Bottom Line: PCC displayed a strong suppressive effect on SNU-475 and SNU-423 cells with an IC50 value of 6.98 ± 0.11 μg/ml and 7.76 ± 0.45 μg/ml respectively, after 24 h of treatment.Activation of this pathway was further evidenced by significant activation of caspase 3/7 and 9.Cell cycle arrest in the G1 phase was confirmed by flow cytometry and up-regulation of glutathione reductase expression was quantified by qPCR.

ABSTRACT
The current study evaluates the cytotoxic mechanism of a novel piperazine derivate designated as PCC against human liver cancer cells. In this context, human liver cancer cell lines, SNU-475 and 243, human monocyte/macrophage cell line, CRL-9855, and human B lymphocyte cell line, CCL-156, were used to determine the IC50 of PCC using the standard MTT assay. PCC displayed a strong suppressive effect on SNU-475 and SNU-423 cells with an IC50 value of 6.98 ± 0.11 μg/ml and 7.76 ± 0.45 μg/ml respectively, after 24 h of treatment. Significant dipping in the mitochondrial membrane potential and elevation in the released of cytochrome c from the mitochondria indicated the induction of the intrinsic apoptosis pathway by PCC. Activation of this pathway was further evidenced by significant activation of caspase 3/7 and 9. PCC was also shown to activate the extrinsic pathways of apoptosis via activation of caspase-8 which is linked to the suppression of NF-ƙB translocation to the nucleus. Cell cycle arrest in the G1 phase was confirmed by flow cytometry and up-regulation of glutathione reductase expression was quantified by qPCR. This study suggests that PCC is a simultaneous inducer of intrinsic and extrinsic pathways of apoptosis in liver cancer cell lines.

Cytoskeletal rearrangement potential of PCC.Cells were treated with various concentrations of PCC for 24 h, followed by fixation and staining with Hoechst 33342 and phalloidin. Dose dependent increase of phalloidin intensity was observed in both SNU-423 and 475 cells. Bar charts show the average fluorescence intensity of phalloidin. All data were expressed as the means ± standard error of triplicate measurements. *P < 0.05 compared with the no-treatment group.

Mentions: SNU-475 and SNU-423 cells treated with PCC were examined for cytoskeletal and nuclear morphological alteration by phalloidin and Hoechst 33342 staining. F-actin was stained at the peripheral membrane evidencing the cell shrinkage (Fig. 4). In addition, nuclear fragmentation and condensation were indicated at the concentrations of 6.25 μg/ml of PCC in 24 h (Fig. 5). Additionally, apoptotic chromatin changes increased nuclear intensity suggesting induction of apoptosis by PCC in these cells.
