The KRASG12R mutation displays uneven prevalence among cancers that harbor the highest occurrence of KRAS mutations: it is rare in lung and colorectal cancers (~1%), yet relatively common (~20%) in pancreatic ductal adenocarcinoma (PDAC), suggesting context-specific properties.
KRAS mutations and miRNA dysregulation (e.g. miR-21-5p oncomiR) play key roles in Pancreatic Ductal Adenocarcinoma (PDAC), leading to rapid progression of the disease.
IQ motif containing GTPase-activating protein 1 (IQGAP1) acts as a scaffold for aberrant mitogen-activated protein kinase (MAPK) signaling driven by KRAS mutations in pancreatic ductal adenocarcinoma (PDAC).
Pancreatic ductal adenocarcinoma (PDAC), like many KRAS-driven tumors, preferentially loses CDKN2A that encodes an endogenous CDK4/6 inhibitor to bypass the RB-mediated cell cycle suppression.
However, in pancreatic ductal adenocarcinoma (PDAC) there are only four abundantly common driver mutations (KRAS, CDKN2A, TP53, and SMAD4), which are not currently actionable.
KRAS is one of the most frequently mutated proto-oncogenes in pancreatic ductal adenocarcinoma (PDAC) and aberrantly activated in triple-negative breast cancer (TNBC).
Oncogenic KRAS mutation plays a key role in pancreatic ductal adenocarcinoma (PDAC) tumorigenesis with nearly 95% of PDAC harboring mutation-activated KRAS, which has been considered an undruggable target.
In the "CKP" mouse pancreatic ductal adenocarcinoma (PDAC) model driven by mutant K-Ras, Ctbp2 haploinsufficiency prolonged survival, abrogated peritoneal metastasis, and caused dramatic downregulation of c-Myc, a known critical dependency for TIC activity and tumor progression in PDAC.
In mice, a high-fat diet (HFD) and expression of oncogenic KRAS lead to development of invasive pancreatic ductal adenocarcinoma (PDAC) by unknown mechanisms.
In the context of pancreatic ductal adenocarcinoma (PDAC), oncogenic KRAS induces benign pancreatic intraepithelial neoplasias (PanINs), which exhibit features of oncogene-induced senescence.
Prediction of Recurrence With KRAS Mutational Burden Using Ultrasensitive Digital Polymerase Chain Reaction of Radial Resection Margin of Resected Pancreatic Ductal Adenocarcinoma.
Obesity driven by chronic consumption of high-fat diet (HFD) is a major risk factor for oncogenic KRAS-mediated pancreatic ductal adenocarcinoma (PDAC).
Pancreatic ductal adenocarcinoma (PDAC) is a dominantly (~95%) KRAS-mutant cancer that has extremely poor prognosis, in part this is due to its strong intrinsic resistance towards almost all therapeutic agents.
Activating <i>KRAS</i> mutations are found in nearly all cases of pancreatic ductal adenocarcinoma (PDAC), yet effective clinical targeting of oncogenic KRAS remains elusive.
Pancreatic ductal adenocarcinoma (PDAC) is characterized by KRAS- and autophagy-dependent tumorigenic growth, but the role of KRAS in supporting autophagy has not been established.
The MED-Amp assay successfully detected KRAS mutant ctDNA in 86% plasma samples obtained from patients with metastatic pancreatic ductal adenocarcinoma.
Based on experimental results, we have recently put forward a hypothesis that the coordination of CaM and PI3Kα with K-Ras4B forms a CaM-PI3Kα-K-Ras4B ternary complex, which leads to the formation of pancreatic ductal adenocarcinoma.
There remains intense interest in tractable approaches to target or silence the KRAS oncoprotein as a rational therapeutic strategy to attack pancreatic ductal adenocarcinoma (PDAC) and other cancers that overexpress it.
