doi: 10.64898/2026.03.03.709360

Figure Lengend Snippet: (A-B) Volcano plots of whole-transcriptome differentially expressed genes (DEGs) identified by RNAseq in ST88-14 and NF90.8 cells following siRNA-mediated depletion of ZNF423 ( n =3) compared to control ( n =3). Dashed vertical lines reflect log 2 FC of −1 and 1. Dashed horizontal line reflects false discovery rate (FDR) of 0.05. Downregulated genes with log 2 FC≤-1 and -log 10 adjusted p-value above FDR threshold are denoted in blue. Upregulated genes log 2 FC≥1 and -log 10 adjusted p-value above FDR threshold are denoted in red. Raw RNAseq hit counts for ZNF423 in NF90.8 cells transfected with control siRNA ( n =3) or siZNF423 ( n =3). P-values represent unpaired, two-tailed t-tests between groups. (C) Venn diagram showing overlap of significantly downregulated DEGs common among ST88-14 and NF90.8 cell lines. Downregulated DEGs were defined as log 2 FC≥-1 and adjusted p-value of ≤0.05. (D) Dot plot of top enriched Hallmark gene signatures of shared downregulated genes (FDR≤0.05). (E) Venn diagram showing overlap of significantly upregulated DEGs common among ST88-14 and NF90.8 cell lines. Upregulated DEGs were defined as log 2 FC≥1 and adjusted p-value of ≤0.05. (F) Dot plot of top enriched Hallmark gene signatures of shared upregulated genes (FDR≤0.05). (G-H) Volcano plots of differentially expressed transcription factors and kinases in ST88-14 and NF90.8 cells following siRNA-mediated depletion of ZNF423 compared to control. (I-J) Immunoblots showing cleavage of PARP, ATF3, ATF4 and ZNF423 protein expression following siRNA-mediated depletion of ZNF423 ( n =3) compared to controls ( n =3). GAPDH serves as loading control. Protein expression was normalized to total protein and quantified using ImageJ. Error bars reflect SEM. P-values represent unpaired, two-tailed t test with Welch’s correction. ****=p-value ≤0.0001, ***=p-value≤0.001, **=p-value≤0.01, *=p-value≤0.05, ns=not significant.

Article Snippet: Immunoblots were performed using primary antibodies against ZNF423 (ABN410, Sigma-Aldrich), GAPDH (sc-365062, Santa Cruz Biotechnology), SUZ12 (3737S, Cell Signaling Technology), ATF3 (18665S, Cell Signaling Technology), ATF4 (11815S, Cell Signaling Technology), PARP (9542S, Cell Signaling Technology), and γH2A.x (9718S, Cell Signaling Technology).

Article Title: Remdesivir may exacerbate ischemic acute kidney injury through molecular alterations in PGC-1α and apoptosis pathways: An in vivo study

doi: 10.1371/journal.pone.0336221

Figure Lengend Snippet: The results of western blotting (A) . The protein levels of ATF3 (B) , p-p53 (C) , p-p21 (D) , and cas3 (E) were represented in the studied groups. β-actin was used as an internal control. cas3: caspase-3, ip: intraperitoneal, I/R: ischemia/reperfusion, NF-κB: nuclear factor kappa-light-chain-enhancer of activated B cells, Rem: Remdesivir, sc: subcutaneous.
