Linear ubiquitin chains generated by the linear chain assembly complex ( LUBAC ) play an important role in NF ‐κB activation. However, regulation of generation is not well characterized. Here, we identified two deubiquitinating enzymes DUB s), ovarian tumor with linkage specificity OTULIN /Gumby/ FAM 105B) and cylindromatosis CYLD that can cleave polyubiquitin interact via N‐terminal PNG ase/ UBA or UBX PUB domain HOIP , a catalytic subunit . interacts both even unstimulated cells.

Although biological resources are essential for basic and preclinical research in the oncological field, those of sarcoma not sufficient rapid development treatment. So far, some cell lines have been established, however, success rate was low established types were frequently biased. Therefore, an efficient culture method is needed to determine various sarcomas. Organoid a 3-dimentional that enables recapitulation tumor microenvironment reported higher than 2-dimentional culture. The purpose...

SHARPIN, an adaptor for the linear ubiquitin chain assembly complex (LUBAC), plays important roles in NF-κB signaling and inflammation. Here, we have demonstrated a LUBAC-independent role SHARPIN regulating melanoma growth. We observed that interacted with PRMT5, type II protein arginine methyltransferase, increased its multiprotein methyltransferase activity. Activated PRMT5 controlled expression of transcription factors SOX10 MITF by SHARPIN-dependent dimethylation inhibition...

Abstract Approximately 60–70% of EWSR1 -negative small blue round cell sarcomas harbour a rearrangement CIC , most commonly CIC-DUX4 . sarcoma (CDS) is an aggressive and often fatal high-grade appearing predominantly in children young adults. Although lines their xenograft models are essential tools for basic research development antitumour drugs, few currently exist CDS. We successfully established novel human CDS line designated Kitra-SRS developed orthotopic tumour xenografts nude mice....

Malignant giant-cell tumors are extremely rare bone sarcomas that transform from conventional during long periods of treatment. Owing to their rarity, no further analysis molecular pathogenesis exists, and thus, standard treatment has been established. Recently, organoid culture methods have highlighted for recapturing the tumor microenvironment, we applied succeeded in establishing patient-derived organoids (PDO) sarcomas. This study aimed investigate genomic characteristics our established...

Sarcoma is a rare type of cancer for which new therapeutic agents are required. Ferroptosis nonapoptotic cell death triggered by iron-mediated lipid peroxidation. We found that TFRC, an iron uptake protein, was expressed at higher levels in sarcoma lines than noncancer and carcinoma lines. Glutathione peroxidase 4 (GPX4) protects cells against ferroptosis, its inhibition using RAS-selective lethal 3 (RSL3) had antitumor effect more pronounced lines, particularly synovial cells, compared to...
