Chemical Characterization of Taif Rose (Rosa damascena) Methanolic Extract and Its Physiological Effect on Liver Functions, Blood Indices, Antioxidant Capacity, and Heart Vitality against Cadmium Chloride Toxicity

ABSTRACT: Exposure to cadmium chloride (CdCl2) causes an imbalance in the oxidant status of the body by triggering the release of reactive oxygen species (ROS). This study investigated the effect of Rosa damascena (R. damascena) extract on oxidative stress, hepatotoxicity, and the injured cardiac tissue of male rats exposed to CdCl2. Forty male Wistar albino rats were divided into four groups: the vehicle control (1 mg/kg normal saline), the CdCl2-treated group (5 mg/kg), the R. damascena extract group (100 mg Kg), and the combination of CdCl2 and R. damascena extract group. Male rats exposed to CdCl2 showed multiple significant histopathological changes in the liver and heart, including inflammatory cell infiltration and degenerative alterations. Successive exposure to CdCl2 elevated the levels of hepatic and cardiac reactive oxygen species (ROS), malondialdehyde (MDA), tumour necrosis factor-alpha) (TNF-α) and interleukin -6 (IL-6) and decreased antioxidant defences. The extracts significantly increased the levels of glutathione, superoxide dismutase (SOD), and catalase (CAT), whereas it dramatically decreased the levels of lipid peroxidation (LPO), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and the mRNA of TNF-α and IL-6. R. damascena administration prevented liver and heart injury; suppressed excessive ROS generation, LPO, and inflammatory responses; and enhanced antioxidant defences. In addition, R. damascena upregulated the mRNA of TNF-α and IL-6 in CdCl2-administered male rats. In conclusion, R. damascena modulated the oxidative stress and inflammation induced by CdCl2. The hepatic and cardiac tissue damage and histopathological alterations resulting from the CdCl2-induced oxidative stress were counteracted by the administration of R. damascena extracts. R. damascena enhanced antioxidant defence enzymes in male rats.

Project description:BackgroundThevetia peruviana (Pers.) K. Schum or Cascabela peruviana (L.) Lippold (commonly known as ayoyote, codo de fraile, lucky nut, or yellow oleander), native to Mexico and Central America, is a medicinal plant used traditionally to cure diseases like ulcers, scabies, hemorrhoids and dissolve tumors. The purpose of this study was to evaluate the cytotoxic, antiproliferative and apoptotic activity of methanolic extract of T. peruviana fruits on human cancer cell lines.MethodsThe cytotoxic activity of T. peruviana methanolic extract was carried out on human breast, colorectal, prostate and lung cancer cell lines and non-tumorigenic control cells (fibroblast and Vero), using the MTT assay. For proliferation and motility, clonogenic and wound-healing assays were performed. Morphological alterations were monitored by trypan blue exclusion, as well as DNA fragmentation and AO/EB double staining was performed to evaluate apoptosis. The extract was separated using flash chromatography, and the resulting fractions were evaluated on colorectal cancer cells for their cytotoxic activity. The active fractions were further analyzed through mass spectrometry.ResultsThe T. peruviana methanolic extract exhibited cytotoxic activity on four human cancer cell lines: prostate, breast, colorectal and lung, with values of IC50 1.91 ± 0.76, 5.78 ± 2.12, 6.30 ± 4.45 and 12.04 ± 3.43 μg/mL, respectively. The extract caused a significant reduction of cell motility and colony formation on all evaluated cancer cell lines. In addition, morphological examination displayed cell size reduction, membrane blebbing and detachment of cells, compared to non-treated cancer cell lines. The T. peruviana extract induced apoptotic cell death, which was confirmed by DNA fragmentation and AO/EB double staining. Fractions 4 and 5 showed the most effective cytotoxic activity and their MS analysis revealed the presence of the secondary metabolites: thevetiaflavone and cardiac glycosides.ConclusionT. peruviana extract has potential as natural anti-cancer product with critical effects in the proliferation, motility, and adhesion of human breast and colorectal cancer cells, and apoptosis induction in human prostate and lung cancer cell lines, with minimal effects on non-tumorigenic cell lines.
