We investigated whether the methylation status of RASSF1A and p16 genes, alone or in combination with host and viral factors, affects the response to therapy with pegylated interferon/ribavirin (PEGIFN/ RBV). Methylation-specific polymerase chain reaction (MSP) was used to determine the methylation status of the target promoter sequences of RASSF1A and p16 in circulating-free DNA from the peripheral blood of 49 patients with CHC genotype 1b. The methylation status of the examined genes did not affect the response to therapy. However, the simultaneous presence of either RASSF1A or p16 methylation and the CC genotype of IL28B was significantly related to a sustained virologic response (P=0.009 and P=0.032, respectively). After Bonferroni correction, only the result concerning the RASSF1A gene remained significant (P<0.0125). Methylation of RASSF1A was associated with the CC genotype of the IL28B gene (P=0.024) and a higher viral load (?400 000 IU/mL, P=0.009). Our results suggest that combined analysis of RASSF1A gene methylation and IL28B rs12979860 polymorphism could potentially help in the prediction of therapy response in CHC genotype 1b patients.","PeriodicalId":8145,"journal":{"name":"Archives of Biological Sciences","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68389951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The diversity changes of cyanobacteria in waters intended for human consumption in Serbia were analyzed two decades after the first floristic study was published. The examination included phytoplankton and phytobenthic sample analysis from 35 localities in the period between 2012 and 2017, together with published literature records. The results indicate that the number of identified taxa doubled since the first Serbian Flora of Cyanobacteria was released two decades ago. The changes most likely occurred due to environmental factors, including hydrological transformations of habitats, cultural eutrophication and global warming. Many frequently recorded taxa are potentially toxic and bloom-forming. The spread of alien species with potentially invasive characteristics has also been noted. Canonical correspondence analysis (CCA) indicates that shallow waterbodies are the most vulnerable regarding the occurrence and expansion of bloom-forming, potentially toxic and invasive taxa. This shows the urgent need for a more detailed investigation. Additionally, although most of the research was focused on planktonic forms, benthic cyanobacteria represent an important component for public health risk assessment and therefore should be more frequently investigated.","PeriodicalId":8145,"journal":{"name":"Archives of Biological Sciences","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68390200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polyamine levels and arginase activity were significantly increased in cancer and adjacent tissue specimens compared to healthy ones, while the level of NO2+NO3 was significantly lower in cancer compared to both adjacent and healthy tissues. The high polyamine content in the adjacent colonic mucosa indicates a high proliferative potential of tumor-adjacent tissue. Although we found individual correlations indicating the possible prognostic value of arginase, the performed statistical analysis did not show a predictive significance of arginase activity in the examined tissue specimens for five-year survival of the patients.

Soluble Fas, TRAIL, tissue-type plasminogen activator (tPA), plasminogen activator inhibitor-1 (PAI-1), D-dimers and lactate dehydrogenase (LD) levels were measured.

Malignant effusion was 1.6-fold more prevalent in patients with elevated Fas than in those without (48.5% vs 30.4%, P=0.031). The P/B ratio of tPA was 2.5-fold higher in malignant effusion than in non-malignant effusion (4.65 vs 1.83, P<0.001). Fas was positively correlated with tPA and D-dimers, but not with biochemical parameters. The ability of Fas to identify malignant effusions was significantly greater than those of tPA and LD.

An HPLC-based method was used to obtain confirmatory data. Montivipera raddei venom predominantly cleaved the A? chain of fibrinogen in a time-dependent manner. A very slight decrease in band intensity of the B? chain was observable after a longer incubation time. Cleavage of fibrinogen was confirmed by HPLC. Zymography revealed that the venom contained 50 and 75 kDa fibrinogenolytic enzymes. Ethylenediaminetetraacetic acid (EDTA) and 1,10-phenanthroline inhibited the overall fibrinogenolytic activity, while phenylmethylsulfonyl fluoride (PMSF) and aprotinin only inhibited the degradation of the B? chain. These results indicated that metalloproteinases were major fibrinogenolytic enzymes in the venom. An inhibitor study suggested the presence of serine proteinases that broke down the B? chain. With this study, the fibrinogenolytic activity of M. raddei venom was shown for the first time.
