"Therefore, these results show that the binding of USP50 with ASC protein to deubiquitinate K63‐linked polyubiquitination is a crucial step for inflammasome activation."

sparser
"We here demonstrate that the deubiquitinating enzyme USP50 binds to the ASC protein and subsequently regulates the inflammasome signaling pathway by deubiquitinating the lysine 63-linked polyubiquitination of ASC."

"Therefore, these results show that the binding of USP50 with ASC protein to deubiquitinate K63 linked polyubiquitination is a crucial step for inflammasome activation."

"Coimmunoprecipitation assays indicated that USP50 strongly binds to the ASC adaptor protein, although it also interacted weakly with NLRP3 (Fig. xref A)."

sparser
"Based on the interaction between USP50 and ASC protein, we next investigated whether USP50 knockdown affects inflammasome activation by analyzing the formation of ASC specks."

"USP50 deubiquitinates the ASC protein."

"The deubiquitinating enzyme, ubiquitin-specific peptidase 50, regulates inflammasome activation by targeting the ASC adaptor protein"

reach
"To further confirm our finding that USP50 deubiquitinates the ASC protein, we performed in vitro deubiquitination assays."

reach
"In conclusion, we here demonstrate a novel regulatory mechanism regarding the ASC protein which is deubiquitinated by USP50 and provide experimental evidence emphasizing the importance of a regulatory mechanism mediated by ubiquitination and deubiquitination in inflammasome activation."

reach
"However, the Flag-USP50 (C53S) mutant, did not affect polyubiquitination of the ASC protein, indicating that the Cys residue at position 53 is critical for the catalytic activity of USP50 deubiquitination of the ASC protein."

reach
"Ubiquitination of Flag-ASC proteins was significantly decreased in the presence of Flag-USP50 protein, indicating that USP50 directly deubiquitinates the polyubiquitination of the ASC protein."

reach
"Wild-type USP50 and the Flag-USP50 (H322A) mutant significantly deubiquitinated the ASC protein."

sparser
"These observations suggest that upon LPS treatment, mitochondrial STAT3 could induce CPT1a-USP50 binding by mediating USP50 expression, leading to CPT1a stabilization, an increase in FAO and higher ATP production."

sparser
"In comparison, in the LPS-treatedRosa26 LSL-MLS-mSTAT3 macrophage lysates, CPT1a pulled down much less USP50 (Figure xref C, IP Lane 1, xref A), suggesting that mitochondrial STAT3 could contribute to CPT1a stabilization by influencing CPT1a-USP50 binding, at least partially."

sparser
"Upon the LPS stimulation, mitochondrial STAT3 could induce CPT1a stabilization by promoting USP50 expression and facilitating CPT1a-USP50 binding, leading to a switch from glucose to an increased reliance on FAO for ATP production, which, in turn, further enhanced NF-κB nuclear localization, leading to a great amount of cytokine production."
