Project description:Next generation sequencing (RAN-seq) was used to study the global effects of co-treatment of endothelial cells with U1 and LL-37. This lead to identification of differentially regulated genes and enriched pathways
Project description:Metagenome data from soil samples were collected at 0 to 10cm deep from 2 avocado orchards in Channybearup, Western Australia, in 2024. Amplicon sequence variant (ASV) tables were constructed based on the DADA2 pipeline with default parameters.
Project description:To better prepare for future viral outbreaks, scalable and adaptable platforms to study emerging infections are essential. Understanding virus–host interactions, particularly the mechanisms of cell entry, is critical for developing effective therapeutics and vaccines. Current approaches often rely on live virus assays requiring high-containment facilities, limiting speed, scalability, and accessibility. As a proof-of-principle, we developed a novel screening platform—Ceudovitox—using pseudotyped viruses (PVs) bearing the chikungunya virus (CHIKV) envelope protein. These PVs were engineered to express herpes simplex virus-1 thymidine kinase, enabling selective killing of infected cells with ganciclovir. A heterogeneous CRISPR-Cas9 knockout cell pool was then screened using this "killer" PV system, allowing identification of CHIKV entry factors via next-generation sequencing.
Project description:To survey avian leukosis virus subgroup J (ALV-J) integration in myeloid leukosis (ML) of chicken, we developed an ALV-J insertional identification platform based on hybrid-capture target enrichment and next-generation sequencing (NGS). In addition, we used gene expression profiling and bioinformatics to associate integration sites to transcriptional activity and to genetic features of the tumor cell genome. We selected six cases of ALV-J positive and diagnosed as ML for integration sites identify from commercial broiler breeder flocks in Guangdong Province of China between November 2011 and March 2012. All tumors were diagnosed on the basis of characteristic gross and microscopic lesions. Furthermore, PCR tests on the genomic DNA of tissues and virus isolation assay only showed ALV-J-specific positive results in previously study. We randomly chose 4 independent liver samples from the six cases for gene expression profile analysis. And 3 ALV-negative tissue samples from specific-pathogen-free (SPF) chickens at the same age were use as negative controls. Thus a total of 7 samples were hybridized, three representing control.
