Piperlongumine mediated apoptosis in cervical cancer cells beyond docking predictions

Area of Science:

• Phytochemistry
• Molecular Biology
• Oncology

Background:

• Cervical cancer remains a global health challenge with limited therapeutic advancements.
• Existing treatments often lead to recurrence and long-term health issues, necessitating novel therapeutic strategies.
• Phytochemicals, such as Piperlongumine, offer promising avenues for alternative cancer treatments.

Purpose of the Study:

• To investigate the anticancer properties of Piperlongumine against cervical cancer cells.
• To elucidate the molecular mechanisms underlying Piperlongumine's effects on apoptosis and cell cycle.
• To evaluate Piperlongumine's potential as an alternative therapeutic agent for cervical cancer.

Main Methods:

• In silico molecular docking simulations were performed to assess Piperlongumine's interaction with key apoptotic proteins (Bcl-2, Bax, Bak).
• In vitro bioassays were conducted using SiHa cervical cancer cells to evaluate Piperlongumine's effects on cell viability, apoptosis, and cell cycle.
• Key molecular markers, including reactive oxygen species (ROS) levels and mitochondrial membrane potential, were analyzed.

Main Results:

• Molecular docking revealed favorable binding affinities of Piperlongumine with Bcl-2, Bak, and Bax.
• Piperlongumine significantly reduced cervical cancer cell viability and induced apoptosis, evidenced by increased nuclear condensation and decreased mitochondrial membrane potential.
• The compound promoted cell cycle arrest, increased ROS levels, and modulated the expression of pro- and anti-apoptotic genes.

Conclusions:

• Piperlongumine effectively targets the apoptotic pathway in cervical cancer cells.
• The findings suggest Piperlongumine holds promise as a potential therapeutic agent for cervical cancer.
• Further in vivo studies are warranted to validate its efficacy and therapeutic potential.
