Project description:Series includes pooled (n = 5 mice per biological replicate) samples from lacrimal, meibomian, and submandibular glands of male palcebo- and testosterone-treated BALB/c mice. All experiments were run in triplicate (pooled biological replicates) on CodeLink Mouse Uniset I Microarrays. Keywords: repeat sample
Project description:Series includes pooled (n = 5 mice per biological replicate) samples from submandibular, sublingual, parotid, lacrimal, and meibomian glands of BALB/c mice. Both male and female samples were analyzed on CodeLink Mouse Uniset I Microarrays. Keywords: repeat sample
Project description:The mechanisms of chronic kidney disease-associated secondary hyperparathyroidism are partially understood. In this project we aimed to gain new information and propose research hypotheses by proteome and phosphoproteome profiling of normal and hyperplastic rat parathyroid glands. Glands were microdissected from rats on normal control diet or CKD-inducing high adenine diet enriched with phosphorus to produce secondary hyperparathyroidism. Protein extracts were pooled from 4 glands (2 rats) for proteome profiling (3 normal and 3 CKD pools), and from 12 glands (6 rats) for phosphoproteome profiling (2 normal and 2 CKD pools).
Project description:BACKGROUND. Coronavirus disease 2019 (COVID-19) is more benign in children compared with adults for unknown reasons. This contrasts with other respiratory viruses where disease manifestations are often more severe in children. We hypothesize that a more robust early innate immune response to SARS coronavirus 2 (SARS-CoV-2) protects against severe disease. METHODS. Clinical outcomes, SARS-CoV-2 viral copies, and cellular gene expression were compared in nasopharyngeal swabs obtained at the time of presentation to the emergency department from 12 children and 27 adults using bulk RNA sequencing and quantitative reverse-transcription PCR. Total protein, cytokines, and anti–SARS-CoV-2 IgG and IgA were quantified in nasal fluid. We used a subset of 21 samples for RNAseq analysis. RESULTS. SARS-CoV-2 copies, angiotensin-converting enzyme 2 (ACE2), and TMPRSS2 gene expression were similar in children and adults, but children displayed higher expression of genes associated with IFN signaling, NLRP3 inflammasome, and other innate pathways. Higher levels of IFN-α2, IFN-γ, IP-10, IL-8, and IL-1β protein were detected in nasal fluid in children versus adults. Children also expressed higher levels of genes associated with immune cells, whereas expression of those associated with epithelial cells did not differ in children versus adults. Anti–SARS-CoV-2 IgA and IgG were detected at similar levels in nasal fluid from both groups. None of the children required supplemental oxygen, whereas 7 adults did (P = 0.03); 4 adults died. CONCLUSION. These findings provide direct evidence of a more vigorous early mucosal immune response in children compared with adults and suggest that this contributes to favorable clinical outcomes.
Project description:Transcriptomic data was obtained from adults of the stink bug Nezara viridula to complement biochemical enzymatic activity analysis performed for digestive enzymes. Pooled reads from all sample types were used for de novo assembly of a reference transcriptome. After mapping reads to reference, differential expression was performed between the different tissues of the same diet or between the same tissue in different diets.
Project description:To investigate the gene expression differences between the normal peripheral zone glands compared to the moderatly and poorly differentiated tumor glands of the prostate. Laser microdissection of prostate cancer tissues to separate glands from stroma followed by RNA extraction from the glands and whole Genome Microarray. We have pooled normal glands from 10 patients, moderately differentiated tumor from 5 patients and poorly differentiated tumors from 4 patients with prostate carcinomas.
Project description:To elucidate the timing and mechanism of the clonal expansion of somatic mutations in cancer-associated genes in the normal endometrium, we conducted whole-exome and whole-genome sequencing for 56 endometrial glands and matched blood samples from 4 women. By collecting endometrial glands from different parts of the endometrium, we showed that multiple glands with the same somatic mutations occupied substantial areas of the endometrium.
Project description:Epithelial and especially mucosal immunity represents the first line of defence against the plethora of potential pathogens trying to invade via the gastrointestinal tract. The salivary glands of the fruit fly are an indispensable part of the gastrointestinal tract, but their contribution to the mucosal immunity has almost completely been neglected. Our major goal was to elucidate if the fly's salivary glands are able to mount an immune response and what the major characteristics of this immune response are.
