Figure 5. TOX4 regulates hepatic glucose metabolism independent of insulin receptor.
(A-B) Body weight (A) and 4-hr-fasting glucose (B) in 14- to 15-week-old male IR or TOX4 f/f (n=10), LIRKO (n=10) and liver-specific IR/TOX4 DKO (LIRTDKO, n=6) mice.
(C) PTT in 12- to 13-week-old TOX4/IR f/f (n=6) and LTIRDKO (n=9) mice.
(D) GTT, and (E) AUC in 14-week-old male IR f/f (n=6), LIRKO (n=9), LIRTDKO (n=6).
(F) 4-hr-fasting insulin of mice in (D).
(G) Liver gene expression as determined by QPCR.
(H) WB of selected liver proteins involved in glucose metabolism.
