Mouse P‑Cadherin Antibody

Detection of P‑Cadherin in Human Liver.

P‑Cadherin was detected in immersion fixed paraffin-embedded sections of human liver using Goat Anti-Mouse P‑Cadherin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF761) at 0.5 µg/ml for 1 hour at room temperature followed by incubation with the Anti-Goat IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC004). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to the cell membrane of hepatocytes.

Detection of Mouse P‑Cadherin by Simple Western^TM.

Simple Western lane view shows lysates of mouse embryo tissue, loaded at 0.2 mg/mL. A specific band was detected for P-Cadherin at approximately 115 kDa (as indicated) using 25 µg/mL of Goat Anti-Mouse P-Cadherin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF761) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Additional analysis of epidermal perturbations upon Mettl3 cKO. (F) Representative images of P0 back skin sagittal sections with cleaved Caspase-3 immunostaining&TUNEL staining (scale bars: 20 µm). White solid lines indicate skin surface&dashed lines indicate dermal-epithelial border. Quantification of TUNEL+&cleaved Caspase-3+ cells in the designated layers at P0. Only double-positive cells denote apoptosis; TUNEL+ only cells are typically seen as granular cells lose their nuclei&transition as dead flattened cells to the stratum corneum. This is defective in Mettl3 cKO skin. The TUNEL+ cells in the suprabasal 1 layer likely correspond to the occasional cytolytic suprabasal cells that we saw at the ultrastructural level (not shown). Quantification of the labeled cells is shown (error bars: standard deviation, for each condition n = 3 biological replicates × 10 images per replicate, *p<0.05 and **p<0.01 by unpaired two-tailed Student’s t-test).Figure 6—figure supplement 2—source data 1.Quantification of PCAD, ECAD immunofluorescence signals in (A).Figure 6—figure supplement 2—source data 2.Quantification of EdU+ cells&the suprabasal/basal cell number ratio in (B).Figure 6—figure supplement 2—source data 3.Quantification of cell sizes by cytospin in (C).Figure 6—figure supplement 2—source data 4.Quantification of cell death events in epidermis in (F).Quantification of PCAD, ECAD immunofluorescence signals in (A).Quantification of EdU+ cells&the suprabasal/basal cell number ratio in (B).Quantification of cell sizes by cytospin in (C).Quantification of cell death events in epidermis in (F).

Additional analysis of features affected by the upregulated genes upon Mettl3 cKO.(A) ECDF plots of the Z score (cKO/Ctrl) from scRNA-seq demonstrate transcripts with higher levels of m6A modification (assessed by the coding sequence SN-uTPM per nt value from miCLIP) in wild-type tend to be more upregulated upon METTL3 loss. The p values were calculated through Wilcoxon rank sum test. (B, C) Violin plots illustrating the relative expression levels of Bmyc and Myc mRNA in corresponding groups of Mettl3 cKO versus control cells. Z score assessment of expressional difference between cKO and control [Z (cKO/Ctrl)] and false discovery rate (FDR) is calculated by MAST. The upregulation is verified with qPCR on total RNA samples extracted from YFP+ skin epithelial cells FACS isolated from E16.5 embryos with Tbp mRNA as internal control (error bars: standard deviation, for each condition n = 3 biological replicates, **p<0.01 by unpaired two-tailed Student’s t-test). (D) Images from E17.5 and P0 sagittal sections immunolabeled for MYC and PCAD (scale bars: 25 µm). White solid lines denote skin surface and dashed lines denote dermal:epidermal border.
