Insights

The Hippo signaling pathway regulates organ size and is implicated in lung cancer. Non-coding RNAs and anti-cancer agents modulate this pathway, offering potential therapeutic strategies for lung cancer.

Area of Science:

  • Molecular Biology
  • Oncology
  • Genetics

Background:

  • The Hippo pathway, initially identified in Drosophila, regulates organ size and is crucial for homeostasis and preventing tumorigenesis.
  • Key components include tumor suppressors like hippo (hpo) and warts (wts), and oncogenes like yorkie (yki).
  • Emerging evidence highlights the Hippo pathway's significant role in lung carcinogenesis.

Purpose of the Study:

  • To review the involvement of the Hippo signaling pathway in lung cancer progression.
  • To explore the impact of non-coding RNAs on Hippo pathway activity in lung cancer.
  • To summarize the effects of various anti-cancer agents on the Hippo pathway in the context of lung cancer.

Main Methods:

  • Literature review of recent studies on Hippo signaling in lung cancer.
  • Analysis of research investigating non-coding RNAs (miRNAs, PVT1, SFTA1P, NSCLCAT1, circ_0067741) and their interaction with the Hippo pathway.
  • Compilation of data on anti-cancer agents (gallic acid, icotinib hydrochloride, curcumin, etc.) and their mechanisms involving Hippo pathway modulation.

Main Results:

  • The Hippo pathway influences lung cancer through various mechanisms, including interactions with microRNAs (miRNAs).
  • Several non-coding RNAs are implicated in lung carcinogenesis by affecting the Hippo pathway.
  • Numerous anti-cancer agents exert their effects in lung cancer by modulating the Hippo signaling pathway.

Conclusions:

  • The Hippo signaling pathway is a critical player in lung cancer development and progression.
  • Non-coding RNAs represent a significant regulatory layer impacting the Hippo pathway in lung cancer.
  • Targeting the Hippo pathway with specific anti-cancer agents holds promise for lung cancer therapy.

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...

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...

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.
The mTOR pathway or the...

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...

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
