Article Title: JAK-centric explainable few-shot gene-expression diagnosis framework for alopecia via MultiPLIER priors and relation-style set-to-set comparison

doi: 10.3389/fmolb.2025.1753206

Figure Lengend Snippet: RT-qPCR validation of the IL2RB/IL2RG–EOMES–GZMA cytotoxic/JAK axis in alopecia areata (AA). Relative mRNA levels of EOMES, GZMA, IL2RB, and IL2RG are significantly elevated in AA lesional scalp compared with healthy controls, whereas androgenetic alopecia (AGA) samples are comparable to controls, indicating that this cytotoxic/JAK module is transcriptionally active in AA but largely quiescent in AGA. Data are shown as mean ± SD. Statistical annotations: ** p < 0.01 vs. control; n.s., not significant (AGA vs. control).

Article Snippet: Equal amounts of protein were resolved by SDS–PAGE and transferred to PVDF membranes at 200 mA for 2 h. Membranes were blocked in 5% non-fat milk at room temperature for 2 h and incubated overnight at 4 ° C with primary antibodies against β -actin (1:4000; 20536-1-AP, Proteintech, China), EOMES (1:5000; 83945-5-RR, Proteintech, China), GZMA (1:500; 11288-1-AP, Proteintech, China), IL2RB (1:5000; 13602-1-AP, Proteintech, China), and IL2RG (1:500; 11409-1-AP, Proteintech, China).
