The Ubiquitin Key and Omega-3 Shields

Biomedical Breakthroughs from the 6th International Bio-Medical Congress in Cyprus

November 2018 | Nicosia, Cyprus

The 6th International Bio-Medical Congress

The 6th International Multithematic Scientific Bio-Medical Congress (IMBMC), held in November 2018 at the European University Cyprus (EUC) in Nicosia, transformed the Mediterranean island into a global nexus for biomedical innovation.

Founded by Professor Ioannis Patrikios and internationally recognized for its scientific impact, this annual congress gathered Nobel laureates and leading researchers to tackle humanity's most persistent health challenges: cancer, neurodegenerative diseases, cardiovascular disorders, and aging 1 4 .

The congress earned significant recognition through publication in Nature's Cell Death & Disease journal, highlighting the quality of its scientific contributions 1 3 . With 18 Continuing Medical Education (CME) credits awarded and free public access, the event bridged cutting-edge research and clinical practice while fostering global scientific dialogue 4 .

Nobel Insights and Cellular Landscapes

Prof. Aaron Ciechanover
Nobel Laureate in Chemistry, 2004

Received an Honorary Doctorate from EUC and presented on the Ubiquitin Proteolytic System, illuminating cellular waste disposal machinery that regulates protein degradation 2 4 .

His insights revealed how malfunctions in this system contribute to cancer and neurodegenerative conditions, opening avenues for targeted therapies.

Prof. Wolfgang Graier
ER-Mitochondria Axis

Explored how calcium transfer between these organelles influences cellular health and disease:

  • Aging & Neurodegeneration: Dysfunctional crosstalk accelerates neuronal damage
  • Metabolic Disease: Disrupted signaling impairs insulin secretion
  • Cancer: Altered communication supports tumor survival 2

Epigenetics and Osteoarthritis

Professor Aspasia Tsezou connected epigenetics and osteoarthritis (OA), identifying hsa-miR-33a as a critical regulator of cholesterol metabolism in chondrocytes. This microRNA serves as both a serum biomarker for OA progression and a promising therapeutic target 2 .

Key Cellular Targets in Disease Pathology

Disease Key Molecule/Pathway Role in Pathogenesis Therapeutic Potential
Osteoarthritis hsa-miR-33a Inhibits cholesterol efflux → cartilage damage Biomarker & drug target
Neurodegeneration ER-Mitochondria Ca²⁺ flux Disrupted signaling → neuronal death Regulate organelle crosstalk
Cancer Ubiquitin-proteasome system Misfolded protein accumulation → tumor growth Proteasome inhibitors (e.g., bortezomib)

Omega-3 Fatty Acids and Cardiovascular Defense

Professor Philip C. Calder's exploration of omega-3 polyunsaturated fatty acids (PUFAs) offered transformative insights into cardiovascular disease prevention, combining epidemiological observations, clinical trials, and mechanistic biology 2 .

Research Methodology
  1. Epidemiological Discovery: High omega-3 consumption in Inuit populations correlated with low CHD mortality
  2. Interventional Trials: Supplementation with 300-1000 mg/day EPA/DHA
  3. Mechanistic Analysis: Measured impacts on lipids, inflammation, platelet function
  4. Meta-Analyses: Consolidated data from >100,000 participants 2
Key Findings
  • Triglyceride Reduction: 15-30% decrease in serum levels
  • Anti-Inflammatory Action: Suppressed pro-inflammatory eicosanoids
  • Plaque Stabilization: Reduced vulnerability in arteries
  • Clinical Impact: 10-15% reduction in cardiac events 2

Omega-3 Mechanisms in Cardiovascular Protection

Biological Mechanism Effect on Cardiovascular System Clinical Impact
Triglyceride Metabolism ↓ Hepatic VLDL synthesis ↓ Serum triglycerides by 15-30%
Anti-Inflammatory Action ↓ Eicosanoid production ↓ Plaque inflammation & endothelial damage
Plaque Stability ↑ Collagen cap thickness ↓ Risk of rupture & myocardial infarction
Anti-Arrhythmic Effect Stabilizes cardiac ion channels ↓ Sudden cardiac death

Revolutionizing Diagnostics and Therapy

Liquid Biopsies
Prof. Nickolas Papadopoulos

Presented breakthroughs in non-invasive cancer detection:

  • PapSEEK: Detects endometrial/ovarian cancers in Pap test fluid
  • UroSEEK: Identifies bladder cancer via urine analysis

These tests target minimal residual disease and early-stage tumors 2 4 .

Microneurotrophins
Prof. Achilleas Gravanis

Introduced small molecules that:

  • Boost neural stem cell differentiation
  • Reverse memory deficits in models
  • Penetrate the blood-brain barrier

Overcoming limitations of protein-based neurotrophins 2 .

Direct Oral Anticoagulants
Prof. Alex Spyropoulos

Redefined perioperative DOAC management:

  • Heparin "bridging" increased bleeding risk
  • Patient-specific protocols proved safer

Based on renal function and pharmacokinetics 2 .

The Scientist's Toolkit

Essential research reagents and resources presented at IMBMC 2018:

Reagent/Resource Function Application Example
Ubiquitin-Proteasome Inhibitors Block targeted protein degradation Cancer therapy (e.g., bortezomib)
hsa-miR-33a Mimics/Antagomirs Modulate cholesterol transport genes Osteoarthritis biomarker & treatment
Omega-3 PUFA Concentrates EPA/DHA supplements (≥80% purity) Cardiovascular risk reduction trials
Circulating Tumor DNA (ctDNA) Cancer-derived DNA fragments in biofluids Early detection (PapSEEK/UroSEEK)
Microneurotrophins Small-molecule neurotrophin receptor agonists Stimulate brain repair in neurodegeneration

Conclusion: A Catalyst for Global Health Innovation

The 2018 IMBMC transcended a typical scientific meeting—it ignited collaborations with lasting biomedical impact. From Ciechanover's Nobel-prized ubiquitin machinery to Calder's omega-3 epidemiology, the congress showcased how fundamental biology translates into lifesaving applications.

The research presented has since propelled clinical innovations: liquid biopsies are entering screening programs, microneurotrophins are advancing in trials, and omega-3 guidelines are evolving. As Professor Patrikios envisioned, this Cyprus-based congress remains a beacon of "academic excellence, research, and innovation"—proving that small islands can drive giant leaps in human health 2 4 .
