USP2 inhibition prevents infection with ACE2- dependent coronaviruses in vitro and is protective against SARS-CoV-2 in mice

Project description:In this study, we identified USP2 as a physiological deubiquitinase of ACE2 and USP2 inhibition led to ACE2 protein destruction, thereby preventing infections of coronaviruses that reliant on ACE2

In vivo inhibition of nuclear ACE2 translocation protects against SARS-CoV-2 replication and lung damage through epigenetic imprinting

Project description:In vitro, ACE2 translocates to the nucleus to induce SARS-CoV-2 replication. Here, using digital spatial profiling of lung tissues from SARS-CoV-2-infected golden Syrian hamsters, we show that a specific and selective peptide inhibitor of nuclear ACE2 (NACE2i) inhibits viral replication two days after SARS-CoV-2 infection. NACE2i also prevents inflammation and macrophage infiltration, and increases NK cell infiltration in bronchioles. NACE2i treatment restores host translation in infected hamster bronchiolar cells.

Regulation by the homologous Ace2 and Swi5 factors of Saccharomyces cerevisiae

Project description:The homologous Ace2 and Swi5 transcription factors of Saccharomyces cerevisiae have identical DNA-binding domains, and both are cell cycle regulated. There are common target genes, as well as genes activated only by Ace2 and other genes activated only by Swi5. Keywords: genetic modification RNA was isolated from four strains: wild type, ace2 gene deletion, swi5 gene deletion, and the ace2 swi5 double gene deletion. RNAs from the three mutant strains were compared to wild type RNA in a microarray hybridization experiment.

The sequence of human ACE2 is suboptimal for binding the S spike protein of SARS coronavirus 2

Project description:The rapid and escalating spread of SARS coronavirus 2 (SARS-CoV-2) poses an immediate public health emergency, and no approved therapeutics or vaccines are currently available. The viral spike protein S binds membrane-tethered ACE2 on host cells in the lungs to initiate molecular events that ultimately release the viral genome intracellularly. The extracellular protease domain of ACE2 inhibits cell entry of both SARS and SARS-2 coronaviruses by acting as a soluble decoy for receptor binding sites on S, and is a promising candidate for therapeutic and prophylactic development. Using deep mutagenesis, variants of ACE2 are identified with increased binding to the receptor binding domain of S at a cell surface. Mutations are found across the protein-protein interface and also at buried sites where they are predicted to enhance folding and presentation of the interaction epitope. The mutational landscape offers a preliminary blueprint for engineering high affinity ACE2 receptors to meet this unprecedented challenge.

Effects of ACE2 on BMPR2 mutation-mediated defects in gene expression

Project description:BMPR2 mutation causes pulmonary arterial hypertension (PAH); ACE2 treatment can resolve established BMPR2-mediated PAH. The purpose of this study was to uncover the molecular mechanism behind this. Four groups: +/- ACE2 and +/- BMPR2 transgene, two arrays each, each array a pool of three animals.

The Ndr/LATS kinase Cbk1 regulates a specific subset of Ace2 functions and suppresses the hyphae-to-yeast transition in Candida albicans

Project description:The Regulation of Ace2 and Morphogenesis (RAM) pathway is an important regulatory network in the human fungal pathogen Candida albicans. The RAM pathway’s two most well-studied components, the NDR/Lats kinase Cbk1 and its putative substrate, the transcription factor Ace2, have a wide range of phenotypes and functions. It is not clear, however, which of these functions are specifically due to the phosphorylation of Ace2 by Cbk1. To address this question, we first compared the transcriptional profiles of CBK1 and ACE2 deletion mutants. This analysis indicates that, of the large number of genes whose expression is affected by deletion of CBK1 and ACE2, only 5.5% of those genes are concordantly regulated. Our data also suggest that Ace2 directly or indirectly represses a large set of genes during hyphal morphogenesis. Second, we generated strains containing ACE2 alleles with alanine mutations at the Cbk1 phosphorylation sites. Phenotypic and transcriptional analysis of these ace2 mutants indicates that, as in Saccharomyces cerevisiae, Cbk1 regulation is important for daughter cell localization of Ace2 and cell separation during yeast phase growth. In contrast, Cbk1 phosphorylation of Ace2 plays a minor role in C. albicans yeast-to-hyphae transition. We have, however, discovered a new function for the Cbk1-Ace2 axis. Specifically, Cbk1 phosphorylation of Ace2 prevents the hyphae-to-yeast transition. To our knowledge, this is one of the first regulators of the C. albicans hyphae-to-yeast transition to be described. Finally, we present an integrated model for the role of Cbk1 in the regulation of hyphal morphogenesis in C. albicans.

Nonstructural protein 1 (nsp1) widespread RNA decay phenotype varies among Coronaviruses

Project description:Extensive remodeling of host gene expression by coronaviruses nsp1 proteins is a well-documented and conserved aspect of coronavirus-host takeover. Using comparative transcriptomics we investigate the diversity of transcriptional targets between nsp1 proteins between α- and β- coronaviruses. Additionally, Affinity Purification Mass-Spectrometry was implemented to identify common and divergent interactors between the nsp1 proteins. While we detected widespread RNA destabilization between the different nsp1s, closely related nsp1 showed little similarities in clustering of targeted genes. Partial overlapping transcriptional targeting between α-CoV 229E and MERS nsp1 may suggest a shared similar targeting mechanism, as MERS nsp1 preferentially targets nuclear transcripts. Our interactome data shows great variance between nsp1 interactions, with 229E nsp1, the smallest tested here, interacts with the most host proteins, while MERS nsp1 only engaged with a few. While nsp1 is a rather well-conserved protein with consistent functions across different coronaviruses, its precise effects on host cells is virus-specific.

Targeting Transcriptional Regulation of SARS-CoV-2 Entry Factors ACE2 and TMPRSS2

Project description:SARS-CoV-2, the virus responsible for COVID-19, employs two key host proteins to gain entry and replicate within cells, angiotensin-converting enzyme 2 (ACE2) and the cell surface transmembrane protease serine 2 (TMPRSS2). TMPRSS2 was first characterized as an androgen-regulated gene in the prostate. Supporting a role for sex hormones, males relative to females are disproportionately affected by COVID-19 in terms of mortality and morbidity. Several studies, including one employing a large epidemiological cohort, suggested that blocking androgen signaling is protective against COVID-19. Here, we demonstrate that androgens regulate the expression of ACE2, TMPRSS2, and androgen receptor (AR) in subsets of lung epithelial cells. AR levels are markedly elevated in males relative to females greater than 70 years of age. In males greater than 70 years old, smoking was associated with elevated levels of AR and ACE2 in lung epithelial cells. Transcriptional repression of the AR enhancesome with AR or bromodomain and extraterminal domain (BET) antagonists inhibited SARS-CoV-2 infection in vitro. Taken together, these studies support further investigation of transcriptional inhibition of critical host factors in the treatment or prevention of COVID-19. These mouse data are part of a larger investigation (data not provided here) targeting the transcriptional regulation of SARS-CoV-2 entry factors ACE2 and TMPRSS2.
