Genomic activation is defined as the binding of a nuclear receptor to a response element, which activates the transcription of certain genes.
Active retinoid receptors consist of RAR/RXR heterodimers, which activate the transcription of many target genes by binding retinoic acid responsive elements in promoter and/or enhancer regions.
Activating the calcium/calmodulin-dependent protein kinase I and IV, which activate many transcription factors such as Nur-related factor 1 (nerve), nerve growth factor induced clone B (NGFIB), activating transcription factor 1 (and1), and cyclic AMP (cAMP) response element binding protein 1 (CREB1).
The other element is the adjuvant, which activates elements of the innate immune system to in turn license B and T cells to become activated.
Our previous studies showed that a 2.3- or a 0.6-kb genomic fragment of the MK gene contained cis-acting elements, which could activate an exogenous gene preferentially in tumours (Miyauchi et al, 2001; Yoshida et al, 2002).
In Xenopus, progesterone triggers Cdk1-dependent phosphorylation of the cytoplasmic polyadenylation element binding protein, which activates the GLD-2 cytoplasmic poly(A) polymerase to promote translation (see Ivshina et al. 2014 for a review).
Summing up, there are different elements which are activated as resilience strategies to adapt at times of crisis: access to and use of ethnic and class resources; sectorial specialisation with disregard of a parallel diversification; share of social capital through networks and engagement in community associations.
IFNλ expression is controlled by pattern recognition receptor PRR activation, which activates and mobilizes IRF3 and IRF7, which in turn bind to the interferon-stimulated response elements (ISREs) of these genes, along with several other genes.
Importantly, these factors have been shown to promote phosphorylation of transcription factor cAMP response element (CREB) at its Ser133, which activates specific gene expression with recruitment of its transcriptional co-activator CREB binding protein (CBP).
Differentiation is enhanced by sterol regulatory element binding protein-1c (SREBP-1c), which activates PPAR γ transcription (Fajas et al, 1999).
