UDP‐Glucose‐6‐Dehydrogenase Mediated O‐GlcNAcylation of Tight Junction Protein 1 Suppresses Metastasis in Renal Cell Carcinoma

Advanced Science, EarlyView.
Our research unveiled a regulatory paradigm wherein TRIM25 orchestrates the ubiquitin‐mediated degradation of UGDH. UGDH modulates the protein stability of TJP1 by regulating O‐GlcNAcylation levels, effectively impeding the metastasis of ccRCC. Our insights elevate UGDH to a pivotal biomarker and tumor suppressor, marking the first demonstration that ...

MÖSSBAUER STUDY OF YTTERBIUM ETHYLSULPHATE

Le Journal de Physique Colloques, 1974
The hf parameters and the relaxation rate of Yb3+ in YbES are deduced from the 170Yb Mössbauer spectra between 1.3 and 30 K. The shielding factors R ࣃ 0.24 and σ2 ࣃ 0.61 are derived from the experiments. The thermal variation of the relaxation rate observed between 8 and 25 K shows an additional exponential term to the previously observed Orbach and ...
