BACKGROUND A hot new topic in medical treatment is the use of mesenchymal stem cells (MSC) in therapy. The low frequency of this subpopulation of stem cells in bone marrow (BM) necessitates their in vitro expansion prior to clinical use. We evaluated the effect of long term culture on the senescence of these cells. RESULTS The mean long term culture was(More)
Patients with glioblastoma multiforme (GBM) have poor therapeutic outcomes despite their current therapy. In an attempt to increase the efficacy of therapy for GBM, we studied the efficacy of arsenic trioxide (ATO), a newly introduced treatment for glioma, combined with silibinin, a natural polyphenolic flavonoid, in the GBM cell line, U87MG. The(More)
BACKGROUND The standard treatment for decompensated liver cirrhosis is liver transplantation. However, it has several limitations. Recent animal studies suggest that bone marrow stem cell transplantation can lead to regression of liver fibrosis. The objective of this study was to determine the safety and feasibility of autologous bone marrow-mesenchymal(More)
Prostate cancer is the frequent non-cutaneous tumor with high mortality in men. Prostate tumors contain cells with different status of androgen receptor. Androgen receptor plays important roles in progression and treatment of prostate cancer. Aurora B kinase, with oncogenic potential, is involved in chromosome segregation and cytokinesis, and its inhibition(More)
MicroRNAs (miRNAs) are involved in cancer pathogenesis, apoptosis, and cell growth, and these miRNAs are thought to be functional as oncogenes and/or tumor suppressors in the gene regulatory networks. We studied the potential contribution of miRNAs in acute promyelocytic leukemia (APL) cell NB4 during the apoptosis induction by arsenic trioxide (ATO). The(More)
Since all-trans retinoic acid (ATRA) has shown promising results in differentiation therapy, the present study was designed to investigate the effects of ATRA on thyroid carcinoma and to evaluate the effectiveness of ATRA in redifferentiation induction of thyroid carcinoma. Therefore, we investigated cell growth rate, morphological and nuclear: cytoplasmic(More)
BACKGROUND The aim of this study is to evaluate the prognostic factors of overall survival (OS) after haematopoietic stem cell transplant (HSCT) in acute lymphoblastic leukaemia (ALL) patients using accelerated failure time (AFT), Cox proportional hazard (PH), and Cox time-varying coefficient models. METHODS 206 patients were enrolled after HSCH in(More)
Pro-inflammatory cytokines including tumor necrosis factor alpha (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) play an important role in the development of hematopoietic stem cell transplantation (HSCT) complications. We explored the effect of Selenium as an antioxidant and anti-inflammatory agent on pro-inflammatory cytokines levels in HSCT(More)
Neuroblastoma is the most common solid tumor in children. Current therapy modalities have resulted in little amelioration in the cure rate of neuroblsatoma and therefore, outlining biologically based therapies for neuroblastoma remains of main priority. This study was carried out to appraise the impeding effects of silibinin, a potent anti-cancer agent, on(More)
HTLV-I associated adult T-cell leukemia/lymphoma (ATL) carries a dismal prognosis due to chemo-resistance and immuno-compromised micro-environment. The combination of zidovudine and interferon-alpha (IFN) significantly improved survival in ATL. Promising results were reported by adding arsenic trioxide to zidovudine and IFN. Here we assessed Th1/Th2/Treg(More)
