Abstract:
Tyrosine kinases are key regulators of breast cancer cell survival and proliferation. Ten years ago, we conducted a screen for protein kinases expressed in primary human breast tumors and cultured cancer cells. Here, we review the progress from the last ten years in understanding the functions of these kinases with a focus on breast cancer. Three themes emerge: (1). tyrosine kinases regulate proliferation through the MAP Kinase pathway, (2). tyrosine kinases regulate cellular survival through the PI3 Kinase-Akt pathway, and (3). the cell cycle is regulated through a complex series of serine-threonine kinases. Our improved understanding of these signaling cascades has led to novel strategies for therapeutic intervention in breast cancer.
Insights
Tyrosine kinases are crucial for breast cancer cell growth and survival. Recent research highlights their roles in proliferation via MAP Kinase and survival through PI3 Kinase-Akt pathways, informing new breast cancer therapies.

- Previous research identified key protein kinases in breast tumors and cancer cells.
Purpose of the Study:
- To review advancements in understanding tyrosine kinase functions in breast cancer over the past decade.
- To elucidate the specific roles of tyrosine kinases in breast cancer proliferation, survival, and cell cycle regulation.
Main Methods:
- Review of scientific literature and research findings from the last ten years.
- Analysis of signaling pathways regulated by tyrosine kinases in breast cancer models.
Main Results:

Enzyme-linked Receptors
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
