Description |
Cisplatin is a antineoplastic chemotherapy drug which works by cross-linking with DNA and causing DNA damage in cancer cells.

DNA Alkylator/Crosslinker[1]

In Vitro |
Cisplatin (CDDP) causes apoptosis of HeLa cells in a dose-dependent manner, with a concentration of 30 μM Cisplatin resulting in death of greater than 90% of the cell population by 24 h of treatment. The kinetics of Cisplatin-induced apoptosis are examined using a 30 μM concentration. Cisplatin Activates the MEK/ERK Signaling Pathway, 20 and 30 μM Cisplatin, both of which results in significant apoptosis, leads to strong activation of ERK[1]. Cisplatin (50 μM) produces time-dependent apoptosis in renal proximal tubular cell (RPTCs), causing cell shrinkage, a 50-fold increase in caspase 3 activity, a 4-fold increase in phosphatidylserine externalization, and 5- and 15-fold increases in chromatin condensation and DNA hypoploidy, respectively[2].

In Vivo |
In melanoma-bearing mice, Cisplatin (4 mg/kg B.W.) reduces the size and weight of the solid tumors, and HemoHIM supplementation with Cisplatin enhances the decrease of both the tumor size and weight[3]. Cisplatin administration results in significant increases in the kidney weight as a percentage of the total body weight, urine volume, serum creatinine, and blood urea nitrogenby about 132, 315, 797, and 556% in comparison with the control rats, respectively[4].

Cell Assay |
HeLa and A549 cells are maintained in Dulbecco's modified Eagle's medium supplemented with 10% fetal bovine serum, 100 units of Penicillin, and 100 μg of Streptomycin/mL. They are cultured at 37°C in a humidified chamber containing 5% CO2. For the induction of apoptosis, cells are plated in 60-mm dishes 1 day prior to Cisplatin (0-30 μM) treatment[1].

Animal Admin |
Mice[3] Mice are divided randomly into three groups (Control, Cisplatin and Cisplatin+HemoHIM), and each group consists of twenty mice. B16F0 melanoma (5×105 cells/mouse) is inoculated into subcutaneous femoral left region of mice at 3 days before an initial injection of Cisplatin. Cisplatin is injected intraperitoneally at 4 mg/kg body weight (B.W.) on day 0, 7 and 14 (total three injections). Experimental group is intubated with HemoHIM at a final concentration of 100 mg/kgB.W. by everyday from day -1 to day 16, while the control group received only water. On day 17 after initial injection of Cisplatin, all mice of each group are experimented, respectively, to evaluate tumor weight or tumor size. The tumor size is calculated as follows: tumor size=ab2/2, where a and b are the larger and smaller diameters, respectively. Rats[4] Male Sprague-Dawley rats weighing 200 to 250 g are divided at random into 4 groups of 4 or 5 animals each. The first group (control) received a vehicle (5% carboxymethyl cellulose sodium solution (CMC-Na), 5 mL/kg body wt., p.o.) used for Capsaicin (Cap). The second group received Cap (10 mg/kg/d, p.o.) in 5% CMC-Na (5 mL/kg), and the third received 5% CMC-Na for 6 consecutive days injected with Cisplatin (5 mg/kg in physiological saline solution, i.p.). The fourth group received Cap (10 mg/kg/d, p.o.) in 5% CMC-Na for 6 consecutive days after Cisplatin injection (5 mg/kg, i.p.). For all groups, Cap or vehicle is given twice daily. The selected Cap concentration and the dose administration schedule without inducing any rat intestinal damage are chosen using data from our preliminary experiments.
