Insights

Pediatric bone sarcomas like osteosarcoma and Ewing sarcoma remain deadly, with nearly 40% of patients succumbing to the disease. Emerging research highlights the Hippo/YAP signaling pathway

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Research

Background:

  • Osteosarcoma and Ewing sarcoma are the most common pediatric bone cancers.
  • Despite advances, nearly 40% of patients with these sarcomas do not survive due to metastasis or chemotherapy resistance.
  • The Hippo/YAP signaling pathway has gained attention for its role in cancer progression.

Purpose of the Study:

  • To review the current understanding of the Hippo signaling pathway's involvement in cancer.
  • To specifically examine the role of the Hippo signaling pathway in the progression of pediatric bone sarcomas.

Main Methods:

  • Literature review of studies on the Hippo signaling pathway and pediatric bone sarcomas.
  • Analysis of the pathway's functions in tumor growth, angiogenesis, epithelial to mesenchymal transition, and metastasis.

Main Results:

  • The Hippo signaling pathway influences multiple stages of tumor progression.
  • This pathway is implicated in primary tumor growth, the formation of new blood vessels (angiogenesis), and the spread of cancer cells (metastatic dissemination).

Conclusions:

  • The Hippo signaling pathway is a critical player in the progression of pediatric bone sarcomas.
  • Understanding this pathway may reveal new therapeutic targets for osteosarcoma and Ewing sarcoma.

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...

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

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.

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...

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 JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
