Decoding the link between WWOX and p53 in aggressive breast cancer

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Basal-like breast cancer (BLBC) and triple-negative breast cancer (TNBC) are aggressive subtypes with poor outcomes.
• Limited understanding of molecular mechanisms hinders effective treatment strategies for BLBC and TNBC.
• Tumor suppressors WW domain-containing oxidoreductase (WWOX) and TP53 are frequently altered in these breast cancers.

Purpose of the Study:

• To review the functional interplay between WWOX and p53 in the context of BLBC and TNBC.
• To highlight signaling pathways regulated by WWOX and p53 relevant to breast cancer development.
• To elucidate how WWOX loss impacts BLBC and TNBC progression.

Main Methods:

• Literature review focusing on WWOX, p53, and breast cancer signaling.
• Analysis of studies investigating WWOX and p53 interactions.
• Synthesis of current knowledge on WWOX/p53 roles in estrogen receptor signaling, EMT, and genomic instability.

Main Results:

• WWOX loss is demonstrated to drive BLBC formation by deregulating p53 functions.
• WWOX and p53 regulate key pathways including estrogen receptor signaling and epithelial-to-mesenchymal transition (EMT).
• The interplay between WWOX and p53 significantly influences genomic instability in breast cancer.

Conclusions:

• WWOX plays a critical role in suppressing BLBC and TNBC development.
• Targeting WWOX-p53 interactions may offer novel therapeutic strategies for aggressive breast cancers.
• Further research into WWOX and p53 signaling is crucial for advancing BLBC and TNBC management.
