mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.0K
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...

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

6.9K
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...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

8.2K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

4.4K
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...

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

7.3K
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

3.0K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Summary

Malignant melanoma cells undergo epithelial-mesenchymal transition (EMT), driven by mutations and environmental factors. Bone morphogenic proteins (BMPs) are key regulators of this process, offering potential therapeutic targets for melanoma.

Area of Science:

  • Oncology
  • Cell Biology
  • Molecular Biology

Background:

  • Malignant melanoma is a deadly skin cancer with poor survival rates for metastatic cases.
  • Melanoma's high mortality is linked to its cells' phenotypic plasticity and rapid metastasis.
  • Current therapies show limited success against advanced melanoma, highlighting the need for novel strategies.

Purpose of the Study:

  • To explore the role of epithelial-mesenchymal transition (EMT) in melanoma progression.
  • To investigate the involvement of signaling pathways, particularly bone morphogenic proteins (BMPs), in melanoma cell plasticity and metastasis.
  • To identify potential therapeutic targets for controlling melanoma EMT.

Main Methods:

  • Phenotypic and molecular analyses of developing melanoma tumors.
  • Review of recent reports on signaling pathways (TGF-β, BMPs) and their role in EMT.
  • Examination of the impact of mutations (BRAF, N-RAS, MEK1/2) and environmental stimuli on melanoma progression.

Main Results:

  • Epithelial-mesenchymal transition (EMT) drives the shift from mature melanocytes to invasive melanoma tumor cells.
  • Mutations in key signaling pathways and microenvironmental factors promote EMT.
  • Bone morphogenic proteins (BMPs) are critical regulators of melanoma cell differentiation, proliferation, invasiveness, and metastasis, influencing transcription and epigenetics.

Conclusions:

  • Understanding BMPs' role in regulating melanoma EMT is crucial for developing new therapeutic strategies.
  • Targeting BMP signaling pathways may offer a novel approach to control melanoma cell plasticity and improve patient outcomes.
  • Further research into BMPs could lead to significant clinical benefits for melanoma patients.
