question:
Context: Clusterin (CLU) /Apolipoprotein J is a protein biosensor of oxidative stress and inflammation, which is upregulated in many pathological processes including atherosclerosis. Previous studies have shown that in aortic tissue, CLU expression increases with atherosclerotic lesion progression and it has been coupled with vascular damage and coronary artery disease. A few studies enter into CLU and carotid atherosclerosis while the apolipoprotein's expression on human carotid tissue and its association with parameters related to the disease development has not been examined. The present study was designed to reveal the relationships between the degree of CLU immunolocalization on carotid artery and demographic characteristics, blood parameters and pharmacological treatment of patients underwent internal carotid artery endarterectomy.", "CLU expression was detected by immunohistochemistry in 42 carotid endarterectomy specimens. Patients' serum levels of tumor necrosis factor-a (TNF-a), interleukin-6 (IL-6), high sensitive C-reactive protein (hsCRP) and classical parameters related to atherosclerosis such as lipid profile, as well as thrombosis related parameters such as fibrinogen, antithrombin III, protein C and protein S were determined. Demographic characteristics, smoking habits and the use of medications were recorded. Comparisons between groups were performed by students't-test and analysis of variance. Independent associations with CLU expression on carotid tissue were denoted by linear regression analysis.", 'CLU imuunolocalization was denser in smokers than in non-smokers (p\u2009=\u20090.041) while it was rarefied in specimens of patients on cropidogrel treatment (p\u2009=\u20090.045) compared to the rest not taking this medication. Clopidogrel intake was independent predictor of lower CLU expression on carotid artery (p =0.045). CLU was positively correlated with serum TNF-a concentration (r\u2009=\u20090.33, p\u2009=\u20090.040) that was independent predictor of higher expression of the apolipoprotein (p\u2009=\u20090.001). IL-6, hsCRP and classical parameters related to atherosclerosis and thrombosis were not associated with CLU immunolocalization.
Answer: Our study suggests that CLU expression on carotid artery is affected by TNF-alpha, cigarette smoking confirming its association with oxidative and cellular stress and anti-platelet medication reflecting the protective effects of such pharmacological treatment on vascular wall.
answer:
Is clusterin/Apolipoprotein J immunolocalization on carotid artery affected by TNF-alpha , cigarette smoking and anti-platelet treatment?


question:
Context: To determine the role of herpes simplex virus-1 (HSV-1) glycoprotein K(gK) in corneal infection, neuroinvasion, and virus latency in trigeminal ganglia of mice.', 'The recombinant virus HSV-1 (McKrae) Delta gK (MKDelta gK) carrying a deletion of the gK gene was constructed by insertional/deletion mutagenesis and replaced by a gene cassette constitutively expressing the enhanced green fluorescence protein. The gK deletion of the MKDelta gK virus was rescued to produce the wild-type-like virus MKgK. Balb/c mice were infected ocularly with either virus, and the infection pattern in the eye, clinical disease progression, and establishment of viral latency was monitored.', 'Mice infected with the MKDelta gK strain produced in a gK complementing cell line did not exhibit clinical signs when compared with mice infected with the MKgK virus. Direct visualization of infected eyes revealed that the MKDelta gK virus was unable to spread in mouse corneas, while the MKgK rescued virus spread efficiently. Nineteen of 20 scarified and 5/12 unscarified mice infected with the MKgK virus produced infectious virus after coculture with permissive cells, while 0/20 scarified and 0/12 unscarified mice infected with the MKDelta gK virus produced infectious virus. HSV DNA was detected in trigeminal ganglia by PCR in 19/20 scarified and 9/12 unscarified mice inoculated with MKgK, while HSV DNA was detected in the trigeminal ganglia of 3/20 scarified and 0/12 unscarified mice inoculated with MKDelta gK.
Answer: The results show that HSV-1 gK is essential for efficient replication and spread in the corneal epithelium and trigeminal ganglia neuroinvasion in MKDelta gK inoculated mice.
answer:
Is the herpes simplex virus type 1 ( HSV-1 ) glycoprotein K ( gK ) essential for viral corneal spread and neuroinvasiveness?


question:
Context: The CARD14 gene encodes a protein that enhances nuclear factor (NF)-κB activation and the upregulation of proinflammatory pathway genes. CARD14 is upregulated in psoriatic vs. normal skin, and rare and common CARD14 variants have been associated with the risk of developing psoriasis. Our hypothesis was that CARD14 variants could also influence the response to antitumour necrosis factor (anti-TNF) therapies among patients with psoriasis.', 'To determine whether CARD14 gene variants were linked to a significant positive anti-TNF response in patients with psoriasis.', 'DNA from 116 patients with psoriasis was subjected to next-generation sequencing of the CARD14 gene. All of the patients were nonresponders or had contraindications to conventional systemic treatments.', 'A reduction of at least 75% in Psoriasis Area and Severity Index (PASI 75) at week 24 was considered a positive response to treatment. In total 116 patients (79 responders and 37 nonresponders) were next-generation sequenced, and we identified five nucleotide variants that would result in missense amino acid changes. These variants were determined in all of the patients, and allele and genotype frequencies were compared between the two groups. We found a significantly higher frequency of rs11652075 CC (p.Arg820Trp) among the group with a positive response (P = 0.01, odds ratio 3.71, 95% confidence interval 1.30-10.51). Furthermore, among responders, six patients were heterozygous carriers of the rare p.Glu422Lys variant, and two patients were heterozygous for p.Arg682Trp (P = 0.04).
Answer: The common CARD14 p.Arg820Trp variant might have a significant effect on the response to anti-TNF therapies among patients with psoriasis. In addition, rare CARD14 missense variants could also predispose to a better response.
answer:

Do common and rare CARD14 gene variants affect the antitumour necrosis factor response among patients with psoriasis?
