Nature Communications

Spatiotemporal organisation of residual disease in mouse and human BRCA1-deficient mammary tumours and breast cancer

D. Túrós et al., including A. Valdeolivas

Following tumour cells and their microenvironment through treatment, residual disease and recurrence.

Research note

A collaborative study combining single-cell RNA sequencing, spatial transcriptomics and imaging mass cytometry to investigate how treatment-tolerant cells persist in breast cancer.

ActiveVisium: Leveraging Active Learning to Enhance Manual Pathologist Annotation in 10x Visium Spatial Transcriptomics Experiments

J. Vasiljević, I. Berenguer Veiga, K. Hahn, P. Schwalie & A. Valdeolivas

Bringing pathologists into the learning loop to make spatial annotation more efficient.

Research note

Active learning uses tissue morphology and optional gene expression to select informative spots for expert annotation. The work evaluates this approach across breast cancer, colorectal cancer and kidney samples.

Chrysalis: decoding tissue compartments in spatial transcriptomics with archetypal analysis

D. Túrós, J. Vasiljevic, K. Hahn, S. Rottenberg & A. Valdeolivas

Finding spatially distinct cellular niches without an external single-cell reference.

Research note

Chrysalis combines spatially variable gene detection with archetypal analysis to identify tissue compartments and their gene expression signatures. Its Python implementation integrates with Scanpy-based workflows.

2024Applied AI

Nature Methods

Contextual AI models for single-cell protein biology

M. M. Li et al., including A. Valdeolivas

Learning protein representations that account for the cell types in which proteins act.

Research note

PINNACLE is a geometric deep learning approach to context-aware protein representations. It connects protein interaction networks with single-cell information to study protein function and therapeutic targets.

2024Spatial biology

npj Precision Oncology

Profiling the heterogeneity of colorectal cancer consensus molecular subtypes using spatial transcriptomics

A. Valdeolivas, B. Amberg, N. Giroud et al.

Resolving molecular subtypes in their tissue context, beyond a single bulk tumour label.

Research note

Spatial transcriptomics and single-cell RNA sequencing reveal how molecular programmes relate to tumour, stromal and non-neoplastic regions. Analysis scripts, notebooks and processed data accompany the study.

2019Network biology

Bioinformatics

Random walk with restart on multiplex and heterogeneous biological networks

A. Valdeolivas, L. Tichit, C. Navarro et al.

Exploring connected layers of biological knowledge to prioritise disease-associated genes.

Research note

An extension of random walk with restart to multiplex and heterogeneous networks, with an open-source R package for integrating different interaction types and gene–disease associations. The article appeared online in 2018 and in the 2019 journal issue.
