BDNF and cancer: In our study, we found some difference; e.g., three pathways for the regulation of actin cytoskeleton, endocytosis, and axon guidance all contained a high number of targeted genes in five lists; pathways for cancer and tight junctions are at the forefront of four lists, except for LLWF vs. BLWF; other pathways such as focal adhesion, the MAPK signaling pathway, cytokine-cytokine receptor interactions, the Wnt signaling pathway, and neurotrophin signaling pathway all played important roles in follicle development.
