This change was mediated by a tissue-specific transcription mechanism.
These results suggest that many late-expressed miRNAs mediate target non-coherence in a tissue-specific and functional manner.
Although IFN-I induction has been extensively studied using macrophages and dendritic cells, IFN-Is are also produced by tissue resident cells and play a tissue-specific role in mediating antiviral innate immunity and regulating immune homeostasis [ 2, 8].
Whole genome approaches using microarray platforms have identified more extensive gene sets that can predict a short interval to distant metastases (that is, a poor prognosis signature) [ 10, 11] or have identified gene sets that mediate metastasis from a specific primary tissue to a tissue-specific host site [ 12, 13].
Thereby, MSC exhibit a tissue-specific functional biodiversity which is mediated by direct cell-to-cell communication via adhesion molecule signaling and by a tightly regulated exchange of a multifactorial panel of cytokines, exosomes, and micro RNAs.
To address this question, we manipulated TBPH levels in a tissue-specific manner and focused on Gal4-mediated TBPH knockdown by using UAS-TBPH-RNAi in combination with UAS-Dicer-2 expression, which enhances knockdown efficiency (33).
This further suggests that miRNAs respond to chemical exposure in a tissue-specific manner and that the toxicity may be mediated, at least in part, through miRNAs.
RASSLs can be expressed in a tissue-specific manner in transgenic mice, allowing direct control of Gi-mediated physiological responses such as heart rate [ 14].
The ARFs function as both transcriptional activators and repressors [ 17], and the combination of ARF and Aux/IAA proteins is thought to mediate the tissue-specific effects of auxin [ 18, 19].
These results suggest that selection for nutrient conservation in proteins may be mediated by tissue-specific expression, a possibility that requires further research.
