Mouliou DS. C-Reactive Protein: Pathophysiology, Diagnosis, False Test Results and a Novel Diagnostic Algorithm for Clinicians. Diseases 2023; 11:132. [PMID: 37873776 PMCID: PMC10594506 DOI: 10.3390/diseases11040132] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 09/15/2023] [Accepted: 09/19/2023] [Indexed: 10/25/2023] Open
Abstract
The current literature provides a body of evidence on C-Reactive Protein (CRP) and its potential role in inflammation. However, most pieces of evidence are sparse and controversial. This critical state-of-the-art monography provides all the crucial data on the potential biochemical properties of the protein, along with further evidence on its potential pathobiology, both for its pentameric and monomeric forms, including information for its ligands as well as the possible function of autoantibodies against the protein. Furthermore, the current evidence on its potential utility as a biomarker of various diseases is presented, of all cardiovascular, respiratory, hepatobiliary, gastrointestinal, pancreatic, renal, gynecological, andrological, dental, oral, otorhinolaryngological, ophthalmological, dermatological, musculoskeletal, neurological, mental, splenic, thyroid conditions, as well as infections, autoimmune-supposed conditions and neoplasms, including other possible factors that have been linked with elevated concentrations of that protein. Moreover, data on molecular diagnostics on CRP are discussed, and possible etiologies of false test results are highlighted. Additionally, this review evaluates all current pieces of evidence on CRP and systemic inflammation, and highlights future goals. Finally, a novel diagnostic algorithm to carefully assess the CRP level for a precise diagnosis of a medical condition is illustrated.

Plasma proteome profiling discovers novel proteins associated with non-alcoholic fatty liver disease. Mol Syst Biol 2019; 15:e8793. [PMID: 30824564 PMCID: PMC6396370 DOI: 10.15252/msb.20188793] [Citation(s) in RCA: 156] [Impact Index Per Article: 31.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2018] [Revised: 01/27/2019] [Accepted: 01/28/2019] [Indexed: 12/15/2022] Open
Abstract
Non-alcoholic fatty liver disease (NAFLD) affects 25% of the population and can progress to cirrhosis with limited treatment options. As the liver secretes most of the blood plasma proteins, liver disease may affect the plasma proteome. Plasma proteome profiling of 48 patients with and without cirrhosis or NAFLD revealed six statistically significantly changing proteins (ALDOB, APOM, LGALS3BP, PIGR, VTN, and AFM), two of which are already linked to liver disease. Polymeric immunoglobulin receptor (PIGR) was significantly elevated in both cohorts by 170% in NAFLD and 298% in cirrhosis and was further validated in mouse models. Furthermore, a global correlation map of clinical and proteomic data strongly associated DPP4, ANPEP, TGFBI, PIGR, and APOE with NAFLD and cirrhosis. The prominent diabetic drug target DPP4 is an aminopeptidase like ANPEP, ENPEP, and LAP3, all of which are up-regulated in the human or mouse data. Furthermore, ANPEP and TGFBI have potential roles in extracellular matrix remodeling in fibrosis. Thus, plasma proteome profiling can identify potential biomarkers and drug targets in liver disease.

Abstract
Breast cancer is a major global health concern, appealing for precise prognostic approaches. Thus, the need is to have studies focusing on the identification and recognition of preliminary events leading to the disease. The present study reports the tracing of precancerous progression and serum proteomic analysis in a breast cancer model developed as a result of 7,12-dimethylbenz[a]anthracene (DMBA) administration. Mammary gland histological changes of prime importance were examined by histopathology, and immunohistochemical analysis with Ki-67 was performed to monitor enhanced cell proliferation, right from the onset of hyperplasia till neoplasia. Serum proteomics (one-dimensional (1D) and two-dimensional (2D) electrophoresis, followed by MALDI-TOF MS characterization) was performed to decipher the differentially expressed serum proteins in animals undergoing tumorigenesis vis-à-vis controls. The significance of our study lies in reporting the significantly reduced expression of two proteins: histone-lysine N-methyltransferase (SETD2) and sorting nexin-9 (SNX9) at very early stage (13 weeks) of tumorigenesis, while the full-fledged tumors developed after 6 months. The reduced expression of SETD2 and SNX9 was validated by western blotting and relative expression analysis using quantitative real-time PCR. These proteins may hence prove as potentially useful tools in search for prognostic markers for the early detection of mammary cancer.

Salvianolic acid B protects against chronic alcoholic liver injury via SIRT1-mediated inhibition of CRP and ChREBP in rats. Toxicol Lett 2016; 267:1-10. [PMID: 27989594 DOI: 10.1016/j.toxlet.2016.12.010] [Citation(s) in RCA: 40] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2016] [Revised: 12/08/2016] [Accepted: 12/13/2016] [Indexed: 12/20/2022]
Abstract
Salvianolic acid B (SalB), a water-soluble polyphenol extracted from Radix Salvia miltiorrhiza, has been reported to possess many pharmacological activities. This study investigated the hepatoprotective effects of SalB in chronic alcoholic liver disease (ALD) and explored the related signaling mechanisms. In vivo, SalB treatment significantly attenuated ethanol-induced liver injury by blocking the elevation of serum aminotransferase activities and markedly decreased hepatic lipid accumulation by reducing serum and liver triglyceride (TG) and total cholesterol (TC) levels. Moreover, SalB treatment ameliorated ethanol-induced hepatic inflammation by decreasing the levels of hepatotoxic cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). Importantly, SalB pretreatment significantly increased the expression of SIRT1 and downregulated the expression of inflammatory mediator C-reactive protein (CRP) and lipoprotein carbohydrate response element-binding protein (ChREBP). In vitro, SalB significantly reversed ethanol-induced down-regulation of SIRT1 and increased CRP and ChREBP expression. Interestingly, the effects of SalB on SIRT1, CRP and ChREBP were mostly abolished by treatment with either SIRT1 siRNA or EX527, a specific inhibitor of SIRT1, indicating that SalB decreased CRP and ChREBP expression by activating SIRT1. SalB exerted anti-steatotic and anti-inflammatory effects against alcoholic liver injury by inducing SIRT1-mediated inhibition of CRP and ChREBP expression.

Abstract
Zhi-Zi-Da-Huang decoction (ZZDHD), a classic traditional Chinese medicine (TCM) formula, has been used for centuries to treat alcoholic liver disease. Reliable therapeutics of ZZDHD has also been validated in clinical practice. In this study, molecular docking and network analysis were carried out to explore the antioxidative mechanism of ZZDHD as an effective therapeutic approach to treat alcoholic liver disease. Multiple active compounds of ZZDHD were screened based on four key original enzymes (cytochrome P450 2E1, xanthine oxidase, inducible nitric oxide synthase, and cyclooxygenase-2) involved in ethanol-induced oxidative stress damage. A drug-target network was constructed through network pharmacology analysis, which predicted the relationships of active ingredients to the targets. Some results had been verified by the previous experimental pharmacological studies; meanwhile, it was first reported that xanthine oxidase and eriocitrin, neoeriocitrin, isorhoifolin, and poncirin had interactions. The network pharmacology strategy used provided a forceful tool for searching the mechanism of action of TCM formula and novel bioactive ingredients.

Abstract
The survivals of gastric cancer (GC) patients are associated with early diagnosis and effective treatments. Therefore, it is urgent for the discovery of early GC biomarkers and tumor-targeting therapeutics. The aim of this study was to uncover putative tissue biomarkers of GC using 2D DIGE and then apply one of these specific markers in GC treatment. We found three putative biomarkers of GC with significant differences in expression level compared to adjacent normal tissue, including glucose-regulated protein 78 (GRP78) and glutathione s-transferase pi (GSTpi) with increased expression level, and alpha-1 antitrypsin (A1AT) with reduced expression level. The overexpressed GRP78 was used as a targeted protein for guiding the drugs to tumor cells, leading to more effective treatment for GC xenografts. Our results demonstrated that the designated GRP78-binding peptide based on the sequence, WIFPWIQL, was selectively prone to recognize and bind to GC MKN45 cells in vitro, and also improve the delivery efficiency of polymeric micelles-encapsulated drugs into tumor cells and displayed better therapeutic outcome in experimental animals. This strategy of GRP78-mediated drug targeting system may bring chemotherapeutic drugs with more precise targeting to tumor cells, leading to minimize side effects on patients after chemotherapy.

Abstract
AIM: To screen differentially expressed serum proteins in patients with hepatitis B virus (HBV)-related liver fibrosis using isobaric tags for relative and absolute quantitation (iTRAQ) combined with mass spectrometry.
METHODS: Thirty patients with HBV-related liver fibrosis and 30 healthy volunteers were selected, and their serum samples, after removal of 14 kinds of high-abundant proteins, were used for screening serum differentially expressed serum proteins using iTRAQ labeling and MALDI-TOF-MS. Differentially expressed serum proteins were then analyzed using biological methods.
RESULTS: A total of 274 serum proteins were identified in both healthy volunteers and patients with HBV-related liver fibrosis by mass spectrometry, of which 20 were differentially expressed between the two groups of subjects. Of the 20 differentially expressed serum proteins, 13 were up-regulated and 7 down-regulated. These differentially expressed proteins are involved in 48 biological processes, 8 cellular components, and 12 molecular pathways. APOC3, CLU, C4B, CRP, and APOE were found to be located in the connected nodes of the protein functional interaction network.
CONCLUSION: Serum proteins of APOC3, CLU, C4B, CRP and APOE may play an important role in the development and progression of HBV-related liver fibrosis.

Analysis of plasma proteome from cases of the different traditional Chinese medicine syndromes in patients with chronic hepatitis B. J Pharm Biomed Anal 2011; 59:173-8.

Abstract
A proteomic analysis method, two dimensional gel electrophoresis (2-DE) followed by matrix-assisted laser desorption/ionization time-of-flight MS (MALDI-TOF-MS), was used to explore the link between plasma proteome and the different syndromes of traditional Chinese medicine (TCM) in patients with chronic hepatitis B (CHB). In compared with the plasma proteomes from health donors, the alterations in protein expression from cases of the five TCM syndromes, including damp heat stasis in the middle-Jiao syndrome, liver Qi stagnation and spleen deficiency syndrome, spleen and kidney Yang deficiency syndrome, liver and kidney Yin deficiency syndrome, and blood stasis into collateral syndrome with CHB were identified (P<0.05). In the cases of the five TCM syndromes with CHB, immunoglobulin J-chains (IGJ) and C-reactive protein (CRP) were up-regulated, while haptoglobin (HPT), retinol binding protein (RBP) and vitronectin were down-regulated. To further confirm these results, four proteins, including CRP, IGJ, HPT and RBP, from more plasma samples were quantified by ELISA. The results showed that the changes of protein levels were consistent with those from the 2-DE experiment. Importantly, the upregulation tendency of IGJ level in plasma is related with the different TCM syndromes with CHB (P<0.05). Our results show that IGJ may serve as a novel potential biomarker for diagnosis of the different TCM syndromes in patients with CHB.
