Certain sets of genes are derived from gene duplication and share substantial sequence similarity in , presenting a significant challenge in determining the specific roles of each gene and their collective impact on cellular processes. Here, we show that a collection of genes can be disrupted in a single animal via multiple rounds of CRISPR/Cas9 mediated genome editing. We found that up to three genes can be simultaneously disrupted in a single editing event with high efficiency. Our approach offers an opportunity to explore the genetic interaction and molecular underpinning of gene clusters with redundant function.

The crystallization behavior of ionic liquids (ILs) 1-butyl-3-methylimidazolium [BMIM] hexafluorophosphate [PF] and chloride [Cl] is investigated upon confinement in 2.3 or 8.2 nm diameter silica nanopore arrays, along with the effects of covalently modifying the pore walls with 1-(3-trimethoxysilylpropyl)3-methylimidazolium [TMS-MIM] groups.

Insulin resistance is a heritable risk factor for many chronic diseases; however, the genetic drivers remain elusive. In seeking these, we performed genetic mapping of insulin sensitivity in 670 chow-fed Diversity Outbred in Australia (DOz) mice and identified a genome-wide significant locus (QTL) on chromosome 8 encompassing 17 defensin genes. By taking a systems genetics approach, we identified alpha-defensin 26 (Defa26) as the causal gene in this region.

Traditional live attenuated vaccines (LAVs) are typically developed through serial passaging or genetic engineering to introduce specific mutations or deletions. While viral RNA secondary or tertiary structures have been well-documented for their multiple functions, including binding with specific host proteins, their potential for LAV design remains largely unexplored. Herein, using Zika virus (ZIKV) as a model, we demonstrate that targeted disruption of the primary sequence or tertiary structure of a specific viral RNA element responsible for Musashi-1 (MSI1) binding leads to a tissue-specific attenuation phenotype in multiple animal models.

Background: Prostate cancer (PRAD) is a common malignancy in men, and exposure to soil pollutants may contribute to its development. And exposure to soil pollutant has been linked to its development, as well as to other diseases including cardiovascular disorders, neurological conditions, and additional cancers.
Methods: This study integrates network toxicology, machine learning, and advanced technologies to investigate the mechanisms through which soil pollutants affect prostate cancer.

The cytosolic iron-sulfur cluster assembly (CIA) targeting complex maturates over 30 cytosolic and nuclear Fe-S proteins, raising the question of how a single complex recognizes such a diverse set of clients. The discovery of a C-terminal targeting complex recognition (TCR) peptide in up to 25% of CIA clients provided a clue to substrate specificity, yet the molecular and energetic basis for this interaction remained unresolved. By integrating computational and biochemical approaches, we show that the TCR peptide binds a conserved interface between the Cia1 and Cia2 subunits of the targeting complex, even in the absence of the Fe-S cluster.
