Insights

Cas proteins like p130Cas/BCAR1 and Nedd9 are crucial for mammary cell functions. Aberrant signaling involving these proteins drives breast cancer initiation, progression, invasiveness, and drug resistance.

Area of Science:

  • Cellular Biology
  • Molecular Oncology
  • Signal Transduction

Background:

  • Cas proteins (p130Cas/BCAR1, Nedd9, EFS, CASS4) are essential scaffold proteins.
  • They integrate signals from growth factors, hormones, and extracellular matrix.
  • Cas proteins regulate mammary cell proliferation, survival, and differentiation.

Purpose of the Study:

  • To review the role of p130Cas/BCAR1 and Nedd9 in breast cancer.
  • To examine their involvement in mammary cell transformation.
  • To investigate their contribution to invasiveness and drug resistance.

Main Methods:

  • Review of in vitro studies
  • Analysis of mouse models
  • Examination of clinical data

Main Results:

  • Altered Cas protein expression leads to aberrant signaling cascades.
  • These alterations promote breast cancer initiation and progression.
  • p130Cas/BCAR1 and Nedd9 pathways are key to mammary cell transformation.

Conclusions:

  • Cas proteins are critical regulators of mammary cell fate.
  • Dysregulation of p130Cas/BCAR1 and Nedd9 signaling drives breast cancer.
  • Targeting these pathways may offer therapeutic strategies for breast cancer.

Assembly of Signaling Complexes01:30

Assembly of Signaling Complexes

Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
