Genome-Wide Transcriptional Analysis Reveals the Protection against Hypoxia-Induced Oxidative Injury in the Intestine of Tibetans via the Inhibition of GRB2/EGFR/PTPN11 Pathways

Figure 2

Electroscopic studies of the digestive tract in the IMB of Tibetans and Han Chinese at high altitude. (a) Intestinal villi are usually reduced and appear irregular in the IMB of Tibetans. (b) Intestinal villi are usually rich in the Han Chinese. (c) Glandular epithelium is destroyed in the IMB of Tibetans. (d) Glandular epithelium is in a fine situation in Han Chinese.
