Epigenetic and gene therapy in human and veterinary medicine.

Gene therapy is a focus of interest in both human and veterinary medicine, especially in recent years due to the potential applications of CRISPR/Cas9 technology. Another relatively new approach is that of epigenetic therapy, which involves an intervention based on epigenetic marks, including DNA methylation, histone post-translational modifications, and post-transcription modifications of distinct RNAs. The epigenome results from enzymatic reactions, which regulate gene expression without altering DNA sequences.

RNA-related DNA damage and repair: The role of N7-methylguanosine in the cell nucleus exposed to UV light.

Background: Chemical modifications in mRNAs, tRNAs, rRNAs, and non-coding RNAs stabilize these nucleic acids and regulate their function. In addition to regulating the translation of genetic information from mRNA to proteins, it has been revealed that modifications in RNAs regulate repair processes in the genome.

Methods: Using local laser microirradiation, confocal microscopy, dot blots, and mass spectrometry we studied the role of N7-methylguanosine (m7G), which is co-transcriptionally installed in RNA.

First detection of Africa 4 lineage in a population of carnivores from South Africa.

Molecular Detection of , and spp. in Vespertilionid Bats from Central Europe.

Bats may carry various viruses and bacteria which can be harmful to humans, but little is known about their role as a parasitic source with zoonotic potential. The aim of this study was to test wild bats for the presence of selected parasites: , and microsporidia spp. In total, brain and small intestine tissues of 100 bats (52 , 43 and 5 ) were used for the DNA isolation and PCR detection of the abovementioned agents.

PARP-dependent and NAT10-independent acetylation of N4-cytidine in RNA appears in UV-damaged chromatin.

RNA modifications have been known for many years, but their function has not been fully elucidated yet. For instance, the regulatory role of acetylation on N4-cytidine (ac4C) in RNA can be explored not only in terms of RNA stability and mRNA translation but also in DNA repair. Here, we observe a high level of ac4C RNA at DNA lesions in interphase cells and irradiated cells in telophase.

Early recruitment of PARP-dependent mA RNA methylation at DNA lesions is subsequently accompanied by active DNA demethylation.

RNA methylation, especially 6-methyladenosine (mA)-modified RNAs, plays a specific role in DNA damage response (DDR). Here, we also observe that RNA modified at 8-methyladenosine (mA) is recruited to UVA-damaged chromatin immediately after microirradiation. Interestingly, the level of mA RNA at genomic lesions was reduced after inhibition of histone deacetylases and DNA methyltransferases.

Irradiation potentiates p53 phosphorylation and p53 binding to the promoter and coding region of the TP53 gene.

An essential factor of the DNA damage response is 53BP1, a multimeric protein that inhibits the resection-dependent double-strand break (DBS) repair. The p53 protein is a tumor suppressor known as a guardian of the genome. Although the interaction between 53BP1 and its p53 partner is well-known in regulating gene expression, a question remains whether genome injury can affect the interaction between 53BP1 and p53 proteins or p53 binding to DNA.

Validation of Medicinal Leeches () as a Non-invasive Blood Sampling Tool for Hematology and Biochemistry Profiling in Mammals.

Blood sampling is a challenging procedure in many captive animals. Although manual restraint or anesthesia are usually possible, they entail intense stress and a high risk of injuries or organ failure. Blood sampling using medicinal leeches () represents a promising non-invasive alternative to venipuncture; however, leech blood meal was to date used only for qualitative analyses such as genetic or serological screenings.

Localization of METTL16 at the Nuclear Periphery and the Nucleolus Is Cell Cycle-Specific and METTL16 Interacts with Several Nucleolar Proteins.

METTL16 methyltransferase is responsible for the methylation of N-adenosine (mA) in several RNAs. In mouse cells, we showed that the nuclear distribution of METTL16 is cell cycle-specific. In the G1/S phases, METTL16 accumulates to the nucleolus, while in the G2 phase, the level of METTL16 increases in the nucleoplasm.
