  专家简介: 

  谭明博士,1988年毕业于华西医科大学,获法医遗传学硕士学位。2000年获MD Anderson Cancer Center肿瘤生物学博士学位,随后5年在该医学中心从事博士后训练。2007-2011年期间担任南阿拉巴马大学助理教授,现任该校Mitchell癌症研究所终身副教授,细胞死亡和代谢研究中心首席科学家,肿瘤生物学中心主任。曾在Mol Cell, Mol Cell Biol,Cancer Cell,Mol Cancer,Cancer Res,Oncogene,J Biol Chem和Cell Death Dis等多个SCI杂志发表研究成果。

  Contribution to Science: 

  1. Oncogenic reprograming of cancer cell glucose metabolism: We found that oncogene ErbB2 overexpression leads to dysregulated cell metabolism by upregulate heat shock factor 1/LDHA, and targeting ErbB2 mediated dysregulation of glucose metabolism can overcome therapeutic resistance.

  2. HSF1 in cancer cell stress responsive signaling: We investigated the role of stress signals such as ROS, Heat Shock Factor 1 (HSF1) in cancer cell stress response and in drug resistance. We found that ROS plays an important role in cancer cell drug resistance and HSF1 can transcriptionally regulate ATG7 and autophagy and controls cancer cell chemosensitivity.

  3. Non-coding RNA and cancer stem cells in cancer therapeutic resistance: We are one of the first research groups to investigate the role of microRNAs in cancer resistance to chemotherapeutic agents. We find that miR-125b regulate Taxol-induced apoptosis through directly target BAK1 in breast cancer cells. In addition, miR-125b overexpression leads to cancer stem cell enrichment, which also contributes to miR-125b mediated therapeutic resistance.

  4. ErbB2 and its downstream signaling regulated cancer cell progression and drug resistance: We investigated the role of ErbB2 and its downstream signaling molecules such as Akt, HIF1a, and STAT3 in tumor progression and drug resistance. We also used TAT sequence to target a STAT3 inhibiting peptides to inhibit tumor growth in animal models.
