Patterns of calcium channel (TRPV6) expression in rabbit gut epithelium
The present study was undertaken to explore the immunohistochemical localisation of TRPV6 calcium channels in rabbit gut epithelium that are actively involved in calcium absorption. To undertake the research, twelve apparently healthy adult female rabbits with a body weight between 1.0 to 1.5 kg were procured, acclimatised and divided into two groups: control and test. Both groups were kept on same feed along with exogenous calcium supplementation in test group animals only. The serum calcium level revealed that normally a high value of serum calcium is maintained in the rabbit as compared to other mammals, thus indicating that the homeostatic mechanism might be poorly developed. Immunohistochemistry and reverse transcription polymerase chain reaction analysis revealed that the caecum was the site of maximum calcium absorption in rabbit, followed by the duodenum and jejunum. The expression pattern of TRPV6 protein/mRNA was weaker in test group animals than in the control group, indicating that the channel was functional in low calcium concentration in the gut.
期刊介绍：
World Rabbit Science is the official journal of the World Rabbit Science Association (WRSA). One of the main objectives of the WRSA is to encourage communication and collaboration among individuals and organisations associated with rabbit production and rabbit science in general. Subject areas include breeding, genetics, production, management, environment, health, nutrition, physiology, reproduction, behaviour, welfare, immunology, molecular biology, metabolism, processing and products.
World Rabbit Science is the only international peer-reviewed journal included in the ISI Thomson list dedicated to publish original research in the field of rabbit science. Papers or reviews of the literature submitted to World Rabbit Science must not have been published previously in an international refereed scientific journal. Previous presentations at a scientific meeting, field day reports or similar documents can be published in World Rabbit Science, but they will be also subjected to the peer-review process.
World Rabbit Science will publish papers of international relevance including original research articles, descriptions of novel techniques, contemporaryreviews and meta-analyses. Short communications will only accepted in special cases where, in the Editor''s judgement, the contents are exceptionally exciting, novel or timely. Proceedings of rabbit scientific meetings and conference reports will be considered for special issues.
World Rabbit Science is published in English four times a year in a single volume. Authors may publish in World Rabbit Science regardless of the membership in the World Rabbit Science Association, even if joining the WRSA is encouraged. Views expressed in papers published in World Rabbit Science represent the opinion of the author(s) and do not necessarily reflect the official policy of the WRSA or the Editor-in-Chief.
