Study Notes

Erythrocytes and Hemoglobin

The major protein of erythrocytes is hemoglobin.
Hemoglobin from sickle cell anemia patients, when subjected to electrophoresis, shows an abnormality, as discovered by Linus Pauling.
Linus Pauling concluded that the cause of sickling in sickle cell anemia is an abnormality in hemoglobin.

Protein Kinases

The complete set of protein kinase genes in the genome is called the kinome.
Human kinome refers to the complete set of protein kinase genes in the human genome.
There are over 20 FDA-approved therapeutic agents that target protein kinases.

Antibodies and Therapy

Antibody-based therapy is a characteristic of the pharmaceutical industry.
Antibodies do not directly kill cancer cells in cancer treatment.
A researcher associated with the DNA replication and cancer therapeutics group is not specified.

Cancer

Apoptosis evasion is a hallmark of cancer.
A function of Cdc7 kinase in DNA replication is to activate MCM complexes.
Mutations in protein kinases are associated with several cancers, such as lung, breast, and colorectal cancers.

Molecular Medicine

The primary focus of molecular medicine is the understanding of the molecular mechanisms of diseases.
Molecular medicine is defined as the application of molecular biology and genetics to the diagnosis, prevention, and treatment of diseases.

DNA Replication and Cancer

The unit of study that focuses on the DNA damage response and its relationship to cancer is molecular medicine.
Cdc7 inhibitors are used in cancer therapy to inhibit DNA replication.
The structure of Cdc7 kinase is a serine-threonine kinase.

CAR T Cell Therapy

CAR stands for Chimeric Antigen Receptor in CAR T cells.
Steps in CAR T Cell Therapy include: a) T cell collection, b) T cell genetic modification, c) T cell expansion, and d) T cell infusion.
