Species diversity analysis of commercial Mantidis Ootheca samples contaminated by store pests based on DNA metabarcoding

Liuwei Xu, Xiaoying Zhang, Hua Guo, Xia Yang, Zhimei Xing, Wenzhi Yang, Jian Zhang & Xiaoxuan Tian
Abstract Mantidis Ootheca (Sangpiaoxiao, mantis egg case) is a typical multi-origin Chinese medicinal material. The Chinese Pharmacopoeia stipulates that the Mantidis Ootheca originates from three species of Mantis: Tenodera sinensis, Statilia maculate, and Hierodula patellifera. However, Mantidis Ootheca mainly relies on field collection, which leads to confusion of its actual origin in the market. As the clinical use of Mantidis Ootheca with unknown original mantis species will pose potential risks to drug safety, it is...

Tilman L. B. Hölting, Florencia Cidre-Aranaz, Dana Matzek, Bastian Popper, Severin J. Jacobi, Cornelius M. Funk, Florian H. Geyer, Jing Li, Ignazio Piseddu, Bruno L. Cadilha, Stephan Ledderose, Jennifer Zwilling, Shunya Ohmura, David Anz, Annette Künkele, Frederick Klauschen, Thomas G. P. Grünewald & Maximilian M. L. Knott
Abstract Chimeric fusion transcription factors are oncogenic hallmarks of several devastating cancer entities including pediatric sarcomas, such as Ewing sarcoma (EwS) and alveolar rhabdomyosarcoma (ARMS). Despite their exquisite specificity, these driver oncogenes have been considered largely undruggable due to their lack of enzymatic activity. Here, we show in the EwS model that – capitalizing on neomorphic DNA-binding preferences – the addiction to the respective fusion transcription factor EWSR1-FLI1 can be leveraged to express therapeutic genes....
