        Q&As (6)

        Ask a question
        Is the interaction between PLK4 protein and other proteins? 05/21/2023

        There is an interaction between PLK4 protein and other proteins. For example, it interacts with certain proteins on spindle fibers to regulate chromosome segregation, and with other proteins in signal transduction pathways to regulate cell proliferation and differentiation.

        What is the function of PLK4 protein in cell division? 12/04/2020

        PLK4 protein is mainly responsible for regulating the process of chromosome segregation and cytoplasmic division in cell division. It is associated with the assembly and function of spindle fibers, affecting the accuracy of chromosome segregation and cell division.

        Which biological molecules can be used as molecular markers of PLK4 protein? 11/30/2020

        Certain biomolecules can be used as molecular markers of PLK4 protein, such as mRNA or protein of PLK4 protein detected in biological samples such as blood and urine. These markers can be used for early diagnosis of disease, prognostic judgment, or monitoring of treatment efficacy.

        What is the current stage of research for the treatment of PLK4 protein? 08/11/2020

        Therapeutics targeting the PLK4 protein are still in the early stages of research. A number of small molecule inhibitors and antibody drugs have been developed and initially evaluated in laboratories and clinical trials. However, further research and clinical validation of these treatments are needed to determine their safety and efficacy.

        What are the therapeutic strategies for PLK4 protein? 08/04/2020

        Therapeutic strategies for PLK4 protein include inhibition of its activity, regulation of its expression, and gene therapy. For example, the development of small molecule inhibitors or antibody drugs against the PLK4 protein to inhibit its aberrant activity in tumors, or the regulation of PLK4 protein expression through gene knockout or overexpression techniques.

        Does abnormal PLK4 protein expression cause disease? 06/07/2020

        Studies have shown that the abnormal expression of PLK4 protein is associated with the occurrence of a variety of tumors, including but not limited to brain cancer, lung cancer, breast cancer, pancreatic cancer, etc. It may be related to aspects such as proliferation, metastasis, and drug resistance of tumor cells.
