研究方向
主要從事細胞氧化還原調控的分子機理研究。
細胞的氧化還原調控失衡是導致亞健康、衰老、神經退行性疾病、炎症、腫瘤、糖尿病等的重要因素，因此，細胞氧化還原調控的分子機理研究具有重要理論和實際意義。
近年研究發現：機體在應激條件下產生的一氧化氮等活性氮及活性氧小分子通過對蛋白質中氧化還原敏感的半胱氨酸巰基進行修飾，影響蛋白的結構、活性、定位、組裝和降解，從而調控蛋白的功能和細胞信號傳導，最終在生理和病理過程中發揮作用。這種修飾稱為氧化還原依賴的蛋白翻譯後修飾（Redox based post-translational modification of protein），包括：亞硝基化修飾(-SNO)、不同程度的氧化修飾（-S-S-; -S-OH; -SO3）、谷胱甘肽化修飾(-SSG)等，與磷酸化修飾一樣，是兩種進化上高度保守的蛋白翻譯後修飾之一。我們致力於揭示生命活動中這些小分子和大分子的對白，揭示氧化還原依賴的蛋白質巰基翻譯後修飾在細胞命運和疾病發生中的作用。重點研究一氧化氮生物活性及其對蛋白巰基的亞硝基化修飾在細胞信號轉導中的作用。主要有以下三個方面。
1、蛋白質巰基修飾的功能和方法研究。
2、氧化應激/氮應激（oxidative stress/nitrosative stress）在疾病發生髮展中的作用機理以及天然產物/中醫藥的調控和套用。
3、肌醇磷脂4位激酶phosphatidylinositol 4-kinase type IIα (PI4KIIα)和一氧化氮代謝調控蛋白S-nitrosoglutathione reductase (GSNOR)的功能與分子機制研究。
主要貢獻
主持國家自然科學基金重點項目1項，面上項目4項。作為首席科學家主持國家重大科學研究計畫（蛋白質研究）1項，作為課題負責人承擔國家重大研究計畫一項。主持“863”計畫探索項目1項，主持中科院青年創新基金和創新青年科學家小組課題各1項。在Free Radical Biol Med, J Cell Sci, Nucleic Acids Res, Oncogene等發表SCI論文39篇,申請國家發明專利兩項，撰寫兩本書籍章節。
主要成果
揭示了亞硝基化修飾在調控蛋白核質轉運中的作用，發現一氧化氮通過亞硝基化修飾調控核輸出受體CRM1的功能，擴展了對核輸出調控機制和一氧化氮生物學功能的認識。揭示了亞硝基化－泛素化－SUMO化三種蛋白質翻譯後修飾的相互調控，本工作提示：調控其它蛋白質翻譯後修飾可能是巰基亞硝基化修飾發揮作用的重要途徑。
揭示了NO代謝調控對學習記憶的調控作用，率先提出NO生物活性受合成和代謝雙調控的觀點，部分揭示了NO代謝酶GSNOR在神經系統的生理意義。
發展定量高通量亞硝基化檢測方法解決了內源亞硝基化檢測難題；發現和排除了亞硝基化檢測中的假陽性信號，引起本領域的廣泛關注；尤其是我們建立了不可逆親和素標記方法（IBP）, 是目前唯一能排除分子間二硫鍵干擾及-SSH巰基修飾的特異亞硝基化檢測方法。
發現新的腫瘤生長調控蛋白Phosphatidylinositol 4-kinase type IIα，PI4KIIα. 該蛋白α亞型特異地調控HER-2/PI3K，ERK1/2 信號通路，調控HIF-1α蛋白的合成，影響了HIF-1下游促血管生成因子VEGF，iNOS等蛋白的表達，影響內皮細胞的成管及遷移能力進而影響血管新生，最終調控腫瘤的生長目前我們已構建PI4KIIα轉基因鼠，正在進行PI4KIIα在腫瘤細胞轉移方面的機理研究。

NO, as a putative messenger, is implicated in physiological and pathological processes. Apart from the well-known cGMP-dependent signaling pathway of NO, there is also a cGMP-independent pathway that involves S- nitrosylation. S- nitrosylation is a ubiquitous redox-related modification of cysteine thiols by nitric oxide, which transduces the bioactivity of NO. The mechanism and the cellular effects of this redox-based post-translational modification of proteins are not well understood. Our approach to understanding this process involves three aspects:
1) Investigation of the effects of NO on the properties of proteins, such as folding kinetics, stability, enzyme activity and protein-protein interactions, complex assembling. This part of the work provides a basis for the study of the cellular effects.
2) We are interested in investigating how SNO affects intracellular events, such as protein localization, protein-protein interactions, and how NO and SNO affect the apoptosis and differentiation cascade. We are also screening natural products for activity as anti-oxidative/nitrosative stress agents.
3) Investigation of the effects of NO and SNO at the level of the whole organism, such as in memory, diseases (diabetes, cancer, neurodegenerative diseases).
