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)

Cord blood is a rich source of hematopoietic stem cells and could be potentially used for transplantation instead of conventional sources of stem cells (bone marrow or peripheral blood). Cord blood cells are successfully used in pediatric and adult patients, but their major limitation is the low number of hematopoietic stem cells for patients of large body(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)
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)
OBJECTIVE The invasive aspergillosis (IA) is a serious opportunistic infection caused by various species of Aspergillus in immunocompromised individuals. Basically, rapid and early diagnosis prevents IA progression. In this study we performed a Real Time PCR/ Fluorescence Resonance Energy Transfer (FRET) for diagnosis of IA in hematologic malignancies and(More)
Immunosuppression in acute myeloid leukemia (AML) is an important mechanism of tumor escape. CD200, as an immunosuppressive molecule, is overexpressed in some hematological malignancies and it has also been shown to be an independent prognostic factor in AML. In the current study, simultaneous CD200 expression and Foxp3+ regulatory T cell levels were(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)
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)
