The B-cell receptor pathway (BCR) is aberrantly activated in select B-cell malignancies. This knowledge has allowed for the development of inhibitors of different crucial steps of this pathway. Bruton's tyrosine kinase (BTK) is a key component of BCR signaling and functions as an important regulator
OBJECTIVE
Patients with primary Sjögren's syndrome (SS) are at greater risk of developing lymphoma. This study was undertaken to evaluate whether the Fms-like tyrosine kinase 3 ligand (Flt-3L) might be associated with lymphoma in primary SS.
METHODS
Serum levels of Flt-3L were measured in 369
Large-cell anaplastic lymphoma is a subtype of non-Hodgkin's lymphoma characterized by the expression of CD30. More than half of these lymphomas have a chromosomal translocation, t(2;5), that leads to the expression of a hybrid protein comprised of the nucleolar phosphoprotein nucleophosmin (NPM)
The murine lymphoma cell line LSTRA expresses high levels of a membrane-associated tyrosine protein kinase, which we now show to be acylated by [3H]myristate in vivo. This [3H]myristate-labeled tyrosine protein kinase is immunoprecipitated from detergent extracts of postnuclear particulate fractions
c-kit plays an important role in proliferation, survival and differentiation of hematopoietic progenitor cells. In human hematopoietic malignancies, c-kit is mostly expressed by progenitor cell neoplasms and seldom by mature cell neoplasms. Aim of this study was to evaluate c-kit expression in
Anaplastic lymphoma kinase (ALK) is a novel neuronal orphan receptor tyrosine kinase that is essentially and transiently expressed in specific regions of the central and peripheral nervous systems, suggesting a role in its normal development and function. To determine whether ALK could play a role
BACKGROUND
Aberrant expression of the RON receptor tyrosine kinase is associated with tumor progression and carcinogenesis. The aims of this study were to determine the role and functional mechanisms of RON in Burkitt lymphoma (BL) and to document its potential as a therapeutic target.
METHODS
RON
BACKGROUND
The Bruton tyrosine kinase (BTK) is a central hub in the B cell receptor (BCR) pathway and strongly influences B cell maturation, differentiation and proliferation. Not surprisingly, BTK plays an essential role in the pathogenesis of various B cell lymphomas. Inhibitors of BTK have
Bruton's tyrosine kinase (Btk) is a member of the Tec family of protein tyrosine kinases involved in B cell development and proliferation in neoplastic human lymphoid tissues. We used immunohistochemistry to evaluate a polyclonal anti-Btk antibody on formalin-fixed paraffin-embedded tissue blocks.
In this review, we explore insights into the pathophysiology of Bruton tyrosine kinase inhibitor (BTKi) resistance in mantle cell lymphoma, and consider potential therapeutic targets. We review the possible clinical benefits of giving BTKis alongside other novel therapies, and evaluate clinical data
Spleen tyrosine kinase (SYK) has emerged as a potential molecular target for the treatment of B-lineage leukemias and lymphomas. Here, we provide an overview of the current state of knowledge regarding the regulatory signaling function of SYK and its role in the pathogenesis of B-lineage lymphoid
Non-Hodgkin lymphomas usually become resistant to chemotherapy and relapse due to the their intense antiapoptotic robustness. Furthermore, the slow growth of these malignancies limits the effectiveness of drugs aimed mainly at the proliferative pathways. Because protein tyrosine kinases (PTKs) play
CD30 is a transmembrane receptor of the nerve growth factor/tumor necrosis factor receptor superfamily. Its expression associated with Hodgkin's lymphoma and a subset of non-Hodgkin's lymphoma. Recently, its ligand (CD30L) has been cloned. CD30L enhances the proliferation of peripheral T cells and
Anthracycline-containing regimens, namely cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) or CHOEP (CHOP + etoposide), represent the current standard of care for patients with newly diagnosed peripheral T-cell lymphomas (PTCLs), although responses are unsatisfactory. Anaplastic lymphoma kinase (ALK), an oncogenic receptor tyrosine kinase, has emerged as a therapeutic target in solid and hematologic tumors. Although several ALK inhibitors have gained recent approval for therapy, non-invasive indicators of target engagement or for use as predictive biomarkers in
