It is known that the serum in cancer patients has the characteristics of the heat-stability. The factor produce the heat-stability is known to be due to tumor marker(TM) such as CEA, CA125(glycoprotein), CA19-9, CA15-3, SLX, CA50, CA72-4, DU-PAN-2, ST-439, SPAN-1(mucin) and alpha 1-acid glycoprotein, IAP(acute reactants). CEA belongs to IgG supergene family protein and is not oncofetal protein. CA19-9 is synthesis in subjects with Le(a) or Le(b) type, but negative in Le(a- b-) type. Thus, CA19-9 is not available as TM in Le(a- b-) type. Many TMs can be classified in 3 types because cancer cell has the character of immature cells which composed of immature proteins or glycoproteins. (1) Oncofetal protein: AFP(fetal albumin), PTHrP(fetal PTH) (2) The immature isozyme type: increase of amylase(salivary type), CPK(brain type) and aldolase (muscle and brain type) (3) The immature protein in biosynthesis process: increase of precursor protein(prepro type or pro type) such as PIVKA-II(preprothrombin), ProGRP, TPA or CYFRA 21-1(pro-keratin?) and hormone precursor in hormone producing tumor.

Case 1. A 23-year-old white housewife presented with an erythematous violaceous rash on her face, neck, chest, and limbs, particularly over the dorsum of the hands and fingers; diffuse alopecia; and an inability to climb stairs and get up from a low seat. The clinical examination showed red to violaceous well-demarcated plaques on sun-exposed areas on the dorsum of the fingers and hands, with periungual erythema and telangiectasia; facial erythema; and heliotrope rash. There was also symmetric involvement of proximal muscles of the limbs. Laboratory examination showed hypergammaglobulinemia, elevated serum aspartate aminotransferase, and serum alanine aminotransferase; normal activities of creatinokinase, lactate dehydrogenase, and aldolase; an antinuclear antibody titer of 1:40 with a speckled pattern; negative anti-DNA and anti-Scl70; and normal serum complement levels (C3, C4, and CH50). Urinalysis results were within normal limits. Skin biopsy histopathology showed hyperkeratosis, edema of the upper epidermis, scattered inflammatory infiltrate, and focal accumulation of mucin in the form of acid mucopolysaccharides. Deep asymptomatic nodules on the inner upper limbs appeared later. Histopathology of these lesions showed focal areas of lobular panniculitis in the subcutaneous tissue, with lymphoplasmocytic inflammatory infiltrate without vasculitis (Figure 1 and Figure 2). Case 2. A 29-year-old white housewife presented with an erythematous violaceous rash on her face, neck, chest, and lower extremities. Clinical examination showed red to violaceous well-demarcated aching plaques on the internal surface of the thighs and tips of the fingers; periungual erythema and digital petechiae; Raynaud's phenomenon; and bilateral ulnar and cervical enlarged lymph nodes. Laboratory examination showed elevated serum aspartate aminotransferase, alanine aminotransferase, creatinokinase, lactate dehydrogenase, and aldolase; negative venereal disease research test results; an antinuclear antibody titer of 1:1024 with speckled pattern; negative anti-DNA and anti-Scl70; and normal serum complement levels (C3, C4, and CH50). Urinalysis results were within normal limits. Histopathology of the deep asymptomatic nodule on the inner left thigh showed lobular panniculitis with a scattered inflammatory infiltrate and diffuse fat necrosis, in addition to calcium deposition between the lipocytes and microcysts without vasculitis (Figure 3).

The secretome of a parasite in its definitive host can be considered to be its genome in trans, to the extent that secreted products encoded by the parasite fulfill their function in the host milieu. The 'extended phenotype' of the filarial parasite, Brugia malayi, is of particular interest because of the evidence that infection results in potent down-modulation of the host immune response. We collected B. malayi 'excretory-secretory' (BES) proteins from adult parasites and using a combination of shotgun LC-MS/MS and 2D gel electrophoresis, identified 80 B. malayi and two host proteins in BES, of which 31 (38%) were detectable in whole worm extract (BmA). Products which were enriched in BES relative to BmA included phosphatidylethanolamine-binding protein (PEB), leucyl aminopeptidase (LAP, homologue of ES-62 from the related filaria Acanthocheilonema viteae), N-acetylglucosaminyltransferase (GlcNAcT) and galectin-1, in addition to the previously described major surface glycoprotein, glutathione peroxidase (gp29, GPX-1) and the cytokine homologue macrophage migration inhibitory factor (MIF-1). One of the most abundant released proteins was triose phosphate isomerase (TPI), yet many other glycolytic enzymes (such as aldolase and GAPDH) were found only in the somatic extract. Among the more prominent novel products identified in BES were a set of 11 small transthyretin-like proteins, and three glutamine-rich-repeat mucin-like proteins. Notably, no evidence was found of any secreted protein corresponding to the genome of the Wolbachia endosymbiont present in B. malayi. Western blotting with anti-phosphorylcholine (PC) monoclonal antibody identified that GlcNAcT, and not the ES-62 homologue, is the major PC-bearing protein in BES, while probing with human filariasis sera showed preferential reactivity to galectin-1 and to processed forms of myotactin. Overall, this analysis demonstrates selective release of a suite of newly identified proteins not previously suspected to be involved at the host-parasite interface, and provides important new perspectives on the biology of the filarial parasite.

Adhesion to intestinal mucosa is a crucial property for probiotic bacteria. Adhesion is thought to increase host-bacterial interactions, thus potentially enabling health benefits to the host. Molecular events connected with adhesion and surface proteome changes were investigated for the probiotic Lactobacillus acidophilus NCFM cultured with established or emerging prebiotic carbohydrates as carbon source and in the presence of mucin, the glycoprotein of the epithelial mucus layer. Variation in adhesion to HT29-cells and mucin was associated with carbon source and mucin-induced subproteome abundancy differences. Specifically, while growth on fructooligosaccharides (FOS) only stimulated adhesion to intestinal HT-29 cells, cellobiose and polydextrose in addition increased adhesion to mucin. Adhesion to HT-29 cells increased by about 2-fold for bacteria grown on mucin-supplemented glucose. Comparative 2DE-MS surface proteome analysis showed different proteins in energy metabolism appearing on the surface, suggesting they exert moonlighting functions. Mucin-supplemented bacteria had relative abundance of pyruvate kinase and fructose-bisphosphate aldolase increased by about 2-fold while six spots with 3.2-2.1 fold reduced relative abundance comprised elongation factor G, phosphoglycerate kinase, BipAEFTU family GTP-binding protein, ribonucleoside triphosphate reductase, adenylosuccinate synthetase, 30S ribosomal protein S1, and manganese-dependent inorganic pyrophosphatase. Surface proteome of cellobiose- compared to glucose-grown L. acidophilus NCFM had phosphate starvation inducible protein stress-related, thermostable pullulanase, and elongation factor G increasing 4.4-2.4 fold, while GAPDH, elongation factor Ts, and pyruvate kinase were reduced by 2.0-1.5 fold in relative abundance. Addition of recombinant L. acidophilus NCFM elongation factor G and pyruvate kinase to a coated mucin layer significantly suppressed subsequent adhesion of the bacterium.

The comparative proteomic data presented in this article provide supporting information to the related research article "Proteomic identification of elevated saliva kallikrein levels in the mdx-4cv mouse model of Duchenne muscular dystrophy " (Murphy et al., 2018). Here we provide additional datasets on the comparative proteomic analysis of saliva and serum proteins and the mass spectrometric identification of kallikrein isoform Klk-1 in wild type versus mdx-4cv saliva specimens. The data article presents the systematic identification of the assessable saliva proteome and the differential presence of proteins in saliva versus serum samples. Representative mass spectrometric scans of unique peptides that were employed to identify the kallikrein isoform Klk-1 in wild type versus mdx-4cv saliva specimens are provided. The dataset contains typical saliva-associated marker proteins, including alpha-amylase and albumin, as well as distinct isoforms of cystatin, serpin, kallikrein, cathepsin, glutathione transferase, carbonic anhydrase, mucin, pyruvate kinase, and aldolase.

Sialic acid (N-acetylneuraminic acid (Neu5Ac)) is commonly found in the terminal location of colonic mucin glycans where it is a much-coveted nutrient for gut bacteria, including Ruminococcus gnavus. R. gnavus is part of the healthy gut microbiota in humans, but it is disproportionately represented in diseases. There is therefore a need to understand the molecular mechanisms that underpin the adaptation of R. gnavus to the gut. Previous in vitro research has demonstrated that the mucin-glycan-foraging strategy of R. gnavus is strain dependent and is associated with the expression of an intramolecular trans-sialidase, which releases 2,7-anhydro-Neu5Ac, rather than Neu5Ac, from mucins. Here, we unravelled the metabolism pathway of 2,7-anhydro-Neu5Ac in R. gnavus that is underpinned by the exquisite specificity of the sialic transporter for 2,7-anhydro-Neu5Ac and by the action of an oxidoreductase that converts 2,7-anhydro-Neu5Ac into Neu5Ac, which then becomes a substrate of a Neu5Ac-specific aldolase. Having generated an R. gnavus nan-cluster deletion mutant that lost the ability to grow on sialylated substrates, we showed that-in gnotobiotic mice colonized with R. gnavus wild-type (WT) and mutant strains-the fitness of the nan mutant was significantly impaired, with a reduced ability to colonize the mucus layer. Overall, we revealed a unique sialic acid pathway in bacteria that has important implications for the spatial adaptation of mucin-foraging gut symbionts in health and disease.
