Epigenetic Modulation in Parkinson’s Disease and Potential Treatment Therapies

In the recent past, huge emphasis has been given to the epigenetic alterations of the genes responsible for the cause of neurological disorders. Earlier, the scientists believed somatic changes and modifications in the genetic makeup of DNA to be the main cause of the neurodegenerative diseases. With the increase in understanding of the neural network and associated diseases, it was observed that alterations in the gene expression were not always originated by the change in the genetic sequence. For this reason, extensive research has been conducted to understand the role of epigenetics in the pathophysiology of several neurological disorders including Alzheimer’s disease, Parkinson’s disease and, Huntington’s disease. In a healthy person, the epigenetic modifications play a crucial role in maintaining the homeostasis of a cell by either up-regulating or down-regulating the genes. Therefore, improved understanding of these modifications may provide better insight about the diseases and may serve as potential therapeutic targets for their treatment. The present review describes various epigenetic modifications involved in the pathology of Parkinson’s Disease (PD) backed by multiple researches carried out to study the gene expression regulation related to the epigenetic alterations. Additionally, we will briefly go through the current scenario about the various treatment therapies including small molecules and multiple phytochemicals potent enough to reverse these alterations and the future directions for a better management of PD.

     

Mixed PGPR consortium: an effective modulator of antioxidant network for management of collar rot in cauliflower

Abstract

Sclerotinia sclerotiorum is a cosmopolitan fungal pathogen causing stem and collar watery soft rot of cauliflower. Previous management of this disease with chemical pesticides caused hazardous results which lead to use of more eco-friendly microbial approaches. In the present study, consortia of Trichoderma harzianum TNHU27 and Pseudomonas aeruginosa PJHU15 were assessed for their ability in controlling Sclerotinia rot in cauliflower. The seedlings of cauliflower were challenged singly and in consortium with these two compatible microbes. The plants were evaluated upon challenge inoculation with S. sclerotiorum for changes in total phenolic content, the activity of defense and antioxidative enzymes. The microbial consortium comprising of T. harzianum and P. aeruginosa significantly enhanced the defense responses of the plant in comparison to pathogen challenged and unchallenged control. The study elucidates that plant beneficial microbes in the consortium may provide superior protection by induction of faster and enhanced defense responses in comparison to unchallenged and single microbe challenged plants under pathogen challenged conditions.
