Abstract: The invention provides an isolated antibody or a fragment thereof, which is directed to the human chemokines CXCL1, CXCL7 and CXCL8, said antibody or fragment being capable of binding to the human chemokine CXCL1 with an equilibrium dissociation constant (KD) of at most 16 nM, to the human chemokine CXCL7 with an equilibrium dissociation constant (KD) of at most 5 nM and to the human chemokine CXCL8 with an equilibrium dissociation constant (KD) of at most 45 nM, as determined by surface plasmon resonance. The invention also provides some applications of said isolated antibody.

Abstract: An in vitro method for predicting a likelihood of an individual having a cancer to efficiently respond to an anti-cancer treatment, said method including the steps: of a) measuring the level of nuclear expression of TRF2 in a biopsy obtained from said individual, b) comparing the level obtained in step a) to a reference value, and c) determining the predicted likelihood of said individual to efficiently respond to said anti-cancer treatment from the comparison performed in step b).

Abstract: The invention relates in particular to an in vitro or ex vivo method for predicting the response of a patient to treatment with at least one HER2-blocking agent, said method including the steps of: i) identifying the nucleotide at the rs3746083 polymorphic site, for at least one allele, in particular the two alleles of the gene coding the tristetraprolin protein, in a biological sample from said patient; and/or ii) determining the concentration of the tristetraprolin protein in a biological sample from said patient, wherein said patient is suffering from HER2-positive cancer.
