AI Article Synopsis
- The study aimed to assess the effects of Lycium barbarum polysaccharide (LBP) on mice suffering from myelosuppression caused by mitomycin C (MMC).
- Mice were treated with MMC to induce myelosuppression and then given varying doses of LBP to see if it could help recover blood cell counts.
- Results indicated that LBP, particularly at higher doses, significantly improved red blood cells and platelet counts in the affected mice, though it did not substantially affect neutrophil levels.
Article Abstract
Aim: To investigate the therapeutic effects of Lycium barbarum polysaccharide (LBP) on mitomycin C (MMC)-induced myelosuppressive mice.
Methods: Mice were intravenously injected with MMC 150 mg/kg for two consecutive days from day -1 to day 0 to produce severe myelosuppression, and then treated by s.c. injections of LBP (100 or 200 mg/kg/day) from days 0 to 6. Blood samples were collected from the tail veins of mice on days 7, 10, 12, 14, 17, 19, 21, 24 and 27, and peripheral white blood cells (WBC), red blood cells (RBC), hemoglobin (HGB) and platelet counts (PLT) etc. were monitored.
Results: LBP at 100 mg/kg (LBP-L) on day 14 and LBP at 200 mg/kg (LBP-H) on days 10, 14, 17, 19 and 21, significantly ameliorated the decrease of peripheral RBC, HGB and hematocrit (HCT) of myelosuppressive mice compared to the control. LBP-L on days 12 and days 14 and LBP-H on days 10, 12, 14, 17, 19 and 21, significantly enhanced peripheral PLT recovery of myelosuppressive mice compared to the control. LBP-H on days 12, 17, 19 and 21, significantly inhibited the increase of mean platelet volume (MPV) of myelosuppressive mice compared to the control. LBP showed no obviously effect on neutropenia induced in mice by MMC.
Conclusion: LBP is effective on peripheral RBC and PLT recovery of MMC-induced myelosuppressive mice.

Patients with benzene-induced leukemia undergo a continuous transformation from myelosuppression to malignant proliferation. However, the underlying mechanisms in this process remain unknown. Our previous studies have shown that the pathways involved in self-renewal capacity of bone marrow (BM) cells in Mll-Af9 mice exposed to benzene for life are significantly activated after severe blood toxicity.

Objective: This study aims to investigate the effect of Gallic Acid (GA) on the alleviation of chemotherapy-induced bone marrow suppression, with a comparison to Diyu sheng bai tablets (DYSB) and RhG-CSF.
Methods: A mouse model of bone marrow suppression was established in BALB/c mice using intraperitoneal injections of cyclophosphamide (CTX). All procedures were performed after obtaining ethical clearance from the institutional animal ethics committee.

Article Synopsis
- Chemotherapy-induced myelosuppression (CIM) hinders blood cell production, making it a significant issue in cancer treatment.
- Trilaciclib (TC) is the only FDA-approved CDK4/6 inhibitor that protects bone marrow by stopping the growth of certain cells, and its derivatives show strong potential as effective treatments for CIM.
- Among these, one derivative displayed excellent inhibitory activity, low toxicity, great selectivity, and effective penetration into bone marrow, indicating it could improve treatment outcomes for individuals experiencing myelosuppression from chemotherapy.

Myelosuppression is a serious and common complication of targeted therapy for cancer patients, and there are few studies exploring the efficacy of natural drugs in this condition. Niraparib is a widely used targeted therapy for the treatment of advanced ovarian cancer. As a poly (ADP-ribose) polymerase (PARP) inhibitor, niraparib significantly improves progression-free and overall survival in patients.

Trained immunity represents a functional state of the innate immune response, characterized by enduring epigenetic reprogramming of innate immune cells. This phenomenon facilitates a sustained and advantageous reaction of myeloid cells to subsequent challenges. Bletilla striata polysaccharide (BSP) is the primary active component of Bletilla striata, mainly consisting of mannose and glucose in its chemical structure.
