尤因肉瘤整合免疫治疗靶点图谱

A 38-gene set was analyzed, including ESS32 and six comparator antigens (STEAP1, LINGO1, PRAME, CD99, CD276/B7-H3, and ENPP1). Eight Gene Expression Omnibus datasets ( n =854 samples) were assigned predefined roles spanning tumor- versus -skeletal-muscle comparison, broad normal-organ context, EWSR1::FLI1 perturbation, tumor-only support cohorts, cell-line models, and cross-sarcoma comparison. Results were overlaid with Human Protein Atlas and published proteomic/surfaceome evidence.

In GSE17674, the strongest tumor-enriched transcripts included NKX2-2, NPY1R, STEAP1, RBM11, RNF182, LIPI, CD99, STEAP2, LOXHD1, and DCDC2. Normal-tissue and compartment data substantially reordered RNA-only ranking. NKX2-2 showed the strongest Ewing-associated signal but encodes a nuclear transcription factor, favoring peptide-HLA/T-cell receptor (TCR) or vaccine development. RBM11 and LIPI emerged as high-interest intracellular/secretome-associated candidates, with an explicit epididymal/male reproductive caveat for LIPI. CD99 and NPY1R illustrated normal-cell reservoir and receptor-distribution constraints.

ESS32 should be interpreted as an EWSR1::FLI1-associated RNA discovery set, not as a pre-validated target panel. Practical nomination requires integration of RNA enrichment, normal-tissue distribution, protein evidence, cellular compartment, and modality compatibility before nomination of TCR, vaccine, antibody-drug conjugate (ADC), chimeric antigen receptor (CAR), radioligand, or validation-first candidates.
