Fig. 5: Functional assays of the IGSF22S132F genotype.

A Western-blotting analysis of the HEK293T cell lysates transfected with the plasmid of WT, S132F, and empty vector. B The mRNA expression levels of the WT and IGSF22S132F measured by RT-qPCR. C Effect of hypoxic stimulus on the cell viability of HEK293T cells. D Effect of hypoxic stimulus on the apoptosis of HEK293T cells. E Gene expression of the hypoxia-related genes, including AKT1, ABCG2, and VEGFA in transfected HEK293T cells.
