Title (EN) ANTI-CKAP4 MONOCLONAL ANTIBODY
(FR) ANTICORPS MONOCLONAL ANTI-CKAP4
(JA) 抗CKAP4モノクローナル抗体
Abstract:
(EN) The purpose of the present invention is to provide an anti-CKAP4 monoclonal antibody that inhibits the binding of DKK1 and CKAP4 and exhibits an exceptional antitumor effect. Provided is an anti-CKAP4 monoclonal antibody that recognizes at least part of the 451-455 region, at least part of the 481-485 region, at least part of the 502-510 region, at least part of the 503-524 region and at least part of the 585-590 region, or at least part of the 585-592 region of the amino acid sequence (amino acid sequence of CKAP4) represented by SEQ ID NO: 1 as an epitope, the anti-CKAP4 monoclonal antibody effectively inhibiting the binding of DKK1 and CKAP4, the activation of AKT of S2-CP8 cells, and the proliferative ability of S2-CP8 cells or the migratory ability of S2-CP8 cells, and exhibiting an exceptional antitumor effect. The ability to develop ELISA methods in which these anti-CKAP4 monoclonal antibodies are used furthermore makes it possible, for example, to measure the serum CKAP4 in pancreatic cancer patients, and therefore also contributes to the development of companion diagnostic agents.
(FR) Le but de la présente invention est de fournir un anticorps monoclonal anti-CKAP4 qui inhibe la liaison de DKK1 et CKAP4 et présente un effet antitumoral exceptionnel. L'invention concerne donc un anticorps monoclonal anti-CKAP4 qui reconnaît au moins une partie de la région 451-455, au moins une partie de la région 481-485, au moins une partie de la région 502-510, au moins une partie de la région 503-524 et au moins une partie de la région 585-590 ou au moins une partie de la région 585-592 de la séquence d'acides aminés (séquence d'acides aminés de CKAP4) représentée par SEQ ID NO : 1 en tant qu'épitope, l'anticorps monoclonal anti-CKAP4 inhibant efficacement la liaison de DKK1 et CKAP4, l'activation de l'AKT des cellules S2-CP8 et la capacité de prolifération des cellules S2-CP8 ou la capacité migratoire des cellules S2-CP8, et présentant un effet antitumoral exceptionnel. La capacité de développer des procédés ELISA dans lesquels ces anticorps monoclonaux anti-CKAP4 sont utilisés, permet en outre, par exemple, de mesurer la CKAP4 sérique chez des patients atteints d'un cancer du pancréas et contribue, donc, également, au développement d'agents de diagnostic complémentaires.
(JA) 本発明の目的は、DKK1とCKAP4の結合を阻害して優れた抗腫瘍効果を奏する抗CKAP4モノクローナル抗体を提供することである。 配列番号1に示すアミノ酸配列(CKAP4のアミノ酸配列)の451~455位の領域の少なくとも一部、481~485位の領域の少なくとも一部、502~510位の領域の少なくとも一部、503~524位の領域の少なくとも一部且つ585~590位の領域の少なくとも一部、又は585~592位の領域の少なくとも一部を、エピトープとして認識する抗CKAP4モノクローナル抗体は、DKK1とCKAP4の結合やS2-CP8細胞のAKTの活性化、S2-CP8細胞の増殖能、又はS2-CP8細胞の遊走能を効果的に阻害して、優れた抗腫瘍効果を奏する。更に、これらの抗CKAP4モノクローナル抗体を用いたELISA法を開発できたことにより、例えば、膵癌患者の血清CKAP4の測定が可能となるため、コンパニオン診断薬の開発にも寄与する。
