Abstract
Cisplatin is a platinum-based drug that is widely used to treat various types of cancer. However, cisplatin is known to cause severe adverse effects, such as nephrotoxicity and ototoxicity. Clock genes, such as Bmal1 and Clock, regulate cisplatin-related homeostasis genes, such as Oct2 and Mate1. Although these clock genes may be involved in cisplatin-induced nephrotoxicity, their associations with other clock genes remain unclear. The aim of the present study was to investigate whether seven clock genes (Ciart, cryptochrome 1 (Cry1), Cry2, Npas2, Per1, Per2, and Per3) regulate cisplatin-induced renal toxicity in a renal cortex tubule cell line (MuRTE61). Cisplatin treatment decreases MuRTE61 cell viability in a dose-dependent manner. Cry2 expression levels increased after treatment with cisplatin for 24 h. Notably, Cry2 overexpression alleviated cisplatin-induced suppression of cell proliferation, apoptosis, and platinum content in MuRTE61 cells. Moreover, Cry2 overexpression upregulated the efflux-related transporters (Atp7a and Mrp2). These results suggest that Cry2 protects against cisplatin toxicity by reducing Pt accumulation and increasing the expression of Atp7a and Mrp2.
期刊介绍:
Biological and Pharmaceutical Bulletin (Biol. Pharm. Bull.) began publication in 1978 as the Journal of Pharmacobio-Dynamics. It covers various biological topics in the pharmaceutical and health sciences. A fourth Society journal, the Journal of Health Science, was merged with Biol. Pharm. Bull. in 2012.
The main aim of the Society’s journals is to advance the pharmaceutical sciences with research reports, information exchange, and high-quality discussion. The average review time for articles submitted to the journals is around one month for first decision. The complete texts of all of the Society’s journals can be freely accessed through J-STAGE. The Society’s editorial committee hopes that the content of its journals will be useful to your research, and also invites you to submit your own work to the journals.
