Piceatannol induced apoptosis through up-regulation of microRNA-181a in melanoma cells Biol. Res.
Du,Maotao; Zhang,Zhong; Gao,Tao.
Abstract Background Melanoma took top position among the lethal cancers and, despite there have been some great attempts made to increase the natural life of patients with metastatic disease, long-lasting and complete remissions are few. Piceatannol, owns the similar function as resveratrol, has been defined as an anti-cancer agent playing important role in inhibition of proliferation, migration and metastasis in various cancer. Thus, we aim to investigate the anti-cancer effect and mechanisms of piceatannol in melanoma cells. Methods Melanoma cell lines WM266-4 and A2058 were treated either with or without piceatannol. Cell viability and cell apoptosis were assessed by using MTT and Annexin V/PI assay, respectively. Cells were transfected with specific...

Morphological alterations and G0/G1 cell cycle arrest induced by curcumin in human SK-MEL-37 melanoma cells BABT
Carneiro,Marcella Lemos Brettas; Porfírio,Elaine Paulucio; Otake,Andréia Hanada; Chammas,Roger; Báo,Sônia Nair; Guillo,Lidia Andreu.
The aim of this work was to study the effect of curcumin on cell cycle in the human SK-MEL-37 melanoma cell line. In addition, morphological and structural analyses were also performed. Flow cytometric analysis showed a G0/G1 arrest at 5 µM after 24 h exposure and a concentration-dependent increase in the proportion of sub-G0 hypodiploid cells. Typical apoptotic events were also observed by the fluorescence microscopy, transmission and scanning electronic microscopy. Loss of mitochondrial membrane potential was not detected. Results suggested that curcumin could arrest human melanoma cells at G0/G1 phase and induce a mitochondrial-independent apoptotic pathway.
