New Research

In the next two decades epigenetics could revolutionize understanding and treatment of diseases of the central nervous system. New research already demonstrates that manipulation of epigenetic mechanisms in vivo and in vitro can ameliorate a host of pathogenic processes associated with neurodegenerative disorders such as Alzheimer’s disease (AD), Parkinson’s (PD), amyotrophic lateral sclerosis (ALS), Huntington’s (HD), and multiple sclerosis (MS), among others. These advances have come relatively rapidly for a field that is still in its infancy compared to the much longer history of epigenetics in developmental biology. Epigenetic modifications are all-encompassing, from nucleotides to amino acids. They are capable of altering transcriptional to biochemical activity in a consistent manner across thousands of genes and hundreds of biologic pathways, yet they can do so differentially even in individuals or cells with identical gene codes. As such, epigenetic modifications are likely to touch on virtually all the mechanisms described in this book.

Valerianaceae, the sub-family of Caprifoliaceae, contains more than 300 species of annual and perennial herbs, worldwide distributed. Several species are used for their biological properties while some are used as food. Species from the genus Valeriana have been used for their antispasmodic, relaxing, and sedative properties, which have been mainly attributed to the presence of valepotriates, borneol derivatives, and isovalerenic acid. Among this genus, the most common and employed species is Valerianaofficinalis. Although valerian has been traditionally used as a mild sedative, research results are still controversial regarding the role of the different active compounds, the herbal preparations, and the dosage used. The present review is designed to summarize and critically describe the current knowledge on the different plant species belonging to Valerianaceae, their phytochemicals, their uses in the treatment of different diseases with particular emphasis on the effects on the central nervous system. The available information on this sub-family was collected from scientific databases up until year 2020. The following electronic databases were used: PubMed, Scopus, Sci Finder, Web of Science, Science Direct, NCBI, and Google Scholar. The search terms used for this review included Valerianaceae, Valeriana, Centranthus, Fedia, Patrinia, Nardostachys, Plectritis, and Valerianella, phytochemical composition, in vivo studies, Central Nervous System, neuroprotective, antidepressant, antinociceptive, anxiolytic, anxiety, preclinical and clinical studies.

6 Hydroxydopamine

A new strategy for measurement of brain catecholamines was tested in an animal model. [3H]Norepinephrine was infused intravenously in rabbits to label the peripheral norepinephrine pools. The specific activity of urinary 3-methoxy-4-hydroxymandelic acid was consistently higher than that for 3-methoxy-4-hydroxyphenylglycol (MHPG). Central sympathectomy with 6-hydroxydopamine abolished this difference. Using the formula we propose, it is estimated that 30–50% of urinary MHPG originates from the central nervous system.
