[PMID: 37114286 DOI: 10.1002/jbt.23378] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 02/16/2023] [Accepted: 04/14/2023] [Indexed: 04/29/2023]
Abstract
Poly-L-lysine (PLL) is known to be an encapsulating agent in drug formulation and delivery. PLL also has apoptotic and antiproliferative activities that enable blocking of the tumorigenesis process. However, the dose-selective activities of PLL in exerting apoptosis against cancer are unclear. Therefore, this study has been designed to explore the potential role and dose of PLL in apoptosis, if any. For this, PLL was administered at several doses in cancer cell lines and was found to be more potent against MCF-7 cells. PLL causes mitochondria-mediated apoptotic death through the upregulation of cleaved caspase-3. To investigate the mechanism responsible for this activity, we have analyzed if PLL could have the DNA interactive property or not. For this, molecular docking analysis was carried out to prove whether it has the property to bind with DNA or not. Studies have revealed that PLL is a potent DNA binder and it probably performs such apoptotic activities through the binding of cellular DNA early in an exposure. Simultaneous upregulation of both ROS-mediated stress and also in key protein expressions like γ-H2AX could also help us to confirm that PLL induces apoptosis through DNA interaction. This finding leads us to believe that PLL could play an interfering role with other chemotherapeutic compounds when used as a drug-coating material as it exerts an apoptotic effect on cancer cells, which should be avoided by using a much lower concentration.

Moringa oleifera L. leaf extract induces cell cycle arrest and mitochondrial apoptosis in Dalton's Lymphoma: An in vitro and in vivo study. JOURNAL OF ETHNOPHARMACOLOGY 2023; 302:115849. [PMID: 36306933 DOI: 10.1016/j.jep.2022.115849] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Revised: 10/14/2022] [Accepted: 10/15/2022] [Indexed: 06/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The present work is based on a wide spectrum of evidences available from scientific literature which reflects nutritional and medicinal values of natural products such as plants and their extracts. Moringa oleifera is one such popular plant species amidst indigenous tribal communities which is frequently used to treat ailments such as piles, sore throat, eye and ear infections and even poisonous bites of tropical fauna such as insects or snakes. Furthermore decoction of leaf and bark was used to cure fever and cough. Evidences further reveal that Moringa oleifera L. (Family Moringaceae), is widely distributed not only over the Indian sub-continent, but also over Philippines, Central America, Saudi Arabia and the Caribbean Islands and have been traditionally used to treat cancers since ancient times. However, therapeutic effects of Moringa oleifera on Non-Hodgkin Lymphoma (NHL) are yet to be established. AIM OF THE STUDY The study aims to investigate the anti-cancer effects of Moringa oleifera leaf extract against murine NHL Non-Hodgkin cells in vitro and in vivo. MATERIAL AND METHODS The pharmacologically active compounds of Moringa oleifera leaf extract were identified by GC-HRMS analysis. Tests of Moringa oleifera leaf extract's cytotoxicity against DL cells were carried out using the MTT assay. Chromatin condensation along with other morphological alterations were visualized through Fluorescence microscopy. Changes in the mitochondrial membrane potential (ΔΨm), the cell cycle, and apoptosis were analysed through flow cytometer. We tried to identify proteins involved in apoptosis and cell cycle through Western blotting using BALB/c mice as a model organism. RESULTS GC-HRMS study revealed that a methanol based leaf extract of Moringa oleifera (MOML) comprises of a variety of bioactive chemicals. Our results indicate that MOML successfully reduced the proliferation of DL cells by lowering ΔΨm, changing overall cell morphology. DL cells treated with MOML showed arrested cell cycle at the G2/M phase and substantially up-regulated the expression of p53 and p21. Elevated levels of Bax, Cyt-c, and Caspase-3 and lowered expression levels of Bcl-2 protein suggested induction of apoptosis. Mechanistically, the anticancer efficacy of MOML is attributed to MEK/ERK-mediated pathway inactivation in DL cells. It is also interesting to note that MOML-mediated inhibition of DL growth was accompanied by apoptosis induction and improvement in hematological parameters in DL-bearing mice. CONCLUSION Our finding suggested that MOML induces apoptosis and abrogates the growth of Dalton's lymphoma both in vitro and in vivo.

Platycodin D Inhibits Vascular Endothelial Growth Factor-Induced Angiogenesis by Blocking the Activation of Mitogen-Activated Protein Kinases and the Production of Interleukin-8. THE AMERICAN JOURNAL OF CHINESE MEDICINE 2022; 50:1645-1661.

Abstract
Platycodin D is a major constituent in the root of Platycodon grandiflorum and has diverse pharmacologic activities, including anti-inflammatory, anti-allergic, and antitumor activities. Vascular endothelial growth factor (VEGF) and interleukin-8 (IL-8) are potent angiogenic factors and contribute to tumor angiogenesis by directly and indirectly promoting angiogenic processes, including the proliferation, adhesion, migration, and tube formation of endothelial cells. Here, we found that platycodin D at noncytotoxic concentrations inhibited VEGF-induced proliferation, adhesion to the extracellular matrix proteins fibronectin and vitronectin, chemotactic motility, and tube formation of human umbilical vein endothelial cells (HUVECs). Platycodin D reduced the phosphorylation of extracellular signal-regulated kinase (ERK), p38, and c-Jun N-terminal kinase (JNK) and the secretion of IL-8 in VEGF-stimulated HUVECs. Moreover, platycodin D inhibited tube formation and the phosphorylation of ERK and p38 in IL-8-stimulated HUVECs. The in vitro anti-angiogenic activity of platycodin D was confirmed by in vivo experimental models. Platycodin D inhibited the formation of new blood vessels into mouse Matrigel plugs with VEGF or IL-8. In mice injected with MDA-MB-231 human breast cancer cells, orally administered platycodin D inhibited tumor growth, the number of CD34 [Formula: see text]vessels, and the expression of VEGF and IL-8. Taken together, platycodin D directly and indirectly prevents VEGF-induced and IL-8-induced angiogenesis by blocking the activation of mitogen-activated protein kinases (MAPKs). Platycodin D may be beneficial for the prevention or treatment of tumor angiogenesis and angiogenesis-related human diseases.

[PMID: 33771640 DOI: 10.1016/j.jep.2021.114060] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Revised: 03/06/2021] [Accepted: 03/18/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Epidemiological studies promote the inclusion of natural-products in diet due to their inhibitory effects on various types of cancer. Among them, Achyranthes aspera L. (Family Amaranthaceae) is a medicinal plant in Ayurvedic pharmacopeia, found in India, Southeast Asia, America, and Sub-Saharan Africa. It is endowed with anti-inflammatory, anti-oxidant, and anti-cancer activities. However, its potential effect on Non-Hodgkin lymphomas (NHLs), has not yet been clarified. AIM OF THE STUDY In the present study, we aimed to investigate the effect of Achyranthes aspera L. leaf extracts on highly aggressive murine NHL called Dalton's Lymphoma (DL) in vitro and in vivo. MATERIAL AND METHODS GC-HRMS analysis was carried out for the identification of compounds present in A. aspera leaf extract. The cytotoxicity of various A. aspera leaf extracts was evaluated on DL cells by MTT assay. Chromatin condensation, nuclear fragmentation, and morphological changes were observed by microscopy technique. Flow cytometry was used to measure the changes in mitochondrial membrane potential (ΔΨm) and apoptosis. In addition, the expressions of apoptosis-related proteins were detected by western blotting. Meanwhile, the in vivo anti-tumor effect of leaf extract was tested in DL induced Balb/c mice. RESULT GC-HRMS analysis of A. aspera methanolic leaf extract (AAML) revealed the presence of ten pharmacologically active compounds. The results showed that AAML suppressed cell proliferation, decreased mitochondrial membrane potential, changed the morphological structure, and induced apoptosis. Moreover, AAML could promote the release of cytochrome c by regulating Bcl-2 family proteins and then activated caspase-9/ -3 to triggered cell apoptosis. At the same time in DL cells treated with AAML, the protein kinase Cα (PKCα) pathway was inhibited in a concentration-dependent manner. Remarkably, in vivo, AAML mediated suppression of DL growth in Balb/c mice was accompanied by attenuation of the PKCα pathway and induction of apoptosis. Our result suggested that AAML promotes mitochondrial apoptotic cascade in DL cells by suppressing the PKCα signaling pathway. CONCLUSION The study suggests that AAML could potently suppress DL progression by promoting apoptosis via mitochondrial-cascade and attenuation of the PKCα signaling pathway.

Abstract
Cancer is a widespread disease that has shown promising mortality worldwide. Our previous study has been shown the efficacy of Poly-l-lysine (PLL) as a promising cytotoxic effect against cancer cells. However, exact-mechanism of PLL in 3D physiological relevant tumor-microenvironment and against tumor-angiogenesis has never been analysed. In this study, we have investigated apoptotic efficacy of PLL, if any in opposition to proliferative aggressive cancer cell MDA-MB-231 both 2D and-3D cell culture conditions. Furthermore, PLL was administered in B16F10 murine melanoma cells induced BALB/c mice model. The study has been designed through transcription and translation level of PLL-induced tumor-angiogenesis and apoptotic gene-expression modulation level and various relevant histological studies in comparison with untreated control. Studies have shown anti-proliferative and anti-tumor angiogenic efficacy of PLL better in in-vitro 3D tumor-microenvironment against MDA-MB-231 breast cancer cells. Furthermore, in-vivo model, PLL was found to suppress tumorigenesis process at minimum dose. PLL found to induce apoptosis through-upregulation of cytosolic-cytochrome-C, caspase-3 and PARP activations when administered in B16F10 induced in-vivo tumor. In blocking proliferation and tumor-angiogenesis, PLL was found to be effective as it significantly downregulated activity of VEGF, VEGFR2, Ki-67 and c-Myc expression. As PLL blocked tumor progression and induced DNA-break, also upregulated apoptotic process and recovered tissue architecture as revealed from histological study in comparison with untreated control. Overall PLL was found to be a promising anti-tumor angiogenic and anti-proliferative drug that was effective both in in-vitro breast cancer 3D tumor-microenvironment and in-vivo metastatic-mice-model.

Anti-Tumor Efficiency of Perillylalcohol/β-Cyclodextrin Inclusion Complexes in a Sarcoma S180-Induced Mice Model. Pharmaceutics 2021; 13:pharmaceutics13020245.

Abstract
The low solubility and high volatility of perillyl alcohol (POH) compromise its bioavailability and potential use as chemotherapeutic drug. In this work, we have evaluated the anticancer activity of POH complexed with β-cyclodextrin (β-CD) using three complexation approaches. Molecular docking suggests the hydrogen-bond between POH and β-cyclodextrin in molar proportion was 1:1. Thermal analysis and Fourier-transform infrared spectroscopy (FTIR) confirmed that the POH was enclosed in the β-CD cavity. Also, there was a significant reduction of particle size thereof, indicating a modification of the β-cyclodextrin crystals. The complexes were tested against human L929 fibroblasts after 24 h of incubation showing no signs of cytotoxicity. Concerning the histopathological results, the treatment with POH/β-CD at a dose of 50 mg/kg promoted approximately 60% inhibition of tumor growth in a sarcoma S180-induced mice model and the reduction of nuclear immunoexpression of the Ki67 antigen compared to the control group. Obtained data suggest a significant reduction of cycling cells and tumor proliferation. Our results confirm that complexation of POH/β-CD not only solves the problem related to the volatility of the monoterpene but also increases its efficiency as an antitumor agent.

Abstract
The aim was to develop oral site-specific rate-controlled anticancer drug delivery to pacify systemic side-effects and offer effective and safe therapy for colon cancer with compressed dose and duration of treatment. The double emulsion solvent evaporation method was employed. To check functionality, DAPI-staining and in-vivo anticancer study of Ehrlich Ascites Carcinoma bearing mice was tested. Histopathology of liver and kidney and Cell morphology of EAC cell was also performed. Formulated and optimized polymeric microsphere of 5-FU showed excellent physicochemical features. In-vitro, DAPI results pointed drug-treated groups displayed the prominent feature of apoptosis. The percentage of apoptotic of entrapped drug played in a dose-dependent manner. Significant decreases in EAC liquid tumors and increased life span of treated mice were observed. Rate of variation of cell morphology was more in 5-FU loaded microsphere than 5-FU injection. Hematological and biochemical parameter's and Histopathology of liver and kidney resulted that due to control released formulation have slow release rate, that gives less trace on liver and kidney function. Finally, we foresee that polymeric microsphere of 5-FU applying natural gum katira could be an assuring micro-carrier for active colon targeting delivery tool with augmented chemotherapeutic efficacy and lowering side effect against colon cancer.

Abstract
Male germline stem cells (mGSCs) can transmit genetic materials to the next generation and dedifferentiate into pluripotent stem cells. However, in livestock, mGSC lines are difficult to establish, because of the factors that affect their isolation and culture. The extracellular matrix serves as a substrate for attachment and affects the fate of these stem cells. Poly-L-lysine (PL), an extracellular matrix of choice, inhibits and/or kills cancer cells, and promotes the attachment of stem cells in culture. However, how it affects the characteristics and potentials of these stem cells in culture needs to be elucidated. Here, we isolated, enriched and cultured dairy goat mGSCs on five types of extracellular matrices. To explore the best extracellular matrix to use for culturing them, the characteristics and proliferation ability of the cells were determined. Results showed that the cells shared several characteristics with previously reported mGSCs, including the poor effect of PL on their proliferative and colony-forming abilities. Further examination showed upregulation of p53 expression in these cells, which could be inhibiting their proliferation. When a p53 inhibitor was included in the culture medium, it was confirmed to be responsible for the inhibition of proliferation in mGSCs. Optimal concentration of the inhibitor in the culture of these cells was 5 µM. Furthermore, addition of the p53 inhibitor increased the expression of the markers of self-renewal and cell cycle in goat mGSCs. In summary, suppressing p53 is beneficial for the proliferation of dairy goat mGSCs, cultured on PL.
