Cognitive Protective Mechanism of Crocin Pretreatment in Rat Submitted to Acute High-Altitude Hypoxia Exposure
Figure 4
Crocin pretreatment improves the expression of mitochondrial biosynthesis-related factors in rat’s hippocampal cells under acute high-altitude hypoxia. Ctr: control group, with saline. AHH: rats exposed under hypoxia for 3 days at 4200 m. LHG, MHG, HHG: rats exposed under hypoxia for 3 days at 4200 m after pretreatment by 25 mg/kg/d, 50 mg/kg/d, and 100 mg/kg/d of crocin). (a, b) Western blot detection of NRF1 and TFAM protein expression in the hippocampus (). (c) NRF1 and TFAM mRNA expression by qRT-PCR in the hippocampus (). # versus Ctr, versus AHH, ■ versus Ctr, △ versus HLG, and ▲ versus HMG.
