Breast Cancer (BC)

Breast cancer (BC) is a complex and devastating disease that has a profound impact worldwide. The demand for the development of highly effective drugs and therapies to combat this condition cannot be emphasized enough. As a pioneering company specializing in rare oncology, we are fully committed to offering comprehensive services for the advancement of BC drug and therapy development.

Overview of Breast Cancer (BC)

Breast cancer, a malignancy originating from breast cells, is a prevalent tumor worldwide, constituting approximately 12.5% of newly diagnosed cancer cases annually. Although it can affect both males and females, it is more commonly found in women. The defining characteristic of breast cancer is the uncontrolled growth and division of abnormal cells within the breast tissue. These anomalous cells can invade nearby tissues and potentially spread to distant locations in the body, a process known as metastasis. 

Pathogenesis of Breast Cancer (BC)

  • Genetic Factors: Certain gene mutations, such as BRCA mutation, are associated with an increased risk of developing BC.
  • Hormonal Factors: Hormonal imbalances, such as high estrogen levels or prolonged exposure to estrogen, can contribute to BC development.
  • Family History: Having a first-degree relative (parent, sibling, or child) with BC increases the risk of developing the disease.

Targets of Breast Cancer (BC) Therapy

Estrogen Receptors (ER)

ER-positive BC relies on estrogen signaling for growth and proliferation. Targeting ER with selective estrogen receptor modulators (SERMs) or estrogen receptor downregulators (ERDs) can disrupt this signaling and inhibit tumor growth.

Progesterone Receptors (PR)

PR-positive BC is also dependent on progesterone signaling. Targeting PR can be an effective strategy for hormone receptor-positive BC therapeutics.

Human Epidermal Growth Factor Receptor 2 (HER2)

HER2-positive BC is characterized by overexpression of the HER2 protein. Targeting HER2 with monoclonal antibodies or small molecule inhibitors can effectively inhibit HER2-driven tumor growth.

PI3K/AKT/mTOR Pathway

This signaling pathway plays a crucial role in BC cell survival and proliferation. Targeting key components of this pathway, such as PI3K, AKT, or mTOR, can be an effective strategy for BC.

Cell Cycle Regulators

Disruption of cell cycle regulation is a hallmark of cancer, including BC. Targeting cell cycle checkpoints, such as cyclin-dependent kinases (CDKs), can prevent cancer cell division and induce cell death.
