Figure Lengend Snippet: HNRNPA1 mediated the selective loading of hsa-miR-423-5p in HExs. A . The catRAPID website predicted RNA-binding proteins that could interact with hsa-miR-423-5p. B . HNRNPA1 expression was detected by Western blotting in Huh7 and 97H cells cultured under normoxic or hypoxic conditions. C . RNA pull-down experiments were performed using the miR-423-5p probe to isolate RNA-binding proteins, and the expression level of HNRNPA1 was subsequently assessed by Western blot analysis. D . RIP experiments were performed using an HNRNPA1-specific antibody to pull down miRNAs, and the expression level of hsa-miR-423-5p was subsequently measured by RT‒qPCR. E . Huh7 and 97H cells were infected with a specific knockdown lentivirus (sh-HNRNPA1) or a control lentivirus (sh-NC). The knockdown efficiency of sh-HNRNPA1 on HNRNPA1 was assessed by Western blotting. F . Cells were collected after infection with a lentivirus, along with their secreted exosomes. The expression levels of hsa-miR-423-5p in both cells and exosomes were measured by qRT-PCR (* p < 0.05, ** p < 0.01, *** p < 0.001)

Article Title: Ubiquitin-dependent proteasomal degradation of small hepatitis B virus surface antigen mediated by TRIM21 and antagonized by OTUD4

doi: 10.1128/jvi.02309-24

Figure Lengend Snippet: OTUD4 and TRIM21 alter the production of subviral particles and virions. (A, B, E, F) Lysates were prepared from Huh7 and HepG2 cells co-transfected with plasmids encoding 1.2HBV and either TRIM21-myc ( A, B ) or OTUD4-myc ( E, F ). These lysates were subjected to immunoblotting using antibodies against myc, β-actin, and SHBs, and intracellular HBV DNA levels were quantified by qPCR. Additionally, cell culture supernatants were analyzed by qPCR to quantify extracellular HBV DNA and virion DNA levels. (C, D, G, H) Lysates from cells transfected with plasmids encoding 1.2HBV and siRNA targeting either TRIM21 ( C, D ) or OTUD4 ( G, H ) were similarly processed. The lysates were immunoblotted using the indicated antibodies, and intracellular HBV DNA was quantified by qPCR. qPCR was performed on the supernatants to measure HBV DNA and virion DNA levels.
