Activation-induced cytidine deaminase (AID) induces somatic hypermutation (SHM), class switch recombination (CSR), and immunoglobulin gene conversion in B-lymphocytes. Here we report for the first time the expression of AID in healthy human B-lymphocytes and in B-cell non-Hodgkin lymphomas (B-NHL). AID mRNA expression in humans is restricted to the CD19(+)CD38(+)IgD(-) germinal center cells, na...
Intracellular lactate dehydrogenase (LD) isoenzyme patterns were studied in the malignant cells of patients with a variety of lymphoid malignancies. These were compared with intracellular LD isoenzyme patterns of normal lymphoid cells and were also correlated with immunologic cell surface marker characteristics. Results showed that, in general, the malignant B cells of Burkitt's lymphoma and th...
Further improvement of outcome in childhood acute lymphoblastic leukemia could be achieved by identifying additional high-risk patients who may benefit from intensified treatment. We earlier identified PTPRC (CD45) gene expression as a potential new stratification marker and now analyzed the prognostic relevance of CD45 protein expression. CD45 was measured by flow cytometry in 1065 patients tr...
Transcription factor IKZF1 (IKAROS) acts as a critical regulator of lymphoid differentiation and is frequently deleted or mutated in B-cell precursor acute lymphoblastic leukemia. IKZF1 gene defects are associated with inferior treatment outcome in both childhood and adult B-cell precursor acute lymphoblastic leukemia and occur in more than 70% of BCR-ABL1-positive and BCR-ABL1-like cases of ac...
background micrornas are small and non-coding rna molecules with approximately 22 nt in length that cause inhibition of translation or degradation of mrna. mir-155 is a kind of molecule with different functions, such as its role in proliferation, apoptosis, inflammation, differentiation, and immunity. one of its best known functions is apoptosis that affects on caspase-3 activity. the main aim ...
A 41-year-old man who had otherwise asymptomatic right scrotal swelling presented to our urology clinic. He had been diagnosed with T cell precursor lymphoblastic leukemia/lymphoma 2 years previously. On examination, his right epididymis was enlarged. A regular, homogeneous, slightly hypoechoic solid mass was observed at the right caput epididymis. This testicular mass measured approximately 7×...
A recombinant immunotoxin was constructed from the hybridoma antibody TH-69 directed against human CD7, a surface antigen of leukemic T cells. The antibody was subcloned as a single chain Fv (scFv) fragment and genetically linked to a truncated Pseudomonas exotoxin A fragment containing the catalytic domains II and III but lacking the receptor binding domain I. Domain I was replaced by the scFv...
Heparan sulfate proteoglycans (HSPGs) play important biological roles in cell-matrix adhesion processes and are essential regulators of growth actions. The expression of the different HSPGs in itself is tightly regulated providing strict controls on the activities of the bound ligands. Human liver is a target for a number of pathogens, and HSPGs have been demonstrated in several cases to play a...
Our previous study demonstrated that CopA3, a disulfide dimer of the coprisin peptide analogue (LLCIALRKK), has antibacterial activity. In this study, we assessed whether CopA3 caused cellular toxicity in various mammalian cell lines. CopA3 selectively caused a marked decrease in cell viability in Jurkat T, U937, and AML-2 cells (human leukemia cells), but was not cytotoxic to Caki or Hela cell...
Chronic lymphocytic leukaemia (CLL) is the most common B-cell malignancy in the western world and exists as subtypes with very different clinical courses. Myeloid cell leukemia 1 (Mcl-1) is one member of Bcl-2 family proteins that has been shown to be expressed in various tissues and malignant cells, including CLL, where its expression is significantly associated with a failure to achieve compl...
