Canonical Wnt Signaling Pathway02:54

Canonical Wnt Signaling Pathway

8.7K
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...

Non-Canonical Wnt Signaling Pathways

7.3K
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...

Targeted Cancer Therapies

7.5K
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...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.1K
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,...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

3.8K
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...

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Signaling

Background:

  • WNT signaling plays a role in osteosarcoma proliferation, but its exact function (pro- or anti-tumorigenic) is debated.
  • WNT pathway modulators are being explored as potential therapeutics for osteosarcoma.
  • Specific WNT ligands, such as WNT5B (β-catenin-independent) and WNT10B (β-catenin-dependent), are expressed in osteosarcomas.

Purpose of the Study:

  • To investigate the dual role of WNT signaling in osteosarcoma.
  • To compare WNT-targeting therapeutics (activators and inhibitors).
  • To determine if WNT ligand and pathway specificity influences therapeutic outcomes.

Main Methods:

  • Analysis of WNT5B and WNT10B expression in osteosarcoma subtypes.
  • Comparison of WNT pathway activators and inhibitors as therapeutic strategies.
  • Evaluation of the impact of WNT ligand and pathway activation on osteosarcoma progression.

Main Results:

  • WNT5B and WNT10B are expressed in distinct osteosarcoma tumors.
  • These ligands regulate different histological subtypes of osteosarcoma.
  • The efficacy of WNT modulators may be dependent on the specific WNT ligand and activated pathway.

Conclusions:

  • WNT signaling's role in osteosarcoma is complex and ligand-dependent.
  • Therapeutic strategies targeting WNT signaling must consider the specific WNT ligand and pathway involved.
  • Personalized therapeutic approaches based on WNT pathway activation are crucial for osteosarcoma treatment.
