was significantly increased(P<0.05). CO NCLUSIONS:Astragaloside Ⅳ can effectively improve the inflammatory response in AR model mice ,the mechanism of which may be related to down-regulation of JAK2/STAT6 signaling pathway and ROS level.
