The present invention relates to a peptide bound to CD44v6 and uses for inhibiting cancer metastasis using the same, and the peptide of the present invention specifically binds to CD44v6 and inhibits it, thereby inhibiting cancer cell migration and metastasis. The peptides of the present invention selected two peptides (v6Pep-1 and v6Pep-2) that bind well to cells with high expression of human CD44v6 protein using phage peptide display technology and it was confirmed that it interferes with the binding between c-Met and CD44v6 to inhibit cancer cell migration. The peptide of the present invention is relatively stable in serum and shows a high potential as an anticancer treatment agent that suppresses metastasis due to the progression and migration of cancer in the future.

The invention described herein provides antibodies or antigen-binding fragment thereof specific for an epitope within the variant exon v6 or v9 of the CD44 gene (CD44v6 or CD44v9), antibody-drug-conjugate (ADC) thereof, and other derivative comprising the antibodies or antigen-binding fragment thereof. The invention also provides nucleic acid molecules encoding the same, and methods of making the same. The invention further provides pharmaceutical compositions comprising the same, and the use of the same in treating diseases or in the manufacture of a medicament for the treatment of the diseases, such as cancer.

The invention relates to a fusion protein comprising a polypeptide of interest, a transmembrane domain and an HIV gag polypeptide, or their functionally equivalent variants. The invention also relates to the polynucleotides, vectors, host cells and virus-like particles expressing or presenting said fusion proteins and to the pharmaceutical, immunogenic or vaccines composition containing said fusion proteins, polynucleotides, vectors, host cells and virus-like particles and their use in human and veterinary medicine.

The present disclosure relates to a modified cell comprising a polynucleotide encoding a secretable scFv binding SIGLEC-15 and/or encoding a dominant negative form of CD44. In embodiments, the modified cell further comprises an antigen-binding molecule, which for example, is a CAR comprising an antigen-binding domain, a transmembrane domain, and an intracellular signaling domain.

The present invention relates to methods for modulating efflux of drugs based on binding to a protein region of CD44 in part comprising the amino acid sequence specified in the provisional application referenced above, and incorporated in its entirety by reference herein (PROV).
