Inactivation of Dickkopf-3 (DKK3) is closely associated with a poor prognosis in various solid tumor and hematologic malignancies. Promoter hypermethylation is one potential cause of DKK3 inactivation. However, whether other mechanisms lead to DKK3 inactivation and the subsequent effects of these inactivations on cell proliferation and the Wnt signaling pathway in adult B acute lymphoblastic le...
During development many of neurons die by the phenomenon named programmed cell death or apoptosis and this reaction is regulated by neurotrophin (BDNF, NGF, NT3 and NT4/5). These neurotrophins bind to two different classes of transmembrane receptor proteins, the Trks and P75 NTR. Axotomy can induce apoptosis after birth and deprenyl is a an inhibitor of monoamineoxidase type-B and seems to act ...
B-acute lymphoblastic leukemia (B-ALL) is a malignant disorder characterized by the abnormal proliferation of B-cell progenitors. Philadelphia chromosome-positive (Ph+) B-ALL is a subtype that expresses the Bcr-Abl fusion protein which represents a negative prognostic factor. Constitutive activation of the phosphatidylinositol 3-kinase/Akt/mammalian target of rapamycin (PI3K/Akt/mTOR) network i...
Background: Hemophilia B is a bleeding disorder with a recessive X-linked inheritance pattern, in which the infected individuals have low levels of factor IX in their plasma. Affected individuals may have bleeding episodes after trauma or spontaneously considering the plasma level of factor IX. In order to prevent these episodes and to control bleeding, they should use coagulation factor concen...
The PI3K/Akt/mTOR pathway is activated in a variety of human tumors including B-cell non-Hodgkin lymphoma (B-NHL). Targeting this pathway has been validated in solid and hematological tumors. In the present study, we demonstrated that PF-04691502, a novel PI3K/mTOR inhibitor has potent activity in a panel of aggressive B-NHL cell lines including diffuse large B-cell lymphoma (DLBCL) and mantle ...
In tumor cells, the serine protease granzyme B is the primary mediator of apoptosis induced by cytotoxic T lymphocytes (CTLs)/natural killer (NK) cells. The human intracellular serpin proteinase inhibitor 9 (PI9) is the only known human protein able to inhibit the proteolytic activity of granzyme B. When present in the cytoplasm of T lymphocytes, PI9 is thought to protect CTLs against apoptosis...
Activated B-cell-like diffuse large B-cell lymphoma relies on B-cell receptor signaling to drive proliferation and survival. Downstream of the B-cell receptor, the key signaling kinases Bruton's tyrosine kinase and phosphoinositide 3-kinase δ offer opportunities for therapeutic intervention by agents such as ibrutinib, ONO/GS-4059, and idelalisib. Combination therapy with such targeted agents c...
The direct effect of immunosuppressive drugs calcineurin inhibitor (Tacrolimus, TAC) and mTOR inhibitor (Sirolimus, SRL) on B cell activation, differentiation and proliferation is not well documented. Purified human B cells from healthy volunteers were stimulated through the B Cell Receptor with Anti-IgM + anti-CD40 + IL21 in the absence / presence of TAC or SRL. A variety of parameters of B ce...
Rheumatoid arthritis is a chronic inflammatory destructive disorder that affects the joints, muscles, and tendons accompanying various extra-articular manifestations. Traditional disease-modifying anti-rheumatic drugs (DMARDs) represent basic treatment for rheumatoid arthritis. Over last 20 years, biologic DMARDs (tumor necrosis factor inhibitors, interleukin-1 interleukin-6 T cell B inhibitors...
چکیده بیماری هپاتیت b شایع ترین عفونت ویروسی مزمن شناخته شده انسان و شایع ترین علت سیروز کبدی و اصلی ترین عامل کارسینوم کبد در ایران به شمار می رود. اگرچه فاکتورهای تعیین کننده پیامد عفونت با ویروس هپاتیت b (hbv) به خوبی شناخته نشده اند اما پاسخ میزبان و عوامل محیطی نقش تعیین کننده ای در روند بیماری دارند. همچنین بررسی های انجام شده در تقابل پاسخ میزبان و ویروس، نقش موتاسیون های ویروسی در پات...
