AIMS To evaluate the changes of morphological and functional characteristics of the retinal pigment epithelium (RPE)-choroid perfusion culture during cultivation. METHODS PorcineRPE-choroid tissue was cultivated in a perfusion tissue culture system. After the indicated times, histology, immunolocalization of collagen IV and von Willebrand factor, RPE cell viability with calcein-AM, TUNEL assa...
Background and Objective: Apoptosis or programmed cell death is an important process for cellular homeostasis and it can be initiated by both physiologic and pathologic stimuli. Defects in the apoptosis process may lead to serious disease such as autoimmune diseases, cancer, tumors drug resistance, and the acquired immunodeficiency syndrome (AIDS). Various methods such as cytotoxicity assay, mo...
Background and Objective: Nowadays, extensive research is carried out on the effect of plant extracts on variety of disorders. In this study, the effect of hydroethanolic extract of Lavandula officinalis on proliferation of neural stem cells as well as its anti-apoptotic properties was assessed. Materials and Methods: Neural stem cells were isolated from hippocampus of neonatal rat brain. To...
The aim of this study was to examine the effect of crude bile on the human HepG2 and CCRF-CEM cell lines. Cells were exposed to different dilutions of bile. Antiproliferative effects were determined by the cytotoxic MTT assay. Cells undergoing apoptosis were identified by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Bile administration resulted in dose-dependent c...
Recently, indole-3-acetic acid (IAA) has been introduced as a new cancer therapeutic agent through oxidative decarboxylation by horseradish peroxidase (HRP). The purpose of this study was to determine the therapeutic feasibility of IAA/light combination against liver cancer. SK-HEP-1 cells were irradiated with UVB or visible light (518 nm) in the presence of IAA. Cell viability was measured usi...
BACKGROUND Although pyrimethamine (Tindurin) appears to be effective in the prevention and treatment of some infectious diseases, very little information exists on its unpredictable properties. We design this study to evaluate its anti-tumoral effect on a model of cell line. METHODS The cytotoxic influence of Pyrimethamine on prostate cell line was investigated using an in vitro colometric as...
Though piperazine derivative BK10007S was known to induce apoptosis in pancreatic cancer xenograft model as a T-type CaV3.1 a1G isoform calcium channel blocker, its underlying antitumor mechanism still remains unclear so far. Thus, in the present study, the antitumor mechanism of BK10007S was elucidated in hepatocellular carcinoma cells (HCCs). Herein, BK10007S showed significant cytotoxicity b...
BACKGROUND D3CLP (9-[(3-chloro)phenylamine]-2-[3-(diethylamine)propylamine]thiazolo[5,4-b]quinoline) is a potent cytotoxic thiazolo[5,4-b]quinoline synthetic derivative that induces apoptosis of leukemia cells, while it displays low toxicity towards non-tumoral cells. The aim of this study was to determine if D3CLP can enhance the cytotoxicity of other antineoplastic drugs. MATERIALS AND METH...
The reliability of eight distinct methods (Giemsa staining, trypan blue exclusion, acridine orange/ethidium bromide (AO/EB) double staining for fluorescence microscopy and flow cytometry, propidium iodide (PI) staining, annexin V assay, TUNEL assay and DNA ladder) for detection and quantification of cell death (apoptosis and necrosis) was evaluated and compared. Each of these methods detects di...
