Abstract: Pyrroline-5-Carboxylate Reductase-1(PYCR1)is a key enzyme for synthesis of mitochondrial proline.More and more studies have shown that PYCR1 is highly expressed in various malignant tumors,affecting the biological behaviors such as tumor cell proliferation,apoptosis,invasion and migration,and is closely related to clinical prognosis.It is expected to become a new tumor biomarker,but its mechanism of action is relatively complex.This article will review the role of PYCR1 in tumorigenesis and development from three aspects: its mechanism of action,clinical significance and the effect of PYCR1 inhibitors on tumors.

Key words: PYCR1, Proline, Tumor, Mechanism of action
