Abstract
Bacterial genotoxins damage host cells by targeting their chromosomal DNA. In the present study, we demonstrate that a genotoxin of Salmonella Typhi, typhoid toxin, triggers the senescence-associated secretory phenotype (SASP) by damaging mitochondrial DNA. The actions of typhoid toxin disrupt mitochondrial DNA integrity, leading to mitochondrial dysfunction and disturbance of redox homeostasis. Consequently, it facilitates the release of damaged mitochondrial DNA into the cytosol, activating type I interferon via the cGAS-STING pathway. We also reveal that the GCN2-mediated integrated stress response plays a role in the upregulation of inflammatory components depending on the STING signaling axis. These SASP factors can propagate the senescence effect on T cells, leading to senescence in these cells. These findings provide insights into how a bacterial genotoxin targets mitochondria to trigger a proinflammatory SASP, highlighting a potential therapeutic target for an anti-toxin intervention.

Abstract
The formation of germinal centers (GCs) is crucial for humoral immunity and vaccine efficacy. Constant stimulation through microbiota drives the formation of constitutive GCs in Peyer's patches (PPs), which generate B cells that produce antibodies against gut antigens derived from commensal bacteria and infectious pathogens. However, the molecular mechanism that regulates this persistent process is poorly understood. We report that Ewing Sarcoma Breakpoint Region 1 (EWSR1) is a brake to constitutive GC generation and immunoglobulin G (IgG) production in PPs, vaccination-induced GC formation, and IgG responses. Mechanistically, EWSR1 suppresses Bcl6 upregulation after antigen encounter, thereby negatively regulating induced GC B cell generation and IgG production. We further showed that tumor necrosis factor receptor-associated factor (TRAF) 3 serves as a negative regulator of EWSR1. These results established that the TRAF3-EWSR1 signaling axis acts as a checkpoint for Bcl6 expression and GC responses, indicating that this axis is a therapeutic target to tune GC responses and humoral immunity in infectious diseases.

Abstract
CD8+ T cells are central mediators of immune responses against infections and cancer. Here we identified Dapl1 as a crucial regulator of CD8+ T cell responses to cancer and infections. Dapl1 deficiency promotes the expansion of tumour-infiltrating effector memory-like CD8+ T cells and prevents their functional exhaustion, coupled with increased antitumour immunity and improved efficacy of adoptive T cell therapy. Dapl1 controls activation of NFATc2, a transcription factor required for the effector function of CD8+ T cells. Although NFATc2 mediates induction of the immune checkpoint receptor Tim3, competent NFATc2 activation prevents functional exhaustion of CD8+ T cells. Interestingly, exhausted CD8+ T cells display attenuated NFATc2 activation due to Tim3-mediated feedback inhibition; Dapl1 deletion rescues NFATc2 activation and thereby prevents dysfunction of exhausted CD8+ T cells in chronic infection and cancer. These findings establish Dapl1 as a crucial regulator of CD8+ T cell immunity and a potential target for cancer immunotherapy.

Abstract
Dysregulation of pericellular proteolysis is strongly implicated in cancer metastasis through alteration of cell invasion and the microenvironment. Matriptase-2 (MT-2) is a membrane-anchored serine protease which can suppress prostate cancer (PCa) cell invasion. In this study, we showed that MT-2 was down-regulated in PCa and could suppress PCa cell motility, tumor growth, and metastasis. Using microarray and biochemical analysis, we found that MT-2 shifted TGF-β action towards its tumor suppressor function by repressing epithelial-to-mesenchymal transition (EMT) and promoting Smad2 phosphorylation and nuclear accumulation to upregulate two TGF-β1 downstream effectors (p21 and PAI-1), culminating in hindrance of PCa cell motility and malignant growth. Mechanistically, MT-2 could dramatically up-regulate the expression of nuclear receptor NR4A3 via iron metabolism in PCa cells. MT-2-induced NR4A3 further coactivated Smad2 to activate p21 and PAI-1 expression. In addition, NR4A3 functioned as a suppressor of PCa and mediated MT-2 signaling to inhibit PCa tumorigenesis and metastasis. These results together indicate that NR4A3 sustains MT-2 signaling to suppress PCa cell invasion, tumor growth, and metastasis, and serves as a contextual factor for the TGF-β/Smad2 signaling pathway in favor of tumor suppression via promoting p21 and PAI-1 expression.

Abstract
B-cell-activating factor (BAFF) mediates B-cell survival and, when deregulated, contributes to autoimmune diseases and B-cell malignancies. The mechanism connecting BAFF receptor (BAFFR) signal to downstream pathways and pathophysiological functions is not well understood. Here we identified DYRK1a as a kinase that responds to BAFF stimulation and mediates BAFF-induced B-cell survival. B-cell-specific DYRK1a deficiency causes peripheral B-cell reduction and ameliorates autoimmunity in a mouse model of lupus. An unbiased screen identified DYRK1a as a protein that interacts with TRAF3, a ubiquitin ligase component mediating degradation of the noncanonical nuclear factor (NF)-κB-inducing kinase (NIK). DYRK1a phosphorylates TRAF3 at serine-29 to interfere with its function in mediating NIK degradation, thereby facilitating BAFF-induced NIK accumulation and noncanonical NF-κB activation. Interestingly, B-cell acute lymphoblastic leukemia (B-ALL) cells express high levels of BAFFR and respond to BAFF for noncanonical NF-κB activation and survival in a DYRK1a-dependent manner. Furthermore, DYRK1a promotes a mouse model of B-ALL through activation of the noncanonical NF-κB pathway. These results establish DYRK1a as a critical BAFFR signaling mediator and provide novel insight into B-ALL pathogenesis.

Abstract
Microglia have been implicated in neuroinflammatory diseases, including multiple sclerosis and its animal model experimental autoimmune encephalomyelitis (EAE). We demonstrate that microglia mediate EAE disease progression via a mechanism relying on the noncanonical nuclear factor kB (NF-κB) pathway. Microglia-specific deletion of the noncanonical NF-κB-inducing kinase (NIK) impairs EAE disease progression. Although microglial NIK is dispensable for the initial phase of T cell infiltration into the central nervous system (CNS) and EAE disease onset, it is critical for the subsequent CNS recruitment of inflammatory T cells and monocytes. Our data suggest that following their initial CNS infiltration, T cells activate the microglial noncanonical NF-κB pathway, which synergizes with the T cell-derived cytokine granulocyte-macrophage colony-stimulating factor to induce expression of chemokines involved in the second-wave of T cell recruitment and disease progression. These findings highlight a mechanism of microglial function that is dependent on NIK signaling and required for EAE disease progression.

Abstract
Generation and maintenance of antigen-specific effector and memory T cells are central events in immune responses against infections. We show that TNF receptor-associated factor 2 (TRAF2) maintains a survival signaling axis in effector and memory CD8 T cells required for immune responses against infections. This signaling axis involves activation of Tpl2 and its downstream kinase ERK by NF-κB-inducing kinase (NIK) and degradation of the proapoptotic factor Bim. NIK mediates Tpl2 activation by stimulating the phosphorylation and degradation of the Tpl2 inhibitor p105. Interestingly, while NIK is required for Tpl2-ERK signaling under normal conditions, uncontrolled NIK activation due to loss of its negative regulator, TRAF2, causes constitutive degradation of p105 and Tpl2, leading to severe defects in ERK activation and effector/memory CD8 T cell survival. Thus, TRAF2 controls a previously unappreciated signaling axis mediating effector/memory CD8 T cell survival and protective immunity.

Abstract
Current clinical trials of combined EGFR-tyrosine kinase inhibitors (TKI) and immune checkpoint blockade (ICB) therapies show no additional effect. This raises questions regarding whether EGFR-TKIs attenuate ICB-enhanced CD8+ T lymphocyte function. Here we show that the EGFR-TKI afatinib suppresses CD8+ T lymphocyte proliferation, and we identify CAD, a key enzyme of de novo pyrimidine biosynthesis, to be a novel afatinib target. Afatinib reduced tumor-infiltrating lymphocyte numbers in Lewis lung carcinoma (LLC)-bearing mice. Early afatinib treatment inhibited CD8+ T lymphocyte proliferation in patients with non-small cell lung cancer, but their proliferation unexpectedly rebounded following long-term treatment. This suggests a transient immunomodulatory effect of afatinib on CD8+ T lymphocytes. Sequential treatment of afatinib with anti-PD1 immunotherapy substantially enhanced therapeutic efficacy in MC38 and LLC-bearing mice, while simultaneous combination therapy showed only marginal improvement over each single treatment. These results suggest that afatinib can suppress CD8+ T lymphocyte proliferation by targeting CAD, proposing a timing window for combined therapy that may prevent the dampening of ICB efficacy by EGFR-TKIs. SIGNIFICANCE: This study elucidates a mechanism of afatinib-mediated immunosuppression and provides new insights into treatment timing for combined targeted therapy and immunotherapy.

Abstract
Metabolic fitness of T cells is crucial for immune responses against infections and tumorigenesis. Both the T cell receptor (TCR) signal and environmental cues contribute to the induction of T cell metabolic reprogramming, but the underlying mechanism is incompletely understood. Here, we identified the E3 ubiquitin ligase Peli1 as an important regulator of T cell metabolism and antitumor immunity. Peli1 ablation profoundly promotes tumor rejection, associated with increased tumor-infiltrating CD4 and CD8 T cells. The Peli1-deficient T cells display markedly stronger metabolic activities, particularly glycolysis, than wild-type T cells. Peli1 controls the activation of a metabolic kinase, mTORC1, stimulated by both the TCR signal and growth factors, and this function of Peli1 is mediated through regulation of the mTORC1-inhibitory proteins, TSC1 and TSC2. Peli1 mediates non-degradative ubiquitination of TSC1, thereby promoting TSC1-TSC2 dimerization and TSC2 stabilization. These results establish Peli1 as a novel regulator of mTORC1 and downstream mTORC1-mediated actions on T cell metabolism and antitumor immunity.

Abstract
BACKGROUND & AIMS Intestinal epithelial cells (IECs) regulate intestinal immune cells, particularly development of T-helper 17 (Th17) cells. Deregulation of this process leads to intestinal inflammation and tumorigenesis, via unknown mechanisms. TANK-binding kinase 1 (TBK1) is expressed by IECs and cells in the innate immune system. We studied the functions of TBK1 in the intestinal immune response and tumorigenesis in mice. METHODS We performed studies of wild-type mice, mice with conditional disruption of Tbk1 (Tbk1IEC-KO), Tbk1IEC-KO mice crossed with ApcMin/+ mice, and Mt-/- mice crossed with ApcMin/+ mice. Some mice were given intraperitoneal injections of a neutralizing antibody against interleukin 17 (IL17) or IL1β. Intestine tissues were collected from mice and analyzed by histology, for numbers of adenomas and Th17 cells, and expression of inflammatory cytokines by real-time PCR. IECs were isolated from wild-type and Tbk1IEC-KO mice, stimulated with lipopolysaccharide, co-cultured for with bone marrow-derived macrophages, and analyzed by RNA sequencing and biochemical analyses. RESULTS Compared to ApcMin/+Tbk1WT mice, ApcMin/+Tbk1IEC-KO mice had significant increases in number and size of intestinal polyps, and significantly more Th17 cells in lamina propria. Administration of an antibody against IL17 reduced the number of intestinal polyps in ApcMin/+Tbk1IEC-KO mice to that observed in ApcMin/+Tbk1WT mice. In culture, TBK1-deficient IECs promoted expression of IL1β by macrophages, which induced differentiation of naïve CD4+ T cells into Th17 cells. RNA sequencing analysis revealed that the TBK1-deficient IECs had increased expression of metallothionein 1 (MT1), an immune regulator that promotes intestinal inflammation. Intestine tissues from ApcMin/+Mt-/- mice had significant fewer Th17 cells than ApcMin/+Mt+/+ mice, and a significantly lower number of polyps. Analyses of colorectal tumors in the Cancer Genome Atlas found colorectal tumors with high levels of MT1 and IL17 mRNAs to be associated with reduced survival times of patients. CONCLUSIONS Expression of TBK1 by IECs suppresses expression of MT1 and prevents expression of IL1β by macrophages and differentiation of Th17 cells, to prevent inflammation and tumorigenesis. Strategies to block this pathway might be developed for colorectal tumorigenesis.

Abstract
The kinase TBK1 responds to microbial stimuli and mediates type I interferon (IFN-I) induction. We show that TBK1 is also a central mediator of growth factor signaling; this function relies on a specific adaptor, TBK-binding protein 1 (TBKBP1). TBKBP1 recruits TBK1 to PKCθ via a scaffold protein, Card10, which allows PKCθ to phosphorylate TBK1 at serine-716, a crucial step for TBK1 activation by growth factors but not by innate immune stimuli. While the TBK1/TBKBP1 signaling axis is dispensable for IFN-I induction, it mediates mTORC1 activation and oncogenesis. Lung epithelial cell-conditional deletion of either TBK1 or TBKBP1 inhibits tumorigenesis in a mouse model of lung cancer. In addition to promoting tumor growth, the TBK1/TBKBP1 axis facilitates tumor-mediated immunosuppression by a mechanism involving induction of the checkpoint molecule PD-L1 and stimulation of glycolysis. These findings suggest a PKCθ-TBKBP1-TBK1 growth factor signaling axis mediating both tumor growth and immunosuppression.

Abstract
BACKGROUND Liver regeneration is dependent on the proliferation of hepatocytes. Hepatic progenitor cells are intra-hepatic precursor cells capable of differentiating into hepatocytes or biliary cells. Although liver progenitor cell proliferation during the regenerative process has been observed in animal models of severe liver injury, it has never been observed in vivo in humans because it is unethical to take multiple biopsy specimens for the purpose of studying the proliferation of liver progenitor cells and the roles they play in liver regeneration. Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a staged procedure for inducing remnant liver hypertrophy so that major hepatectomy can be performed safely. This staged procedure allows for liver biopsy specimens to be taken before and after the liver begins to regenerate. CASE PRESENTATION The liver progenitor cell proliferation is observed in a patient undergoing ALPPS for a metastatic hepatic tumour. Liver biopsy is acquired before and after ALPPS for the calculation of average number of liver progenitor cell under high magnification examination by stain of immunomarkers. This is the first in vivo evidence of growing liver progenitor cells demonstrated in a regenerating human liver.

Abstract
Dysregulation of pericellular proteolysis is often required for tumor invasion and cancer progression. It has been shown that down-regulation of hepatocyte growth factor activator inhibitor-2 (HAI-2) results in activation of matriptase (a membrane-anchored serine protease), human prostate cancer cell motility and tumor growth. In this study, we further characterized if HAI-2 was a cognate inhibitor for matriptase and identified which Kunitz domain of HAI-2 was required for inhibiting matriptase and human prostate cancer cell motility. Our results show that HAI-2 overexpression suppressed matriptase-induced prostate cancer cell motility. We demonstrate that HAI-2 interacts with matriptase on cell surface and inhibits matriptase proteolytic activity. Moreover, cellular HAI-2 harnesses its Kunitz domain 1 (KD1) to inhibit matriptase activation and prostate cancer cell motility although recombinant KD1 and KD2 of HAI-2 both show an inhibitory activity and interaction with matriptase protease domain. The results together indicate that HAI-2 is a cognate inhibitor of matriptase, and KD1 of HAI-2 plays a major role in the inhibition of cellular matritptase activation as well as human prostate cancer invasion.

Abstract
Abstract
Chronic inflammation plays an important role in the early development and progression of cancer. Cyclooxygenases-2 (COX-2) is a key rate-limiting enzyme which regulates of inflammation-producing prostaglandins. Several studies have shown that COX-2 is found with overexpression in human cancers (colon, breast, lung, prostate cancers, etc), and implicated in cancer cell invasion. Moreover, high COX-2 expression has been correlated with prostate cancer metastasis. However, the molecular mechanism that COX-2 promotes prostate cancer cell invasion is still unclear. In this study, we established a PC-3 cell invasion progression model (parental and M2I2 PC-3 cells) and found out that several inflammation-associated proteins, COX-2, p-JNK and IL-1β were up-regulated in M2I2 PC-3 cells. Therefore, we purposed that if COX-2 signaling plays a role in prostate cancer cell invasion and the involvement of matriptase in COX-2 signaling-induced cancer cell invasion. The results showed that COX-2 inhibitors (celebrex and sulindac sulfide) could suppress prostate cancer PC3 cell invasion and inhibited matriptase expression and activation. A COX-2 product PGE2 could induce matriptase activation and prostate cancer cell invasion. COX-2 overexpression also could up-regulate matriptase and enhance the cancer cell invasion, while COX-2 silencing antagonized both matriptase activation and cell invasion. Thus, our results indicate that COX-2 signaling can promote prostate cancer cell invasion, at least in part via up-regulating matriptase.

Abstract
Ketamine, a dissociative anesthetic, is misused and abused worldwide as an illegal recreational drug. In addition to its neuropathic toxicity, ketamine abuse has numerous effects, including renal failure; however, the underlying mechanism is poorly understood. The process called epithelial phenotypic changes (EPCs) causes the loss of cell-cell adhesion and cell polarity in renal diseases, as well as the acquisition of migratory and invasive properties. Madin-Darby canine kidney cells, an in vitro cell model, were subjected to experimental manipulation to investigate whether ketamine could promote EPCs. Our data showed that ketamine dramatically decreased transepithelial electrical resistance and increased paracellular permeability and junction disruption, which were coupled to decreased levels of apical junctional proteins (ZO-1, occludin, and E-cadherin). Consistent with the downregulation of epithelial markers, the mesenchymal markers N-cadherin, fibronectin, and vimentin were markedly upregulated following ketamine stimulation. Of the E-cadherin repressor complexes tested, the mRNA levels of Snail, Slug, Twist, and ZEB1 were elevated. Moreover, ketamine significantly enhanced migration and invasion. Ketamine-mediated changes were at least partly caused by the inhibition of GSK-3β activity through Ser-9 phosphorylation by the PI3K/Akt pathway. Inhibiting PI3K/Akt with LY294002 reactivated GSK-3β and suppressed ketamine-enhanced permeability, EPCs, and motility. These findings were recapitulated by the inactivation of GSK-3β using the inhibitor 3F8. Taken together, these results provide evidence that ketamine induces renal distal tubular EPCs through the downregulation of several junction proteins, the upregulation of mesenchymal markers, the activation of Akt, and the inactivation of GSK-3β.

Abstract
Dysregulation of androgen signaling and pericellular proteolysis is necessary for prostate cancer progression, but the links between them are still obscure. In this study, we show how the membrane-anchored serine protease TMPRSS2 stimulates a proteolytic cascade that mediates androgen-induced prostate cancer cell invasion, tumor growth, and metastasis. We found that matriptase serves as a substrate for TMPRSS2 in mediating this proinvasive action of androgens in prostate cancer. Further, we determined that higher levels of TMPRSS2 expression correlate with higher levels of matriptase activation in prostate cancer tissues. Lastly, we found that the ability of TMPRSS2 to promote prostate cancer tumor growth and metastasis was associated with increased matriptase activation and enhanced degradation of extracellular matrix nidogen-1 and laminin β1 in tumor xenografts. In summary, our results establish that TMPRSS2 promotes the growth, invasion, and metastasis of prostate cancer cells via matriptase activation and extracellular matrix disruption, with implications to target these two proteases as a strategy to treat prostate cancer.

Abstract
UNLABELLED Osteoarthritis (OA), the most common type of arthritis, is a degenerative joint disease. Oxidative stress is well known to play important roles in cartilage degradation and pathogenesis of OA. The intra-articular injection of hyaluronic acid (IAHA) is accepted as an effective clinical therapy for OA, but we do not yet fully understand the mechanisms underlying the effects of HA on OA chondrocytes under oxidative stress. Here, we show for the first time that IAHA significantly reduces the synovial fluid levels of hydrogen peroxide (H2O2) and superoxide (O2(-)) in patients with knee OA. We also demonstrate that HA suppresses H2O2-induced cell death in human OA chondrocytes. Proteomic approaches (2-DE combined with mass spectrometry) allowed us to identify 13 protein spots corresponding to 12 non-redundant proteins as HA-regulated proteins in OA chondrocytes under oxidative stress. The expression levels of three putative HA-regulated proteins (TALDO, ANXA1 and EF2) in control, H2O2-, HA- and HA/H2O2-treated OA chondrocytes were verified by Western blotting and the results indeed support the notion that HA acts in anti-oxidation, anti-apoptosis, and the promotion of cell survival. Our results collectively demonstrate the utility of proteomic approaches and provide new insights into the chondroprotective effects of HA on OA. BIOLOGICAL SIGNIFICANCE In the present study, we show for the first time that IAHA reduces the levels of H2O2 and O2(-) in synovial fluids from OA patients. We used primary cultured human OA chondrocytes as a model, treated cells with H2O2 to partly mimic their physiological conditions under oxidative stress, and examined the protection effects of HA. The proteomic approach allowed us to identify candidate proteins regulated by H2O2 and/or HA in OA chondrocytes. We found that proteins functioning in stress responses, apoptosis and protein synthesis were consistently regulated by HA in chondrocytes under oxidative stress. These novel results contribute to our understanding of the molecular mechanisms underlying HA-mediated chondroprotection.

Abstract
Curcumin has been shown to possess potent chemopreventive and antitumor effects on prostate cancer. However, the molecular mechanism involved in curcumin's ability to suppress prostate cancer cell invasion, tumor growth, and metastasis is not yet well understood. In this study, we have shown that curcumin can suppress epidermal growth factor (EGF)- stimulated and heregulin-stimulated PC-3 cell invasion, as well as androgen-induced LNCaP cell invasion. Curcumin treatment significantly resulted in reduced matrix metalloproteinase 9 activity and downregulation of cellular matriptase, a membrane-anchored serine protease with oncogenic roles in tumor formation and invasion. Our data further show that curcumin is able to inhibit the induction effects of androgens and EGF on matriptase activation, as well as to reduce the activated levels of matriptase after its overexpression, thus suggesting that curcumin may interrupt diverse signal pathways to block the protease. Furthermore, the reduction of activated matriptase in cells by curcumin was also partly due to curcumin's effect on promoting the shedding of matriptase into an extracellular environment, but not via altering matriptase gene expression. In addition, curcumin significantly suppressed the invasive ability of prostate cancer cells induced by matriptase overexpression. In xenograft model, curcumin not only inhibits prostate cancer tumor growth and metastasis but also downregulates matriptase activity in vivo. Overall, the data indicate that curcumin exhibits a suppressive effect on prostate cancer cell invasion, tumor growth, and metastasis, at least in part via downregulating matriptase function.

Abstract
Curcumin has been shown with potent chemopreventive and antitumor effects on prostate cancer. However, the molecular mechanism how curcumin suppresses prostate cancer cell migration and invasion is not well understood. In this study we showed that curcumin could significantly suppress prostate cancer PC3 cell migration and invasion. Moreover, our data also showed that curcumin was able to suppress EGF- or heregulin-stimulated PC-3 cell invasion, as well as androgen-induced LNCaP cell invasion. Curcumin treatment resulted in not only significant reductions on MMP-9 and MMP-2 activities, but also on activated level of matriptase which is a membrane-bound serine protease and has been proposed to play important roles in tumor invasion and malignancy. Matriptase is synthesized as a full length zymogen, which is rapidly stepped into the maturation process, mature form through a cleavage within the SEA domain to from a latent matriptase. Our data further showed that curcumin can inhibit the latent matriptase formation in the maturation process to affect matriptase activity. Furthermore, the reduction of activated matriptase by curcumin was also partly due to curcumin promoting the shedding of activated matriptase into extracellular environment, but not due to curcumin effect on matriptase gene expression. In addition, we established the stable pools of CWR22Rv1 cells with matriptase overexpression and found that expression of matriptase in CWR22Rv1 cells enhanced their invasive ability. With curcumin treatment, the invasive ability induced by matriptase overexpression was significantly suppressed. In summary, the data indicated that curcumin exhibits a suppressive effect on prostate cancer cell invasion, at least in part by down-regulating matriptase activity.

Abstract
Abstract
Dysregulation of pericellular proteolysis has been strongly involved in tumorigenesis. In this study, we delineated the role of hepatocyte growth factor activator inhibitor-2 (HAI-2) in prostate cancer cell invasion and tumorigenicity within a human prostate cancer progression model (103E, N1, and N2 cells). This model was newly established by a serial of intraprostatic propagation of a human prostate cancer 103E cell line and isolation of the metastatic cells from nearby lymph nodes. The invasion capability of these cells was gradually increased after the serial isolations (103E<N1 <N2). In this series of cells, the expression of HAI-2 was significantly decreased during the progression. Following the course of orthotopic tumor growth in mice, the expression level and activity of a HAI-2 target, matriptase, increased while the HAI-2 protein level decreased. Restoration of HAI-2 expression in N2 cells down-regulated the matriptase activity and cell proliferation, thus decreased the tumorigenicity. These results show that during the progression of human prostate cancer, matriptase was primarily controlled by HAI-2 expression. The imbalance in HAI-2 and matriptase expression led to matriptase activation, therefore increased cell invasion and tumorigenicity.

Abstract
Abstract
Dysregulation of proteolysis on cell surface has been strongly implicated in cancer cell migration and invasion. In this study, we delineated the role of hepatocyte growth factor activator inhibitor-2 (HAI-2) in prostate cancer cell migration and invasion within a human prostate cancer progression model, established by a serial of intraprostatic injections of prostate cancer cells and isolation of the invasive cells from nearby lymph nodes. The invasion capability of these cells was increased after the serial isolations. Interestingly, the expression of HAI-2 but not HAI-1 was dramatically decreased following the progression and concurrent with an increase of activated matriptase. Overexpression of HAI-2 reduced prostate cancer cell migration and invasion, at least in part due to its inhibitory role in matriptase. Following the orthotopic tumor growth in mice, the level of matriptase was increased while HAI-2 protein level was decreased. These results indicated that during the progression of human prostate cancer, HAI-2 expression was reduced, leading to constitutive matriptase activation, increased cell migration and invasion. Thus, HAI-2 exerted an inhibitory role in prostate cancer progression partly through inhibiting matripase activity. Imbalance between HAI-2 and matriptase may result in prostate tumor progression.

Abstract
Deregulation of both ErbB-2 signaling and matriptase activity has been associated with human prostate cancer (PCa) progression. In this communication, we investigated the roles of both ErbB-2 signaling in matriptase zymogen activation and matriptase in ErbB-2-induced PCa malignancy. In a human PCa cell progression model, we observed that advanced PCa C-81 LNCaP cells exhibited an aggressive phenotype with increased cell migration and invasion capacity; these cells concurrently showed both enhanced ErbB-2 phosphorylation and increased matriptase zymogen activation compared with parental C-33 LNCaP cells. Moreover, ErbB2 activation, both ligand-dependent (eg, epidermal growth factor treatment) and ligand-independent (eg, overexpression), was able to induce matriptase zymogen activation in this cell line. Inhibition of ErbB-2 activity by either the specific inhibitor, AG825, in epidermal growth factor-treated C-33 LNCaP cells or ErbB-2 knockdown in C-81 LNCaP cells, reduced matriptase activation. These observations were confirmed by similar studies using both DU145 and PC3 cells. Together, these data suggest that ErbB-2 signaling plays an important role in matriptase zymogen activation. ErbB-2-enhanced matriptase activation was suppressed by a phosphatidylinositol 3-kinase inhibitor (ie, LY294002) but not by a MEK inhibitor (ie, PD98059). Suppression of matriptase expression by small hairpin RNA knockdown in ErbB-2-overexpressing LNCaP cells dramatically suppressed cancer cell invasion. In summary, our data indicate that ErbB-2 signaling via the phosphatidylinositol 3-kinase pathway results in up-regulated matriptase zymogen activity, which contributes to PCa cell invasion.

Abstract
60 patients (except parturients) suffering from shivering after receiving epidural anesthesia were randomly divided into 2 equal groups. In order to evaluate the effect of Tramadol on the shivering, i.v. Tramadol (1 mg/Kg), in contrast to distilled water (20 ml) for the control group, was administered to the patients in the experimental group. We compared the arrest time between the two groups in addition to systolic blood pressure, diastolic blood pressure, heart rate, arterial O2 saturation, respiratory rate and body surface temperature. Furthermore, the degree of shivering was also compared sequentially. The systolic pressure of the control group declined significantly in the first 30 minutes (P < 0.05). The other data, including the diastolic pressure, heart rate, arterial O2 saturation, respiratory rate and body surface temperature, showed no significant difference (P > 0.05). The arrest time in the experimental group was 179 +/- 71.25 seconds in contrast to 2790 +/- 440.23 seconds in the control group, a large significant difference (P < 0.001). 10% of the patients in the experimental group experienced nausea or vomiting and 6.67% of the patients showed sedation which did not disturb consciousness level of psychomotor status. Since the exact mechanism of shivering during epidural anesthesia is not established, we sincerely hope more information about the effect to Tramadol on shivering can be uncovered.

Abstract
The sedating effect and influence of walkman music on 120 patients, that were randomly divided into a music and non-music group, who had received epidural anesthesia were investigated. It was found that significantly fewer patients in the music group felt anxious during surgery (P = 0.049). Meanwhile, heart rate and mean arterial pressure of the non-music group remained at a higher level, resulting in higher heart loading. Furthermore, patients listening to music had a significantly smaller need of sedatives (P = 0.001). With the purpose of reducing the consumption of sedatives, and offering a better anesthetic environment, we recommend the use of music during regional anesthesia.
