FoxD2-AS1 is a prognostic factor in glioma and promotes temozolomide resistance in a O⁶-methylguanine-DNA methyltransferase-dependent manner

Glioma is the most common brain tumor with a dismal prognosis. While temozolomide (TMZ) based chemotherapy significantly improves survival in glioma patients, resistance against this compound commonly leads to glioma treatment failure. Overexpression of long-noncoding RNA (LncRNA) FoxD2 adjacent opposite strand RNA 1 (FoxD2-AS1) was identified to promote glioma development, but the role in TMZ resistance remains unclear. In this paper, we found that FoxD2-AS1 was overexpressed in recurrent glioma, high FoxD2-AS1 expression was significantly correlated with poor patient outcome. Methylation of O⁶-methylguanine-DNA methyltransferase (MGMT) is significantly less frequent in high FoxD2-AS1 expression patients. Knockdown of FoxD2-AS1 decreased the proliferation, metastatic ability of glioma cells and promote the sensitivity to TMZ in glioma cells. Furthermore, knockdown of FoxD2-AS1 induced hypermethylation of the promoter region of MGMT. Our data suggested that FoxD2-AS1 is a clinical relevance LncRNA and mediates TMZ resistance by regulating the methylation status of the MGMT promoter region.

First Discussion about the Academic Thinking and the Clinical Experience of Febrile Disease of Shao School Inherited by Professor Shen ;Yuanliang / 浙江中医药大学学报

Objective] To summarize the academic thinking and clinical experience of febrile disease of Shao school inherited by Professor Shen Yuanliang. [Methods]This article discusses the formation and development of febrile disease of Shao school, presents Professor Shen Yuanliang's contribution to inheriting the academic thinking of febrile disease of Shao school, and his clinical experiences and prescriptions. The article also illustrates and analyses a medical record. [Results]Professor Shen Yuanliang inherits the academic thinking and clinical experience of febrile disease of Shao school. He pays attention to the inspection and abdomen examination, eliminating the pathogenic factor to treat exogenous diseases, and regulating spleen and stomach to treat endogenous diseases. He prefers using herbs with the feature of light, regulating and tonifying formula, and focuses on the care after the recuperation. The case mentioned is perfectly recovered after medication. [Conclusion]Professor Shen Yuanliang has the distinguished characteristics in therapy and the rich experience, and the clinical efficacy is obvious.
