Tid-1 Interacts with the von Hippel-Lindau Protein and Modulates Angiogenesis by Destabilization of HIF-1α
Bibliographic record
Abstract
The von Hippel-Lindau protein (pVHL) is a major tumor suppressor protein and also associated with the inhibition of angiogenesis via HIF-1alpha ubiquitination and proteasomal degradation. To further elucidate the biological activity of pVHL in angiogenesis, pVHL-interacting proteins were screened using the yeast two-hybrid system. We found that a mouse homologue of the long form of Drosophila tumor suppressor l(2)tid, Tid-1(L), directly interacts with pVHL in vitro and in vivo. Furthermore, Tid-1(L) protein; enhanced the interaction between HIF-1alpha and pVHL, leading to the destabilization of HIF-1alpha protein; therefore, Tid-1(L) protein decreased vascular endothelial growth factor expression and inhibited angiogenesis in vivo and in vitro. These findings propose that Tid-1(L) may play a critical role in pVHL-mediated tumor suppression by modulating the pVHL-dependent HIF-1alpha stability.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
