過去幾十年尤其是在靶向治療和免疫治療不斷取得突破, 患者的生存期也得到顯著的提升。但是，幾乎所有的癌癥病人都會(huì)出現(xiàn)耐藥，并且由于耐藥機(jī)制不明，大部分病人沒有合適的藥物替代方案。因此，探索腫瘤耐藥機(jī)制不僅可以使我們發(fā)現(xiàn)新的生物學(xué)現(xiàn)象并闡明其分子機(jī)制，由此而針對(duì)性設(shè)計(jì)的逆轉(zhuǎn)耐藥的方案對(duì)可能擴(kuò)大腫瘤藥物在臨床上的適用范圍也有較強(qiáng)的臨床意義。
為達(dá)到研究目的，我們首先通過兩種互補(bǔ)的研究路徑來篩選出腫瘤耐藥相關(guān)分子：1）一種是利用實(shí)驗(yàn)室在功能基因組學(xué)篩選（例如體內(nèi)體外CRISPR/Cas9 sgRNA篩選）方面的專長(zhǎng)，發(fā)現(xiàn)與耐藥相關(guān)的分子；2）第二種路徑是從收集臨床樣本（例如成對(duì)的治療前藥物敏感樣本和治療后耐藥樣本），然后通過高通量的方法學(xué)，包括蛋白質(zhì)組學(xué)和下一代測(cè)序，推測(cè)出可能的耐藥相關(guān)機(jī)制。然后，我們會(huì)建立和優(yōu)化各種腫瘤模型包括腫瘤細(xì)胞系，類器官和病人腫瘤樣本和異體移植、以及可精確模擬人自然病程的自發(fā)小鼠腫瘤等模型，結(jié)合細(xì)胞生物學(xué)，分子生物學(xué)，生物信息學(xué)等相關(guān)技術(shù)， 來驗(yàn)證我們的生物學(xué)發(fā)現(xiàn)并闡明其分子機(jī)制。最后，根據(jù)其分子機(jī)制合理設(shè)計(jì)逆轉(zhuǎn)耐藥方案，并最終發(fā)掘臨床轉(zhuǎn)化的潛能。
我們實(shí)驗(yàn)室長(zhǎng)期招聘免疫學(xué)，分子生物學(xué)，生物信息方向的博士后、研究助理，每年也通過北生所統(tǒng)一招生招收博士生，歡迎有興趣的科學(xué)家加入到我們的隊(duì)伍！詳情見實(shí)驗(yàn)室網(wǎng)站: Xulab.com.cn。
My diverse research experience has reinforced my strong commitment to pursue the identification of mechanisms of cancer drug resistance and novel drug targets. I aim to develop highly effective therapeutic strategies to treat cancer. More specifically, targeting both cancer and immune cells is a novel and promising method with great potential to simultaneously eliminate the patient’s tumor and harness their immune system to more effectively combat cancer. In our lab, we aim to understand how best to personalize and optimize current cancer immunotherapy and targeted therapy efforts.
There has been rapid progress in the fields of cancer immunotherapy and targeted therapy in the past few decades: how we treat cancer has undergone a complete revolution, leading to greater success in cancer survival and enhanced quality-of-life for patients. However, there is still much to be learned beyond what we already know about cancer treatment. The number of long-term survivors still remains limited, and many cancer patients do not respond to treatment, develop resistance, or relapse after initial responsiveness. Mechanisms of cancer drug resistance are still largely unknown, mostly due to tumor inter-/intra- heterogeneity and/or the tumor micro-/macro- environment. Therefore, our research holds not only scientific significance in terms of its contributions to the development of novel biology discoveries, but also clinical significance through exploration of areas such as clinical validation, drug target discovery and novel drug combinations.
We first plan to identify players associated with drug response by employing two complementary approaches: 1) via functional genomic approaches (e.g. in vitro/In vivo CRISPR/cas9 sgRNA screens) with pre-clinical models; and 2) via high-throughput approaches (e.g. Proteomics) with clinical models (e.g. paired drug-na?ve tumors and drug-resistant samples). Next, we will dissect the putative mechanisms of drug resistance from multiple directions, including but not limited to modeling (e.g. cell lines, organoids, PDXs and/or spontaneous mouse tumor models) and molecular validation. Uncovering this novel biology will be essential for us to ultimately identify druggable pathways and biomarkers that may improve clinical decision-making for patients. LINK: Xulab.com.cn
