AI Article Synopsis

  • CRISPR/Cas9 gene knockout libraries offer a powerful approach for conducting functional screens by providing specific sgRNA sequences optimized for effectiveness and minimal off-target effects.
  • These sgRNAs specifically target important regions of genes, including 5' exons and conserved protein domains, to enhance the likelihood of successfully inactivating target genes.
  • The described method allows labs to easily create custom CRISPR libraries of different sizes and coverage from a single oligo pool, making it resource-efficient for functional genomics research.

Article Abstract

CRISPR/Cas9-based gene knockout libraries have emerged as a powerful tool for functional screens. We present here a set of pre-designed human and mouse sgRNA sequences that are optimized for both high on-target potency and low off-target effect. To maximize the chance of target gene inactivation, sgRNAs were curated to target both 5΄ constitutive exons and exons that encode conserved protein domains. We describe here a robust and cost-effective method to construct multiple small sized CRISPR library from a single oligo pool generated by array synthesis using parallel oligonucleotide retrieval. Together, these resources provide a convenient means for individual labs to generate customized CRISPR libraries of variable size and coverage depth for functional genomics application.

Nucleus-translocated GCLM promotes chemoresistance in colorectal cancer through a moonlighting function.

Nat Commun

January 2025

Department of Medical Oncology, State Key Laboratory of Oncology in South China, Guangdong Provincial Clinical Research Center for Cancer, Sun Yat-sen University Cancer Center, Guangzhou, PR China.

Metabolic enzymes perform moonlighting functions during tumor progression, including the modulation of chemoresistance. However, the underlying mechanisms of these functions remain elusive. Here, utilizing a metabolic clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 knockout library screen, we observe that the loss of glutamate-cysteine ligase modifier subunit (GCLM), a rate-limiting enzyme in glutathione biosynthesis, noticeably increases the sensitivity of colorectal cancer (CRC) cells to platinum-based chemotherapy.

The CRISPR-activated repair lineage tracing (CARLIN) mouse line uses DNA barcoding to enable high-resolution tracing of cell lineages in vivo (Bowling et al, Cell 181, 1410-1422.e27, 2020). CARLIN mice contain expressed barcodes that allow simultaneous interrogation of lineage and gene expression information from single cells.

Article Synopsis
  • Tumor resistance to immune checkpoint inhibitors may be connected to cellular senescence, particularly in fibroblasts, as shown by single-cell RNA sequencing analyses.
  • A fibroblast senescence-associated transcriptomic signature (FSS) links cellular senescence to tumor progression and immune dysfunction, demonstrating high predictive accuracy for ICI responses using machine learning.
  • CDC6 is identified as a key marker influencing ICI response by inducing fibroblast senescence and altering the tumor microenvironment, highlighting the potential for targeting fibroblast senescence in cancer therapy.

ALCAM is an entry factor for severe community acquired Pneumonia-associated Human adenovirus species B.

Nat Commun

December 2024

Department of Pulmonary and Critical Care Medicine, Ruijin Hospital, Institutes of Respiratory Diseases, School of Medicine, Shanghai Jiao Tong University and Shanghai Key Laboratory of Emergency Prevention, Diagnosis and Treatment of Respiratory Infectious Diseases, Shanghai, China.

Human adenovirus (HAdV) is a widely spread respiratory pathogen that can cause infections in multiple tissues and organs. Previous studies have established an association between HAdV species B (HAdV-B) infection and severe community-acquired pneumonia (SCAP). However, the connection between SCAP-associated HAdV-B infection and host factor expression profile in patients has not been systematically investigated.
