, which correlated with the TNM phases. reported that three gml DcR3 markedly induced Gemzar the phosphorylation of ERK and p38. In accordance with these reviews, we propose that DcR3 and ERK12 are closely related. The DcR3 genes closely correlated with the occurrence and growth of many types of tumors. Within this study we investigated the expres sion level and place of DcR3 and ERK12 in gastric cancer patients of different ages, gender, stage and vary entiation, to investigate the romantic relationship in between DcR3 ERK12 and gastric cancer occurrence and growth. Furthermore, we deliver ideas for clinical diagnosis of gastric cancers.
Solutions Clinical samples Tumors had been from gastric cancer patients who were undergone endoscopic biopsy or curative operations in Zhongshan hospital affiliated with Xiamen university. Tumor tissues from which DNA and protein had been isolated were from fresh specimen of resection EGFR surgical procedure. All sam ples have been obtained with patient consent and approval of the Committee on Healthcare Ethics of Zhongshan Hospital Xiamen University. Mice All of the experiments had been carried out applying 6 8 weeks male nude mice purchased from Model Animal Study Center of Health-related University Xiamen University. Each of the ani mals were housed under specific pathogen free conditions with frequent entry to water and chow. All experimental procedures were carried out following the approval in the Animal Care and Use Committee of Xiamen University. Cell culture The human gastric cancer cell line BGC823 was most important tained in our laboratory, which was cultured in flasks with Dulbeccos modified Eagles medium sup plemented with 10% fetal bovine serum, and 1% penicillin streptomycin at 37 C in an humidified atmos phere of 5% CO2.
Reagents DMEM, FBS and penicillin streptomycin have been purchased from Hyclone Corporation. Hematoxylin and eosin assay kit were purchased from Chemicon Global, Inc. ERK12 and DcR3 Abs had been obtained from Santa Cruz Bio engineering. RT RCR reagents had been purchased from TaKaRa. The primer sequence was synthesized DNA synthesis from Sangon. In vivo animal tumor versions Tumors were generated in male nude mice by intramus cular injection of BGC823 cells to the correct flank. Tumor measurements had been converted to tumor volume by the formula, where L and W will be the length and width, respectively. Measurements have been produced by using a vernier caliper. All tumor bearing mice have been divided randomly into groups. RT PCR and Western blotting analysis for examining the expression of DcR3ERK Complete RNA of DcR3 and ERK12 was extracted from stimu lated cells utilizing Trizol. To measure ERKDcR3 gene copy variety, DNA from fresh tumor samples was analyzed with RT PCR.
The samples were denatured at 95 C for 4 min, followed by 30 cycles of amplification. The product was a 921 bp fragment. cytokines as indicated assay. Twenty 5 micrograms of total lysate was fractionated by SDS Page and subjected to Western blotting examination making use of the anti ERK or anti DcR3 mAb. Immunohistochemistry evaluation to the expression of DcR3 and ERK12 Tumor tissues had been fixed in the formaldehyde medium and embedded in paraffin. Sections 6 mm thick were mounted on glass slides pretreated with 0.
