A series of experiments were conducted to study the basal amounts of vitamin D-1α-hydroxylase and vitamin D-24-hydroxylase mRNA amounts in different organs and the effect of immune stimulation on 1α- and 24-hydroxylase mRNA amounts in chickens. At day of hatch, kidneys had an approximately 66-fold higher amount of 1α-hydroxylase and 550-fold higher amount of 24-hydroxylase mRNA, thigh and breast muscles had an approximately 20-fold higher amount of 1α-hydroxylase mRNA, and the thymus had an approximately 41-fold higher amount of 24-hydroxylase mRNA than the liver. An in vivo LPS injection did not alter the amount of 1α-hydroxylase mRNA in the breast muscle (P=0.60) or in the kidneys (P=0.39). An in vivo LPS injection decreased (P=0.01) the amount of 24-hydroxylase mRNA in the breast muscle at 3 d post-LPS injection. An in vivo LPS injection increased (P=0.01) the amount of 24-hydroxylase mRNA in the kidneys at 2, 3, and 6 d post-LPS injection. An in vitro stimulation altered amounts of 1α- (P=0.01) and 24-hydroxylase (P=0.04) mRNA in CD4+ cells. In conclusion, the distribution of 1α- and 24-hydroxylase mRNA amounts was similar to mammals, and an immune stimulation altered the amounts of 1α- and 24-hydroxylase mRNA in chickens.

UI	MeSH Term	Description	Entries
D007668	Kidney	Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.	Kidneys
D008070	Lipopolysaccharides	Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed)	Lipopolysaccharide,Lipoglycans
D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
D008221	Lymphoid Tissue	Specialized tissues that are components of the lymphatic system. They provide fixed locations within the body where a variety of LYMPHOCYTES can form, mature and multiply. The lymphoid tissues are connected by a network of LYMPHATIC VESSELS.	Lymphatic Tissue,Lymphatic Tissues,Lymphoid Tissues,Tissue, Lymphatic,Tissue, Lymphoid,Tissues, Lymphatic,Tissues, Lymphoid
D011201	Poultry Diseases	Diseases of birds which are raised as a source of meat or eggs for human consumption and are usually found in barnyards, hatcheries, etc. The concept is differentiated from BIRD DISEASES which is for diseases of birds not considered poultry and usually found in zoos, parks, and the wild.

D002478	Cells, Cultured	Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.	Cultured Cells,Cell, Cultured,Cultured Cell
D002645	Chickens	Common name for the species Gallus gallus, the domestic fowl, in the family Phasianidae, order GALLIFORMES. It is descended from the red jungle fowl of SOUTHEAST ASIA.	Gallus gallus,Gallus domesticus,Gallus gallus domesticus,Chicken
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D012333	RNA, Messenger	RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
