The role of human endogenous retroviruses in gliomas: from etiological perspectives and therapeutic implications.

Ashish H Shah, Mark Gilbert, Michael E Ivan, Ricardo J Komotar, John Heiss, Avindra Nath,

Accounting for approximately 8% of the human genome, human endogenous retroviruses (HERVs) have been implicated in a variety of cancers including gliomas. In normal cells, tight epigenetic regulation of HERVs prevent aberrant expression; however, in cancer cells, HERVs expression remains pervasive, suggesting a role of HERVs in oncogenic transformation. HERVs ... Read more >>

Prospective Evaluation of an Abbreviated Test Battery to Screen for Neurocognitive Impairment in HIV-Positive Military Members.

Brian K Agan, Seung Hyun Won, Anuradha Ganesan, Bryan R Smith, Camille Estupigan, Ryan Maves, Gregory Utz, Hsing-Chuan Hsieh, Edmund Tramont, Avindra Nath, Joseph Snow,

Human immunodeficiency virus (HIV)-associated neurocognitive disorder (HAND) affects around 20-50% of people living with HIV (PLWH). Although batteries of tests are used to identify neurocognitive impairment (NCI), they are long and difficult to perform during a routine clinic visit, thus impairing the ability to diagnose HAND. Therefore, a brief yet ... Read more >>
