2. Differential Gene Expression Analysis
Volcano plot of simulated differential expression for target genes. Yellow labels indicate genes directly targeted by generated hypotheses.
# Differential gene expression volcano plot # Target genes: HSP90AA1, TREM2, VCP, LRP1, CHMP4B, SNAP25, NLGN1 np.random.seed(42) # [500 genes simulated with target genes as significantly DE]
Total genes: 500 Significantly up (FC>1, p<0.01): 6 Significantly down (FC<-1, p<0.01): 8 Target genes: HSP90AA1, TREM2, VCP, LRP1, CHMP4B, SNAP25, NLGN1
