A ggplot-based single-gene viewer reveals insights into the translatome and other nucleotide-resolution omics data

Wu, H.-Y. L.Open in Google Scholar•Kaufman, I. D.Open in Google Scholar•Hsu, P. Y.Open in Google Scholar

Seeing is believing. Visualizing Ribo-seq and other sequencing data within genes of interest is a powerful approach to studying gene expression, but its application is limited by a lack of robust tools. Here, we introduce ggRibo, a user-friendly R package for visualizing individual gene expression, integrating Ribo-seq, RNA-seq, and other genome-wide datasets with flexible scaling options. ggRibo visualizes 3-nucleotide periodicity, a hallmark of translating ribosomes, within a gene-structure context, including introns and untranslated regions, enabling the study of novel ORFs, translation of different isoforms, and mechanisms of translational regulation. ggRibo can plot multiple Ribo-seq/RNA-seq datasets from different conditions for comparison. It also contains functions for plotting single-transcript view, reading-frame decomposition, and RNA-seq coverage alone. Importantly, ggRibo supports the visualization of other omics datasets that could also be presented with single-nucleotide resolution, such as RNA degradome, transcription start sites, translation initiation sites, and epitranscriptomic modifications. We demonstrate its utility with examples of upstream ORFs, downstream ORFs, nested ORFs, and differential isoform translation in humans, Arabidopsis, tomato, and rice. We also provide examples of multi-omic comparisons that reveal insights that connect the transcriptome, translatome, and degradome. In summary, ggRibo is an advanced single-gene viewer that offers a valuable resource for studying gene expression regulation through its intuitive and flexible platform.

SCNT: An R Package for Data Analysis and Visualization of Single-Cell and Spatial Transcriptomics
Background: The emergence of single-cell (SC) and spatial transcriptomics (ST) has revolutionized our understanding of gene expression dynamics in complex tissues. However, it also presents challenges for data analysis and visualization, particularly due to the complexity of ST data and the diversity of analysis platforms. The SCNT (Single-Cell, Single-Nucleus, and Spatial Transcriptomics Analysis...

Amira: detection of AMR genes directly from long reads using gene-space de Bruijn graphs
Accurate detection of antimicrobial resistance (AMR) genes is essential for the surveillance, epidemiology and genotypic prediction of AMR. This is typically done by generating an assembly from the sequencing reads of a bacterial isolate and running AMR gene detection tools on the assembly. However, despite advances in long-read sequencing that have greatly improved the quality and completeness of...

Limitations of Current Machine-Learning Models in Predicting Enzymatic Functions for Uncharacterized Proteins
Thirty to seventy percent of proteins in any given genome have no assigned function and have been labeled as the protein unknome. This large knowledge shortfall is one of the final frontiers of biology. Machine-Learning (ML) approaches are enticing, with early successes demonstrating the ability to propagate functional knowledge from experimentally characterized proteins. An open question is the a...

An improved model for prediction of de novo designed proteins with diverse geometries
Nature uses structural variations on protein folds to fine-tune the geometries of proteins for diverse functions, yet deep learning-based de novo protein design methods generate highly regular, idealized protein fold geometries that fail to capture natural diversity. Here, using physics-based design methods, we generated and experimentally validated a dataset of 5,996 stable, de novo designed prot...

sCIN: A Contrastive Learning Framework for Single-Cell Multi-omics Data Integration
The rapid advancement of single-cell omics technologies such as scRNA-seq and scATAC-seq has transformed our understanding of cellular heterogeneity and regulatory mechanisms. However, integrating these data types remains challenging due to distributional discrepancies and distinct feature spaces. To address this, we present a novel single-cell Contrastive INtegration framework (sCIN), that integr...

Machine learning driven acceleration of biopharmaceutical formulation development using Excipient Prediction Software (ExPreSo)
Formulation development of protein biopharmaceuticals has become increasingly challenging due to new modalities and higher desired drug substance concentrations. The constraint in drug substance supply and the need for many analytical methods means that only a small selection of excipients can be thoroughly tested in the lab. There are few in-silico tools developed to refine the candidate excipien...
