Objective: This study evaluated the antiproliferative and pro-apoptotic effects of coenzyme Q0 (CoQ0) in human chronic myeloid leukemia K562 cell line. Material Method: The cytotoxic effect CoQ0 on line, was determined by MTT test. activity caspase-3, expression proteins involved apoptosis, MAPK AKT signaling pathways were with enzymatic assay western blot analysis, respectively. Result Discuss...

conclusions the proliferation and invasion of human bladder cancer cells can be inhibited by rnai-targeting skp2. as a result, skp2 may be a potential target for gene therapy in cases of human bladder cancer. materials and methods the expression of the skp2 gene was knocked down by rna interference (rnai) in t24 cells. the transcription level of skp2 was detected by reverse transcription-quanti...

BACKGROUND Sanguinarine is a benzophenanthridine alkaloid derived from the root of Sanguinaria canadensis, which induces apoptosis in human cancer cells, but the underlying action mechanisms are not completely understood. We investigated the mechanisms of sanguinarine on the induction of apoptosis using U937 leukemia cells. METHODS Cytotoxicity was evaluated by MTT assay. Apoptosis was detect...

PURPOSE Benzyl alcohol (BA) is the preservative in triamcinolone acetonide (TA) suspensions, which are used in treating vitreoretinal diseases and during surgery. This paper investigates the molecular mechanisms and signaling pathways underlying BA toxicity in human retinal pigment epithelial (RPE) cells. METHODS Cultured human RPE cells from the ARPE-19 cell line were exposed to culture medi...

Luteolin is a flavonoid and considered to be important for anti-cancer activity against many cancer cells. However its mechanism of action is poorly understood as well as systematics study on its action on different cancer cell line is still obscure. In this study we checked luteolin activity against number of cell line and according to our screen mouse liver cancer cells (HepG2) is found to be...

Dihydroartemisinin (DHA), a front-line antimalarial herbal compound, has been shown to possess promising anticancer activity with low toxicity. We have previously reported that DHA induced caspase-3-dependent apoptosis in human lung adenocarcinoma cells. However, the cellular target and molecular mechanism of DHA-induced apoptosis is still poorly defined. We use confocal fluorescence microscopy...

Apoptosis, programmed cell death, is a process involved in the development and maintenance of cell homeostasis in multicellular organisms. It is typically accompanied by the activation of a class of cysteine proteases called caspases. Apoptotic caspases are classified into the initiator caspases and the executioner caspases, according to the stage of their action in apoptotic processes. Althoug...

B-acute lymphoblastic leukemia (B-ALL) is the frequent pediatric malignity. Chemotherapy is the most practical approaches to deal with such malignancies. Microtubule-targeted agents are one of the most strategic drugs which formerly use in chemotherapy.Although,colchicine-binding anti-tubulin agents exhibited promising effects in clinical trials, their exact mechanism of action is not fully und...

Inhibitors and activators of protein-protein interactions are valuable as biological probes and medicinal agents but are often difficult to identify. Herein we describe a high-throughput assay, based upon photonic crystal (PC) biosensors, for the identification of modulators of protein-protein interactions. Through the use of a d-biotin-tris-NTA (BTN) hybrid compound, any His6-tagged protein ca...
