The explosion of bioinformatics technologies in the form next generation sequencing (NGS) has facilitated a massive influx genomics data short reads. Short read mapping is therefore fundamental component pipelines which routinely match these reads against reference genomes for contig assembly. However, such techniques have seldom been applied to microbial marker gene studies, mostly relied on novel heuristic approaches. We propose NINJA Is Not Just Another OTU-Picking Solution (NINJA-OPS, or...
Progression through the G1 phase of cell cycle is most highly regulated step in cellular division. We employed a chemogenetic approach to discover novel networks that regulate progression. This uncovered functional clusters genes altered sensitivity cells inhibitors G1/S transition. Mutation components Polycomb Repressor Complex 2 rescued proliferation inhibition caused by CDK4/6 inhibitor palbociclib, but not S or mitosis. In addition its core catalytic subunits, mutation PRC2.1 accessory...
SARS-CoV-2 depends on host cell components for infection and replication. Identification of virus-host dependencies offers an effective way to elucidate mechanisms involved in viral If druggable, factor may present attractive strategy anti-viral therapy. In this study, we performed genome wide CRISPR knockout screens Vero E6 cells four human lines including Calu-3, UM-UC-4, HEK-293 HuH-7 identify genetic regulators infection. Our findings identified only ACE2, the cognate entry receptor, as...
Fungal pathogens such as Candida albicans pose a significant threat to human health with limited treatment options available. One strategy expand the therapeutic target space is identify genes important for pathogen growth in host-relevant environments. Here, we leverage pooled functional genomic screening fitness of C. diverse conditions. We an essential gene no known Saccharomyces cerevisiae homolog, C1_09670C, and demonstrate that it encodes subunit 3 replication factor A (Rfa3)....
DNA replication requires precise regulation achieved through post-translational modifications, including ubiquitination and SUMOylation. These modifications are linked by the SUMO-targeted E3 ubiquitin ligases (STUbLs). Ring finger protein 4 (RNF4), one of only two mammalian STUbLs, participates in double-strand break repair resolving DNA–protein cross-links. However, its role has been poorly understood. Using CRISPR/Cas9 genetic screens, we discovered an unexpected dependency RNF4 mutants...

CRISPR-Cas9 screens facilitate the discovery of gene functional relationships and phenotype-specific dependencies. The Cancer Dependency Map (DepMap) is largest compendium whole-genome CRISPR aimed at identifying cancer-specific genetic dependencies across human cell lines. A mitochondria-associated bias has been previously reported to mask signals for genes involved in other functions, thus, methods normalizing this dominant signal improve co-essentiality networks are interest. In study, we...
Drafting in Magic the Gathering is a sub-game within larger trading card game, where several players progressively build decks by picking cards from common pool. poses an interesting problem for game and AI research due to its large search space, mechanical complexity, multi-player nature, hidden information. Despite this, drafting remains understudied, part lack of high-quality, public datasets. To rectify this problem, we present dataset over 100,000 simulated, anonymized human drafts...
A large fraction of human and mouse autosomal genes are subject to random monoallelic expression (MAE), an epigenetic mechanism characterized by allele-specific gene that varies between clonal cell lineages. MAE is highly cell-type specific mapping it in a number tissue types can provide insight into its biological function. Its detection, however, remains challenging. We previously reported sequence-independent chromatin signature identifies, with high sensitivity specificity, multiple...
Current approaches to define chemical-genetic interactions (CGIs) in human cell lines are resource-intensive. We designed a scalable screening platform by generating DNA damage response (DDR)-focused custom sgRNA library targeting 1011 genes with 3033 sgRNAs. performed five proof-of-principle compound screens and found that the compounds' known modes-of-action (MoA) were enriched among CGIs. These recapitulated expected CGIs at comparable signal-to-noise ratio (SNR) relative genome-wide...

ABSTRACT CRISPR screens are used extensively to systematically interrogate the phenotype-to-genotype problem. In contrast early screens, which defined core cell fitness genes, most current efforts now aim identify context-specific phenotypes that differentiate a line, genetic background or condition of interest, such as drug treatment. While CRISPR-related technologies have shown great promise and fast pace innovation, better understanding standards methods for quality assessment screen...
