Imaging and Molecular Annotation of Xenographs and Tumours (IMAXT): High throughput data and analysis infrastructure.

With the aim of producing a 3D representation of tumors, imaging and molecular annotation of xenografts and tumors (IMAXT) uses a large variety of modalities in order to acquire tumor samples and produce a map of every cell in the tumor and its host environment. With the large volume and variety of data produced in the project, we developed automatic data workflows and analysis pipelines. We introduce a research methodology where scientists connect to a cloud environment to perform analysis close to where data are located, instead of bringing data to their local computers.

FOXC2 promotes vasculogenic mimicry and resistance to anti-angiogenic therapy.

Vasculogenic mimicry (VM) describes the formation of pseudo blood vessels constructed of tumor cells that have acquired endothelial-like properties. VM channels endow the tumor with a tumor-derived vascular system that directly connects to host blood vessels, and their presence is generally associated with poor patient prognosis. Here we show that the transcription factor, Foxc2, promotes VM in diverse solid tumor types by driving ectopic expression of endothelial genes in tumor cells, a process that is stimulated by hypoxia.

The Joint Initiative for Teaching and Learning on Global Health Challenges and One Health experience on implementing an online collaborative course.

The "Joint Initiative for Teaching and Learning on Global Health Challenges and One Health" piloted the online course "Global Health Challenges and One Health in 2021. The present work documents this experience, lessons learned, and the future outlook of the course. A descriptive study was conducted based on the evaluations performed with the enrolled students and course coordinators.

Creating a platform to enable collaborative learning in One Health: The Joint Initiative for Teaching and Learning on Global Health Challenges and One Health experience.

The "Joint Initiative for Teaching and Learning on Global Health Challenges and One Health" targets education and training in Global Health Challenges and One Health, focusing on surpassing issues that affect One Health training programs. The present work describes the planning, implementation, and challenges to develop an international educational initiative among six partner institutions from four different countries, to build a collaborative teaching and learning environment. The course applies collaborative online international learning principles and is addressed to graduate students of universities from Brazil, Germany, Mozambique, and Kosovo.

Landscapes of cellular phenotypic diversity in breast cancer xenografts and their impact on drug response.

The heterogeneity of breast cancer plays a major role in drug response and resistance and has been extensively characterized at the genomic level. Here, a single-cell breast cancer mass cytometry (BCMC) panel is optimized to identify cell phenotypes and their oncogenic signalling states in a biobank of patient-derived tumour xenograft (PDTX) models representing the diversity of human breast cancer. The BCMC panel identifies 13 cellular phenotypes (11 human and 2 murine), associated with both breast cancer subtypes and specific genomic features.

Planning for health sector reform in post-conflict situations: Kosovo 1999-2000.

The restoration and development of health care systems in post-conflict situations and complex emergencies are attracting attention. Kosovo is unique in being a post-conflict situation, in a former socialist country, with an unclear political future, under temporary UN administration. The World Health Organization (WHO) led a process of developing a health policy framework for the emergency period that included elements of health sector reform, a somewhat controversial initiative.
