Abstract
Abstract Triple negative breast cancer (TNBC) has a poor prognosis due to its aggressive nature, high incidence of distant metastasis, and lack of targets for effective therapy. Therefore, a novel multifunctional biopolymer‐anticancer drug combination nanomedicine is designed for the prevention of spontaneous metastasis while treating primary TNBC. Oligomeric hyaluronic acid (oHA) and doxorubicin (DOX) at a synergistic ratio against TNBC cells are co‐loaded in a polymer‐lipid hybrid nanoparticle (PLN) which is then functionalized with an internalizing cyclic peptide iRGD (iRGD‐DOX‐oHA‐PLN). iRGD conjugation enhances cellular uptake and cytotoxicity in vitro and nanoparticle (NP) accumulation in human TNBC tumors that overexpress integrins. NP‐delivered oHA inhibits cell migration and invasion in vitro via the intracellular release of oHA that interacts with the receptor for hyaluronan mediated motility and downregulates the phospho‐extracellular signal‐regulated kinase (p‐ERK) signaling pathway. Intravenously injected iRGD‐DOX‐oHA‐PLN significantly inhibits the growth of primary TNBC tumors in a mouse model and prevents spontaneous metastasis to the lungs and lymph nodes, superior to free solutions of DOX, oHA, or both and NP formulations loaded with DOX or oHA. These results suggest that iRGD‐DOX‐oHA‐PLN can be a promising bioactive polymer‐drug combination nanomedicine for the treatment of TNBC and prevention of its spontaneous metastasis.

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 it
