[Expression of T cell factor 4 in renal cell carcinoma]
1Department of Urology, First Hospital, Beijing Medical University, Beijing 100034, China.
Objective:
To investigate of the transduction of Wnt/Frizzled pathway in nuclei and the function of TCF4 (T Cell Factor) in renal cell carcinoma.
Methods:
TCF4 mRNA are tested through RT-PCR and Northern Blot in renal cancer tissue and renal cancer cell strain (GRC-I).
Results:
It has been certificated that TCF4 are expressed in renal cell carcinoma, at the same time, there are some different splice of TCF4 in renal cancer. A new 300bp mutant gene are found.
Conclusion:
TCF4, an important molecular of Wnt/Frizzled pathway, takes part in the formation and progression of renal cell carcinoma, different splice of TCF4 is one of the mechanism.
Insights
T Cell Factor 4 (TCF4) is expressed in renal cell carcinoma, with alternative splicing contributing to cancer development. This Wnt/Frizzled pathway molecule plays a role in renal cancer progression.
Area of Science:
- Molecular Biology
- Oncology
- Genetics
Context:
- The Wnt/Frizzled pathway is crucial in cellular processes.
- Dysregulation of this pathway is implicated in various cancers.
- Renal cell carcinoma (RCC) pathogenesis requires further molecular elucidation.
Purpose:
- To investigate the nuclear transduction of the Wnt/Frizzled pathway.
- To determine the role of T Cell Factor 4 (TCF4) in renal cell carcinoma.
- To identify novel molecular mechanisms in RCC development.
Summary:
- TCF4 mRNA expression was analyzed in renal cancer tissues and cell lines using RT-PCR and Northern Blot.
- TCF4 expression was confirmed in renal cell carcinoma.
- Alternative splicing variants of TCF4, including a novel 300bp mutant, were identified in renal cancer.
Impact:
- TCF4 is identified as a significant molecular player in the Wnt/Frizzled pathway's involvement in RCC.
- Alternative splicing of TCF4 represents a novel mechanism contributing to renal cancer formation and progression.
- Findings provide insights into the molecular basis of RCC and potential therapeutic targets.
