Fig. 1From: Tunicamycin promotes metastasis through upregulating endoplasmic reticulum stress induced GRP78 expression in thyroid carcinomaGRP78 expression is increased in thyroid carcinoma. a IHC was performed to compare the expression of GRP78 in TC tissues with peri-tumor tissues. b The scores of IHC showed increased levels of GRP78 in normal tissues when compared with peri-tumor tissues. ∗∗p < 0.01. c The scores of IHC showed the levels of GRP78 in stage I-II as compared with stage III-IVBack to article page
