[Research progress of Krüppel-like factor 7].

Krüppel-like factor 7 (KLF7), a member of Krüppel-like transcription factors (KLFs), also known as ubiquitous Krüppel- like factor (UKLF), is ubiquitously expressed in various tissues of adult human beings. Genetics reports showed that the genetic polymorphism of KLF7 is associated with obesity, type 2 diabetes, mental development in human beings; and KLF7 methylation is associated with the development of diffuse gastric cancer (gastric adenocarcinoma). In addition, some genomics reports suggested that KLF7 is one of the key transcription factors in the regulatory networks of serum markers change during the cardiovascular disease. The function studies showed that KLF7 is involved in the regulation of the development and function of the nervous system and adipose tissue, type 2 diabetes, blood diseases, as well as pluripotent cells maintenance. This review summarizes the research progress of KLF7 in genetic characteristics, protein structure and gene function.
