Summary

This summary is machine-generated.

The transforming growth factor-β (TGF-β)/small mothers against decapentaplegic 3 (Smad3) pathway drives pancreatic cancer progression and stem cell traits. Inhibiting this pathway suppressed tumor growth, migration, and stemness, offering therapeutic potential.

Area Of Science

  • Oncology
  • Molecular Biology
  • Cancer Stem Cell Research

Background

  • Pancreatic cancer (PC) is a lethal malignancy driven by cancer stem cells (CSCs).
  • The transforming growth factor-β (TGF-β)/small mothers against decapentaplegic 3 (Smad3) signaling pathway's role in PC is not fully understood.
  • Investigating this pathway is crucial for understanding PC progression and identifying therapeutic targets.

Purpose Of The Study

  • To elucidate the role of the TGF-β/Smad3 pathway in pancreatic cancer development.
  • To determine the pathway's impact on cancer stem cell (CSC) properties in PC.
  • To evaluate the therapeutic potential of targeting the TGF-β/Smad3 pathway in PC.

Main Methods

  • Bioinformatic analysis of TGF-β and Smad3 expression in PC tissues using GEPIA and XIANTAO.
  • In vitro study using PANC-1 cells with TGF-β inhibition and Smad3 overexpression.
  • Assessment of cell proliferation, migration, apoptosis, and CSC sphere formation using MTT, wound healing, flow cytometry, and sphere formation assays.

Main Results

  • TGF-β and Smad3 were significantly upregulated in PC tissues, correlating with poor prognosis.
  • Inhibition of TGF-β reduced PC cell proliferation, migration, and sphere formation while enhancing apoptosis.
  • Smad3 overexpression promoted PC cell growth and enhanced CSC characteristics.

Conclusions

  • The TGF-β/Smad3 signaling pathway is activated in pancreatic cancer and promotes tumor growth, metastasis, and CSC-like traits.
  • Targeting the TGF-β/Smad3 pathway presents a promising therapeutic strategy for improving PC outcomes.
  • Further research into this pathway could lead to novel treatments for pancreatic cancer.

TGF - β Signaling Pathway 01:16

7.6K

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 03:03

3.9K

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...

Role Of Notch Signalling In Intestinal Stem Cell Renewal 01:12

2.2K

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

The Tumor Microenvironment 02:17

6.8K

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Mesenchymal Stem Cells 01:19

5.0K

Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

Interactions Between Signaling Pathways 01:19

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...
