Physcion Induces Potential Anticancer Effects in Cervical Cancer Cells

Area of Science:

• Cell biology
• Cancer research
• Pharmacology

Background:

• Investigating the effects of physcion on HeLa cells.
• Assessing morphological and ultrastructural changes induced by physcion.

Purpose of the Study:

• To elucidate the antitumor mechanism of physcion.
• To evaluate physcion's impact on cell viability, cell cycle, and key molecular pathways.

Main Methods:

• Optical, fluorescence, and electron microscopy for ultrastructural analysis.
• MTT assay for cell viability.
• Flow cytometry for cell cycle, apoptosis, mitochondrial potential, and reactive oxygen species (ROS) analysis.
• Western blotting (implied by protein expression analysis) for LC3 and Bcl-2 protein levels.

Main Results:

• Physcion inhibited HeLa cell viability and induced G0/G1 cell cycle arrest in a dose-dependent manner.
• Physcion activated autophagy, evidenced by increased lysosomes, autophagosomes, and LC3 protein expression.
• Physcion induced oxidative stress, altering nuclear and mitochondrial structures, and promoted apoptosis via caspase-3/7 activation and reduced Bcl-2 expression.

Conclusions:

• Physcion demonstrates an antitumor effect through the induction of oxidative stress, autophagy, and apoptosis.
• The findings suggest physcion as a potential candidate for cervical cancer therapy.
