About Cizzle Biotechnology

Cizzle Biotechnology is a spin- out from the University of York that  is  developing a blood test for the early detection of lung cancer. Its proof-of-concept prototype test is based on the work of Professor Coverley and colleagues to detect a stable plasma biomarker, a variant of CIZ1 known as CIZ1B. CIZ1 is a naturally occurring cell nuclear protein involved in DNA replication, and the targeted CIZ1B variant is highly correlated with early-stage lung cancer.
