The "AMP KRAS
vaccine" administration and resulting immune response yields robust activation against all common mutations in the KRAS
protein compared to low or undetectable responses generated by soluble or benchmark treatments which fail to effectively reach the lymph nodes.
(25) The current expanded study population showed a similar mutation rate in each gene, AKT1 mutations in 5 specimens (0.4%), BRAF mutations in 78 specimens (6.5%), EGFR mutations in 226 specimens (19%), ERBB2 mutations in 17 specimens (1.3%), KRAS
mutations in 428 specimens (35%), NRAS mutations in 12 specimens (1.0%), and PIK3CA mutations in 47 specimens (3.9%).
has a zero-tolerance policy on corruption, he said.
The limit of detection for KRAS
mutations was evaluated by serially diluting cfDNA from the mutated pancreatic cancer cell line, CFPAC-1, producing a standard curve with a low-end fractional abundance of KRAS
mutations of 0.01%.
PIK3CA mutations were found in a total of five cases (Table 2), all of which showed KRAS
mutations as well.
This rare case of metastatic colorectal cancer with concomitant KRAS
and BRAF mutations had several unusual features including young age of presentation with no risk factors, harboring concomitant KRAS
and BRAF, and rapid progression of disease to death within 3 months of the onset of disease.
Kirsten rat sarcoma viral oncogene homolog (KRAS
) is involved in G-protein-mediated signal transduction.1
mutation occurs in 30%-50% of colorectal cancers.
is a signaling molecule -- a protein switch that triggers a cascade of molecular events that tell cells to grow and survive.

Introduction of the therascreen KRAS
test provides an FDA-approved diagnostic available for making treatment decisions for colorectal cancer patients.
Researchers have known that mutations in the Kras
gene are what cause pancreatic cancer to develop.
