Transcriptional activation of follistatin by Nrf2 protects pulmonary epithelial cells against silica nanoparticle-induced oxidative stress
Silica nanoparticles (SiO2 NPs) cause oxidative stress in respiratory system. Meanwhile, human cells launch adaptive responses to overcome SiO2 NP toxicity. However, besides a few examples, the regulation of SiO2 NP-responsive proteins and their functions in SiO2 NP response remain largely unknown. In this study, we demonstrated that SiO2 NP induced the expression of follistatin (FST), a stress...
متن کاملSequence of stress-induced alterations in indices of synaptic and transcriptional activation in parvocellular neurosecretory neurons.
Immediate-early genes (IEGs) are widely used to mark endocrine hypothalamic neurons that are activated in response to stress, yet their relationship to the transcriptional control of relevant effector molecule expression is unclear. Acute ether stress provokes increased adrenocorticotropic hormone (ACTH) and corticosterone secretion that peaks at 5 and 30 min, respectively, after the challenge....
متن کاملStress-Induced Activation of Heterochromatic Transcription
Constitutive heterochromatin comprising the centromeric and telomeric parts of chromosomes includes DNA marked by high levels of methylation associated with histones modified by repressive marks. These epigenetic modifications silence transcription and ensure stable inheritance of this inert state. Although environmental cues can alter epigenetic marks and lead to modulation of the transcriptio...
متن کاملTranscriptional Pathways in cPGI2-Induced Adipocyte Progenitor Activation for Browning
De novo formation of beige/brite adipocytes from progenitor cells contributes to the thermogenic adaptation of adipose tissue and holds great potential for the therapeutic remodeling of fat as a treatment for obesity. Despite the recent identification of several factors regulating browning of white fat, there is a lack of physiological cell models for the mechanistic investigation of progenitor...
متن کاملActivation of TORC1 transcriptional coactivator through MEKK1-induced phosphorylation.
CREB is a prototypic bZIP transcription factor and a master regulator of glucose metabolism, synaptic plasticity, cell growth, apoptosis, and tumorigenesis. Transducers of regulated CREB activity (TORCs) are essential transcriptional coactivators of CREB and an important point of regulation on which various signals converge. In this study, we report on the activation of TORC1 through MEKK1-medi...
