AI Article Synopsis

  • Caenorhabditis elegans serves as an important model for studying how different organs and cells react to external influences, due to its unique tissue structures.
  • The study introduces a new single-nucleus RNA sequencing (snRNA-seq) method that addresses challenges faced with single-cell RNA sequencing in this organism.
  • The paper provides a detailed protocol for isolating the nuclei of C. elegans, particularly focusing on analyzing gene expression changes following alcohol exposure, with additional information found in the referenced study by Truong et al. (2023).

Article Abstract

Caenorhabditis elegans is a valuable model to study organ, tissue, and cell-type responses to external cues. However, the nematode comprises multiple syncytial tissues with spatial coordinates corresponding to distinct nuclear transcriptomes. Here, we present a single-nucleus RNA sequencing (snRNA-seq) protocol that aims to overcome difficulties encountered with single-cell RNA sequencing in C. elegans. We describe steps for isolating C. elegans nuclei for downstream applications including snRNA-seq applied to the context of alcohol exposure. For complete details on the use and execution of this protocol, please refer to Truong et al. (2023)..

Single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) techniques hold great value in evaluating the heterogeneity and spatial characteristics of hematopoietic cells within tissues. These two techniques are highly complementary, with scRNA-seq offering single-cell resolution and ST retaining spatial information. However, there is an urgent demand for well-organized and user-friendly toolkits capable of handling single-cell and spatial information.

Protocol for identifying Dicer as dsRNA binding and cleaving reagent in response to transfected dsRNA.

Mammalian Dicer has been proved to be functional on double-stranded RNAs (dsRNAs) and involved in antiviral immunity or immune regulation. Here, we present a protocol for identifying Dicer as a dsRNA binding and cleaving factor to transfected dsRNA in cell lines, based on small RNA sequencing (RNA-seq) and dsRNA-immunoprecipitation (dsRNA-IP). We detail both experimental processes and analysis on small RNA-seq data.

Hair cells in the mammalian cochlea are highly vulnerable to damage from drug toxicity, noise exposure, aging, and genetic mutations, with no capacity for regeneration. Progress in hair cell protection research has been limited by the scarcity of cochlear tissue and suitable in vitro models. Here, we present a novel one-step, self-organizing inner ear organoid system optimized with small molecules, which bypasses the need for multi-step expansion and forced differentiation protocols.

The p60 subunit of the chromatin assembly factor-1 complex, that is, chromatin assembly factor-1 subunit B (CHAF1B), is a histone H3/H4 chaperone crucial for the transcriptional regulation of cell differentiation and self-renewal. CHAF1B is overexpressed in several cancers and may represent a potential target for cancer therapy. However, its expression and clinical significance in lung squamous-cell carcinoma (LUSC) remain unclear.

The construction of artificial reefs (ARs) is an effective way to restore habitats and increase and breed fishery resources in marine ranches. However, studies on the impacts of ARs on the structure, function, and assembly patterns of the bacterial community (BC), which is important in biogeochemical cycles, are lacking. The compositions, diversities, assembly patterns, predicted functions, and key environmental factors of the attached and free-living microbial communities in five-year ARs (O-ARs) and one-year ARs (N-ARs) in Fangchenggang, China, were analyzed via 16S rRNA gene sequencing.
