Article Title: Success of GDNF-based treatment of Hirschsprung disease depends on NCAM1 signaling and various subtypes of enteric neural progenitors

doi: 10.1101/2025.05.23.655388

Figure Lengend Snippet: a. Feature plots showing the relative gene expression levels of signaling ( Ret and Ncam1 ) and binding ( Gfra1, Gfra2, Gfra3, Gfra4 ) GDNF receptors in the scRNA-seq dataset of GDNF-treated Hol Tg/Tg ;G4-RFP mice. b. Immunofluorescence staining of NCAM1 and its downstream signaling effector phospho-FAK[Y397] in the distal colon of Hol Tg/Tg mice at the indicated time points before, during and after GDNF treatment (representative images of N=3 animals per time point). c. Immunofluorescence staining of HuC/D and SOX10 in the distal colon of P8 Hol Tg/Tg mice that were administered GDNF enemas and were also injected with selective inhibitors (or vehicle only) for phospho-FAK[Y397] (PF-562271) or phosphoRET[Y1062] (BLU-667) from P4 onwards. Quantitative analysis of the number of HuC/D+ neurons per mm 2 is shown on the right, with each value corresponding to a microscopic field of view (7 to 10 fields of view per animal; N indicates the number of animals per group; n indicates the total number of counted cells). **** P < 0.0001; Ordinary one-way ANOVA with post-hoc Tukey’s test. The dashed outlines in panels b-c highlight either extrinsic nerve fibers or an individual ganglion. Scale bar, 25 μm (b) and 150 μm (c).

Article Snippet: Phospho-FAK[Y397] and phospho-RET[Y1062] inhibitors, PF-562271 (MedChemExpress Cat.# HY-10459) and Pralsetinib/BLU-667 (MedChemExpress Cat.# HY-112301), respectively, were similarly administered via daily intraperitoneal injections using the same 30mg/kg concentration (in a vehicle solution of 2% DMSO; 25% PEG 300; 5% Tween 80; 68% Saline), but in this case only during the GDNF treatment period (P4-P8).

Article Title: The oncolytic avian reovirus p17 protein suppresses invadopodia formation via disruption of TKs5 complexes and oncogenic signaling pathways

doi: 10.3389/fcimb.2025.1603124

Figure Lengend Snippet: The ARV p17 protein promotes PTEN expression in HeLa and A549 cells and inhibits FAK phosphorylation at Y397. (A) The expression levels of PTEN, phosphorylated FAK (p-FAK Y397), and total FAK were analyzed in p17-transfected cancer cells and untreated control cells. Whole-cell lysates were collected at 0, 6, 12, 18, and 24 hours post-transfection, followed by Western blot analysis. β-actin was used as a loading control. The fold changes in activation and inactivation indicated below each lane, were normalized against those in the mock-transfected cells. Protein levels in the mock group were set as 1-fold for comparison. (B) Signals for all blots were quantified using ImageJ software. Data in panel A are means and SE from three independent experiments.

Article Title: Tbx1 plays a critical role in focal adhesion dynamics through paxillin regulation.

doi: 10.26508/lsa.202403151

Figure Lengend Snippet: Figure 1. FA dynamics are altered in Tbx1-depleted cells. (A) Graphs showing the quantification of FA assembly and/or disassembly rate of Tbx1-depleted cells (Tbx1KD) or control cells (NT). (B) Photographs of frames obtained from time-lapse spinning confocal video microscopy movies. Indicated are some of the specific frames that were analysed to assess the number of forming or disassembling FA (arrows) in the lamellipodium of migrating cells, which were transfected with a construct encoding vinculin–GFP fusion protein to mark FAs. (C) Graph showing the number of unstable FA/cell normalized for total FA (FA remaining for less than 30 min). (D) Total Rac1 activity in collagen-stimulated cells was evaluated by the GST-RBD pull-down assay. The levels of total Rac1 or active Rac1 pulled down by GST-RBD analysed by immunoblotting with anti-Rac1 antibody. GAPDH was used as a loading control. (E) ECM-stimulated cells were analysed for the P-FAK (residues Y397 or Y925) and P-ERK1/2 levels by immunoblotting with specific antibody. GAPDH was used as a loading control. Graphs represent quantitative densitometric analysis from at least three experiments (right panels). N = 3 biological replicates. The scale bar represents 10 μm. *P < 0.05, **P < 0.01.

Data in (A) and (C) were analyzed using mixed effects analysis, including a random subject effect (mouse) and fixed effects of stimulation (insulin) and condition (FAKi). Interaction effects of insulin and FAK inhibitor (FAKi × Insulin) were evaluated. (D) was analyzed using a repeated‐measures two‐way ANOVA. The effects of insulin, FAKi, and FAKi × Insulin were investigated. Bonferroni multiple comparison adjustment ( α = 0.05) was used in the post hoc analysis of (A, C, and D). Insulin‐stimulated conditions are displayed in blue. The glucose uptake outcome in (C) was log‐transformed for statistical analysis.
