Abstract
INTRODUCTION Inflammation is important in the pathogenesis of atherosclerosis. Elevated interleukin-6 (IL-6) is associated with cardiovascular events and also predicts mortality in individuals with CKD. Our goal was to determine the association between IL-6, FGF23, and high-sensitivity C-reactive protein (hsCRP) on coronary artery calcification (CAC) progression and mortality in incident dialysis patients without prior coronary events. METHODS A prospective cohort of incident adult dialysis participants had CAC measured by ECG-triggered multislice CT scans at baseline and at least 12 months later. Lipids, mineral metabolism markers, FGF23, and inflammatory markers, such as IL-6 and hsCRP, were measured at the baseline visit. RESULTS Participants in the high IL-6 tertile had the highest baseline CAC score (133.25 [10.35-466.15]) compared to the low (0.25 [0-212.2]) and intermediate (29.55 [0-182.85]) tertiles. Almost half of the participants with high IL-6 (15 of 32 [46.9%]) experienced progression of CAC compared to participants with low (8 of 32 [25%]) and intermediate (9 of 32 [28.1%]) (p = 0.05) IL-6 levels. Each log increase in IL-6 was associated with increase in death (hazard ratio 2.2, 95% CI: 1.2-3.8; p = 0.01). After adjusting for smoking, age, gender, race, diabetes, phosphate, and baseline calcium score, IL-6 (log) was associated with 2.2 times (95% CI: 1.1-4.6; p = 0.03) increase in death. CONCLUSION IL-6 is associated with progression of CAC and mortality in incident dialysis patients.

Abstract
Recent studies have shown that C-reactive protein (CRP) participates in multiple types of cancer development. Here, the aim of this study was to investigate the role of CRP in tongue squamous cell carcinoma (TSCC) chemoresistance. Immunohistochemical staining showed that CRP expression was upregulated in TSCC tissues from cisplatin-resistant patients compared with that in cisplatin-sensitive TSCC samples. The CRP expression level was positively correlated with that of the drug-resistant marker MDR1. Moreover, functional experiments showed that CRP increased cell viability and decreased cisplatin-induced apoptosis. CRP also increased the expression levels of MDR1 and Bcl-2 and decreased the expression level of Bax. Furthermore, CRP decreased the activity of caspase-3. Mechanistically, CRP could bind to Fcγ receptor I (FcγRI, also known as CD64) and activate the AKT/mTOR pathway to inhibit the activation of caspase-3/9, as shown by co-immunoprecipitation (Co-IP) assay and western blotting assays. In addition, CRP promoted tumour growth and decreased cleaved caspase-3/9 expression in BALB/c nude mice. Taken together, our findings indicate that CRP promotes TSCC chemoresistance by inhibiting the activation of caspase-3/9 via the FcγRI/AKT/mTOR pathway. Thus, CRP could potentially be considered as a therapeutic target for reducing TSCC chemoresistance.

Abstract
Pentraxin 3 (PTX3) is a glycoprotein belonging to the humoral arm of innate immunity that participates in the body’s defence mechanisms against infectious diseases. It has recently been defined as a multifunctional protein, given its involvement in numerous physiological and pathological processes, as well as in the pathogenesis of age-related diseases such as osteoporosis. Based on this evidence, the aim of our study was to investigate the possible role of PTX3 in both the osteoblastic differentiation and calcification process: to this end, primary osteoblast cultures from control and osteoporotic patients were incubated with human recombinant PTX3 (hrPTX3) for 72 h. Standard osteinduction treatment, consisting of β-glycerophosphate, dexamethasone and ascorbic acid, was used as control. Our results showed that treatment with hrPTX3, as well as with the osteogenic cocktail, induced cell differentiation towards the osteoblastic lineage. We also observed that the treatment not only promoted an increase in cell proliferation, but also the formation of calcification-like structures, especially in primary cultures from osteoporotic patients. In conclusion, the results reported here suggest the involvement of PTX3 in osteogenic differentiation, highlighting its osteoinductive capacity, like the standard osteoinduction treatment. Therefore, this study opens new and exciting perspectives about the possible role of PTX3 as biomarker and therapeutic agent for osteoporosis.

Abstract
Background and Objectives: Ischaemic stroke (IS) is the leading cause of death and disability worldwide. All stages of cerebral ischaemia, but especially acute phase, are associated with inflammatory response. Recent studies showed that neutrophil-to-lymphocyte ratio (NLR) and lymphocyte-to-monocyte ratio (LMR) may be used to assess inflammation in IS. To test whether there is a relationship between these parameters and type of stroke treatment, we analysed NLR and LMR in IS patients treated with three different modalities. Materials and Methods: The study included 58 adults with acute IS. A total of 28 patients received intravenous thrombolysis. In another 10 patients, the thrombolytic therapy was followed by thrombectomy and 20 patients did not undergo causal treatment. Blood samples were obtained within 24 h of the stroke diagnosis to calculate NLR and LMR. Next, NLR and LMR of the study subgroups were compared. Results: Our study revealed that NLR was significantly higher in patients treated with thrombectomy following thrombolysis, compared to no causal treatment. Statistical analysis demonstrated that patients with high National Institutes of Health Stroke Scale (NIHSS) scores presented higher NLR than in those with low NIHSS scores. Additionally, patients with high-sensitivity C-reactive protein (hs-CRP) ≥ 3 mg/L presented with significantly higher NLR and significantly lower LMR than the group of patients with lower hs-CRP (<3 mg/L). Conclusions: The main finding of this pilot study was that NLR in IS patients treated using thrombectomy following thrombolysis was markedly higher than that in other treatment groups, which was associated with increased severity of the disease in these patients. Therefore, patients with higher NLR may be expected to have more severe stroke. The link between stroke severity and NLR deserves further study.

Abstract
Cutaneous melanoma is one of the most aggressive cancers characterized by a high plasticity, a propensity for metastasis, and drug resistance. Melanomas are composed of phenotypically diverse subpopulations of tumor cells with heterogeneous molecular profiles that reflect intrinsic invasive abilities. In an attempt to identify novel factors of the melanoma invasive cell state, we previously investigated the nature of the invasive secretome by using a comparative proteomic approach. Here, we have extended this analysis to show that PTX3, an acute phase inflammatory glycoprotein, is one such factor secreted by invasive melanoma to promote tumor cell invasiveness. Elevated PTX3 production was observed in the population of MITFlow invasive cells but not in the population of MITFhigh differentiated melanoma cells. Consistently, MITF knockdown increased PTX3 expression in MITFhigh proliferative and poorly invasive cells. High levels of PTX3 were found in tissues and blood of metastatic melanoma patients, and in BRAF inhibitor-resistant melanoma cells displaying a mesenchymal invasive MITFlow phenotype. Genetic silencing of PTX3 in invasive melanoma cells dramatically impaired migration and invasion in vitro and in experimental lung extravasation assay in xenografted mice. In contrast, addition of melanoma-derived or recombinant PTX3, or expression of PTX3 enhanced motility of low migratory cells. Mechanistically, autocrine production of PTX3 by melanoma cells triggered an IKK/NFκB signaling pathway that promotes migration, invasion, and expression of the EMT factor TWIST1. Finally, we found that TLR4 and MYD88 knockdown inhibited PTX3-induced melanoma cell migration, suggesting that PTX3 functions through a TLR4-dependent pathway. Our work reveals that tumor-derived PTX3 contributes to melanoma cell invasion via targetable inflammation-related pathways. In addition to providing new insights into the biology of melanoma invasive behavior, this study underscores the notion that secreted PTX3 represents a potential biomarker and therapeutic target in a subpopulation of MITFlow invasive and/or refractory melanoma.

Abstract
BACKGROUND & AIM The results of studies about the effect of soy products on serum highly sensitive C-reactive protein (hs-CRP) are inconsistent. The aim of this systematic review and meta-analysis of randomized clinical trials (RCTs) was to investigate the effect of soy products intake on serum hs-CRP concentration. METHODS We searched PubMed, EMBASE, Science Direct, ISI Web of Science, Google Scholar and Cochrane Central Register of Controlled Trials up to December 2016 without language restrictions. Random-effect model was used for quantitative data synthesis. RESULTS Thirty-six studies were included in our analyses. A meta-analysis revealed a non-significant reduction in serum hs-CRP concentrations following soy products consumption, -0.19 (mg/L) (95% CI: -0.49 to 0.09; I2 = 95.6%). Subgroup analyses suggested that natural soya products may reduce plasma levels of CRP by -0.18 mg/L (95% CI: -0.28 to -0.08; I2: 11.6) in comparison to other source of isoflavones (soya extracts, supplements). Moreover, the effect was stronger among subjects with baseline hs-CRP concentrations of less than 2.52 mg/L, -0.15 (95% CI: -0.27 to -0.02; I2: 34.6). A meta-regression analysis revealed that dosage of isoflavones seems to be a strong predictor of the effect of soya on serum hs-CRP levels. CONCLUSION Present review of RCTs published up to December 2016 did not provide strong evidence regarding the beneficial effect of soya products consumption on blood hs-CRP concentrations. However, it appears that natural soya products may reduce plasma levels of hs-CRP in comparison to other source of isoflavones. Large and well-designed studies are recommended to confirm this conclusion. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42018069371.

Abstract
Accumulating evidence from clinical and epidemiological studies has highlighted the close correlation between the individual risk of cancer and nervous system diseases. The expression of neuronal pentraxin 2 (NPTX2) is absent in Alzheimer's disease, anxiety, and depression. Herein, we found that NPTX2 mRNA and protein expression was significantly upregulated in colorectal carcinoma (CRC). NPTX2 expression level gradually increased with CRC progression and was closely associated with poor prognosis. In vitro and in vivo studies demonstrated that NPTX2 promoted CRC proliferation and metastasis through the activation of the Wnt/β-catenin signaling pathway. As NPTX2 receptors are absent on CRC cells, NPTX2 was shown to physically interact with frizzled class receptor 6 (FZD6) to promote β-catenin translocation into the cell nucleus, resulting in an increase in the expression of MYC, cyclin D1, snail, and N-cadherin along with a decrease in the expression of E-cadherin. Knockdown of FZD6 expression with a small-interfering RNA almost completely reversed the proliferative effects of NPTX2 on CRC development. In conclusion, NPTX2, a molecule related to nervous system diseases, promotes CRC cell proliferation and metastasis through the activation of the Wnt/β-catenin pathway via direct interaction with FZD6.

Abstract
Restoration of cerebral blood flow (CBF) and upregulation of angiogenesis are crucial for brain repair and functional recovery after cerebral ischaemia. Pentraxin 3 (PTX3) is a key regulator of angiogenesis and is emerging as a promising target for cerebrovascular repair after stroke. Here, we investigated for the first time the role of PTX3 in long-term CBF, angiogenesis, and neuronal viability after ischaemic stroke induced by transient middle cerebral artery occlusion (MCAo). Lack of PTX3 had no effect on early brain damage, but significantly impaired restoration of CBF, 14 and 28 days after MCAo, compared to wild-type (WT) mice. Immunohistochemical analysis revealed that PTX3 KO mice have significantly greater neuronal loss, significantly decreased vessel diameter, vessel proliferation, vascular density, and reactive astrocytes and decreased expression of vascular endothelial growth factor receptor 2 (VEGR2), vascular extracellular matrix (ECM)-proteins (collagen IV, laminin), and integrin-β, in the ipsilateral (stroke) hemisphere compared to WT mice, 28 days after MCAo. Therefore, PTX3 promotes sustained long-term recovery of CBF, angiogenesis, and neuronal viability after cerebral ischaemia. Collectively, these findings demonstrate the potential and clinical relevance of PTX3 as a promising therapeutic target, providing sustained long-term post-stroke neurovascular repair and reducing the loss of neurons. KEY MESSAGES: Pentraxin 3 (PTX3) is a key regulator of angiogenesis and is emerging as a promising target for cerebrovascular repair after stroke.

Abstract
One of the most common inflammatory markers examined in depression is C-reactive protein (CRP). However, the magnitude of the association between CRP and depression when controlling for potentially confounding factors such as age, sex, socio-economic status, body mass index, medication and other substance use, and medical illness, is unclear. Inconsistencies in other methodological practices, such as sample collection, assaying, and data cleaning and transformation, may contribute to variations in results. We aggregate studies that examined the association between CRP and depression in two ways. First, a systematic review summarizes how studies of CRP and depression have reported on methodological issues. Second, a tiered meta-analysis aggregates studies that have adhered to various levels of methodological rigor. Findings from the systematic review indicate a lack of protocol detail provided. The effect between depression and CRP was small, but highly significant across all stages of the meta-analysis (p < 0.01). The effect size in the most methodologically rigorous stage of the meta-analysis, which included studies controlling for age, sex, obesity, medical conditions and substance, medication, or psychosocial factors, was small (r = 0.05). There were also only 26 articles in this stage (13% of studies from the systematic review), suggesting that more studies that consistently account for these confounding factors are needed. Additionally, an a priori quality score of methodological rigor was a significant moderator in this stage of the meta-analysis. The effect size was strikingly attenuated (r = 0.005) and non-significant in studies with higher quality scores. We describe a set of recommended guidelines for future research to consider, including sample collection and assaying procedures, data cleaning and statistical methods, and control variables to assess.

Abstract
The role of adipocytes in cancer microenvironment has gained focus during the recent years. However, the characteristics of the cancer-associated adipocytes (CAA) in human breast cancer tissues and the underlying regulatory mechanism are not clearly understood. We reviewed pathology specimens of breast cancer patients to understand the morphologic characteristics of CAA, and profiled the mRNA and miRNA expression of CAA by using indirect co-culture system in vitro. The CAAs in human breast cancers showed heterogeneous topographic relationship with breast cancer cells within the breast microenvironment. The CAAs exhibited the characteristics of de-differentiation determined by their microscopic appearance and the expression levels of adipogenic markers. Additionally, the 3T3-L1 adipocytes indirectly co-cultured with breast cancer cells showed up-regulation of inflammation-related genes including Il6 and Ptx3. The up-regulation of IL6 in CAA was further observed in human breast cancer tissues. miRNA array of indirectly co-cultured 3T3-L1 cells showed increased expression of mmu-miR-5112 which may target Cpeb1. Cpeb1 is a negative regulator of Il6. The suppressive role of mmu-miR-5112 was confirmed by dual luciferase reporter assay, and mmu-miR-5112-treated adipocytes showed up-regulation of Il6. The transition of adipocytes into more inflammatory CAA resulted in proliferation-promoting effect in ER positive breast cancer cells such as MCF7 and ZR-75-1 but not in ER negative cells. In this study, we have determined the de-differentiated and inflammatory natures of CAA in breast cancer microenvironment. Additionally, we propose a miRNA-based regulatory mechanism underlying the process of acquiring inflammatory phenotypes in CAA.

Abstract
To explore the association among C reactive protein (CRP) level, disease severity and non-sedating antihistamine drug efficacy in patients with chronic spontaneous urticaria.
Methods: A total of 605 patients with chronic spontaneous urticaria from August 2013 to March 2015, diagnosed by dermatologist of Xiangya Hospital according to the guideline, were enrolled in present study. The patients were divided into two groups according to the weekly urticaria activity score (UAS): a response group (more than 50% reduction) and a nonresponse group (less than 50% reduction). T test and Pearson correlation analysis were used to analyze the correlation between the clinical characteristics (such as disease severity, drug efficacy) and CRP in patients with chronic spontaneous urticaria.
Results: The CRP levels were significantly higher in patients with severe chronic spontaneous urticaria as compared to those with moderate chronic spontaneous urticaria (t=-2.715, P<0.01). Meanwhile, after treatment with secondary antihistamine drug, the patients with lower CRP levels showed better responses than those with higher CRP levels [(2.5764±2.5059) and (3.6715±4.7732) mg/dL respectively; t=-2.187, P<0.05].
Conclusion: Serum CRP level before the treatment may be correlated with the severity of chronic spontaneous urticaria and efficacy of treatment.

Abstract
BACKGROUND Elevated levels of C-reactive protein (CRP, determined by a high-sensitivity assay) indicate low-grade inflammation which is implicated in many age-related disorders. Epigenetic studies on CRP might discover molecular mechanisms underlying CRP regulation. We aimed to identify DNA methylation sites related to CRP concentrations in cells and tissues regulating low-grade inflammation. RESULTS Genome-wide DNA methylation was measured in peripheral blood in 1,741 participants of the KORA F4 study using Illumina HumanMethylation450 BeadChip arrays. Four CpG sites (located at BCL3, AQP3, SOCS3, and cg19821297 intergenic at chromosome 19p13.2, P ≤ 1.01E-07) were significantly hypomethylated at high CRP concentrations independent of various confounders including age, sex, BMI, smoking, and white blood cell composition. Findings were not sex-specific. CRP-related top genes were enriched in JAK/STAT pathways (Benjamini-Hochberg corrected P < 0.05). Results were followed-up in three studies using DNA from peripheral blood (EPICOR, n = 503) and adipose tissue (TwinsUK, n = 368) measured as described above and from liver tissue (LMU liver cohort, n = 286) measured by MALDI-TOF mass spectrometry using EpiTYPER. CpG sites at the AQP3 locus (significant p-values in peripheral blood = 1.72E-03 and liver tissue = 1.51E-03) and the SOCS3 locus (p-values in liver < 2.82E-05) were associated with CRP in the validation panels. CONCLUSIONS Epigenetic modifications seem to engage in low-grade inflammation, possibly via JAK/STAT mediated pathways. Results suggest a shared relevance across different tissues at the AQP3 locus and highlight a role of DNA methylation for CRP regulation at the SOCS3 locus.

Abstract
C-reactive protein (CRP) has been suggested to play a role in the pathogenesis of atherosclerosis. Neutrophil respiratory burst and levels of CRP are increased during infection. The increase in the neutrophil respiratory burst may be due to factors that are elevated in infection, such as cytokines, tumor necrosis factor, platelet-activating factor, and CRP. The direct effect of CRP on the release of oxygen radicals by neutrophils is not known. This investigation was made to determine if CRP affects the generation of oxygen radicals by neutrophils and if this effect is blocked by antioxidants. The effect of various concentrations (1 to 200 µg/mL blood) of CRP on the generation of oxygen radicals by neutrophils was measured as luminol-dependent chemiluminescence (chemiluminescent activity) on a luminometer (Auto Lumat LB953, EG & G Berthold, Gaithersburg, MD). The unit of chemiluminescent activity is the relative light unit and was expressed as relative light unit/white blood cell (RLU/WBC). Chemiluminescent activity of blood without CRP was slightly higher than that of buffer with or without CRP. CRP markedly increased the chemiluminescent activity of blood. There was no significant change in the chemiluminescent activity of WBCs with 1 µg/mL of CRP. The chemiluminescent activity increased significantly with higher concentrations of CRP. The percent increases in the chemiluminescent activity with 2, 5, 10, 25, 50, 100 and 200 µg/mL of CRP were 45%, 72%, 50%, 70%, 52%, 67%, and 68% respectively. Antioxidants (superoxide dismutase, catalase, and dimethylthiourea) blocked CRP-induced oxygen radicals by WBCs. These results suggest that CRP increases the generation of oxygen radicals from the WBCs. CRP-induced atherosclerosis may be mediated through generation of oxygen radicals by neutrophils.

Abstract
Recently, a possible relationship between C-Reactive Protein (CRP), a marker of underlying low-grade inflammation, and mood disorders has been proposed by some researchers. The aim of this review is to elucidate the current facts and views about CRP in mood disorders such as Depressive and Bipolar Disorders. Several studies have examined the relationship between affective disorders and CRP, but the majority of the studies in literature have been limited by retrospective, case-controlled study design, and very few studies have examined the relationship between depression and CRP in large study samples. In conclusion, the role of CRP in mood disorders is, to date, intriguing but somewhat unclear. Further prospective studies are needed to introduce the CRP in clinical settings as a marker of affective states and suicidability.

Abstract
PURPOSE Human limbal palisade of Vogt is an ideal model for studying and practicing regenerative medicine due to their accessibility. Nonresolving inflammation is a common manifestation of limbal stem cell deficiency, which is the major cause of corneal blindness, and presents as a threat to the success of transplanted limbal epithelial stem cells. Clinical studies have shown that the efficacy of transplantation of limbal epithelial stem cells can be augmented by transplantation of cryopreserved human amniotic membrane (AM), which exerts anti-inflammatory, antiscarring, and antiangiogenic action to promote wound healing. METHODS Review of published data to determine the molecular action mechanism explaining how AM exerts the aforementioned therapeutic actions. RESULTS From the water-soluble extract of cryopreserved AM, we have biochemically purified one novel matrix component termed heavy chain (HC)-hyaluronan (HA)/pentraxin 3 (PTX3) as the key relevant tissue characteristic responsible for the aforementioned AM's efficacy. Heavy chain-HA is a complex formed by a covalent linkage between HA and HC1 of inter-α-trypsin inhibitor (IαI) by tumor necrosis factor-stimulated gene-6 (TSG-6). This complex may then be tightly associated with PTX3 to form HC-HA/PTX3 complex. Besides exerting an anti-inflammatory, antiscarring, and antiangiogenic effects, HC-HA/PTX3 complex also uniquely maintains limbal niche cells to support the quiescence of limbal epithelial stem cells. CONCLUSIONS We envision that HC-HA/PTX3 purified from AM can be used as a unique substrate to refine ex vivo expansion of limbal epithelial stem cells by maintaining stem cell quiescence, self-renewal and fate decision. Furthermore, it can also be deployed as a platform to launch new therapeutics in regenerative medicine by mitigating nonresolving inflammation and reinforcing the well-being of stem cell niche.

Abstract
Given documented links between individual socioeconomic status (SES) and health, it is likely that-in addition to its impacts on individuals' wallets and bank accounts-the Great Recession also took a toll on individuals' disease and mortality risk. Exploiting a quasi-natural experiment design, this study utilizes nationally representative, longitudinal data from the National Social Life, Health, and Aging Project (NSHAP) (2005-2011) (N = 930) and individual fixed effects models to examine how household-level wealth shocks experienced during the Great Recession relate to changes in biophysiological functioning in older adults. Results indicate that wealth shocks significantly predicted changes in physiological functioning, such that losses in net worth from the pre-to the post-Recession period were associated with increases in systolic blood pressure and C-reactive protein over the six year period. Further, while the association between wealth shocks and changes in blood pressure was unattenuated with the inclusion of other indicators of SES, psychosocial well-being, and health behaviors in analytic models, we document some evidence of mediation in the association between changes in wealth and changes in C-reactive protein, which suggests specificity in the social and biophysiological mechanisms relating wealth shocks and health at older ages. Linking macro-level conditions, meso-level household environments, and micro-level biological processes, this study provides new insights into the mechanisms through which economic inequality contributes to disease and mortality risk in late life.

Abstract
C-reactive protein (CRP) is a relatively nonspecific marker of inflammation. However, it can be used to monitor the severity and progression of some well-defined cardiovascular diseases. For example, it can predict serious events in patients with coronary artery disease (CAD) who are hospitalized with acute coronary syndrome, myocardial infarction (MI), or advanced peripheral vascular disease. In this article, the authors review the role of CRP in the diagnosis, monitoring, and treatment of various forms of ischemic and inflammatory cardiovascular disease.

Abstract
BACKGROUND AND AIM C-reactive protein (CRP) is a general marker of inflammation that has been differentially linked with sleep. Elevated CRP (ie, high inflammation) has been associated with either short/insufficient sleep duration or long sleep duration, both, or neither. Daytime napping has also been tied to increased and decreased inflammation. We attempted to unify these findings by examining the relationship between CRP and sleep duration in conjunction with napping in a healthy young adult cohort. PARTICIPANTS Participants were young adults (mean age = 29.05 years, n = 2147) from the National Longitudinal Study of Adolescent Health (Add Health) cohort, a nationally representative longitudinal sample. METHODS/RESULTS Analysis of covariance (ANCOVA) tests examined whether self-reported sleep duration (short, medium, or long) and nap frequency (none-few days/week; most days/week; every day) interacted in relation to CRP. Standard covariates (ie, age, gender, race/ethnicity, body mass index, physical activity, depression, snoring, systolic blood pressure, clinical symptoms, and household income) were used. There was a linear increase in CRP with increased napping [contrast estimate = 0.265, 95% confidence interval (CI) (0.045-0.485), P = 0.018]. There was also an interaction between sleep duration and napping frequency in relation to CRP (F4,2128 = 2.90, P = 0.021). Inflammation differed between nap groups within the long and short sleep groups. CONCLUSIONS Our results suggest that increased napping is an independent predictor of inflammation in young adults. These results also provide evidence for interactive effects of inflammation, nocturnal sleep, and daytime naps. Our findings confirm that excess sleep, insufficient sleep, frequent napping, and infrequent napping can all be linked with elevated CRP, but these relationships depend on both nocturnal and daytime sleep patterns. These analyses will guide future work to more specifically examine sleep-inflammation processes and directionality.

Abstract
BACKGROUND Pentraxin 3 (PTX3), the prototype of long pentraxins, has been described to be associated with endothelial dysfunction in different cardiovascular disorders. No study has yet evaluated the possible direct effect of PTX3 on vascular function. METHODS AND RESULTS Through in vitro experiments of vascular reactivity and ultrastructural analyses, we demonstrate that PTX3 induces dysfunction and morphological changes in the endothelial layer through a P-selectin/matrix metalloproteinase-1 pathway. The latter hampered the detachment of endothelial nitric oxide synthase from caveolin-1, leading to an impairment of nitric oxide signaling. In vivo studies showed that administering PTX3 to wild-type mice induced endothelial dysfunction and increased blood pressure, an effect absent in P-selectin-deficient mice. In isolated human umbilical vein endothelial cells, PTX3 significantly blunted nitric oxide production through the matrix metalloproteinase-1 pathway. Finally, using ELISA, we found that hypertensive patients (n=31) have higher plasma levels of PTX3 and its mediators P-selectin and matrix metalloproteinase-1 than normotensive subjects (n=21). CONCLUSIONS Our data show for the first time a direct role of PTX3 on vascular function and blood pressure homeostasis, identifying the molecular mechanisms involved. The findings in humans suggest that PTX3, P-selectin, and matrix metalloproteinase-1 may be novel biomarkers that predict the onset of vascular dysfunction in hypertensive patients.

Abstract
BACKGROUND Deployed military personnel are vulnerable to chronic sleep disturbance, which is highly comorbid with post-traumatic stress disorder (PTSD) and depression, as well as declines in health-related quality of life (HRQOL). Inflammation is associated with HRQOL declines and sleep-related comorbidities; however, the impact of sleep changes on comorbid symptoms and inflammation in this population is unknown. METHODS In this observational study, we examined the relationship between reported sleep changes and concentrations of inflammatory biomarkers, interleukin 6 (IL-6), and C-reactive protein (CRP) in peripheral blood. The sample was dichotomized into two groups: (1) decrease in Pittsburgh Sleep Quality Index (PSQI; restorative sleep) and (2) no change or increase in PSQI (no change). Mixed between-within subjects analysis of variance tests were used to determine group differences on changes of inflammation and comorbid symptoms. RESULTS In our sample of 66 recently deployed military personnel with insomnia, 34 participants reported restorative sleep whereas 32 reported no sleep changes. The two groups did not differ in demographic or clinical characteristics, with the exception of PTSD diagnosis at baseline. The restorative sleep group had significant reductions in CRP concentrations and depression symptoms, as well as reduced fatigue and improvements in emotional well-being, social functioning, and physical functioning at follow-up. CONCLUSIONS Military personnel who report sleep restoration after deployment have reduced CRP concentrations, decreased severity of depression, and improved HRQOL. These findings suggest that treatment for sleep disturbances may be associated with improvements in mental and physical health, thereby supporting continued study in this line of research.

Abstract
C-reactive protein (CRP), an innate immune mediator, is elevated in the circulation before symptoms in patients with preeclampsia, a severe hypertensive pregnancy disorder with high mortality and morbidity. However, the specific sources underlying increased CRP and the role of elevated CRP in preeclampsia are undefined. Here, we report that circulating CRP levels are significantly increased in a large cohort of normotensive pregnant individuals when compared with nulligravid women and is further increased in patients with preeclampsia. These findings led us to discover further that placental syncytiotrophoblasts are previously unrecognized cellular sources of CRP and underlie elevated CRP in normotensive pregnant women and the additional increase in patients with preeclampsia. Next, we demonstrated that injection of CRP induces preeclampsia features, including hypertension (157 mm Hg CRP treated versus 119 mm Hg control), proteinuria (35.0 mg/μg CRP treated versus 14.1 mg/μg control), kidney, and placental damage and increased levels of sFlt-1 in pregnant mice but not in nonpregnant mice. Our study implicates that phosphocholine transferase, a placental-specific enzyme post-translationally modifying neurokinin B, is essential for the pathogenic role of CRP in preeclampsia through activation of the neurokinin 3 receptor. Overall, our studies have provided significant new insight on the pathogenic role of CRP in preeclampsia and highlighted innovative therapeutic strategies.

Abstract
Pentraxin-3 (PTX3), a modulator of tumor-associated inflammation, is known to be positively correlated with tumor grade and severity of malignancies, but the function and molecular underlying mechanisms of PTX3 remain unclear. In the present study, the expression of PTX3 in human lung adenocarcinoma (LAC) was examined by immunohistochemical assay using a tissue microarray procedure. A loss-of-function experiment was performed to explore the effects of lentiviral vector-mediated PTX3 shRNA (Lv-shPTX3) on cell growth and invasive potential in LAC cell lines (A549 and LETPα-2), assessed by MTT and Transwell assays, respectively. We found that the expression of PTX3 protein was significantly increased in LAC tissues compared with that in adjacent non-cancerous tissues (ANCT) (60.42% vs. 29.17%, P=0.004), and positively correlated with lymphatic invasion of the tumor (P=0.006). Furthermore, knockdown of PTX3 suppressed tumor proliferation and invasion of LAC cells, followed by decreased expression of p-AKT, p-NF-kappa B, PCNA, and MMP-9. Taken together, our findings demonstrate that upregulation of PTX3 expression is correlated with tumor metastasis of LAC patients, and knockdown of PTX3 blocks the development of LAC through inhibition of the AKT and NF-kappa B pathways, suggesting that PTX3 may serve as a potential therapeutic target for the treatment of cancer.

Abstract
Atherothrombosis is no longer considered solely a disorder of lipoprotein accumulation in the arterial wall. Rather, the initiation and progression of atherosclerotic lesions is currently understood to have major inflammatory influences that encompass components of both the innate and acquired immune systems. Promising clinical data for 'upstream' biomarkers of inflammation such as interleukin-6 (IL-6) as well as 'downstream' biomarkers such as C-reactive protein, observations regarding cholesterol crystals as an activator of the IL-1β generating inflammasome, and recent Mendelian randomization data for the IL-6 receptor support the hypothesis that inflammatory mediators of atherosclerosis may converge on the central IL-1, tumour necrosis factor (TNF-α), IL-6 signalling pathway. On this basis, emerging anti-inflammatory approaches to vascular protection can be categorized into two broad groups, those that target the central IL-6 inflammatory signalling pathway and those that do not. Large-scale Phase III trials are now underway with agents that lead to marked reductions in IL-6 and C-reactive protein (such as canakinumab and methotrexate) as well as with agents that impact on diverse non-IL-6-dependent pathways (such as varespladib and darapladib). Both approaches have the potential to benefit patients and reduce vascular events. However, care should be taken when interpreting these trials as outcomes for agents that target IL-6 signalling are unlikely to be informative for therapies that target alternative pathways, and vice versa. As the inflammatory system is redundant, compensatory, and crucial for survival, evaluation of risks as well as benefits must drive the development of agents in this class.

Abstract
Considerable progress has been achieved in the treatment of dyslipidemias. However, half of cardiovascular events occur in individuals with average or low cholesterol levels and there is still a considerable residual risk with 70% of patients having an event despite statin treatment. In the era of personalized medicine there is increased interest in the incorporation of individual biomarkers in risk score algorithms in order to improve cardiovascular risk stratification followed by the prompt initiation of preventive measures. Since the 2001 third report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation and Treatment on High Blood Cholesterol in Adults (ATP III) several studies have evaluated the prognostic value of lipid related biomarkers such as non-HDL-cholesterol, apolipoprotein B, apolipoprotein B/apolipoprotein A1 ratio, lipoprotein(a), lipoprotein-associated phospholipase A2, and C-reactive protein. This article tries to summarize the most recent results in this area.

Abstract
UNLABELLED Serum high-sensitivity C-reactive protein (CRP) is an inflammatory biomarker. We investigated the relationship between CRP and bone health in the Rotterdam Study. Serum high-sensitivity CRP was associated with fracture risk and lower femoral neck bending strength. Mendelian randomization analyses did not yield evidence for this relationship being causal. INTRODUCTION Inflammatory diseases are associated with bone pathology, reflected in a higher fracture risk. Serum high-sensitivity CRP is an inflammatory biomarker. We investigated the relationship between CRP and bone mineral density (BMD), hip bone geometry, and incident fractures in the Rotterdam Study, a prospective population-based cohort. METHODS At baseline, serum high-sensitivity CRP was measured. A weighted genetic risk score was compiled for CRP based on published studies (29 polymorphisms; Illumina HumanHap550 Beadchip genotyping and HapMap imputation). Regression models were reported per standard deviation increase in CRP adjusted for sex, age, and BMI. Complete data was available for 6,386 participants, of whom 1,561 persons sustained a fracture (mean follow-up, 11.6 years). RESULTS CRP was associated with a risk for any type of fracture [hazard ratio (HR) = 1.06; 95 % confidence interval (CI), 1.02-1.11], hip fractures (HR = 1.09; 1.02-1.17) and vertebral fractures [odds ratio (OR) = 1.34; 1.14-1.58]. An inverse relationship between CRP levels and section modulus (-0.011 cm(3); -0.020 to -0.003 cm(3)) was observed. The combined genetic risk score of CRP single nucleotide polymorphisms (SNPs) was associated with serum CRP levels (p = 9 × 10(-56)), but not with fracture risk (HR = 1.00; 0.99-1.00; p = 0.23). CONCLUSIONS Serum high-sensitivity CRP is associated with fracture risk and lower bending strength. Mendelian randomization analyses did not yield evidence for this relationship being causal. Future studies might reveal what factors truly underlie the relationship between CRP and fracture risk.

Abstract
Stroke is a leading cause of death and disability worldwide. A new and exciting development in cardiovascular disease is the recognition of the role of inflammation in atherosclerosis. C-reactive protein, an acute phase reactant, appears to be a promising biomarker for cardiovascular disease, possibly more predictive than cholesterol and also may play an etiological role. C-reactive protein also appears to be predictive of stroke risk, although less so in the elderly. Although the number of studies on stroke (apart from cardiovascular disease) is limited, there is a significant graded increase in stroke risk within the low-to-high normal range of C-reactive protein. C-reactive protein is readily amenable to treatment with anti-inflammatory drugs, such as aspirin and statins. New and increasingly available high-sensitivity assays may make C-reactive protein a standard screening tool for cardiovascular disease.

Abstract
About half of all cancer patients show a syndrome of cachexia, characterized by anorexia and loss of adipose tissue and skeletal muscle mass. Cachexia can have a profound impact on quality of life, symptom burden, and a patient's sense of dignity. It is a very serious complication, as weight loss during cancer treatment is associated with more chemotherapy-related side effects, fewer completed cycles of chemotherapy, and decreased survival rates. Numerous cytokines have been postulated to play a role in the etiology of cancer cachexia. Cytokines can elicit effects that mimic leptin signaling and suppress orexigenic ghrelin and neuropeptide Y (NPY) signaling, inducing sustained anorexia and cachexia not accompanied by the usual compensatory response. Furthermore, cytokines have been implicated in the induction of cancer-related muscle wasting. Cytokine-induced skeletal muscle wasting is probably a multifactorial process, which involves a protein synthesis inhibition, an increase in protein degradation, or a combination of both. The best treatment of the cachectic syndrome is a multifactorial approach. Many drugs including appetite stimulants, thalidomide, cytokine inhibitors, steroids, nonsteroidal anti-inflammatory drugs, branched-chain amino acids, eicosapentaenoic acid, and antiserotoninergic drugs have been proposed and used in clinical trials, while others are still under investigation using experimental animals. There is a growing awareness of the positive impact of supportive care measures and development of promising novel pharmaceutical agents for cachexia. While there has been great progress in understanding the underlying biological mechanisms of cachexia, health care providers must also recognize the psychosocial and biomedical impact cachexia can have.

Abstract
Sorting nexin 27 (SNX27), a brain-enriched PDZ domain protein, regulates endocytic sorting and trafficking. Here we show that Snx27(-/-) mice have severe neuronal deficits in the hippocampus and cortex. Although Snx27(+/-) mice have grossly normal neuroanatomy, we found defects in synaptic function, learning and memory and a reduction in the amounts of ionotropic glutamate receptors (NMDA and AMPA receptors) in these mice. SNX27 interacts with these receptors through its PDZ domain, regulating their recycling to the plasma membrane. We demonstrate a concomitant reduced expression of SNX27 and CCAAT/enhancer binding protein β (C/EBPβ) in Down's syndrome brains and identify C/EBPβ as a transcription factor for SNX27. Down's syndrome causes overexpression of miR-155, a chromosome 21-encoded microRNA that negatively regulates C/EBPβ, thereby reducing SNX27 expression and resulting in synaptic dysfunction. Upregulating SNX27 in the hippocampus of Down's syndrome mice rescues synaptic and cognitive deficits. Our identification of the role of SNX27 in synaptic function establishes a new molecular mechanism of Down's syndrome pathogenesis.

Abstract
The existing paradigm of exercise-induced decreases in chronic inflammation focuses on the expression of inflammatory receptors on systemic monocytes in response to exercise training, with the role of anti-inflammatory receptors largely ignored. Our recent preliminary studies indicate that the anti-inflammatory melanocortin receptors (MCRs) may play a role in modulating exercise-induced decreases in chronic inflammation. Here, we present a study designed to determine the effect of intense, resistance exercise training on systemic monocyte MCR expression. Because low-grade chronic inflammation is associated with elevated cardiometabolic risk in healthy populations and exercise decreases chronic inflammation, we investigated the associations between systemic monocyte cell surface expression of MCRs and inflammatory markers as a possible mechanism for the beneficial anti-inflammatory effects of resistance training. To this end, the present study includes 40 adults (aged 19-27 yr) and implements a 12-wk periodized, intensive resistance training intervention. Melanocortin 1 and 3 receptor expression on systemic monocytes and inflammatory markers, including C-reactive protein (CRP), interleukin (IL)-6, IL-1β, and IL-10, were measured before and after the intervention. Resistance training significantly altered MCR systemic monocyte cell surface expression, had no chronic effects on IL-6, IL-1β, or IL-10 expression, but significantly decreased CRP levels from a moderate to a low cardiovascular disease risk category. More specifically, decreased melanocortin 3 receptor expression significantly correlated with decreased CRP, independent of changes in adiposity. These data suggest that the observed responses in MCR expression and decreases in cardiovascular disease risk in response to resistance training represent an important anti-inflammatory mechanism in regulating exercise-induced decreases in chronic inflammation that occur independent of chronic changes in systemic cytokines.

Abstract
OBJECTIVE Understand the links between race and C-reactive protein (CRP), with special attention to gender differences and the role of class and behavioral risk factors as mediators. METHOD This study utilizes the National Social Life, Health, and Aging Project data, a nationally representative study of older Americans aged 57-85 to explore two research questions. First, what is the relative strength of socioeconomic versus behavioral risk factors in explaining race differences in CRP levels? Second, what role does gender play in understanding race differences? Does the relative role of socioeconomic and behavioral risk factors in explaining race differences vary when examining men and women separately? RESULTS When examining men and women separately, socioeconomic and behavioral risk factor mediators vary in their importance. Indeed, racial differences in CRP among men aged 57-74 are little changed after adjusting for both socioeconomic and behavioral risk factors with levels 35% higher for black men as compared to white men. For women aged 57-74, however, behavioral risk factors explain 30% of the relationship between race and CRP. DISCUSSION The limited explanatory power of socioeconomic position and, particularly, behavioral risk factors, in elucidating the relationship between race and CRP among men, signals the need for research to examine additional mediators, including more direct measures of stress and discrimination.

Abstract
Biomarkers aim at refining risk prediction and at better identifying individuals at high cardiovascular risk. To be recommended in clinical practice, a novel biomarker should be simple to measure, non-invasive, cost-effective, reproducible, and should provide a predictive and discriminative value independently of, and beyond existing risk scores. In addition, it should offer a favourable impact on morbidity, mortality and disability of the disease. Among the hundreds of candidate circulating biomarkers, certain have shown solid statistical associations with the incidence of future events, as is the case for high-sensitivity C-reactive protein. However, contrary to subclinical atherosclerosis assessment, they offer only a modest increase in the predictive value of current scores. To date, the main interest of cardiovascular biomarkers in primary prevention is to better understand pathophysiological mechanisms of atherosclerosis in the research setting.

Abstract
BACKGROUND Diabetes Mellitus (DM) is becoming an increasingly common disease which is the leading cause of chronic renal failure. The pathogenesis of diabetic nephropathy is still a matter of debate. There are conflicting results regarding the relation of C reactive protein (CRP), interleukin-6 (IL-6) and diabetic nephropathy in type 1 diabetes. OBJECTIVES This study was aiming to determine the association between higly sensitive (Hs)-CRP and IL6 with nephropathy in a sample of type 1 diabetic Egyptian patients. MATERIALS AND METHODS The study was conducted on forty type-1 diabetic patients (Group I), who subdivided into three subgroups according to their urine albumin excretion rate (AER); Group IA: 10 patients with AER <20 microg/min, Group IB: 15 patients with AER ranges from 20-200 microg/min. Group IC: 15 patients with AER is > 200 microg/min and 10 healthy subjects as a control (Group II). RESULTS There were high statistical significant difference (p < 0.001) between group I with group II regarding HsCRP (4.39 +/- 1.94, 1.32 +/- 0.39), and IL-6 (2.82 +/- 0.76, 1.95 +/- 0.35). In group I, we found a positive significant correlation (p < 0 .001) between UAE and levels of Hs-CRP (r = 0.927), and IL-6 (r = 0.838), respectively. Also, a positive significant correlation between Hs-CRP and IL-6 (r = 0.728, p < 0.001) was found. Fasting plasma glucose (FPG) level and HbA1c showed a significant positive correlation (p < 0.001) with Hs-CRP (r = 0.531) (r = 0.750), and IL-6 (r = 0. 490) (r = 0.680) respectively. CONCLUSION Hs-CRP and IL-6 are sensitive markers for diabetic nephropathy predicting its progression and severity in type 1 diabetics.

Abstract
Although seasonal variation in high-sensitivity C-reactive protein (hsCRP) has been studied cross-sectionally and longitudinally, the results to date have been mixed. Here, to test seasonal variation in this compound with regard to within-subject, inter-day variation, we conducted a longitudinal follow-up study with repeated measurements in Japanese workers with low hsCRP. Blood samples were obtained from four male indoor daytime workers, who were aged 32-57 and commuted to offices in Kawasaki City, on six days within 2-wk windows in February and October, 2008. Serum hsCRP was measured using ultrasensitive latex-enhanced immunonephelometry. Among the subjects with detectable levels of hsCRP, individual median serum hsCRP levels were 38-74% higher in October than in February (p=0.03). This study identified the presence of a seasonal variation in the serum hsCRP level of Japanese workers with low hsCRP levels.

Abstract
OBJECTIVE Depression is common in patients with coronary artery disease (CAD) and is associated with higher risk of cardiovascular adverse events. We aimed to explore the prognostic role of mild depression on cardiovascular mortality and compare its prognostic value with C-reactive protein (CRP) levels in patients with stable CAD. RESEARCH DESIGN AND METHODS We initially recruited 523 consecutive patients with stable CAD. Glucose, lipids and CRP levels were measured and an echocardiographic study was performed. In addition, depressive symptomatology was assessed with the Zung Depression Rating Scale (ZDRS, range 20-80). Patients on antidepressant treatment or with ZDRS score ≥60 were excluded. Patients were followed up at 6 month intervals (median 33 months, interquartile range 24-40 months) by telephone interview. RESULTS Follow-up data were obtained from 485 patients (92.7%). Nineteen patients with baseline CRP levels >10 mg/L and eight with non-cardiovascular death were excluded from analysis. Of the remaining 458 patients 113 (24.7%) presented cardiac events. Of them 21 died (4.6%), 42 developed acute coronary syndrome (9.2%), 27 (5.9%) had a revascularization procedure due clinical deterioration, two had a stroke (0.44%) and 21 (4.6%) an arrhythmic event. Multivariate Cox regression analysis showed that ZDRS score was independent predictor of cardiovascular death (hazard ratio [HR]: 1.104 with 95% confidence interval [CI]: 1.039-1.172, p = 0.001) after adjustment for conventional risk factors and CRP. The Wald test statistic of CRP was 2.59, whereas the Wald test statistic of ZDRS score was 3.23, indicating better predictability of ZDRS score. ZDRS score was also independent predictor of both cardiovascular death and arrhythmic event (HR: 1.102 with 95% CI: 1.051-1.156, p < 0.001) after adjustment for conventional risk factors and CRP levels. The main limitations of our study were the evaluation of depression at one point in time and the assessment of inflammatory burden by measuring only CRP levels. CONCLUSIONS Mild depression is associated with increased cardiovascular mortality and is a better predictor than CRP levels in patients with stable CAD.

Abstract
In patients with end-stage renal disease (ESRD), inflammation, and protein energy wasting (PEW) are two highly prevalent and interconnected entities, jointly exerting a deleterious effect on multiple other ESRD-specific pathological processes and eventually on patient outcome. With respect to the pathophysiology underlying this strong association, knowledge has been actively expanded over the past few years. As such, it is nowadays recognized that inflammation acts via direct, as well as indirect, pathways in its contribution to PEW. Directly, inflammation causes alterations in amino acid utilization, translating into increased catabolism and decreased anabolism of muscle tissue. Indirectly, inflammation may act via altered ghrelin and adipokine metabolism, adipose tissue distribution, and pathological neuroendocrine signaling, as well as coexistent depression in inducing anorexia and PEW. In addition, two relatively new inflammatory markers (pentraxin-3 and TNF-like weak inducer of apoptosis) have gained attention with respect to their roles in this specific context. The current review deals with recent updates in the literature on the aforementioned pathways connecting inflammation to PEW and subsequent mortality.

Abstract
Although transmembrane C-type lectins (CLs) are known to initiate immune signaling, the participation and mechanism of action of soluble CLs have remained enigmatic. In this study, we found that M-ficolin, a conserved soluble CL of monocyte origin, overcomes its lack of membrane-anchor domain by docking constitutively onto a monocyte transmembrane receptor, G protein-coupled receptor 43 (GPCR43), to form a pathogen sensor-cum-signal transducer. On encountering microbial invaders, the M-ficolin-GPCR43 complex activates the NF-κB cascade to upregulate IL-8 production. We showed that mild acidosis at the local site of infection induces conformational changes in the M-ficolin molecule, which provokes a strong interaction between the C-reactive protein (CRP) and the M-ficolin-GPCR43 complex. The collaboration among CRP-M-ficolin-GPCR43 under acidosis curtails IL-8 production thus preventing immune overactivation. Therefore, we propose that a soluble CL may become membrane-associated through interaction with a transmembrane protein, whereupon infection collaborates with other plasma protein to transduce the infection signal and regulate host defense. Our finding implies a possible mechanism whereby the host might expand its repertoire of immune recognition-cum-regulation tactics by promiscuous protein networking. Furthermore, our identification of the pH-sensitive interfaces of M-ficolin-CRP provides a powerful template for future design of potential immunomodulators.

Abstract
Laser correlation spectroscopy has indicated that plasma C-reactive protein (CRP) is present as a monomer and a pentamer (pentraxin); the latter is similar in physicochemical properties to apolipoproteins, the proteins that transfer fatty acids as nonpolar triglycerides to the cells in the intercellular medium. Concurrently, sepharose column chromatography revealed an association of the bulk of plasma CRP with very low-density lipoproteins. In parallel with CRP, the content of secretory phospholipase A, as a component of lipoproteins is on the rise; the enzyme hydrolyzes phosphatidylcholine in the surface monolayer of lipoproteins to form lysophosphatidylcholine that the CRP-pentamere displays a high affinity binding to. Two different immunochemical assays for CRP suggest that the CRP-monomere and the CRP-pentamere show different functional activity: the CRP-monomere is a humoral immunomodulator while the CRP-pentamere also activates interstitial tissue cells, but differently, by enhancing their energy provision with substrates, namely with saturated and unsaturated fatty acids as triglycerides as components of very low-density lipoproteins via CRP/apoB-100-receptor endocytosis. The vector ligand redirects the flow offatty acids towards the cells that directly show a biological inflammatory response. For this, lipoprotein-associated phospholipase A, hydrolyzes phosphatidylcholine to produce lysophosphatidylcholine that the CRP-pentamere binds to; it superimposes a physiological apoE/B-100-ligand, becomes itself a pathophysiological CRP/B-100-ligand, and directs a flow of the energy substrates towards the interstitial cells that exhibit pathophysiological CRB/B-100-receptors on the membrane. In the arterial intima, the functionally triglyceride-overloaded resident macrophages form lipid spots that form in each systemic inflammatory response or with the elevated plasma levels of a CRP-pentamere and phospholipase A, and are directly unrelated to atheromatosis. It seems likely that we have identified a monomer with the low plasma values of CRP and its bulk (this is a pentamere) with its high plasma values.

Abstract
Bone formation and resorption are influenced by inflammatory processes. We examined the relationships among inflammatory markers and bone mineral content (BMC) and density (BMD) and determined the contribution of inflammatory markers to 1-yr changes in BMC and BMD in healthy postmenopausal women. This analysis included 242 women at baseline from our parent Soy Isoflavones for Reducing Bone Loss project who were randomly assigned to 1 of 3 treatment groups: placebo, 80 mg/d soy isoflavones, or 120 mg/d soy isoflavones. BMD and BMC from the lumbar spine (LS), total proximal femur (hip), and whole body were measured by dual energy X-ray absorptiometry and the 4% distal tibia by peripheral quantitative computed tomography. Serum inflammatory markers (C-reactive protein, interleukin [IL]-1 beta, IL-6, tumor necrosis factor-alpha [TNF-alpha], and white blood cell count [WBC]) were measured at baseline, 6, and 12 mo. Because of attrition or missing values, data analysis at 12 mo includes only 235 women. Significant associations among IL-6, TNF-alpha, and WBC were observed with percent change in LS, hip, and whole body BMC and BMD. Multiple regression analysis indicated that in combination inflammatory markers accounted for 1.1-6.1% of the variance to the observed 12-mo changes in BMC and BMD. Our results suggest that modifying inflammatory markers, even in healthy postmenopausal women, may possibly reduce bone loss.

Abstract
Insulin resistance, which plays a fundamental role in the pathogenesis of metabolic syndrome and type 2 diabetes mellitus, is associated with serum levels of inflammatory markers and abdominal obesity. Whether insulin resistance is caused by inflammation or is an epiphenomenon of obesity remains unresolved. We therefore conducted a cross-sectional study to investigate whether the association between insulin resistance and C-reactive protein (CRP) levels is independent of abdominal obesity in a nondiabetic Taiwanese population. The study included 574 Taiwanese participants (300 men and 274 women) who were nondiabetic persons with CRP levels not exceeding 10 mg/L and who did not have a history of cardiovascular disease or were taking medication for dyslipidemia. All participants were of Han-Chinese origin. The degree of insulin resistance was determined using the homeostasis model assessment of insulin resistance (HOMA-IR). The CRP levels were categorized into quartiles from the lowest to the highest concentrations (Q1-Q4). Blood pressure, fasting glucose level, triglycerides level, waist circumference, and HOMA-IR were all found to be significantly higher in Q3 and Q4 than in Q1 and Q2. Stratified analysis by sex and abdominal obesity showed that HOMA-IR was significantly associated with CRP levels in both sexes in either obese or nonobese populations. Multiple linear regression analysis adjusting for age, smoking, components of metabolic syndrome, and waist circumference showed that the association between HOMA-IR and CRP levels remained significant in both men and women (P = .029 for men and P < .001 for women). These findings confirm that insulin resistance is strongly associated with CRP levels independent of abdominal obesity in nondiabetic Taiwanese. Factors other than abdominal obesity, such as polymorphisms in the CRP gene, may influence the association of insulin resistance with CRP levels in different ethnic populations.

Abstract
BACKGROUND Within the general population, levels of C-reactive protein (CRP) are positively associated with atherosclerotic cardiovascular disease (CVD). Whether CRP is causally implicated in atherogenesis or is the results of atherosclerosis is disputed. A role of CRP to protect endothelium-derived nitric oxide (EDNO) has been suggested. We examined the association of CRP with EDNO-dependent vasomotor function and subclinical measures of atherosclerosis and arteriosclerosis in patients with raised CRP resulting from rheumatoid arthritis (RA). METHODOLOGY/PRINCIPAL FINDINGS Patients with RA (n = 59) and healthy control subjects (n = 123), underwent measures of high sensitivity CRP, flow-mediated dilation (FMD, dependent on EDNO), intima-media thickness (IMT, a measure of subclinical atherosclerosis) and aortic pulse wave velocity (PWV, a measure of arteriosclerosis). IMT and PWV were elevated in patients with RA compared to controls but FMD was similar in the two groups. In patients with RA, IMT and PWV were not correlated with CRP but FMD was positively independently correlated with CRP (P<0.01). CONCLUSIONS/SIGNIFICANCE These findings argue against a causal role of CRP in atherogenesis and are consistent with a protective effect of CRP on EDNO bioavailability.

Abstract
Native C-reactive protein (nCRP) is a pentameric oligo-protein and an acute phase reactant whose serum expression is increased in patients with inflammatory disease. We have identified by immunohistochemistry, significant expression of a tissue-binding insoluble modified version or monomeric form of CRP (mCRP) associated with angiogenic microvessels in peri-infarcted regions of patients studied with acute ischaemic stroke. mCRP, but not nCRP was expressed in the cytoplasm and nucleus of damaged neurons. mCRP co-localized with CD105, a marker of angiogenesis in regions of revascularisation. In vitro investigations demonstrated that mCRP was preferentially expressed in human brain microvessel endothelial cells following oxygen-glucose deprivation and mCRP (but not column purified nCRP) associated with the endothelial cell surface, and was angiogenic to vascular endothelial cells, stimulating migration and tube formation in matrigel more strongly than fibroblast growth factor-2. The mechanism of signal transduction was not through the CD16 receptor. Western blotting showed that mCRP stimulated phosphorylation of the key down-stream mitogenic signalling protein ERK1/2. Pharmacological inhibition of ERK1/2 phosphorylation blocked the angiogenic effects of mCRP. We propose that mCRP may contribute to the neovascularization process and because of its abundant presence, be important in modulating angiogenesis in both acute stroke and later during neuro-recovery.

Abstract
Experimental studies indicate that the proinflammatory cytokines interleukin-1, interleukin-6, and tumor necrosis factor-alpha are important regulators of bone resorption and may play an important role in age- and estrogen deficiency-related bone loss. Although the observation of accelerated bone loss in patients with inflammatory disorders supports this mechanism, the role of cytokines in the etiology of osteoporosis has yet to be determined. Elucidation of this potential relationship could not only provide clinicians with an additional tool to identify patients at risk for osteoporosis, but may also inform the development of cytokine-blocking therapies as potential interventions to curb bone loss. Although some epidemiologic studies suggest increases in proinflammatory cytokines are associated with decreased bone mass and greater fracture risk, the totality of evidence is limited and provides no clear indication of which cytokines may be most important for bone health. Additional studies are required to establish if inflammation is an important risk factor for osteoporosis.

Abstract
C-reactive protein (CRP) is a widely used systemic biomarker for diagnosing acute and chronic inflammation. During the past decade, serum CRP has been re-emphasized by extending its clinical use to the prediction or diagnosis of cardiovascular diseases and other conditions, particularly malignancies. Serum CRP has also been found to be elevated in patients with many malignancies, implying a close linkage between inflammation and malignancy. Prospective studies have shown a higher risk of developing cancer in those with elevated serum CRP. CRP is produced by hepatocytes in response to inflammatory cytokines, particularly, interleukin-6 from the tumor microenvironment. Preoperative CRP levels are parallel to the progression or pathological stages of malignancies, including gastric cancer in patients in our series. Elevated CRP is a determinant predictor of lower survival rates in patients with several cancers, including esophageal, colorectal, hepatocellular, pancreatic, urinary bladder, renal,ovarian and cervical cancer, after surgical resection. The measurement of serum CRP is simple, cheap, and available in daily practice. It can serve as an additional prognostic predictor for survival and post-treatment monitoring in cancer patients. In the future, CRP-lowering agents might offer a promising benefit in the prevention and therapy of many different types of cancer.
