Scientific investigation of non-coding RNAs in mitochondrial epigenetic and aging disorders: Current nanoengineered approaches for their therapeutic improvement.

Abstract

Genetic control is vital for the growth of cells and tissues, and it also helps living things, from single-celled organisms to complex creatures, maintain a stable internal environment. Within cells, structures called mitochondria act like tiny power plants, producing energy and keeping the cell balanced. The two primary categories of RNA are messenger RNA (mRNA) and non-coding RNA (ncRNA). mRNA carries the instructions for building proteins, while ncRNA does various jobs at the RNA level. There are different kinds of ncRNA, each with a specific role. Some help put RNA molecules together correctly, while others modify other RNAs or cut them into smaller pieces. Still others control how much protein is made from a gene. Scientists have recently discovered many more ncRNAs than previously known, and their functions are still being explored. This article analyzes the RNA molecules present within mitochondria, which have a crucial purpose in the operation of mitochondria. We'll also discuss how genes can be turned on and off without changing their DNA code, and how this process might be linked to mitochondrial RNA. Finally, we'll explore how scientists are using engineered particles to silence genes and develop new treatments based on manipulating ncRNA.
