Apoptosis in liver carcinogenesis and chemotherapy

Area of Science:

• Oncology
• Molecular Biology
• Cell Death Research

Background:

• Hepatocellular carcinoma (HCC) presents a significant global health challenge.
• Hepatocarcinogenesis is characterized by a disrupted balance between cell proliferation and apoptosis.
• Anti-apoptotic signals dominate, overpowering death-inducing stimuli in HCC development.

Purpose of the Study:

• To review recent findings on molecular alterations in HCC that dysregulate apoptosis.
• To discuss the challenges associated with using apoptosis-inducing chemotherapeutics in HCC treatment.
• To highlight the need for targeted therapies against anti-apoptotic pathways in HCC.

Main Methods:

• Literature review of recent contributions on HCC molecular alterations.
• Analysis of studies focusing on apoptosis regulation in hepatocarcinogenesis.
• Examination of research on chemotherapeutic resistance in HCC cells.

Main Results:

• HCC cells exhibit diverse mutations affecting apoptosis regulation.
• These mutations confer resistance to pro-apoptotic signals and chemotherapeutic drugs.
• Deregulation of apoptosis is a key factor in HCC progression and treatment resistance.

Conclusions:

• Targeting anti-apoptotic signals is crucial for effective HCC therapy.
• Understanding molecular alterations is essential for developing novel treatment strategies.
• Overcoming resistance to death-inducing chemotherapeutics remains a significant challenge in HCC management.
