Pubertally Initiated High-Fat Diet Promotes Mammary Tumorigenesis in Obesity-Prone FVB Mice Similarly to Obesity-Resistant BALB/c Mice.[Pubmed: 29024822]


Premenopausal breast cancer is associated with increased animal fat consumption among normal-weight but not overweight women. Our previous findings in obesity-resistant BALB/c mice showed that a diet high in saturated animal fat (HFD) promotes mammary tumorigenesis in both DMBA carcinogenesis and Trp53-null transplant models. Having made these observations in BALB/c mice, which have very modest HFD weight gain, we determined the effects of HFD in FVB mice, which gain significant weight on HFD. Three-week-old FVB mice fed a low-fat diet or HFD were subjected to 7,12-dimethylbenz[a]anthracene-induced carcinogenesis. Like BALB/c mice, HFD promoted mammary tumorigenesis. Development of tumors largely occurred prior to mice becoming obese, indicating the role of animal-derived HFD rather than resulting obesity in tumor promotion. Also similar to BALB/c mice, early-occurring adenosquamous mammary tumors were abundant among HFD-fed FVB mice. Tumors from HFD mice also had increased intra-tumor M2 macrophages. Prior to tumor development, HFD accelerated normal mammary gland development and increased mammary M2 macrophages, similarly to BALB/c mice. The promotional effects of puberty-initiated HFD on carcinogen-induced mammary cancer are thus largely weight gain-independent. Like BALB/c mice, HFD promoted adenosquamous tumors, suggesting a role for early age HFD in promoting this subtype of triple negative mammary cancer. M2 macrophage recruitment was common to both mouse strains. We speculate that a similar effect of HFD on immune function may contribute to epidemiological findings of increased breast cancer risk in young, premenopausal, normal-weight women who consume a diet high in saturated animal fat.

Comparative analysis of clinics, pathologies and immune responses in BALB/c and C57BL/6J mice infected with Streptobacillus moniliformis.[Pubmed: 29024796]


Streptobacillus (S.) moniliformis is a rat-associated zoonotic pathogen that occasionally causes disease in other species. We investigated the working hypothesis that intranasal infection might lead to different immune responses in C57BL/6 and BALB/c mice associated with distinct pathologies. This study confirmed with 75% mortality the known high susceptibility of C57BL/6 mice to S. moniliformis infection in comparison to BALB/c mice which did not develop signs of disease. Main pathologies in C57BL/6 mice were purulent to necrotizing lymphadenitis and pneumonia. Significant seroconversion was recorded in surviving mice of both strains. Differentiation of IgG-subclasses revealed mean ratios of IgG2b to IgG1 below 0.5 in sera of all mice prior to infection and of BALB/c mice post infection. In contrast, C57BL/6 mice had a mean IgG2b/IgG1 ratio of 2.5 post infection indicating a Th1 immune response in C57BL/6 versus a Th2 response in BALB/c mice. Evaluation of different sentinel systems revealed that cultural and serological investigations of these animals might not be sufficient to detect infection. In summary, an intranasal S. moniliformis infection model in C57BL/6 mice leading to purulent to necrotizing inflammations in the lung, the lymph nodes and other organs associated with a Th1 immune response is described.

Direct antiviral agents (DAAs) - a new age in the treatment of hepatitis C virus infection.[Pubmed: 29024739]


Hepatitis C virus (HCV) is a global health problem, because infection frequently leads to chronic hepatitis C eventually progressing to liver cirrhosis and liver cancer. Improved insights into the HCV replication cycle and the role of HCV non-structural proteins has recently enabled to identify drugs directly acting on specific HCV target structures. Agents from three drug classes have been developed and approved by the health authorities. Combinations of two or more drugs from different classes achieve high (>90%) HCV clearance rates and are well tolerated. This interferon-free DAA (direct antiviral agent) therapy has revolutionized antiviral therapy in hepatitis C so that successful hepatitis C treatment can be offered to virtually all patients irrespective of their co-morbidity. This review provides an overview over currently approved regimens and outlines their use in clinical practice. In addition potential short-comings of the current therapeutic options such as drug-drug interactions and selection of viral resistance are addressed. DAA combination therapy has the potential to obtain global control over hepatitis C. However, easy access to DAAs, availability of reliable HCV diagnostics, and affordable costs remain still important goals, which must be reached to globally eliminate hepatitis C.
