          Target Information

          The LAR4B gene, more accurately referred to as LARP4B (La Ribonucleoprotein Domain Family Member 4B), is associated with RNA-binding proteins that are crucial for various aspects of RNA metabolism, including RNA stabilization, translation, and cellular stress responses. LARP4B belongs to the La-related protein family, which plays significant roles in maintaining RNA stability and enhancing translation efficiency of certain mRNAs. It has been identified as a target in cancer research due to its involvement in tumor biology, particularly regulating tumor suppressive pathways and interacting with microRNA networks. Studies have shown that LARP4B expression is downregulated in prostate cancer tissues, indicating its potential role as a tumor suppressor. Moreover, it is linked with liver cancer and survival rates, reflecting its importance in cellular growth and proliferation. The regulation of LARP4B and its interactions with other cellular components underline its potential therapeutic implications for cancer treatment.
