Figure Lengend Snippet: IRX4 Expression is Significantly Downregulated in CRC. (A, B) Immunofluorescence staining of IRX4 (red) and the cell nucleus (blue), showing that IRX4 is primarily localized in the nucleus, with significantly reduced average fluorescence intensity in CRC cells compared to normal intestinal epithelial cells. Scale bar: 50 μm. (C, D) Protein expression of IRX4 in CRC tissues and adjacent normal tissues with statistical analysis. (E, F) Proin expression of IRX4 in CRC cells and normal intestinal epithelial cells. (G) RT-qPCR analysis of IRX4 expression in CRC tissues and corresponding adjacent normal tissues.

Figure Lengend Snippet: NVP-HSP990 significantly inhibited RV replication, viral gene transcription, and antigen expression. ( A ) Caco-2 cells were infected with RV (Wa or SA11 strains) at varying MOIs (0.001–10), followed by treatment with 100 nM NVP-HSP990 or an equal volume of DMSO (as a control) for 24 h. Viral replication was assessed using PFA. ( B ) Schematic diagram illustrating the timing of NVP-HSP990 addition and removal. ( C ) Caco-2 cells were infected with RV (MOI = 1) and treated with 100 nM NVP-HSP990 or with DMSO as control at indicated infection periods as shown in panel B. Viral replication was tested with PFA at 20 h p.i. ( D ) Caco-2 cells were infected with RV (MOI = 1) and treated with 100 nM HSP990 at 0, 4, 8, 12 h p.i. or treated with DMSO at 0 h p.i. Virus replication was tested with PFA at 24 h p.i. ( E ) Caco-2 cells were infected with RV (MOI = 1) and further cultivated with DMEM containing 100 nM NVP-HSP990 or DMSO as control for 18 h. Then the infected cells were harvested for qPCR analysis of the expression of RV genes encoding the VP2, VP6, NSP4, and NSP5 proteins. ( F ) Caco-2 cells were mock-infected with PBS or infected with RV (MOI = 1) and further cultivated with DMEM containing 100 nM NVP-HSP990 or DMSO as control for 18 h. Then the cells were harvested for WB analysis of RV structural proteins VP6 and VP7. ( G ) Caco-2 cells growing on coverslips were mock-infected with PBS or infected with RV (MOI = 3) and treated with 100 nM NVP-HSP990 or DMSO as control for 18 h. Then the infected cells were subjected to immunostaining of RV VP6 antigens (red). Data are presented as mean ± SEM ( A, C, D, E ). The experiments were performed in triplicate ( A, C, D, E ), and the data are representative of two independent experiments ( A, C–G ). ns, not significant; ** P < 0.01, *** P < 0.001, **** P < 0.0001 (two-way ANOVA [ A, C, E ] and one-way ANOVA [ D ]).

Figure Lengend Snippet: NVP-HSP990 inhibited MAPK activation and facilitated expression of tight junction-associated proteins in intestinal cells. ( A ) MA104, Caco-2, and HT-29 cells were mock-infected with PBS or infected with RV Wa or SA11 strains (MOI = 3), followed by treatment of 100 nM HSP990 (+) or an equal volume of DMSO as a control (−) for 20 h. Then the infected cells were harvested for WB analysis of MAPK components. ( B ) Caco-2 cells were mock-infected with PBS, treated with 1 µM C16-PAF(C16), or infected with RV Wa or SA11 strains (MOI = 3), and then treated with 100 nM HSP990 (+) or DMSO as a control (−) for 20 h. The infected cells were harvested for WB analysis of MAPK components. ( C ) Caco-2 cells were mock-infected with PBS or infected with RV Wa or SA11 strains (MOI = 3), and then treated with 100 nM HSP990 (+) or DMSO as control (−) for 20 h. Then the infected cells were harvested for WB analysis of tight junction-associated proteins. Data are representative of three ( A ) and two ( B and C ) independent experiments.

Figure Lengend Snippet: NVP-HSP990 mitigated disruption of tight junctions in RV infection. Caco-2 cells growing on coverslips were mock-infected or infected with RV Wa or SA11 strains (MOI = 3), and cultivated with DMEM containing 100 nM NVP-HSP990 or an equal volume of DMSO as a control after infection for another 18 h. Then the infected cells were applied for immunostaining for RV antigens (green), ZO-1 (red), and DAPI staining of nucleus (blue). Data are representative of two independent experiments.
