HaCaT cells were fixed with 4% paraformaldehyde (PFA) for 10 minutes, permeabilized with 0.5% Triton X-100 for 3 minutes, and blocked with 5% FBS for 60 minutes. Then the cells were intracellularly stained overnight at 4°C with (A) 1:250 diluted (2 µg/ml) Alexa Fluor® 647 rat IgG2a (Cat. No. 400526) or with Alexa Fluor® 647 anti-human Cytokeratin 7 antibody (red) at (B) 1:250 (2 µg/ml) and (C) 1:1000 (0.5 µg/ml) dilution. Nuclei were counterstained with DAPI (blue). The image was captured with a 60X objective.

Description

Keratin 7 (KRT7) belongs to type II keratin and is expressed in the epithelia lining the cavities of internal organs, gland ducts and blood vessels. The function of KRT7 is still not clear but it has been suggested involved in the translational regulation of the human papillomavirus type 16 E7 mRNA (HPV16 E7). In cancer, the expression of KRT7 is observed in many types of carcinoma and is associated with neoplasm progression. The diverse and unique expression pattern of KRT7 is often used as a diagnosis indicator in epithelial origin carcinoma. For example, aberrant KRT7 expression is observed in triple negative breast cancer. In bladder cancer, loss of KRT7 results in promoting proliferation of the bladder urothelium.
