BACKGROUND: Statins can reduce reproductive damage induced by obesity or high-fat diet (HFD), but the specific regulatory mechanisms are largely unknown. Since mTOR/p70s6k sinaling promotes spermatogonia proliferation and spermatogenesis, we hypothesized that this pathway will be involved in the protective effects of statin in HFD-induced reproductive dysfunction. METHODS: Male Sprague Dawley rats (3 weeks old) were randomly divided into a control group (standard diet), HFD group, and a fluvastatin group (HFD + fluvastatin at 6mg/kg, once daily by oral gavage)...

Autism spectrum disorder (ASD) remains unexplained and untreated despite the high attention of research in recent years. Aside from its various characteristics is the baffling male preponderance over the female population. Using a validated animal model of ASD which is the telomerase reverse transcriptase overexpressing mice (TERT-tg), we conducted ASD-related behavioral assessments and protein expression experiments to mark the difference between male and females of this animal model. After statistically analyzing the results, we found significant effects of TERT overexpression in sociability, social novelty preference, anxiety, nest building, and electroseizure threshold in the males but not their female littermates...

INTRODUCTION: Adiponectin is a pleiotropic adipocytokine with a strong inverse (protective) association with obesity, diabetes, and cardiovascular outcomes in stable patients. However, this relationship may be reversed in the setting of acute coronary syndrome (ACS). Given this possible complex relationship, we investigated adiponectin and cardiovascular (CV) outcomes in patients with diabetes and recent ACS. MATERIALS AND METHODS: We analyzed baseline adiponectin concentration and CV outcomes in 5,213 patients with type 2 diabetes enrolled 15-90 days (median 45 days) after ACS in the EXAMINE trial of alogliptin vs placebo...

Foxl2 is essential for mammalian ovary maintenance. Although sexually dimorphic expression of foxl2 was observed in many teleost, its role and regulative mechanism in fish remained largely unclear. In this study, we first identified two transcript variants of foxl2a and its homologous gene foxl2b in zebrafish, and revealed their specific expression in follicular layer cells in a sequential and divergent fashion during ovary differentiation, maturation and maintenance. Then, homozygous foxl2a mutants (foxl2a(-/-)) and foxl2b mutants (foxl2b(-/-)) were constructed, and detailed comparisons, such as sex ratio, gonadal histological structure, transcriptome profiling and dynamic expression of gonadal development-related genes, were carried out...

Deafferentation is accompanied by large-scale functional reorganization of maps in the primary sensory and motor areas of the hemisphere contralateral to injury. Animal models of deafferentation suggest a variety of cellular-level structural changes including depression of neuronal metabolism and even neuronal death. Whether similar neuronal changes contribute to patterns of reorganization within the contralateral sensorimotor cortex of chronic human amputees is uncertain. We used a functional MRI-guided proton magnetic resonance spectroscopy (1H-MRS) to test the hypothesis that unilateral deafferentation is associated with lower absolute levels of N-acetylaspartate (NAA, a putative marker of neuronal integrity) in the sensorimotor hand territory located contralateral to the missing hand in chronic amputees (N=19) as compared to the analogous hand territory of age/sex-matched healthy controls (N=28)...

Asparagus officinalis (garden asparagus) is a dioecious perennial crop. For agricultural production of A. officinalis, male plants have advantages over female plants. The dioecism of A. officinalis is determined by the single dominant masculinizing M locus, which is involved in tapetal cell development in stamens, but thus far no specific M locus genes have been identified. We re-analyzed previously published RNA-Seq data for the A. officinalis transcriptome, cloned some genes, and discovered that a putative ortholog of MYB35, which is indispensable for tapetal cell development in Arabidopsis thaliana, is absent in the genome of female plants in A...

BACKGROUND: Phenotypic changes in response to environmental influences can persist from one generation into the next. In many systems parental parasite experience influences offspring immune responses, known as transgenerational immune priming (TGIP). TGIP in vertebrates is mainly maternal and short-term, supporting the adaptive immune system of the offspring during its maturation. However, if fathers and offspring have a close physical connection, evolution of additional paternal immune priming can be adaptive...

Prenatal factors influence autism spectrum disorder (ASD) incidence in children and can increase ASD symptoms in offspring of animal models. These may include maternal immune activation (MIA) due to viral or bacterial infection during the first trimesters. Unfortunately, regardless of ASD etiology, existing drugs are poorly effective against core symptoms. For nearly a century a ketogenic diet (KD) has been used to treat seizures, and recent insights into mechanisms of ASD and a growing recognition that immune/inflammatory conditions exacerbate ASD risk has increased interest in KD as a treatment for ASD...
