Insights

Targeting transforming growth factor beta (TGFβ) in pancreatic cancer is complex. Inhibiting stromal TGFβ receptor 2 (Tgfβr2) effectively reduced pancreatic ductal adenocarcinoma metastasis in preclinical models.

Area of Science:

  • Oncology
  • Cancer Biology
  • Molecular Biology

Background:

  • Pancreatic ductal adenocarcinoma (PDA) progression is influenced by transforming growth factor beta (TGFβ).
  • Therapeutic targeting of the TGFβ pathway in PDA remains a significant challenge due to its complex role.

Purpose of the Study:

  • To investigate the therapeutic potential of targeting stromal TGFβ signaling in PDA.
  • To evaluate the impact of inhibiting TGFβ receptor 2 (Tgfβr2) on epithelial plasticity and metastasis in PDA models.

Main Methods:

  • Utilized antibody-mediated inhibition of stromal Tgfβr2 in preclinical xenograft models of PDA.
  • Assessed the effects on epithelial plasticity, a key driver of cancer progression and metastasis.

Main Results:

  • Antibody-mediated inhibition of stromal Tgfβr2 prevented or reversed epithelial plasticity.
  • This inhibition led to a significant reduction in PDA metastasis in the studied xenograft models.

Conclusions:

  • Targeting stromal Tgfβr2 represents a promising therapeutic strategy for pancreatic ductal adenocarcinoma.
  • Inhibition of this pathway effectively mitigates PDA metastasis by controlling epithelial plasticity.

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...

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 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...
