Sirtuin 2 knockdown inhibits cell proliferation and RAS/ERK signaling, and promotes cell apoptosis and cell cycle arrest in multiple myeloma.

ABSTRACT: The present study aimed to explore the regulatory role of sirtuin 2 (SIRT2) in malignant progression of multiple myeloma (MM) and the potential associated signaling pathways. In total, 30 patients with MM and 15 healthy bone marrow donors were enrolled in the current study and their bone marrow samples were collected to isolate the plasma cells. The expression levels of SIRT2 were detected in MM cell lines (KMS‑28BM, U266, RPMI‑8226 and NCI‑H929) and normal plasma cells (collected from healthy bone marrow donors as the control) via reverse transcription‑quantitative PCR (RT‑qPCR) and western blot analysis. SIRT2 knockdown was established by transfecting two MM cell lines (RPMI‑8226 and NCI‑H929 cells) with short hairpin RNA‑SIRT2 recombinant plasmid; the control group was transfected with
