ABSTRACT
CCAAT enhancer binding protein β (C/EBPβ), as a nuclear transcription factor necessary for the development of liver, airway epithelium, and adipose tissue, plays a vital role in physiological processes related to cell proliferation, apoptosis, and differentiation. However, the up-regulation of C/EBPβ activates signal pathways related to inflammatory response, epithelial-mesenchymal transition, cell proliferation and invasion, immune response, and angiogenesis by regulating a series of downstream genes transcription promotes the development of lung diseases. Therefore, targeting C/EBPβ may be a potential treatment strategy for lung diseases. This paper summarizes the regulatory effects of C/EBPβ and related signaling pathways in lung infection, asthma, chronic obstructive pulmonary disease, lung injury, pulmonary fibrosis, and lung cancer to provide a theoretical basis for the precision medicine of lung diseases.
