Iron oxide nanoparticles inhibit tumor growth by ferroptosis in diffuse large B-cell lymphoma.

Since the approval by the Food and Drug Administration (FDA), ferumoxytol and other iron oxide nanoparticles (IONs) have been widely used as iron supplements for patients with iron deficiency. Meanwhile, IONs have also been used as contrast agents in magnetic resonance imaging and as drug carriers. Importantly, IONs have demonstrated a significant inhibitory effect on the growth of tumors, including hematopoietic and lymphoid tumors, such as leukemia.

[Correlation between Peripheral Blood Intermediate Monocytes Increased and the Disease Progression of Patients with Diffuse Large BCell Lymphoma].

Unlabelled: AbstractObjective: To explore the distribution characteristics and clinical significance of peripheral blood monocyte subgroups in patients with diffuse large Bcell lymphoma(DLBCL).

Methods: The percentage of peripheral blood monocyte subsets of 82 DLBCL patients (including 32 newly diagnosis, 29 remission and 21 relapse) and 30 healthy controls were detected by flow cytometry, and the correlation with the clinical characteristics and its diagnostic value of DLBCL were analyzed.

Results: The proportion of intermediate monocytes in patients with newly diagnosed DLBCL group was higher than that in healthy controls (t=5.

CC chemokine receptor 2 (CCR2) expression promotes diffuse large B-Cell lymphoma survival and invasion.

In recent years, CC chemokine receptor 2 (CCR2) has been found to be involved in tumor growth, angiogenesis, epithelial mesenchymal transition, metastasis, and immune escape. CCR2 overexpression was first identified as a poor prognostic predictor in diffuse large B-cell lymphoma (DLBCL) in our published article, but the mechanisms involved remain unknown. In this work, we collected data from another 138 patients with DLBCL data and verified the CCR2 expression level and its relationship to clinicopathological characteristics.
