Evaluation of oyster mushroom (Pleurotus ostreatus)-derived anthraquinone on the induction of apoptosis and suppression of MMP-2 and MMP-9 expression in breast cancer cells.

Introduction: Breast cancer results from tissue degradation caused by environmental and genetic factors that affect cells in the body. Matrix metalloproteinases, such as MMP-2 and MMP-9, are considered potential putative markers for tumor diagnosis in clinical validation due to their easy detection in body fluids. In addition, recent reports have suggested multiple roles for MMPs, rather than simply degeneration of the extracellular matrix, which comprises mobilizing growth factors and processing surface molecules. Methods: In this study, the chemotherapeutic effects of anthraquinone (AQ) extracted from edible mushrooms (Pleurotus ostreatus Jacq. ex Fr.) cells was examined in MCF-7 breast cancer cells. The cytotoxic potential and oxidative stress induced by purified anthraquinone were assessed in MCF-7 cells using MTT and ROS estimation assays. Gelatin Zymography, and DNA fragmentation assays were performed to examine MMP expression and apoptotic induction in the MCF-7 cells treated with AQ. The genes crucial for mutations were examined, and the mutated RNA knockout plausibility was analyzed using the CRISPR spcas9 genome editing software. Results: MCF-7 cells were attenuated in a concentration-dependent manner by the administration of AQ purified from P. ostreatus compared with the standard anticancer drug paclitaxel. AQ supplementation decreased oxidative stress and mitochondrial impairment in MCF-7 cells. Treatment with AQ and AQ with paclitaxel consistently decreased the expression of crucial marker genes such as MMP2 and MMP9. The mutated genes MMP2, MMP7, and MMP9 were assessed and observed to reveal four putative gene knockdown potentials for breast cancer treatment. Conclusions: The synergistic application of AQ and paclitaxel exerted a strong inhibitory effect on the MCF-7 breast cancer cells. Extensive studies are imperative to better understand the action of bioactive mixes on the edible oyster fungus P. ostreatus. The gene knockout potential detected by CRISPR SpCas9 will aid in elite research into anticancer treatments.

The Role of Stem Cell Therapies in the Treatment of Neurodegenerative Diseases.

Cellular replacement therapy and genetic transfer in injured brains provide new pathways for treating human neurological illnesses. Current progress in the field focuses on the production of neurons and glial cells from many types of stem cells, such as embryonic, induced pluripotent, mesenchymal, and neural stem cells. This has led to a significant increase in research on brain transplantation treatments. Extended neurodegeneration results in the progressive decline of certain neuronal subtypes or whole neuronal cells. An analysis of the progress made in induced pluripotent and mesenchymal stem cells reveals their significant promise in disease modeling, regeneration, and medication screening. The requirement for stem cells in neurodegenerative disease studies has been crucial in recent years. Stem cells provide the potential for replacing impaired neurons, comprehending disease needs modeling, and creating efficient treatments, but they have many challenges in culturing and acceptability to the host immune cells. The need to use their potential in discovering novel therapies for diseases such as Alzheimer's, Parkinson's, and amyotrophic lateral sclerosis leads to promising therapy. This review examines the function of stem cells in the pathogenesis and treatment of Huntington's disease, Parkinson's disease, Alzheimer's disease, and multiple sclerosis. This review further examines hurdles such as immunological reactions and delivery systems intending to overcome these problems. This article offers a detailed viewpoint on the use of stem cell-based nanotherapies as revolutionary treatments for various neurological illnesses.

Bioactive Components and Health Potential of Endophytic Micro-Fungal Diversity in Medicinal Plants.

The endophytic fungi that reside inside medicinal plants have the potential to produce various pharmaco-potential bioactive compounds. The endophytic fungi Graminicolous helminthosporium, Bipolaris australiensis and Cladosporium cladosporioides were isolated from different medicinal plants. The GC-MS analysis of intra- and extracellular products of endophytic fungi revealed the presence of various bioactive metabolites, such as Anthracene, Brallobarbital, Benzo [h] quinolone, Ethylacridine, 2-Ethylacridine, Cyclotrisiloxane, 5 methyl 2 phenylindolizine, and 1,4-Cyclohexadien-1-one, etc. The phytochemical composition analysis of endophytic fungus extracts also revealed the presence of flavonoids, phenols, saponins, carbohydrates, glycosides, and proteins. The intra- and extracellular endophytic extracts exhibited strong antibacterial and antioxidant activity, which was screened with the agar-well diffusion method and DPPH, H2O2, and nitric oxide scavenging activity, respectively. The bioactive compounds identified in the endophytic extracts from GC-MS profiling served as ligands for molecular-docking analysis to investigate the anticancer potential against non-small cell lung carcinoma receptor EGFR. Molecular docking results showed that compounds, such as Brallobarbital, and 5 methyl 2 phenylindolizine had the lowest E- min values, which suggests that these compounds could be used in anticancer drug development. Thus, the isolated endophytic fungal species can be used to produce various bioactive compounds that could be used in novel drug development from natural sources and reduce the environmental burden of synthetic chemical drugs.

Evaluation of Therapeutic Potential of Eugenol-A Natural Derivative of Syzygium aromaticum on Cervical Cancer

Background: The intendment of this study is to determine the pursuance in ­ vitro anticancer activity and cytotoxicity of Syzygium aromaticum against the human cervical cancer cell line (HeLa) compared to the normal cell lines. Apoptogenic properties of DCM extract of Eugenol was determined in this entire study. Materials and Methods: HeLa cell lines were cultured in DMEM medium and incubated with different concentration of DCM ­ Eugenol extract. MTT assay brought out the way to determine the cell viability and quantification was done with the optical absorbance at 570 nm and 620 nm as reference. Apoptotic cells were affirmed by dual staining using acridine orange bromide. Besides, the morphology of the nucleus was also confirmed by dual staining. Eugenol inhibited 50% growth (IC50) of HeLa cell lines at 200 mg/ml of extract concentration. Results: Inhibitory efficacy of eugenol isolated from Syzyzgyium aromaticum showed the cell ­ viability in time and dose dependent manner with consistent morphological changes. Flow cytometer determined the apoptosis confirming the cytotoxicity value for MTT at IC50 with 81.85% cell viability. Dual staining firmly enacts the damaged cells due to AO indicating apoptosis confirmation by dual staining. Morphological analysis also clearly states that nil apoptosis has been seen in control and similarly in eugenol treated when compared to cancerous HeLa cell ­ line. Conclusion: Evaluation of cytotoxicity effect of eugenol isolated from Syzygium aromaticum showed it can be unrivalled dormant source of prodigious changes in HeLa cell line indicating (revealing) that chemotherapeutic agent.

Extraction and Characterization of Chick PEA (Cicer arietinum) Extract with Immunostimulant Activity in BALB/C MICE

Traditional plant medicines are used for a range of cancer conditions. The chickpea is highly proteinaceous and consumed as a staple in many parts of the world. An evaluation of chemoprotective and immunomodulatory activities of Cicer arietinum (CE) in cisplatin-induced immunosuppressed mice was here performed. Cisplatin was given at 100mg/kg, intraperitoneally, and after induction of immunosuppression mice were treated with Cicer arietinum (0.5 mg/dose/animal/IP) for a period of 10-day. The influence of the extract on lymphoid organ weight, bone marrow cellularity, alpha esterase activity and on enzyme levels such as (SGOT,SGPT, Urea, Creatinine was assessed to identify any chemoprotective influence. Administration of CE to cisplatin-treated mice alleviated the drastic reduction in bone marrow cellularity and α- esterase positive cells seen with cisplatin. Thus myelosuppression was reversed or inhibited. Cisplatin bids to DNA and causes damage resulting in chromosome breaks, micronucleus formation and cell death. CE is comprised of numerous middle-chain aliphatic alcohols, aldehydes and ketones, in addition to compounds like 7-hydroxy-1-methoxy-6-methylanthraquinone, cyclohexadecane (CAS) and 6-(amino methyl)-2-naphthol. These latter are thought to contribute to the characteristic aroma of C. arietimnum. In conclusion, administration of CE in cisplatin-treated mice, boosted bone marrow cellularity and increased α- esterase positive cells, thus reversing myelosupproession.
