KRT18 encodes the Keratin 18 protein, also commonly known as cytokeratin - 18. Keratin 18 is an important intermediate - filament protein. It forms heterodimers with Keratin 8, providing mechanical stability to cells. This protein is involved in the PI3K - AKT signaling pathway, which regulates cell survival, proliferation, and apoptosis.
Altered expression of KRT18 has been associated with various diseases, including liver diseases and certain cancers. In cancer, elevated levels of KRT18 may indicate a poor prognosis. Regarding drug development, researchers are exploring targeting KRT18 - related pathways to design new therapies, although significant progress towards clinical application is still awaited.

IHC image of CSB-PA10629A0Rb diluted at 1:800 and staining in paraffin-embedded human breast cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.
