Abstract

Insights

Itraconazole, an anti-fungal drug, effectively inhibits endometrial cancer (EC) cell growth and migration. This study suggests itraconazole may suppress EC progression by targeting the Hedgehog pathway.

Area of Science:

  • Oncology
  • Pharmacology

Background:

  • Limited therapeutic options exist for endometrial cancer (EC).
  • Itraconazole, an anti-fungal agent, inhibits the Hedgehog pathway and shows efficacy in various cancers.
  • Its efficacy in EC treatment remains unexplored.

Purpose of the Study:

  • To evaluate the efficacy of itraconazole in treating endometrial cancer.
  • To investigate the role of Hedgehog signaling in EC progression.

Main Methods:

  • Immunohistochemistry performed on EC tumor samples, including serous endometrial intraepithelial carcinoma (SEIC).
  • In vitro evaluation of itraconazole's effect on EC cell line proliferation and migration.

Main Results:

  • Sonic Hedgehog and GLI1 expression confirmed in SEIC and endometrioid adenocarcinoma.
  • Itraconazole significantly inhibited EC tumor cell growth in a dose- and time-dependent manner.
  • Itraconazole inhibited the migration of HEC-1A cells.

Conclusions:

  • Hedgehog signaling is implicated in EC carcinogenesis and malignant progression.
  • Physiological doses of itraconazole show potential in suppressing EC progression.

Hedgehog Signaling Pathway02:33

Hedgehog Signaling Pathway

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

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.

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...
