Over the past few decades, large food banks that collect, warehouse, and redistribute food have become institutionalized across Europe. Although food banks gained increased visibility as important food relief mechanisms during the covid pandemic in 2020 and 2021, the crisis also highlighted their structural weaknesses and the fragility of the charity-based emergency food system. In particular, many European food banks faced higher costs, lower food stocks, uneven food donations, and lower numbers of volunteers and personnel as demand for food relief increased sharply.

Osteosarcoma (OS) is a highly malignant bone tumour that has seen little improvement in treatment modalities in the past 30 years. Understanding what molecules contribute to OS biology could aid in the discovery of novel therapies. Extracellular vesicles (EVs) serve as a mode of cell-to-cell communication and have the potential to uncover novel protein signatures.

Osteosarcoma (OS) is an aggressive mesenchymal cell tumor that carries a poor long-term prognosis. Despite definitive surgery for the primary tumor and adjuvant chemotherapy, pulmonary metastasis is common and is the primary cause of morbidity. To improve outcomes for patients, we have developed and optimized a phenotypic screen for drugs that may target OS disseminated tumor cells (DTCs) and inhibit their metastatic outbreak rather than merely screening for cytotoxic activity against proliferating cells, as is commonly conducted in conventional drug discovery approaches.

Article Synopsis
  • - Cancer survivors often fear recurrence, especially since metastasis is responsible for about 90% of cancer deaths, highlighting the need for improved strategies to prevent metastatic recurrence.
  • - The review explores several methods to target dormant disseminated tumor cells (DTCs) that may cause cancer to return, including keeping them inactive, promoting dormancy, and making them more vulnerable to therapies.
  • - It also discusses the potential for using already approved drugs, identifies biomarkers for high-risk patients, and critiques current clinical trial designs aimed at addressing dormant DTCs.

Background: Next generation sequencing (NGS) provides a key technology for deciphering the genetic underpinnings of human diseases. Typical NGS analyses of a patient depict tens of thousands non-reference coding variants, but only one or very few are expected to be significant for the relevant disorder. In a filtering stage, one employs family segregation, rarity in the population, predicted protein impact and evolutionary conservation as a means for shortening the variation list.
