Objective To explore the effects of deoxynivalenol (DON) on apoptosis of human gastric carcinoma cell line SNU in vitro. Methods SNU cells were treated with DON at different concentrations (50, 100, 1000, 2000 μg/L) for 12 hours, and then cells were harvested for cell apoptosis by flow cytometric (FCM) DNA analysis and the expression of Bax, Bcl-2 and Caspase-3 at protein level with FCM and Western blotting. Results FCM results showed that the apoptosis rates of SNU cells in DON treatment groups were all higher than that in control, especially in DON 1000 μg/L and 2000 μg/L groups (P<0.05). In the concentration range from 50 to 2000 μg/L, a significant concentration-depended response correlation could be found between apoptosis rate and DON concentration (r =0.940, P <0.01). FCM and Western blotting showed Bax and Caspase-3 expression in often SNU cells DON treatment for 12 hours were up-regulated while that of Bcl-2 was down-regulated. Conclusion DON can induce apoptosis of SNU cells in vitro in dose-dependent manner, and possible mechanisms of apoptosis induction effects may be up-regulation of the expression of Bax and down-regulation of that of Bcl-2 and activation of the key enzyme of apoptosis Caspase-3.

Purpose To study the expression of HIF-1αand Glut-1 in the molecular subtypes of breast carcinoma and their correlation with basal-like breast carcinoma. Methods 803 cases of invasive breast carcinoma from our database were identified. The clinicopath-ologic findings and the biologic markers including estrogen receptor ( ER) , progesterone receptor ( PR) , and human epidermal growth factor receptor-2 (HER-2) status were reviewed. Immunohistochemical MaxVision stains for cytokeratin 5/6 (CK5/6) and epidermal growth factor receptor ( EGFR) were performed. All breast carcinomas were subclassified into Luminal A, Lumincal B, HER-2 over-expression, normal-like, and basal-like subtypes according to Nielsen criteria. Immunohistochemical stain was also used to detect the expression of HIF-1αand Glut-1. Results Positive expression rates of HIF-1αprotein in basal-like, HER-2 over-expression, normal-like, Luminal A and Luminal B substypes were 77. 89% (74/95), 56. 06% (37/66), 55. 76% (92/165), 31. 97% (141/441), 25. 00% (9/36), respectively. The positive expression rates of Glut-1 protein were 80. 00% (76/95), 57. 58% (38/66), 58. 18%(96/165), 34. 01% (150/441), 25. 00% (9/36), respectively. The positive expression rates of HIF-1α and Glut-1 in the basal-like, HER-2 over-expressing and normal-like subtypes were remarkably higher than that in Luminal A and Luminal B subtypes ( P<0. 004 5) and the expression of HIF-1a and Glut-1 was negatively correlated with the expression of ER (P<0. 01). In the ER-negative breast cancers, the positive expression rates of HIF-1a and Glut-1 in basal-like substype were much higher than that in the other sub-types (P<0. 004 5), and the expression of HIF-1α was positively correlated with expression of Glut-1 in basal-like breast carcinoma (P<0. 01). Conclusion The overexpression of HIF-1αand Glut-1 may be closely related to the ER-negative breast cancer and HIF-1α and Glut-1 might play an important role in the development of basal-like breast carcinoma.

Objective To study the expressions of hypoxia inducible factor-1 α (HIF-1 α) and carbonic anhydrase 9 (CA9) in different molecular subtypes of breast carcinoma and their relationships with basallike subtype.Methods The expressions of HIF-1α and CA9 were detected by immunohistochemistry in five subtypes of breast carcinoma (n =803).The relationships of the expressions of HIF-1α and CA9 with the clinicopathologic parameters of basal-like subtype and with the prognosis of patients were analyzed.Results The positive expression rates of HIF-1α and CA9 protein in breast carcinoma were much higher than those in paratumor breast tissues (43.96％ vs.3.86％,x2 =354.858,P ＜ 0.001;19.80％ vs.4.61％,x2 =86.495,P ＜ 0.001).The positive expression rates of HIF-1α in Luminal A,Luminal B,epidermal growth factor receptor-2 (HER-2) over-expression,basal-like and normal breast-like subtypes were 31.97％,25.00％,56.06％,77.89％ and 55.76％ respectively,and the positive expression rates of CA9 were 7.48％,5.56％,60.61％,40.00％ and 27.88％ respectively,with significant differences (x2 =88.628,P ＜ 0.001;x2 =147.128,P ＜0.001).The positive expression rates of HIF-1α and CA9 in estrogen receptor (ER)-negative breast carcinomas(HER-2 over-expression,basal-like and normal breast-like) were significantly higher than those in ER-positive subtypes (Luminal A and Luminal B,all P ＜ 0.005).There was a significant positive correlation between HIF-1 α and CA9 (C =0.315,P =0.001),and both were correlated with the lymph node metastasis (x2 =4.542,P =0.033;x2 =7.025,P =0.008),pTNM stage (x2 =5.390,P =0.020;x2 =10.179,P =0.001) and poor prognosis (x2 =4.353,P =0.037;x2 =6.056,P =0.014) of basal-like subtype.Conclusion Over-expressions of HIF-1α and CA9 may be related to the ER-negative breast cancer more closely,and both may play important roles in the occurrence and development of basal-like subtype.Overexpressions of HIF-1α and CA9 may suggest the poorer prognosis of patients with basal-like breast carcinoma.
