AI-Assisted Histopathology: Precision in Liver Disease Assessment
This research pioneers the integration of Second Harmonic Generation/Two-Photon Excitation Fluorescence (SHG/TPEF) microscopy with advanced AI image analysis to objectively quantify steatosis and fibrosis in unstained liver tissues. This approach overcomes the subjectivity of traditional semi-quantitative scoring, providing reproducible and fully quantitative evaluations of liver histopathology. The high correlation coefficients (0.85 for fibrosis, 0.76 for steatosis) between AI and expert pathologist assessments validate its utility for capturing subtle histological changes.
Sexual Dimorphism in MAFLD-HCC: Progression and Regression
The study highlights significant sexual dimorphism in MAFLD-HCC, revealing that male mice exhibit more severe disease phenotypes, including greater tumor burden and higher serum ALT levels. In contrast, female mice demonstrate a remarkable capacity for recovery, with substantial reductions in tumor number and hepatic steatosis following dietary intervention. This underscores the crucial importance of considering sex as a biological variable in preclinical research, as it profoundly influences disease progression and response to treatment.
Implications for Personalized MAFLD-HCC Treatment
The findings suggest that therapeutic strategies for MAFLD-HCC should be tailored to account for sex-specific differences. The enhanced recovery observed in female mice points towards potential hormonal influences or metabolic pathways that could be leveraged for targeted interventions. AI-enhanced digital pathology can facilitate the identification of sex-specific regression patterns, leading to more personalized and effective diagnostic and therapeutic approaches in clinical settings.

Histological & Biochemical Analysis
| Feature | Male Mice (Progression) | Female Mice (Progression) | Male Mice (Regression) | Female Mice (Regression) |
|---|---|---|---|---|
| Tumor Burden | Greater Tumor Burden | Less Severe Tumor Burden | Minimal Improvement | Substantial Reduction |
| Serum ALT | Significantly Higher | Elevated but Lower than Males | Minimal Change | Significant Reduction |
| Hepatic Steatosis (Tumor) | High | High | Minimal Reduction | Moderate Reduction |
| Hepatic Steatosis (Non-Tumor) | High | High | Significant Reduction | Substantial Reduction |
| Hepatic Fibrosis | Moderate | Moderate | Moderate Improvement | Moderate Improvement |
Sex-Specific Recovery Trajectories
The study conclusively demonstrates a pronounced sexual dimorphism in MAFLD-HCC recovery. Female mice exhibit a significantly enhanced metabolic and histological recovery following dietary normalization, particularly in the reduction of tumor number and hepatic steatosis. This finding is critical for understanding the biological basis of sex differences in liver disease and designing targeted interventions.
Key Takeaways:
- Female mice show enhanced capacity for metabolic and histological recovery.
- AI-assisted quantification confirms marked steatosis regression in females.
- Male mice exhibit minimal improvement despite dietary intervention.
- Sex hormones likely influence disease reversibility.
