A functional genomic approach, based on systematic data gathering, was used to characterize a family of proteins containing a tripartite motif (TRIM). A total of 37 TRIM genes/proteins were studied, 21 of which were novel. The results demonstrate that TRIM proteins share a common function: by means of homo-multimerization they identify specific cell compartments.

Therapy resistance still constitutes a common hurdle in the treatment of many human cancers and is a major reason for treatment failure and patient relapse, concomitantly with a dismal prognosis. In addition to "intrinsic resistance", e.g.

Exosomes play a role in cell communication by transporting content between cells. Here, we tested whether renal podocyte-derived exosomes affect the injury of glomerular endothelial cells in lupus nephritis (LN). We found that exosomes containing high levels of high mobility group box 1 (HMGB1) were released from podocytes in patients with LN, BALB/c mice injected with pristane (which induces lupus-like disease in mice), and cultured human renal glomerular endothelial cells (HRGECs) treated with LN plasma.

Background: TRIM28 plays a crucial role in maintaining genomic stability and establishing imprinting, facilitated by the diversity of KRAB zinc finger proteins. The SUMOylation of TRIM28 is essential for its function and is enhanced in the presence of the KRAB domain. Previously, we demonstrated that Kaiso, another factor capable of interacting with TRIM28, can promote its SUMOylation.

Tripartite motif-containing 47 (TRIM47) is a member of the TRIM family, which has E3 ligase activity and has been demonstrated to be involved in tumor development. In this work, we found that TRIM47 is highly expressed in head and neck squamous cell carcinomas (HNSCC) tissues. TRIM47 overexpression promoted HNSCC cell proliferation.

Most of the pyroptosis inhibitors targeted Gasdermin D (GSDMD) are functioning by restraining GSDMD-N (p30) oligomerization. For the first time, this work discovered a pyroptosis inhibitor taking effect by degrading p30 and GSDMD. As the principal bioactive constituent in Erigeron breviscapus, scutellarin (SCU) assumes a pivotal role in the realm of anti-inflammatory processes.
