A reverse transcriptase ribozyme
A highly evolved RNA polymerase ribozyme was found to also be capable of functioning as a reverse transcriptase, an activity that has never been demonstrated before for RNA. This activity is thought to have been crucial for the transition from RNA to DNA

Computational development of rubromycin-based lead compounds for HIV-1 reverse transcriptase inhibition [PDF]
The binding of several rubromycin-based ligands to HIV1-reverse transcriptase was analyzed using molecular docking and molecular dynamics simulations. MM-PBSA analysis and examination of the trajectories allowed the identification of several promising ...

LINE-1 retrotransposon activation drives age-associated inflammation via cytoplasmic cDNA-STING/type I interferon signalling: therapeutic potential of reverse transcriptase inhibition [PDF]
Retrotransposable elements are harmful at several levels, and host surveillance systems fail to consider all these elements in severe effects. The key role of retrotransposon in aging and age-associated diseases remains unclear. We summarise whether LINE-

Viral reverse transcriptases [PDF]
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).

Retroviral restriction factor APOBEC3G delays the initiation of DNA synthesis by HIV-1 reverse transcriptase. [PDF]
It is well established that the cytosine deaminase APOBEC3G can restrict HIV-1 virions in the absence of the virion infectivity factor (Vif) by inducing genome mutagenesis through deamination of cytosine to uracil in single-stranded HIV-1 (-)DNA. However,

Telomerase reverse transcriptase promotes angiogenesis in neonatal rats after hypoxic-ischemic brain damage [PDF]
Background Angiogenesis is an endogenous repair mechanism following hypoxic-ischemic brain damage (HIBD). Interestingly, recent studies have shown that angiogenesis can be regulated by telomerase reverse transcriptase (TERT), a critical component of ...

Reverse transcriptase inhibition: a way to defeat HIV
Human immunodeficiency virus (HIV) induces disease in humans that is known as AIDS (acquired immunodeficiency syndrome). First AIDS cases were registered in 1981, and later, types of HIV infection, such as HIV-1 and HIV-2 were identified.

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