The ability of suspended primary OMECs to proliferate in vitro after cryopreservation was compared to that of OMEC cultures that had undergone the same process. Both were preserved in standard complex medium (COM) with or without cryoprotective agents (CPAs) (gly-cerol at 5 % or 10 % or dimethyl sulphoxide at 10 %). We found that after cryopreservation, primary OMECs could form a confluent cell sheet only in a few samples after 22 ± 2.9 (mean ± SD) days of cultivation with 72.4 % ± 12.9 % overall viability. Instead, all ex vivo OMEC cultures could re-expand after cryopreservation with a comparable viability of 78.6 ± 13.8 %, like primary OMECs, but with significantly faster growth rate (adj. P < 001), forming a confluent cell sheet at 13.7 ± 3.9 days. Gene expression analyses of the ex vivo expansion of OMEC cultures showed that the stemness, proliferation and differentiation-related gene expression was similar before and after cryopreservation, except for KRT13 expres-sion, which significantly decreased after the second passage (adj. P < 0.05). The addition of CPAs had no effect on these outcomes. In conclusion, the optimal strategy for OMEC preservation is to freeze the cells that have been previously cultured, in order to maintain cell viability and the capacity to create a sizable graft even without CPAs.","PeriodicalId":12281,"journal":{"name":"Folia Biologica","volume":"70 4","pages":"209-218"},"PeriodicalIF":1.1,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142846186","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}

A cohort of 135 patients with CSCC were enrolled, and tissue samples were collected for analysis. The expression of EMX2OS in the tissues was quantified by PCR, with its correlation to the clinicopathological features, and prognosis was evaluated by χ2, Kaplan-Meier and Cox regression analyses. The regulatory effects of EMX2OS on CSCC cells were investigated by CCK8 and Transwell assays, while the underlying molecular mechanisms were elucidated by luciferase reporter assays. Significant down-regulation of EMX2OS was observed in CSCC, correlating with advanced FIGO stages, poor differentiation and adverse prognosis of patients. Over-expression of EMX2OS significantly suppressed cell growth and metastasis in CSCC. Negative regulation of miR-574-5p by EMX2OS was observed, and over-expression of miR-574-5p alleviated the inhibition of CSCC cells by EMX2OS.

Diagnosis primarily relies on invasive endoscopy and monitoring of faecal calprotectin (FC), which has limitations, particularly regarding patient compliance. There is a pressing need for a new biomarker that is non-invasive, easily determinable, and possesses good diagnostic accuracy for both dia-gnosing and monitoring IBD. Our narrative review covers the latest developments in novel serum biomarkers, focusing on those with promising diagnostic accuracy and laboratory methods, and evaluates them in the context of established biomarkers such as FC and CRP. Serum calprotectin (SC) and leucine-rich alpha-2 glycoprotein (LRG) show the most extensive evidence and relatively good diagnostic accuracy but currently cannot replace FC due to insufficient evidence. Major limitations of the analysed studies include their monocentric nature, small sample sizes, lack of longitudinal monitoring and in some cases, missing assessments of endoscopic activity. ELISA holds a leading position among the laboratory methods; however, emerging evidence supports the potential use of point-of-care testing (POCT). Establishing these biomarkers for regular clinical application will require further validation through multicentric studies involving a larger number of patients with a longitudinal design, concurrent assessment of endoscopic activity and pro-active monitoring of the biomarker. However, based on the evidence accumulated so far, SC might potentially serve as a complementary biomarker and/or in assessing the activity of extraintestinal manifestations in IBD patients, while LRG appears to be effective in evaluating endoscopic activity, especially in small bowel CD.","PeriodicalId":12281,"journal":{"name":"Folia Biologica","volume":"70 5-6","pages":"248-261"},"PeriodicalIF":1.1,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143070839","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}

Lysosome-related differentially expressed genes (DEGs) were identified and used for molecular subtyping of MM patients. A prognostic model was constructed using univariate Cox regression and LASSO regression analyses. The relationship between prognostic genes, immune cell types, and autophagy pathways was assessed through correlation analysis. RT-qPCR was performed to validate the expression of prognostic genes in MM cells. A total of 9,954 DEGs were identified between high and low immune score groups, with 213 intersecting with lysosomal genes. Molecular subtyping revealed two distinct MM subtypes with significant differences in immune cell types and autophagy pathway activities. Five lysosome-related DEGs (CORO1A, ELANE, PSAP, RNASE2, and SNAPIN) were identified as significant prognostic markers. The prognostic model showed moderate predictive accuracy with AUC values up to 0.723. Prognostic genes demonstrated significant correlations with various immune cell types and autophagy pathways. Additionally, CORO1A, PSAP and RNASE2 expression was up-regulated in MM cells, while ELANE and SNAPIN were down-regulated. Five lysosomal genes in MM were identified, and a new risk model for prognosis was developed using these genes.

Its increasing use places high demands on correct sample identification, independent confirmation of prioritized variants, and their functional and clinical interpretation. To streamline these processes, we introduced parallel DNA and RNA capture-based NGS using identical capture panel CZECANCA, which is routinely used for DNA analysis of hereditary cancer predisposition. Here, we present the analytical workflow for RNA sample processing and its analytical and diagnostic performance. Parallel DNA/RNA analysis allowed credible sample identification by calculating the kinship coefficient. The RNA capture-based approach enriched transcriptional targets for the majority of clinically relevant cancer predisposition genes to a degree that allowed analysis of the effect of identified DNA variants on mRNA processing. By comparing the panel and whole-exome RNA enrichment, we demonstrated that the tissue-specific gene expression pattern is independent of the capture panel. Moreover, technical replicates confirmed high reproducibility of the tested RNA analysis. We concluded that parallel DNA/RNA NGS using the identical gene panel is a robust and cost-effective diagnostic strategy. In our setting, it allows routine analysis of 48 DNA/RNA pairs using NextSeq 500/550 Mid Output Kit v2.5 (150 cycles) in a single run with sufficient coverage to analyse 226 cancer predisposition and candidate ge-nes. This approach can replace laborious Sanger confirmatory sequencing, increase testing turnaround, reduce analysis costs, and improve interpretation of the impact of variants by analysing their effect on mRNA processing.","PeriodicalId":12281,"journal":{"name":"Folia Biologica","volume":"70 1","pages":"62-73"},"PeriodicalIF":0.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141237164","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}

Anaemia is a frequent adverse effect of anticancer treatment caused in part by eryptosis and haemolysis. Thus, it is important to investigate the role of DHA in red blood cell (RBC) death. RBCs were treated with anticancer concentrations (10-100 μM) of DHA under different physiological conditions, and fluorescence-assisted cell sorting was employed to measure eryptotic markers. Cell membrane scrambling was detected by annexin-V-FITC labelling, cytoplasmic Ca2+ by Fluo4/AM, cell size by forward scatter (FSC), and oxidative stress by H2DCFDA. Haemolytic markers were also assayed by photometric methods. DHA caused significant phospholipid scrambling with Ca2+ accumulation, loss of cellular volume, and oxidative stress. These changes were associated with dacrocyte formation, as revealed by electron microscopy. Moreover, DHA exhibited a dual effect on membrane integrity: it was haemolytic under isotonic conditions and anti-haemolytic in hypotonic environments. Importantly, inhibition of Rac1 GTPase activity with NSC23766 significantly reduced DHA-mediated haemolysis, as did co-administration of either sucrose or polyethylene glycol 8,000. Conversely, the presence of 125 mM KCl and urea without extracellular Ca2+ significantly exacerbated DHA toxicity. In conclusion, this is the first report that identifies key biochemical mechanisms underlying the cytotoxic effects of DHA in RBCs, promoting further development and validation of DHA in anticancer therapy.","PeriodicalId":12281,"journal":{"name":"Folia Biologica","volume":"70 3","pages":"179-188"},"PeriodicalIF":1.1,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142791469","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}

As the cell differentiation trajectory matured, we found that aneuploid osteoblasts first increased the inflammatory response activity and then enhanced the ability to activate T cells, whereas osteoclasts gradually enhanced the cellular energy metabolism, cell adhesion, cell proliferation and immune response; the activated biological functions were gradually weakened. The analysis by CellChat indicated that CTLA4 or TIGIT might act as important immune checkpoint genes to attenuate the inhibitory effect of aneuploid osteoclasts on NK/T cells, thereby enhancing the activity of NK/T cells.

Axial lengths were measured every two weeks, and the expression of Sp1 and Col-I in the sclera was assessed by immunohistochemistry, Western blot and RT-qPCR. After 4, 6, 8, 10, and 12 weeks of light exposure, the L and G groups showed considerably longer axial lengths than the N group, with the L group exhibiting significantly longer axial lengths compared with the E and F groups. The protein and mRNA expression levels of Sp1 and Col-I, ranked from highest to lowest, were as follows: N, E, F, G, and L. The expression of Sp1 and Col-I was positively correlated, but both were negatively correlated with the length of the eye axis. The E group demonstrated higher Sp1 and Col-I expression than the other artificial light groups. Artificial light with a continuous, full spectrum lacking peaks and valleys can inhibit the elongation of the eye axis in juvenile guinea pigs and has a protective effect against myopia.

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.

Therefore, the recent success of immune checkpoint inhibitors (ICIs) in cancer treatment motivated their clinical investigation in TCLs as well. Multiple studies showed promising results; however, cases of TCL hyperprogression following ICI treatment and secondary T-cell-derived malignancies associated with ICI treatment of other cancer types were also reported. In our review, we first briefly summarize classification of T-cell-derived malignancies, general anti-tumor immune response, immune evasion, and immune checkpoint signaling. Next, we provide an overview of immune checkpoint molecule deregulation in TCLs, summarize available studies of ICIs in TCLs, and review the above-mentioned safety concerns associa-ted with ICI treatment and T-cell-derived malignancies. Despite initial promising results, further studies are necessary to define the most suitable clinical applications and ICI therapeutic combinations with other novel treatment approaches within TCL treatment.
