Abstract

fetched live from OpenAlex

O câncer de mama triplo-negativo (TNBC) corresponde a 15–20% dos diagnósticos de câncer de mama e apresenta prognóstico desfavorável, principalmente em decorrência da ausência de alvos terapêuticos específicos e do desenvolvimento frequente de quimiorresistência. Este projeto propõe uma abordagem integrativa para identificar fármacos reposicionáveis capazes de reverter a resistência terapêutica em TNBC, combinando análises multiômicas computacionais e validação experimental. Serão analisados dados públicos de transcriptômica single-cell de pacientes submetidas à quimioterapia neoadjuvante para a definição de assinaturas moleculares associadas à resistência. Essas assinaturas serão exploradas para priorização de compostos por meio de connectivity mapping, análise de redes regulatórias e algoritmos de inteligência artificial e machine learning. Durante estágio de pesquisa na McGill University, serão aplicados métodos avançados de inferência de redes gênicas e análise de elementos regulatórios epigenéticos para elucidar os mecanismos transcricionais subjacentes à resistência e refinar a seleção dos candidatos terapêuticos. A validação experimental incluirá a geração de linhagens celulares resistentes in vitro, ensaios de eficácia e reversão de resistência, e validação em modelo singênico murino 4T1, com avaliação de eficácia antitumoral, impacto metastático e análises imunohistoquímicas. Espera-se identificar de três a cinco fármacos reposicionáveis com potencial sinérgico à quimioterapia e capacidade de modular os programas moleculares associados à quimiorresistência, contribuindo para o avanço de estratégias terapêuticas no TNBC.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
