IntroductionIn the present study, we decided to prepare and formulate a new chemotherapeutic drug (silver nanoparticles in ‎aqueous medium using Salvia officinalis leaf aqueous extract) for the treatment of human ovarian cancer in the in ‎vitro condition.Material and methodsThe organometallic chemistry tests such as Scanning Electron Microscopy (SEM), UV–Visible Spectroscopy ‎‎(UV-Vis), and Fourier Transformed Infrared Spectroscopy (FT‐IR) were used for characterizing of silver ‎nanoparticles. For investigating the antioxidant potentials of AgNO3, Salvia officinalis aqueous extract, and ‎silver nanoparticles, the DPPH test was used in the presence of butylated hydroxytoluene as the positive ‎control. To survey the cytotoxicity and anti-human ovarian cancer activities of AgNO3, Salvia officinalis ‎aqueous extract, and silver nanoparticles, MTT assay was used on the human ovarian cancer cell lines i.e., Caov-‎‎3‎, SK-OV-3, and PA-1‎. ‎ResultsIn UV-Vis, the clear peak in the wavelength of 421 nm indicated the formation of silver nanoparticles. In FT-IR ‎test, the presence of many antioxidant compounds with related bonds caused the excellent condition for ‎reducing of silver in the silver nanoparticles. The silver nanoparticles inhibited half of the DPPH molecules in ‎the concentration of 251 µg/mL. The best result of anti-human ovarian cancer effects of silver nanoparticles ‎against the above cell lines was observed in the case of the SK-OV-3 cell line. ‎ConclusionsSilver nanoparticles had very low cell viability and anti-human ovarian cancer properties dose-dependently ‎against Caov-3‎, SK-OV-3, and PA-1 cell lines without any cytotoxicity on the normal cell line (HUVECs). ‎

Introduction MicroRNAs (miRs) exhibit the potential to act as therapeutic targets for the management of human cancers including ovarian cancer. The role of microRNA-30 (miR-30) via modulation of RAB32 expression has not been studied in ovarian cancer. Consistently, the present study was designed to characterize the molecular role of miR-30/RAB32 axis in human ovarian cancer. Methods Cell viability was determined by MTT assay. Expression analysis was carried out by qRT-PCR. Dual luciferase assay was used to confirm the interaction between miR-30 and RAB32. Scratch-heal and transwell chamber assays were used to monitor the cell migration and invasion. Western blotting and immunofluorescence assays were used to determine the protein expression. Results The results revealed significant ( p < 0.05) downregulation of miR-30 in human ovarian cancer cell lines. Overexpression of miR-30 in ovarian SK-OV-3 and A2780 cancer cells significantly ( p < 0.05) inhibited their proliferation. Besides, ovarian cancer cells overexpressing miR-30 showed significantly ( p < 0.05) lower migration and invasion. The miR-30 upregulation also altered the expression pattern of marker proteins of epithelial–mesenchymal transition in ovarian cancer cells. In silico analysis predicted RAB32 as the molecular target of miR-30 at post-transcriptional level. The silencing of RAB32 mimicked the tumor-suppressive effects of miR-30 overexpression in ovarian cancer cells. Nonetheless, overexpression of RAB32 could prevent the tumor-suppressive effects of miR-30 on SK-OV-3 and A2780 cancer cells. Conclusion Taken together, the results suggest the tumor-suppressive role of miR-30 and point towards the therapeutic utility of miR-30/RAB32 molecular axis in the management of ovarian cancer

IntroductionRecently, various nanoparticles containing medicinal plants have been specifically designed to deliver anticancer drugs and nucleic acids such as DNA and RNA to cancer cells and as a result, they open up new avenues in cancer treatment strategies. In this study, gold nanoparticles were synthesized in aqueous medium using Nigella damascena extract as ‎stabilizing and reducing agents. ‎Material and methodsThe synthesized nanoparticles (AuNPs) were characterized using different techniques including UV-Vis. and ‎FT-IR spectroscopy, and Transmission electron microscopy (TEM). TEM images exhibited a uniform spherical ‎morphology in size of 21.64 nm for the biosynthesized nanoparticles. In the cellular and molecular part of the ‎recent study, the treated cells with AuNPs were assessed by MTT assay for 48h about the cytotoxicity and anti-‎human ovarian cancer ‎ properties on normal (HUVEC) and ovarian cancer cell lines i.e. PA-1, Caov-3, SW 626, ‎and SK-OV-3. ‎ResultsThe viability of malignant ovarian‎ cell line reduced dose-dependently in the presence of AuNPs. The IC50 of ‎AuNPs were 232‎, ‎204‎, ‎193‎, and ‎288 µg/mL against PA-1, Caov-3, SW 626, and SK-OV-3 cell lines, ‎respectively. In the antioxidant test, the IC50 of AuNPs and BHT against DPPH free radicals were 151 and 142 ‎‎µg/mL, respectively. ‎ConclusionsAfter clinical study, gold nanoparticles containing Nigella damascena leaf aqueous extract may be used to ‎formulate a new chemotherapeutic drug or supplement to treat the several types of human ovarian cancer.‎

IntroductionThe recent research showed that the Gold nanoparticles (GNPs) formulated with Nigella Sativa aqueous extract having potent antioxidant and anti-human ovarian cancer activities in vitro condition.Material and methodsFor determinate the properties of the GNPs that were produced from the reaction between gold chloride solution with aqueous Nigella Sativa extract, we used UV–Visible Spectroscopy (UV-Vis), Field Emission Scanning Electron Microscopy (FE‐SEM), Fourier Transformed Infrared Spectroscopy (FT‐IR), and Transmission Electron Microscopy (TEM). For evaluating anti-ovarian cancer and cytotoxicity effects of GNPs, Au chloride, and Nigella Sativa aqueous extract, we used MTT assay.ResultsThe result of this test showed that GNPs have no cytotoxicity on normal cell line (HUVEC) and have potent anti-ovarian cancer features dose-dependently against PA-1, SK-OV-3, and SW-626 cell lines. The IC50 of GNPs were 249, 361, and 433 µg/mL against PA-1, SW-626, and SK-OV-3 cell lines, respectively. For evaluating the antioxidant features of GNPs, Au chloride, and Nigella Sativa aqueous extract, we used the DPPH test, in this test butylated hydroxytoluene was a positive control, the results of this test showed that the GNPs have an effective antioxidant feature. In the antioxidant test, the IC50 of GNPs and BHT were 144 and 201 µg/mL, respectively.ConclusionsProbably, potent anti-human ovarian cancer activities of GNPs formulated with Nigella Sativa aqueous seed extract because of antioxidant properties. After evaluating the effectiveness of this formulation in clinical trial researches, it can be a good alternative to chemotherapy drugs.

IntroductionWe also investigated the Carpachromene in the cytotoxicity studies against common human ovarian cancer cell ‎line i.e., SW 626, in-vitro.Material and methodsCell viability of Carpachromene was very low against common ‎human ovarian cancer ‎cell line i.e. SW 626 without any cytotoxicity on normal cell line. To compare the ‎biological activities of molecules, the enzymes used are α-glucosidase, acetylcholinesterase, respectively. Finally, ‎calculations were made using the molecular docking method to compare the biological activity of the ‎carpachromene molecule. We then examined whether the release of Smac is necessary for apoptosis in ovarian ‎cancer cells using the SW 626‎ cell line. We first examined mitochondrial and cytosolic Smac levels after ‎Carpachromene treatment. ‎ResultsFollowing the docking calculations, the properties of the carpachromene molecule ‎were examined by ADME/T analysis in order to be used as a drug in the future. In addition, the anti-oxidant ‎properties of the molecules were examined in both gas and water phase with the HF/6-31g basis set with the ‎Gaussian software program. As shown, exposure of ovarian cancer cells to Carpachromene decreased ‎mitochondrial Smac and increased cytosolic Smac levels in a time-dependent fashion. As depicted in results, a ‎decrease in Smac expression was confirmed by Western blot. Silencing of Smac significantly inhibited ‎Carpachromene-induced caspase-3 cleavage and attenuated apoptosis in these cells Moreover, overexpression of ‎a Smac heptapeptide (Smac-N7) enhanced Carpachromene-induced cell deathConclusionsAccording to the above findings, the Carpachromene may be administrated for the treatment of several types of ‎human ovarian cancer in humans. ‎
