Sadanandam Lab
Our lab at the Botton-Champalimaud Pancreatic Cancer Centre is dedicated to uncovering the molecular and cellular mechanisms that drive gastrointestinal cancers, with a particular focus on pancreatic adenocarcinoma and neuroendocrine tumours (PanNETs). Using integrative systems biology, we aim to define how tumors interact with their surrounding microenvironment and tissues to influence disease progression, immune evasion, and therapeutic resistance.
A major focus of our research is the development of a comprehensive molecular atlas of pancreatic cancer cachexia, combining spatial and single-cell transcriptomics, metabolomics, and computational modeling to reveal tissue-specific and systemic drivers of cachexia. In parallel, we are investigating immune-metabolic tumour-host crosstalk, exploring how nutrient availability, immune cell states, and metabolic dynamics shape tumor behavior and response to therapy.
We also study biomarker and therapeutic target discovery across gastrointestinal cancers, including pancreatic, colorectal, and gastric cancers. By profiling tumor subtypes and their microenvironments, we aim to guide decisions about upfront surgery, neoadjuvant chemotherapy, or immunotherapy, with particular emphasis on identifying immunotherapy-responsive subgroups through genomic and molecular analysis.
Additionally, we apply machine learning to clinical, molecular, and metabolic datasets to uncover predictive patterns, stratify risk, and support the design of precision clinical trials. Our research bridges basic discovery with translational application, advancing personalized therapeutic strategies for patients with both pancreatic adenocarcinoma and PanNETs, along with other gastrointestinal cancers.
