Arsenic trioxide (ATO), a component of the traditional Chinese medicine arsenic sublimate, promotes apoptosis and induces leukemic cell differentiation. Combined with all-trans-retinotic acid (ATRA), ATO has become the first-line induction therapy in treating acute promyelocytic leukemia (APL). The most common side effects of ATO include hepatotoxicity, gastrointestinal symptoms, water-sodium retention, and nervous system damage. In this report, we present a rare side effect, rhabdomyolysis, in a 68-year-old female APL patient who was treated with ATO. After taking 10 mg ATO daily for 6 days, she presented shortness of breath, myodynia, elevated creatine kinase, and acute renal insufficiency. This report describes the first case of ATO-induced rhabdomyolysis.

S100A9, a calcium-binding protein, participates in the inflammatory process and development of various tumors, thus attracting much attention in the field of cancer biology. This study aimed to investigate the regulatory mechanism of and its function involvement in APL. We used real-time quantitative PCR to determine whether PML/RARα affects the expression of in NB4 and PR9 cells upon ATRA treatment. ChIP-based PCR and dual-luciferase reporter assay system were used to detect how PML/RARα and PU.1 regulate promoter activity. CCK-8 assay and flow cytometry were employed to observe the viability and apoptosis of NB4 cells when was overexpressed. Results showed that was an ATRA-responsive gene, and PML/RARα was necessary for the ATRA-induced expression of in APL cells. In addition, PU.1 could bind to the promoter of , especially when treated with ATRA in NB4 cells, and promote its activity. More importantly, overexpression of induced the apoptosis of NB4 cells and inhibited cell growth. Collectively, our data indicated that PML/RARα and PU.1 were necessary for the ATRA-induced expression of in APL cells. Furthermore, promoted apoptosis in APL cells and affected cell growth.
