DOI: 10.1016/j.celrep.2016.12.059
Abstract: Lung cancers exhibit pronounced functional heterogeneity, confounding precision medicine. We studied how the cell of origin contributes to phenotypic heterogeneity following conditional expression of KrasG12D and loss of Lkb1 (Kras;Lkb1). Using progenitor cell-type-restricted adenoviral Cre… read more here.

DOI: 10.1038/s41467-025-57297-5
Abstract: Harnessing the power of immune system to treat cancer has become a core clinical approach. However, rewiring of intrinsic circuitry by genomic alterations enables tumor cells to escape immune surveillance, leading to therapeutic failure. Uncovering… read more here.
