Insights

Mitochondrial microRNAs (mitomiRs) regulate cellular processes and the mitochondrial genome. Emerging research suggests their involvement in neurodegenerative diseases like Alzheimer's and Parkinson's.

Area of Science:

  • Molecular Biology
  • Neuroscience
  • Genetics

Background:

  • MicroRNAs (miRNAs) are key regulators of cellular functions, with over 2000 identified in mammals.
  • A subset, known as mitochondrial microRNAs (mitomiRs), are localized to human mitochondria.
  • Over 400 mitomiRs have been identified, influencing the mitochondrial genome's translational activity.

Purpose of the Study:

  • To review recent findings on the role of mitomiRs in neurodegenerative diseases.
  • To explore the connection between mitomiRs and age-related neurodegenerative conditions.
  • To highlight the functional significance of mitomiRs in mitochondrial regulation.

Main Methods:

  • Literature review of current research on mitomiRs and neurodegeneration.
  • Analysis of studies investigating mitomiR function in Alzheimer's, Parkinson's, and Huntington's disease.
  • Discussion of the mechanisms by which mitomiRs affect the mitochondrial genome.

Main Results:

  • Evidence suggests mitomiRs play a role in the pathogenesis of neurodegenerative diseases.
  • MitomiRs are implicated in regulating mitochondrial gene expression relevant to aging and disease.
  • The specific functions and disease relevance of many mitomiRs remain under investigation.

Conclusions:

  • MitomiRs represent a novel area of research in neurodegenerative disease etiology.
  • Further investigation into mitomiR function is crucial for understanding and potentially treating these conditions.
  • MitomiRs offer potential therapeutic targets for age-related neurodegenerative disorders.

Mitochondria

Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Mitochondrial Membranes01:45

Mitochondrial Membranes

A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...

Translocation of Proteins into the Mitochondria01:19

Translocation of Proteins into the Mitochondria

Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...

The Inner Mitochondrial Membrane01:28

The Inner Mitochondrial Membrane

The inner mitochondrial membrane is the primary site of ATP synthesis. The inner membrane domain that forms a smooth layer adjacent to the outer membrane is called the inner boundary membrane. This domain contains membrane transporters that drive metabolites in and out of the mitochondria.  In contrast, the inner membrane network that invaginates into the matrix space is called the cristae membrane. This domain accounts for principle mitochondrial function as it accommodates the protein...

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...
