Expression of phosphorylated inositol-requiring enzyme 1 (P-IRE1), a marker of endoplasmic reticulum stress, was significantly greater in the CLO group than the TIC group (P = 0.038); it also showed a trend toward greater expression in the CLO group than in the CTL group (P = 0.090), although there was no significant difference between the CTL and TIC groups (N = 7 for CLO; N = 6 for TIC and CTL, Fig 3F ).
