Abstract

Insights

Diosgenin, derived from fenugreek, inhibits cancer cell growth by down-regulating human telomerase reverse transcriptase (hTERT) gene expression, a key target for cancer therapy.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Pharmacology

Background:

  • Diosgenin, a natural compound from fenugreek, exhibits anticancer properties.
  • Telomerase is reactivated in cancer cells, making it a therapeutic target.
  • Human telomerase reverse transcriptase (hTERT) is crucial for telomerase activity.

Purpose of the Study:

  • To investigate diosgenin's inhibitory effect on hTERT gene expression.
  • To assess diosgenin's impact on telomerase activity in cancer cells.

Main Methods:

  • Cytotoxicity was evaluated using MTT assays.
  • hTERT gene expression was analyzed via qRT-PCR.
  • A549 lung cancer cell line was used for experiments.

Main Results:

  • Diosgenin demonstrated dose-dependent cytotoxicity with IC50 values ranging from 43-47μM.
  • Diosgenin treatment led to the down-regulation of hTERT gene expression.
  • Inhibition of hTERT expression suggests a mechanism for telomerase activity suppression.

Conclusions:

  • Diosgenin effectively inhibits telomerase activity in A549 lung cancer cells.
  • The mechanism involves the down-regulation of hTERT gene expression.
  • Diosgenin shows potential as a therapeutic agent targeting telomerase in lung cancer.

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
