BACKGROUND Pancreatic cancer is one of the deadliest of all human malignancies with limited options for therapy. Here, we report the development of an optimized targeted drug delivery system to inhibit advanced stage pancreatic tumor growth in an orthotopic mouse model. METHODPRINCIPAL FINDINGS: Targeting specificity in vitro was confirmed by preincubation of the pancreatic cancer cells with C2...

Carcinomas of an epithelial-origin account for the majority of all malignant cancers worldwide. As the most common pancreatic cancer, Pancreatic Ductal Adeno Carcinoma (PDAC) is a carcinoma with an extremely high lethality [1-3]. Compared to other cancers originating in the digestive system, the therapeutic outcome of PDAC treatment is the least promising, largely resulting from a lack of sympt...

Endoglin, a 180-kDa disulfide-linked homodimeric transmembrane receptor protein mostly expressed in tumor-associated endothelial cells, is an endogenous binding partner of GAIP-interacting protein, C terminus (GIPC). Endoglin functions as a coreceptor of TβRII that binds TGFβ and is important for vascular development, and consequently has become a compelling target for antiangiogenic therapies....

Pancreatic ductal adenocarcinoma (PDA) shows a rich stroma where cancer-associated fibroblasts (CAFs) represent the major cell type. CAFs are master secretors of proteins with pro-tumor features. CAF targeting remains a promising challenge for PDA, a devastating disease where treatments focusing on cancer cells have failed. We previously introduced a novel pharmacological CAF-targeting approach...

This study was aimed to investigate miR-216a expression in pancreatic cancer and determine its effects on proliferation. miR-216a was found downregulated in pancreatic cancer tissues as compared to benign pancreatic lesions. JAK2 was identified as a miR-216a gene target. Further, in vivo treatment of PANC-1 tumors with miR-216a reduced JAK2 protein levels in the tumor and reduced tumor volume. ...

Activating K-RAS mutations occur at a frequency of 90% in pancreatic cancer, and to date no therapies exist targeting this oncogene. K-RAS signals via downstream effector pathways such as the MAPK and the PI3K signaling pathways, and much effort has been focused on developing drugs targeting components of these pathways. To better understand the requirements for K-RAS and its downstream signali...

PURPOSE Here, we describe a novel interplay between NAD synthesis and degradation involved in pancreatic tumor growth. EXPERIMENTAL DESIGN We used human pancreatic cancer cells, both in vitro (cell culture experiments) and in vivo (xenograft experiments), to demonstrate the role of NAD synthesis and degradation in tumor cell metabolism and growth. RESULTS We demonstrated that pharmacologic ...

To identify novel targets in pancreatic cancer cells, we used high-throughput RNAi (HT-RNAi) to select genes that, when silenced, would decrease viability of pancreatic cancer cells. The HT-RNAi screen involved reverse transfecting the pancreatic cancer cell line BxPC3 with a siRNA library targeting 572 kinases. From replicate screens, approximately 32 kinases were designated as hits, of which ...
