Abstract
In eukaryotic cells, primases are the key polymerase during DNA replication and DNA damage repair, which includes primase subunit 1 (PRIM1) and primase subunit 2 (PRIM2). Recent studies reported that the aberrant expression and activity of PRIM enzymes are closely associated with the carcinogenesis and development of various cancers. PRIM1 is overexpressed in hepatocellular carcinoma, breast cancer, and other cancers, while PRIM2 is highly expressed in lung cancer, gastrointestinal cancer, and other cancers. Further studies revealed that the knockdown of PRIM1 promoted the apoptosis of liver cancer cells, while Dihydroartemisinin (DHA) can inhibit PRIM2 expression, suppress lung cancer cell proliferation, and result in ferroptosis. The present review summarized the recent advancements in the research of the aberrant expression of PRIM1 and PRIM2 and their activity in DNA replication, DNA damage repair, and carcinogenesis. Furthermore, the strategies targeting PRIM1 or/and PRIM2 become potential therapeutic approaches in cancer treatment.
期刊介绍:
Current Cancer Drug Targets aims to cover all the latest and outstanding developments on the medicinal chemistry, pharmacology, molecular biology, genomics and biochemistry of contemporary molecular drug targets involved in cancer, e.g. disease specific proteins, receptors, enzymes and genes.
Current Cancer Drug Targets publishes original research articles, letters, reviews / mini-reviews, drug clinical trial studies and guest edited thematic issues written by leaders in the field covering a range of current topics on drug targets involved in cancer.
As the discovery, identification, characterization and validation of novel human drug targets for anti-cancer drug discovery continues to grow; this journal has become essential reading for all pharmaceutical scientists involved in drug discovery and development.
