Human Polyomavirus BK Genome Analysis in BKPyV Induced Rodent Cell Lines

MicrobiologyOpen, Volume 14, Issue 5, October 2025.
In this study, we analyzed the BK polyomavirus (BKPyV) genome derived from three rodent cell lines established from BKPyV induced tumors. BKPyV derived one cell line had a large deletion. The noncoding control region (NCCR) of BKPyV derived from these cell lines had the same structure as viruses induced tumors.

Manganese Neurotoxicity and Familial Disorders of Manganese Transport

Annals of the Child Neurology Society, Volume 3, Issue 3, Page 135-144, September 2025.
ABSTRACT Manganese is the 12th most common element in the Earth's crust and is an essential industrial component. Biologically, this metal plays an important role as a constituent of numerous enzymes. While manganese is required for normal biochemical and physiological processes, manganese excess can lead to significant toxicity, particularly to the ...

Culture models to study leukocyte trafficking across the choroid plexus

Fluids and Barriers of the CNS, 2013
Background A critical point during the course of central nervous system infection is the influx of leukocytes from the blood into the brain across the blood-brain barrier (BBB) and the blood-cerebrospinal fluid barrier (BCSFB).

The TP53 tumor suppressor gene: From molecular biology to clinical investigations

Journal of Internal Medicine, Volume 298, Issue 2, Page 78-96, August 2025.
Abstract Extensively studied over the past four decades, the TP53 gene has emerged as a pivotal watchman in cellular defense and a key factor in cancer biology. TP53 is the most frequently mutated gene in human malignancies, 50% of which carry alterations to it.

Congenital Intracranial Tumors: Prenatal Diagnosis by Fetal Magnetic Resonance Imaging

iRADIOLOGY, Volume 3, Issue 3, Page 203-208, June 2025.
Fetal intracranial tumors are rare, comprising 0.5%–1.9% of all childhood tumors, with their true incidence potentially underestimated. This review highlights the role of fetal MRI, particularly with advanced sequences, in diagnosing common fetal brain tumors such as teratomas, astrocytomas, and choroid plexus papillomas, often presenting unique ...
