  • Patent number: 12508311
    Abstract: Disclosed are a fusion protein, and a preparation method and use thereof, which belong to the field of biomedicine technologies. The fusion protein comprises a polypeptide specifically bound to a KRas protein, a specific tumor-cell-penetrating peptide and a lysosome recognition peptide. The fusion protein with tumor targeting, penetrability and specific protein degradation is designed and constructed direct to an undruggable protein for the first time, thus providing a new idea for development of an anti-cancer targeted drug. Different from the prior art in which one molecule can only target one target protein, the fusion protein can simultaneously induce degradation of wild-type and mutant-type KRas proteins. Meanwhile, the fusion protein can improve the sensitivity of the KRas mutant-type tumor to the tumor-targeted drug by inducing degradation of KRas, thus expanding an application range of existing anti-cancer targeted drugs and having important significance in tumor clinic treatment.

  • Patent number: 12357690
    Abstract: In the present disclosure, the effect of the TGF?/Smad3/EPB41L5 molecular mechanism on cancer cells has been identified, and it has been found that high expression of EPB41L5 is correlated with poor overall survival of cancer patients, indicating that EPB41L5 is a potential prognostic marker of cancer. Thus, the present disclosure specifies an epitope of EPB41L5 to allow EPB41L5 to be recognized as an antigen, and relates to an antibody or a fragment thereof which binds specifically to the epitope. The antibody according to the present disclosure may be usefully employed as a therapeutic agent for EPB41L5-related cancer.
