Megjegyzések:Aim. To evaluate tear film parameters and relationship of objective clinical signs and subjective symptoms of dry eye disease (DED) in inflammatory bowel disease (IBD) subgroups. Methods. 39 patients with Crohn's disease (CD), 26 patients with ulcerative colitis (UC), and 39 control persons with no ocular symptoms or surface disorders were included in this prospective, case-control, and cross-sectional study. The ocular surface disease index (OSDI) questionnaire was applied to evaluate dry eye symptoms, and objective tests of DED were performed on both eyes of each subject. Results. The average of OSDI scores was 30.59 (+/- 16.68) in CD patients, 24.67 (+/- 23.48) in UC patients, and 11.19 (+/- 5.8) in controls. Except for tear film breakup time (tBUT) and Schirmer-I values other objective parameters were better in UC patients, than in CD patients. CD patients rather than UC patients tend to develop DED. This was associated with immunosuppressant and TNF- inhibitor use. Conclusions. Clinicians must be aware of the spectrum of DED involvement in IBD and suggest using artificial tears in order to decrease severity of ocular complications.

Cím:Oxidative stress, hypoxia, and autophagy in the neovascular processes of age-related macular degeneration / Janus Blasiak, Goran Petrovski, Zoltán Veréb, Andrea Facskó, Kai Kaarniranta
Dátum:2014
ISSN:2314-6133 2314-6141
Megjegyzések:Age-related macular degeneration (AMD) is the leading cause of severe and irreversible loss of vision in the elderly in developed countries. AMD is a complex chronic neurodegenerative disease associated with many environmental, lifestyle, and genetic factors. Oxidative stress and the production of reactive oxygen species (ROS) seem to play a pivotal role in AMD pathogenesis. It is known that the macula receives the highest blood flow of any tissue in the body when related to size, and anything that can reduce the rich blood supply can cause hypoxia, malfunction, or disease. Oxidative stress can affect both the lipid rich retinal outer segment structure and the light processing in the macula. The response to oxidative stress involves several cellular defense reactions, for example, increases in antioxidant production and proteolysis of damaged proteins. The imbalance between production of damaged cellular components and degradation leads to the accumulation of detrimental products, for example, intracellular lipofuscin and extracellular drusen. Autophagy is a central lysosomal clearance system that may play an important role in AMD development. There are many anatomical changes in retinal pigment epithelium (RPE), Bruch's membrane, and choriocapillaris in response to chronic oxidative stress, hypoxia, and disturbed autophagy and these are estimated to be crucial components in the pathology of neovascular processes in AMD.

Cím:Vitamin D Receptor Gene Polymorphisms and Haplotypes in Hungarian Patients with Idiopathic Inflammatory Myopathy / Bodoki Levente, Chen Ji-Qing, Zeher Margit, Nagy-Vincze Melinda, Griger Zoltán, Zilahi Erika, Dankó Katalin

Megjegyzések:Idiopathic inflammatory myopathies are autoimmune diseases characterized by symmetrical proximal muscle weakness. Our aim was to identify a correlation between VDR polymorphisms or haplotypes and myositis. We studied VDR-BsmI, VDR-ApaI, VDR-TaqI, and VDR-FokI polymorphisms and haplotypes in 89 Hungarian poly-/dermatomyositis patients (69 females) and 93 controls (52 females). We did not obtain any significant differences for VDR-FokI, BsmI, ApaI, and TaqI genotypes and allele frequencies between patients withmyositis and healthy individuals. There was no association of VDR polymorphisms with clinical manifestations and laboratory profiles inmyositis patients. Menwithmyositis had a significantly different distribution of BB, Bb, and bb genotypes than female patients, control male individuals, and the entire control group. Distribution of TT, Tt, and tt genotypes was significantly different inmales than in females in patient group. According to four-marker haplotype prevalence, frequencies of sixteen possible haplotypes showed significant differences between patient and control groups. The three most frequent haplotypes in patients were the fbAt, FBaT, and fbAT. Our findings may reveal that there is a significant association: Bb and Tt genotypes can be associated with myositis in the Hungarian population we studied. We underline the importance of our result in the estimated prevalence of four-marker haplotypes

Cím:Does the Adult Human Ciliary Body Epithelium Contain "True" Retinal Stem Cells? / Froen Rebecca, Johnsen Erik O., Nicolaissen Bjorn, Facskó Andrea, Petrovski Goran, Moe Morten C.
Dátum:2013
ISSN:2314-6133 2314-6141
Megjegyzések:Recent reports of retinal stem cells being present in several locations of the adult eye have sparked great hopes that they may be used to treat the millions of people worldwide who suffer from blindness as a result of retinal disease or injury. A population of proliferative cells derived from the ciliary body epithelium (CE) has been considered one of the prime stem cell candidates, and as such they have received much attention in recent years. However, the true nature of these cells in the adult human eye has still not been fully elucidated, and the stem cell claim has become increasingly controversial in light of new and conflicting reports. In this paper, we will try to answer the question of whether the available evidence is strong enough for the research community to conclude that the adult human CE indeed harbors stem cells.

Cím:Tyrosine kinase inhibitor Imatinib mesylate alters DMBA-induced early onco/suppressor-gene expression with tissue-specificity in mice / Péter Attila Gergely, Balázs Murnyák, János Bencze, Andrea Kurucz, Timea Varjas, Katalin Gombos, Tibor Hortobágyi
Dátum:2019

Megjegyzések:Tyrosine kinases play crucial roles in cellular development and tumorigenesis. Tyrosine kinase inhibitors (TKIs) are effective and widely-used drug molecules in targeted cancer therapies. Altered expressions of proto-oncogenes and tumor suppressor genes after DMBA (7,12- dimethylbenz[a]anthracene) treatment have been described as early markers of tumor induction, however their tissue-specific effects remain still unclear. Our study was aimed to examine the short-term possible anti-neoplastic and chemo-preventive effects of a TKI compound (imatinib mesylate) on a DMBA-induced mouse tumor model. In addition, we also investigated the tissue specific expressions of Hras, Kras, Myc, Trp53 genes in the brain, bone marrow, spleen, liver, abdominal lymph nodes, thymus, lungs and kidneys, respectively. 24 hours after the imatinib mesylate injection, we observed significant Kras down-regulations in the bone marrow and lung of the DMBA-treated mice. Moreover, the mRNA expression of Myc was also found to be decreased significantly in the spleen. Interestingly, while Trp53 expression was significantly increased in the lung, it was decreased in the other tissues. However, there was also a tendency in the decreased Myc level in the bone marrow, brain, kidneys, lungs, lymph nodes, and in the decreased Hras level in the bone marrow, kidneys and lungs, although no significant differences were observed. Our findings indicate rapid tissue-specific impact of imatinib mesylate on DMBA-induced gene expression in vivo, supporting the chemo-preventive potential of imatinib mesylate in cancer.

Megjegyzések:The aim of this study was to investigate the effect of the serine/threonine protein phosphatase inhibitor, calyculin-A (CLA) on clot formation and on the procoagulant activity of human platelets. Platelet rich plasma (PRP) samples were preincubated with buffer or CLA and subsequently platelets were activated by the protease-activated receptor 1 (PAR-1) activator, thrombin-receptor activating peptide (TRAP). Clot retraction was detected by observing clot morphology up to 1 hour, phosphatidylserine (PS)-expression was studied by flow cytometry and thrombin generation was measured by a fluorimetric assay. For the intracellular Ca2+ assay, platelets were loaded with calcium-indicator dyes and the measurements were carried out using a ratiometric method with real-time confocal microscopy. CLA preincubation inhibited clot retraction, PS-expression and thrombin formation. TRAP activation elicited Ca2+ response and PS-expression in a subset of platelets. The activated PRP displayed significantly faster and enhanced thrombin generation compared to non-activated samples. CLA pretreatment abrogated PS-exposure and clot retraction also in TRAP-activated samples. As a consequence of the inhibitory effect on calcium elevation and PS-expression, CLA significantly downregulated thrombin generation in PRP. Our results show that CLA-pretreatment may be a useful tool to investigate platelet activation mechanisms that contribute to clot formation and thrombin generation.

Cím:The Interaction of Selectins and PSGL-1 as a Key Component in Thrombus Formation and Cancer Progression / János Kappelmayer, Béla Nagy Jr.
Dátum:2017
ISSN:2314-6133 2314-6141
Megjegyzések:Cellular interaction is inevitable in the pathomechanism of human disease. Formation of heterotypic cellular aggregates, between distinct cells of hematopoietic and non-hematopoietic origin, may be involved in events leading to inflammation and the complex process of cancer progression. Among adhesion receptors, the family of selectins with their ligands have been considered as one of the major contributors to cell-cell interactions. Consequently, the inhibition of the interplay between selectins and their ligands may have potential therapeutic benefits. In this review, we focus on the current evidence on the selectins as crucial modulators of inflammatory, thrombotic and malignant disorders. Knowing that there is promiscuity in selectin binding, we outline the importance of a key protein that serves as a ligand for all selectins. This dimeric mucin, the P-selectin glycoprotein ligand 1 (PSGL-1), has emerged as a major player in inflammation, thrombus and cancer development. We discuss the interaction of PSGL-1 with various selectins in physiological and pathological processes with particular emphasis on mechanisms that lead to severe disease.

Cím:In Vivo Molecular Imaging of the Efficacy of Aminopeptidase N (APN/CD13) Receptor Inhibitor Treatment on Experimental Tumors Using 68Ga-NODAGA-c(NGR) Peptide / Adrienn Kis, Noémi Dénes, Judit P. Szabó, Viktória Arató, Lívia Beke, Orsolya Matolay, Kata Nóra Enyedi, Gábor Méhes, Gábor Mező, Péter Bai, István Kertész, György Trencsényi

Megjegyzések:Introduction. The aminopeptidase N (APN/CD13) receptor plays an important role in the neoangiogenic process and metastatic tumor cell invasion. Clinical and preclinical studies reported that bestatin and actinonin are cytotoxic to APN/CD13-positive tumors and metastases due to their APN/CD13-specific inhibitor properties. Our previous studies have already shown that Ga-68-labeled NGR peptides bind specifically to APN/CD13 expressing tumor cells. The APN/CD13 specificity of Ga-68-NGR radiopharmaceuticals enables the following of the efficacy of antiangiogenic therapy with APN/CD13-specific inhibitors using positron emission tomography (PET). The aim of this in vivo study was to assess the antitumor effect of bestatin and actinonin treatment in subcutaneous transplanted HT1080 and B16-F10 tumor-bearing animal models using Ga-68-NODAGA-c(NGR). Materials and Methods. Three days after the inoculation of HT1080 and B16-F10 cells, mice were treated with intraperitoneal injection of bestatin (15 mg/kg) or actinonin (5 mg/kg) for 7 days. On the 5th and 10th day, in vivo PET scans and ex vivo biodistribution studies were performed 90 min after intravenous injection of 5.5 +/- 0.2 MBq(68)Ga-NODAGA-c(NGR). Results. Control-untreated HT1080 and B16-F10 tumors were clearly visualized by the APN/CD13-specific Ga-68-NODAGA-c(NGR) radiopharmaceutical. The western blot analysis also confirmed the strong APN/CDI3 positivity in the investigated tumors. We found significantly (p <= 0.05) lower radiopharmaceutical uptake after bestatin treatment and higher radiotracer accumulation in the actinonin-treated HT1080 tumors. In contrast, significantly lower (p <= 0.01) Ga-68-NODAGA-c(NGR) accumulation was observed in both bestatin- and actinonin-treated B16-F10 melanoma tumors compared to the untreated-control tumors. Bestatin inhibited tumor growth and Ga-68-NODAGA-c(NGR) uptake in both tumor models. Conclusion. The bestatin treatment is suitable for suppressing the neoangiogenic process and APN/CD13 expression of experimental HT1080 and B16-F10 tumors; furthermore, Ga-68-NODAGA-c(NGR) is an applicable radiotracer for the in vivo monitoring of the efficacy of the APN/CD13 inhibition-based anticancer therapies.

He/De tumor-bearing animals were anaesthetized, and 90 min after intravenous injection of10.2 +/- 1.1 MBq(68)Ga-NOTA-c(NGR) or(68)Ga-NODAGA-[c(RGD)](2)(as angiogenesis tracers) or(68)Ga-DOTA-nitroimidazole (for hypoxia imaging), whole-body PET/MRI scans were performed.Results. Hypoxic regions and angiogenic markers (alpha(v)beta(3)integrin and APN/CD13) were determined using(68)Ga-NOTA-c(NGR),Ga-68-DOTA-nitroimidazole, and(68)Ga-NODAGA-[c(RGD)](2)in subcutaneously growing He/De tumors in rats.Ga-68-NOTA-c(NGR) showed the strong APN/CD13 positivity of He/De tumorsin vivo, by which observation was confirmed by western blot analysis. By the qualitative analysis of PET images, heterogenous accumulation was found inside He/De tumors using all radiotracers. Significantly (p <= 0.01) higher SUVmean and SUVmax values were found in the radiotracer avid regions of the tumors than those of the nonavid areas using hypoxia and angiogenesis-specific radiopharmaceuticals. Furthermore, a strong correlation was found between the presence of angiogenic markers, the appearance of hypoxic regions, and the tumor volume using noninvasivein vivoPET imaging.Conclusion.Ga-68-DOTA-nitroimidazole and(68)Ga-NOTA-c(NGR) are suitable diagnostic radiotracers for the detection of the temporal changes of hypoxic areas and neoangiogenic molecule (CD13) expression, which vary during tumor growth in a hepatocellular carcinoma model.

Megjegyzések:Fenugreek is known since ancient times as a traditional herbal medicine of its multiple beneficial effects. Fenugreek's most studied and employed effect is its hypoglycemic property, but it can also be useful for the treatment of certain thyroid disorders or for the treatment of anorexia. The regulation of glucose homeostasis is a complex mechanism, dependent on the interaction of different types of hormones and neurotransmitters or other compounds. For the study of how diosgenin and fenugreek seeds modify insulin sensitivity, we used a rat insulin resistance model induced by high-fat diet. Diosgenin in three different doses (1mg/bwkg, 10mg/bwkg, and 50mg/bwkg, respectively) and fenugreek seed (0.2 g/bwkg)were administered orally for 6weeks. Insulin sensitivity was determined by hyperinsulinemic euglycemic glucose clamp method. Our research group found that although glucose infusion rate was not significantly modified in either group, the increased insulin sensitivity index and high metabolic clearance rate of insulin found in the 1 mg/kg diosgenin and the fenugreek seed treated group suggested an improved peripheral insulin sensitivity. Results from the 10 mg/kg diosgenin group, however, suggest a marked insulin resistance. Fenugreek seed therapy results on the investigated anabolic hormones support the theory that, besides insulin and gastrointestinal peptides, the hypothalamichypopituitary axis regulated hormones synchronized action with IGF-1 also play an important role in the maintaining of normal glucose levels. Both diosgenin and fenugreek seeds are capable of interacting with substrates of the above-mentioned regulatory mechanisms, inducing serious hormonal disorders. Moreover, fenugreek seeds showed the ability to reduce the thyroid hormone levels at the periphery and to modify the T4/T3 ratio. It means that in healthy people this effect could be considered a severe side effect; however, in hypothyroidism this effect represents a possibility of alternative natural therapy.
