Insights

Glioblastoma treatment remains poor due to resistant residual tumors. Understanding molecular networks offers new therapeutic targets for refractory gliomas, improving patient outcomes.

Area of Science:

  • Neuro-oncology
  • Molecular Biology
  • Genetics

Background:

  • Glioblastoma (GBM) treatment outcomes remain poor despite advances in surgery and adjuvant therapies.
  • Limited tumor resection and residual tumor resistance to radiation and chemotherapy contribute to poor prognosis.
  • Novel therapeutic strategies are urgently needed to overcome treatment resistance in gliomas.

Purpose of the Study:

  • To review current understanding of molecular networks governing glioma biology.
  • To focus on how intracellular signaling molecules in gliomas contribute to therapeutic resistance.
  • To identify potential novel therapeutic targets against refractory gliomas.

Main Methods:

  • Review of recent large cohort studies on genetic alterations in glioblastoma.
  • Analysis of evidence on molecular networks and intracellular signaling pathways in gliomas.
  • Focus on the association between signaling molecules and resistance to current therapies.

Main Results:

  • Genetic information and intracellular molecular signaling are networked in gliomas.
  • Specific molecules and signaling pathways play essential roles in resistance to radiation and chemotherapy.
  • These networks offer insights into the mechanisms of refractoriness in gliomas.

Conclusions:

  • Understanding molecular networks is crucial for developing effective glioma treatments.
  • Targeting specific intracellular signaling molecules may overcome resistance to current therapies.
  • This knowledge can lead to novel therapeutic strategies for refractory glioblastoma.

Signal Transduction: Overview01:26

Signal Transduction: Overview

Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
Typically, signal transduction involves three...

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...

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...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

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...
