Objective To investigate the synergistic regulation of KDM3B and JMJD1C in leukemia. Methods The expression level of JMJD1C and KDM3B were analyzed in multiple acute myeloid leukemia (AML) cell lines. AML cell lines NB4 and HL-60 were treated with Daminozide, followed by determination of H3K9 mono-methylation and di-methylation. AML cell lines NB4 and HL-60 were treated with Daminozide, ATRA (retinoid acid All-trans), C Vitamin and the expression of KDM3B and JMJD1C were detected by real-time quantitative PCR. Results The expression level of KDM3B and JMJD1C in the AML cell lines was negatively correlated. In NB4 and HL-60 cells treated by daminozide, H3K9 mono-methylation and di- methylation level showed a rising trend in these two cell groups. After treatment of NB4 cells with the 3 reagents, the level of mRNA of KDM3B was down-regulated while the level of mRNA of JMJD1C was up-regulated. In HL-60 cells treated by daminozide, the mRNA level of KDM3B was up-regulated and the mRNA level of JMJD1C was down-regulated. Conclusion The expression of KDM3B and JMJD1C is negatively correlated in patients with AML.

Recombinant expression vector pcDNA3-MCPCD59DP containing human membrane complement regulatory proteins(hCRPs) MCP and CD59 cDNA was constructed successfully by using two independent promoters.After transfected into NIH3T3 cells with calcium phosphate-DNA precipitate method,NIH3T3 pcDNA3-MCPCD59-DP transfectants were obtained by G418 selection.Extraneous genes integration was identified by PCR.The co-expression of human CD59 and MCP at both mRNA and protein levels was confirmed by using RT-PCR and Western blot analysis.Human MCP and CD59 cDNA were integrated in NIH3T3 pcDNA3-MCPCD59-DP genomic DNA after continuous 30 times passages,indicating that NIH3T3 pcDNA3-MCPCD59-DP were stable cell lines.Human complement-mediated cytolysis assays showed that NIH3T3 cells transfected stably with pcDNA3-CD59,pcDNA3-MCP,and pcDNA3-MCPCD59-DP were protected from C-mediated damage and co-expressed human MCP and CD59 provided more excellent protection against C-mediated attack as compared with either CD59 or MCP expressed alone.The dicistronic vector represents an effective and efficacy strategy to overcome C-mediated damage and has potential therapeutic value for effectively controlling complement activation and finally for preventing hyperacute rejection in clinical gene therapy.

Background Diabetes is one of the risk factors that leads to corneal neuropathy.Silent signal regulatory factor 1 (Sirt1) plays an important role in glucose metabolism,lipid metabolism,regulation of insulin secretion and is closely related to the nervous system disease.The relationship between Sirt1 and diabetic corneal neuropathy is not fully understood.Objective This study was to detect the expression of Sirtl in cornea and trigeminal ganglion with type 1 diabetes model mice and explore the association of Sirt1 expression with diabetic corneal neuropathy.Methods Eight C57BL/6-Ins2Akita/J male mice and eight wild-type C57BL/6 male mice in the same litter were selected as type 1 diabetes model group and control group,respectively.The mice of two groups were sacrificed in overdose anesthesia method at 12-month old.Histological examination of cornea and trigeminal ganglion was performed using hematoxylin and eosin staining.Expression and localization of Sift1 protein in cornea and trigeminal ganglion were detected using immunohistochemistry.Western blot assay and fluorescine quantitative PCR were respectively used to quantitatively analyze the expression of Sirt1 protein and Sirt1 mRNA.Results Trigeminal ganglion cells were uneven in size and shape with the loosened cellular arrangement and disorder neurofibrosis alignment,and the corneal epithelial cells were less in the C57BL/6-Ins2Akita/J mice,but the trigeminal ganglion cells and corneal epithelial cells were normal in wild-type C57BL/6 mice.Immunochemisty exhibited that Sirtl protein was expressed mainly in corneal epithelium and the expression of Sirtl protein was stronger in the C57BL/6 mice than that in C57BL/6-Ins2Akita/J mice.Fluorescine quantitative PCR assay showed that the gray scale value of Sirt1 mRNA in cornea in C57BL/6-Ins2Akita/J mice was lower than that of the wild-type C57BL/6 mice(0.56±0.03 vs.0.98±0.13) with significant difference (t =5.853,P =0.010).Western blot showed that the expression of Sirt1 protein in cornea was lower in C57BL/6-Ins2Akita/J mice than that of the wild-type C57BL/6 mice(0.78±0.017 vs.1.300±0.012) with significant difference(t =33.140,P =0.001).However,no significant differences were seen in the gray scale value of Sirt1 mRNA(2.45±0.18 vs.2.51±0.22) (t=0.587,P=0.599) and protein level(1.100±0.015 vs.1.110±0.017) (t =0.430,P=0.709) in trigeminal ganglion tissues between C57BL/6-Ins2Akita/J mice and wide-type C57BL/6 mice.Conclusions The corneal nerve and structure is abnormal in 12-month-old C57BL/6-Ins2Akita/J mouse.Sirt1 is involved in the pathogenesis of diabetic keratoneuropathy,suggesting that it may be a potential target.

Background and purpose: Neck lymph node metastasis, most of which presents in central neck compartment, is common in patients with papillary thyroid carcinoma (PTC). The objective of this study was to investigate the relationship between the number of dissected central neck lymph nodes and clinical outcome after radioactive iodine (RAI) ablation in pN1a PTC with no more than 5 lymph nodes involvement. Methods: A total of 167 PTC patients who had 1-5 proven metastatic lymph nodes according to postoperative pathological diagnosis were retrospectively analyzed, all of whom underwent total or near total thyroidectomy and central lymph node dissection. After a median follow-up period of 26 months, the clinical outcome of each patient was evaluated as excellent response (ER), indeterminate response (IDR), bio-chemical incomplete response (BIR), or structural incomplete response (SIR) according to the new American Thyroid As-sociation guidelines. The accumulative ER rate (ERn) was calculated in patients with different numbers of dissected lymph nodes (ERn was defined as the proportion of patients who achieved ER with the dissected lymph node number of ≤n). The relationship between the number of dissected central neck lymph nodes and ERn were investigated. Results: As the increase in the number of dissected central neck lymph nodes,there was also an overall increase in ERn, especially when n rose from 1 to 10. The values of ER1, ER5, ER10 and ER30 were 25.0%, 66.7%, 74.7% and 79.1%, respectively. Besides, the proportion of patients who achieved ER was higher in those with 10 or more dissected lymph nodes than in those with less than 10 (85.7% vs 73.3%, P=0.05). In the multivariate logistic regression analysis, both the dissected central lymph node number of ≥10 (OR=2.720, 95%CI: 1.052-7.033, P=0.039) and the level of preablation stimulated thyroglobulin (OR=0.955, 95%CI: 0.926-0.984, P=0.003) were shown to contribute independently to ER. Conclusion: As the increas-ing number of dissected central neck lymph nodes, the percentage of pN1a PTC patients that achieved ER after RAI ablation generally rises. In pN1a PTC patients with no more than 5 lymph nodes involvement, a central compartment dissection with 10 or more lymph nodes might help them achieve ER after RAI ablation.
