At the transcriptional level NTCP is regulated by cellular signaling pathways directly or indirectly involving farnesoid X receptor and small heterodimer partner.
First evidence for the control of mitochondrial events by cellular signaling pathways was provided by demonstrating their effect on the expression and function of anti-apoptotic proteins of the Bcl-2 or IAP family [ 77].
In a recent report [[13]] indicated that nanoparticles can damage DNA of cancer cells without actual penetration in the nuclear milieu and they perform such acts by invoking new cellular signalling pathways.
Previous reports have shown that it is able to suppress proliferation, induce apoptosis, and inhibit invasion, angiogenesis, and metastasis in various cancer types in both in vitro and in vivo models by targeting multiple cellular signalling pathways [ 102, 103].
The calcium ion (Ca2+) is a key intracellular messenger and regulates a diverse range of cellular processes by activating or inhibiting cellular signalling pathways and Ca2+-regulated proteins.
Moreover, cell cycle regulatory events resulting in cell cycle arrest and mitochondria-associated apoptosis can be mediated by a number of cellular signalling pathways.
However, the location, synthesis/degradation and transcriptional behaviour can all be modified by signals from a variety of cellular signalling pathways, which are integrated by FOXO as a net response to the total set of modifications (phosphorylations, acetylations and ubiquitinations), that it undergoes.
All these negative effects of absent enteral nutrition can be explained by a distinct change in cellular signalling pathways.
Furthermore, identification of specific ROS protein targets together with compartmentalisation of Nox activity will uncover the unique mechanisms by which Noxs regulate various cellular signalling pathways.
