However, the specific role of 5hmC in osteosarcoma (OS) remains largely unexplored. The-re-fore, this study aimed to investigate the function of 5hmC and TET3 in OS. In this study, we found a decreased total level of 5hmC in OS tissues. The expression of the TET3 protein was also decreased in OS. Importantly, the decreased levels of TET3 were associated with a decreased disease-free survival (DFS) rate in patients. To investigate the role of TET3 and 5hmC in OS, we manipulated the levels of TET3 in MG-63 cells. Silencing TET3 in these cells resulted in a twofold increase in proliferation. Additio-nally, the level of 5hmC decreased in these cells. Con-versely, over-expression of TET3 in MG-63 cells led to the expected inhibition of proliferation and invasion, accompanied by an increase in 5hmC levels. In conclusion, both 5hmC and TET3 protein levels were decreased in OS. Additionally, the over-expression of TET3 inhibited the proliferation of MG-63 cells, while the suppression of TET3 had the opposite effect. These findings suggest that decreased levels of 5hmC and TET3 may serve as potential markers for OS.</p>","PeriodicalId":12281,"journal":{"name":"Folia Biologica","volume":"70 2","pages":"113-122"},"PeriodicalIF":1.1,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142132279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explored the specific mechanisms underlying the impact of reactive oxygen species (ROS) on the Th17/Treg balance in CPP. The levels of ROS and the differentiation ratio of Th17/Treg in the peripheral blood of healthy individuals and CPP patients were measured using ELISA and flow cytometry, respectively. The association between the ROS levels and Th17/Treg was assessed using Pearson correlation analysis. The ROS levels and the Th17/Treg ratio were measured in CD4+ T cells following H2O2 treatment and NLRP3 inhibition. The effects of H2O2 treatment and NLRP3 inhibition on the NLRP3/IL-1β/caspase-1 pathway were observed using immunoblotting. Compared to the healthy group, the CPP group exhibited increased levels of ROS in the peripheral blood, an elevated ratio of Th17 differentiation, and a decreased ratio of Treg differentiation. ROS levels were positively correlated with the Th17 cell proportion but negatively correlated with the Treg cell proportion. The ROS levels and NLRP3/IL-1β/caspase-1 expression were up-regulated in CD4+ T cells after H2O2 treatment. Furthermore, there was an increase in Th17 differentiation and a decrease in Treg differentiation. Conversely, the NLRP3/IL-1β/caspase-1 pathway inhibition reversed the effects of H2O2 treatment, with no significant change in the ROS levels.

The first volume was published in Prague in 1954 on behalf of the Institute of Molecular Genetics of the Czechoslovak Academy of Sciences (since 1990 the Academy of Sciences of the Czech Republic) under the subtitle \"International edition of the journal Czechoslovakian Biology\". Born in the dark days of the Cold War, Folia Biologica provided a thin but important link between the politically controlled science behind the Iron Curtain in the former Czechoslovakia and that of the free Western world. Initially, the journal focused on research papers in the fields of experimental medicine, immunology, virology, and experimental zoology. Since 1961 (Volume 7), Folia Biologica has been indexed in the Web of Science database. The first issue of Volume 7 was introduced by a review article by Peter Brian Medawar (1915-1987), winner of the 1960 Nobel Prize in Physiology or Medicine \"for the discovery of acquired immunological tolerance\", which is reprinted in this anniversary issue [1].In the late 1960s, during the political relaxation that culminated in the Prague Spring, cooperation with free Western science intensified and enabled a lively scientific dialogue between Czechoslovak and foreign biological scientists, namely immunologists, molecular biologists, and virologists, as illustrated by a series of original research articles from Folia Biologica by Georg Davis Snell (1903-1996) and Jean Dausset (1916-2009), who were awarded the Nobel Prize in Physiology and Medicine in 1980 \"for their discoveries concerning genetically determined structures on the cell surface that regulate immunological reactions\", which led to the discovery of the major histocompatibility system (MHC) [2-7]. Another powerful example is an article in Folia Biologica by François Jacob (1920-2013), who was awarded the Nobel Prize in 1965 for discoveries that helped elucidate the transcriptional control of enzyme levels [8].Despite the years of political repression during the \"normalization\" period following the invasion of the Warsaw Pact troops into Czechoslovakia in 1968, the scientists and editors of Folia Biologica from the Academy of Sciences were able to maintain vibrant contacts with the world's leading scientists. In 1981, the journal changed its subtitle to \"Journal of Cellular and Molecular Biology\". In 1983, Folia Biologica published the article by Renato Dulbecco (1914-2012), who was awarded the Nobel Prize in 1975 for \"discoveries concerning the interaction between tumor viruses and the genetic material of the cell\"[9].With further orientation towards human molecular medicine, the journal entered the era after the Velvet Revolution in 1989, which represented the desired end of political control over national science.

In this study, we aimed to explore the role of LIG1 and post-transcripional regulators in NSCLC. Utilizing bioinformatic tools and qRT-PCR, our investigation substantiated the up-regulation of LIG1 within NSCLC cell lines and tumour tissues. Remarkably, individuals exhibiting elevated levels of LIG1 had diminished survival rates. Functionally, the depletion of LIG1 inhibited cell proliferation and migration, contrasting with the increased proliferation and migration upon LIG1 over-expression. Prediction from the TargetScanHuman database and results of dual luciferase reporter assays indicated that miR-325 could directly bind to and negatively regulate LIG1. Moreover, our findings demonstrated that the mimicry of miR-325 decreased cell viability, whereas its inhibition correspondingly increased viability, indicative of the tumour-suppressive role of miR-325 through the down-regulation of LIG1. Collectively, our findings show that LIG1 could promote tumour progression and knockdown of LIG1 could exert suppressive effects on NSCLC. As the post-transcriptional factor of LIG1, miR-325 could negatively regulate the expression of LIG1 to inhibit tumour progression in vitro.
