| dc.description.abstract | Los gliomas se encuentran entre los cánceres cerebrales más agresivos, y comprender por qué se vuelven resistentes al tratamiento sigue siendo un gran desafío en neurooncología. Herramientas tradicionales como el Análisis de Expresión Génica Diferencial (DGEA) han ayudado a identificar genes inusualmente activos o inactivos presentes en los tumores. Sin embargo, estos métodos a menudo se basan en modelos lineales simplistas cuando los genes funcionan en redes altamente interconectadas, que a menudo se influyen mutuamente de manera compleja. Esto dificulta distinguir entre las señales causales y los efectos posteriores de la enfermedad. Para superar estas limitaciones, necesitamos herramientas más inteligentes que capturen la estructura no lineal de la expresión génica. | spa |
| dc.description.abstractenglish | Gliomas are among the most aggressive brain cancers, and understanding why they become resistant to treatment remains a big challenge in neuro-oncology. Traditional tools like Differential Gene Expression Analysis (DGEA) have helped identify unusually active or inactive genes that are present in tumors. However, these methods often rely on simplistic, linear models when genes function in highly interconnected networks, often influencing each other in complex ways. This makes it hard to distinguish between causal signals and downstream effects of the disease. To go beyond these limitations, we require smarter tools to capture nonlinear structure of gene expression. | spa |
