Molecular insights into type I interferon suppression and enhanced pathogenicity by species B human adenoviruses B7 and B14.

Human adenoviruses (HAdVs) are small DNA viruses that generally cause mild disease. Certain strains, particularly those belonging to species B HAdVs, can cause severe pneumonia and have a relatively high mortality rate. Little is known about the molecular aspects of how these highly pathogenic species affect the infected cell and how they suppress innate immunity.

ARGLU1 enhances promoter-proximal pausing of RNA polymerase II and stimulates DNA damage repair.

Arginine and glutamate rich 1 (ARGLU1) is a poorly understood cellular protein with functions in RNA splicing and transcription. Computational prediction suggests that ARGLU1 contains intrinsically disordered regions and lacks any known structural or functional domains. We used adenovirus Early protein 1A (E1A) to probe for critical regulators of important cellular pathways and identified ARGLU1 as a significant player in transcription and the DNA damage response pathway.

A predominant role of genotypic variation in both expression of sperm competition genes and paternity success in .

Sperm competition is a crucial aspect of male reproductive success in many species, including and seminal fluid proteins (Sfps) can influence sperm competitiveness. However, the combined effect of environmental and genotypic variation on sperm competition gene expression remains poorly understood. Here, we used Genetic Reference Panel (DGRP) inbred lines and manipulated developmental population density (i.

In Mitosis You Are Not: The NIMA Family of Kinases in , Yeast, and Mammals.

The Never in mitosis gene A (NIMA) family of serine/threonine kinases is a diverse group of protein kinases implicated in a wide variety of cellular processes, including cilia regulation, microtubule dynamics, mitotic processes, cell growth, and DNA damage response. The founding member of this family was initially identified in and was found to play important roles in mitosis and cell division. The yeast family has one member each, Fin1p in fission yeast and Kin3p in budding yeast, also with functions in mitotic processes, but, overall, these are poorly studied kinases.

Adenovirus 5 Vectors Expressing SARS-CoV-2 Proteins.

SARS-CoV-2 coronavirus is a recently identified novel coronavirus that is the causative agent of the COVID-19 pandemic that began in 2020. An intense research effort has been undertaken by the research community in order to better understand the molecular etiology of this virus and its mechanisms of host cell subjugation and immune system evasion. To facilitate further research into the SARS-CoV-2 coronavirus we have generated adenovirus 5-based viral vectors that express SARS-CoV-2 proteins-S, N, E, NSP7, NSP8, and NSP12 as hemagglutinin (HA)-tagged and untagged variants.
