Kim IH, Eom T, Park JY, Kim HJ, Nam TJ. Dichloromethane fractions of Calystegia soldanella induce S‑phase arrest and apoptosis in HT‑29 human colorectal cancer cells. Mol Med Rep 2021; 25:60.

Abstract
Calystegia soldanella is a halophyte and a perennial herb that grows on coastal sand dunes worldwide. Extracts from this plant have been previously revealed to have a variety of bioactive properties in humans. However, their effects on colorectal cancer cells remain poorly understood. In the present study, the potential biological activity of C. soldanella extracts in the colorectal cancer cell line HT-29 was examined. First, five solvent fractions [n-hexane, dichloromethane (DCM), ethyl acetate, n-butanol and water] were obtained from the crude extracts of C. soldanella through an organic solvent extraction method. In particular, the DCM fraction was demonstrated to exert marked dose- and time-dependent inhibitory effects according to results from the cell viability assay. Data obtained from the apoptosis assay suggested that the inhibition of HT-29 cell viability induced by DCM treatment was attributed to increased apoptosis. The apoptotic rate was markedly increased in a dose-dependent manner, which was associated with the protein expression levels of apoptosis-related proteins, including increased Fas, Bad and Bax, and decreased pro-caspase-8, Bcl-2, Bcl-xL, pro-caspase-9, pro-caspase-7 and pro-caspase-3. A mitochondrial membrane potential assay demonstrated that more cells became depolarized and the extent of cytochrome c release was markedly increased in a dose-dependent manner in HT-29 cells treated with DCM. In addition, cell cycle analysis confirmed S-phase arrest following DCM fraction treatment, which was associated with decreased protein expression levels of cell cycle-related proteins, such as cyclin A, CDK2, cell division cycle 25 A and cyclin dependent kinase inhibitor 1. Based on these results, the present study suggested that the DCM fraction of the C. soldanella extract can inhibit HT-29 cell viability whilst inducing apoptosis through mitochondrial membrane potential regulation and S-phase arrest. These results also suggested that the DCM fraction has potential anticancer activity in HT-29 colorectal cells. Further research on the composition of the DCM fraction is warranted.

Calystegia soldanella Extract Exerts Anti-Oxidative and Anti-Inflammatory Effects via the Regulation of the NF-κB/Nrf-2 Pathways in Mouse Macrophages. Antioxidants (Basel) 2021; 10:antiox10101639. [PMID: 34679773 PMCID: PMC8533082 DOI: 10.3390/antiox10101639] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2021] [Revised: 10/11/2021] [Accepted: 10/13/2021] [Indexed: 11/17/2022] Open
Abstract
Plant polyphenols are widely used to treat various inflammatory diseases, owing to their ability to suppress reactive oxygen species production and the expression of inflammatory cytokines. Herein, we investigated phenolic compounds from Calystegia soldanella using UPLC Q-TOF MS/MS and their antioxidative and anti-inflammatory activities were analyzed. The C. soldanella ethyl acetate fraction (CsEF) had the strongest antioxidative activity, given its high polyphenol compound content. It also exhibited anti-inflammatory effects, inhibiting the production of inflammatory cytokines such as NO, PGE2, IL-1β, IL-6, and TNF-α in LPS-stimulated mouse macrophages. CsEF activated the nuclear transcription factor Nrf-2, thereby upregulating antioxidant enzymes such as HO-1 and NQO-1 and inhibiting NF-κB expression, which in turn, suppressed the expression of COX-2, iNOS, and inflammatory cytokines, ultimately exerting anti-inflammatory effects. Further, UPLC-Q-TOF-MS/MS was used to analyze the polyphenol compound contents in CsEF. The quercetin glycosides isoquercitrin and quercitrin were the primary flavonoid compounds, while the caffeic acid derivatives, chlorogenic acid and dicaffeoylquinic acid, were the primary phenolic acids. Thus, C. soldanella, which had only a limited use thus far as a medicinal plant, may serve as a natural medicinal resource for treating inflammatory diseases.

Abstract
Jejubacter calystegiae KSNA2T, a moderately halophilic, endophytic bacterium isolated from beach morning glory (Calystegia soldanella), was determined to be a novel species in a new genus in the family Enterobacteriaceae. To gain insights into the genetic basis of the salinity stress response of strain KSNA2T, we sequenced its genome using two complementary sequencing platforms (Illumina HiSeq and PacBio RSII). The genome contains a repertoire of metabolic pathways, such as those for nitrogen, phosphorus, and some amino acid metabolism pathways. Functional annotation of the KSNA2T genome revealed several genes involved in salt tolerance pathways, such as those encoding sodium transporters, potassium transporters, and osmoprotectant enzymes. Plant growth-promoting bacteria-based experiments indicated that strain KSNA2T promotes the germination of vegetable seeds in saline conditions. Overall, the genetic and biological analyses of strain KSNA2T provide valuable insights into bacteria-mediated salt tolerance in agriculture.

Abstract
BACKGROUND Newer drugs are in demand for leukemia treatment that specifically targets tumor cells without affecting normal cells. Potent cytotoxic activities have been reported from various parts of Zanthoxylum rhetsa. Thus, the present study was conducted to evaluate antileukemic potential of leaf extract of Z. rhetsa along with probable mechanism of cytotoxicity. Materials and Methods: The antiproliferative activity of the extract on leukemic cell lines was evaluated using sulforhodamine B assay. The changes in cell death profile, cell cycle, and expression levels of pro-apoptotic markers (p53, Bax, cytochrome C, caspase 3, and MMP) and antiapoptic marker (Bcl2) on Jurkat cell lines were studied using flow cytometer. Comparison of oxidative stress induced by extract on Jurkat cells and normal mouse fibroblast cells was done. DNA fragmentation was studied using gel electrophoresis. Results: The leaf extract showed concentration-dependent cytotoxicity against Jurkat cell lines majorly via apoptotic mechanism. It arrested cells at G0/G1 and S phase of cell cycle. Apoptosis was associated with increase in the expression of pro-apoptotic markers and decrease of anti-apoptotic markers. The treatment with extract selectively increased the oxidative stress in Jurkat cells and showed DNA fragmentation. Conclusion: The methanol extract of leaves of Z. rhetsa show selective cytotoxic activity on Jurkat cell lines and induced apoptosis via intrinsic pathway.

Abstract
We have previously shown that the transcript levels of Vegfc and its receptor Vegfr3 were high in spermatogonia and extremely low in spermatocytes and spermatids. However, it remains unknown about the functions and the mechanisms of VEGFC/VEGFR3 signaling in regulating the fate determinations of spermatogonia. To this end, here we explored the role and signaling pathways of VEGFC/VEGFR3 by using a cell line derived from immortalized mouse spermatogonia retaining markers of mitotic germ cells, namely GC-1 cells. VEGFR3 was expressed in mouse primary spermatogonia and GC-1 cells. VEGFC stimulated the proliferation and DNA synthesis of GC-1 cells and enhanced the phosphorylation of PI3K-AKT and MAPK, whereas LY294002 (an inhibitor for AKT) and CI-1040 (an inhibitor for MAPK) blocked the effect of VEGFC on GC-1 cell proliferation. Furthermore, VEGFC increased the transcripts of c-fos and Egr1 and protein levels of cyclin D1, PCNA and Bcl-2. Conversely, the blocking of VEGFC/VEGFR3 signaling by VEGFR3 knockdown reduced the phosphorylation of AKT/MAPK and decreased the levels of cyclin D1 and PCNA. Additionally, VEGFR3 knockdown not only resulted in more apoptosis of GC-1 cells but also led to a decrease of Bcl-2 and promoted the cleavage of Caspase-3/9 and PARP. Collectively, these data suggested that VEGFC/VEGFR3 signaling promotes the proliferation of GC-1 cells via the AKT /MAPK and cyclin D1 pathway and it inhibits the cell apoptosis through Caspase-3/9, PARP and Bcl-2. Thus, this study sheds a novel insight to the molecular mechanisms underlying the fate decisions of mammalian spermatogonia.

The comparative study among different fractions of muscadine grape 'Noble' pomace extracts regarding anti-oxidative activities, cell cycle arrest and apoptosis in breast cancer. Food Nutr Res 2017; 61:1412795. [PMID: 29249924 PMCID: PMC5727431 DOI: 10.1080/16546628.2017.1412795] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2017] [Accepted: 11/29/2017] [Indexed: 11/19/2022] Open
Abstract
As a by-product of wine making, pomace contains rich amounts of phenolic compounds that can be potentially utilized as raw materials to make beneficial products especially for the anti-cancer agents including the breast cancer. Muscadinia rotundifolia ‘Noble’ is a wine-making grape cultivar, and to better use ‘Noble’ pomace, the most effective phenolic fractions in cancer inhibition must be identified. In this study, anti-oxidative activities of three separated fractions of ‘Noble’ pomace (F1, F2 and F3) were compared in 2,2-diphenyl-1-picrylhydrazyl and 2,2ʹ-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid) radical scavenging (DPPH and ABTS) assays as well as the ferric-reducing antioxidant power (FRAP) assay. The ability of different fractions to induce cell cycle arrest and apoptosis in MDA-MB-231 breast cancer cells was also evaluated by flow cytometry and Western blot analysis. Fraction F3, which contained a mixture of anthocyanidins and ellagic acids, exhibited the strongest anti-oxidative activity, as determined at both low and high concentrations in the DPPH and FRAP assays. F3 also demonstrated the greatest ability to induce apoptosis via caspase activation and cell cycle arrest by downregulating cyclin A and upregulating p21. F3 was thus the most effective bioactive fraction among those prepared from muscadine grape ‘Noble’ pomace.

Abstract
Numerous laboratory and epidemiological studies show that the risk of developing several types of cancer can be reduced with the employment of natural substances that act with multiple mechanisms. In this context, an important role is played by the isothiocyanates. Recently, 6-(methylsulfonyl)hexyl isothiocyanate (6-MITC), present in the root of Wasabia Japonica, has stimulated the interest of researchers as a chemopreventive agent. In this particular study we have focused on evaluating 6-MITC’s in vitro cytotoxic, cytostatic and cytodifferentiating activities, as well as its pro-apoptotic potential. These effects were investigated by way of flow cytometric analysis of Jurkat and HL-60 cells as well as of healthy lymphocytes extracted from the blood of AVIS donors, in order to verify a potential selectivity of action. The results demonstrate that 6-MITC exerts a stronger cytotoxic effect on tumour cells than on healthy cells. The apoptosis induction exerted by 6-MITC on transformed cells is triggered by an extrinsic pathway, as demonstrated by the statistically significant increase in the percentage of cells with activated caspase-8. It was also observed that 6-MITC is able to limit tumour growth by slowing down and blocking the cell cycle of Jurkat and HL-60 cells respectively, in a dose- and time-related manner, while exerting no activity of any kind on the replication of healthy cells. Finally, by measuring the expression levels of CD-14 and CD-15, 6-MITC showed the ability to induce cytodifferentiation of HL-60 cells into macrophage and granulocytic phenotypes.

Abstract
The lipase-catalyzed polymerization of N-methyldiethanolamine, diethyl sebacate and ω-pentadecanolide was performed to construct a cationic poly(amine-co-ester), and a hydrophobic N-(2-bromoethyl)carbamoyl cholesterol was then grafted onto its main chain through a quaternization reaction to prepare the amphiphilic copolymer Chol-g-PMSC-PPDL. The copolymer efficiently bound and condensed miR-23b to form stable nanocomplexes, which showed favorable cellular uptake and miR-23b transfection efficacy due to the introduction of the hydrophobic segment. After miR-23b delivery, an obvious inhibition of cell proliferation could be induced, which was attributed to the induction of cell apoptosis and cell cycle arrest. Moreover, the carrier-mediated miR-23b delivery could inhibit the migration and invasion of tumor cells. Overall, the work provides a novel chemoenzymatic strategy for constructing biodegradable and biocompatible poly(amine-co-ester) derivatives, which are promising carriers for oligonucleotide delivery to achieve tumor gene therapy.

Abstract
BACKGROUND Some studties reported that the polymorphism of TM6SF2 gene E167K affects the occurrence and the progression of hepatocytes carcinoma (hepatocellular, HCC). In oeder to investigate the effects of the polymorphism of TM6SF2 gene E167K in the pathogenesis of HCC, we explored its influence on the cell cycle in hepatocellular carcinoma cell HEPA1-6. METHODS HEPA 1-6 cells which could respectively overexpress TM6SF2 wild type and E167K variant were cultured and HEPA 1-6 cells with zero load plasmids were used as matched control. Flow cytometry was used to detect the cell cycles of these 3 type of HEPA 1-6 cells. Realtime fluores-cence quantitative PCR and western blot were used to analyzed the expression of regulatory factors (Cyclin D1、p53、P16、P27、P21 and Rb) of cell cycle. T-test was used in statistical analysis. RESULTS Cell cycle phase distribution was presented by the proportion of cells in each phases (%). Compared with the control group, the cell cycle phase distribution (G1 phase 57.36 ± 0.21%, G2/M phase 25.61 ± 0.36%,S phases 19.31 ± 0.25%) had no differences in wild type group (G1 phase 57.63 ± 0.28%, G2/M phase 25.77 ± 0.51%, S phases 19.54 ± 0.25%; P < 0.05). Between variant type group and wild type group,G1 phase was significantly decreased (variant type group G1 phase 36.26 ± 0.31%, P < 0.05),S phase and G2/M phase were increased(variant type group S phase 28.41 ± 0.31%, P < 0.05;G2/M phase 35.23 ± 0.14%, P < 0.05), respectively. Compared with control group,the relative expression of CyclinD1、P53 and Rb mRNA in variant type group was significantly upregulated (2.03 ± 0.01 VS 1.04 ± 0.06, 1.88 ± 0.05 VS 1.37 ± 0.03, 1.29 ± 0.06 VS 1.15 ± 0.03, P < 0.05) and P27 mRNA in variant type group was significantly downregulated (0.56 ± 0.02 VS 0.85 ± 0.05, P < 0.05). Compared with wild type group, the relative expression of CyclinD1、P53 and Rb mRNA in variant type group was significantly upregulated (wild type group 1.00 ± 0.00, 1.48 ± 0.09, 1.18 ± 0.01, P < 0.05) and P27 mRNA in variant type group was significantly downregulated (variant type group 0.82 ± 0.05,P < 0.05). There was no statistical significance between wild type group and control group (P > 0.05). P16 and P21 expression showed no statistical sigtfificance in any of these three groups (P > 0.05). CONCLUSION E167K polymorphism of TM6SF2 gene affects cell cycles of HEPA1-6 cells via up-regulating CyclinD1、P53 and Rb and down-regulating P27.
