Abstract

Insights

Quercetin effectively suppresses pancreatic cancer stem-like cells by targeting beta-catenin. Combining quercetin with gemcitabine offers a promising strategy to overcome drug resistance and improve patient outcomes.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Pancreatic cancer is characterized by drug-resistant cancer stem-like cells (CSCs).
  • Understanding CSC properties and drug resistance mechanisms is crucial for effective treatment.

Purpose of the Study:

  • To investigate the interaction between quercetin and pancreatic cancer stem-like cells.
  • To elucidate the mechanism of quercetin-mediated suppression in pancreatic CSCs.
  • To evaluate the combined effect of quercetin and gemcitabine.

Main Methods:

  • Generated pancreatic cancer stem-like cells using sphere formation culture.
  • Performed comparative analysis of parent cells and CSCs regarding CSC properties and drug resistance.
  • Assessed the effects of quercetin on proliferation, invasion, self-renewal, CSC markers, and beta-catenin expression.
  • Evaluated the combination therapy of quercetin and gemcitabine in vitro.

Main Results:

  • Pancreatic CSCs exhibited enhanced gemcitabine resistance and CSC properties compared to parent cells.
  • Quercetin suppressed CSC proliferation, invasion, self-renewal, and CSC marker expression.
  • Quercetin altered beta-catenin expression in pancreatic CSCs.
  • Combination of quercetin and gemcitabine reduced tumor growth and drug resistance.

Conclusions:

  • Beta-catenin is vital for pancreatic cancer maintenance and progression.
  • Targeting beta-catenin with quercetin and gemcitabine presents a potential therapeutic strategy.
  • This combination therapy may improve prognosis for pancreatic cancer patients.

Catenins01:23

Catenins

Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.
Catenins in Cell Junctions
Catenins bind to cell adhesion molecules such as cadherins and link them to different cytoskeletal proteins depending on the type of cell junction. At the...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

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...

Canonical Wnt Signaling Pathway02:54

Canonical Wnt Signaling Pathway

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...

Renewal of Intestinal Stem Cells01:23

Renewal of Intestinal Stem Cells

The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...
