However, whether the strong and long-lasting T cell responses induced by the modified DCs could modulate the immunosuppressive tumour microenvironment has not been clarified. In this study, we explored the anti-tumour immunity of DCs modified by Socs1-shRNA lentiviral transduction combined with sustained expression of TRP2 in different tumour models. We showed that transfer Socs1-silenced or tumour antigen TRP2 persistent expressed DCs, or DCs modified by combination of Socs1-silencing and sustaining TRP2 expression prior to inoculation of tumour cells delayed B16 tumour cell growth, prolonged mouse survival and increased the ratio of CD8+ T/Treg as well as the CTL activity in tumours.

However, membrane-bound CD40L can be cleaved into a soluble form, sCD40L, which contributes to systemic inflammatory and cardiovascular diseases, and induces survival signals in the absence of protein synthesis block, suggesting a deleterious side effect of CD40L gene therapy. We generated a plasmid encoding non-cleavable human CD40L mutant (pcDNA3.1+-CD40L-M) to determine the direct anti-proliferative and pro-apoptotic effects in CD40-positive lung adenocarcinoma cell line A549, to verify activation of immature dentritic cells (DCs) by co-cultivation with the transfected A549 cells and to evaluate the lower expression of sCD40L relative to that of wild-type CD40L (CD40L-WT) transfectant in cell-free supernatants. These studies suggest that gene transfer of the membrane-stable CD40L mutant into CD40-positive cells may provide an efficient and safe method to treat non-small cell lung cancer', ' (AITL) is a rare and aggressive neoplasm clinically characterized by sudden onset of constitutional symptoms, lymphadenopathy, hepatosplenomegaly, frequent autoimmune phenomena, particularly hemolytic anemia and thrombocytopenia, and polyclonal hypergammaglobulinemia. The lymph node histological picture is also distinctive, constituted by a polymorphic infiltrate, a marked proliferation of high endothelial venules, and a dense meshwork of dentritic cells. The neoplastic CD4+ T-cells represent a minority of the lymph node cell population; its detection is facilitated by the aberrant expression of CD10. Almost all cases arbor an EBV infected B-cell population. Patients with AITL have a poor prognosis with conventional treatment, with a median overall survival of less than 3 years. Patients achieving a good clinical response seem beneficiate from a consolidation with high-dose therapy and autologous stem cell transplantation. Constitutional symptoms and autoimmune phenomena, and some times also the neoplastic masses may respond to immunosuppressive or immunomodulatory agents such as thalidomide', 'Survivin expression is a poor prognostic marker in a number of cancers. Clinical trials are currently underway evaluating anti-sense oligonucleotides against Survivin, immunotherapy using Survivin primed dentritic cells and peptide mimics that block interaction of Survivin with Hsp90 resulting in loss of Survivin protein stability. Additional approaches using ribozymes against Survivin mRNA, or dominant-negative cDNA to block Survivin function are in pre-clinical stages. Like many genes, Survivin is alternately spliced and a number of new splice variants have recently been identified. Expression of some of these splice variants correlates with loss of steroid receptors as well as the tumor suppressor p53, in some cancers, suggesting that like wild-type Survivin, at least some of these splice variants may also have prognostic relevance. This review will focus on the current understanding of the function of Survivin splice variants and their expression and sub-cellular localization in normal and neoplastic tissues as well as critically evaluating the potential toxicity of the Survivin directed therapies and their predicted effect on the alternatively spliced Survivin isoforms', ' Immunotherapy applying ex vivo-generated and tumor antigen-loaded dentritic cells has been successfully introduced in clinical vaccination protocols and has proven to be feasible and effective in some patients. A better understanding of how dentritic cells succeed to induce and modulate immunity is necessary to optimally exploit dentritic cells in anticancer vaccines. The authors will review novel insights in antigen loading, activation and migration of dentritic cells and their impact on the application of ex vivo-generated dentritic cell vaccines. In addition, novel means to exploit dentritic cells in cancer vaccines by loading and activation of dentritic cells directly in situ and possible obstacles that should be overcome to induce long-lasting immunity in therapeutic settings will be discussed'] | ["Another approach to cancer therapy takes advantage of the normal role of the dendritic cell as an immune educator. Dendritic cells grab antigens from viruses, bacteria, or other organisms and wave them at T cells to recruit their help in an initial T cell immune response. This works well against foreign cells that enter the body, but cancer cells often evade the self/non-self detection system. By modifying dendritic cells, researchers are able to trigger a special kind of autoimmune response that includes a T cell attack of the cancer cells. Because a cancer antigen alone is not enough to rally the immune troops, scientists first fuse a cytokine to a tumor antigen with the hope that this will send a strong antigenic signal. Next, they grow a patient's dendritic cells in the incubator and let them take up this fused cytokine-tumor antigen. This enables the dendritic cells to mature and eventually display the same tumor antigens as appear on the patient's cancer cells. When these special mature dendritic cells are given back to the patient, they wave their newly acquired tumor antigens at the patient's immune system, and those T cells that can respond mount an attack on the patient's cancer cells."] | [] |

What is the role of the histidine rich calcium binding protein (HRC) in cardiomyopathy? | ['The histidine-rich Ca-binding protein (HRC) is a Ca-storage protein in cardiac sarcoplasmic reticulum.

Furthermore, the frequency of spontaneous Ca(2+) sparks, which was reduced by HRC(WT), was increased by mutant HRC(S96A) under resting conditions although there were no spontaneous Ca(2+) waves under stress conditions. However, expression of the HRC(S96A) genetic variant in cardiomyocytes from a rat model of postmyocardial infarction heart failure induced dramatic disturbances of rhythmic Ca(2+) transients.

Exonic splicing enhancers (ESEs) activate pre-mRNA splicing by promoting the use of the flanking splice sites. Some of these variants may have an effect on pre-mRNA splicing, either by altering degenerate positions of splice site sequences or by affecting intronic or exonic splicing regulatory sequences such as exonic splicing enhancers (ESEs). For inherited disease, the main mechanism responsible for the splicing defect is splice site loss, whereas for cancer the predominant mechanism of splicing disruption is predicted to be exon skipping via loss of exonic splicing enhancers or gain of exonic splicing silencer elements.

What is GDF10? | ['We have identified a new member of the transforming growth factor-beta (TGF-beta) superfamily, growth/differentiation factor-10 (GDF-10), which is highly related to bone morphogenetic protein-3 (BMP-3).

Decreased AMPK activity and the subsequent reduction in cardiac autophagy are central to the development of diabetic cardiomyopathy. In fact, dissociation of Bcl-2 from Beclin1 may be an important mechanism for preventing diabetic cardiomyopathy via AMPK activation that restores autophagy and protects against cardiac apoptosis. In addition, genetic inhibition of AMPK in cardiomyocytes attenuates cardiac autophagy, exacerbates cardiac dysfunction and increases mortality in diabetic mice. The modulation of AT-1R/AMPK-MAPK pathway might play crucial roles for the pathogenesis of diabetic cardiomyopathy and it could become an important therapeutic target to ameliorate the diabetic cardiomyopathy. Stimulation of AMPK by metformin or trimetazidine administration may represent a novel approach to treat diabetic cardiomyopathy.'] | [] |
