DGR mutagenic transposition occurs via hypermutagenic reverse transcription primed by nicked template RNA. [PDF]

, 2017
Diversity-generating retroelements (DGRs) are molecular evolution machines that facilitate microbial adaptation to environmental changes. Hypervariation occurs via a mutagenic retrotransposition process from a template repeat (TR) to a variable repeat ...

Protein expression from unintegrated HIV-1 DNA introduces bias in primary in vitro post-integration latency models [PDF]

, 2016
To understand the persistence of latently HIV-1 infected cells in virally suppressed infected patients, a number of in vitro models of HIV latency have been developed.

Small Dumbbell Oligonucleotides Inhibitors of RNase H Activity of MOMULV Reverse Transcriptase

E-Journal of Chemistry, 2011
The small dumbbell oligonucleotides containing loops of phosphodiester (OL-1), two trimethylene, C3 moieties in each loop (OL-2) and phosphorothioate (OL-3) linkages were synthesized.

The Molecular Docking of Specific Reverse Transcriptase Inhibitory Ligands onto the Molecular Model of HIV-1 Reverse Transcriptase [PDF]

Trends in Pharmaceutical Sciences
HIV-1 reverse transcriptase (RT) is a crucial enzyme in HIV replication and AIDS progression. It consists of p66 and p51 subunits and converts viral RNA into double-stranded DNA for integration into the host cell's genome.

CDK1 dependent phosphorylation of hTERT contributes to cancer progression

Nature Communications, 2020
Regulated telomerase reverse transcriptase (hTERT) activity is common in human tumors. Here, the authors show that hTERT is phosphorylated by CDK1 and that this event is necessary for hTERT-mediated RNA dependent RNA polymerase activity but not for ...

Drug-related mutational patterns in hepatitis B virus (HBV) reverse transcriptase proteins from Iranian treatment-Naïve chronic HBV patients [PDF]

, 2013
Background: Immunomodulators and Nucleotide analogues have been used globally for the dealing of chronic hepatitis B virus (HBV) infection. However, the development of drug resistance is a major limitation to their long-term effectiveness.

Reverse Transcriptase and Cellular Factors: Regulators of HIV-1 Reverse Transcription

Viruses, 2009
There is ample evidence that synthesis of HIV-1 proviral DNA from the viral RNA genome during reverse transcription requires host factors. However, only a few cellular proteins have been described in detail that affect reverse transcription and interact ...

Exploring the role of the α-carboxyphosphonate moiety in the HIV-RT activity of α-carboxy nucleoside phosphonates [PDF]

, 2016
As α-carboxy nucleoside phosphonates (α-CNPs) have demonstrated a novel mode of action of HIV-1 reverse transcriptase inhibition, structurally related derivatives were synthesized, namely the malonate 2, the unsaturated and saturated bisphosphonates 3 ...

Cis‐regulatory and long noncoding RNA alterations in breast cancer – current insights, biomarker utility, and the critical need for functional validation

Molecular Oncology, EarlyView.
The noncoding region of the genome plays a key role in regulating gene expression, and mutations within these regions are capable of altering it. Researchers have identified multiple functional noncoding mutations associated with increased cancer risk in the genome of breast cancer patients.

Higher Efficiency In Prediction Of TIBO Activity By Evolutionary Neural Network [PDF]

, 2011
The treatment of acquired immunodeficiency syndrome (AIDS) is a challenging medical problem. TIBO is a nonnucleoside reverse transcriptase inhibitor, which binds non-competitively to the hydrophobic pocket on the p66 subunit of RT enzyme.
