Fisetin Induces Apoptosis of HSC3 Human Oral Cancer Cells Through Endoplasmic Reticulum Stress and Dysfunction of Mitochondria-mediated Signaling Pathways.

Background/aim: Oral cancer has been reported to be one of the major cancer-related diseases in human populations and the treatment of oral cancer is still unsatisfied. Fisetin, is a flavonoid from plants and has several biological activities such as antioxidant, anti-inflammatory and anticancer function, but its cytotoxicity in human oral cancer cells is unknown. In the present study, we investigated fisetin-induced cytotoxic effects on HSC3 human oral cancer cells in vitro.

Reduces Carbon Tetrachloride-induced Hepatotoxicity In Male Wister Rats.

Materials And Methods: We determined if Antrodia cinnamomea was hepatoprotective against carbon tetrachloride (CCl) toxicity in Wistar rats.

Chitosan promotes immune responses, ameliorating total mature white blood cell numbers, but increases glutamic oxaloacetic transaminase and glutamic pyruvic transaminase, and ameliorates lactate dehydrogenase levels in leukemia mice in vivo.

The aim of the present study was to investigate the effect of chitosan (a naturally derived polymer) on the immune responses and glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT) and lactate dehydrogenase (LDH) levels in WEHI‑3 cell‑generated leukemia mice. Mice were divided into control, WEHI‑3 control, acetic acid (vehicle)‑treated, and 5 and 20 mg/kg chitosan‑treated groups. Mice were subsequently weighed, blood was collected, and liver and spleen samples were isolated and weighed.

Boron Supply Enhances Aluminum Tolerance in Root Border Cells of Pea () by Interacting with Cell Wall Pectins.

Aluminum (Al) toxicity is the primary factor limiting crop growth in acidic soils. Boron (B) alleviates Al toxicity in plants, which is mainly considered to be due to the formation of Rhamnogalacturonan II-B (RGII-B) complexes, which helps to stabilize the cytoskeleton. It is unclear yet whether this is due to the increasing of net negative charges and/or further mechanisms.

Alkali-Soluble Pectin Is the Primary Target of Aluminum Immobilization in Root Border Cells of Pea (Pisum sativum).

We investigated the hypothesis that a discrepancy of Al binding in cell wall constituents determines Al mobility in root border cells (RBCs) of pea (Pisum sativum), which provides protection for RBCs and root apices under Al toxicity. Plants of pea (P. sativum L.

Chitosan promotes immune responses, ameliorates glutamic oxaloacetic transaminase and glutamic pyruvic transaminase, but enhances lactate dehydrogenase levels in normal mice .

Chitosan, a naturally derived polymer, has been shown to possess antimicrobial and anti-inflammatory properties; however, little is known about the effect of chitosan on the immune responses and glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT) and lactate dehydrogenase (LDH) activities in normal mice. The aim of the present study was to investigate whether chitosan has an effect on the immune responses and GOT, GPT and LDH activities in mice . BALB/c mice were divided into four groups.

Sulforaphane-induced apoptosis in human leukemia HL-60 cells through extrinsic and intrinsic signal pathways and altering associated genes expression assayed by cDNA microarray.

Sulforaphane (SFN), one of the isothiocyanates, is a biologically active compound extracted from cruciferous vegetables, and has been shown to induce cytotoxic effects on many human cancer cells including human leukemia cells. However, the exact molecular mechanism and altered gene expression associated with apoptosis is unclear. In this study, we investigated SFN-induced cytotoxic effects and whether or not they went through cell-cycle arrest and induction of apoptosis and further examined molecular mechanism and altered gene expression in human leukemia HL-60 cells.

Evaluation of Hirsutella sinensis mycelium for antifatigue effect.

The aim of this study was to investigate whether Hirsutella sinensis mycelium (HSM) has any antifatigue effect, using a forced swimming model in rats. Forty rats were randomly divided into five groups, each containing eight animals. The control group received 2 ml/kg body weight of distilled water and a positive control group was administered 1.

Deguelin inhibits the migration and invasion of U-2 OS human osteosarcoma cells via the inhibition of matrix metalloproteinase-2/-9 in vitro.

Osteosarcoma is the most common malignant primary bone tumor in children and young adults and lung metastasis is the main cause of death in those patients. Deguelin, a naturally occurring rotenoid, is known to be an Akt inhibitor and to exhibit cytotoxic effects, including antiproliferative and anticarcinogenic activities, in several cancers. In the present study, we determined if deguelin would inhibit migration and invasion in U-2 OS human osteosarcoma cells.

Phenethyl isothiocyanate inhibits in vivo growth of subcutaneous xenograft tumors of human malignant melanoma A375.S2 cells.

Numerous studies have shown that phenethyl isothiocyanate (PEITC) induces apoptosis of different types of human cancer cell lines, however, there are no reports showing that PEITC inhibits tumor growth in a xenograft model of melanoma in nude mice. We investigated effects of PEITC on the growth of xenografted A375.S2 cell tumors in nude BALB/c mice.

Evaluation of Hirsutella sinensis mycelium on food safety and anti-hepatoma activity in an animal model.
