Insights

MicroRNAs (miRNAs) are crucial for placental development, regulating immune dialogue, trophoblast differentiation, and blood vessel formation. Oxygen levels and imprinted genes significantly influence these miRNA-mediated processes.

Area of Science:

  • Reproductive biology
  • Molecular medicine
  • Developmental biology

Background:

  • MicroRNAs (miRNAs) are key regulators of gene expression with emerging roles in physiology and medicine.
  • Circulating miRNAs serve as accessible biomarkers, while also modulating cell differentiation processes.
  • Trophoblast differentiation is critical for placental formation and function in mammals.

Purpose of the Study:

  • To review the role of miRNAs in placental development.
  • To explore miRNA-mediated regulation of materno-fetal immune dialogue, trophoblast differentiation, and angiogenesis.
  • To highlight the influence of oxygen concentration and imprinted genes on placental miRNA functions.

Main Methods:

  • Literature review of current research on miRNAs in placentation.
  • Analysis of miRNA involvement in key placental processes.
  • Examination of regulatory factors including oxygen and imprinted genes.

Main Results:

  • miRNAs are integral to regulating the complex processes of placentation.
  • Specific miRNA functions are identified in immune modulation, trophoblast fate determination, and vascular development.
  • Oxygen tension and imprinted genes represent significant regulatory layers for placental miRNA activity.

Conclusions:

  • miRNAs are essential mediators of placental development and function.
  • Understanding miRNA roles offers insights into potential biomarkers and therapeutic targets.
  • The interplay of oxygen and imprinted genes with miRNAs shapes placental biology.

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

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...

Cell Migration01:09

Cell Migration

Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.
