doi: 10.1016/j.jare.2025.05.003

Figure Lengend Snippet: PEBL alleviates Poly(I:C)-induced ALI in a dose-dependent manner and modulates cytokine levels in macrophage inflammation. (A) Experimental design for PEBL treatment in ALI zebrafish. (B) Dose-dependent reduction in mortality by PEBL. Survival plot of 5 dpf Tg(coro1α: GFP) larvae at 72 hpi ( n = 30). (C) Dose-dependent reduction in macrophage recruitment by PEBL. Quantitative analysis of macrophage infiltration in the swim bladder section at 4 hpi ( n = 10). (D) Fluorescence images of macrophages in the swim bladder section at 4 hpi following different concentrations of PEBL, marked by the red circle. (E-J) PEBL reduces Poly(I:C)-induced cytokine elevation in RAW264.7 cells ( n = 3). mRNA levels of IL-1β, IL-6, and TNF-α in cells were measured by qPCR (E-G), while protein concentrations of these cytokines in culture media were quantified using ELISA (H-J). ## P < 0.01, ### P < 0.001 vs. Poly(I:C); ** P < 0.01, *** P < 0.001 for group comparisons.

Article Title: PEBL, a component-based Chinese medicine, reduces virus-induced acute lung injury by targeting FXR to decrease ACE2 levels

doi: 10.1016/j.jare.2025.05.003

Figure Lengend Snippet: PEBL suppresses Poly(I:C)-induced FXR and ACE2 expression and NF-κB-p65 nuclear translocation in RAW264.7 cells. (A-E) PEBL reduces the mRNA (A-B) and protein (D-E) levels of FXR and ACE2 and diminishes NF-κB-p65 nuclear translocation (C, E). (F-H) PEBL suppresses the protein distribution of FXR and ACE2, inhibits the nuclear translocation of NF-κB-p65. Representative images show the localization of FXR (F, green), ACE2 (G, green), NF-κB-p65 (H, green), and DAPI (blue), captured by immunofluorescence at 40 × magnification using confocal microscopy. Scale bar = 10 μm. UDCA was used as a positive control. Nuc, nucleus; Cyt, cytoplasm; Mem, membrane. n = 3; * P < 0.05, ** P < 0.01, *** P < 0.001 for group comparisons.

Article Title: PEBL, a component-based Chinese medicine, reduces virus-induced acute lung injury by targeting FXR to decrease ACE2 levels

doi: 10.1016/j.jare.2025.05.003

Figure Lengend Snippet: PEBL suppresses Poly(I:C)-induced FXR binding to ACE2 by inhibiting FXR transcription in RAW264.7 cells. (A-B) FXR overexpression reverses the effect of PEBL on the protein levels of ACE2 and NF-κB-p65. n = 3. (C-D) FXR overexpression reverses the inhibitory effect of PEBL on ACE2 distribution and NF-κB-p65 nuclear translocation. Representative images show the localization of ACE2 (C, green), NF-κB-p65 (D, green), and DAPI (blue), captured by immunofluorescence at 40 × magnification using confocal microscopy. Scale bar = 10 μm. (E-H) PEBL requires FXR to decrease ACE2 expression and mitigate Poly(I:C) infection. In FXR-KD cells (F, H), no significant change in ACE2 expression was observed following treatments with CDCA, Poly(I:C), UDCA, or PEBL, compared to WT cells (E, G). WT, wild-type RAW264.7 cells; n = 3. (I) Co-IP analysis reveals no binding between FXR and ACE2 proteins. (J-K) PEBL reduces Poly(I:C)-induced FXR binding to the ACE2 promoter, confirmed by ChIP-qPCR and agarose gel electrophoresis.Nuc, nucleus; Cyt, cytoplasm; Mem, membrane; OSTα, positive control; ACE2-NC, negative control; C, control; P, Poly(I:C). n = 6; * P < 0.05, ** P < 0.01, *** P < 0.001 for group comparisons; ns , non-significant.

Article Title: Antitumor effects of plasma-activated sodium acetate solution on gastric cancer cells

doi: 10.1038/s41598-025-04977-3

Figure Lengend Snippet: ( a ) The experimental system employed to produce plasma-activated liquids. L represents the distance between the plasma source and medium, and V represents the volume of the irradiated medium. In this experiment, L was fixed at 3 mm, and V at 6 ml. ( b ) Antitumor effects of PAL, PAA, 1% PASA, 3% PASA, and 5% PASA on GC cell lines. PASA had stronger antitumor effects at T = 0.5, 1, and 3 min compared with PAL. ( c ) Effects of PAL, PAA, 3% PASA, and 5% PASA on human peritoneal mesothelial cells. PAA and 3% PASA caused much less damage to normal peritoneal mesothelial cells compared with PAL. Error bars indicate standard deviation.

doi: 10.1038/s41598-025-04977-3

Figure Lengend Snippet: ( a ) Apoptosis assay of normal peritoneal mesothelial cells and GC cells treated with 3% PASA. The percentages of apoptotic plus dead MKN1-Luc and MKN45-Luc cells increased within T = 3 min. ( b ) Morphological change induced by 3% PASA treatment. Morphological changes in MKN45-Luc cells by treatment with 3% sodium acetate solutions without plasma exposure (control group) or 3% PASA for T = 10 min (treatment group) were observed using time-lapse photography. In the treatment group, numerous blebs, indicative of apoptosis, were observed around the cells (arrow).
