The cooperation of the tumor suppressor gene Dlc1 and the oncogene Kras in tumorigenesis
Bibliographic record
Abstract
This thesis investigated the cooperation of the Kras2 oncogene with the tumor suppressor gene Dlc1 in lung tumor development. Dlc1 is a negative regulator of RhoGTPase proteins, which are mainly involved in the regulation of the actin cytoskeleton and cell migration. We hypothesized that loss of Dlc1 expression leads to more aggressive tumors, which should also result in increased incidence of metastasis. All experiments were performed in mice containing a heterozygous oncogenic Kras allele and a heterozygous gene trapped Dlc1 allele (KD) and in mice only carrying the oncogenic Kras allele (K+). Throughout all experiments we have consistently found no significant differences between the two groups in terms of tumor burden (tumor numbers, sizes and areas), metastases or methylation patterns. These results suggest that heterozygous downregulation of Dlc1 is not enough to increase tumor formation and metastasis development in the Kras lung tumors.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
