PJNK (46, 55 kDa), PERK (44, 42 kDa), and Pp38 (43 kDa) specific bands have been detected by Western blot. (A) Immunoblot represents the observations from a single single experiment repeated three instances. The integrated optical densities of (B) PJNK, (C) PERK1/2, (D) and pp38 proteins were analyzed soon after normalization with all the total protein in every single lane.

In actual fact, the synergistic/additive impact of cisplatin plus other drugs has been demonstrated in nasopharyngeal cancer (NPC) cell lines (NPCTWand NPCTW04), human HNSCC cell line SCC25, and human epidermoid carcinoma A431 cells.34,35 It has also been shown that a mixture of diverse agents could induce extra antitumor efficiency; 36 therefore, our findings are constant with those investigations.OncoTargets and Therapy 2013:submit your manuscript | www.dovepress.comDovepressChen et alDovepressADMSO Cordycepin ( ) Cisplatin ( ) PJNK (46, 55 kD) JNK PERK (44, 42 kD) ERK Pp38 (43 kD) p38 actin (43 kD) 6 hours 100 one hundred one hundred 300 600 300 600 12 hours one hundred one hundred 300 600 300 100 600 24 hours one hundred one hundred 100 300 600 300 600 36 hours one hundred 100 300 600 300 100BC PERK/total ERK 5PJNK/total JNK 0 6 hours 12 hours 24 hours 36 hours0 6 hours 12 hours 24 hours 36 hoursTime D10 eight six 4 2 0 six hours 12 hours 24 hours 36 hoursTimePp38/total p TimeFigure 10 Effects of cordycepin and/or cisplatin around the protein expression of MAPK pathway in FaDu cells. Notes: Cells (4.five 105 cells/well for FaDu) were treated with plain medium, medium with DMSO (0.five ), medium with 100 cordycepin, medium with 300 cisplatin, medium with 600 cisplatin, medium with one hundred cordycepin plus 300 cisplatin, and medium with one hundred cordycepin plus 600 cisplatin for 6 hours, 12 hours, 24 hours, and 36 hours, respectively.

We further investigated irrespective of whether the caspase8 (extrinsic) and/or caspase9 (intrinsic) pathways would beactivated. Results showed that each extrinsic and intrinsic caspase pathways have been activated by the cordycepin plus cisplatin cotreatment. Lots of studies have shown the synergisti.
