PURPOSE: Androgen deprivation therapy (ADT) is one of the main strategies to treat prostate cancer (PCa) at various stages of its development. Androgen receptor (AR) antagonists such as enzalutamide are mainstay treatments for castration-sensitive prostate cancer. Though, a majority of patients initially respond to ADT, most will eventually progress to castrate-resistant, due to the development of different mutations on the AR. PCa cells express high telomerase activity, and there is a correlation between the total activity of telomerase and the Gleason score...

PURPOSE: MicroRNAs (miRs) have been implicated in many aspects of tumor cell development and survival, including sensitivity to radiotherapy. In particular, miR-19a regulates the proliferation of cervical cancer cells, but its role in radiosensitivity is not known. Here, we describe the consequence of silencing miR-19a using antisense oligonucleotides (ASO) on the radiosensitivity of human cervical cancer SiHa cells. METHODS: Following transfection with miR-19a-ASO or control-ASO, SiHa cells were exposed to X-rays to determine their proliferation...

The underlying adaptive mechanisms by which insect strains are associated with specific plants are largely unknown. In this study, we investigated the role of herbivore-induced defenses in the host plant association of fall armyworm (Spodoptera frugiperda) strains. We tested the expression of herbivore-induced defense-related genes and the activity of plant-defensive proteins in maize and Bermuda grass upon feeding by fall armyworm strains. The rice strain caterpillars induced greater accumulation of proteinase inhibitors in maize than the corn strain caterpillars...

Risk assessment of infant using a realistic persistent organic pollutant (POP) exposure through breast milk is essential to devise future regulation of POPs. However, recent investigations have demonstrated that POP levels in breast milk collected from the same mother showed a wide range of variation daily and monthly. To estimate the appropriate sample size of breast milk from the same mother to obtain reliable POP concentrations, breast milk samples were collected from five mothers living in Japan from 2006 to 2012...

The neurotoxin MPTP has long been used to create a mouse model of Parkinson's disease (PD). Indeed, several MPTP analogues have been developed, including 2'-CH3-MPTP, which was shown to induce nigrostriatal DA neuronal depletion more potently than MPTP. However, no study on behavioral and molecular alterations in response to 2'-CH3-MPTP has been carried out so far. In the present work, 2'-CH3-MPTP was administered to mice (2.5, 5.0 and 10 mg/kg per injection, once a day, 5 days) and histological, biochemical, molecular and behavioral alterations were evaluated...

Preferential attention to living creatures is believed to be an intrinsic capacity of the visual system of several species, with perception of biological motion often studied and, in humans, it correlates with social cognitive performance. Although domestic dogs are exceptionally attentive to human social cues, it is unknown whether their sociability is associated with sensitivity to conspecific and heterospecific biological motion cues of different social relevance. We recorded video clips of point-light displays depicting a human or dog walking in either frontal or lateral view...

Recent quantitative analyses of human bone microanatomy, as well as theoretical models that propose bone microstructure and gross anatomical associations, have started to reveal insights into biological links that may facilitate remodeling processes. However, relationships between bone size and the underlying cortical bone histology remain largely unexplored. The goal of this study is to determine the extent to which static indicators of bone remodeling and vascularity, measured using histomorphometric techniques, relate to femoral midshaft cortical width and robusticity...

This study characterized patterns and correlates of parent-youth agreement on social anxiety in youth with and without autism spectrum disorder (ASD). Participants (279 verbally-fluent youth aged 8-16 years, NASD = 144, NTD = 135) completed the SASC-R. Youth with ASD exhibited higher social anxiety across informants. While TD youth endorsed higher anxiety than did parents, self- and parent-reports did not differ in youth with ASD. For children with ASD, higher parent-youth agreement was associated with lower lifetime ASD symptoms and higher adaptive skills...

Mechanical unloading induces disuse muscle atrophy and bone loss, but the details in mechanism involved in those pathophysiological conditions are not fully understood. Interaction between muscle and bone has been recently noted. Here, we investigated the roles of humoral factors linking muscle to bone during mechanical unloading using mice with hindlimb unloading (HU) and sciatic neurectomy (SNX). HU and SNX reduced muscle volume surrounding the tibia, tissue weights of soleus and gastrocnemius muscle, and trabecular bone mineral density (BMD) in the tibia of mice...
