Ageing Research Reviews
|April 1, 2014
Summary
Aging brains experience cognitive decline and memory loss. Non-coding RNAs (ncRNAs) in the central nervous system may play a crucial role in regulating these age-related changes in memory.
Area of Science:
- Neuroscience
- Molecular Biology
- Genetics
Background:
- Cognitive abilities and memory decline with advancing age.
- The molecular mechanisms underlying age-related memory loss are not fully understood.
- Most of the human genome transcribes into non-coding RNAs (ncRNAs), not protein-coding mRNAs.
Purpose of the Study:
- To review the current understanding of ncRNAs' role in synaptic plasticity, learning, and memory.
- To explore the involvement of ncRNAs in the aging brain and associated memory deficits.
- To discuss future research directions for ncRNAs in the aging process.
Main Methods:
- Literature review of existing research on ncRNAs and aging.
- Analysis of ncRNA functions in the central nervous system.
- Synthesis of current knowledge on ncRNAs in synaptic plasticity and memory.
Main Results:
- Non-coding RNAs are abundant in the central nervous system.
- ncRNAs are implicated in regulating neuronal and synaptic complexity.
- Evidence suggests ncRNAs influence synaptic plasticity, learning, and memory.
Conclusions:
- ncRNAs represent a significant, yet understudied, molecular mechanism in brain aging.
- Further investigation into ncRNAs is crucial for understanding and potentially mitigating age-related memory loss.
- Future research should focus on the specific roles and therapeutic potential of ncRNAs in the aging brain.

2.6K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

2.8K
Neurotransmitters are integral to the brain's communication system, enabling neurons to transmit signals across synapses. This chemical exchange underpins various cognitive functions, including memory processes. The role of neurotransmitters in memory is multifaceted, influencing the encoding, consolidation, and retrieval of memories through their action on different neural circuits.

31.6K
Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...
