Abstract:

Background: Vitamin A is very important for development of multiple organ systems in the body. Retinoid X receptor γ (RXRγ) is one of the nuclear receptors through which vitamin A helps in various biological processes. We experimented to show expression of RXRγ through immunohistochemistry in early neonatal rat brains. Methodology: A series of experiments were carried out to optimize the immunohistochemistry protocols for RXRγ in early neonatal rat brains. Immunohistochemistry protocol for RXRγ was modified from the protocol available for adult rat brain in literature. We have done RXRγ immunohistochemistry for rat brains at the ages of 3, 10, 18 and 60 days. We have compared the immunostaining with the nissle-stained sections of the same brains to show the staining pattern of RXRγ immunohistochemistry. Results: Our experiments revealed characteristics of immunostaining for RXRγ. It was shown that RXRγ protein was present in the cytoplasm as well as nuclei. The cellular processes also took the immunostain. Additionally, our immunohistochemistry results clearly showed that more cells are visible through Nissle staining as compared to RXRγ immunohistochemistry. Conclusion: We could present expression of RXRγ in early neonatal and adult rat brains through immunohistochemistry. We have documented the sensitivity of RXRγ to various commonly practiced methodological components for immunohistochemistry. Our study has not only developed a successful immunohistochemistry protocol for RXRγ in early neonatal rat brains but it may help future researchers to tackle sensitive proteins for immunohistochemistry.
