Glioblastoma multiforme (GBM), the most malignant type of brain tumour, is regulated mainly by a hypoxic microenvironment. Previous studies have focused mainly on the effects of hypoxia inducible factor-1α (HIF-1α) or hypoxia inducible factor-2α (HIF-2α)

Suppression of hepcidin transcript levels is not mediated by HIF-1α or HIF-2α.
(A) SiRNA-mediated knock-down of HIF-1α (1α) or HIF-2α (2α) did not attenuate the down-regulation of hepcidin mRNA levels in HepG2 cells after 16 h of stimulation; luciferase (luc) siRNA served as negative control.

This article aims to elucidate the biological mechanisms of bone repair and the evolution of material design, highlighting key cellular and molecular processes. It further proposes strategies and prospects for programmable bio‐interactive materials, which enable precisely guided bone tissue regeneration by dynamically regulating cell behavior and the ...

Effects of HIF-1α and HIF-2α inhibition by si-RNA on PKM2 expression.
PC3 and LNCaP cells were transfected and cultured for 24 h in normoxia 20% O2 or hypoxia 0.1% O2. (A) PKM2 mRNA expression detection and quantification by qRT-PCR after treatment of cells with si-HIF-1α or si-HIF-2α (n = 4, Mean ± SEM, *** P § P < 0.05 ...

A PROTAC‐functionalized protein/DNA‐integrated nanoantigen platform is developed to enhance dendritic cell vaccine potency. By combining a VHL‐recruiting peptide‐modified antigen with a sustained expression plasmid within CaCO3 nanoparticles, this system amplifies cross‐presentation, promotes DC maturation, and elicits robust Th1 and CTL responses ...

hypoxia-inducible factors activate CD133 promoter through ETS family transcription factors.
CD133 is a cellular surface protein that has been reported to be a cancer stem cell marker, and thus it is considered to be a potential target for cancer treatment. However, the mechanism regulating CD133 expression is not yet understood.

Hif-2α promotes degradation of Mammalian peroxisomes by selective autophagy
Peroxisomes play a central role in lipid metabolism, and their function depends on molecular oxygen. Low oxygen tension or von Hippel-Lindau (Vhl) tumor suppressor loss is known to stabilize hypoxia-inducible factors alpha (Hif-1α and Hif-2α) to mediate ...

Chemotherapy-mediated p53-dependent DNA damage response in clear cell renal cell carcinoma: role of the mTORC1/2 and hypoxia-inducible factor pathways [PDF]
The DNA-damaging agent camptothecin (CPT) and its analogs demonstrate clinical utility for the treatment of advanced solid tumors, and CPT-based nanopharmaceuticals are currently in clinical trials for advanced kidney cancer; however, little is known ...

A nanomodulator called L‐Arginine/lificiguat@Copper‐hollow Prussian blue@Calcium phosphate nanoparticles is constructed to launch a self‐amplifying “avalanche effect” in tumor cells. The ensuing cascade, triggered by the acidic tumor microenvironment and near‐infrared light, induces calcium overload, generates a reactive oxygen species and reactive ...
