doi: 10.64898/2026.01.27.701991

Figure Lengend Snippet: (A) Schematic of a sagittal view of the zebrafish brain highlighting the proximate location of the diencephalic posterior tubercular nucleus (PTN) and innervation of the Mauthner cells (M-cell). (B) Confocal projections of PCNA expression in a representative communal, dominant, and subordinate Tg( dat :egfp) zebrafish. Merged channel also shows DAPI nuclear staining in blue. Arrowheads point to PCNA expressing PTN somata. Scale bar = 20 μm. (C) Summary graph of the fraction of PTN neurons that express PCNA. Symbols represent individual samples; bars represent averages, error bars represent SEM. Dashed lines show pairwise comparison connecting each dominant to its subordinate counterpart. (Com n=6, Dom n= 8, Sub n= 8; One-way ANOVA, P=0.0029 , One-way ANOVA, Tukey’s Multiple Comparison post-test).

Article Snippet: Another series of PBS washes (3-4 times for 5 minutes each) was performed, and slices were stained with a rabbit polyclonal anti-PCNA primary antibody (Cell Signaling, 2586t) at a concentration of 1:500.

Figure Lengend Snippet: (A) PC1 and PC2 are the first and the second principal components excluding social isolates. (B) Eigenvalues of the principal components excluding social isolates showing the percentage of variation explained by each component. Line plot illustrates the cumulative explained variance. (C) PC1 and PC2 are the first and the second Principal components excluding PCNA as a component. (D) Eigenvalues of the principal components excluding PNCA as a component showing the percentage of variation explained by each component. Line plot illustrates the cumulative explained variance. In A and C, points represent individual samples (n= 6 per social condition), different colors and symbols represent different groups. Ellipses represent 68% confidence intervals of core regions. Loading vectors represent original variables, the directions of arrows represent correlation between original variable and principal components, lengths represent association of original data to principal components. In B and D components are listed in descending order (highest to the lowest).

Article Title: The CD300c antibody CL7 suppresses tumor growth by regulating the tumor microenvironment in non-small cell lung carcinoma

doi: 10.3389/fonc.2025.1698857

Figure Lengend Snippet: CL7 reduces NSCLC cancer cell proliferation. IHC images and quantitative analyses were performed using the 10 mg/kg CL7 group, which served as the representative dose for downstream experiments. Immunohistochemistry analysis for proliferating cell nuclear antigen (PCNA), a marker of cell proliferation, was performed on lung tissue sections from tumor-bearing mice (n = 6 per group). Images were acquired using a light microscope at 20× magnification. Three random fields were selected, and PCNA-positive cells were quantified using QuPath software. All data are presented as mean ± SEM. *p < 0.05 versus PBS group.

Article Snippet: The sections were then incubated overnight at 4°C with a rabbit polyclonal anti-PCNA antibody (1:200, Santa Cruz Biotechnology, Dallas, TX, USA).
