DNA Virus Detection in Olfactory Neuroblastomas Using Targeted Enrichment NGS

open access: yesNeuropathology, Volume 46, Issue 2, April 2026.
ABSTRACT A variety of malignancies can be found in the sinonasal tract including the nasal cavity, paranasal sinuses, and skull base. Many of these are attributed to viruses, for example, carcinomas with the presence of transcriptionally active high‐risk human papillomavirus, as well as Epstein–Barr virus associated malignant lymphoepithelial carcinoma

Simian Virus 40 and Protein Transfer

open access: yes, 2015
Protein transfer to solid supports after polyacrylamide gel electrophoresis, and subsequent probing with specific antibodies, is one of the most important tools in modern molecular and cellular biology. Since its development in 1979, the improvement of the technique has been impressive, from new apparatus to streamline the electrophoresis step to ...

Fra-1 governs cell migration via modulation of CD44 expression in human mesotheliomas

open access: yesMolecular Cancer, 2007
Silencing of Fra-1, a component of the dimeric transcription factor, activator protein-1 (AP-1), inhibits mRNA expression of c-met and cd44 in rat mesothelioma cells and is causally linked to maintenance of the transformed phenotype.

HLA-Associated viral mutations are common in human immunodeficiency virus type 1 elite controllers [PDF]

open access: yes, 2009
Elite controllers (EC) of human immunodeficiency virus type 1 (HTV-1) maintain viremia below the limit of detection without antiretroviral treatment. Virus-specific cytotoxic CD8+ T lymphocytes are believed to play a crucial role in viral containment ...

Successful Retroviral Gene Transfer of Simian Virus 40 T Antigen and Herpes Simplex Virus-Thymidine Kinase into Human Hepatocytes

open access: yesCell Transplantation, 2001
Current clinical reports have indicated that hepatocyte transplantation (HTX) could be used in patients with liver failure and in children with liver-based metabolic diseases. One of the major limiting factors of HTX is a serious shortage of donor livers

Checkpoint inhibitor blockade and epigenetic reprogrammability in CD8 T-cell activation and exhaustion

open access: yesTherapeutic Advances in Vaccines and Immunotherapy, 2020
CD8 + T-cell exhaustion is a dysfunctional state that is regulated through the expression of inhibitory checkpoint receptor genes including the cytotoxic T-lymphocyte–associated antigen 4, programmed death 1, and DNA methylation of effector genes ...

The Fusion Activity of HIV-1 gp41 Depends on Interhelical Interactions [PDF]

open access: yes, 2005
Infection by human immunodeficiency virus type I requires the fusogenic activity of gp41, the transmembrane subunit of the viral envelope protein. Crystallographic studies have revealed that fusion-active gp41 is a "trimer-of-hairpins" in which three ...
