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.

Abstract Background: Multiple myeloma (MM) is a hematological malignancy with clonal plasma cell hyperplasia, which is still an incrurable disease since chemoresistance remains the major problem in MM management. Quercetin, a kind of dietary flavonoids, has shown its anticancer activity in many kinds of cancer cell lines and we tried to explore the effect of quercetin in MM. Methods: In vitro, we examined the proliferation of MM cell lines(RPMI8226,ARP-1,MM1R) after treatment with quercetin combined with or without dexamethasone by MTT.Flow cytometry was used to detect apoptosis and cell cycle of MM cells induced by quercetin with or without dexamethasone.Then we detected mRNA and protein expression associated with apoptosis and cell cycle arrest by semiquantitative real time-polymerase chain (qRT-PCR)and western blot analysis. In vivo,a xenograft mice model of human myeloma was established and the mice received vehicle or quercetin alone or dexamethasone alone or quercetin combinded with dexamethasone, and the tumorburdern and the tumor tissue samples were analyzed by tumor volume and immunohistochemistry. Results: Quercetin inhibited proliferation of MM cells by inducing apoptosis and cell cycle arrest in the G0/G1 or G2 phase(quercetin group vs control,p<0.05).Western blot showed that quercetin activated caspase3,caspase9,PARP-1 and increased cytochrome C release. C-myc and cyclinD1 expression were down-regulated and p21 were upregulated. Quercetinalso displays synergistic inhibition effect with dexamethasone in vitro (quercetin with dexamethasone vs quercetin only or dexamethasone only,p<0.05) and western bolt confirmed these results.In vivo,tumor burdern of xenograft mice modeltreated by quercetin was significantly lower than those of control(quercetin group vs control,p<0.05). Conclusions: Quercetin inhibits proliferation of MM cells by inducing apoptosis and cell cycle arrest in the G0/G1 or G2 phase through downregulating c-myc and cyclinD1 and upregulating p21 .Quercetinalso displays synergistic inhibition effect with dexamethasone.Thus,quercetin combination with dexamethasone therapy may be an effective option for MM patients.

Crocin is a carotenoid of the saffron extract that exhibits antitumor activity against many human tumors. However, the effects of crocin on HL-60 cells in vivo have not been evaluated. This study aimed to examine the effects of crocin on HL-60 cells in vitro and in vivo and investigate the underlying mechanisms. HL-60 cells were treated by crocin, and cell proliferation, apoptosis, and cell cycle profiles were examined by MTT assay, AO/EB staining, and flow cytometry, respectively. Furthermore, HL-60 cells were xenografted into nude mice and treated by crocin, the tumor weight and size were calculated, and the expression of Bcl-2 and Bax in xenografts was detected by immunohistochemical staining. The results showed that crocin (0.625–5 mg/mL) inhibited HL-60 cell proliferation and induced apoptosis and cell cycle arrest at G0/G1 phase, in a concentration and time-dependent manner. In addition, crocin (6.25, 25 mg/kg) inhibited the tumor weight and size of HL-60 xenografts in nude mice, inhibited Bcl-2 expression, and increased Bax expression in xenografts. In summary, crocin inhibits the proliferation and tumorigenicity of HL-60 cells, which may be mediated by the induction of apoptosis and cell cycle arrest and the regulation of Bcl-2 and Bax expression.

Abstract BackgroundPhosphoglucomutase 1(PGM1) is known for its involvement in cancer pathogenesis. However, its biological role in colorectal cancer (CRC) is unknown. Here, we studied the functions and mechanisms of PGM1 in CRC.Methods We verified PGM-1 as a DEG by a comprehensive strategy of the TCGA-COAD dataset mining and computational biology. Relative levels of PGM-1 in CRC tumors and adjoining peritumoral tissue were identified by qRT-PCR, WB, and IHC staining in a tissue microarray. PGM1 functions were analyzed using CCK8, EdU, colony formation, cell cycle, apoptosis, and Transwell migration and invasion assays. The influence of PGM1 was further investigated using tumor formation in vivo.ResultsPGM1 mRNA and protein were both reduced in CRC and the reduction was related to CRC pathology and overall survival. PGM1 knockdown stimulated both proliferation and colony formation, promoting cell cycle arrest and apoptosis while overexpression has opposite effects in CRC cells both in vivo and in vitro. Furthermore, we lined the actions of PGM1 to the PI3K/ AKT pathway. ConclusionWe verified that PGM1 suppresses CRC through the PI3K/ AKT pathway. These results suggest the potential for targeting PGM1 in CRC therapies.
