Rationale: Cytokine storm is now considered to be a systemic inflammatory response, but local cytokine storm may exist in systemic diseases of the blood system. Monitoring of regional cytokine storm is an important clue for the diagnosis of systemic diseases. Patient concerns: A 72-years-old male presented to our hospital with multiple serosal effusion without solid mass or enlarged lymph nodes. We found that the level of cytokines in ascites was tens to hundreds of times higher than that in plasma, mainly IL-6 and IL-8. Diagnoses: The patient was diagnosed with multiple serous effusion, hemophagocytic syndrome, B-cell lymphoma, Epstein–Barr virus infection, and hypoproteinemia. Interventions: During hospitalization, the patient was treated with 5 courses of R-CVEP therapy and supportive treatment. Outcomes: After the first R-CVEP regimen, the patient’s condition was evaluated as follows: hemophagocytic syndrome improved: no fever; Serum triglyceride 2.36 mmol/L; Ferritin 70.70 ng/L; no hemophagocyte was found in the bone marrow; the lymphoma was relieved, ascites disappeared, and bone marrow cytology showed: the bone marrow hyperplasia was reduced, and small platelet clusters were easily seen. Bone marrow flow cytometry showed that lymphocytes accounted for 13.7%, T cells increased for 85.7%, CD4/CD8 = 0.63, B cells decreased significantly for 0.27%, and NK cells accounted for 10.2%. Blood routine returned to normal: WBC 5.27 × 109/L, HB 128 g/L, PLT 129 × 109/L; Epstein–Barr virus DNA < 5.2E + 02 copies/mL; correction of hypoproteinemia: albumin 39.7 g/L. Lessons: Cytokines in ascites are significantly higher than those in plasma by tens to hundreds of times, suggesting that “regional cytokine storms” may cause serosal effusion.
The purpose of the present study was to evaluate cimigenol (Cim) treatment effects to cell proliferation by breaking bone marrow stromal cells (BMSCs) through C-X-C chemokine receptor type 4 (CXCR4)/stromal cell-derived factor-1α (SDF-1α) pathway. MV-4-11 and U937 cell lines were used. The present study was divided into two parts. First, the cell lines were divided into normal control (NC), BMSC (cells co-cultured with BMSCs), BMSC + DMSO, BMSC + Low (treated with 5 mg/ml Cim), BMSC + Middle (treated with 10 mg/ml Cim), BMSC + High (treated with 20 mg/ml Cim). In the second step, the cell lines were divided into NC, BMSC, BMSC + BL8040 (treated with BL8040 which inhibits CXCR4), BMSC + Cim and BMSC + Cim + BL8040. EdU positive cell numbers were measured by EdU assay and apoptosis rate by flow cytometry and TUNEL assay. Relative gene and protein expression was measured by reverse transcription-quantitative PCR and western blotting assay. BMSCs were able to protect proliferation of cancer cells and decreased cell apoptosis compared with the NC group (P<0.001, respectively). With Cim supplement, the cell proliferation was decreased with cell apoptosis increasing compared with NC group (P<0.001 respectively). However, the anti-tumor effects of Cim were not significantly different from the BL8040 treated groups (P<0.001, respectively). In conclusion Cim decreased acute myeloid leukemia cells protected by BMSCs through the CXCR4/SDF-1α pathway.
PURPOSE:Cimicifuga dahurica (C. dahurica), which has been used in traditional oriental medicine for a long period, was reported to exert extensive antitumor activity, but the effect and molecular biological mechanism of C. dahurica on multiple myeloma (MM) has not been elaborated. Tumor-associated macrophages (TAMs) exhibit a sustained polarization between tumor killing M1 subtype and tumor supporting M2 subtype. And a lower ratio of M1/M2 is associated with tumor angiogenesis, proliferation and invasion. We explored the inhibitory effect of the aqueous extract of the root of C. dahurica (CRAE) on tumor growth by reprogramming macrophage polarization in the tumor microenvironment.METHODS:Mice bearing SP2/0 multiple myeloma were treated with CRAE. Western blotting (WB), immunohistochemistry (IHC) and immunofluorescence staining were utilized to assess tumor growth and TAM populations. Macrophages were depleted by injection of clodronate liposomes to determine and measure the role of CRAE as an anti-tumor agent by targeting macrophages. To simulate tumor microenvironment, MM cells H929 and TAMs were co-cultured using the transwell co-culture system. By using CRAE as an immunoregulator in M2-like macrophages, we analyzed CRAE-treated macrophage-associated surface markers and cytokines by flow cytometry and WB.RESULTS:The results indicated that CRAE treatment could reduce tumor burden of MM mice and a high degree of M1-like macrophages infiltration was detected in tumor tissues. In vitro co-culture system, CRAE significantly promoted the polarization of M2 to M1 phenotype, which led to the increase in apoptosis of myeloma cells. It was found that the M1 polarization induced by CRAE depended on the TLR4-MyD88-TAK1-NF-κB signal transduction.CONCLUSION:This study elucidated the anticancer mechanism of the aqueous extract of C. dahurica (CRAE) through reprogramming macrophage polarization and highlighted that CRAE could act as a potential novel option for cancer immunotherapy.

Solasonine, the main active ingredient of Solanum nigrum L ., has been reported to exert extensive antitumor activity. However, the antitumor effects in acute monocytic leukemia and the exact mechanisms involved are unknown. In this study, we investigated the role of solasonine on inhibiting the progression of acute monocytic leukemia. Our findings showed that solasonine inhibited the proliferation of acute monocytic leukemic cell lines (THP-1 and MV4-11) in vitro . Solasonine promoted apoptosis and induced cell cycle arrest in the G2/M phase. Analysis of RNA-seq data suggested that solasonine correlated with increased expression of genes in the AMPK/FOXO3A pathway. Inhibition of AMPK with compound C followed by treatment with solasonine showed that solasonine reduced apoptosis, caused less cell cycle arrest, and inactivated the AMPK/FOXO3A axis in THP-1 and MV4-11 cells. Solasonine also inhibited tumor growth by the activation of the AMPK/FOXO3A axis. In conclusion, solasonine inhibited the progress of acute monocytic leukemia in vitro and in vivo and triggered the apoptosis and cell cycle arrest in the G2/M phase by upregulating the AMPK/FOXO3A pathway.
Shengma Biejia decoction (SMBJD), a traditional Chinese formula recorded in the Golden Chamber , has been widely used for the treatment of malignant tumors. However, its underlying molecular targets and mechanisms are still unclear. This study showed that SMBJD inhibited tumor growth and stimulated hemogram recovery significantly in a multiple myeloma xenograft model. Western blot and immunohistochemistry assays of tumor tissues showed that SMBJD reduced the ratio of autophagy-related proteins LC3-II/LC3-I, while P62 and apoptosis-related proteins cleaved caspase-3/caspase-3 and Bax/Bcl-2 were upregulated. In vitro experiments demonstrated the time-dependent and dose-dependent cytotoxicity of SMBJD on multiple myeloma cell lines H929 and U266 through MTT assays. The LC3-II/LC3-I ratio and number of GFP-LC3 puncta showed that SMBJD inhibited the autophagy process of H929 and U266 cells. Moreover, both SMBJD and 3-methyladenine (3-MA) caused a decrease in LC3-II/LC3-I, and SMBJD could not reverse the upregulation of LC3-II/LC3-I caused by bafilomycin A1 (Baf-A1). Furthermore, the results of annexin V-FITC and propidium iodide double staining demonstrated that SMBJD treatment induced the apoptosis of H929 and U266 cells. These data prove that SMBJD inhibits autophagy and promotes apoptosis in H929 and U266 cells. The results also show that rapamycin could reduce the rate of SMBJD-induced apoptosis in H929 and U266 cells, at a concentration which had no effect on apoptosis but activated autophagy. In addition, analysis of the mechanism indicated that levels of phosphorylated ERK and phosphorylated mTOR were increased by treatment with SMBJD in vivo and in vitro . These results indicate that SMBJD, an old and effective herbal compound, could inhibit the viability of H929 and U266 cells and induce autophagy-mediated apoptosis through the ERK/mTOR pathway. Thus, it represents a potential therapy strategy for multiple myeloma.
Background Tumor associated macrophages (TAMs), a kind of inflammatory cells in the tumor microenvironment, are crucial for the occurrence and development of various tumors which increased the expression of CD163. Nevertheless, not much has been established regarding soluble CD163 and its connection to tumor diagnosis. In this case, a meta-analysis was conducted to determine the tumor diagnostic importance of serum sCD163. Methods In order to assess the correlation between sCD163 and the overall survival (OS) or progression-free survival (PFS) among tumor patients, a systematic perusal of literature published until June 2020 was conducted. Relevant data were primarily obtained from papers that have the following qualifications: 1) a confidence interval (CI) of 95%; 2) a report of the hazard ratios; and, 3) pooled by means of the Mantel-Haenszel random-effect representation. Results For the final meta-analysis, eight papers comprised of 1,236 cases were involved. Through pooled investigation, it was determined that a correlation exists between elevated serum sCD163 and worse OS (HR = 2.24, 95% CI: 1.50-3.35, P < 0.001) and PFS (HR = 3.90, 95% CI: 2.33-6.52, P < 0.001) among tumor cases. Subgroup analysis stratified by medium age at diagnosis demonstrated that patients over 60 years old with high sCD163 had worse OS (HR 2.28, 95% CI: 1.58-3.29, P < 0.001) than under 60 (HR 1.43, 95% CI: 1.15-1.77, P = 0.001). Subgroup analysis revealed that analysis method and medium age at diagnosis were the potential source of heterogeneity. Conclusions Overall, diagnosis of tumor cases can be adversely determined through substantial sCD163 levels. Consequently, it is encouraged that extensive researches regarding the rates of cancer survival be accomplished.

Context ShengMaBieJia decoction (SMBJD) is used to treat solid and hematological tumours; however, its anti-angiogenesis activity remains unclear. Objective This study verified the anti-angiogenic effects of SMBJD in vitro and in tumour-bearing acute myeloid leukaemia (AML) mouse models. Materials and methods In vivo, the chicken chorioallantoic membrane (CAM) and BALB/c null mouse xenograft models were treated with SMBJD (0, 2, 4, and 8 mg/mL) for 48 h and for 2 weeks, respectively. Anti-angiogenic activity was assessed according to microvessel density (MVD) and immunohistochemistry (IHC) targeting CD31 and VEGFR2. In vitro, proliferation viability, migratory activity and tube formation were measured. Western blots and polymerase chain reaction (PCR) assays were used to examine the levels of PI3K, Akt, and VEGF. Results HPLC analyses revealed the active constituents of SMBJD such as liquiritin, cimifugin, ferulic, isoferulic, and glycyrrhizic acids. In vitro, SMBJD treatment decreased cellular migration, chemotaxis, and tube formation at non-cytotoxic concentrations (2, 4, and 8 mg/mL) in a time- and dose-dependent manner. The dosage of less than IC20 is considered safe. In vivo, CAM models exhibited a decrease in MVD, and the tissues of xenografted mice possessed reduced CD31 and VEGFR2 expression. Conditioned media (CM) from AML cells (HL60 and NB4 cells) treated with non-cytotoxic doses of SMBJD inhibited chemotactic migration and tube formation in vitro. Both CM (HL60) and CM (NB4) exhibited downregulated expression of PI3K, Akt, and VEGF. Discussion and conclusions SMBJD inhibited angiogenesis in AML through the PI3K/AKT pathway, which might be combined with targeted therapy to provide more effective treatment.

The objective was to investigate the effects of tenacigenin B on apoptosis of human acute myeloid leukemia cell lines HL-60, NB-4, and K562 and the underlying mechanisms. The inhibitory effect of tenacigenin B on the proliferation of human acute myeloid leukemia cell lines HL-60, NB-4 and K562 was observed by MTT assay; the effect of tenacigenin B on the morphology of apoptotic nuclei in these cell lines was detected using Hoechst 33258 staining; the effect of tenacigenin B on the apoptosis rate and mitochondrial membrane potential of these cell lines was determined by flow cytometry; expression of apoptosis-related proteins, including caspase-3, caspase-8, caspase-9, and PARP, and p38, p-p38, ERK1/2, pERK1/2, JNK1/2, and p-JNK1/2 in HL-60 cells was determined by Western blot after treated with enacigenin B for 24 h; and a nude mouse xenograft model was constructed by subcutaneous injection of HL-60 cells to evaluate the antitumor effect of tenacigenin B in vivo. Tenacigenin B inhibited the proliferation of human acute myeloid leukemia cell lines and induced cell apoptosis in a concentration- and time-dependent manner, and caspase-3, caspase-8, and caspase-9 were activated with cleaved PARP. In addition, the phosphorylation of p38, JNK1/2 and ERK1/2 proteins was also up-regulated to different degrees. Further inhibition assay confirmed that the activation of caspase induced by tenacigenin B was reversed by inhibiting the MAPK pathway. In vivo assay showed that tenacigenin B effectively inhibited the growth of transplanted tumors. In conclusion, tenacigenin B induces apoptosis of acute myeloid leukemia cells via caspase-dependent pathways, and upstream MAPK signaling pathway is involved in the regulation of this biological process.
Background: The aim of this study was to examine the effects and mechanisms of tenacigenin B in lymphoma treatment by in vitro and in vivo experiment. Material/Methods: Raji cells were treated by difference methods. Measuring the cell proliferation of difference groups was done by MTT assay; cell apoptosis and cell cycle of difference groups were evaluated by flow cytometer; relative mRNA expression was evaluated by real-time polymerase chain reaction (RT-PCR), and relative protein expressions were measured by western blot assay in an in vitro study. In an in vivo study, we used a nude mice model to explore the anti-tumor effects and mechanism of tenacigenin B. Cell apoptosis was measured by TUNEL assay; relative protein expressions were evaluated by immunohistochemistry assay, and relative mRNA expression was evaluated by RT-PCR. In addition, the blood components of difference groups were measured. Results: Compared with the Normal control group, the cell proliferation rate was significantly downregulated, with cell apoptosis significantly increasing with G1 phase in the Drug group and the si-Aurora-A group (P<0.05, respectively). The PTEN, PI3K, AKT, P53, and P21 mRNA and protein expressions of the Drug group, the si-Aurora-A group, and the si-Aurora-A+Drug group were significantly different (P<0.01, respectively), The tumor volume and weight of the Drug group, the si-Aurora-A group, and the si-Aurora-A+Drug group were significantly suppressed compared with the Normal group (P<0.01, respectively). The positive apoptosis cell number in the Drug group, the si-Aurora-A group, and si-Aurora-A+Drug group were increased compared with that of Normal group (P<0.01, respectively). Conclusions: Tenacigenin B had anti-tumor effects on lymphoma via regulation of Aurora-A in vitro and in vivo.
