We have recently reported that methionine adenosyltransferase (MAT) in resting human peripheral blood T-cells is primarily present in the form of a precursor which we named lambda. This protein decreases upon cell stimulation, as both MAT activity and the amount of the catalytic alpha/alpha' subunits of the enzyme increase. When resting cells are activated by phytohemagglutinin, the decrease in...

BACKGROUND AND OBJECTIVES The apoptotic Bcl-2 family member Hrk is transcriptionally silenced via DREAM in hematopoietic progenitor cell lines, and is specifically induced after growth factor withdrawal. Given that expression of Hrk is sufficient to induce apoptosis, we studied the expression of this apoptotic protein and its regulatory mechanism in human leukemia cells. DESIGN AND METHODS K5...

Notch signaling, which is driven by the Notch1 receptor, plays an essential role in the pathogenesis and stroma-mediated drug resistance of T-cell acute lymphoblastic leukemia (T-ALL). However, little is known about the roles of Notch ligands in the survival or drug resistance of T-ALL cells. In the present study, isolated mesenchymal stem cells (MSCs) from human umbilical cord (hUC) samples, t...

background and objective: vascular endothelial growth factor (vegf) is a cytokine which is overexpressed in many malignant cancers including leukemia. vegf plays an important role in tumor invasion and metastasis. determination of the pattern of vegf expression in human leukemic cell lines could be useful not only in screening of new antileukemic agents but also to study the mechanism of their ...

Background: Doxorubicin (DOX)-induced cardiotoxicity appears to be a growing concern for extensive use in acute lymphoblastic leukemia (ALL). The new combination treatment strategies, therefore might be an effective way of decreasing its side effects as well as improving efficacy. AMG232 (KRT-232) is a potential MDM-2 inhibitor, increasing available p53 through disturbing p53-MDM-2 interaction....

This investigation evaluated the antileukemia properties of a zerumbone (ZER)-loaded nanostructured lipid carrier (NLC) prepared by hot high-pressure homogenization techniques in an acute human lymphoblastic leukemia (Jurkat) cell line in vitro. The apoptogenic effect of the ZER-NLC on Jurkat cells was determined by fluorescent and electron microscopy, Annexin V-fluorescein isothiocyanate, Tdt-...

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...

Conventional treatment for cancer such as surgical resection and chemotherapy can cause damage in cases with advanced cancers. Moreover, the identification of tumor-specific targets has great importance in T-cell therapies. For decades, T cell activity has been stimulated to improve anti-tumor activity. Bispecific antibodies have attracted strong interest from pharmaceutical companies, for thei...
