Insights

The Hippo pathway is crucial for organ size and preventing cancer. Understanding its upstream regulators and protein interactions offers new therapeutic targets for diseases, especially cancer.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Oncology

Background:

  • The Hippo pathway is a critical regulator of organ size and a tumor suppressor.
  • Recent research has identified numerous upstream factors influencing the Hippo pathway.
  • Dysregulation of this pathway contributes to uncontrolled cell proliferation and cancer development.

Purpose of the Study:

  • To review the current understanding of the Hippo pathway.
  • To focus on upstream regulators and protein-protein interactions as therapeutic targets.
  • To explore pharmacological interventions for Hippo pathway-related diseases, particularly cancer.

Main Methods:

  • Literature review of recent advancements in Hippo pathway research.
  • Analysis of upstream signaling mechanisms and protein interactions.
  • Discussion of potential therapeutic strategies targeting the Hippo pathway.

Main Results:

  • Key components and upstream regulators of the Hippo pathway have been identified.

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...

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...
Regulation of Angiogenesis and Blood Supply01:24

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 hydroxylase and factor...
