Abstract

Insights

Ginsenoside Rh2 inhibits triple-negative breast cancer (TNBC) growth by suppressing the IL-6/JAK2/STAT3 pathway. This study reveals key molecular mechanisms for ginsenoside Rh2

Area of Science:

  • Molecular Biology
  • Cancer Research
  • Pharmacology

Background:

  • Triple-negative breast cancer (TNBC) presents significant therapeutic challenges.
  • Ginsenoside Rh2 shows promise in inducing apoptosis in TNBC cells, but its mechanisms are unclear.
  • Understanding ginsenoside Rh2's molecular targets is crucial for its therapeutic application in TNBC.

Purpose of the Study:

  • To elucidate the molecular mechanisms by which ginsenoside Rh2 regulates apoptosis and proliferation in TNBC.
  • To identify key molecular targets and signaling pathways involved in ginsenoside Rh2's anti-TNBC effects.
  • To provide new insights into the therapeutic potential of ginsenoside Rh2 for TNBC treatment.

Main Methods:

  • Network analysis and transcriptome sequencing to identify potential targets.
  • In vivo imaging and immunohistochemistry in a TNBC mouse model.
  • Functional assays, ELISA, Western blot, and qRT-PCR to assess cellular effects and molecular mechanisms.

Main Results:

  • Network analysis identified 47 common targets, with GO enrichment suggesting roles in apoptosis, proliferation, and kinase activity.
  • The JAK/STAT signaling pathway, specifically the IL-6/JAK2/STAT3 axis, was identified as a key mechanism.
  • Ginsenoside Rh2 inhibited tumor growth in vivo and reduced key proteins (IL-6, IL-6R, STAT3, Bcl-2, Bcl-xL) and kinases (AMPK-α1, PKA-Cα) in TNBC.

Conclusions:

  • Ginsenoside Rh2 effectively regulates TNBC proliferation and apoptosis by suppressing the IL-6/JAK2/STAT3 pathway.
  • Findings were validated both in vitro and in vivo, confirming the pathway's central role.
  • This study significantly advances the understanding of ginsenoside Rh2's therapeutic potential against TNBC.

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

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...

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...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

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...
