摘  要:Kindlin-2 functions in the maintenance of homeostasis and in human diseases.This study investigated the interrelationship between Kindlin-2 expression in tissues and the corresponding germ layers from which these tissues originated.Kindlin-2 expression was examined in normal adult human organs and human cancer tissues by immunohistochemical analyses.Analysis of Kindlin-2 mRNA levels in adult human organs in the Oncomine dataset revealed Kindlin-2 is highly expressed in mesoderm-derived organs.However,Kindlin-2 was negative or weakly expressed in endoderm/ectoderm-derived organs.Interestingly,the abnormal expression of Kindlin-2 was observed in a variety of human cancers.In agreement with its expression profile in humans,Kindlin-2 was also highly expressed in mesoderm-derived organs in mouse embryos with the exception of strong Kindlin-2 expression in ectoderm-derived spinal cord and ganglia,tissues that are highly mobile during embryonic development.Importantly,we demonstrated the expression level of Kindlin-2 in adult organs correlated with their embryonic dermal origins and deregulation of Kindlin-2 in tissues is associated with tumor progression.This finding will help us understand the dual role of Kindlin-2 in the regulation of tumor progression and embryonic development.Kindlin-2 functions in the maintenance of homeostasis and in human diseases.This study investigated the interrelationship between Kindlin-2 expression in tissues and the corresponding germ layers from which these tissues originated.Kindlin-2 expression was examined in normal adult human organs and human cancer tissues by immunohistochemical analyses.Analysis of Kindlin-2 mRNA levels in adult human organs in the Oncomine dataset revealed Kindlin-2 is highly expressed in mesoderm-derived organs.However,Kindlin-2 was negative or weakly expressed in endoderm/ectoderm-derived organs.Interestingly,the abnormal expression of Kindlin-2 was observed in a variety of human cancers.In agreement with its expression profile in humans,Kindlin-2 was also highly expressed in mesoderm-derived organs in mouse embryos with the exception of strong Kindlin-2 expression in ectoderm-derived spinal cord and ganglia,tissues that are highly mobile during embryonic development.Importantly,we demonstrated the expression level of Kindlin-2 in adult organs correlated with their embryonic dermal origins and deregulation of Kindlin-2 in tissues is associated with tumor progression.This finding will help us understand the dual role of Kindlin-2 in the regulation of tumor progression and embryonic development.
