DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Study highlights increase in VZV-induced CNS infections and dementia risk

Researchers from Fujita Health University, Japan, observed a rise in adult central nervous system (CNS) infections, primarily aseptic meningitis caused by the varicella zoster virus (VZV), post-2019. The researchers highlighted the potential of zoster vaccination to reduce CNS infections.

Study challenges role of BRCA1 mutation in prostate cancer initiation

Mutations in the BRCA1 gene that are either inherited (germline) or acquired (somatic) might not be key to the initiation of prostate cancer, as previously thought, suggests the first study of its kind, published online in the open access journal BMJ Oncology.

Study unravels the complex interplay of the UPS in cancer development and treatment

A new review published in Genes & Diseases explores the pivotal role of the ubiquitin-proteasome system (UPS) in regulating the tumor microenvironment (TME) and driving cancer progression. The study provides novel insights into how ubiquitination and deubiquitination impact tumor cells, immune responses, and potential therapeutic strategies for cancer treatment.
