Transcriptome profiling of Canine Parvovirus 2 Nonstructural gene 1(CPV2.NS1) transfected 4T1 mice mammary tumor cells to elucidate its oncolytic effects.

Oncolytic viral gene therapy is a directed approach to target cancer cells without affecting healthy cells of the body. Canine parvovirus (CPV2) is an oncolytic virus that precisely targets and destroys neoplastic cells by causing DNA damage, mitochondrial damage, and apoptosis. Non-structural gene 1 (NS1) of CPV, concerned with viral DNA replication is a key mediator of cytotoxicity of CPV and can specifically cause tumor cell lysis.

Genome-wide DNA methylation profiles regulate distinct heat stress response in zebu (Bos indicus) and crossbred (Bos indicus × Bos taurus) cattle.

Epigenetic variations result from long-term adaptation to environmental factors. The Bos indicus (zebu) adapted to tropical conditions, whereas Bos taurus adapted to temperate conditions; hence native zebu cattle and its crossbred (B indicus × B taurus) show differences in responses to heat stress. The present study evaluated genome-wide DNA methylation profiles of these two breeds of cattle that may explain distinct heat stress responses.

The present study explored the expression of lncRNA, circRNA and their functions in PPRV infected B-lymphocyte (B95a) cells.

Genome-wide transcriptome profiling of CSF virus challenged monocyte-derived macrophages provides distinct insights into immune response of Landrace and indigenous Ghurrah pigs.

The present study was undertaken to characterize the distinct immune response in indigenous Ghurrah and exotic Landrace pigs by challenging monocyte-derived macrophages (MDMs) with CSF virus under in-vitro conditions and assessing the variations in the transcriptome profile at 48 h post-infection (hpi). RNA-sequencing was carried out in infected and non-infected MDMs of Ghurrah (n = 3) and Landrace (n = 3) piglets prior- as well as post-stimulation. MDMs of Ghurrah showed greater immune regulation in response to CSF infection with 518 significantly differentially expressed genes (DEG) in infected versus non-infected MDMs, as compared to only 31 DEGs in Landrace MDMs.

Effect of acute heat shock on stress gene expression and DNA methylation in zebu (Bos indicus) and crossbred (Bos indicus × Bos taurus) dairy cattle.

Environmental temperature is one of the major factors to affect health and productivity of dairy cattle. Gene expression networks within the cells and tissues coordinate stress response, metabolism, and milk production in dairy cattle. Epigenetic DNA methylations were found to mediate the effect of environment by regulating gene expression patterns.

Differential expression of long non-coding RNAs under (PPRV) infection in goats.

(PPR) characterized by fever, sore mouth, conjunctivitis, gastroenteritis, and pneumonia, is an acute, highly contagious viral disease of sheep and goats. The role of long non-coding RNAs (lncRNAs) in PPRV infection has not been explored to date. In this study, the transcriptome profiles of virulent Peste des petits ruminants virus (PPRV) infected goat tissues - lung and spleen were analyzed to identify the role of lncRNAs in PPRV infection.

Novel peptide (RATH) mediated delivery of peptide nucleic acids for antiviral interventions.

The peptide nucleic acid (PNA) is a chimeric molecule with the nucleobases connected by peptide bonds. This chimeric nature gives the PNA certain therapeutic advantages over natural antisense nucleic acid molecules. The PNA probes are known for its better and stronger complementation with target nucleic acids.

Cross-talk between energy metabolism and epigenetics during temperature stress response in C2C12 myoblasts.

Environmental stress induces disturbances in cell energy metabolism and may cause epigenetic modifications. This study aimed to understand the possible impact of temperature stress (35 °C, 39 °C and 41 °C, compared to control 37 °C) on energy metabolism and epigenetic modifications, such as DNA methylation and histone H4 acetylation, as well as its effects on the expression of genes responsible for epigenetic changes, in mouse skeletal myoblasts (C2C12 cells). The results showed significantly reduced maximal respiration and spare respiratory capacity under heat stress (39 °C and 41 °C), suggesting that mitochondrial functions were compromised under these conditions.
