Mechanosensory hair cells (HCs) are the primary receptors of our senses of hearing and balance. However, very little is known about the transcriptional regulators involved in HC fate determination and differentiation. In this paper, we show that expression of three HC lineage-specific transcription factors: Gfi1, Pou4f3 and Atoh1, can induce a direct commitment towards HC fate during in vitro embryonic stem cell (ESC) differentiation. Induced HCs (iHCs) express numerous HC-specific genes and exhibit polarized membrane protusions reminiscent of stereociliary bundles.

View SamplesTo investigate the role of ADAR1 in gastric carcinogenesis, RNA sequencing and small RNA sequencing were performed in AGS and MKN-45 cells with stable ADAR1 knock-down. Changed frequencies of editing and messenger RNA (mRNA) and microRNA (miRNA) expression were then identified by bioinformatic analyses. Overall design: mRNA and miRNA sequencing were performed before and after stable knockdown of ADAR1 in AGS and MKN-45 cell line

View SamplesThe leaf extract of T. indica had been reported to posses high phenolic content and showed high antioxidant activities. However, scientific data on the molecular mechanisms underlying the beneficial properties of the leaf extract are still lacking. In this study, the effects of the leaf extract on the expression of genes in cultured HepG2 cells were investigated using microarray technology. The leaf extract significantly regulated the expression of genes involved with consequential impact on the coagulation system, cholesterol biosynthesis, xenobiotic metabolism signaling and antimicrobial response.

View SamplesLeptospirosis is a neglected zoonotic disease of global importance. Despite its prevalence, pathogenesis is still poorly understood. Our aim was to discover transcripts responsable for pathogenicity of leptospirosis. We compared the transcriptome profiles of saprophyte, attenuated and virulent strain of Leptospira spp.

View SamplesSevere fever with thrombocytopenia syndrome phlebovirus (SFTSV), listed in the WHO most dangerous pathogens, has 12-30% fatality rates with a characteristic thrombocytopenia syndrome. With a majority of clinically diagnosed SFTSV patients older than ~50 years, age is a critical risk factor for SFTSV morbidity and mortality. Here, we report an age-dependent ferret model of SFTSV infection and pathogenesis that fully recapitulates the clinical manifestations of human infections. While young adult ferrets (=2 years old) did not show any clinical symptoms and mortality, SFTSV-infected aged ferrets (=4 years old) demonstrated severe thrombocytopenia, reduced white blood cells, and high fever with 93% mortality rate. Moreover, significantly higher viral load was observed in aged ferrets. Transcriptome analysis of SFTSV-infected young ferrets revealed strong interferon-mediated anti-viral signaling, whereas inflammatory immune responses were markedly upregulated and persisted in aged ferrets. Thus, this immunocompetent age-dependent ferret model should be useful for anti-SFTSV therapy and vaccine development. Overall design: Two groups of young adults (20-24 months, =2Y) and aged ferrets (48-50 months), =4 Y) were inoculated via the IM route with 107.6 TCID50 of the SFTSV CB1/2014 strain. PBMCs were isolated at 2 and 4 dpi from each group of ferrets (n=3) by density gradient centrifugation using Ficoll-Paque Plus according to the manufacture's protocol.

View SamplesThere is an association between transcriptome and the exercise-related phenotype. Peripheral blood cells suffer alterations in the gene expression pattern in response to perturbations caused by exercise. The acute response to endurance activates stress and inflammation, as well as growth and tissue repair responses.
PBMCs express a transcriptome signature predictor of oxygen uptake responsiveness to endurance exercise training in men.
