Hepatocellular neoplasms with loss of liver fatty acid binding protein: Clinicopathologic features and molecular profiling.

HNF1A-inactivated hepatocellular adenomas (H-HCA) show steatosis, no atypia and loss of liver fatty acid binding protein (LFABP). LFABP loss also occurs in hepatocellular carcinoma (HCC). This study examines 68 LFABP-negative tumors: 33 typical H-HCA, 10 atypical hepatocellular neoplasms (AHN), 7 well-differentiated (WD) HCC, 18 moderately or poorly differentiated (MD/PD) HCC.

Multi-faceted epigenetic dysregulation of gene expression promotes esophageal squamous cell carcinoma.

Epigenetic landscapes can shape physiologic and disease phenotypes. We used integrative, high resolution multi-omics methods to delineate the methylome landscape and characterize the oncogenic drivers of esophageal squamous cell carcinoma (ESCC). We found 98% of CpGs are hypomethylated across the ESCC genome.

Development of an orthotopic model of invasive pancreatic cancer in an immunocompetent murine host.

Purpose: The most common preclinical models of pancreatic adenocarcinoma utilize human cells or tissues that are xenografted into immunodeficient hosts. Several immunocompetent, genetically engineered mouse models of pancreatic cancer exist; however, tumor latency and disease progression in these models are highly variable. We sought to develop an immunocompetent, orthotopic mouse model of pancreatic cancer with rapid and predictable growth kinetics.
