Mechanisms of Acute Coronary Syndromes and Their Implications for TherapyPeter Libby, M.D.N Engl J Med 2013; 368:2004-2013

The notion that heart attacks develop from coronary-artery stenosis is an oversimplification of a process involving lipid metabolism, inflammation, macrophage activation, collagen breakdown, and …….plaque rupture……(not always)

NO Endothelial Relaxation

Nitric Oxide cycle and vascular relaxation/vascular stiffness

Genome Wide Association studies (GWAS)

• Genome-wide association studies (GWAS) aim to identify causative genes for common disease such as diabetes, obesity and stroke by

• analysing single nucleotide polymorphisms (SNPs).• SNPs are identified that show association with a

disease, • they are unlikely to be the actual genetic variant

involved in causation of that disease• most individual SNPs for common diseases raise risk by

about only 20-40%

Genetic Links in Common Disease

• variants in the same gene confirmed link between APOC3 and early-onset heart attack

• APOC3, involved in fat metabolism, may delay the catabolism of triglyceride-rich particles

• Polymorphisms in the human APOC3 gene and promoter have been associated with

• • lipoprotein profile• • cardiovascular health• • insulin (INS) sensitivity

Melanoma Drugs approved by FDA

• a B-Raf inhibitor aimed to treat melanoma patients harboring V600E mutation

• a MEK inhibitor that was shown in phase III clinical trials to be efficient for treating melanoma patients with BRAF V600E or V600K mutations

• These new two drugs are now joining the first two drugs approved in 2011 to treat metastatic melanoma that are already in clinical use

Companion Diagnostics Testing

• The introduction of the two drugs was co-approved in concert with the THxID BRAF test from BioMérieux.

• This PCR-based BRAF test is designed to determine whether a melanoma patient harbors the V600E or V600K BRAF gene mutation and will assist directing the correct treatment to be given to patients.

• this companion diagnostic approved for BRAF mutation detection follows the approval of Roche’s cobas 4800 BRAF V600 Mutation Test in August 2011

• the association of diagnostics with treatments is a step further by pharmaceutical and diagnostic companies toward establishing personalized medicine

New test gives better stratification for prognosis of CLL

• Innovation Department - Hospital Clinic Barcelona

• classify CLLs into 3 new prognostic groups: • • MBC-like • • intermediate• • NBC-like• using only 5 epigenetic biomarkers

epigenetic signature has independent prognostic impact

• used bisulfite pyrosequencing primers designed to detect methylation of the 5 biomarkers.

• There are four possible formats to develop this test:

• • Pyrosequencing• • PCR + restriction enzymes• • Hybridization• • Immunoprecipitation + qPCR

Rationale of Innovation

current classification of M-CLL (mutated) and U-CLL (unmutated) is not used in clinical protocols to decide upon patient treatment and follow-upAfter 10 years only

Group Need Treatment (%)MBC-like 20

Intermediate 43

NBC-like 100

This test will allow

• - Improve the quality of life of CLL patients• - Improve management strategies that are

more adjusted to the biology of this disease• - Reduce the health care costs

EpigenomeThe suite of epigenetic modifications, collectively forming a dynamic epigenetic code, has long been known to operate as the manager of the genomic blueprint,

wielding cell-dependent control over gene expression at discrete times throughout development.

Our understanding of the disease epigenome has expanded, with the inclusion of numerous gene mutations and epimutations involved in producing aberrant gene expression.

these findings form inextricable causal links between our underlying genome, a dynamic epigenome, and the functional (disease) consequences stemming from both.

Non-Invasive Test for Early Detection of Colorectal Tumors

Dr. Guro Elisabeth Lind and a team from Oslo University Hospital have identified altogether 12 epigenetic biomarkers for early detection of colorectal cancera six-gene panel could outperform several previously published epi-markers, including VIM and SEPT9 which are included in commercial tests for early detection of colorectal cancer using stool and blood, respectively

a disease defined primarily by its genetic fingerprint

(NY Times) By GINA KOLATA Published: May 1, 2013 Jeff Boyd, Fox Chase

the similarity among breast, ovarian and endometrial tumors was the best example yet of the idea that cancers are more usefully classified by their gene mutations than by where they originate.

CD47 in cancer immunity

• Evasion of immune recognition is a major mechanism by which cancers establish and propagate disease.

• Recent data has demonstrated that the innate immune system plays a key role in modulating tumor phagocytosis through the CD47-SIRPα pathway.

• Careful development of reagents that can block the CD47/SIRPα interaction may indeed be useful to treat many forms of cancer

Akt in cancer

• Mechanisms for Akt pathway activation include • loss of tumor suppressor PTEN function, • amplification or mutation of PI3K, • amplification or mutation of Akt, • activation of growth factor receptors, • inactivation of the translation repressor protein

4E-BP1, and • exposure to carcinogens.

• Akt knockout mice demonstrate that Akt is required for both cancer cell survival and oncogenic transformation.

• That activation of Akt is oncogenic, could be explained by

preventing normal apoptosis of cells, thereby enabling accumulation of more oncogenic mutations in these cells.

Akt controls many cancer related cellular processes such as • cell metabolism, • growth and survival, • proliferation, and • motility, all of which contribute to tumor initiation and progression.

What are lncRNAs?

• Non-coding RNA is now known to make up the majority of transcribed RNAs and in addition to those that carry out well-known housekeeping functions (e.g. tRNA, rRNA etc), many different types of regulatory RNAs have been and continue to be discovered.

• Many of these non-coding RNAs are thought to have a wide range of functions in cellular and developmental processes.

• This large and diverse class of transcribed RNA molecules with a length of more than 200 nucleotides do not encode proteins.

• Their expression is developmentally regulated and lncRNAs can be tissue- and cell-type specific.

• A significant proportion of lncRNAs are located exclusively in the nucleus.

• They are comprised of many types of transcripts that can structurally resemble mRNAs, and

• are sometimes transcribed as whole or partial antisense transcripts to coding genes.

Types of molecular mechanisms that may be involved in lncRNA function

• The Signal archetype: functions as a molecular signal or indicator of transcriptional activity.

• The Decoy archetype: binds to and titrates away other regulatory RNAs or proteins.

• The Guide archetype: directs the localization of ribonucleoprotein complexes to specific targets.

• The Scaffold archetype: has a structural role as platform upon which relevant molecular components (proteins and or RNA) can be assembled.

Structural DNA nanotechnology [1] HybridizationThe self-association (self=assembly) of complementary nucleic acid molecules or parts of molecules, is implicit in all aspects of structural DNA nanotechnology

[2] Stably branched DNAthe combination of in vitro hybridization and synthetic branched DNA that leads to the ability to use DNA as a construction material[3] Convenient synthesis of designed sequences.Biologically derived branched DNA molecules, such as Holliday junctions, are inherently unstable, because

they exhibit sequence symmetry; i.e., the four strands actually consist of two pairs of strands with the same sequence.

Origami

DNA origami utilizes the genome from a virus together with a large number of shorter DNA strands to enable the creation of numerous DNA-based structures (Figure 1) The shorter DNA strands forces the long viral DNA to fold into a pattern that is defined by the interaction between the long and the short DNA strands

Reinventing as a way of life

Daniel Burrus, author of “Flash Foresight” wrote: “Today you cannot just reinvent now and then: to survive and thrive in a time of vertical change, you have to be redefining and reinventing yourself continuously. --- The organizations that are winning in the new century don’t bother competing; they leapfrog the competition by redefining anything and everything about their business.”

The ultrafiltration alternative for Hormones & Therapeutic Drugs

Imagine an automated workstation dedicated to rapidly prepare plasma ultrafiltrates. This workstation does not require centrifugation, and the same vessel used to prepare the ultrafiltrate, will be presented to an immunoanalyzer with a regular menu of immunoassays for measuring “Total” hormones and drugs. The ultrafiltrate will allow us to measure “Free” hormones and drugs. The workstation will be integrated in an automated line, and a standalone workstation will be available for labs that are not automated.

Drug Failures

• Drug failure rates, the cost to develop drugs and healthcare costs are at an all-time high.

• These facts are what are driving the new paradigm in drug development.

Companion Diagnostics

The value companion diagnostics bring to pharma lies in their ability to mitigate risk.

They can be the difference between drug approval and failure.

Increasingly, pharma companies are integrating companion diagnostic programs

and are developing them in conjunction with their drug development programs.

Companion diagnostics can provide an extra layer of protection and

a way for pharma companies to get efficacious drugs on the market

without presenting safety risks to discrete patient cohorts.
