Insights

The Hippo pathway controls organ size and restrains cancer. Understanding its regulators, like YAP, offers new therapeutic targets for effective cancer drug development.

Area of Science:

  • Cell Biology
  • Oncology
  • Molecular Biology

Background:

  • The Hippo pathway, conserved from Drosophila to mammals, is crucial for organ size control.
  • This pathway plays a significant role in restraining cancer development.
  • Dysregulation of the Hippo pathway is implicated in various solid malignancies.

Purpose of the Study:

  • To discuss newly identified and key regulators of the Hippo pathway.
  • To explore the connection of these regulators with core Hippo components (MST1/2, LATS1/2, SAV1, MOB1) and the downstream effector YAP.
  • To highlight the role of these regulators in cancer development and progression.

Main Methods:

  • Review of recent scientific literature on Hippo pathway regulators.
  • Analysis of molecular mechanisms connecting regulators to core Hippo pathway components.
  • Discussion of pathway crosstalk and extracellular stimuli influencing Hippo signaling.

Main Results:

  • Identification of novel molecules modulating Hippo pathway signaling.
  • Elucidation of connections between regulators and core Hippo pathway components (MST1/2, LATS1/2, SAV1, MOB1) and YAP.
  • Demonstration of the pathway's role in cancer development and progression.

Conclusions:

  • Understanding mammalian Hippo pathway regulation is key for cancer therapy.
  • New insights may enable selection of appropriate oncogenic targets.
  • Effective drug design for cancer treatment can be advanced through this knowledge.

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.

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...

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 rapamycin-insensitive companion...
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...
