KLF4 signaling pathway

Based on Luminex technology platform, Creative Proteomics provides analysis services for key targets of KLF4 signaling pathway.

Kruppel-Like Factors (KLFs) are a family of transcription factors with zinc finger structure, which are involved in the regulation of several physiological activities and play a key role in apoptosis, differentiation, proliferation and embryonic development, and are closely related to eukaryotic gene transcriptional regulation.KLF4 is also known as gastrointestinal enriched Kruppel-like factor (GKLF) or epidermal zinc finger factor (EZF), Kruppel-like factor 4 (KLF4), as an important member of the KLFs family, shows high expression in primary hepatocellular carcinoma tissues, and KLF4 plays an important role in the biological function of primary hepatocellular carcinoma.

KLF4 signaling pathway Detection ServiceKLF4 protein is commonly expressed in the gastrointestinal epithelium, and the human KLF4 gene was cloned for the first time in 1998.KLF4 has a DNA-binding structural domain at the carboxyl terminus containing three C2H2 zinc finger structures, formed by 81 highly conserved amino acids, and has a high affinity for the GC box or CACCC element, which mainly recognizes and binds GC-rich DNA in the promoter region of target genes sequences. The amino terminus of KLF4 contains a highly variable transcriptional regulatory structural domain, containing a transcriptional activation structural domain between amino acid residues 91 and 117, rich in proline and serine, and a transcriptional repression structural domain between amino acid residues 181 and 388, rich in proline, indicating that KLF4 has two modes of activating and repressing gene transcription and plays different transcriptional regulatory function.

KLF4 can act as a putative tumor suppressor and transcription factor. The clinical significance, biological effects and mechanisms of KLF4 signaling in pancreatic cancer cells are highlighted by its important role in the effects of aerobic glycolysis in pancreatic tumors. Furthermore, the potential mechanisms of altered KLF4 expression and its effects on aerobic glycolysis in pancreatic cancer cells were found to be negatively correlated with KLF4 and LDHA expression in pancreatic cancer cells and tissues, and their expression correlated with the clinicopathological features of pancreatic cancer. Thus, dysregulated signaling in this novel KLF4/LDHA pathway significantly affects aerobic glycolysis and its development and progression in pancreatic cancer.

Technology platform:

We provide Luminex technology for KLF4 signaling pathway analysis.

Luminex technology is a multifunctional liquid phase analysis platform, mainly based on laser technology, colored microspheres, high-speed digital, and applied fluidics signal processing technology. Its core is the use of fluorescent dyes to encode polypropylene microspheres or magnetic microspheres. By adjusting the different mixing ratios of different fluorescent dyes, more than 100 microspheres with different fluorescence spectra are obtained. Perform a variety of hybridization reactions on microspheres with different fluorescent codes, such as antigen-antibody, enzyme-substrate, ligand-receptor binding reaction, and nucleic acid hybridization. Use laser detection to perform quantitative and qualitative analysis of microsphere encoding and reporter fluorescence respectively.

KLF4 is a zinc-finger transcription factor that is expressed in a variety of tissues including intestinal epithelium and skin and plays an important role in differentiation and cell cycle arrest. Depending on the gene targeted, KLF4 can activate and repress transcription. In addition, in certain cellular settings, KLF4 can act as an oncogene or tumor suppressor gene.

In addition to Luminex multiplex assay, enzyme-linked immunosorbent assay (ELISA), flow cytometry (FACS analysis) technology can also be provided to meet other customer needs.
