Insights

This study reveals that the pseudogene URAHP, a long noncoding RNA, is upregulated in preeclampsia (PE) placentae and influences cell proliferation, offering a potential new therapeutic target for PE.

Area of Science:

  • Reproductive biology
  • Genomics
  • Molecular medicine

Background:

  • Preeclampsia (PE) is a pregnancy-specific disorder with no effective treatments.
  • Long noncoding RNAs (lncRNAs) are increasingly recognized for their roles in disease pathogenesis.
  • The pseudogene URAHP shows elevated expression in PE placentae.

Purpose of the Study:

  • To investigate the role of the lncRNA URAHP in preeclampsia.
  • To explore the regulatory mechanisms and functional impact of URAHP in placental cells.
  • To identify potential therapeutic targets for preeclampsia.

Main Methods:

  • Differential expression analysis of lncRNAs and mRNAs in normal pregnancy (NP) and PE placentae using microarray.
  • Validation of URAHP expression via quantitative real-time PCR (qRT-PCR).
  • Functional assays (CCK-8, 3D colony formation) to assess URAHP's effect on cell proliferation.
  • Gene coexpression analysis and western blotting to investigate URAHP and KISS1R interactions.

Main Results:

  • High-throughput sequencing identified 675 differentially expressed lncRNAs and 205 differentially expressed genes between PE and NP samples.
  • URAHP expression was significantly increased in PE placentae compared to NP.
  • URAHP downregulation affected cell proliferation, while URAHP overexpression promoted it; URAHP and KISS1R were found to be coexpressed.

Conclusions:

  • The pseudogene URAHP is implicated in preeclampsia for the first time.
  • URAHP represents a novel molecular target for preeclampsia treatment strategies.

The Ras Gene02:38

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.

Hormonal Regulation01:33

Hormonal Regulation

The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

The Unfolded Protein Response01:37

The Unfolded Protein Response

The ER is the hub of protein synthesis in a cell. It has robust systems to quality control protein folding and also for degradation of terminally misfolded proteins. Under normal conditions, a small proportion of misfolded proteins that cannot be salvaged need to be transported to the cytoplasm by the ER-associated degradation or ERAD pathways. However, if the ERAD cannot handle the misfolded proteins, the cell activates the unfolded protein response or UPR to adjust the protein folding...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Cell Specific Gene Expression01:58

Cell Specific Gene Expression

Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

Regulation of the Unfolded Protein Response

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...
