Abstract Ochratoxin A (OTA) is a well-known mycotoxin that adversely affects different human cells. Inhalational exposure to OTA and subsequent pulmonary diseases have been previously reported, yet its potential carcinogenicity underlying molecular mechanisms not fully elucidated. This study aimed evaluate the OTA-induced cytotoxicity epigenetic changes in fetal lung fibroblast (WI-38) was assessed by MTT assay; RT-qPCR used determine expression of BAX , BCL-2 TP53 miR-155 while ELISA for measuring 5-methyl cytosine percentage assess global DNA methylation OTA-treated versus control WI-38 cells demonstrated sensitivity with IC50 at 22.38 μM. Though Bcl-2 were downregulated, low / ratio, upregulated, their fold showed decline trend increasing concentration. significant dose-dependent upregulation observed, dynamic time-related decline. Using subtoxic concentrations, hypermethylation alterations identified.

MicroRNAs (miRs) are a group of small, 17–25 nucleotide, non-coding RNA that regulate gene expression at the post-transcriptional level. To date, little is known about molecular signatures regulatory interactions between miRs and apoptosis oxidative stress in viral diseases. Lagovirus europaeus virus causes severe disease rabbits ( Oryctolagus cuniculus ) called Rabbit Hemorrhagic Disease (RHD) belongs to Caliciviridae family, genus. Within associated with RHD, two genotypes (GI.1 GI.2) have been distinguished, GI.1 genotype includes four variants (GI.1a, GI.1b, GI.1c, GI.1d). The study aimed assess their target genes involved stress, as well potential impact on pathways during —two infection different virulences tissues (liver, lung, kidneys, spleen). related was determined using quantitative real-time PCR (qPCR). In this study, we evaluated miR-21 PTEN , PDCD4 ), miR-16b Bcl-2 CXCL10 miR-34a p53 SIRT1 miRs—related stress—miR-122 Bach1 miR-132 Nfr-2 ).

Rabbit Haemorrhagic Disease (RHD), also known as Viral (RVHD), is a highly contagious and often fatal viral disease that affects domestic wild rabbits. It's caused by two related viruses: Virus (RHDV) 2 (RHDV2). The endemic in many European, Asian American countries, but the agent still recognized an emergent infection, associated with mass losses extremely high mortality rabbits of all breeds. One Health Scientific Research Institute, PSI collaboration SRI ‘Veterinary Biotechnologies’, LLC developed house PCR-based protocol for RHDV detection RHDV-2 differentiation, requires fast implementation. This diagnostics kit evaluation described under OIE requirements determination sensitivity, specificity, repeatability domain-specificity. Detection recommended practical application.

MicroRNAs (miR) are a group of small, non-coding RNAs 17-25 nucleotides that regulate gene expression at the post-transcriptional level. Dysregulation miRNA or function may contribute to abnormal and signaling pathways, leading disease pathology. Lagovirus europaeus (L. europaeus) causes severe in rabbits called rabbit hemorrhagic (RHD). The symptoms liver, lung, kidney, spleen degeneration observed during RHD similar those acute liver failure (ALF) multi-organ (MOF) humans. In this study, we assessed miRs their target genes involved innate immune inflammatory response. Also, potential impact on pathways L. infection-two genotypes (GI.1 GI.2)-in lungs, kidneys, spleen. was determined using quantitative real-time PCR (qPCR). We miR-155 (MyD88, TAB2, p65, NLRP3), miR-146a (IRAK1, TRAF6), miR-223 (TLR4, IKKα, miR-125b (MyD88). also examined biomarkers inflammation: IL-1β, IL-6, TNF-α, IL-18 four tissues mRNA Our study shows main regulators response europaeus/GI.1 GI.2 infection, as well RHD, miR-155, miR-223, miR-146a.
