Protein arginine methyltransferase 5 (PRMT5) has emerged as a viable target in cancer therapy, providing novel treatment options beyond standard treatments. This enzyme is essential for several physiological activities, including gene control, RNA metabolism, and DNA repair. Dysregulation of PRMT5 has been linked to a variety of malignancies, making it a promising therapeutic target.
PRMT5 overexpression and upregulation have been reported in a variety of cancers, including prostate, breast, lung, and hematological malignancies. Its significance in tumor growth, metastasis, and therapy resistance makes it a promising target for therapeutic research. In preclinical investigations, inhibiting PRMT5 activity showed encouraging benefits, suppressing tumors and sensitizing cancer cells to chemotherapy and immunotherapy.PRMT5’s numerous activities in cancer biology make it an interesting therapeutic target. By suppressing PRMT5, researchers hope to disrupt crucial biological processes necessary for cancer cell survival and growth, potentially sparing normal cells. Furthermore, targeting PRMT5 may overcome resistance mechanisms associated with current cancer therapies, resulting in new therapy choices for individuals with refractory disease.

Several PRMT5 inhibitors are currently in research, with several advancing to preclinical and early clinical studies. These include Tango Therapeutics’ TNG462, Simcere Pharmaceuticals’ SCR-6920, and Jubilant Therapeutics’ JBI-778. These compounds specifically inhibit PRMT5 activity, providing a tailored approach to cancer treatment. Clinical study results have showed promising anti-tumor efficacy and controllable safety profiles, indicating that their therapeutic potential warrants further evaluation. In addition to cancer, PRMT5 inhibition is being used to treat autoimmune and inflammatory diseases, as well as microbial diseases. Preclinical studies have shown that PRMT5 is involved in T cell proliferation and immune response, implying that it may be useful in the treatment of autoimmune and inflammatory disorders. Furthermore, PRMT5 is involved in viral replication, making it a potential target for antiviral therapy against pathogens such hepatitis E virus.
The discovery of PRMT5-targeted therapies has the potential to change the treatment landscape for a variety of disease indications. In oncology, these therapies add a new dimension to combination therapy strategies, improving the efficacy of established treatments and combating drug resistance. Furthermore, its growth into non-oncological indications creates new therapeutic opportunities for unmet patient populations.
In conclusion, PRMT5 targeted therapies are a promising future in cancer treatment and beyond. PRMT5 inhibitors have the potential to improve patient outcomes by selectively inhibiting tumor development and sensitizing cancer cells to therapy. As researchers continue to understand the complexity of PRMT5 biology, these agents are poised to have a substantial impact on the future of medicine, providing new hope for people suffering from cancer and other debilitating disorders.
