Summary
Hormones, particularly estrogen, regulate microRNAs (miRNAs) in the brain, impacting neurogenesis and potentially contributing to neurodegenerative disorders. Understanding these miRNA-hormone interactions is key for future therapeutic strategies.
Area of Science:
- Neuroscience
- Molecular Biology
- Endocrinology
Background:
- Hormone-microRNA (miRNA) links offer non-genetic ways to modify cellular functions.
- miRNA biogenesis, regulated by hormones like estrogen, is crucial for neurogenesis.
- Disruptions in miRNA processing can impact neurological health.
Purpose of the Study:
- To review the biogenesis and functions of miRNAs.
- To discuss general and estrogen-dependent regulation of miRNAs in the brain.
- To highlight the specific roles of miR-29, miR-9, and estrogens in neurological processes.
Main Methods:
- Literature review focusing on hormonal regulation of miRNAs.
- Analysis of miRNA biogenesis pathways.
- Examination of estrogen's influence on neural miRNAs.
Main Results:
- Hormonal regulation of miRNAs occurs at molecular and cellular levels.
- Estrogenic hormones play significant roles in regulating brain miRNAs.
- Specific miRNAs like miR-29 and miR-9 are linked to estrogen's effects in the nervous system.
Conclusions:
- miRNA-hormone interactions are vital for maintaining brain function.
- Dysregulation of estrogen-dependent miRNAs may contribute to neurodegenerative diseases.
- Further research into these pathways could reveal novel therapeutic targets.

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...

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

01:23Regulation of Expression at Multiple Steps
968
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

6.3K
In eukaryotes, transcription and translation are compartmentalized; an mRNA is first synthesized in the nucleus and then selectively transported to the cytoplasm for protein synthesis. Before transport, a pre-mRNA undergoes several steps of post-transcriptional modifications including splicing, 5' capping, and the addition of a poly-adenine tail. Various proteins bind to the pre-mRNA during these modifications. The mRNA transport takes place with the help of multiple proteins playing...

22.9K
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...
