Diethylnitrosamine induces lung adenocarcinoma in FVB/N mouse.

Background: Diethylnitrosamine is a well known carcinogen that induces cancers of various organs in mice and rats. Using FVB/N mouse strain, here we show that diethylnitrosamine induces primarily lung adenocarcinomas with modest tumor development in the liver, offering a new model to study chemical carcinogenesis in the lung.

Methods: Animals were exposed to a single high dose of diethylnitrosamine, and more than 70% of the mice developed lung cancer.

[Systemic mastocytosis with progressive disease course].

Authors report on a case of a male patient of systemic mastocytosis that was associated with extensive cutaneous lesions. Chronic diarrhoea worsening his quality of life was well managed by the administration of antihistamines. The pleural fluid recurrence soon after drainage has been controlled by the administration of alpha interferon.

Construction of a multiplex mutation hot spot PCR panel: the first step towards colorectal cancer genotyping on the GS Junior platform.

To support cancer therapy, development of low cost library preparation techniques for targeted next generation sequencing (NGS) is needed. In this study we designed and tested a PCR-based library preparation panel with limited target area for sequencing the top 12 somatic mutation hot spots in colorectal cancer on the GS Junior instrument. A multiplex PCR panel was designed to amplify regions of mutation hot spots in 12 selected genes ().

Quantitative and qualitative alterations of heparan sulfate in fibrogenic liver diseases and hepatocellular cancer.

Heparan sulfate (HS), due to its ability to interact with a multitude of HS-binding factors, is involved in a variety of physiological and pathological processes. Remarkably diverse fine structure of HS, shaped by non-exhaustive enzymatic modifications, influences the interaction of HS with its partners. Here we characterized the HS profile of normal human and rat liver, as well as alterations of HS related to liver fibrogenesis and carcinogenesis, by using sulfation-specific antibodies.
