PULPO v1.0 is a novel, fully automated pipeline designed for the preprocess and extraction of mutational signatures from raw Optical Genome Mapping (OGM) data. Built using Snakemake and executed within an isolated, Conda-managed environment, PULPO transforms complex cytogenetic alterations, captured at ultra-high resolution, into Catalogue of somatic mutations in Cancer (COSMIC)-based mutational signatures. This innovative approach not only enables researchers to work directly from raw OGM inputs but also streamlines the traditionally complex process of signature extraction, making advanced oncogenomic analyses accessible to users with varying levels of bioinformatics expertise. By facilitating the integration of comprehensive structural variants (SVs) and copy number variants (CNVs) data with established signature catalogs, PULPO paves the way for improved diagnostic accuracy and personalized therapeutic strategies.

DiffMethylTools: a toolbox of the detection, annotation and visualization of differential DNA methylation
DNA methylation is a compulsory and fundamental epigenetic mechanism, and its significant changes (i.e., differential methylation) regulate gene expression, cell-type specification and disease progression without altering the underlying DNA sequence. Differential methylation biomarkers were widely used as inputs for various downstream investigations, and differential methylation could be detected ...

Regulation Flow Analysis discovers molecular mechanisms of action from large knowledge databases
Drug development is a long and expensive process, with only a small fraction of potential drugs being finally approved. The challenge of drug development is rooted in our limited understanding of biological systems and the disease processes that drugs are trying to modulate. We propose a novel method, called Regulation Flow Analysis (RFA), which is based on the principles of biological regulation,...

Modelling punctuated similarity
Inter-subject, pairwise similarity models provide a methodological resource for flexibly measuring complex, non-linear relationships between brain and behavior. Similarity models, however, can extend beyond brain behavior relationships and can be readily applied to any data where they may be useful. The work presented in this paper introduces a new way of modelling similarity, termed punctuated si...

Mechanistic modeling and machine learning identifies optimum radiotherapy schedules to prevent treatment-induced metastasis
Lung cancer patients often experience increased metastasis formation after radiotherapy. However, it is incompletely understood whether radiation affects the migratory behavior of tumor cells and how altered radiotherapy schedules might mitigate this risk. To address these questions, we performed live-cell microscopy experiments to profile changes in cell migration during radiation across 12 cance...

A moderated statistical test for detecting shifts in homeolog expression ratios in allopolyploids
Allopolyploids arise through hybridization between related species, carrying multiple sets of chromosomes from distinct progenitor, referred to as subgenomes. Within allopolyploids, duplicated genes across subgenomes, called homeologs, are thought to enhance environmental robustness by shifting their expression ratios depending on environmental and developmental changes. However, existing methods ...

In Situ Inference of Copy Number Variations in Image-Based Spatial Transcriptomics
Copy number variations (CNVs) drive cancer progression. So far, spatial CNV inference has relied on whole transcriptome-based sequencing technologies. However, advances in image-based spatial transcriptomics (iST) now enable high-plex gene measurement in situ. Here, we introduce an approach that adapts CNV inference to iST data, enabling spatial mapping of malignant clones and the tumor microenvir...

OMIDIENT: Multiomics Integration for Cancer by Dirichlet Auto-Encoder Networks
To achieve a more comprehensive understanding of cancer, novel computational methods are required for the integrative analysis of data from different molecular layers, such as genomics, transcriptomics, and epigenomics. Here, we present a novel multi-omics integrative method that performs unsupervised representation learning, referred to as OMIDIENT: multiOMics Integration for cancer by DIrichlet ...

Fold-Conditioned De Novo Binder Design via AlphaFold2-Multimer Hallucination.
De novo protein binder design has been revolutionized by deep learning methods, yet controlling binder topology remains a challenge. We introduce a fold-conditioned AlphaFold2-Multimer hallucination framework - FoldCraft - guided by a contact map similarity loss, enabling precise generation of binders with user-defined structural folds. This single loss function enforces fold-specific geometry whi...
