The mechanisms by which modulation of gene transcription occurs are only partially resolved, and this is the subject of considerable research effort, especially with respect to the family of transcription factors, i.e. peroxisome proliferator-activated receptors (PPARs), in plump videos the nuclei of cells. The effects can be highly specific, different fatty acids binding to or activating different types of PPAR. Similarly, in bacteria, it has been demonstrated that the bacterial fatty acid transport plump videos and trafficking system leads to fatty acid-responsive regulation of gene expression. Free fatty acids are powerful detergents and will inhibit very many enzymes systems in a non-specific manner. |

| In this way, they can substitute for the second messengers ahrq of the inositide pathways. Fatty acids are effective also in operating at specific ahrq intracellular locations reversibly to amplify or otherwise modify signals. For example, they influence the activities of protein kinases, phospholipases, G-proteins, adenylate and guanylate cyclases, and many other metabolic processes. Part of the action of fatty acid may occur indirectly via metabolism of arachidonic acid to eicosanoids. On the other hand, there is much evidence that fatty acids per se are messengers that mediate the responses of the cell to extracellular ahrq signals. Many of these reactions are specific to particular fatty acids. For example, polyunsaturated fatty acids, including docosahexaenoic and arachidonic acids, bind to the retinoid X receptor and induce activation. Some related processes appear to occur in plants. In addition in animal tissues, polyunsaturated fatty acids are involved in regulating gene expression, mainly targeting genes that encode proteins with roles in fatty acid transport or metabolism. |
