Insights

MicroRNAs (miRNAs) regulate the tumor suppressor Phosphatase and tensin homolog (PTEN) gene. Understanding these miRNA-PTEN interactions is crucial for cancer prevention and treatment, and managing other diseases.

Area of Science:

  • Molecular Biology
  • Oncology
  • Genetics

Background:

  • The Phosphatase and tensin homolog (PTEN) gene is a critical tumor suppressor.
  • PTEN negatively regulates the PI3K/AKT signaling pathway, impacting cell growth and survival.
  • Dysregulation of PTEN is implicated in various malignancies and non-malignant disorders.

Purpose of the Study:

  • To review the regulatory roles of microRNAs (miRNAs) in PTEN expression and activity.
  • To highlight the significance of understanding miRNA-PTEN interactions in cancer and other diseases.

Main Methods:

  • Literature review of studies investigating miRNA-PTEN interactions.
  • Analysis of the functional consequences of these interactions in different biological contexts.

Main Results:

  • Numerous miRNAs have been identified to directly interact with and inhibit PTEN expression.
  • Suppression of PTEN by miRNAs can affect cancer cell response to chemotherapy.
  • miRNA-PTEN interactions are also relevant in non-malignant conditions like myocardial infarction and stroke.

Conclusions:

  • miRNAs are significant regulators of PTEN, influencing both its expression and activity.
  • Targeting miRNA-PTEN interactions may offer therapeutic strategies for cancer and other diseases.
  • Further research into these interactions is essential for clinical applications.

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...

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 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 JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

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...

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...
