Store-operated Ca2+ entry controls clonal expansion of T cells through metabolic reprogramming

open access: yesImmunity, 2017
&NA; Store‐operated Ca2+ entry (SOCE) is the main Ca2+ influx pathway in lymphocytes and is essential for T cell function and adaptive immunity. SOCE is mediated by Ca2+ release‐activated Ca2+ (CRAC) channels that are activated by stromal interaction ...

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

open access: yesMolecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

Cancer risk assessment of premalignant breast tissues from patients with BRCA mutations by genome profiling

open access: yesnpj Breast Cancer
Patients with germline pathogenic variants of BRCA1/2 genes have a particular predisposition to develop breast cancer. No clinical test has been developed to accurately and quantitatively evaluate their risk of developing breast cancer.

Spatiotemporal dynamics of clonal selection and diversification in normal endometrial epithelium

open access: yesNature Communications, 2022
Through regeneration, the endometrium accumulates somatic mutations that can lead to diseases like endometriosis and cancer. Here, the authors use genomics to analyse normal endometrial glands from different patient cohorts, detect rhizome structures ...

Replication stress triggers microsatellite destabilization and hypermutation leading to clonal expansion in vitro

open access: yesNature Communications, 2019
Mismatch repair (MMR)-deficient cancers are characterized by microsatellite instability (MSI) and hypermutation. However, it remains unclear how MSI and hypermutation arise and contribute to cancer development.

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

open access: yesMolecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

A pan-immunotherapy signature to predict intratumoral CD8+ T cell expansions

open access: yesNature Communications
Effective cancer immunotherapy relies on the clonal proliferation and expansion of CD8+ T cells in the tumor. However, our insights into clonal expansions are limited, owing to an inability to track the same clones in tumors over time. Here, we develop a

Stem cell graft dose and composition could impact on the expansion of donor-derived clones after allogeneic hematopoietic stem cell transplantation – a virtual clinical trial

open access: yesFrontiers in Immunology
IntroductionHematopoietic stem cell transplantation is a potentially curative intervention for a broad range of diseases. However, there is evidence that malignant or pre-malignant clones contained in the transplant can expand in the recipient and ...

A cancer rainbow mouse for visualizing the functional genomics of oncogenic clonal expansion

open access: yesNature Communications, 2019
Field cancerization is a premalignant process marked by clones of oncogenic mutations spreading through the epithelium. The timescales of intestinal field cancerization can be variable and the mechanisms driving the rapid spread of oncogenic clones are ...
