Abstract: Provided in the present disclosure is an antibody or fragment thereof against a human growth and differentiation factor 15 (GDF15). Further provided in the present disclosure is the use of the antibody or fragment thereof in the preparation of a drug for treating diseases or conditions. The antibody or fragment thereof provided in the present disclosure can bind to human GDF15 with high affinity and specificity, blocks the interaction of GDF15 with receptor GFRAL thereof, and has a longer half-life period in vivo in comparison with antibodies of the same kind.

Abstract: Provided is an antibody molecule or antigen-binding fragment thereof capable of binding to the human PD-L1. Also provided is the use of the antibody molecule or antigen-binding fragment thereof in the preparation of a medicament for treating tumors or cancers. Compared with the existing anti-PD-L1 antibodies, the provided antibody has superior affinity and dissociation rate for PD-L1, lower immunogenicity, and better tumor inhibition effects.

Abstract: A method for predicting the responsiveness of a cancer cell to an MEK inhibitor, comprising detecting the presence of at least one mutation in one or more genes selected from the group consisting of ADAM12, COL14A1, TNN, and TP53, in the cancer cell, by contacting a nucleic acid sample derived from the cancer cell with at least one oligonucleotide which allows specific detection of the mutation; wherein presence of mutation in ADAM12, COL14A1, TNN, TP53 and/or any combination thereof is indicative of decreased responsiveness of the cancer cell to the ERK inhibitor.
