Deciphering the inositol-requiring enzyme 1 (IRE1) signaling pathway is fundamentally important for understanding the unfolded protein response (UPR). The ubiquitination of proteins residing on the endoplasmic reticulum (ER) membrane has been reported to be involved in the UPR, although the mechanism has yet to be fully elucidated. Using immunoprecipitation(More)
Exosomes are 30-120 nm-sized membrane vesicles of endocytic origin that are released into the extracellular environment and play roles in cell-cell communication. Tumor-associated macrophages (TAMs) are important constituents of the tumor microenvironment; thus, it is critical to study the features and complex biological functions of TAM-derived exosomes.(More)
Isoliquiritigenin (ISL) is an important flavonoid component of licorice and has been reported to possess anti-inflammatory and antioxidant properties, but its exact mechanism of action remains poorly understood. Previously, we demonstrated that ISL could suppress IL-6 expression in multiple myeloma. Here, we further characterized the anti-inflammatory(More)
Suppression of c-Myc is likely to induce cellular senescence in many tumors with unclear mechanisms. A proteomics survey indicated that high levels of BCL2-associated athanogene 2 (BAG2) were found in response to c-Myc repression in TRE293 cells. This observation led to the investigation into the role of BAG2 in c-Myc-induced senescence. The association of(More)
UNLABELLED Mammalian target of rapamycin complex 1 (mTORC1) plays important roles in regulating cell growth and proliferation, and the aberrant activation of mTORC1 has been observed in many human diseases. However, the proteins regulated by mTORC1 activation and their roles in mTORC1 downstream functions are still poorly understood. Using proteomic(More)
UNLABELLED Quantitative proteomic analysis was performed using iTRAQ to discover colorectal cancer (CRC)-related proteins in tissue interstitial fluids (TIFs). A typical inflammation-related CRC mouse model was generated using azoxymethane-dextran sodium sulfate (AOM-DSS), and TIFs were collected from these mice in four stages during CRC development. Using(More)
Mouse model induced by azoxymethane (AOM) and dextran sodium sulfate (DSS) is generally accepted as an ideal object to study on the carcinogenesis mechanisms of human colorectal cancer (CRC). The genomic responses to the AOM/DSS treatment in mouse that possibly lead to elucidation of CRC pathological mechanism are still poorly understood. For the first(More)
Cathepsin D is reportedly to be closely associated with tumor development, migration, and invasion, but its pathological mechanism is not fully elucidated. We aimed to evaluate phenotypic changes and molecular events in response to cathepsin D knockdown. Lowering endogenous cathepsin D abundance (CR) induced senescence in HeLa cells, leading to reduced rate(More)
