HE Jian, et al. Neonatal vitamin A and LRAT is affected in marginal vitamin A deficiency rats[J]. Journal of Chongqing Medical University, 2010,35(7):974-977. DOI: 10.13406/j.cnki.cyxb.2010.07.025.
Objective:To investigate the effect of neonatal vitamin Aand LRAT in marginal vitamin Adeficiency(MVAD)rats during pregnancy.Methods:Sixteen adult female Wistar rats were randomly separated into control and MVAD groups (eight per group).Serum and livers from mothers and new borns were collected after the establishment of the above two animal models.The vitamin A level was analyzed by HPLC.RT-PCR and Western blot analysis were used to assay the transcriptional level and protein level of LRAT in neonatal liver.Results:The plasma and liver vitamin A level from maternal and neonatal was significantly lower in the MVAD compared to the control group (P<0.001)Meanwhile
LRAT mRNA and protein level were down-regulated (P<0.001).Conclusion:In the absence of dietary vitamin A from pregnancy
a normal level of plasma retinol alone was not enough to support body vitamin A storage.We can also conclude from our data that LRAT plays a crucial role in vitamin A storage.
