Comparison of anticancer effects of everolimus-gemcitabine combination with gemcitabine on pancreatic cancer using Rgs16 biomarker evaluation

This study showed that a combination of everolimus and gemcitabine is more potent than everolimus, which is more effective than gemcitabine, in killing pancreatic cancer cells. However,Rgs16 as a marker of invasion was very low in Panc-1 cells and the drugs were not effective in alteringRgs16 gene expression or protein level. Although this may suggest that Panc-1 is a very invasive cell line and these drugs are not effective in highly metastatic cases, the cell line might be resistant toRgs16 expression due to its specific mutations.

Jang Park Although there have been several analyses for identifying cancer-associated pathways, based on gene expression data, most of these are based on single pathway analyses, and thus do not consider correlations between pathways. In this paper, we propose a hierarchical structural component model for pathway analysis of gene expression data (HisCoM-PAGE), which accounts for the hierarchical structure of genes and pathways, as well as the correlations among pathways. Specifically, HisCoM-PAGE focuses on the survival phenotype and identifies its associated pathways. Moreover, its application to real biological ...

AbstractBackgroundPancreatic cancer induces parenchymal atrophy and duct dilation. The aim of this study was to evaluate whether these radiologic modifications are associated with outcomes.MethodsUpfront pancreaticoduodenectomy patients with available preoperative contrast enhanced CT scan imaging were retrospectively analyzed. Thickness of the pancreas, size of the main pancreatic duct (MPD), and distance of the tumor from the ampulla were assessed. A training cohort was selected, including short- (3 –12 months following surgery) and long-term (≥ 36 months) survivors. Identified survival determin...

RAS protein activator like 2 (RASAL2) belongs to the RAS GTPase-activating protein family and plays an important role in several cancers, including ovarian cancer, nasopharyngeal carcinoma, malignant astrocytoma, renal cell carcinoma, bladder cancer, colorectal cancer, liver cancer, triple-negative breast cancer, lung adenocarcinoma, and pancreatic ductal adenocarcinoma. Traditionally, RASAL2 has been regarded as a tumor suppressor but recent studies have found that it is an oncogene in specific types of cancer, such as colorectal cancer, liver cancer, triple-negative breast cancer, triple-negative/estrogen receptor-negati...

This study aimed to assess the impact of TGR in neuroendocrine tumors (NETs) and potential clinical and therapeutic applications.Materials and Methods.Patients (pts) with advanced grade (G) 1/2 NETs from the pancreas or small bowel initiating systemic treatment (ST) or watch and wait (WW) were eligible. Baseline and follow‐up scans were retrospectively reviewed to calculate TGR at pretreatment (TGR0), first follow‐up (TGRfirst), and 3(±1) months of study entry (TGR3m).Results.Out of 905 pts screened, 222 were eligible. Best TGRfirst (222 pts) cutoff was 0.8 (area under the curve, 0.74). When applied to TGR3m (10...
