Tibetan chicken is one of those chicken breeds that could adapt to high altitude and low oxygen pressure environment; it owes to an integrative genetic mechanism for hypoxia adaptability compared to lowland chicken breeds. HIF-1α and HIF-2α are the central factors playing important roles in maintaining organisms’s oxygen homeostasis. In this study, the expression of HIF-1α and HIF-2α genes were investigated by Real Time-PCR in Tibetan chicken and Dwarf chicken embryo brain tissue under normoxia (21% oxygen concentration) and hypoxia (13% oxygen concentration). The results showed that Tibetan chicken always had lower mortality than Dwarf chicken during the incubation. We …
