Hydrocephalus in the H-Tx rat: a monogenic disease?

The H-Tx rat is a genetic model of hydrocephalus for which thereis a poor understanding of the mode of inheritance.Previous studies suggested a polygenicmode of inheritance but the breeding data to supportthis hypothesis have not been reported. In an attempt to clarify the hereditary mode we have analyzed the data from eight generations of H-Tx rats and four generations of cross-matings between H-Tx rats and Sprague-Dawley (SD) rats. In the H-Tx rat colony 113 of 129 random brother-sister matings (87.60%) produced hydrocephalic offspring, with males and females being equally affected. The overall incidence varied greatly with an average of 30. 35%. In matings with more than three litters, all mating pairs yielded hydrocephalic pups. In cross-matings both hydrocephalic and normal H-Tx rats were mated with normal SD rats. No hydrocephalus was observed in the first generation of 124 pups (F1). Subsequent brother-sister matings of F1 animals generated hydrocephalic pups in the F2 generation with a lower incidence (4.67% in hydrocephalic HTx/SD matings and 5.11% in normal HTx/SD matings, respectively) than in the H-Tx rat colony (30.35%). Back-cross-matings between F2 rats and normal H-Tx rats yielded an incidence of hydrocephalus higher than that of the cross-matings but lower than that of the H-Tx colony. These data strongly suggest that the H-Tx rat is a homozygous carrier of an autosomal recessive hydrocephalus gene with incomplete penetrance. Furthermore, the data clearly rule out sex-linked and polygenic modes of inheritance and provide further insight with respect to genetic inheritance of hydrocephalus.

Selenium substituted axitinib reduces axitinib side effects and maintains its anti-renal tumor activity

Axitinib is a potent vascular endothelial growth factor receptor (VEGFR) inhibitor, which has a strong inhibitory effect on the three isoforms of VEGFR 1–3. Having strong therapeutic efficacy, its broad use is limited by its side effects such as hypertension, proteinuria, cardiovascular damage, and liver and kidney dysfunction. Selenium compounds are broadly reported to have a good protective effect on cardiovascular disease, inflammation, infection, and immune function. In this study, a selenium substitute of axitinib was synthesized, and its anti-renal cell carcinoma activity and side effects were investigated. The results of the study indicated that Se-axitinib had potent antitumor activity on renal cell carcinoma (RCC), alleviated vascular hyperpermeability, and also alleviated axitinib-related side effects including hypertension, liver dysfunction and kidney dysfunction significantly. Therefore, we suggest that Se-axitinib could be a solution to the severe side effects of VEGFR inhibitors and provide evidence to improve the outcome of RCC treatment.

Se-axitinib is a selenium substitution of sulfur in axitinib, which reduced the side effect of VEGFR inhibitors and maintained the potent anticancer activity of the original drug.     

Socioeconomic status,individual behaviors and risk for mental disorders: A Mendelian randomization study

BackgroundThere is increasing attention on the association of socioeconomic status and individual behaviors (SES/IB) with mental health. However, the impacts of SES/IB on mental disorders are still unclear. To provide evidence for establishing feasible strategies on disease screening and prevention, we implemented Mendelian randomization (MR) design to appraise causality between SES/IB and mental disorders.MethodsWe conducted a two-sample MR study to assess the causal effects of SES and IB (dietary habits, habitual physical activity, smoking behaviors, drinking behaviors, sleeping behaviors, leisure sedentary behaviors, risky behaviors, and reproductive behaviors) on three mental disorders, including bipolar disorder, major depressive disorder and schizophrenia. A series of filtering steps were taken to select eligible genetic instruments robustly associated with each of the traits. Inverse variance weighted was used for primary analysis, with alternative MR methods including MR-Egger, weighted median, and weighted mode estimate. Complementary methods were further used to detect pleiotropic bias.ResultsAfter Bonferroni correction and rigorous quality control, we identified that SES (educational attainment), smoking behaviors (smoking initiation, number of cigarettes per day), risky behaviors (adventurousness, number of sexual partners, automobile speeding propensity) and reproductive behavior (age at first birth) were causally associated with at least one of the mental disorders.ConclusionsMR study provides robust evidence that SES/IB play broad impacts on mental disorders.
