Abstract

Insights

Sesamin effectively inhibits the Wnt/β-catenin pathway in ovarian cancer cells by downregulating key oncogenic regulators. This natural compound shows promise as a potential therapeutic agent for ovarian cancer treatment.

Area of Science:

  • Molecular biology
  • Cancer research
  • Pharmacology

Background:

  • The Wnt/β-catenin signaling pathway plays a critical role in ovarian cancer development and progression.
  • Identifying novel therapeutic agents targeting this pathway is crucial for effective ovarian cancer treatment.

Purpose of the Study:

  • To investigate the molecular mechanisms by which sesamin modulates the Wnt/β-catenin signaling pathway in ovarian cancer cells.
  • To assess the potential of sesamin as a multi-target therapeutic agent for ovarian cancer.

Main Methods:

  • Molecular docking simulations were employed to predict sesamin's binding affinity to key Wnt/β-catenin pathway proteins (Wnt, β-catenin, GSK3β, TGF-β).
  • Quantitative PCR (qPCR) was used to measure the gene expression levels of Wnt, β-catenin, GSK3β, and TGF-β in sesamin-treated ovarian cancer cells.

Main Results:

  • Molecular docking revealed strong binding interactions between sesamin and Wnt, with a binding energy of -9.19 kcal/mol.
  • Sesamin treatment significantly downregulated the expression of Wnt (50%), TGF-β (40%), GSK3β (25%), and β-catenin transcripts in ovarian cancer cells compared to controls (p < 0.001).

Conclusions:

  • Sesamin demonstrates potent inhibitory effects on multiple oncogenic regulators within the Wnt/β-catenin pathway.
  • These findings suggest sesamin as a promising natural therapeutic candidate for ovarian cancer, potentially useful as an adjuvant therapy to enhance treatment efficacy and limit tumor progression.

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 results in tumor...
Non-Canonical Wnt Signaling Pathways01:41

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

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.

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 adherens...
Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
