Network analysis of sperm storage tubules (SST) isolated at D7 and D30. The core analysis tool from Ingenuity Pathway Analysis (Qiagen, Valencia, CA) was used to biologically interpret differentially expressed genes (DEGs). Copyright permission from Qiagen has been obtained for use of the images presented. (A) The top network generated through pathway analysis of DEGs between D7 and D30 timepoints (network score = 48, top function = cell morphology) (FPKM > 1, q-value < 0.05, |fold change| > 1.5). (B) The top regulator effects network generated through pathway analysis of DEGs between D7 and D30 (consistency score = 2.041) (FPKM > 1, q-value < 0.05, |fold change| > 1.5).
