An overview of pim kinase as a target in multiple myeloma.

Multiple myeloma (MM) is the second common hematologic malignancy manifesting as a clonal proliferation of plasma cells in the bone marrow. In recent years, high expression and activity of pim kinase have been found to be associated with both the progression and prognosis of a significant proportion of malignant diseases. Therefore, pim kinase has become a potential therapeutic target in the treatment of MM and some pim kinase inhibitors have demonstrated good efficacy in clinical trials. Based on nearly the entire literature searched from PubMed in the field of pim kinase in MM, the paper concluded how pim kinase got involved in the proliferation of myeloma cells, the progression of bone disease infiltration, and even in the regulation of the immune microenvironment. Next as a very promising drug, the effectiveness of pim kinase inhibitors as single agents or in combination with other drugs in the treatment of MM was also summarized. Our analysis will guide the clinical use of pim kinase inhibitors for managing tumor load and bone disease in MM patients.
