KLF4 (Kruppel-like factor 4 (gut))

KLF 4 ( Kruppel - like factor 4 ( gut ) )

A full-length mouse cDNA clone encoding KLF4 was initially isolated from a NIH3T3 cDNA library by reduced stringency screening with a DNA probe containing the zinc finger region of an immediate early gene product, Zif268 or Egr1. A distinct feature of the KLF4 gene is the highly GC-rich nature of the sequence near its 5'-end. Thus, the G+C content of the 1000 nt 5'-flanking region is 67% and th...

Ectopic expression of kruppel like factor 4 (Klf4) accelerates formation of the epidermal permeability barrier.

Dysfunction of the epidermal permeability barrier can result in dehydration, electrolyte imbalance and poor thermoregulation. Immature skin is a portal of entry for infectious agents and potential toxins in topically applied substances. As the skin is one of the last organs to mature in utero, premature infants born before 34 weeks gestation are at great risk for complications. The transcriptio...

Kruppel - like factor 4 ( KLF 4 ) and cancer literatures

Kruppel-like factor 4 (KLF4) is a member of the KLF family of transcription factors and regulates proliferation, differentiation, apoptosis and somatic cell reprogramming. KLF4 is also a tumor suppressor in certain cancers. KLF4 can be an indicator of stem-like capacity in embryonic stem cells (ESCs) and mesenchymal stem cells (MSCs), etc. The KLF4 gene is conserved in chimpanzee, Rhesus monkey...

Kruppel-like factor 4 (KLF4) represses histidine decarboxylase gene expression through an upstream Sp1 site and downstream gastrin responsive elements.

Histidine decarboxylase (HDC) is the enzyme that catalyzes the conversion of histidine to histamine, a bioamine that plays an important role in allergic responses, inflammation, neurotransmission, and gastric acid secretion. Previously, we demonstrated that gastrin activates HDC promoter activity in a gastric cancer (AGS-E) cell line through three overlapping downstream promoter elements. In th...
