Insights

Armadillo repeat protein C10 (ARMC10) promotes glioblastoma (GBM) growth by activating the Notch pathway and fatty acid metabolism. Reducing ARMC10 levels inhibits GBM progression and improves patient prognosis.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Glioblastoma (GBM) is an aggressive brain tumor with limited treatment options.
  • The role of armadillo repeat protein C10 (ARMC10) in GBM pathogenesis remains largely unexplored.

Purpose of the Study:

  • To investigate the biological functions and underlying mechanisms of ARMC10 in glioblastoma.
  • To determine the prognostic significance of ARMC10 expression in GBM patients.

Main Methods:

  • Bioinformatics analysis of ARMC10 expression and its correlation with GBM.
  • In vitro functional assays (proliferation, invasion, migration, lipid levels) using ARMC10 knockdown in GBM cells.
  • In vivo studies using mouse xenograft models to assess ARMC10's effect on tumor growth.
  • Gene Set Enrichment Analysis (GSEA) to identify associated molecular pathways.

Main Results:

  • ARMC10 is upregulated in GBM, and high expression correlates with a poorer prognosis.
  • ARMC10 knockdown significantly inhibits GBM cell proliferation, invasion, and migration.
  • ARMC10 promotes GBM progression via positive association with the Notch pathway and fatty acid metabolism.
  • ARMC10 knockdown reduces lipid levels and inhibits key proteins in fatty acid metabolism and Notch signaling.
  • Overexpression of Notch receptor 1 (Notch1) reversed the inhibitory effects of ARMC10 knockdown.

Conclusions:

  • ARMC10 plays a crucial role in promoting glioblastoma malignant progression.
  • Targeting ARMC10 and its associated Notch pathway and fatty acid metabolism may offer a therapeutic strategy for GBM.

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...

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...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

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.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

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...
