Calcitriol protects against the dopamine- and serotonin-depleting effects of neurotoxic doses of methamphetamine

Abstract

Abstract: Repeated methamphetamine (METH) administration to animals can result in long‐lasting decreases in brain dopamine (DA) and serotonin (5‐HT) content. Calcitriol, the active metabolite of vitamin D, has potent effects on brain cells, both in vitro and in vivo, including the ability to upregulate trophic factors and protect against various lesions. The present experiments were designed to examine the ability of calcitriol to protect against METH‐induced reductions in striatal and nucleus accumbens levels of DA and 5‐HT. Male Fischer‐344 rats were administered vehicle or calcitriol (1μg/kg, s.c.) once a day for eight consecutive days. After the seventh day of treatment the animals were given METH (5 mg/kg, s.c.) or saline four times in 1 day at 2‐h intervals. Seven days later the striata and accumbens were harvested from the animals for high‐performance liquid chromatography (HPLC) analysis of monoamines and metabolites. In animals treated with vehicle and METH, there were significant reductions in DA, 5‐HT, and their metabolites in both the striatum and accumbens. In animals treated with calcitriol and METH, the magnitude of the METH‐induced reductions in DA, 5‐HT, and metabolites was substantially and significantly attenuated. The calcitriol treatments did not reduce the hyperthermia associated with multiple injections of METH, indicating that the neuroprotective effects of calcitriol are not due to the prevention of increases in body temperature. These results suggest that calcitriol can provide significant protection against the DA‐ and 5‐HT‐depleting effects of neurotoxic doses of METH.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Response to vitamin D supplement could vary between children with ASD and children with developmental delay because vitamin D may affect brain chemistry.

    “The brain chemistry of children with ASD may differ from that of children with developmental delay [142], and as such the response to vitamin D supplement—that may affect brain chemistry [143]—could vary.”

  • Pre-treatment with calcitriol protects rats' striatum and accumbens from methamphetamine-induced reduction in dopamine and serotonin.

    “Pre-treatment with calcitriol has been shown to protect rats’ striatum and accumbens from methamphetamine-induced reduction in dopamine and serotonin [143].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
