潘景軒教授于1991和2000年在中山醫(yī)科大學(xué)分別獲得碩士和博士學(xué)位。 1991年始在中山醫(yī)科大學(xué)病理生理學(xué)教研室任教, 1997年破格晉升副教授。1998-2006年在美國(guó)排名第一的癌癥中心¾德州大學(xué)MD Anderson癌癥中心(MD Anderson Cancer Center)從事抗癌藥物方面的科研工作,歷經(jīng)博士后、Research Associate 及Instructor。2006年通過"中山大學(xué)百人計(jì)劃"人才工程引進(jìn)回國(guó),全職任教授,博士生導(dǎo)師。潘教授是美國(guó)癌癥研究協(xié)會(huì)(AACR)和美國(guó)血液學(xué)會(huì)(ASH)會(huì)員, 曾多次參加AACR和ASH年會(huì),展示或報(bào)告研究結(jié)果。參與了6部教材和專著共18章的編寫,其中在《高級(jí)病理生理學(xué)》等3部百萬字以上的專著中任主編或副主編;貒(guó)后,主持申請(qǐng)了病理學(xué)和病理生理學(xué)廣東省重點(diǎn)學(xué)科,目前已獲得廣東省教育廳批準(zhǔn)。
[研究方向] 腫瘤分子靶向治療和腫瘤藥理
潘教授的長(zhǎng)遠(yuǎn)科研目標(biāo)在于通過比較正常和腫瘤細(xì)胞的生長(zhǎng)、增殖、存活和死亡的分子機(jī)制遴選腫瘤治療的分子靶點(diǎn),通過化學(xué)或生物學(xué)手段干預(yù)這些靶分子從而殺傷腫瘤細(xì)胞,進(jìn)一步通過應(yīng)用轉(zhuǎn)化試驗(yàn)建立癌癥病人合理化治療方案,以期提高腫瘤病人的存活率,改善生活質(zhì)量。
長(zhǎng)久以來,腫瘤化療藥物的治療指數(shù)therapeutic indices (toxic dose per therapeutic dose)過于狹窄,從而導(dǎo)致藥物同時(shí)也殺傷正常細(xì)胞,毒性作用較強(qiáng),造成病人對(duì)藥物不能耐受。隨著基因組計(jì)劃的完成和分子腫瘤學(xué)的發(fā)展,現(xiàn)已可能尋找和干預(yù)適當(dāng)?shù)陌蟹肿硬⑼ㄟ^化學(xué)或生物學(xué)手段特異性殺傷腫瘤細(xì)胞而正常組織得以保護(hù),這就是靶向治療方法(target-driven therapeutic approach)。
酪氨酸蛋白激酶因?yàn)槭羌?xì)胞增殖信號(hào)通路的重要分子而成為腫瘤治療的靶點(diǎn),第一個(gè)獲準(zhǔn)上市的分子靶向藥物就是酪氨酸蛋白激酶小分子抑制物STI571(imatinib)。但隨著臨床的廣泛應(yīng)用,耐藥現(xiàn)象日益突出,因此,篩選和研制新型的小分子酪氨酸激酶抑制物十分必要。潘教授參發(fā)現(xiàn)EXEL-0862(一種新型的小分子酪氨酸激酶抑制物)對(duì)原癌基因c-KIT和PDGFRa突變的白血病細(xì)胞有很好的抗癌效果, 并能抑制c-KIT下游的信號(hào)轉(zhuǎn)導(dǎo)。 該研究成果已發(fā)表于Blood和Leukemia;貒(guó)后,帶領(lǐng)課題組致力于研制有我國(guó)自主知識(shí)產(chǎn)權(quán)的酪氨酸激酶小分子抑制物。
潘教授對(duì)靶向ras 突變基因的法尼基轉(zhuǎn)移酶特異性抑制劑(FTI) 的抗腫瘤特性和藥理機(jī)制進(jìn)行了系列研究,發(fā)現(xiàn)了新的藥理作用機(jī)制。潘教授發(fā)現(xiàn)FTI通過誘導(dǎo)活性氧(ROS)產(chǎn)生而導(dǎo)致DNA損傷,激活DNA損傷的感知蛋白ATM 和 DNA-PK,后兩者使得DNA-PK、 Brca1 和 Nbs1等重要修復(fù)蛋白均發(fā)生磷酸化,激活DNA修復(fù)機(jī)制。而DNA修復(fù)被認(rèn)為是引起癌細(xì)胞產(chǎn)生耐藥的重要因素。用化學(xué)或生物學(xué)方法干預(yù)DNA修復(fù)可能使得癌細(xì)胞對(duì)FTI變得敏感,這一研究將開辟以機(jī)制為基礎(chǔ)的FTI與DNA修復(fù)抑制剤的聯(lián)合應(yīng)用,以期增強(qiáng)殺傷癌細(xì)胞的能力。由于這一發(fā)現(xiàn)重要,研究成果被選為腫瘤學(xué)權(quán)威雜志Cancer Research的封面和Featured articles (Pan J et al. 65:3671-3781, 2005)。后來也應(yīng)Cancer Research的邀請(qǐng),撰寫了FTI作用機(jī)制方面新進(jìn)展的綜述文章。
潘教授在美國(guó)發(fā)表的較高質(zhì)量的SCI論文已有12篇, 其中第一作者或共同第一作者9篇。
潘景軒教授有志于組建一只腫瘤分子靶向治療和腫瘤藥理方面的科研團(tuán)隊(duì), 歡迎有興趣、有事業(yè)心的同學(xué)加盟.
