Abstract

Insights

Jianpi Huayu Decoction (JPHYD) inhibits liver cancer growth by blocking epithelial-mesenchymal transition (EMT). This traditional Chinese medicine increases Smad7 and decreases miR-21-5p, offering a potential new therapeutic strategy for hepatocellular carcinoma.

Area of Science:

  • Oncology
  • Molecular Biology
  • Traditional Chinese Medicine

Background:

  • Hepatocellular carcinoma (HCC) is a major global health concern.
  • Jianpi Huayu Decoction (JPHYD) shows potential in inhibiting HCC growth, but its underlying mechanisms require elucidation.

Purpose of the Study:

  • To investigate the anti-cancer effects and molecular mechanisms of JPHYD on hepatocellular carcinoma cells.
  • To determine JPHYD's impact on epithelial-mesenchymal transition (EMT) in HCC.

Main Methods:

  • In vitro assays (CCK8, EdU, wound-healing, Transwell) using HCC cell lines (HepG2, MHCC97H).
  • Western blot and qRT-PCR to analyze protein and microRNA expression (E-cadherin, Smad7, N-cadherin, Snail, Smad3, Vimentin, Zeb1, miR-21-5p).
  • In vivo xenograft tumor models and imaging in animals.

Main Results:

  • JPHYD significantly inhibited proliferation, migration, and invasion of HCC cells.
  • JPHYD modulated EMT markers by increasing E-cadherin and Smad7, while decreasing N-cadherin, Snail, Vimentin, Smad3, and Zeb1.
  • JPHYD reduced the expression of miR-21-5p, which was found to promote HCC cell migration.

Conclusions:

  • JPHYD exerts anti-cancer effects by inhibiting EMT in hepatocellular carcinoma.
  • The mechanism involves upregulating Smad7 and downregulating miR-21-5p.
  • JPHYD represents a promising therapeutic approach for liver cancer by targeting EMT.

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

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...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

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...

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...
