Abstract

Insights

The mammalian target of rapamycin (mTOR) signaling pathway is crucial for maintaining glomerular and podocyte function. Dysregulation of mTOR contributes to the development of various glomerular diseases.

Area of Science:

  • Cellular Biology
  • Molecular Biology
  • Nephrology

Background:

  • Mammalian target of rapamycin (mTOR) is a conserved protein kinase regulating vital cellular processes.
  • mTOR signaling is implicated in cancer, diabetes, neurodegenerative disorders, and polycystic kidney disease.
  • The role of mTOR in glomerular homeostasis was previously underexplored.

Purpose of the Study:

  • To review the current understanding of mTOR signaling in podocyte biology.
  • To discuss the implications of mTOR signaling in glomerular diseases.

Main Methods:

  • Literature review of emerging studies on mTOR signaling.
  • Analysis of mTOR's role in podocyte function and glomerular homeostasis.

Main Results:

  • The mTOR signaling pathway plays significant roles in both maintaining and disrupting glomerular and podocyte function.
  • Emerging research highlights these critical functions.

Conclusions:

  • mTOR signaling is integral to podocyte biology.
  • Understanding mTOR pathways is essential for addressing the pathogenesis of glomerular diseases.

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 rapamycin-insensitive companion...
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...
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...
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...
