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

open access: yesMolecular 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 ...

Pathophysiological Response to Hypoxia — From the Molecular Mechanisms of Malady to Drug Discovery: Hypoxia-Inducible Factor-1 (HIF-1)-Active Cells as a Target for Cancer Therapy

open access: yesJournal of Pharmacological Sciences, 2011
The microenvironment of solid tumors is characterized by low pO2 that is well below physiological levels. Intratumoral hypoxia is a major factor contributing to cancer progression and is exacerbated as a result of oxygen consumption by rapidly ...

Hypoxia-Induced Autophagy Is Involved in Radioresistance via HIF1A-Associated Beclin-1 in Glioblastoma Multiforme

open access: yesHeliyon, 2023
Radioresistance is the major factor of glioblastoma multiforme (GBM) treatment failure and relapse. Hypoxia and autophagy are linked to radioresistance and poor prognosis in solid tumors, but mechanisms remain unknown.

Hypoxia‐inducible factor 1 and cancer pathogenesis [PDF]

open access: yesIUBMB Life, 2008
AbstractHypoxia‐inducible factor 1 (HIF‐1) is a transcriptional activator that mediates adaptive responses to hypoxia. HIF‐1 activity is increased in the majority of human cancers as a result of genetic alterations and intratumoral hypoxia. HIF‐1 activates the transcription of genes that increase O2 availability by stimulating angiogenesis or that ...

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

open access: yes, 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.

Hypoxia-inducible factor 1 alpha in oral squamous cell carcinoma and its relation to prognosis [PDF]

open access: yes, 2009
The aim of this study was to investigate the correlation between the expression of hypoxia-inducible factor 1 alpha (HIF-1 alpha) and proliferative activity in tumor cells, lymph node metastasis, as well as prognosis in patients with oral squamous cell ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Hypoxia inducible factor 1 (HIF-1) and cardioprotection [PDF]

open access: yesActa Pharmacologica Sinica, 2010
Since its discovery in early 1990s, hypoxia inducible factor 1 (HIF-1) has been increasingly recognized for its key role in transcriptional control of more than a hundred genes that regulate a wide-spectrum of cellular functional events, including angiogenesis, vasomotor control, glucose and energy metabolism, erythropoiesis, iron homeostasis, pH ...

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Expression of Hypoxia-inducible factor 1-α and Vascular endothelial growth factor-C in locally advanced breast cancer patients

open access: yesClinics, 2011
BACKGROUND: Locally advanced breast cancers are more prevalent in underdeveloped countries. Targeted therapy has been improved to identify hallmarks that are specific to these subtypes of tumors.
