Computational analysis of MYC gene variants: structural and functional impact of non-synonymous SNPs.

The MYC proto-oncogene encodes a basic helix-loop-helix leucine zipper (HLH-LZ) transcription factor, acting as a master regulator of genes involved in cellular proliferation, differentiation, and immune surveillance. Dysregulation of MYC is implicated in over 70% of human cancers, driving oncogenic processes through altered gene expression and disrupted cellular functions. Non-synonymous single nucleotide polymorphisms (nsSNPs) within coding regions can significantly impact protein structure and function, leading to abnormal cellular behaviours.

Newcastle Disease Virus Expressing Cap Gene of Porcine Circovirus Type 2 Confers Protection in Mice and Induced Long-Lasting Neutralizing Antibodies in Pigs.

: Porcine Circovirus 2 (PCV2) infection poses significant health and economic challenges to the global swine industry. The disease in pigs leads to lymphoid depletion, resulting in immunosuppression and increased susceptibility to co-infections with other bacterial and viral pathogens. This study evaluated the efficacy of two novel recombinant Newcastle disease virus (NDV) strain R2B vectored vaccines that express the cap gene of PCV2 alone and along with the transmembrane and cytoplasmic tail (TMCT) domains of the NDV F gene.

Modulatory Role of Pantropic Cell Signaling Pathways in the Antimigratory and Antiproliferative Action of Triazole Chelated Iridium(III) Complexes in Cervical Cancer Cells.

In the current study, the antimigratory and antiproliferative effect of three substituted triazole-chelated iridium(III) complexes Ir-TRN, Ir-TRH, and Ir-TRF were studied with special emphasis on modulation of P53 activity, a cell cycle regulator. ERK2/MAPK, another crucial cell signaling pathway protein, was also shown to play a crucial role in cell migration and proliferation. The complexes increase the ROS generation within the cell, further supporting apoptotic induction by exerting cellular oxidative stress.

Neurotropic Murine β-Coronavirus Infection Causes Differential Expression of Connexin 47 in Oligodendrocyte Subpopulations Associated with Demyelination.

Gap junctions (GJs) play a crucial role in the survival of oligodendrocytes and myelination of the central nervous system (CNS). In this study, we investigated the spatiotemporal changes in the expression of oligodendroglial GJ protein connexin 47 (Cx47), its primary astroglial coupling partner, Cx43, and their association with demyelination following intracerebral infection with mouse hepatitis virus (MHV). Neurotropic strains of MHV, a β-coronavirus, induce an acute encephalomyelitis followed by a chronic demyelinating disease that shares similarities with the human disease multiple sclerosis (MS).
