Abstract
Flavonoids are metabolites widely distributed in plants and commonly present in foods, such as fruits and vegetables. Pectolinarin, which belongs to the flavone subclass, has attracted considerable attention due to its presence in many medicinal plants. It has turned out to be a good biological agent especially due to its antioxidant, anti-inflammatory, antidiabetic, and antitumor activities, evaluated both in vitro and in vivo. Its aglycone, the metabolite pectolinarigenin, is also known for a series of biological properties including anti-inflammatory and antidiabetic effects. In the first overview on the two metabolites here presented, their collection, isolation and the results of their biological evaluation are reported.

Exp Ther Med 2017; 14:5297-5304. [PMID: 29285056 PMCID: PMC5740812 DOI: 10.3892/etm.2017.5256] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2016] [Accepted: 03/24/2017] [Indexed: 11/08/2022] Open
Abstract
The aim of the present study was to investigate the protective effects of yak-activated protein on hematopoiesis and cytokine function in radiation-induced injury in mice. A total of 180 Kunming mice were randomly divided into three groups (A, B and C). Of these, 60 were randomly divided into a normal control group, a radiation model group, a positive control group and 3 yak-activated protein groups (high, medium and low dose groups; 10, 5 and 2.5 mg/kg, respectively). The other 120 mice were used for the subsequent experiments on days 7 and 14 following radiation. Yak-activated protein was administered orally to mice in the treatment groups and an equal volume of saline was administered orally to mice in the normal control and radiation model groups for 14 days. The positive control group received amifostine (150 mg/kg) via intraperitoneal injection. With the exception of the control group, the groups of mice received a 5 Gy quantity of X-radiation evenly over their whole body once. Changes in the peripheral hemogram, thymus and spleen indices, DNA content in the bone marrow, interleukin (IL)-2 and IL-6 levels, and the expression levels of B cell lymphoma 2 (Bcl-2) and Bcl-2-associated X protein (Bax) following irradiation were assessed. The low dose of yak-activated protein significantly increased Spleen indices in mice 14 days after irradiation and the high and middle dose of yak-activated protein significantly increased Thymus indices in mice 14 days after irradiation (P<0.05) compared with the control group. In addition, hemogram results increased gradually in the low-yak-activated protein dose group and were significantly higher 7 days after irradiation compared with the radiation model group (P<0.05). The DNA content in the bone marrow was markedly increased in the yak-activated protein groups, and increased significantly in the low dose group at 7 days post-irradiation compared with the radiation model group (P<0.05). The IL-2 content was significantly increased in the yak-activated protein groups (P<0.05). Furthermore, Bcl-2 expression was increased and Bax expression was decreased (P<0.05). These results suggest that yak-activated protein exerts protective effects against radiation-induced injury in mice. The optimal effects of yak-activated protein were observed in the medium dose group 14 days after irradiation.

Life Sci 2016; 148:173-82. [PMID: 26874034 DOI: 10.1016/j.lfs.2016.02.035] [Citation(s) in RCA: 38] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2015] [Revised: 01/21/2016] [Accepted: 02/09/2016] [Indexed: 01/07/2023]
Abstract
AIMS We investigated the neuroprotective effects and action mechanism of three major compounds [daucosterol (Dau), pectolinarin (Pec), and astragalin (Ast)] isolated from edible plants against H2O2-induced cell death of human brain neuroblastoma SK-N-SH cells. MAIN METHODS Cytotoxicity was determined by MTT and lactate dehydrogenase (LDH) assays. Apoptotic cell death was monitored by annexin V-FITC/PI double staining and by TUNEL assay. The formation of reactive oxygen species (ROS), expression of antioxidant enzymes and phosphorylation of mitogen-activated protein kinase (MAPK) were determined by 2,7-dichlorofluorescein diacetate (DCF-DA) assay, RT-PCR, and western blotting, respectively. KEY FINDINGS The ethyl acetate fractions from Cirsium setidens (CSEA) and Aster scaber (ASEA) showed neuroprotective effects in SK-N-SH cells. The phytochemicals were isolated from CSEA and ASEA and identified by spectral analyses, as β-sitosterol, Dau, Pec, Ast, or isoquercitrin. Pretreatment with Dau, Pec, or Ast showed protective effects against H2O2-induced cell death and inhibited ROS generation by oxidative stress. HO-1 mRNA and protein levels were increased by the presence of H2O2 and were further elevated by pretreatment with Dau and Ast. Dau pretreatment resulted in further increases of H2O2-induced enhancement in levels of CAT and SOD2. Pretreatment with Dau, Pec, and Ast inhibited phosphorylation of MAPK, such as extracellular protein regulated protein kinase, p38, and c-Jun N-terminal kinase by H2O2. SIGNIFICANCE Dau exerts its neuroprotective effects by down regulation of MAPK pathways and upregulation of the HO-1, CAT and SOD2 antioxidant genes and is associated with reduced oxidative stress in SK-N-SH cells.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2015; 12:8332-47. [PMID: 26193298 PMCID: PMC4515725 DOI: 10.3390/ijerph120708332] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/15/2015] [Revised: 06/29/2015] [Accepted: 07/02/2015] [Indexed: 01/09/2023]
Abstract
The protective effect of Lycium ruthenicum Murr. against radiation injury was examined in mice. Kunming mice were randomly divided into a control group, model group, positive drug group and L. ruthenicum high dose (8 g/kg), L. ruthenicum middle dose (4 g/kg), L. ruthenicum low dose (2 g/kg) treatment groups, for which doses were administered the third day, seventh day and 14th day after irradiation. L. ruthenicum extract was administered orally to the mice in the three treatment groups and normal saline was administered orally to the mice in the control group and model group for 14 days. The positive group was treated with amifostine (WR-2721) at 30 min before irradiation. Except for the control group, the groups of mice received a 5 Gy quantity of X-radiation evenly over their whole body at one time. Body weight, hemogram, thymus and spleen index, DNA, caspase-3, caspase-6, and P53 contents were observed at the third day, seventh day, and 14th day after irradiation. L. ruthenicum could significantly increase the total red blood cell count, hemoglobin count and DNA contents (p < 0.05). The spleen index recovered significantly by the third day and 14th day after irradiation (p < 0.05). L. ruthenicum low dose group showed a significant reduction in caspase-3 and caspase-6 of serum in mice at the third day, seventh day, and 14th day after irradiation and L. ruthenicum middle dose group experienced a reduction in caspase-6 of serum in mice by the seventh day after irradiation. L. ruthenicum could decrease the expression of P53. The results showed that L. ruthenicum had protective effects against radiation injury in mice.
