Ted with 20, 40 and 80 POA, respectively (Fig. 6B). MDA content. MDA can be a well-studied intermediate of oxidative strain (24). HK-2 cells treated with 20, 40 and 80 POA exhibited a substantial improve in MDA levels (Fig. 6C). MDA levels in manage cells had been 0.40 nmol/mg of total protein, and these levels were enhanced to 0.72 (P0.01 vs. handle), 1.22 (P0.001 vs. handle) and 1.65 nmol/mg (P0.001 vs. handle) with 20, 40 and 80 POA, respectively (Fig. 6C).SHI et al: TOXICITY OF OXALICUMONE A IN RENAL EPITHELIAL CELLSFigure six. Impact of POA around the antioxidant status of HK-2 cells. HK-2 cells were treated with 0, 20, 40 or 80 POA for 24 h plus the cell lysates (for endogenous molecules assessment) or the culture medium (for assessment of molecules released extracellularly) were tested by ELISA or specific dye kits.

Information are presented as the imply normal deviation of 3 independent experiments. P0.05, P0.01 and P0.001 vs. control. POA, oxalicumone A; GSH, glutathione; SOD, superoxide dismutase; MDA, malondialdehyde; NO, nitric oxide; NAG, N-acetyl–D-Glucosaminidase; LDH, lactate dehydrogenase.Impact of POA on expression of apoptotic markers. Bcl-2 is a Bcl-2 loved ones anti-apoptotic protein, which aids cells to stop apoptosis. Bax can be a Bcl-2 loved ones pro-apoptotic protein, that translocates from the internal for the outer mitochondrial membrane, inducing the release of pro-apoptotic factors, and resulting in apoptosis. The expression levels of Fas, Bax and Bcl-2 have been analyzed by western blot in HK-2 cells treated with 0, 20 or 40 POA for 24 h (Fig. 9). POA treatment substantially increased protein expression levels of Fas and Bax compared with control (Fig. 9). By contrast, the expression of Bcl-2 was drastically decreased with POA treatment, compared with handle (Fig. 9). These outcomes indicated that POA remedy resulted in an upregulation from the pro-apoptotic proteins Fas and Bax plus a downregulation of the anti-apoptotic protein Bcl-2. Discussion Prior research have demonstrated that POA exhibits considerable cytotoxicity against many carcinoma cell lines with IC5010 (three,five) nevertheless, the pharmacological mechanism remains unknown. The present study was made to assess for the initial time the toxic impact of POA on proximal tubular cells. Employing a cell viability assay, it was demonstrated that POA treatment inhibited proliferation of HK-2 cells inside a dose-dependent manner (Fig. two), suggesting that POA treatment can induce cytotoxicity in human renal epithelial cells.Figure 7.
