Insights

Mammalian target of rapamycin (mTOR) regulates cell metabolism and proliferation. mTORC1 inhibitors show promise for treating tuberous sclerosis complex (TSC), a disease caused by mTORC1 overactivation.

Area of Science:

  • Cellular biology
  • Biochemistry
  • Molecular medicine

Background:

  • Mammalian target of rapamycin (mTOR) is a key kinase regulating cellular processes.
  • mTOR exists in two complexes, mTORC1 and mTORC2, with distinct functions.
  • mTORC1 dysfunction is linked to various diseases, including cancer and neurological disorders.

Purpose of the Study:

  • To summarize current knowledge on mTOR signaling.
  • To review the efficacy of mTORC1 inhibitors in treating tuberous sclerosis complex (TSC).

Main Methods:

  • Literature review of mTOR signaling pathways.
  • Analysis of studies on mTORC1 inhibitors and their therapeutic effects.

Main Results:

  • mTORC1 is a central regulator of metabolism, proliferation, and autophagy.
  • mTORC1 hyperactivity, often due to TSC1/TSC2 mutations, causes TSC.
  • mTORC1 inhibitors, like rapamycin, effectively alleviate TSC symptoms.

Conclusions:

  • mTORC1 plays a critical role in cellular functions and disease pathogenesis.
  • Targeting mTORC1 with inhibitors offers a viable therapeutic strategy for TSC.

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.

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...

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...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
