Activation of hypoxia inducible factor 1 is a general phenomenon in infections with human pathogens

, 2010
Background: Hypoxia inducible factor (HIF)-1 is the key transcriptional factor involved in the adaptation process of cells and organisms to hypoxia. Recent findings suggest that HIF-1 plays also a crucial role in inflammatory and infectious diseases ...

Effects of Stem Cell Factor on Hypoxia-Inducible Factor 1 Alpha Accumulation in Human Acute Myeloid Leukaemia and LAD2 Mast Cells [PDF]

, 2011
Stem cell factor (SCF) is a hematopoietic growth factor that exerts its activity by signalling through the tyrosine kinase receptor known as Kit or CD117.

Hypoxia activates IKK-NF-κB and the immune response in Drosophila melanogaster [PDF]

, 2014
Hypoxia, or low oxygen availability, is an important physiological and pathological stimulus for multicellular organisms. Molecularly, hypoxia activates a transcriptional programme directed at restoration of oxygen homoeostasis and cellular survival ...

Hypoxia induces oncogene yes-associated protein 1 nuclear translocation to promote pancreatic ductal adenocarcinoma invasion via epithelial–mesenchymal transition

Tumor Biology, 2017
Pancreatic ductal adenocarcinoma is one of the most lethal cancers. The Hippo pathway is involved in tumorigenesis and remodeling of tumor microenvironments.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

The RabGEF ALS2 is a hypoxia inducible target associated with the acquisition of aggressive traits in tumor cells

Scientific Reports, 2020
Tumor hypoxia and the hypoxia inducible factor-1, HIF-1, play critical roles in cancer progression and metastasis. We previously showed that hypoxia activates the endosomal GTPase Rab5, leading to tumor cell migration and invasion, and that these events ...

Tale of two transcription factors: NF-кB and HIF crosstalk [PDF]

, 2013
Hypoxia-inducible factor is a key transcriptional factor involved in the cellular response to low levels of oxygen, hypoxia. Moreover, hypoxia-inducible factor has been recently associated with a role in inflammation and immunity.

Expression of hypoxia-inducible factor-1α in human periodontal tissue

, 2011
Background: Hypoxia-inducible factor (HIF)-1 is a key transcription factor responding to hypoxia. It is composed of an oxygen-sensitive α subunit (HIF-1α) and a constitutively expressed β subunit.

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

Molecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

Impairment of HIF-1α-mediated metabolic adaption by NRF2-silencing in breast cancer cells

Redox Biology, 2019
Hypoxia, a common element in the tumor environment, leads to Hypoxia-Inducible Factor-1α (HIF-1α) stabilization to modulate cellular metabolism as an adaptive response. In a previous study, we showed that inhibition of the nuclear factor erythroid 2-like-
