Insights

Actein, derived from Cimicifuga foetida, ameliorates liver injury and progression towards cancer in mice. This triterpene glycoside suppressed key cancer markers, suggesting potential as a therapeutic agent for early liver cancer.

Area of Science:

  • Pharmacology
  • Hepatology
  • Oncology

Background:

  • Actein, a triterpene glycoside from Cimicifuga foetida, inhibits breast cancer cell proliferation.
  • The role of actein in preventing liver injury and early liver cancer remains largely unknown.

Purpose of the Study:

  • To investigate the therapeutic potential of actein in a mouse model of early liver cancer induced by diethylnitrosamine (DEN).

Main Methods:

  • Liver cancer was induced in mice using DEN, followed by treatment with varying concentrations of actein.
  • Histological analysis and assessment of proliferation and cancer stem cell markers (Cyclin Ds, p53, CD133) were performed.
  • Expression levels of hypoxia-inducible factor-1α (Hif-1α) and vascular endothelial growth factor receptor 1 (VEGFR1) were evaluated.

Main Results:

  • DEN-induced liver injury, characterized by steatohepatitis, fibrosis, and inflammation, was significantly ameliorated by actein treatment.
  • Actein reversed DEN-induced hepatobiliary cysts and suppressed the expression of proliferation markers (Cyclin Ds, p53) and cancer stem cell markers (CD133).
  • Actein administration reduced the upregulation of Hif-1α and VEGFR1 in DEN-treated liver tissues.

Conclusions:

  • Actein demonstrates protective effects against DEN-induced liver injury and cancer progression in mice.
  • Actein exhibits inhibitory effects on key molecular pathways involved in liver cancer development.
  • Actein represents a promising therapeutic candidate for future liver cancer treatment strategies.

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Cancer Stem Cells and Tumor Maintenance

Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Drugs that Stabilize Microtubules

Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...
