Q

Proteomics

A

The study of all the proteins that get expressed within our body.

Because Proteomics are so close to the phenotype we can have a much deeper / better understanding on human health and disease.

Proteins - act as enzyme in the cells and signaling molecules between cells

So they are directly transmitting information to the Phenotype.

Example: We can have a more inside view of why disease react the way that they do.

Example: Can identify and monitor biomarkers by analyzing the proteins in the body fluids such as urine, serum, exhaled breath and spinal fluid.

Proteomics can also facilitate drug development by providing a comprehensive map of protein interactions associated with disease pathways

Protemos types can include:
Liver cell types
Kidney cell types
Brain cell types

Q

Metebolomics

A

The study of metabolites within the cells, biofluids, tissues and organisms.

Due to the interaction within the biological system, it can help find early detection of disease such as:
Alzheimer’s,

it can help with inflammation,

And provide diet strategies.

Helps identify viruses, bacteria and fungus that could be found on the human skin.

Large scale study of small molecules / metabolites found within cells, biofluids, tissues or organisms.

Best represent the molecular phenotype.

The study of the genetic analysis from genomes contained directly from the environment.

Analysis microorganism, which are found in bacteria, virus and fungus.

Microbial / Microorganism - small organism found within the environment in which you need a microscope to analyze.

Able to identify the bacteria found within the genome.

Provides information on characteristics that cause diseases. (Microbial)

Q

Cell

A

Building blocks of all living things.

Provide structure to the body.

Q

Mutation

A

Change in DNA, in which one or more nucleotides are:

Inserted, Deleted or Substituted with another gene.

Not all Mutations are bad and lead to cancer.

Some Mutations can happen when there are environment changes.

Q

Non Coding DNA

A

Majority of our DNA do not code for Protein

17
Q

Enzyme

A

Is a protein that speeds up the rate of a chemical reaction.

They help with:
breathing
digesting food
muscle and nerve function

18
Q

NGS (next generation sequencing)

A

Sequencing technology used to determine the order of DNA in the entire genomes and or target regions between DNA or RNA.

NGS:
Rapidly sequence entire genomes.
Identity RNA variants
Study rare cancer & tumor variants.

19
Q

RNA

A

Creates proteins through translation as well as carry genetic information to the cell.

Creates proteins by translation.
It carries genetic information that is translated by ribosomes into various proteins necessary for cellular processes.

20
Q

DNA Base Pairs

A
  1. Adenine (A)
  2. Cytosine (C)
  3. Guanine (G)
  4. Thymine (T)

Base Pairs:
AT
GC

21
Q

Exome Sequencing

A

Sequencing the genetic protein region of the genome to understand what may cause symptoms and disease.

It can also identify variants and cancer studies.

22
Q

Whole Genome Sequencing (WGS)

A

Sequencing the entire genome (3.2 billion base pairs) in a human

23
Q

Target Genome Sequencing (TGS)

A

Targets a certain area in the genome that allows researchers to find rare variants.

24
Q

Biomarker

A

A biological process that measures normal or abnormal elements within ones body like, diseases, treatments and medication.

EXAMPLE:
If we are testing blood pressure our marker would indicate what the likely hood is on having a stroke.

If we test for antibodies within the blood, we can indicate a particular disease or infection.

25
Q

Whole Genome Sequencing (WGS)

A

WGS = 6B x 30x

3.2 billion base pair of DNA

WGS reads every single letter in your genome (6 billion)
30 x.

Gives more accurate, in depth analysis of your genetic makeup and more insight to possible variants and disease.

26
