Figure Lengend Snippet: ( A ) Schematic of multi-omics analysis of scrambled control (CTRLi) and p63 knockdown (p63i) in SCC cell lines and normal undifferentiated and differentiated keratinocytes.

Undifferentiated keratinocytes (Undiff) and differentiated keratinocytes (Diff) are indicated. p63-related features in SCC cells compared to normal keratinocytes were classified into four classes: (i) SCC-specific, (ii) shared between SCC and undifferentiated keratinocytes (SCC & Undiff), (iii) shared between SCC and differentiated keratinocytes (SCC & Diff), and (iv) shared by SCC, undifferentiated, and differentiated keratinocytes (all common). ( C ) Peak-centered ChIP-seq heatmaps of four classes of p63 binding sites in SCC cells compared to normal keratinocytes and ATAC-seq heatmap corresponding to the ChIP-seq peaks. ( D ) Venn diagram comparing CAL27 and SCC13 cell line-specific p63 binding sites (permutation test). ( E ) Bar plot of distances between transcriptional start site (TSS) of potential target genes in the cell cycle pathway and common SCC cell line-specific p63 binding sites.

doi: 10.2147/CCID.S606845

Figure Lengend Snippet: Proposed workflow for exosome‑based clinical diagnostics in psoriasis. The workflow follows MISEV2023 guidelines and includes (1) sample collection (plasma, urine or tissue, processed on ice within 1 h); (2) EV separation (differential ultracentrifugation plus iodixanol density gradient); (3) orthogonal quality control (NTA, TEM, EV markers CD9/CD63/CD81/ALIX/TSG101, and exclusion of non‑EV contaminants such as calnexin); (4) molecular profiling (qRT‑PCR or ddPCR for exosomal miRNAs or mRNAs); and (5) clinical interpretation (ROC‑derived cut‑offs, composite scores with PASI/CRP, independent validation). No exosome‑based psoriasis test has yet received regulatory clearance.
