- Epigenetic Regulation of Learning and Memory: Accumulating evidence suggests that the epigenetic machinery might regulate the formation and stabilization of long-term memory. Answer the following questions: Review and summarize current literature, focusing on the involvement of epigenetic regulation in learning and memory.Describe a potential strategy for the treatment of epigenetic disease.Explain how enhancers work and how they are identified
- Electroconvulsive therapy (ECT) is a reasonable option for intractable depression or schizophrenia, but a mechanism of action has not been established. One credible hypothesis is related to neural plasticity. Below is the neuronal gene expression assay for four genes after ECT, normalized with the Hamilton depression rating scale of 21 items version (HAM-D-21). Which of the following conclusion you may NOT conclude from the data? ECT may convert adult neurons into IPSCs which may divide and differentiate into healthy adult neurons Neural plasticity steadily increases with the number of ECT administration ECT seems to increase the expression of Yamanaka’s four transcription factors ECT may increase neural plasticityEpigenetics may be partially responsible for the childhood epidemic of obesity. Explain.Discuss at least three of the disorders of focusing. What is the complete epigenetic origin which should include the genetic/biological origin and the environment influence related to these disorders of focusing.
