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...

Transducer Mechanism: Nuclear Receptors01:31

Transducer Mechanism: Nuclear Receptors

Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
RNA Interference01:23

RNA Interference

RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
siRNA - Small Interfering RNAs02:30

siRNA - Small Interfering RNAs

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...

Summary

MicroRNAs (miRNAs) regulate gene expression influenced by estradiol. Aberrant miRNA expression is linked to estrogen-related cancers, highlighting their role in hormone action and disease.

Area of Science:

  • Molecular Biology
  • Genetics
  • Endocrinology

Background:

  • MicroRNAs (miRNAs) are short, noncoding RNAs regulating gene expression by targeting messenger RNAs (mRNAs).
  • Estradiol (E(2)) and estrogen receptor (ER) ligands modulate miRNA expression across various tissues.
  • Dysregulated miRNA expression is associated with estrogen-dependent cancers like breast and endometrial cancer.

Purpose of the Study:

  • To explore the role of estrogen-regulated miRNA expression in cellular processes.
  • To identify target genes regulated by these miRNAs.
  • To understand the involvement of miRNAs in estrogen action and related diseases.

Main Methods:

  • Analysis of miRNA expression patterns in response to E(2) and ER ligands.
  • Bioinformatic prediction and experimental validation of miRNA targets.
