RESUMO
Purpose To investigate the expression of forkhead box M1 (FOXM1) in human colorectal cancer(CRC) tissues,and to analyze the correlation between its expression and clinicopathological parameters and prognosis of CRC.Methods The expression of FOXM1 was examined in 297 cases of CRC tissues and 80 cases of normal peritumoral tissues by immunohistochemistry of SP.Western blot was used to detect the expression of FOXM1 in 20 cases of fresh CRC tissues and the corresponding normal peritumoral tissues.Results The expression of FOXM1 was significantly higher in CRC tissues (60.6％) compared with normal peritumoral tissues (17.50％,P ＜ 0.01).The positive expression of FOXM1 was related to the depth of invasion,lymph node metastasis,intravascular cancer embolus,distant metastasis and TNM stage (P ＜ 0.05).However,there was no correlation with age,sex,tumor location,tumor size,tumor differentiation degree,CEA and CA199 (P ＞0.05).The relative expression levels of FOXM1 protein was also significantly higher in CRC tissues (0.855 ± 0.063) compared with corresponding normal peritumoral tissues (0.150 ± 0.041,P ＜0.01).The 3-year overall survival of CRC patients with FOXM1 expression was significantly lower than that of patients without FOXM1 expression (P＜0.01),and FOXM1 is an independent prognostic factor for CRC.Conclusion The overexpression of FOXM1 protein in CRC tissues correlate with the clinicopathological characteristics and prognosis.FOXM1 may play an important role in the occurrence and metastasis of CRC,and it may be a new tumor marker and potential therapeutic target for CRC.
RESUMO
<p><b>OBJECTIVE</b>To investigate the possible mechanism of compound Chinese sour taste herbs (CS) in preventing and ameliorating diabetic macroangiopathy by analyzing the effects of CS on the deposition of advanced glycation end products (AGEs) and gene expression of receptor for advanced glycation end products (RAGE) in the aorta tissue of rats with type 2 diabetes mellitus (T2DM).</p><p><b>METHODS</b>Rat model of T2DM was established by peritoneal injection of streptozotocin (STZ) and high caloric diet feeding. Experimental SD rats were divided into the normal group, the model group, the aminoguanidine (AG) group, and the CS group. At the end of the 8th and 12th week, the fasting blood glucose (FBG) was measured by glucose oxidase method; content of AGEs and collagen in aorta detected by fluorescent method and gene expression of RAGE in aorta determined by Real-time PCR method.</p><p><b>RESULTS</b>FBG, AGEs and collagen contents and RAGE expression in aorta of model rats were all higher than those in the normal control group (P <0.05), while all these indices were lower in the CS group than in the model group (P<0.05).</p><p><b>CONCLUSION</b>CS could realize the goal for preventing and ameliorating diabetic macroangiopathy by way of suppressing the production of AGEs and down-regulating the gene expression of RAGE in aorta of T2DM rats.</p>
