Abstract:
Objective:To study the expressions of C-C class chemokine 17 (CCL17), C-C class chemokine 22 (CCL22), and C-C chemokine receptor 4 (CCR4) in newly diagnosed multiple myeloma (NDMM) for analyzing their correlations with clinical features and to preliminarily explore their roles in the development of NDMM.Methods:The study included 40 patients with NDMM and 20 healthy volunteers from the Department of Hematology of the Affiliated Hospital of Zunyi Medical University from July 2020 to December 2022. Peripheral blood, bone marrow, and bone marrow biopsy tissue samples were collected from the two groups. The expression levels of CCL17, CCL22, and CCR4 in patients with NDMM were analyzed using real-time quantitative reverse transcriptase polymerase chain reaction (RQ-PCR), enzyme-linked immunosorbent assay (ELISA), and immunohistochemistry. The mRNA expression levels of CCL17, CCL22, and CCR4 in the bone marrow mononuclear cell (BMMNC) of patients with NDMM were analyzed to assess their correlations with clinical indicators.Results:The mRNA expression levels of CCL17, CCL22, and CCR4 in BMMNC were higher in patients with NDMM than in controls (all P<0.05). The protein expression levels of CCL17 and CCL22 in peripheral blood supernatants and bone marrow supernatants were higher in patients with NDMM than in controls (all P<0.05). The expression levels of CCL17, CCL22, and CCR4 in bone marrow biopsy tissues were higher in patients with NDMM than in controls (all P<0.05). The mRNA expression level of CCL17 was increased in NDMM patients with combined anemia, bone damage, renal damage, and M protein level ≥30 g/L (all P<0.05). The mRNA expression level of CCL22 was increased in NDMM patients with combined anemia, bone damage, and renal damage (all P<0.05). The mRNA expression level of CCR4 was increased in NDMM patients with combined anemia and renal damage (all P<0.05) . Conclusion:CCL17, CCL22, and CCR4 were highly expressed in clinical samples from patients with NDMM compared to those from controls, and they may be involved in the occurrence and development of NDMM.
