lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

10.2K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Nonsense-mediated mRNA Decay02:27

Nonsense-mediated mRNA Decay

12.1K
The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual role, but they need to work in collaboration. Upf1 is an ATP-dependent RNA helicase that unwinds the RNA helix. Because Upf1 can unwind any RNA, Upf2 and Upf3 are required to help Upf1 discriminate between nonsense and normal mRNAs.
Usually, Upf3 binds to an Exon Junction Complex (EJC) at mRNA splice sites. If a ribosome fully translates the mRNA,...

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

MicroRNAs01:22

MicroRNAs

4.3K
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...

Summary

MicroRNAs (miRNAs) are crucial for uterine function and hormonal signaling. Dysregulation of these non-coding RNAs is linked to uterine diseases like endometriosis and leiomyomas.

Area of Science:

  • Reproductive Biology
  • Molecular Endocrinology
  • Genetics

Background:

  • The uterus requires precise hormonal signaling for embryo implantation and reproduction.
  • Non-coding RNAs, particularly microRNAs (miRNAs), play a vital role in uterine development and function.
  • miRNAs are known to modulate the effects of estradiol and progesterone in the uterus.

Purpose of the Study:

  • To review the role, regulation, and function of non-coding RNAs, with a focus on miRNAs.
  • To examine the involvement of miRNAs in normal uterine physiology (endometrium and myometrium).
  • To explore the role of miRNAs in uterine pathologies, including endometriosis and leiomyomas.

Main Methods:

  • Literature review of current research on non-coding RNAs and miRNAs in the uterus.
  • Analysis of studies investigating miRNA expression and function in endometrial and myometrial tissues.
  • Examination of evidence linking miRNA dysregulation to uterine diseases.

Main Results:

  • miRNAs are essential for fine-tuning hormonal actions of estradiol and progesterone in the uterus.
  • Mis-expression of miRNAs is associated with endometrial and myometrial diseases.
  • Specific miRNAs are implicated in the pathogenesis of endometriosis and leiomyomas.

Conclusions:

  • Non-coding RNAs, especially miRNAs, are critical regulators of uterine function and hormonal signaling.
  • Altered miRNA expression contributes to the development of uterine pathologies.
  • Understanding miRNA roles offers potential therapeutic targets for endometriosis and leiomyomas.
