This study aims to investigate the inhibitory effects of oridonin nanosuspension on human prostatic carcinoma PC-3 cell line in vitro. The PC-3 cells were incubated with increasing concentrations of oridonin solution and nanosuspensions for 12 hours, 24 hours, and 36 hours. MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay was performed to measure cellular viability and i...
We describe here a technical improvement of an established colorimetric method used to detect and measure the occurrence of apoptosis in mammalian cells during in vitro cell culture. This assay uses an anionic halogenated fluorescein dye that is taken up by apoptotic cells at the stage of phosphatidylserine externalization. We demonstrate that apoptotic cells stained with this dye can be detect...
Chrysophanol is an anthraquinone compound, which exhibits anticancer effects on certain types of cancer cells. However, the effects of chrysophanol on human breast cancer remain to be elucidated. The aim of the present study was to clarify the role of chrysophanol on breast cancer cell lines MCF‑7 and MDA‑MB‑231, and to identify the signal transduction pathways regulated by chrysophanol. MTT as...
The purpose of the present study is to investigate the cytotoxicity/apoptotic effect of 2-chloro-2′-deoxyadenosine, cladribine, (2-CdA) in the human breast cancer cell line, MDA-MB468 (estrogen receptor negative, ER−). MTT [3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H tetrazolium bromide] assay, annexin V-Fluorescein/PI and Hoechst 33258 staining were used to detect cytotoxicity and cell apopto...
Background: Regarding the strong differentiation and anti-leukemic activity of Dendrostellera lessertii extract, an active agent with similar capabilities was isolated from the crude extract of the plant leaves. The aim of this study was to determine whether the anti-proliferative effect observed for this compound, is differentiation-dependent among the drug-treated cells, using U937 cells. Me...
PURPOSE The pharmacological activities, notably the anticancer properties, of bioactive constituents fromfresh American ginseng berry have not yet been well studied. In this study, we investigated the antiproliferative effects of fresh American ginseng berry extract (AGBE) and its representative triterpenoid glycosides using the human colorectal cancer cell line SW480. MATERIALS AND METHODS U...
Human prostatic stromal myofibroblasts have been shown to be related to lower urinary tract symptoms (LUTS) in aging men. Devazepide, also known as a nonpeptide antagonist of CCK receptor, has been found to inhibit the proliferation in tumor cells. Here, we aim to investigate the effects of Devazepide on growth and contraction ability in human prostatic stromal WPMY-1 myofibroblasts. Human pros...
OBJECTIVE Endothelial microparticles (EMP) are released from activated or apoptotic cells, but their effect on target cells and the exact way of incorporation are largely unknown. We sought to determine the uptake mechanism and the biological effect of EMP on endothelial and endothelial-regenerating cells. METHODS AND RESULTS EMP were generated from starved endothelial cells and isolated by u...
OBJECTIVES More than half of head and neck squamous cell carcinoma (HNSCC) patients are initially treated with curative intent, but will relapse over the course of their disease and have poor prognosis with a median survival of approximately 6months. Novel therapeutic approaches are in desperate need for this patient population. The anti-apoptotic BCL-2 family proteins such as BCL-2, BCL-XL, an...
Objective: To determine the effect of convallatoxin on K562 cell proliferation and apoptosis. Methods: CCK-8 assay was used to detect proliferation; PI staining, JC-1 Annexin V-FITC/PI double staining were analyze cycle, mitochondrial membrane potential, apoptosis; Western blotting cleaved caspase-9, caspase-3, Bcl-2, Bax, E2F1 expression Akt phosphorylation. Subsequently, AutoDock software int...
