The cellular prion protein (PrPC) is linked to cancer progression, promoting tumor growth and metastasis. Targeting PrPC may offer new therapeutic strategies for various cancers.
Area of Science:
- Biochemistry
- Molecular Biology
- Oncology
Background:
- The cellular prion protein (PrPC) is a cell surface glycoprotein with diverse physiological roles.
- PrPC is implicated in neurodegenerative and prion diseases.
- Ectopic expression of PrPC is observed in numerous cancer types.
Purpose of the Study:
- To review the expression patterns of PrPC across different cancers.
- To discuss the role of PrPC in cancer development and progression.
- To explore PrPC as a potential therapeutic target for cancer treatment.
Main Methods:
- Literature review of studies on PrPC expression and function in cancer.
- Analysis of PrPC's involvement in cancer cell migration, invasion, and metastasis.
- Investigation of PrPC's downstream signaling pathways in tumorigenesis.
Main Results:
- PrPC is ectopically expressed in gastric, melanoma, breast, colorectal, and pancreatic cancers.
- PrPC promotes tumor growth, cellular migration, invasion, and metastasis.
- PrPC contributes to chemotherapy resistance and inhibits tumor cell apoptosis.
Conclusions:
- PrPC plays a significant role in the development and progression of various cancers.
- Altering PrPC expression or targeting its pathways could be a viable strategy for cancer therapy.
- Further research into PrPC's functions in oncology is warranted.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
