Jinfukang induces cellular apoptosis through activation of

Area of Science:

• Oncology
• Pharmacology
• Molecular Biology

Background:

• Traditional Chinese medicine Jinfukang (JFK) shows promise for non-small cell lung cancer (NSCLC).
• Previous studies suggest JFK's anti-cancer effects involve epigenetic alterations.
• Understanding JFK's precise molecular mechanisms is crucial for its clinical application.

Purpose of the Study:

• To investigate the molecular mechanisms underlying Jinfukang's anti-cancer activity in lung cancer cell lines.
• To identify key genes and pathways affected by JFK treatment using transcriptome profiling.
• To elucidate JFK's role in inducing apoptosis and cell cycle arrest.

Main Methods:

• Transcriptome profiling (RNA-seq) was employed to analyze gene expression changes in A549 lung cancer cells treated with JFK.
• Gene ontology analysis was performed to identify significantly altered biological pathways.
• Gene knockdown experiments were conducted to validate the role of specific apoptosis-related genes.

Main Results:

• JFK significantly decreased lung cancer cell viability and altered cell morphology.
• JFK induced cell cycle arrest and apoptosis in A549 cells.
• RNA-seq identified 5,281 differentially expressed genes, with downregulation of cell cycle genes and upregulation of apoptosis-associated genes like Fas and death receptor 4 (DR4).
• Knockdown of Fas and DR4 partially abrogated JFK-induced apoptosis.

Conclusions:

• Jinfukang induces apoptosis in non-small cell lung cancer cells, specifically A549, through the activation of Fas and DR4.
• JFK's anti-cancer effects are mediated by the modulation of cell cycle and apoptosis pathways.
• This study provides valuable insights into the antitumor mechanisms of Jinfukang as a traditional Chinese medicine for NSCLC treatment.
