TLDR
There are new approaches to enforce necrotic cell death and tumour regression by targeting tumour metabolism and pHi-control systems.Abstract:
Tumour cells emerge as a result of genetic alteration of signal circuitries promoting cell growth and survival, whereas their expansion relies on nutrient supply. Oxygen limitation is central in controlling neovascularization, glucose metabolism, survival and tumour spread. This pleiotropic action is orchestrated by hypoxia-inducible factor (HIF), which is a master transcriptional factor in nutrient stress signalling. Understanding the role of HIF in intracellular pH (pH(i)) regulation, metabolism, cell invasion, autophagy and cell death is crucial for developing novel anticancer therapies. There are new approaches to enforce necrotic cell death and tumour regression by targeting tumour metabolism and pH(i)-control systems.read more

Snail, ZEB and bHLH factors in tumour progression: an alliance against the epithelial phenotype?
TL;DR: The identification of Snail, ZEB and some basic helix-loop-helix factors as inducers of epithelial–mesenchymal transition (EMT) and potent repressors of E-cadherin expression has opened new avenues of research with potential clinical implications.

Carbonic anhydrases: novel therapeutic applications for inhibitors and activators
TL;DR: The biological rationale for the novel uses of inhibitors or activators of CA activity in multiple diseases is discussed, and progress in the development of specific modulators of the relevant CA isoforms is highlighted, some of which are now being evaluated in clinical trials.

Reactive oxygen species in cancer
Geou Yarh Liou,Peter Storz +1 more
TL;DR: The generation of ROS within tumour cells, their detoxification, their cellular effects, as well as the major signalling cascades they utilize are discussed, but also an outlook on their modulation in therapeutics is provided.

Tumor Cell Metabolism: Cancer's Achilles' Heel
TL;DR: The peculiarities of tumor cell metabolism are reviewed to discuss the alterations in signal transduction pathways and/or enzymatic machineries that account for metabolic reprogramming of transformed cells.

The biology of VEGF and its receptors.
TL;DR: Vascular endothelial growth factor (VEGF) is a key regulator of physiological angiogenesis during embryogenesis, skeletal growth and reproductive functions and is implicated in pathologicalAngiogenesis associated with tumors, intraocular neovascular disorders and other conditions.

Targeting HIF-1 for cancer therapy
TL;DR: Hypoxia-inducible factor 1 (HIF-1) activates the transcription of genes that are involved in crucial aspects of cancer biology, including angiogenesis, cell survival, glucose metabolism and invasion.

TL;DR: It is shown that the interaction between human pVHL and a specific domain of the HIF-1α subunit is regulated through hydroxylation of a proline residue by an enzyme the authors have termed Hif-α prolyl-hydroxylase (HIF-PH).

TL;DR: The unexpected finding that loss of a single VEGF allele is lethal in the mouse embryo between days 11 and 12 was reported, and angiogenesis and blood-island formation were impaired, resulting in several developmental anomalies.
