The aim of this study was to investigate the effect of lead (Pb) poisoning on nitric oxide (NO) content, inducible nitric oxide synthase (iNOS) activity, the messenger RNA (mRNA) levels of inflammatory factors (nuclear factor-kappa B (NF-κB), tumor necrosis factor-α (TNF-α), cyclooxygenase-2 (COX-2), prostaglandin E synthases (PTGEs), and iNOS), heat shock proteins (HSPs) (HSP27, HSP40, HSP60, HSP70, and HSP90), and the antagonistic effect of selenium (Se) on Pb in chicken livers. One hundred eighty 7-day-old male chickens were randomly divided into four groups and were fed commercial diet and drinking water, Na2SeO3-added commercial diet and drinking water, commercial diet and (CH3OO)2Pb-added drinking water, and Na2SeO3-added commercial diet and (CH3OO)2Pb-added drinking water, respectively, for 30, 60, and 90 days. Then, NO content, iNOS activity, and the mRNA levels of NF-κB, TNF-α, COX-2, PTGEs, iNOS, HSP27, HSP40, HSP60, HSP70, and HSP90 were examined in chicken livers. The results showed that Pb poisoning induced NO content, iNOS activity, and mRNA expression of inflammation factors and HSPs in chicken livers. In addition, Se alleviated Pb-induced increase of inflammation factor and HSP expression in chicken livers.

UI	MeSH Term	Description	Entries
D007249	Inflammation	A pathological process characterized by injury or destruction of tissues caused by a variety of cytologic and chemical reactions. It is usually manifested by typical signs of pain, heat, redness, swelling, and loss of function.	Innate Inflammatory Response,Inflammations,Inflammatory Response, Innate,Innate Inflammatory Responses
D007854	Lead	A soft, grayish metal with poisonous salts; atomic number 82, atomic weight 207.2, symbol Pb.
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
D008297	Male		Males
D009569	Nitric Oxide	A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.

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.
