BDNF and cancer: Three pathways are involved in regulation of the actin cytoskeleton, endocytosis, and axon guidance, which all contained a high number of targeted genes in the five lists; pathways in cancer and tight junctions are listed in 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 play important roles in follicle development.
