Abstract

fetched live from OpenAlex

Introdução: O Câncer de Bexiga (CaB) é responsável por 330 mil novos casos por ano, sendo que 130 mil evoluíram para óbito. Os tipos mais comuns de CaB são: os carcinomas uroteliais e os carcinomas de células transicionais, representando cerca de 95%. Os microRNA´s, por sua vez, são pequenas moléculas endógenas reguladoras de expressão gênica. Esses, frente a tumores, são divididos em miR´s supressores tumorais (inibem a carcinogênese) ou oncomiR´s (estimula a carcinogênese). O miR-10a (localização cromossômica 17q21.32) pode se comportar como um miR supressor de tumor, ou seja, sua subexpressão pode contribuir para a carcinogênese. Analisar o potencial biomarcador do miR-10a frente ao CaB, seguindo uma análise casuística do TCGA (The Cancer Genome Atlas) no pipeline de bioinformática CancerMirNome, frisando ainda os aspectos da relação desse miR com a sobrevida do paciente e sua capacidade diagnóstica de detecção do tipo tumoral em questão. Procedeu-se com a coleta de dados que relacionavam o miR-10a com o CaB na plataforma CancerMirNome. A partir disso foram obtidos os gráficos de PAN-CANCER (que compara a expressão desse miR no CaB e em outros tumores), Curva ROC (para determinar precisão diagnóstica), Curva Kaplan-Meier (para evidenciar a relação do miR com o bom ou mau prognóstico do paciente) e o gráfico de expressão diferencial (que relaciona a expressão do miR em um tecido normal versus tecido tumoral). O gráfico de PAN-CANCER evidenciou que alguns tipos tumorais (a exemplo do Adenocarcinoma de Cólon, Adenocarcinoma de Reto, Mesotelioma e Carcinossarcoma uterino) possuem diferenças significativas na expressão diferencial do miR-10a em tecidos normais e tumorais, em detrimento do CaB, que não apresenta mudança de expressão relevante.

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.
