Summary
Long noncoding RNA TLR8-AS1 exacerbates preeclampsia by increasing STAT1 and TLR8 expression. This study reveals TLR8-AS1 as a potential therapeutic target for preeclampsia progression.
Area of Science:
- Molecular Biology
- Reproductive Medicine
- Genetics
Background:
- Preeclampsia is a complex pregnancy disorder with significant maternal and fetal morbidity.
- The role of long noncoding RNAs (lncRNAs) in preeclampsia pathogenesis is an emerging area of research.
Purpose of the Study:
- To investigate the role of the lncRNA TLR8-AS1 in the regulation of preeclampsia.
- To elucidate the molecular mechanisms underlying TLR8-AS1's function in preeclampsia.
Main Methods:
- Assessed TLR8-AS1 expression in placental tissues from preeclampsia patients and LPS-induced trophoblast cells.
- Utilized lentivirus infection in trophoblast cells to study TLR8-AS1 function.
- Determined interactions between TLR8-AS1, STAT1, and TLR8.
- Validated findings in a rat model of preeclampsia.
Main Results:
- TLR8-AS1 was highly expressed in preeclampsia tissues and cells.
- Overexpression of TLR8-AS1 inhibited trophoblast cell proliferation, migration, and invasion.
- TLR8-AS1 recruited STAT1 to promote TLR8 transcription, aggravating preeclampsia in vivo.
Conclusions:
- TLR8-AS1 aggravates preeclampsia progression by upregulating STAT1 and TLR8 expression.
- TLR8-AS1 is implicated as a key regulator in preeclampsia pathogenesis.

lncRNA - Long Non-coding RNAs
8.7K
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...

Regulation of the Unfolded Protein Response
2.5K
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

The JAK-STAT Signaling Pathway
9.0K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

TGF - β Signaling Pathway
7.5K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...
