The F3′5′H gene family plays an important role in regulating anthocyanin biosynthesis,abiotic stress,and hormone signaling.In this study,14 F3′5′H genes were identified from the blueberry genome.The chromosomal distribution,physicochemical properties,F3′5′H domain,conserved motifs,cis-acting elements,and intron/exon compositions were analyzed.The functional prediction analysis of these VcF3′5′Hs indicated that their biological functions included light response and other secondary metabolites.The results of qRT-PCR showed that VcF3′5′Hs(especially VcF3′5′H4)were highly expressed at the ripening stage.Subcellular localization revealed that VcF3′5′H4 may be located in the endoplasmic reticulum.Co-expression analysis showed that the VcF3′5′H gene family was related to anthocyanin.This research provides an overview of the blueberry F3′5′H family and helps verify the role of these genes in regulating anthocyanin biosynthesis. 展开更多

Objective To analyze the differential gene expression profile of serum exosomes in patients with acute cerebral infarction(ACI)and clarify the changes in gene expression related to cerebral infarction injury and the potential serum markers.Methods Four patients with ACI and five healthy people were enrolled in the PhaseⅠstudy.After serum isolation from peripheral blood,exosomes were extracted with exosomes kits,highthroughput detection of m RNA was performed with gene chips,and differentially expressed m RNAs were screened.Gene Ontology(GO)functional analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis were performed simultaneously.Furthermore,real-time polymerase chain reaction(q RT-PCR)was used to verify the expression levels of the screened differential m RNAs in the serum exosomes collected in PhaseⅡfrom 32 patients each in the ACI case and normal control groups.Results In the PhaseⅠstudy,there were 248 differentially expressed m RNAs(fold change≥2.0,P<0.05)among five patients in the normal control group and four patients in the case group,of which the expression of 242 was upregulated and that of six was downregulated.The results of GO functional enrichment analysis mainly included behavior regulation,cell connection,and antioxidant activity.The results of KEGG pathway enrichment analysis mainly included ribosomes,proteasomes,oxytocin signaling pathways,and oxidative phosphorylation.After researching and screening based on relevant literature,it was found that among the genes with significant differential expression,H3 F3 B m RNA may be associated with and might play an important role in ACI.The q RT-PCR method was used to detect the H3 F3 B mRNA expression in serum exosomes of 32 patients each in the normal control and case groups in PhaseⅡ;the expression was significantly higher in serum exosomes of the case group than in those of the normal control group(P<0.001).H3 F3 B mRNA expression in serum exosomes of the case group positively correlated with age,the National Institutes of Health Stroke Scale(NIHSS)score,and the maximum infarct size(P<0.05).Conclusion ACI can lead to changes in the serum exosomes mRNA expression profile,which may be closely related to the occurrence,development,and prognosis of this condition.These findings will provide direction for research on the molecular mechanism,diagnostic markers,and therapeutic targets of ACI. 展开更多
