Biomarkers
1- Clinical Biomarkers (Disease state)2- Cellular Biomarkers (Cell function)
What is a Clinical Biomarker?
An indicator for the presence of a disease state in Human
Clinical Biomarkers
1- Diagnostic Clinical Biomarkers (Indicator or predictive of existed Diseases)2- Prognostic Clinical Biomarkers (provide knowledge about the cause or development of a disease or even recovery of a disease)
Identification of Clinical Biomarkers in Human Body
1- Human Tissues (e.g. Liver, Spleen, Pancreas, etc.)2- Human Primary Cells (e.g. Adipocytes, Macrophages,
Platelets,etc.)3- Human Body Fluids (e.g. Cerebrospinal fluid (CSF),
Blood (Plasma, Serum), Saliva (extracellular fluid, etc.)

In a scientifically context, Systems Biology can be referred as “the use of a combination of all techniques and knowledge (or develop novel
ones) to find answer to any biological and medical questions
Standard Systems Biology: Identification of Biomarkers for different diseases in
Human Plasma?
1- Biological Knowledge
2- Molecular Knowledge
3- Cellular Knowledge
Advantages Disadvantages
1- Not suitable to find clinical biomarkers (proteins) for diseases in blood at present
2- Not suitable for the detection of very low abundant proteins at present
This indicates that an innovative and original strategy is essential to detect the disease at a very early stage in the patients for the
therapy

Is correct or not correct to use the word Biomarker ?
NO
Approximately 100 biomarkers for Cardiovascular Diseases (CVDs) NO
Approximately 40 biomarkers for Diabetes (T2D) NO
WHY THE ANSWER IS NO?
Based on defined clinical Biomarkers, it is not allowed to preselect for discovery of clinical Biomarkers. It is not allowed to remove any fraction from whole proteome samples. Clinical Biomarkers Discovery has to be executed in whole intact System.
The best situation 1-4 Clinical Biomarkers for one specific disease, Multifactorial diseases are exceptions from this potential law.

Obesity is a problem of epidemic-pandemic proportions and is related to poor health
Body needs fat
Abdominal Obesity is a major cause of Abdominal Aortic Aneurysm (AAA)
Adipose Tissue Structure
Adipose tissue (1)
1- Storage of energy in the form of triglycerides (TG) for lean times
2- The largest endocrine organ
What is the main cause of obesity?
An overload of energy (TG) in the adipose tissue and in particular adipocyte-associated LDs is the
main cause of obesity
What is main function of adipose tissue?
Obesity is defined as BMI (kg/m2) determined by the increasing mass of adipose tissue (BMI above 30 is obese)
Adipose tissue (2)
An inflammatory state of adipose tissue contributes to the development of insulin resistance (IR) and type 2 diabetes (T2D)
Obesity promotes an inflammatory state
What is the link between obesity and pathophysiological diseases?

LIPID DROPLETS

Plasma lipoproteins
Lipoprotein structure VLDL HDL
Disturbances in plasma lipoprotein homeostasis result in dyslipidemia, e.g. hypertriglyceridemia, hypercholesterolemia and etc., which in turn have serious pathophysiological consequences like CVDs

Adipose tissue is considered as an immune organ
Objective
Why do I make this statement?
Conventional wisdom: immune functionality is the result of adipose tissue macrophages (ATM).
My research challenges this notion: Adipose tissue adipocytes (ATA) exhibit immune cell function
No body measured such function in human primary adipocytes or other human AT-associtaed cells alone
1-Classical hypothesis: necrotic AT-adipocytes (ATA) in obese state activate AT-macrophages (ATM) that then lead to a sustained chronic inflammation in AT (Only in AT).
2-The link between human adipocytes and the source of inflammation in AT has not been systematically studied.
3-AT is considered as an immune organ
3-Our hypothesis: human primary adipocytes are able to prime inflammation in AT.
Classical hypothesis versus my research challenges
Measure to know?
Challenges
1-the adipose tissue adipocytes (ATA) exhibit immune cell function
2-Adipose tissue can be potentially considered as a new organ to compensate hormone/enzyme disorders
3-Mitochondria is inactive in obese adipocytes and LDs are “the only boss” in adipocytes
4-A homeostatic balance between lipoproteins may guarantee a regulated function of lipoproteins, -and not the quantity of a specific lipoprotein
5-Human primary adipocytes produce and secrete Insulin
Macrophages Characteristic production1-Cytokines
2-Chemokines
3-MHC-II molecules
4-CDs
5-Adhesion Molecules
We must show that adipocytes are also able to produce similar products!

Migration assay according to Boyden Chamber
Are adipocytes-associated components biologically functional?
YES
Summary
Preadipocytes and adipocytes synthesize immune-associated components (genes and proteins)
Since preadipocytes and adipocytes express immune-associated genes, expression of these genes suggested to be a bona fide property of this cell type
Since these genes and proteins response to LPS, They are biologically active
Since adipocytes-associated MCP-1 and IP-10 are able to activate CD4+, They are biologically functional.
Human primary adipocytes exhibit immune cell function.
Conclusion
Adipocytes are able to prime inflammation
Adipocytes Produce Insulin
the role of adipocytes behind the link between obesity and insulin regulation in human is unknown
The overload of lipid droplets with triglycerides in adipocytes is the main cause of obesity and its afflictions
such as insulin resistance
Adipocytes Produce Insulin?
RESULTS 2
Hypothesis: Fat determines the concentration of insulin
insulin concentration and human patients
Bariatric Surgery Heals Type 2 Diabetes
Assumption: the production of insulin by human adipocytes is not from pancreas
Insulin stain in pancreas of prediabetes BB rats
Insulin in control RATs
Insulin in other human primary cell types
The novel knowledge obtained by the present study could help to re-design future studies related to insulin and therapy of diabetes.
Human adipocytes constitutively synthesize and secrete insulin and that is biologically functional.
Human primary adipocytes secretes insulin but preadipocytes do not and that suggested to be due to the lipid droplets
Conclusion
Insulin expression in a variety of human cell types including the adipocytes is an evidence for a ubiquitous insulin expression
Data suggested a cross talk between AT and pancreas to tune up energy metabolic system
A homeostatic balance between lipoproteins may guarantee a regulated function of lipoproteins, and not the quantity of a
specific lipoprotein?

Found very interesting paper by Head of Mass Spectrometry of OCDEM (University of Oxford)
The majority of apolipoproteins and proteins involved in lipid metabolism are conserved between the different lipoproteins.
The known phospholipids are also conserved between the different lipoproteins.
Human diseases related to proteins carried by VLDL and LDL can be divided in three major categories: 1 – dyslipidaemia, 2 –atherosclerosis and vascular disease, and 3 – coagulation disorders.
A variety of proteins present on LDL and VLDL strongly supports that protein shuttling through lipoproteins may be involved in the regulation of biological processes
SUMMARY
CONCLUSION
A homeostatic balance between lipoproteins may guarantee a regulated function of lipoproteins, and not the quantity of a
specific lipoprotein

A NOVEL METHOD FOR QUANTITATIVE PROTEOMICS
I developed a novel method, which increases the number of quantified proteins from 20 to 300 or even more in
plasma research and you do not need to run a gel (That is a revolution contribution in proteomics).
This approach is applicable to any good samples
With this approach, we are able to find easily the candidate protein(s) (diagnostic or prognostic markers) in any
patients (CVDs, T1D, T2D, Obesity, Coagulation Disorders)
This approach is applicable to all spieces (e.g. Bacteria, Viruses)
