Distribution and Expression Pattern of Neuroglobin in The Bactrain Camel Brain

Neuroglobin (Ngb) is a member of the vertebrate globin family involved in cellular oxygen homeostasis and reactive oxygen/nitrogen scavenging. It is an intracellular haemoprotein expressed in the central and peripheral nervous system, cerebrospinal fluid, retina and endocrine tissues. The study examines the distribution of Ngb in the brain of Bactrian Camel and compared the results with published results of yak, and cattle. The immunohistochemical staining method was used to observe the distribution of Ngb in the brain of healthy adult Bactrian camels. Ngb is significantly expressed in all tissues of the telencephalon except the hypothalamus. The cerebellar cortex, hippocampus, amygdala, cerebellum, and corpus callosum recorded the highest expression and each plays an important role in the Bactrian camel. In the Yak and cattle brain, Ngb were scattered in the cerebral cortex and were significantly higher than that in the cerebellar cortex, hippocampus, medulla oblongata, striatum, and olfactory bulb.
