Insights

The Hippo pathway regulates organ size and cell growth via YAP and TAZ. Targeting this pathway offers potential for regenerative medicine and cancer therapy by controlling YAP/TAZ activity.

Area of Science:

  • Cell Biology
  • Developmental Biology
  • Molecular Oncology

Background:

  • The Hippo signaling pathway is crucial for organ size control, tumor suppression, and stem cell renewal.
  • YES-associated protein (YAP) and transcriptional co-activator with PDZ-binding motif (TAZ) are key downstream effectors negatively regulated by Hippo signaling.
  • YAP and TAZ activate growth-promoting genes by interacting with transcription factors like TEADs.

Purpose of the Study:

  • To review the regulatory mechanisms of the Hippo signaling pathway.
  • To elucidate the role of the Hippo pathway in tissue repair and cancer.
  • To analyze therapeutic strategies targeting the Hippo pathway, YAP, and TAZ for regenerative medicine and oncology.

Main Methods:

  • Literature review of Hippo pathway mechanisms.
  • Analysis of YAP/TAZ roles in regeneration and cancer.
  • Evaluation of therapeutic targeting strategies.

Main Results:

  • The Hippo pathway, through YAP/TAZ, promotes organ regeneration but can drive cancer when dysregulated.
  • Aberrant YAP/TAZ activation is linked to tumor development.
  • Pharmacological inhibition of YAP/TAZ is a potential cancer treatment strategy.

Conclusions:

  • Understanding Hippo pathway regulation is key for therapeutic interventions.
  • Targeting YAP and TAZ offers dual potential in regenerative medicine and cancer therapy.
  • Further research into Hippo pathway modulators is warranted for clinical applications.

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...

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.

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...

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...
