Cholesterol and HIF-1α: Dangerous Liaisons in Atherosclerosis

open access: yesFrontiers in Immunology, 2022
HIF-1α exerts both detrimental and beneficial actions in atherosclerosis. While there is evidence that HIF-1α could be pro-atherogenic within the atheromatous plaque, experimental models of atherosclerosis suggest a more complex role that depends on the ...

HIF-1α inhibition reduces nasal inflammation in a murine allergic rhinitis model. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Hypoxia-inducible factor 1α (HIF-1α) is an important regulator of immune and inflammatory responses. We hypothesized that nasal allergic inflammation is attenuated by HIF-1α inhibition and strengthened by HIF-1α stabilization.

Hypoxia stimulates neural stem cell proliferation by increasing HIF"‘1α expression and activating Wnt/β-catenin signaling [PDF]

open access: yesCellular and Molecular Biology, 2017
Evidence indicates that after brain injury, neurogenesis is enhanced in regions such as hippocampus, striatum, and cortex. To study the role of hypoxia-inducible factor-1 (HIF"‘1α) and Wnt signaling in cerebral ischemia/hypoxia-induced proliferation of neural stem cells (NSCs), we investigated the proliferation of NSCs, expression of HIF"‘1α, and ...

Synergistic inhibition of Wnt pathway by HIF-1α and osteoblast-specific transcription factor osterix (Osx) in osteoblasts. [PDF]

open access: yesPLoS ONE, 2012
Osterix (Osx) is an osteoblast-specific transcription factor required for osteoblast differentiation. Inhibition of Wnt pathway by Osx highlights the potential for feedback control mechanisms involved in bone formation.

Effect of HIF-1αsiRNA-linked AuNRs on radiotherapy of nasopharyngeal carcinoma

open access: yesCellular and Molecular Biology, 2020
The radiation sensitivity of tumor cells is closely related to tumor cell hypoxia. Hypoxia-inducible factor-1α (HIF-1α) is considered a key transcription factor which regulates the sensitivity of hypoxic tumor cells to radiotherapy. On the other hand, some studies have shown that gold nanomaterials improve radiation sensitivity.

Insulin regulates hypoxia-inducible factor-1α transcription by reactive oxygen species sensitive activation of Sp1 in 3T3-L1 preadipocyte. [PDF]

open access: yesPLoS ONE, 2013
Oxygen sensing transcription factor HIF-1 is activated due to accumulation of regulatory subunit HIF-1α by posttranslational stability mechanism during hypoxia or by several other stimuli even in normoxia.

Intranasal deferoxamine attenuates synapse loss via up-regulating the P38/HIF-1α pathway on the brain of APP/PS1 transgenic mice [PDF]

open access: yesFrontiers in Aging Neuroscience, 2015
The widely recognized neuroprotective effect of iron chelators is contributed by their ability to prevent reactive oxygen species (ROS) generation via the Fenton reaction, which sequesters redox-active Fe. An additional neuroprotective mechanism of iron-chelating compounds is to regulate the transcriptional activator hypoxia-inducible factor 1α (HIF-1α)

HIF-1α inhibits Wnt signaling pathway by activating Sost expression in osteoblasts. [PDF]

open access: yesPLoS ONE, 2013
The nature of the cellular and molecular mechanisms for the transition of avascular cartilage replacement with bone during endochondral ossification remains poorly understood. One of the driving forces is hypoxia.

Hypoxia-inducible factor-1 alpha as a therapeutic target for primary effusion lymphoma. [PDF]

open access: yesPLoS Pathogens, 2017
Primary effusion lymphoma (PEL) is an aggressive B-cell lymphoma with poor prognosis caused by Kaposi's sarcoma-associated herpesvirus (KSHV). Previous studies have revealed that HIF-1α, which mediates much of the cellular response to hypoxia, plays an ...
