Abstract

Insights

The Hippo signaling pathway and its downstream target Yes-associated protein (YAP) are crucial in cell growth and organ size regulation. Dysregulation of this pathway drives liver carcinogenesis, suggesting YAP as a therapeutic target for cancer treatment.

Area of Science:

  • Oncology
  • Molecular Biology
  • Signal Transduction

Background:

  • The Hippo signaling pathway is a critical regulator of cell growth and organ size, functioning as a tumor suppressor.
  • Yes-associated protein (YAP) is a key downstream effector of the Hippo pathway, acting as a transcription co-activator.
  • Aberrant Hippo signaling and YAP activity are increasingly linked to oncogenesis, particularly in solid tumors.

Purpose of the Study:

  • To review the emerging roles of YAP and Hippo signaling in cancer development.
  • To explore potential therapeutic strategies targeting the Hippo pathway and its components for cancer treatment.

Main Methods:

  • Review of recent scientific literature on the Hippo signaling pathway, YAP, and their roles in oncogenesis.
  • Discussion of potential therapeutic targets within the Hippo pathway and associated signaling networks.

Main Results:

  • The Hippo pathway and YAP are implicated as significant drivers in various cancers.
  • Inactivation of Hippo signaling leads to YAP-mediated gene activation, promoting cell proliferation and organ overgrowth.
  • YAP is identified as a key oncogenic driver in liver carcinogenesis.

Conclusions:

  • Deregulation of the Hippo pathway and YAP activity contributes to tumor formation and malignancy.
  • Targeting YAP and its downstream signaling pathways presents a promising clinical strategy for cancer therapy.

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...

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...

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...
