Hypoxia-inducible-factor (HIF)-mediated expression of pro-angiogenic genes under hypoxic conditions is the fundamental cause of pathological neovascularization in retinal ischemic diseases and cancers. Recent studies have shown that histone lysine demethylases (KDMs) play a key role in the
OBJECTIVE
Hypoxia-inducible factor-1α (HIF-1α) plays a pivotal role in the reaction of a tumour to hypoxia. In this study, we examined the inhibitory effect of a natural compound, honokiol, on HIF-1α activity and tumour growth in combination with radiation.
METHODS
The inhibitory effect of honokiol
Obstructive sleep apnea hypopnea syndrome (OSAHS) is associated with glucose intolerance, insulin resistance and type 2 diabetes mellitus (T2DM). Although several studies have revealed that intermittent hypoxia (IH) in OSAHS may further aggravate pancreatic β cell damage and promote the evolution of
Pathological activation of the hypoxia-inducible-factor (HIF) pathway leading to expression of pro-angiogenic genes, such as vascular endothelial growth factor (VEGF), is the fundamental cause of neovascularization in ocular ischemic diseases and cancers. We have shown that pure honokiol inhibits
Hemangioblastomas of the retina, central nervous system, and kidney are observed in patients with mutations in the von Hippel-Lindau (VHL) tumor suppressor gene. Mutations in the VHL lead to constitutive activation of hypoxia-inducible-factor (HIF) pathway. HIF-mediated expression of pro-angiogenic
Aberrant activation of the hypoxia inducible factor (HIF) pathway is the underlying cause of retinal neovascularization, one of the most common causes of blindness worldwide. The HIF pathway also plays critical roles during tumor angiogenesis and cancer stem cell transformation. We have recently
OBJECTIVE
Acute respiratory distress syndrome (ARDS) is characterized by acute hypoxemia with diffuse alveolar damage and increased pulmonary microvascular permeability. Honokiol (HKL), the principal active ingredient of Chinese herb magnolia officinalis, protected the lung of experimental ARDS
Abnormal autophagy plays critical roles in the structure and function of the pulmonary vasculature. Cyclophilin A (CyPA) can be secreted from cells in response to hypoxia and oxidative stress, which are involved in inducing autophagy and regulating the function of endothelial cells in pulmonary
We aimed at investigating the effect of honokiol on heatstroke in an experimental rat model. Sprogue-Dawley rats were divided into 3 groups: normothermic diabetic rats treated with vehicle solution (NTDR+V), heatstroke-diabetic rats treated with vehicle (HSDR+V), and heatstroke rats treated with
Aims: TNF receptor-associated protein 1 (TRAP1), the mitochondrial paralog of the heat shock protein 90 (Hsp90) family of molecular chaperones, is required for neoplastic growth in several tumor cell models, where it inhibits succinate dehydrogenase (SDH) activity, thus favoring
Honokiol (HKL) is a natural low-molecular-weight biphenolic compound derived from the bark of magnolia trees. Previous studies indicate that HKL exerts potent cardioprotective effects on ischemia/reperfusion (I/R) injury; however, evidence of the further relationship between HKL posttreatment and
Glioblastoma responses to bevacizumab are invariably transient with acquired resistance. We profiled paired patient specimens and bevacizumab-resistant xenograft models pre- and post-resistance towards the primary goal of identifying regulators whose targeting could prolong the therapeutic window,
