Conditional expression of MCM7 increases tumor growth without altering DNA replication activity
Copyright policy )Conditional expression of MCM7 increases tumor growth without altering DNA replication activity
The minichromosome maintenance (MCM) 2–7 complex is a putative DNA helicase complex that facilitates the initiation of DNA replication. Here, we generated a cell line MCM7+/−/MCM7‐FLAG, in which one allele of MCM7 is mutated whereas a tetracycline‐repressible promoter could manipulate the expression of exogenous MCM7 protein. Overexpressed MCM7 protein supports efficient DNA replication of Epstein–Barr virus oriP and rapid formation of tumors in nude mice without altering the activity of cellular DNA replication. This system provides a unique setting for studying the function of MCM7 and for screening for potential therapeutics for malignant tumors.
