Context:
• Scientists have identified new biomarkers enabling non-invasive diagnosis of schizophrenia using cheek swabs.
Key Highlights:
- Scientific Discovery
• Biomarkers identified:
- Sp4 mRNA
- HSP60 protein
• Detectable via cheek swab (non-invasive method)
- Clinical Findings
• Higher levels found in schizophrenia patients
• Sp4 mRNA:
- Linked to severe symptoms and memory issues
• HSP60 protein: - Associated with slower reaction time
- Scientific Basis
• Sp4: Involved in neuronal development & synaptic plasticity
• HSP60: Linked to cellular stress response and immune function - Significance / Applications
• Enables early diagnosis
• Reduces need for invasive procedures
• Opens pathway for personalised treatment
Relevant Prelims Points:
• mRNA (Messenger RNA):
- Transfers genetic information for protein synthesis
• Biomarker: - Indicator of a biological condition
• Transcription Factor (Sp4): - Regulates gene expression
• HSP60: - Heat shock protein involved in stress response
Relevant Mains Points:
- Healthcare Innovation
- Shift towards non-invasive diagnostic tools
- Improves accessibility and patient compliance
- Mental Health Governance
- Early detection can reduce disease burden
- Supports integration into public health systems
- Scientific Advancement
- Links between genetics, immunity, and mental disorders
- Potential for precision medicine
- Challenges
- Need for large-scale validation
- Ethical concerns in genetic testing
- Accessibility in low-resource settings
