Background: Growing evidence has demonstrated that microRNAs have a major effect on development of different types of cancer including AML. The overexpression of miR-625 could decrease tumorgenesis of acute myeloid leukemia cell lines through Integrin-linked kinase signaling pathway and reducing the associated oncogenes.  The aim of this study is to evaluate the effect of hsa-miR-625 upregulation on apoptosis and proliferation of KG1 cell line via ILK signaling pathway. Methods: The KG-1 cell line was transfected with pLenti-III-premir625-GFP through viral method. Then, expression of miR-625 and genes were analyzed by quantitative PCR. Western blotting was used to evaluate for the protein level. Apoptosis was investigated by flow cytometry. Cell cycle analysis with PI and CCK-8 assay were performed to evaluate proliferation. Results: KG-1 cells transfected with pLenti-III-pre mir625-GFP construct showed a significant increase in cell apoptosis. Gene expression of ILK and NF-κB were downregulated and AKT, c-fos, Caspase3, cyclin D1, KLF-4, OCT-4 and Nanog were upregulated but no alteration in GSK3 expression profile was observed. Downregulation of NF-κB and upregulation of Caspase 3 and p-β-catenin protein levels were indicated (p<0.05). Conclusion: MiR-625 can be a promising approach to aid in the treatment of AML. However, further studies are required in this respect.  相似文献

Diabetes has been classified mainly into types 1 and 2. Some type 2 diabetes patients, when developing ketosis, have been labeled as having atypical diabetes. Lately, syndromes of ketosis-prone diabetes, primarily in patients who we previously classified as type 2 diabetics, have emerged, and calls are being made to even reclassify diabetes. This mini-review will extensively deal with the historical, molecular, phenotypical, and clinical basis of why ketosis-prone diabetes is different than the traditional principles of type 1 and 2 diabetes and should be classified as such. Clinicians, especially those who are not diabetologists or endocrinologists, as well as hospitalists, intensivists, and primary care providers, will greatly benefit from this review.  相似文献

ObjectivesCurrent service delivery models for second-trimester medical abortion typically include routine inpatient admission and overnight stays. To assess the feasibility of a day-service model, we evaluated outpatient administration of abortion medications and analyzed the proportion of clients who could avoid an overnight stay. We also examined additional key elements of medical abortion care to evaluate the practicality of this model.Study designWe pooled data from six clinical studies of second-trimester medical abortion conducted by Gynuity over the past 10 years. We include 868 individuals receiving mifepristone–misoprostol abortion between 13 and 22 weeks’ gestation.ResultsAt 8 h post misoprostol initiation, 309/521 (59.3%) participants at 13-18 weeks' gestation had a successful abortion; by 10 h, 382/521 (73.3%) were successful. Taking the mifepristone at home lowered neither the efficacy of the method nor satisfaction with the experience. Nonphysician providers played a significant role in the provision of care. Needed interventions were relatively rare; serious complications were very rare.ConclusionsOur findings support the provision of second-trimester medical abortion in a day-clinic setting, especially at ≤18 weeks' gestation. Such a model could increase access to quality care in many settings.ImplicationsSecond-trimester medical abortion can safely and effectively be offered as a day service. Nonphysician providers are well suited to provide the majority of care. Developing guidelines for a 1-day model could increase access to quality care in many settings worldwide.  相似文献

Objective: To identify serodiagnosis and quantification of Toxoplasma gondii(T. gondii) infection among pregnant women in Salmas, northwest of Iran. Methods: In this crosssectional study, 276 blood samples were collected from pregnant women referred to the health care centers in Salmas city. The demographic variables were also recorded. Titers of antiToxoplasma IgM and IgG antibodies(Ab) were determined using the chemiluminescence immunoassay. Quantitative real-time PCR targeting the T. gondii repeated element gene was also performed on the blood sample. Results: Out of all, 19.92%(55/276) and 2.17%(6/276) patients were seropositive for anti-Toxoplasma IgG and IgM Ab, respectively. Moreover, the presence of T. gondii DNA was observed in 12.31%(34/276) blood samples. A significant relationship was observed between the IgG Ab seropositivity and contact with the cat as a risk factor(P=0.022). Conclusions: The seroprevalence rate of T. gondii infection in pregnant women is relatively low. Consequently, the seronegative pregnant women are at risk, and a considerable rate of positive blood samples for the presence of parasite's DNA should not be ignored. Besides, quantitative real-time PCR could be considered as an accurate method for diagnosis of acute toxoplasmosis especially when the precise results are of the most importance in pregnancy. Limiting contact with cats is also suggested for pregnant women.  相似文献
