Figure Lengend Snippet: Identification of potential biomarkers in ATC/PDTC. A , volcano plot of DEPs in ATC/PDTC versus PTC with |log 2 FC| ≥ 1 and p < 0.05. B , correlation analysis of FCGR2A with NET formation markers PADI4 across groups. C , single-cell RNA-seq data ( GSE232237 ) showing FCGR2A expression predominantly in macrophages, with the highest expression in ATC. D , correlation analysis of FCGR2A expression with M0 macrophages, NK cells, and B cells examined by Spearman analysis. E , representative figures of IHC analysis validation of FCGR2A, UBE2C, and NUBPL expression in ATC (n = 11), PDTC (n = 7), and PTC (n = 10) tissues. The numbers at the upper left corner of each IHC image (0–3) indicate the immunoreactivity score for the representative case. The IHC scores were fully plotted in the bar plots assessed by pairwise student’s t tests. ns, not significant; ∗ p < 0.05; ∗∗∗ p < 0.001; and ∗∗∗∗ p < 0.0001. ATC, anaplastic thyroid carcinoma; FCGR2A, Fc fragment of IgG receptor IIa; IHC, immunohistochemistry; log 2 FC, log 2 fold change; NK, natural killer; PDTC, poorly differentiated thyroid carcinoma; PTC, papillary thyroid carcinoma; PADI4, peptidyl arginine deiminase 4; NUBPL, nucleotide-binding protein-like; UBE2C, ubiquitin-conjugating enzyme E2 C.
Article Snippet: Primary antibodies—including FCGR2A (RRID: AB_2246912 , Cat.15625-1-AP, Proteintech, 1:600 dilution), ubiquitin-conjugating enzyme E2 C (UBE2C) (RRID: AB_11232220 , Cat.66087-1-Ig, Proteintech, 1:500), and nucleotide-binding protein-like (NUBPL) (RRID: AB_2878402 , Cat.17393-1-AP, Proteintech, 1:200)—were diluted in antibody dilution buffer and applied to tissue sections.
