The NLRP3 (NLR family pyrin domain containing 3) inflammasome is involved in diverse inflammatory diseases, thus strict control of its activation is necessary to prevent excessive inflammation. Protein ubiquitination has been reported to regulate the assembly, protein expression and activation of the NLRP3 inflammasome. Until now, several deubiquitinases (DUBs) have been reported to affect the degradation of NLRP3 through the proteasome pathway. However, there is no research on DUBs regulating NLRP3 degradation through macroautophagy/autophagy. Here,...

Early 2 factor (E2F) genes encoding a family of transcription factors are significantly associated with apoptosis, metabolism, and angiogenesis in several tumor types. However, the biological functions of E2F transcription factors (E2Fs) and their potential involvement in the malignancy of lower-grade glioma (LGG) remain unclear. We explored the effects of the expression of eight E2F family members on the clinical characteristics of LGG based on the Chinese Glioma Genome Atlas (CGGA), The Cancer Genome Atlas...
