Target/Biomarker information

CYFRA21-1, also known as Cytokeratin 19 Fragment 21-1, is a noteworthy biomarker within the context of cats (felines). It originates from cytokeratin 19, a structural protein that plays a pivotal role in maintaining the cytoskeletal integrity of epithelial cells. Epithelial cells are a fundamental component of various feline tissues and organs, including the respiratory system. When these cells experience pathological changes, such as injury or malignant transformation, CYFRA21-1 fragments can be released into the bloodstream, making it a valuable indicator of epithelial cell health. At the molecular level, CYFRA21-1 is composed of specific fragments of cytokeratin 19, notably the 21-1 fragment. These soluble protein fragments can be detected through blood tests. In healthy cats, CYFRA21-1 levels are typically low. However, when there is damage or malignancy in epithelial tissues, such as the lungs, the levels of CYFRA21-1 can significantly increase. This makes CYFRA21-1 a crucial biomarker for assessing the health of the respiratory and epithelial systems in felines.
