In neural tissues, it promotes axonal outgrowth and regeneration by activating key growth‐promoting genes (such as TrkA, p21, and adhesion molecule–encoding genes) and by overcoming the developmental decline in intrinsic regenerative ability. Loss or downregulation of KLF7 leads to impaired neurite extension, deficits in sensory neuron survival, and misprojection of axons in several systems including the olfactory, visual, and cortical pathways. Studies using gene therapy strategies and chimeric activators further demonstrate that increasing KLF7 activity enhances axon regeneration in both central and peripheral nerve injuries."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "1", "end_ref": "10"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nIn addition to its essential functions in neuronal development, KLF7 exerts critical influence in cancer biology and cellular metabolism.
