Insights

Mutations in the PI3K-AKT-mTOR pathway cause rare genetic disorders with tissue overgrowth. Identifying these gene mutations aids diagnosis, counseling, and developing new treatments for these intractable conditions.

Area of Science:

  • Molecular Biology
  • Genetics
  • Dermatology

Background:

  • Cellular homeostasis relies on signaling pathways like PI3K-AKT-mTOR.
  • This pathway regulates cell survival, differentiation, and proliferation during development.

Purpose of the Study:

  • To explore the role of PI3K-AKT-mTOR pathway mutations in heritable skin disorders with tissue overgrowth.
  • To establish a basis for novel classifications and treatments for these conditions.

Main Methods:

  • Analysis of genetic mutations in patients with specific skin overgrowth syndromes.
  • Review of existing literature on PI3K-AKT-mTOR pathway signaling and related diseases.

Main Results:

  • Heritable diseases with tissue overgrowth are linked to mutations in the PI3K-AKT-mTOR pathway and interacting pathways.
  • Phenotypic manifestations often overlap, suggesting a spectrum of related disorders.

Conclusions:

  • Identifying specific gene mutations is crucial for accurate diagnostics and genetic counseling.
  • Understanding these mutations provides a rationale for developing targeted therapies for intractable overgrowth disorders.

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...

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 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...

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.
Ras is a...

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
