Abstract Objectives Gliomas are highly aggressive neuroepithelial-layer malignancies. Hypoxia-inducible factor 1α (HIF-1α) was revealed to be upregulated in gliomas under hypoxia. Nevertheless, its role glioma cells remains elusive. We attempted clarify the molecular mechanism of HIF-1 underlying glioma. Methods Cellular models were established mimic characteristics RT‒qPCR used detect HIF-1α a...

Alpha Hope is a dietary supplement containing pyrroloquinoline quinone and elemental magnesium, which produces molecular hydrogen (H2 gas) when dissolved in water. We determined the impact of on Nrf-2, peroxisome proliferator-activated receptor-gamma coactivator (PGC-1α), citrate synthase (CS) activity C2C12 myoblasts. was titrated to three concentrations (PQQ) (10 nM, 100 1000 nM) treated for ...

Abstract The increasing frequency and duration of marine heatwaves attributed to climate change threatens coastal elasmobranchs may exacerbate existing anthropogenic stressors. While the elasmobranch stress response has been well studied, role unique corticosteroid—1α-hydroxycorticosterone (1α-OHB)—in energy balance is not understood. Therefore, 1α-OHB’s utility as a biomarker in conservation p...

Background: Tumor microenvironment is an active factor participating in immunoregulation, thereby preventing immunosurveillance and limiting the efficacy of anticancer therapies. Hypoxia as a major characteristic of solid tumors causes the expression of Hypoxia-Inducible Factor-1α (HIF-1α). This is a transcription factor that mediates hypoxic responses of tumor cells and involves in the express...

Proinflammatory cytokines secreted from adipose tissue contribute to the morbidity associated with obesity. IL-1α is one of the proinflammatory cytokines; however, it has not been clarified whether IL-1α may also cause obesity. In this study, we investigated whether polymorphisms in IL-1α contribute to human obesity. A total of 260 obese subjects were genotyped for IL-1α C-889T (rs1800587) and ...

Hypoxia-inducible factor 1α (HIF-1α) is a transcription factor that plays a key role in regulating the adaptive response to hypoxia. HIF-1α is stabilised during hypoxia and, after dimerisation with hypoxia-inducible factor 1β (HIF-1β), triggers the expression of various genes involved in cell cycle control and energy metabolism associated with cell survival. However, HIF-1α also regulates the e...

Hypoxia-inducible factor-1α (HIF-1α) is a master transcriptional regulator of cellular response to hypoxia. In normoxia, HIF-1α is degraded through the prolyl hydroxylase (PHD) and von Hippel-Lindau (VHL) ubiquitination pathway. However, it is unknown whether PHD and VHL exert their enzymatic activities on HIF-1α separately or as a multiprotein complex. Here, we show that phospholipase D1 (PLD1...

The transcriptional coactivator peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) regulates expression of genes for metabolism and muscle fiber type. Recently, a novel splice variant of PGC-1α (NT-PGC-1α, amino acids 1-270) was cloned and found to be expressed in muscle. Here we use Flag-tagged NT-PGC-1α to examine the subcellular localization and regulation of NT-PGC-1α in s...
