Abstract

Currently, there is little knowledge about transducin β-like protein 1 (TBL1) in tumor studies. Our previous studies reported immune cell-related TBL1 to be the key gene. Based on our searches of PubMed and the Web of Science, no studies have reported on the relationship between CTBL1 expression and the prognosis of PCa. Moreover, we have found certain signaling pathways that are significantly associated with CTBL1 in PCa. Little is known about the biological function of CTBL1 in PCa. Therefore, we decide to study the aberrant expression of CTBL1 and the relationship between CTBL1 and the signaling pathways in PCa. In the end, we will assess whether different CTBL1 expression is significantly associated with the prognosis of PCa. Biological function research and clinical feature associations could be superior evidence for the potential of TBL1 proteins to be potential targets for PCa therapy. Therefore, our study will provide a prospective research target for future studies on PCa. TBL1, identified as a component of the nuclear receptor corepressor (NCOR) complex, has been found to have the ability to regulate histone modification as well as gene transcription. Dysfunction of TBL1 is closely related to the occurrence and progression of human solid malignancy. Although TBL1 plays a crucial role in the development of some immune disorders and tumors, the biological role of cytoplasmic transducin β-like related protein 1 (CTBL1) remains unknown. A retrospective analysis of medical records was systematically conducted to uncover the functions of CTBL1 in malignant tumors and other diseases. Pathological and clinical records provided us with an unprecedented opportunity to explore the significance of CTBL1 in level posed tissue microarray (TMA). CTBL1 was over-expressed in PCa tissues by analyzing gene expression datasets.
