In rats cisplatin induces hypocalcemia, bloating of the stomach, and ulceration ameliorated through calcium supplements. This study was undertaken to test the role of calcium on the gastrin mRNA production in vitro and in vivo. RIN B6 cells were cultured in medium with calcium (1.8, 3.6 and 7.2 mM) and the active form of vitamin D (calcijex). Cisplatin was added (10 μg/ml) for 12 hrs and cells were harvested for RNA from various treatment groups. Male Wistar rats were treated with cisplatin (9 mg/kg), before and after vitamin D (0.3 mg/100g/week). The rats were killed and stomach tissues excised on 1, 6, 10 and 15 days after cisplatin treatment. RNA from the stomach was analyzed using the northern blot technique. Gastrin mRNA was suppressed after cisplatin treatment both in vitro and in vivo. In vitro calcium but not vitamin D additions partially prevented the gastrin mRNA. In vivo, however, vitamin D and calcium were equally effective in preventing gastrin mRNA loss.
