Abstract

fetched live from OpenAlex

Overcoming local DNA rigidity is required to perform three-dimensional DNA-protein configuration at promoter regions. The abundant architectural nonhistone chromosomal HMG box proteins are nonsequence-specific; however, they have been established to specifically recognize distorted DNA. Using transient transfection to overexpress two different members of the HMGB-1/2 family of DNA architectural factors, we demonstrate that these proteins provide a general enhancement in reporter gene expression irrespective of the promoter being considered. Evidences are also provided indicating that stimulation may not be achieved by recruitment of the proteins by regulatory factors or as a consequence of major chromatin unfolding as previously suggested. Interestingly, the influence of the HMG box proteins under study was overridden when the promoters were either induced or stimulated by Trichostatin A (TSA) but recovered upon extended induction period. These results also support the concept that the architectural role of these proteins can contribute to the preinitiation complex assembly required for basal transcription, but to a much lesser extent to the poised promoter scaffolding characteristic of activated transcription.

Full frame distilled prediction

Teacher imitation

Not 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.
