The Discovery of Reverse Transcriptase.

open access: yesAnnual Review of Virology, 2016
In 1970 the independent and simultaneous discovery of reverse transcriptase in retroviruses (then RNA tumor viruses) by David Baltimore and Howard Temin revolutionized molecular biology and laid the foundations for retrovirology and cancer biology.

Telomerase reverse transcriptase and neurodegenerative diseases

open access: yesFrontiers in Immunology, 2023
Neurodegenerative diseases (NDs) are chronic conditions that result in progressive damage to the nervous system, including Alzheimer’s disease (AD), Parkinson’s disease (PD), Huntington’s disease (HD), and Amyotrophic lateral sclerosis (ALS).

Viral reverse transcriptases [PDF]

open access: yesVirus Research, 2017
Reverse transcriptases (RTs) play a major role in the replication of Retroviridae, Metaviridae, Pseudoviridae, Hepadnaviridae and Caulimoviridae. RTs are enzymes that are able to synthesize DNA using RNA or DNA as templates (DNA polymerase activity), and degrade RNA when forming RNA/DNA hybrids (ribonuclease H activity).

Variation in False-Negative Rate of Reverse Transcriptase Polymerase Chain Reaction–Based SARS-CoV-2 Tests by Time Since Exposure

open access: yesAnnals of Internal Medicine, 2020
Background: Tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) based on reverse transcriptase polymerase chain reaction (RT-PCR) are being used to “rule out” infection among high-risk persons, such as exposed inpatients and health ...

Cost-effectiveness of the third-agent class in treatment-naive human immunodeficiency virus-infected patients in Portugal. [PDF]

open access: yesPLoS ONE, 2012
IntroductionCurrent Portuguese HIV treatment guidelines recommend initiating antiretroviral therapy with a regimen composed of two Nucleoside Reverse Transcriptase Inhibitors plus one Non-nucleoside Reverse Transcriptase Inhibitor (2NRTI+NNRTI) or two ...

Diagnostic Performance of CT and Reverse Transcriptase-Polymerase Chain Reaction for Coronavirus Disease 2019: A Meta-Analysis

open access: yesRadiology, 2020
Background Recent studies have suggested that chest computed tomography (CT) scans could be used as a primary screening or diagnostic tool for coronavirus disease 2019 (COVID-19) in epidemic areas.

Reverse Transcriptase-Polymerase Chain Reaction

open access: yesDefinitions, 2020
A laboratory procedure in which an RNA strand is first transcribed into a DNA complement and then subjected to PCR amplification. Transcribing an RNA strand into a DNA complement is termed reverse transcription and is done by the enzyme reverse ...

The mechano-chemistry of a monomeric reverse transcriptase [PDF]

open access: yesNucleic Acids Research, 2017
ABSTRACTRetroviral reverse transcriptase catalyses the synthesis of an integration-competent dsDNA molecule, using as a substrate the viral RNA. Using optical tweezers, we follow the Murine Leukemia Virus reverse transcriptase as it performs strand-displacement polymerization on a template under mechanical force.
