What is the difference berween short hairpin RNAs and microRNAs. How are they synthesized? Mention the chemical modifications of DNA antisense oligonucleotides. Explain how phosphothionate oligonucleotides lead to the degradation mRNAs associated to diseases. How is antisense RNA naturally produced? Explain the action mechanism of the drug Nusinersen. Mention how SMN1 and SMN2 genes regulate Spinal Muscular Atrophy (SMA) and how Nusinersen affects the synthesis of normal SMN protein. Explain the RNA interference (RNAi) pathway. Mention how this pathway can target the degradation of a specific mRNA. Explain the action mechanism of the drug Patisiran on transthyretin TTR)-mediated amyloidosis (hATTR). Provide with an explanation for he reduction in the synthesis of abnormal TTR proteins caused by atisiran.
