Abstract:
The epithelial-mesenchymal transition (EMT) is a process of cell transformation under certain physiological and pathological states in which epithelial cells are transformed into mesenchymal cells with fibroblast-like properties, which confers upon them the increased invasion and migration capabilities of cancer cells. Previous studies have demonstrated that SRY-related high-mobility-group box 4 (Sox4) protein coordinates EMT-related pathways and EMT-related transcription factors, thereby regulating the EMT process. The focus of this review is to evaluate recent advances regarding the role of Sox4 protein in the cancer EMT. First, we provide an overview of the general background of Sox4 (structure and function) and the EMT in cancer. Next, we introduce the interactions between Sox4 protein and various factors during cancer EMT. Finally, we suggest directions for future investigations. In general, the information compiled in this paper should serve as a comprehensive repository of information on the subject matter and contribute to the design of other research and future efforts to develop therapeutic strategies that target the Sox4 protein.

Elements Crucial for Effective Psychotherapy
The Therapeutic Alliance
The therapeutic alliance refers to the relationship between the therapist and the client. The alliance strengthens when the therapist and the client engage in a nurturing, supportive, trusting, empathetic, and respectful relationship, improving therapeutic outcomes. Therapists must monitor this relationship...
