靶點詳情

  • 最新研究進(jìn)展：
        甲胎蛋白（Alpha-fetoprotein，AFP）是一種由胎兒肝臟和臍帶組織合成的血漿蛋白質(zhì)，一直以來都是臨床上廣泛應(yīng)用的腫瘤標(biāo)志物之一。近年來，AFP在以下幾個方面取得了一些新的研究進(jìn)展：
        腫瘤治療：AFP在肝癌治療中被廣泛研究。最新的研究表明，AFP作為一種治療監(jiān)測指標(biāo)，能夠預(yù)測肝癌手術(shù)后的療效和預(yù)后，為臨床治療提供重要參考。
        胎兒先天性疾病篩查：AFP也被用于胎兒先天性疾病的篩查。最新的研究表明，AFP與其他標(biāo)志物聯(lián)合檢測可以有效地篩查胎兒神經(jīng)管缺陷和某些常見的先天性心臟病等疾病。
        AFP作為一種干細(xì)胞標(biāo)記物：最近的研究表明，AFP在干細(xì)胞研究中也具有重要作用。AFP被發(fā)現(xiàn)與某些類型的干細(xì)胞有密切關(guān)系，如肝臟干細(xì)胞和胚胎干細(xì)胞等，可以作為這些干細(xì)胞的標(biāo)記物進(jìn)行鑒定和分離。
        甲狀腺疾?。鹤钚碌难芯窟€發(fā)現(xiàn)，AFP可能與甲狀腺功能紊亂和甲狀腺癌等疾病有關(guān)。AFP可以作為一種檢測甲狀腺癌和甲狀腺功能異常的新的生物標(biāo)志物，具有潛在的臨床應(yīng)用價值。
        總之，AFP作為一種重要的腫瘤標(biāo)志物和胎兒先天性疾病篩查指標(biāo)，在腫瘤治療和妊娠管理等方面已經(jīng)廣泛應(yīng)用。最新的研究還發(fā)現(xiàn)AFP在干細(xì)胞研究和甲狀腺疾病等領(lǐng)域具有重要的應(yīng)用前景，未來將進(jìn)一步拓展其臨床應(yīng)用價值。

    19. Antibody therapy targeted at AFP-producing tumor cells showed an inhibitory effect on the PI3K/AKT pathway via the liberation, restoration and functional stabilization of PTEN.
