Types of Cancer

Coquilla, D. September 2023

Cancer, a complex group of diseases characterized by the uncontrolled growth and spread of abnormal cells, manifests in various forms, each having distinct characteristics and molecular profiles. Your interest in exploring the role of proteins and antibodies in various types of cancer can indeed pave the way for identifying novel compounds and molecules for disease management, aligning well with your research background. Here, I’ll delve into a few main types of cancer and discuss the roles of various proteins and antibodies associated with them:

  1. Breast Cancer
    Proteins and Genes Involved:

HER2 (Human Epidermal Growth Factor Receptor 2): Overexpression is found in a subset of breast cancers.
ER (Estrogen Receptor) and PR (Progesterone Receptor): Hormone receptors playing significant roles in breast cancer progression.

Targeted Therapies:

Trastuzumab: A monoclonal antibody targeting HER2.
Tamoxifen: Targets the estrogen receptor.

  1. Lung Cancer
    Non-Small Cell Lung Cancer (NSCLC)
    Proteins and Genes Involved:

EGFR (Epidermal Growth Factor Receptor): Mutations often found in NSCLC.
ALK (Anaplastic Lymphoma Kinase): Rearrangements are targets for therapy.
Targeted Therapies:

Erlotinib: Targets EGFR.
Crizotinib: Targets ALK.
Small Cell Lung Cancer (SCLC)
Proteins and Genes Involved:

BCL-2: Overexpressed in SCLC, promoting cell survival.
Targeted Therapies:

Venetoclax: BCL-2 inhibitor.

  1. Colorectal Cancer
    Proteins and Genes Involved:

KRAS: Mutations are common and associated with resistance to EGFR inhibitors.
BRAF: Mutations signify a subset with poor prognosis.
Targeted Therapies:

Cetuximab: Targets EGFR, particularly in patients without KRAS mutations.
Vemurafenib: Targets BRAF.

  1. Prostate Cancer
    Proteins and Genes Involved:

AR (Androgen Receptor): Plays a significant role in the development and progression.
Targeted Therapies:

Abiraterone: Targets androgen production.
Enzalutamide: AR inhibitor.

  1. Melanoma
    Proteins and Genes Involved:

BRAF: Mutations are common in melanoma.
Targeted Therapies:

Dabrafenib: BRAF inhibitor.
Trametinib: Targets MEK, downstream of BRAF.

  1. Leukemia
    Chronic Myeloid Leukemia (CML)
    Proteins and Genes Involved:

BCR-ABL: A fusion protein driving the disease.
Targeted Therapies:

Imatinib: A tyrosine kinase inhibitor targeting BCR-ABL.
Your research could potentially delve into exploring the molecular mechanisms of these and other proteins and antibodies involved in different cancers, aiding in the identification of novel therapeutic targets. Moreover, the development of new antibodies or small molecules to modulate the function of these proteins could be a promising approach in cancer therapy.
