Intratumoral microbiome promotes liver metastasis and dampens adjuvant imatinib treatment in gastrointestinal stromal tumor.

Understanding the determinants of long-term liver metastasis (LM) outcomes in gastrointestinal stromal tumor (GIST) patients is crucial. We established the feature selection model of intratumoral microbiome at the surgery, achieving robust predictive accuracies of 0.953 and 0.

The Ran-binding protein RanBPM can depress the NF-κB pathway by interacting with TRAF6.

Ran-binding protein in microtubule-organizing center (RanBPM) has been reported to interact with the neurotrophin receptors p75NTR and TrkA, meanwhile p75NTR and TrkA can also interact with TRAF6. Whether RanBPM interacts directly with TRAF6 has not yet been established. In this study, using a yeast two-hybrid system and glutathione-S: -transferase pull-down assays, we determined that RanBPM binds to the TRAF6 C-terminus through its SPRY motif.

Tissue-specific distribution of aberrant DNA methylation associated with maternal low-folate status in human neural tube defects.

This study compares the density and tissue-specific distribution of 5-methyl cytosine (5mC) in genomic DNA from human fetuses with or without neural tube defects (NTD) and examines whether low maternal serum folate is a possible correlate and/or risk factor for NTD. The results demonstrate significant hypomethylation of brain genomic DNA in NTD fetuses relative to controls (P<.01), as well as relative hypermethylation of skin and heart in NTD fetuses.

The Ran binding protein RanBPM interacts with TrkA receptor.

RanBPM as a novel binding protein can interact with neurotrophin receptor p75NTR and tyrosine kinase receptor Met which has a similar tyrosine kinase structure as receptor TrkA has. Whether RanBPM interacts with neurotrophin receptor TrkA has not been established to date. In this study, using yeast two-hybrid system, it was identified that RanBPM bound to the intracellular domain (ICD) of neurotrophin receptor TrkA through its SPRY motif.
