Project description:The medial nucleus of the trapezoid body (MNTB) contains a nearly homogeneous population of neurons, which are innervated by large glutamatergic nerve terminals called calyces of Held (CH). Key steps in maturation of CHs and MNTB neurons, including CH growth and competition, occur very quickly for most cells between postnatal days (P)2 and P6. Therefore, we characterized genome-wide changes in this system, with dense temporal sampling during the first postnatal week. We identified 541 genes whose expression changed significantly between P0-6 and clustered them into eight groups based on temporal expression profiles. Candidate genes from each of the eight profile groups were validated in separate samples by qPCR.
Project description:The aim of this study is to investigate the efficacy, safety, and survival benefit of etoposide plus cisplatin and irinotecan plus cisplatin in first-line therapy of non-primary pancreatic metastatic and/or unresectable gastrointestinal neuroendocrine tumor G3 type. In addition, the investigators will explore the resistance mechanisms of gastrointestinal neuroendocrine tumor G3, and screen out biomarkers that can predict the efficacy of chemotherapy.
