Abstract

Isoflavones constitute a large series of compounds found in many plants. They make up an important part of the diet and have a broad spectrum of biological activities such as cytotoxic and antitumor effects. Lupiwighteone (Lup) is an isoflavone-type compound. It is distributed widely in wild-growing plants such as Glycyrrhiza glabra, Lupinus, and Lotus pedunculatus. On the basis of existing research, Lup shows antioxidant and antimicrobial effects, but its antitumor activity has not been reported as yet. This study aimed to examine the antitumor activity of Lup, explore its antitumor mechanism in a human prostate carcinoma cell line (DU-145), and evaluate its antiangiogenetic activity in the human umbilical vein endothelial cell line (HUVEC). The results showed that Lup could inhibit the growth of DU-145 and HUVEC cells in a concentration-dependent and time-dependent manner by a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay. Flow cytometry analysis indicated that Lup could induce cell cycle arrest, cells apoptosis, mitochondrial membrane potential loss, and an increase in intracellular reactive oxygen species of DU-145 cells. Upregulation of Bax, cytochrome c, caspase-3, and PARP-1 protein expressions and ...Continue Reading

AKT Pathway

This feed focuses on the AKT serine/threonine kinase, which is an important signaling pathway involved in processes such as glucose metabolism and cell survival.

Angiogenesis Inhibitors to Treat Cancer

Cancer treatments including angiogenesis inhibitors prevent tumor cells from receiving nutrients and oxygen. Here is the latest research on angiogenesis inhibitors for the treatment of cancer.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.
