Insights

Transmembrane protein with EGF and two follistatin motifs 2 (TMEFF2) exhibits dual roles in prostate cancer. Different TMEFF2 forms distinctly impact Akt and ERK pathways, influencing cell proliferation or tumor suppression.

Area of Science:

  • Molecular biology
  • Cancer research
  • Cell signaling

Background:

  • Transmembrane protein with EGF and two follistatin motifs 2 (TMEFF2) is highly expressed in the prostate.
  • TMEFF2 presents a dual role in prostate cancer, acting as both an oncogene and a tumor suppressor.
  • Metalloproteinase-dependent shedding generates a soluble TMEFF2 ectodomain with growth-promoting functions.

Purpose of the Study:

  • To investigate the role of full-length TMEFF2 in prostate cancer cell signaling.
  • To examine how different TMEFF2 forms influence ERK and Akt activation pathways.
  • To elucidate the molecular mechanisms underlying TMEFF2's oncogenic and tumor-suppressive functions.

Main Methods:

  • Utilized prostate cancer cell lines for experimental analysis.
  • Investigated the activation of ERK and Akt signaling pathways.
  • Compared the effects of different TMEFF2 forms on cellular responses.

Main Results:

  • Different forms of TMEFF2 differentially regulate Akt and ERK activation.
  • Observed distinct effects of TMEFF2 on key signaling pathways implicated in cancer progression.
  • Results suggest a link between TMEFF2's impact on these pathways and its dual role in proliferation versus tumor suppression.

Conclusions:

  • The distinct effects of TMEFF2 forms on Akt and ERK pathways contribute to its complex role in prostate cancer.
  • Understanding these molecular mechanisms is crucial for deciphering TMEFF2's oncogenic or tumor-suppressive functions.
  • Further research into TMEFF2 signaling can inform novel therapeutic strategies for prostate cancer.

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...
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...
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.

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

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 are of three kinds RI, RII, and RIII. The RI...
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...
