Abstract

Insights

Triptolide (TL) induces apoptosis in human pancreatic cancer cells by increasing caspase-3 and bax gene expression. This finding offers potential therapeutic strategies for pancreatic cancer treatment.

Area of Science:

  • Molecular biology
  • Cancer research
  • Pharmacology

Background:

  • Pancreatic cancer remains a significant health challenge with limited effective treatments.
  • Understanding the molecular mechanisms of cell death is crucial for developing novel therapeutic agents.

Purpose of the Study:

  • To investigate the induction of apoptosis in human pancreatic cancer cells by Triptolide (TL).
  • To explore the relationship between TL-induced apoptosis and the expression of key apoptosis-related genes: caspase-3, bcl-2, and bax.

Main Methods:

  • Human pancreatic cancer cell line SW1990 was utilized.
  • Cell viability was assessed using MTT assay.
  • Apoptosis was detected via flow cytometry and TUNEL assay.
  • Gene expression levels of caspase-3, bcl-2, and bax were analyzed using RT-PCR.

Main Results:

  • Triptolide demonstrated dose- and time-dependent inhibition of pancreatic cancer cell growth.
  • TL treatment significantly increased apoptosis rates in SW1990 cells.
  • RT-PCR revealed significant up-regulation of caspase-3 and bax mRNA, while bcl-2 mRNA levels remained unchanged.

Conclusions:

  • Triptolide effectively induces apoptosis in human pancreatic cancer cells.
  • The observed apoptosis is likely mediated by the up-regulation of caspase-3 and bax gene expression.

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
Apoptosis01:30

Apoptosis

Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size reduction of the tissue.
Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or  immature dendritic cells. Non-professional phagocytes such as  epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes. 
Normal cells contain receptors that prevent them from being recognized by phagocytes.
