S100A4

S100A4蛋白全稱為鈣結合蛋白S100A4，也被稱為轉移素或p9Ka，是一種多功能小分子蛋白。它通過與細胞內不同靶點結合，影響細胞骨架動態變化，促進細胞運動及侵襲能力，尤其在腫瘤轉移過程中扮演關鍵角色。S100A4常與乳腺癌、結直腸癌等多種惡性腫瘤的侵襲性生長和遠端擴散密切相關，其高表達常提示患者預后不良。此外，在肺纖維化、類風濕性關節炎等慢性疾病中，S100A4也被發現參與組織異常重塑和炎癥反應調控。
近年來研究發現，抑制S100A4功能可有效減緩腫瘤轉移進程。多個研究團隊正在開發針對該蛋白的小分子抑制劑和單克隆抗體，其中部分化合物已在動物模型中顯示出阻斷癌細胞遷移的效果。某些已上市藥物如二甲雙胍被發現具有間接調控S100A4表達的作用，這為老藥新用提供了潛在方向。學術界與制藥企業正通過結構生物學手段解析其三維構象，以期設計出更精準的靶向治療藥物。

IHC image of CSB-PA020632HA01HU diluted at 1:600 and staining in paraffin-embedded human lung tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.
