objective(s): t-cell acute lymphoblastic leukemia (t-all) is an aggressive hematologic malignant tumor. administration of chemical compounds influencing apoptosis and t cell development has been discussed as promising novel therapeutic strategies. valproic acid (vpa) as a recently emerged anti-neoplastic histone deacetylase (hdac) inhibitor and pioglitazone (pgz) as a high-affinity peroxisome p...

t cell acute lymphoblastic leukemia (all) is an invasive disease with a higher incidence in children and adolescents. in terms of immunophenotype, t-all is positive for cd2, cd7, cd34 and hla-dr, and the level of these markers is increased with increasing age. in addition, the myeloid markers (cd13, cd33) are sometimes expressed in t-all. in this study, we introduce a rare case of a 28-year-old...

background: mature t/ nk-cell neoplasms are a rare group of disorders and their presentation as leukemia is even rarer. most of the previous studies have focused on mature b-cell lineage leukemias and there is a paucity of data on mature t/nk-cell lineage leukemias. we, therefore, planned this study to analyze their spectrum, frequency, morphology and immunophenotypic features. methods: all cas...

T-Cell Acute Lym-phoblastic Leukemia In article number 2205854, Jingjing Ye, Min Ji, Chunyan and co-workers observed aberrant adipogenesis in the bone marrow of chemotherapy-treated T-cell acute lymphoblastic leukemia (T-ALL) patients, differentiated-adipocytes attract support residual T-ALL cells. Last, an SREBF1 inhibitor demonstrates superior improvement on therapeutic effect dexamethason by...

T-cell acute lymphoblastic leukemia is an aggressive hematologic malignancy which is usuallyassociated with unfavorable prognosis particularly in patients with refractory/relapsed disease.Therefore, development of novel therapeutic strategies is highly required for improving theoutcome of these patients. Although there are several studies evaluating the efficacy of proteasome<...

the study of tumor viruses paves the way for understanding the mechanisms of virus pathogenesis, including those involved in establishing infection and dissemination in the host tumor affecting immune-compromised patients. the processes ranging from viral infection to progressing malignancy are slow and usually insufficient for establishment of transformed cells that develop cancer in only a mi...

Background and aim: Adult T cell leukemia/lymphoma (ATLL) is an aggresive malignancy which may occur in human T lymphotropic virus1(HTLV1) infected persons. HTLV1 is endemic in Khorasan with prevalence of 2.3% in general population. Since specific cutaneous manifestations of lymphoma may occur in a significant number of patients, we studied ATLL patients in Mashhad.Mate...

Two IgM monoclonal antibodies (MAb) with strong reactivity for granulocytes and to a lesser extent for lurkat cell lines were established by immunizing BALBI c mice with a histiocytic cell line (UY37). These two MAbs (designated as 6C9 and 4C4) reacted with blast cells of T-acute lymphoblastic leukemia (T-ALL) and acute myelogenous leukemia (AML) patients as well as leukemic cells from pat...

micrornas are 19-22 nucleotide rnas involved in such important processes as development, proliferation, differentiation and apoptosis. different mirnas are uniquely expressed in lymphoid t cells, and play a role indevelopment and differentiation of various subtypes by targeting their target genes. recent studies have shown that aberrant mirna expression may be involved in t cell leukemogenesis ...
