Article Title: Mutational order and epistasis determine the consequences of FBXW7 mutations during colorectal cancer evolution

doi: 10.1101/2023.08.25.554836

Figure Lengend Snippet: Characterisation of W and F organoids. a. Brightfield microscopy of W and F organoids revealed no observable phenotypic differences. Scale bars represent 500μm. b. Western blot validation showing loss of FBXW7 protein in F organoids. c. Immunofluorescence of W and F organoids with DAPI nuclear stain (blue), F-actin (red), FBXW7 (orange). Scale bars represent 100μm. d. FBXW7 targets the phosphorylated substrates and ubiquitinates these substrates for proteasomal degradation. This included phosphorylated cJun, phosphorylated CCNE1, phosphosylated cMyc, and notch intracellular domain (NICD). The non-phosphorylated substrates were affected to varying degrees. While upregulation of cJun, was observed, there was no change in the quantities of CCNE1, cMYC and NOTCH. e. Volcano plot from bulk RNAseq of F vs W organoids revealed minimal differential expression of genes. Only HLA-DQB1 was found to be significantly downregulated, and GSTM1 significantly upregulated in F organoids. All experiments were performed with N = 3 biological replicates.

Article Title: Podocyte-specific deletion of miR-146a increases podocyte injury and diabetic kidney disease

doi: 10.3389/fmed.2022.897188

Figure Lengend Snippet: Mechanistic model. A diagram showing a mechanistic working model. Podocyte expressed miR-146a represses expression of ErbB4 and Notch-1 during homeostatic conditions, thereby controlling the ErbB4/EGFR and TGFβ 1 signaling pathways. Various external stressors or deletion of miR-146a result in de-repression of ErbB4 and Notch-1, thereby driving the harmful ErbB4/EGFR signaling and inducing TGFβ 1. An autocrine feed-forward loop via TGFβ 1 induces the downstream TGFR/Smad3 signaling, that result in podocyte damage, glomerular injury and proteinuria.
