ABSTRACT
Tanshinone IIA (Tan IIA), a main active ingredient of salvia miltiorrhiza, has a wide range of antitumor effects, while its specific role and mechanism in head and neck squamous cell carcinomas (HNSCC) is not fully understood. Totally 59 primary HNSCC patients underwent two courses of induction chemotherapy before surgery. The association between expression of Fas-Associated Death Domain (FADD) and receptor interacting protein kinase 1 (RIPK1) and chemotherapy resistance and survival were evaluated. The cell counting kit-8 was used to detect the effect of Tan IIA on the activity of cisplatin in chemoresistant HNSCC cells through a series of in vitro experiments. The quantitative real-time reverse-transcription polymerase chain reaction, Western blot analysis and flow cytometry were used. FADD and RIPK1 expressions were differentially expressed in Chemosensitive and drug-resistant patients. Furthermore, patients with tumors exhibiting high expression of FADD and RIPK1 had significantly greater risk for chemoresistance and mortality than patients with tumors that had low levels of these proteins. Moreover, Tan IIA reduced the expression of RIPK1 and FADD in HNSCC chemoresistant cell lines, which could increase the chemosensitivity of cisplatin and promote apoptosis. Overexpression of RIPK1 led to attenuation of therapeutic effects of Tan IIA, which were mainly realized through regulation of the RIPK1-FADD-Caspase 8 complex. This study is the first to demonstrate the clinical value and role of FADD and RIPK1 in the treatment of HNSCC. This work establishes the proapoptotic effects of Tan IIA and its potential to enhance chemosensitivity in HNSCC by modulating the RIPK1-FADD-Caspase 8 complex.
