The Hippo pathway is a central regulator of tissue development and homeostasis, and has been reported to have a role during vascular development. Here we develop a bioluminescence-based biosensor that monitors the activity of the Hippo core component LATS kinase. Using this biosensor and a library of small molecule kinase inhibitors, we perform a screen for kinases modulating LATS activity and identify VEGFR as an upstream regulator of the Hippo pathway. We find that VEGFR activation by VEGF triggers PI3K/MAPK signaling, which subsequently inhibits LATS and activates the Hippo effectors YAP and TAZ...

According to historical evidence, the abuse of opium has been reported all over the globe-specifically throughout Eastern nations-since the sixteenth century. Before that, opium had mostly been applied as medication. Reference has been made in traditional Persian medical literature to the method of cultivation, properties, side effects and toxicity. In sixteenth century Iran, during the reign of the Safavids, opium abuse began. It was from then that prominent Persian scholars started to think of solutions to this societal problem...

In vivo tumour models are essential for studying the biology of cancer, identifying tumour targets and evaluating anti-tumour drugs. Considering the request for the minimization of animal experiments and following the "3R"-rule ("replacement", "refinement", "reduction"), it has become crucial to develop alternative experimental models in cancer biology. Several studies have already described the avian chorioallantoic membrane (CAM) model as an alternative to rodents, suitable to investigate growth, progression and metastasis of various types of cancer...

Neurological diseases, including dementias such as Alzheimer's disease (AD) and fronto-temporal dementia (FTD) and degenerative motor neuron diseases such as amyotrophic lateral sclerosis (ALS), are responsible for an increasing fraction of worldwide fatalities. Researching these heterogeneous diseases requires models that endogenously express the full array of genetic and epigenetic factors which may influence disease development in both familial and sporadic patients. Here, we discuss the two primary methods of developing patient-derived neurons and glia to model neurodegenerative disease: reprogramming somatic cells into induced pluripotent stem cells (iPSCs), which are differentiated into neurons or glial cells, or directly converting (DC) somatic cells into neurons (iNeurons) or glial cells...

The objective of this study was to evaluate the effects of preweaning total plane of milk intake and weaning age on intake, growth performance, and blood metabolites of dairy calves. A total of 48 Holstein calves (40 ± 1.6 kg of body weight) were used in a 2 × 2 factorial arrangement with the factors of weaning age (d 60 vs. 75) and the total plane of milk intake (medium vs. high) during the preweaning period. Calves were assigned to 1 of 4 treatments: (1) calves fed medium plane of milk (MPM) intake and weaned on d 60 of age (MPM-60d, 4 L/d of milk from d 3 to 10, 6 L/d of milk from d 11 to 55, and 3 L/d of milk from d 56 to 60 of age; total milk intake = 317 L), (2) calves fed MPM intake and weaned on d 75 of age (MPM-75d, 4 L/d of milk from d 3 to 10 and 4...

OBJECTIVE: Trans-chalcone is a chalcone with hepatoprotective and anti-inflammatory effects. However, the mechanism of these positive effects, especially on miR-451 as an inflammatory regulator, is poorly understood. In this regard, this microRNA (miRNA) acts by inhibition of hepatic interleukin-8 (IL-8) production in the liver which is one of the main proinflammatory cytokines. Th is study for the first time examined the effect of trans-chalcone on miR-451/IL-8 pathway. METHODS: In present study, 21 male rats were randomly divided into 3 groups (n=7 per each group): control which received solvent (NS), groups 2 (N2T) and 3 (N6T), which received transchalcone for 2 and 6 weeks, respectively...

Echinococcus granulosus is a helminth from the family Taeniidae, which causes cystic echinococcosis (CE) in humans and diverse livestock around the world. The identification of existing genotypes in different regions is a major step towards the prevention and establishment of control programmes for the disease. This study aimed to detect CE genotypes using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) of the internal transcribed spacer-1 (ITS1) gene and sequencing of the cytochrome c oxidase subunit 1 (Cox1) gene in isolates from the central part of Mazandaran province, northern Iran...

Stem cells self-renew and differentiate to generate all tissues and cells in the body. Stem cell health promotes adaptive responses to tissue damage or loss and is essential for tissue regeneration with age. In the past decade, the evolutionarily conserved transcription factors FOXO with known functions in promoting healthy aging have emerged as key regulators of stem cell homeostasis in various tissues, including blood, neural, and muscle stem cells. Aberrant FOXO functions have been implicated in a variety of disorders including neurodegenerative, blood, cancer, and diabetes some of which are fostered by abnormal stem cell function...
