文摘The persistence of covalently closed circular DNA(cccDNA)in hepatitis B virus(HBV)-infected hepatocytes remains a major obstacle to effective antiviral treatment.Understanding the molecular mechanisms regulating HBV cccDNA transcription is essential for developing novel therapeutic strategies.In this study,we investigated the role of RNA binding motif protein 25(RBM25)in HBV replication,focusing on its interaction with cccDNA and its regulation of host transcription factors.The results demonstrated that RBM25 knockdown markedly inhibited HBV replication,reducing levels of HBV DNA,hepatitis B e antigen(HBeAg),hepatitis B surface antigen(HBsAg),HBV RNA,and L-HBs in HBV-replicating and infected cell models.Consistent results were observed in a mouse model hydrodynamically injected with 1.2HBV plasmid.Conversely,RBM25 overexpression significantly enhanced HBV replication.Mechanistically,RBM25 promoted HBV promoter activities by binding to cccDNA through its RE/RD and PWI domains.This effect was mediated by increased Yin Yang 1(YY1)expression,which enhanced acetylation of cccDNA-bound histones,promoting HBV transcription.Furthermore,RBM25 expression was upregulated and translocated to the nucleus following core protein expression and accumulation,while overexpression of RBM25 promoted core protein degradation.In conclusion,this study demonstrates that RBM25 is a novel host factor that enhances HBV replication by upregulating YY1-dependent transcriptional activation of cccDNA.It also reveales a reciprocal regulatory mechanism between the HBV core protein and RBM25,which helps sustain HBV replication.
文摘In this paper, in Section 1, we have described some equations and theorems concerning the Lebesgue integral and the Lebesgue measure. In Section 2, we have described the possible mathematical applications, of Lebesgue integration, in some equations concerning various sectors of Chern-Simons theory and Yang-Mills gauge theory, precisely the two dimensional quantum Yang-Mills theory. In conclusion, in Section 3, we have described also the possible mathematical connections with some sectors of String Theory and Number Theory, principally with some equations concerning the Ramanujan’s modular equations that are related to the physical vibrations of the bosonic strings and of the superstrings, some Ramanujan’s identities concerning π and the zeta strings.
