Abstract

Insights

Gamma-tocotrienol (γ-T3) may treat gastric cancer by inhibiting the notch signaling pathway. This study explored γ-T3

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Gastric cancer is a leading cause of cancer mortality globally.
  • There is a critical need for novel therapeutic targets and drugs for gastric cancer treatment.
  • Tocotrienols (T3) exhibit promising anticancer properties in various cancer cell lines.

Purpose of the Study:

  • To investigate the underlying mechanisms of gamma-tocotrienol (γ-T3) in gastric cancer therapy.
  • To build upon previous findings that γ-T3 induces apoptosis in gastric cancer cells.
  • To identify specific molecular pathways affected by γ-T3 treatment.

Main Methods:

  • Gastric cancer cells were treated with γ-T3.
  • RNA sequencing (RNA-seq) was performed on treated and untreated gastric cancer cells.
  • Analysis of mRNA, ncRNA, and signaling pathway alterations was conducted.

Main Results:

  • γ-T3 treatment inhibited mitochondrial complexes and oxidative phosphorylation in gastric cancer cells.
  • Significant alterations in mRNA and ncRNA expression were observed post γ-T3 treatment.
  • The human papillomavirus (HPV) infection and notch signaling pathways were significantly altered, with down-regulation of Notch1 and Notch2 genes.

Conclusions:

  • γ-T3 shows potential as a therapeutic agent for gastric cancer by inhibiting the notch signaling pathway.
  • This research provides a foundation for developing new clinical treatments for gastric cancer.
  • Targeting the notch signaling pathway with γ-T3 represents a novel therapeutic strategy.

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...

Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

mTOR Signaling and Cancer Progression03:03

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.
The mTOR pathway or the...

TGF - β Signaling Pathway01:16

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...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

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...
