Krüppel-like factors in cancer
TLDR
The roles and regulation of the 17 known KLFs in various cancer-relevant processes are discussed, with some KLFs having different roles in normal cells and cancer, during cancer development and progression and in different cancer types.Abstract:
Kruppel-like factors (KLFs) are a family of DNA-binding transcriptional regulators with diverse and essential functions in a multitude of cellular processes, including proliferation, differentiation, migration, inflammation and pluripotency. In this Review, we discuss the roles and regulation of the 17 known KLFs in various cancer-relevant processes. Importantly, the functions of KLFs are context dependent, with some KLFs having different roles in normal cells and cancer, during cancer development and progression and in different cancer types. We also identify key questions for the field that are likely to lead to important new translational research and discoveries in cancer biology.read more

TL;DR: It is demonstrated that Klf9 independently causes increased ROS levels in various types of cultured cells and in mouse tissues and is required for pathogenesis of bleomycin-induced pulmonary fibrosis in mice and identified as a ubiquitous regulator of oxidative stress and lung injury.

TL;DR: It is reported that Ccm1 ablation leads to the activation of a MEKK3‐MEK5‐ERK5-MEF2 signaling axis that induces a strong increase in Kruppel‐like factor 4 (KLF4) in ECs in vivo, and this data unveil KLF4 as a therapeutic target for CCM.

TL;DR: CDNA microarray analysis of whole liver was compared and Pituitary tumor transforming gene 1 (PTTG1), an oncogene, was the most up‐regulated transcript in KLF6+/− liver, and PTTG1 downregulation represents a novel tumor suppressor pathway of KLF 6.

Effects of Kruppel-like factor 6 on osteosarcoma cell biological behavior
TL;DR: The results suggested that KLF6 could inhibit proliferation and invasion, and facilitate apoptosis of osteosarcoma cells, which might be a potential target for the treatment of fractures.

Vesnarinone, a differentiation inducing drug, directly activates p21(waf1) gene promoter via Sp1 sites in a human salivary gland cancer cell line.
TL;DR: The results suggest that vesnarinone directly activates p21waf1 promoter via the activation of Sp1 and Sp3 transcription factors and the histone hyperacetylation in TYS cells.
