LIN28 inhibitor LI71 is primarily used in research and therapeutic applications targeting cancer and regenerative medicine. It works by inhibiting the LIN28 protein, which is known to play a role in cell proliferation and stem cell maintenance. By blocking LIN28, LI71 can potentially suppress tumor growth, particularly in cancers where LIN28 is overexpressed, such as certain types of breast, ovarian, and liver cancers. Additionally, it is being explored for its ability to enhance tissue regeneration and cellular reprogramming, making it a promising candidate for regenerative therapies. Its application extends to studying developmental processes and understanding the mechanisms of pluripotency in stem cells.
