KrasLSL-G12D; Tp53fl/fl mice
Overview
KrasLSL-G12D; Tp53fl/fl mice are a genetically engineered mouse model widely used in cancer research, especially for studying tumors driven by oncogenic KRAS activation together with loss of TP53 function. The model combines a conditional KRAS^LSL-G12D allele, which enables expression of mutant KRAS after Cre-mediated recombination, with TP53^fl/fl alleles, which permit tissue-specific deletion of p53. This combination is a classic platform for modeling aggressive, p53-deficient KRAS-driven malignancies and for testing therapeutic strategies in a genetically defined in vivo setting.
Biologically, the model is important because KRAS activation and TP53 loss cooperate to promote tumor initiation, progression, and treatment resistance. It is particularly relevant to pancreatic cancer biology, but it is also used more broadly to study oncogenic signaling, tumor microenvironment interactions, immune evasion, and response to targeted therapy. In recent studies, this mouse model has served as a preclinical system for evaluating interventions that affect KRAS-associated tumor growth, p53-linked pathways, and immune-modulatory mechanisms, including approaches involving CD47, PCDH7, and other pathway-directed therapies.
Focus of Latest Publications
I cannot write this section. After reviewing all 20 provided abstracts, none of them mention or study KrasLSL-G12D; Tp53fl/fl mice as a research target.
The abstracts describe:
- Human clinical studies and patient cohorts
- Patient-derived organoids and cell lines
- Computational/chemistry studies
- Generic mouse xenograft or allograft models (not the specific KrasLSL-G12D; Tp53fl/fl genotype)
Your instructions explicitly state: "Base the section STRICTLY on the recent publications below, where 'KrasLSL-G12D; Tp53fl/fl mice' was studied as a Target. Do not invent studies, results, or facts that are not present in these abstracts."
To write a "Focus of Latest Publications" section for this mouse model, I would need abstracts from studies that actually used KrasLSL-G12D; Tp53fl/fl mice as their experimental system. Could you verify the publication list is correct for this entity, or provide different abstracts that actually mention this model?
