BACKGROUND Aldehyde dehydrogenase 1 (ALDH1) has been characterised as a cancer stem cell marker in different types of tumours. Additionally, it plays a pivotal role in gene regulation and endows tumour cells with augmented chemoresistance. Recently, ALDH1A1 has been described as a prognostic marker in a pancreatic cancer tissue microarray. The aim of this(More)
Hypoxia and HIFs (HIF-1α and HIF-2α) modulate innate immune responses in the setting of systemic inflammatory responses and sepsis. The HIF prolyl hydroxylase enzymes PHD1, PHD2 and PHD3 regulate the mammalian adaptive response to hypoxia; however, their significance in the innate immune response has not been elucidated. We demonstrate in this study that(More)
The prognosis of colorectal cancer (CRC) is closely linked to the occurrence of distant metastases, which putatively develop from circulating tumor cells (CTCs) shed into circulation by the tumor. As far more CTCs are shed than eventually metastases develop, only a small subfraction of CTCs harbor full tumorigenic potential. The aim of this study was to(More)
Xenogeneic or allogeneic chondrocytes hold great potential to build up new cartilage in vivo. However, immune rejection is a major concern for the utility of universal donor-derived cells. In order to verify the reported immune privilege of chondrocytes in vivo, the aim of this study was to assess engraftment of human articular chondrocytes (HAC) in minipig(More)
Pr ecis: This study describes the first universal and specific marker to detect circulating sarcoma cells in the blood, with the capability to detect any type of sarcoma, offering a key prognostic tool to monitor cancer metastasis and relapse in sarcoma patients. Pr ecis: A long noncoding RNA known to be oncogenic is found to promote cell death during(More)
