The MD–SLE shared core program

Methods in brief / 方法概要

Program definition. Direction-consistent differentially expressed genes shared by the MD discovery cohort (GSE202657, 9 vs 9) and the SLE discovery cohort (GSE50772, 61 vs 20; limma, adj. P < 0.05 and |logFC| > 0.585 in both) define the 123-gene shared set; grading by independent-cohort direction replication (T0 = all three layers, 13 genes; T1 = two, 52; T2 = one, 40; T3 = none, 18) and bootstrap stability selection define the locked 65-gene core program (36 up, 29 down).
程序定义:MD 发现队列(GSE202657,9/9)与 SLE 发现队列(GSE50772,61/20)中方向一致的差异基因构成 123 基因共享集(两病均 limma adj. P<0.05 且 |logFC|>0.585);按独立队列方向复现层数分级(T0 三层 13 个、T1 两层 52、T2 一层 40、T3 零层 18),经自助稳定性选择锁定 65 基因核心程序(上调 36、下调 29)。

Locked-formula scoring. Per-sample ssGSEA scores (GSVA v2) for the up and down arms, computed separately, unchanged in every cohort. Cohort statistic: S = Cliff's δ(up) − Cliff's δ(down) with 10,000 label permutations. Declared input transforms: arrays as deposited; counts as log2(CPM+1); RPKM as log2(x+1).
锁定公式打分:逐样本 ssGSEA(GSVA v2)分别计算上调臂与下调臂,所有队列不作任何改动。队列统计量 S = Cliff's δ(上调)− Cliff's δ(下调),10,000 次标签置换。预先声明的输入变换:芯片用提交值;计数用 log2(CPM+1);RPKM 用 log2(x+1)。

Evidence layers. Single-cell localisation: donor-level pseudobulk of the CELLxGENE lupus atlas (program strongest in the myeloid/DC axis; cDC per-gene concordance 55/65). Communication: CellChat — no program gene is a ligand/receptor in SLE; NAMPT (VISFATIN) is the sole MD exception. Perturbation: CellOracle and scTenifoldKnk on upstream regulators (see target table); Geneformer in-silico deletion in SLE classical monocytes — Impact_component_percent: CEBPB 40.28%, TNFAIP3 35.65%, STAT1 28.71% (highest for CEBPB; see the target cards for the full-precision values).
证据层:单细胞定位——CELLxGENE 狼疮图谱供体级伪 bulk,程序最强于髓系/DC 轴(cDC 逐基因一致 55/65)。细胞通讯——CellChat 显示 SLE 中无程序基因作配体/受体,MD 中仅 NAMPT(VISFATIN)例外。扰动——CellOracle 与 scTenifoldKnk 作用于上游调控因子(见靶点表);Geneformer 虚拟敲除(SLE 经典单核细胞)——Impact_component_percent:CEBPB 40.28%、TNFAIP3 35.65%、STAT1 28.71%(CEBPB 最高;完整精度数值见各靶点卡片)。

Reading the numbers. In the evidence matrix, NA means “not tested under the pre-specified design”, never “tested and negative”. Overlap statistics on the Analyze page are descriptive research aids, not diagnostics.
读数规则:证据矩阵中 NA 表示“按预先设计未测”,不是“测了为阴性”。“算”页面的重叠统计是描述性研究辅助,不是诊断工具。
