Structural and molecular characterization of paraventricular thalamic glucokinase‐expressing neuronal circuits in the mouse

open access: yesJournal of Comparative Neurology, Volume 530, Issue 11, Page 1773-1949, August 2022., 2022
By using a genetically modified mouse model and viral tracing approaches, we mapped both the anterograde and the retrograde projections of a subpopulation of neurons in the anterior paraventricular thalamic nucleus, molecularly defined by the expression of glucokinase (GckaPVT).

Bioluminometric Method for Real-Time Detection of Reverse Transcriptase Activity

open access: yesBioTechniques, 1998
A simple and sensitive technique for detection of reverse transcriptase (RT) activity in real time has been developed. The technique is based on continuous detection of the inorganic pyrophosphate formed in the RT-catalyzed reaction by a luminometric ...

High-Temperature, Nonradioactive Primer Extension Assay for Determination of a Transcription-Initiation Site

open access: yesBioTechniques, 1998
We have developed a simple and safe method for the determination of a transcription-initiation site. In this method, reverse transcriptase of the avian myeloblastosis virus or rTth DNA polymerase from Thermus thermopilus was used with a fluorescein ...

A single subunit from avian myeloblastosis virus with both RNA-directed DNA polymerase and ribonuclease H activity.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1973
Two structurally distinct forms of RNA-directed DNA polymerase from avian myeloblastosis virus were resolved by chromatography on phosphocellulose and purified. In addition to RNA-directed DNA polymerase activity, both enzymes had ribonuclease H (RNase H)

Rapid detection of wheat yellow mosaic virus by reverse transcription loop-mediated isothermal amplification

open access: yesVirology Journal, 2011
For the detection of wheat yellow mosaic virus (WYMV), we established a reverse transcription loop-mediated isothermal amplification (RT-LAMP) method.

The GAMYB gene in rye: sequence, polymorphisms, map location, allele-specific markers, and relationship with α-amylase activity

open access: yesBMC Genomics, 2020
Background Transcription factor (TF) GAMYB, belonging to MYB family (named after the gene of the avian myeloblastosis virus) is a master gibberellin (GA)-induced regulatory protein that is crucial for development and germination of cereal grain and ...

Evidence that the RNAseH activity of the duck hepatitis B virus is unable to act on exogenous substrates

open access: yesBMC Microbiology, 2001
Background The hepadnaviral reverse transcriptase can synthesize DNA on its native RNA template within viral cores but it is usually unable to synthesize DNA employing exogenous nucleic acids as a template.

Mechanism of action of ribonuclease H isolated from avian myeloblastosis virus and Escherichia coli.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1973
Purified preparations of RNA-dependent DNA polymerase isolated from avain myeloblastosis virus contain RNase H activity. Labeled ribohomopolymers are degraded in the presence of their complementary deoxyribopolymer, except [(3)H]poly(U).poly(dA).

Reverse Transcriptase Adds Nontemplated Nucleotides to cDNAs During 5′-RACE and Primer Extension

open access: yesBioTechniques, 2001
In determining the terminal sequences of the genomic dsRNAs of rotavirus by 5′-rapid amplification of cDNA ends (5′-RACE), it was found that most of the viral cDNAs contained extra nucleotides at their 5′ termini that had not been reported before on any ...

Avian myeloblastosis virus proteins in leukemic chicken myeloblasts [PDF]

open access: yesJournal of Virology, 1980
We have analyzed the avian myeloblastosis virus proteins in two types of leukemic myeloblasts: established myeloblastic cell lines (DU 1765 and DU 11157) and leukemic myeloblasts obtained from the peripheral blood of a leukemic C/E Spafas chicken (no. 21957). Using monospecific antisera for immunoprecipitation and polyacrylamide gel electrophoresis, we
