Krüppel-like factor 5 promotes lung tumorigenesis through upregulation of Sox4.

BACKGROUND Krüppel-like factor 5 (KLF5), a member of zinc finger class of DNA-binding transcriptional regulators, has attracted attention because of its important regulatory activities linked to diverse functions such as cell growth, proliferation, differentiation, apoptosis and tumorigenesis in a number of systems. However, its biological functions in the initiation and progression of lung tum...

Krüppel-Like Factor 5 Mediates Proinflammatory Cytokine Expression in Lipopolysaccharide-Induced Acute Lung Injury through Upregulation of Nuclear Factor-κB Phosphorylation In Vitro and In Vivo

Acute lung injury (ALI) is associated with an inflammation-mediated process, and the transcription factor, Krüppel-like factor 5 (KLF5), might play a crucial role in inflammatory lung disease. In this study, we evaluated KLF5, reactive oxygen species (ROS), and inflammatory responses in a lipopolysaccharide- (LPS-) induced ALI model to elucidate the role of KLF5 in ALI. Our data indicated that ...

Opposing effects of Krüppel-like factor 4 (gut-enriched Krüppel-like factor) and Krüppel-like factor 5 (intestinal-enriched Krüppel-like factor) on the promoter of the Krüppel-like factor 4 gene

KLF4 (Krüppel-like factor 4 or gut-enriched Krüppel-like factor, GKLF) and KLF5 (Krüppel-like factor 5 or intestinal-enriched Krüppel-like factor, IKLF) are two closely related members of the zinc finger-containing Krüppel-like factor family of transcription factors. Although both genes are expressed in the intestinal epithelium, their distributions are different: Klf4 is primarily expressed in...

Krüppel-like factor 2 suppresses human gastric tumorigenesis through inhibiting PTEN/AKT signaling

Krüppel-like factors (KLFs) are a large family of DNA-binding transcriptional regulators that affect basic cellular processes such as growth, survival, migration and differentiation and serve a complicated function in cancers. KLF2, one member of the KLF family, is dysregulated in many tumors. However, the specific role of KLF2 in human gastric tumorigenesis is unknown. Here we show that the ex...

Krüppel-Like Factor 12 Promotes Colorectal Cancer Growth through Early Growth Response Protein 1

Krüppel-like factor 12 (KLF12) is a transcription factor that plays a role in normal kidney development and repression of decidualization. KLF12 is frequently elevated in esophageal adenocarcinoma and has been reported to promote gastric cancer progression. Here, we examined the role of KLF12 in colorectal cancer (CRC). Indeed, KLF12 promotes tumor growth by directly activating early growth res...
