Selection and analysis of a mutant cell line defective in the hypoxia-inducible factor-1 alpha-subunit (HIF-1alpha). Characterization of hif-1alpha-dependent and -independent hypoxia-inducible gene expression.

open access: yesThe Journal of biological chemistry, 1998
Hypoxia-inducible expression has been demonstrated for many groups of mammalian genes, and studies of transcriptional control have revealed the existence of hypoxia-responsive elements (HREs) in the cis-acting sequences of several of these genes. These sequences generally contain one or more binding sites for a heterodimeric DNA binding complex termed ...

A Novel tRNA Half mt‐5’‐tiRNA‐Tyr Promotes Colorectal Cancer Proliferation via Inducing HARS2 Succinylation

open access: yesAdvanced Science, EarlyView.
A mitochondria‐derived tRNA half, mt‐5’‐tiRNA‐Tyr, is upregulated in colorectal cancer tissues and plasma and promotes tumor proliferation. It binds HARS2 and promotes CPT1A‐associated HARS2 K91 succinylation, disrupts HARS2–mt‐tRNA‐His association, impairs mitochondrial translation, enhances succinate‐linked metabolic reprogramming, and shows promise ...

Hypoxia helps glioma to fight therapy [PDF]

open access: yes, 2009
Despite major improvements in the surgical management the prognosis for patients bearing malignant gliomas is still dismal. Malignant gliomas are notoriously resistant to treatment and the survival time of patients is between 3-8 years for low-grade and

Hypoxia regulated pathways in urological malignancies

open access: yes, 2009
Introduction: Kidney Cancer accounts for approximately 2% of all new cancer diagnoses inthe UK each year. Patient survival has improved over the past few decades; however themechanisms of this are yet to be fully elucidated.

A Multidimensional Engineering Strategy Reprograms Microglia via Targeted and Sustained‐Release Extracellular Vesicles for Spinal Cord Injury Repair

open access: yesAdvanced Science, EarlyView.
A multifunctional EV‐based nanoplatform (Ang‐TEVs@Gel) was engineered via preconditioning, surface targeting, and ROS‐responsive hydrogel encapsulation to reprogram microglia. This system restored autophagy via miR‐664a‐3p/PIK3CA axis, cleared myelin debris, resolved neuroinflammation, and promoted axon remyelination, ultimately achieving robust motor ...

Effects of Taohong Siwu Decoction on renal protection and ERK1/2/HIF-1α signaling pathway in rats with mesangial proliferative glomerulonephritis

open access: yesLinchuang shenzangbing zazhi, 2022
ObjectiveTo explore the therapeutic effect of Taohong Siwu Decoction (ThSwT) on mesangial proliferative nephritis (MsPGN) in rats and examine its regulatory effect on extracellular regulated protein kinase 1/2 (ERK1/2)/hypoxia inducible factor 1α (HIF-1α)

Chemical Bond‐Orchestrated Energy Depletion to Augment Lung Cancer Chemo‐Immunotherapy

open access: yesAdvanced Science, EarlyView.
This study grafted dichloroacetic acid (DCA) into perylenediimide (PDI) skeleton via ionic or covalent bond to create novel metabolic agent PDIC‐AC and PDIC‐NAC, explicitly elaborated the underlying energy metabolism and therapeutic mechanism, and developed a promising strategy for energy metabolism‐targeting chemo‐immunotherapy by chemical bond ...

Structure-guided design and optimization of small molecules targeting the protein-protein interaction between the von hippel-lindau (VHL) E3 ubiquitin ligase and the hypoxia inducible factor (HIF) alpha subunit with in vitro nanomolar affinities [PDF]

open access: yes, 2014
E3 ubiquitin ligases are attractive targets in the ubiquitin-proteasome system, however, the development of small-molecule ligands has been rewarded with limited success.

Photoactivated Platinum Complexes: Targeting Membrane Proteins and Organelles for Precision Cancer Therapy

open access: yesAngewandte Chemie, EarlyView.
This review highlights an emerging anticancer approach integrating platinum agents into photodynamic therapy (PDT) and photoactivated chemotherapy (PACT) systems, further augmented by cancer cell membrane‐ and organelle‐targeting. By directing photoactivated platinum complexes from nontargeted distribution to cancer cells or defined subcellular sites ...

Klotho‐Derived Peptide 1 Protects against Acute Kidney Injury by Directly Targeting Mitochondrial ATAD3A

open access: yesAdvanced Science, EarlyView.
This study uncovers that KP1, a Klotho‐derived peptide, protects the kidney against acute kidney injury, a clinical syndrome with high morbidity and mortality. KP1 enters tubular epithelial cells via endocytosis, directly interacts with the mitochondrial ATAD3A/HIGD2A complex, thereby preventing cytochrome c release, and caspases activation, and ...
