Targeting proliferation and survival pathways in head and neck cancer for therapeutic benefit

引用

Chinese Journal of Cancer 2012年第7期31卷 319-326页

作者： daniel e. Johnson Departments of Medicine and Pharmacology & Chemical Biology University of Pittsburgh Cancer InstitutePittsburgh Pennsylvania 15213 USA

Head and neck squamous cell carcinomas (HNSCC) are common human malignancies with poor clinical outcomes. The 5-year survival rates for patients with advanced stage HNSCC have not changed appreciably in the past few decades, underscoring a dire need for improved therapeutic options. Recent studies have elucidated a key signaling axis, the eGFR-STAT3-Bcl-XL signaling axis, that is aberrantly activated in a majority of HNSCC and contributes to the proliferation and survival of malignant cells. Considerable effort is being placed on developing highly specific inhibitors of different components of this pathway. This review highlights the progress that is being made towards achieving potent inhibition of the eGFR-STAT3-Bcl-XL signaling axis in HNSCC and the promising therapeutic strategies that are currently under development for this disease.

Utilizing zebrafish and okadaic acid to study Alzheimer's disease

Neural Regeneration Research 2018年第9期13卷 1538-1541页

作者： daniel Koehler Frederick e.Williams Department of Pharmacology and experimental Therapeutics University of Toledo

Despite the many years of extensive research using rodent models to study Alzheimer＇s disease （AD）, no cure or disease halting drug exists. An increasing number of people are suffering from the disease and a therapeutic intervention is needed. Therefore, it is necessary to have complementary models to aid in the drug discovery. The zebrafish animal model is emerging as a valuable model for the investigation of AD and neurodegenerative drug discovery. The main genes involved in human AD have homologous counter- parts in zebrafish and have conserved function. The basic brain structure of the zebrafish is also conserved when compared to the mammalian brain. Recently an AD model was established by administering okadaic acid to zebrafish. It was used to test the efficacy of a novel drug, lanthionine ketimine-5-ethyl ester, and to elucidate its mechanism of action. This demonstrated the ability of the okadaic acid-induced AD zebrafish model to be implemented in the drug discovery process for therapeutics against AD.
