Project description:Atopic dermatitis (AD) and psoriasis vulgaris (PV) affect up to 3-5% of adults in developed countries and severely impair their quality of life thorough adulthood. MicroRNAs contribute to either the development or regulation of several diseases and are present in tissue. Although several miRNAs have been associated with AD or PV, to our knowledge, scarce studies have been published to date of miRNA profiling comparing AD and PV patients.
Project description:A huge number of microorganisms are colonized in human gut and the balance of their composition is closely related to human health. Recently, many probiotics such as bifidobacteria or lactobacilli have been introduced in our life as effective agents. However, we have not well understood their beneficial mechanisms including host-bacterial crosstalk. Accordingly, we took advantage of the protective mechanisms of probiotics against lethal infection of enterohemorrhagic Escherichia coli O157:H7 in murine gnotobiote model system
Project description:The MEK inhibitor selumetinib induces objective responses in children with neurofibromatosis type 1 (NF1) and inoperable plexiform neurofibromas (PNs). We conducted an open-label phase 2 study of selumetinib in 33 adults with PNs (NCT02407405). The objective response rate was 72.7% (24/33 patients). Median tumor volume decrease at best response was 23.6% at data cut-off with 19 patients continuing to receive study treatment. Acneiform rash was the most common adverse event (AE, 33/33 patients, 15 grade ≥2); acneiform rash and increases of ALT, AST, CPK, and lipase were the only grade 3/4 AEs to occur in more than 1 patient. Patients report improved pain levels and quality of life. Phosphorylation of ERK1/2 decreased significantly in paired biopsies (P≤0.0003) without compensatory phosphorylation of AKT1/2/3 (P =0.0697-0.9587). Selumetinib can induce sustained tumor volume decreases in adults with inoperable PNs and is well tolerated, while paired biopsies reveal novel pharmacodynamic insights. Kinase enrichment proteomic analysis was performed using patient pre-treatment/baseline and on-treatment specimens when sufficient material was obtained, with detectable on-target loss of binding of selumetinib targets MEK2 and MEK1 in treated samples.
Project description:FastQ files from 16S sequencing of fecal samples from pancreatic cancer xenografted mice not treated (CTRL) and treated with chemotherapy (GEM+nab-PTX), probiotics (PRO) and chemotherapy + probiotics (GEM+nab-PTX+PRO)
Project description:Research shows that children who are reared in households with low socioeconomic status are more vulnerable to heart disease, respiratory infection, and some cancers when they reach adulthood. This study conducted transcriptional profiling of PBMC in healthy adults who were low vs. high in early-life SES to explore the long-lasting genomic effects of early experience. Keywords: life stress, gene expression, inflammation, socioeconomic status Samples from 30 adults with low early-life SES and 30 adults with high early-life SES

Accordingly, we took advantage of the protective mechanisms of probiotics against lethal infection of enterohemorrhagic Escherichia coli O157:H7 in murine gnotobiote model system Germ free (GF) mice was used as control. E means O157-monoassociated mice. BAE means B. adolescentis and O157-associated mice. BLE means B. longum and O157-associated mice. Numbers indicate the days after O157 infection.
Project description:Although new treatments have improved survival for multiple myeloma (MM), quality of life remains poor for people with this incurable cancer. We conducted a multi-site randomized, waitlist-controlled trial of an individualized exercise program for people at all stages of MM (n=60). Compared to the waitlist control group, participants of the 12-week intervention had significant improvement in health-related quality of life, mediated through improved MM symptoms, cardiorespiratory fitness and bone pain, with were mostly maintained at follow-up (up to 12 months). Exploratory plasma metabolomics and lipidomics was conducted to delineate molecular mechanisms and biomarkers
Project description:Atopic dermatitis (AD) and psoriasis vulgaris (PV) affect up to 3-5% of adults in developed countries and severely impair their quality of life thorough adulthood. MicroRNAs contribute to either the development or regulation of several diseases and are present in body fluids, such as serum or plasma, where their identification is of remarkable value as minimally invasive circulating markers of disease. Although several miRNAs have been associated with AD, to our knowledge, no serum miRNA profiling of adult European AD patients has been published to date and no comparison of AD and PV has been performed.
Project description:Age-related hearing loss is a multifactorial and progressive process, which negatively impacts quality of life in many senior adults as the number one chronic neurodegenerative condition. This study was done to examine gene expression changes occurring in mouse auditory nerve and cochlear lateral wall tissues that may contribute to age-related hearing loss. In addition to conducting general differential expression analysis, a focused analysis of genes linked to neural cells was done.
Project description:Parkinson's disease (PD) is a chronic and progressive degenerative disease of the central nervous system. Degenerative neuropathy can occur in patients with PD even before typical clinical symptoms appear in the preclinical stage. Therefore, if the early diagnosis of degenerative diseases can be timely and the correlation with the disease progression can be explored, the disease progression will be slowed down and the quality of life of patients will be improved. In this study, the circRNA microarray was employed to screen the dysregulated circRNA in plasma samples of PD
