Integrase-associated niche differentiation of endogenous large DNA viruses in crustaceans

Microbiology Spectrum
Crustacean genomes harbor sequences originating from nimaviruses, a family of large double-stranded DNA viruses infecting crustaceans. In this study, we recovered metagenome-assembled genomes of 27 endogenous nimaviruses from crustacean genome data ...

Bee products as alternatives in the treatment of viral infections

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Medicines used in the treatment of viral infections usually reduce symptoms. There is a need to develop drugs that inhibit the viruses and do not merely relieve the symptoms. Natural bee products possess many pharmacological properties and are widely used in folk medicine. There are many studies on the antibacterial effects of bee products but

Reconstructing an ancestral genotype of two hexachlorocyclohexane-degrading Sphingobium species using metagenomic sequence data. [PDF]

, 2014
Over the last 60 years, the use of hexachlorocyclohexane (HCH) as a pesticide has resulted in the production of >4 million tons of HCH waste, which has been dumped in open sinks across the globe.

A Bayesian approach to inferring chemical signal timing and amplitude in a temporal logic gate using the cell population distributional response [PDF]

, 2016
Stochastic gene expression poses an important challenge for engineering robust behaviors in a heterogeneous cell population. Cells address this challenge by operating on distributions of cellular responses generated by noisy processes.

A Mathematical Model for Allergic Reactions Induced by the Therapy of HIV

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT A new mathematical model for cell evolution in HIV is introduced and studied. Delay differential equations are used to capture the dynamics of immune system cells involved in allergies, as well as the evolution of HIV viruses, infected and uninfected CD4+$$ {}^{+} $$ cells, and cytotoxic T‐lymphocytes, under specific antiretroviral therapy ...

The Role of TNPO3 in HIV-1 Replication [PDF]

, 2012
TNPO3, transportin-SR2 or Tnp3, a member of the karyopherin β superfamily of proteins, is important for the ability of human immunodeficiency virus (HIV-1) to achieve productive infection, as TNPO3 depletion in human cells leads to a dramatic reduction ...

The Molecular Biology of HIV Integrase [PDF]

Future Virology, 2012
Integration of viral DNA into cellular DNA is an essential step in the replication cycle of HIV and other retroviruses. The first antiviral drugs that target integrase, the viral enzyme that catalyzes DNA integration, have recently been approved and more are in the pipeline. These drugs bind to an intermediate in DNA integration called the intasome, in

Target DNA bending by the Mu transpososome promotes careful transposition and prevents its reversal

eLife, 2017
The transposition of bacteriophage Mu serves as a model system for understanding DDE transposases and integrases. All available structures of these enzymes at the end of the transposition reaction, including Mu, exhibit significant bends in the ...
