Studies have shown that IFI16 acts as an antiviral restriction factor against a number of DNA viruses, by inhibiting viral replication or transcription through epigenetic modifications. However, till date, no specific epigenetic function of IFI16 has been identified. Here, we have discovered that IFI16 recruits two histone methyltransferases on the KSHV episome leading to altered Histone H3K9 methylation, thus regulating its lifecycle.

Establishment and succession of the human microbiome begins at birth and microbial composition adapts alongside human development and growth. Development of a healthy signature microbial community has significant effects on health.This study followed 18 very low birth weight (VLBW) infants, measured initially in the from Neonatal Intensive Care Unit (NICU), at the age of two to three years old.

RNA interference (RNAi) using small interfering RNAs (siRNAs) is an important technology for down-regulation of gene expression and a powerful tool to study cellular processes and pathways. Previously, large collections of siRNAs were available only for traditional experimental model systems, such as human and mouse, and predominantly provided as chemically synthesized libraries.

We utilized paired synthetic crRNAs coupled with our synthetic tracrRNA in cells transduced with lentiviral Cas9 to perform a functional knockout on hsa-miR-221. This three-part system (crRNA, tracrRNA and Cas9) has demonstrated efficient gene editing when used with only one guide RNA, but the goal was to use two crRNAs to remove the entire stem-loop.

Gene knockout using CRISPR-Cas9 has dramatically transformed biological research and has been rapidly applied to loss-of-function screening primarily using pooled lentiviral sgRNA libraries. A synthetic CRISPR RNA (crRNA) approach is amenable to screening in arrayed, well-by-well fashion and expands the types of phenotypic readouts that can be used, including high-content and morphology-based assays.

Previous studies suggested that Mycobacterium tuberculosis obtains nitrogen from a diverse range of intracellular nutrients including amino acids. Here, we use a novel system’s based three-pronged approach to define pathways for uptake and assimilation of nitrogen.

This study investigates the role of histone deacetylase 6 (HDAC6) in chronic lymphocytic leukemia and establishes it as a novel therapeutic target for the treatment of this disease.

In summary, ISG15 expression levels are crucial for trophoblast morphology and function (migration/invasion). By blocking trophoblast invasion, reduced ISG15 levels could contribute to impaired spiral artery transformation that reduces utero-placental blood flow in preeclampsia. Thus, agents inducing ISG15 expression are likely to be therapeutic in preeclampsia.

We describe the natural history of a cohort of 12 patients with confirmed partial RAG1/2 mutations and autoimmunity at a young age. We were seeking the link between viral infections and autoimmunity and tested candidate biomarkers that may reflect the underlying RAG1/2 protein deficiency.
