Abstract
Apoptosis signal regulated kinase 1 (ASK1, also known as MAP3K5) is a member of the mitogen activated protein kinase kinase kinase (MAP3K) family. Since its first isolation from a human macrophage library in 1996, its research has been ongoing for over 25 years. A large number of reports have revealed that ASK1, as a key activator of the p38 mitogen-activated protein kinase and c-Jun N-terminal kinase (JNK) signaling cascade, responds to various stressors, and its inhibitors have important potential value in the treatment of diseases such as inflammation, cancer, and the nervous system and so on. This review summarizes the recent development in this field, including the structure and signaling pathways of ASK1, with a particular focus on the structure-activity relationships, and the hit-to-lead optimization strategies.

Abstract
Acute myeloid leukemias (AML) are a group of aggressive hematologic malignancies resulting from acquired genetic mutations in hematopoietic stem cells that affect patients of all ages. Despite decades of research, standard chemotherapy still remains ineffective for some AML subtypes and is often inappropriate for older patients or those with comorbidities. Recently, a number of studies have identified unique mitochondrial alterations that lead to metabolic vulnerabilities in AML cells that may present viable treatment targets. These include mtDNA, dependency on oxidative phosphorylation, mitochondrial metabolism, and pro-survival signaling, as well as reactive oxygen species generation and mitochondrial dynamics. Moreover, some mitochondria-targeting chemotherapeutics and their combinations with other compounds have been FDA-approved for AML treatment. Here, we review recent studies that illuminate the effects of drugs and synergistic drug combinations that target diverse biomolecules and metabolic pathways related to mitochondria and their promise in experimental studies, clinical trials, and existing chemotherapeutic regimens.

Abstract
Acute lymphoblastic leukemia (ALL) is the most common childhood cancer and the leading cause of cancer-related death in children and adolescents. Minimal residual disease (MRD) is a strong, independent prognostic factor. The objective of this study was to identify molecular signatures distinguishing patients with positive MRD from those with negative MRD in different subtypes of ALL, and to identify molecular networks and biological pathways deregulated in response to positive MRD at day 46. We compared gene expression levels between patients with positive MRD and negative MRD in each subtype to identify differentially expressed genes. Hierarchical clustering was applied to determine their functional relationships. We identified subtype-specific gene signatures distinguishing patients with positive MRD from those with negative MRD. We identified the genes involved in cell cycle, apoptosis, transport, and DNA repair. We also identified molecular networks and biological pathways dysregulated in response to positive MRD, including Granzyme B, B-cell receptor, and PI3K signaling pathways.

Abstract
Integrins are a large family of heterodimeric proteins that are involved in cell adhesion, migration, and proliferation. Integrin diversity and function is regulated by alternative splicing. Membrane-bound and truncated β3-integrins were shown to be key players in cancer metastasis. However, the immunomodulatory functions of the soluble (s) β3-integrin have not been investigated yet. In this study, we described a novel form of sβ3-integrin in acute myeloid leukaemia (AML) patients. Furthermore, we assessed the role of the sβ3-integrin in the modulation of natural killer (NK)-cell activity. Levels of sβ3-integrin were analysed in plasma samples of 23 AML patients and 26 healthy donors by ELISA. The capacity of sβ3-integrin to regulate NK cell activity was investigated using proliferation, cytokine secretion, and cytotoxicity assays. Circulating sβ3-integrin was detected in the plasma of 8 AML patients. NK cells showed significantly higher proliferation rates after stimulation with sβ3-integrin and IL-2, IL-15 (73%). Significant increases in the NK cells’ secreted levels of TNF-α, IFN-γ were measured in presence of sβ3-integrin. In addition, sβ3-integrin caused the upregulation of Granzyme B transcripts levels as well as FasL expression levels in NK cells. Most importantly, significantly higher K562 or AML blast target cell lysis rates were observed when NK cells were exposed to sβ3-integrin. This study reports the identification of a novel sβ3-integrin in AML patients and provides novel insights into its role in the immunomodulation of NK cell activity.

Abstract
Diabetic retinopathy (DR) has mainly been regarded as a microvascular disease that is caused by hyperglycaemia and characterized by retinal vascular leakage, macular oedema and preretinal neovascularisation. Increasing clinical evidence from electroretinographic, contrast sensitivity, perimetric, and colour vision studies suggest that neuronal changes may occur prior to clinically detectable microvasculopathy. Thus, there may be a primary neurodegenerative process which contributes to loss of vision in DR. Neuronal apoptosis in DR has been reported both in vivo and in vitro. Consequently, neuroprotection in DR may be a valuable therapeutic target. This review outlines the recent new concepts of neurodegeneration in the pathogenesis of DR, particularly emphasising its potential for new therapeutic approaches.

Abstract
Transforming growth factor-beta 1 (TGF-β1) is a cytokine which exerts a wide range of biological activities by initiating downstream signaling. As transmembrane receptors, TGFBRⅠ, TGFBRⅡ and TGFBRⅢ have been shown to play an important role in mediating TGF-β1 signal transduction. Owing to roles in promoting cell growth and development, alterations in TGF-β1 and its receptors may result in many diseases, especially tumors. Hepatocellular carcinoma (HCC) is a common malignant solid tumor with high risk of metastasis and recurrence and is associated with a high fatality. Recent studies point to a close relationship between hepatocellular carcinoma and the dysregulation of TGF-β1 signaling pathway. The changes in the levels of TGF-β1 and its receptors in tumor microenvironment may facilitate the invasive potential of HCC. In this article we mainly summarize the structure and function of TGF-β1 and its receptors and assess their role in metastasis and recurrence of hepatocellular carcinoma.

Abstract
This study was performed to analyze the effect of etanercept, the soluble tumor necrosis factor-alpha (TNF-alpha) receptor, on the serum levels of several chemokines including monocyte chemotactic protein-1 (MCP-1), regulated upon activation normal T expressed and presumably secreted (RANTES), and granzyme B in rheumatoid arthritis (RA) patients. Twenty-eight patients with RA were administered etanercept once or twice a week for more than 6 months. Clinical and laboratory parameters were measured and serum levels of MCP-1, RANTES, and granzyme B were determined using enzyme-linked immunosorbent assay (ELISA) kits at baseline and at 3 and 6 months after the initial treatment. In addition, the levels of MCP-1, RANTES, and granzyme B produced by cultured synovial cells stimulated with TNF-alpha were measured. A significant decrease in serum MCP-1 levels was observed at 3 and 6 months after initial treatment with etanercept. Serum RANTES and granzyme B levels did not show significant changes. TNF-alpha induced MCP-1, RANTES, and granzyme B production in cultured synovial cells from RA patients. Serum MCP-1 levels were significantly correlated with the disease activity scores of 28 joints combined with CRP (DAS28-CRP), indicating the role of MCP-1 in the pathogenesis of rheumatoid inflammation. This study demonstrated that a reduction of MCP-1 production in RA patients was a newly determined effect of etanercept. Another cascade not associated with TNF-alpha may induce granzyme B and RANTES production in RA patients.

Abstract
In human blood, 1% to 5% of lymphocytes are gammadelta T cells; they mostly express the gammadelta T-cell receptor (TCR)Vgamma9, recognize nonpeptide phosphoantigens (PAgs) produced by microbes and tumor cells, and mediate different modes of lytic activities directed against tumor target cells. Antibody-dependent cell-mediated cytotoxicity (ADCC) mediated by cytolytic lymphoid cells is essential for the clinical activity of anticancer monoclonal antibodies (mAbs), but whether PAgs affect ADCC by gammadelta T cells is unknown. Here we report that, in association with the CD20(+)-specific mAb rituximab (RTX), the synthetic PAg bromohydrin pyrophosphate (BrHPP) increased TCRVgamma9(+) cell binding to CD20(+) lymphoma cells in vitro. This combination activated phospho-ZAP70 and phospho-ERK1/2 signaling in TCRVgamma9(+) cells and strongly enhanced their ADCC activity. We obtained similar results with BrHPP in the context of the mAbs alemtuzumab and trastuzumab. Furthermore, BrHPP enhanced RTX-mediated depletion of CD20(+) cells in vitro from peripheral blood mononuclear cells of healthy subjects and enhanced ADCC by gammadelta T cells from patients with chronic lymphocytic leukemia. In cynomolgus macaques, a regimen combining RTX, BrHPP, and IL2 activated TCRVgamma9(+) lymphocytes and enhanced B-cell depletion from blood and lymph nodes. Thus, the combination with BrHPP PAg is able to improve the efficacy of cancer immunotherapy by therapeutic mAbs.

Abstract
OBJECTIVE To investigate the role of perforin-mediated cell apoptosis in murine models of immune-mediated bone marrow (BM) failure. MATERIALS AND METHODS We compared C57BL/6J (B6) mice carrying a perforin gene deletion (Prf(-/-)) with wild-type (WT) controls for cellular composition in lymphohematopoietic tissues. Lymph node (LN) cells from Prf(-/-) mice were coincubated with BM cells from B10-H2(b)/LilMcdJ (C.B10) mice in an apoptosis assay in vitro. We then infused Prf(-/-) and WT B6 LN cells into sublethally irradiated C.B10 and CByB6F1 recipients with mismatches at the minor and major histocompatibility loci, respectively, in order to induce BM failure. Cellular composition was analyzed by flow cytometry. RESULTS Prf(-/-) mice showed normal lymphoid cell composition, but Prf(-/-) LN cells had reduced ability to induce C.B10 BM cell apoptosis in vitro. Infusion of 5 to 10 x 10(6) Prf(-/-) LN cells produced obvious BM failure in C.B10 and CByB6F1 recipients; pancytopenia and BM hypocellularity were only slightly less severe than those caused by infusion of 5 x 10(6) WT B6 LN cells. Infused Prf(-/-) LN cells showed less T-cell expansion, normal T-cell activation, and higher proportions of T cells expressing gamma-interferon, tissue necrosis factor-alpha, and Fas ligand CD178, in comparison to infused WT B6 LN cells. Fas expression was equally high in residual BM cells in recipient of both Prf(-/-) and B6 LN cells. CONCLUSION Perforin deficiency alters T-cell expansion but upregulates T-cell Fas ligand expression. Perforin-mediated cell death appears to play a minor role in mouse models of immune-mediated BM failure.

Abstract
Fas/FasL-mediated apoptosis is involved acute pancreatitis-associated liver injury. It up-regulates proapoptotic pathways in the liver and promotes hepatocytic injury as well as hepatocytic apoptosis during acute pancreatitis. The signal of the production of FasL and the expression of FasL were up-regulated in kupffer cells during acute pancreatitis. Then, FasL activates Fas-associated death domain (FADD) and unmasks its death effector domain (DED) followed by subsequent activation of the Caspase cascade and downstream effector Caspases, ultimately resulting in DNA cleavage and hepatocytic apoptosis. This review aimed to elucidate the construction, distribution and function of Fas/FasL, and to highlight mechanism of acute pancreatitis-associated liver injury mediated by Fas/FasL.
