Insights

MicroRNAs (miRNAs) regulate gene expression by suppressing or enhancing transcription. Understanding these dual roles is crucial for developing biomarkers and therapies for metabolic diseases and cancer.

Area of Science:

  • Molecular Biology
  • Genetics
  • Biochemistry

Background:

  • MicroRNAs (miRNAs) are key regulators of gene expression, primarily known for inhibiting mRNA translation and promoting degradation.
  • Recent findings reveal that miRNAs can also act as positive regulators, enhancing gene transcription.

Purpose of the Study:

  • To review the regulatory mechanisms and functional roles of miRNAs in metabolic diseases and cancer.
  • To highlight recent advances in understanding miRNAs' unconventional gene-enhancing functions.
  • To underscore the clinical implications of miRNA research for disease treatment and risk assessment.

Main Methods:

  • Literature review of accumulated data over several decades.
  • Focus on mechanisms of gene expression regulation by miRNAs.
  • Analysis of miRNA roles in metabolic diseases (obesity, type 2 diabetes) and cancer.

Main Results:

  • miRNAs exhibit a Yin-Yang functional feature, acting as both suppressors and enhancers of gene expression.
  • Unconventional roles of miRNAs in promoting gene transcription are increasingly recognized.
  • miRNAs hold significant potential as biomarkers and therapeutic targets.

Conclusions:

  • A comprehensive understanding of miRNA regulatory mechanisms, including their enhancing functions, is vital.
  • Elucidating miRNA's dual roles can lead to significant clinical advancements in treating obesity, type 2 diabetes, and cancer.
  • Further research into miRNA mechanisms could unlock novel diagnostic and therapeutic strategies.

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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

Insulin: The Receptor and Signaling Pathways01:28

Insulin: The Receptor and Signaling Pathways

Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
