Project description:To predict differentially expressed miRNAs between monosomy 3 and disomy 3, and to associate these miRNAs with the clinico-pathological parameters in South Asian Indian population with uveal melanoma (UM). The study consists of six uveal melanoma primary tumour tissues of South Asian-Indian population. These six tumours have been screened for chromosome 3 aberration using Chromogenic in-situ hybridisation (CISH). Thus, sample under the study includes, three each of monosomy 3 and disomy 3. The miRNA profiling was carried out from the tumor sections of formalin-fixed paraffin embedded eyeball samples. miRNA expression profile was obtained in monosomy 3 and disomy 3 samples, analysed by unsupervised analysis (Principal Component Analysis) and supervised analysis (Significance analysis of microarray). The select up-regulated and candidate miRNAs associated with monosomy 3 uveal melanoma tumors were validated further with qRT-PCR (n=86). Thus, this study indicates the role of miRNAs in UM tumor progression and their implication in predetermining the liver metastasis.

Project description:This study examined the genes under the control of FlhDC and sigmaF in E. coli. Keywords: wild-type, deletion and overexepression strains Under defined steady-state growth condition, we used two different genetic approaches to alter the modulator concentration in cells; (1) moderately expressing FlhDC or sigmaF from anhydrotetracycline (aTc) inducible and Tet repressor-controlled PLtet promoter in a plasmid-borne flhDC or fliA gene; (2) disrupting the expression of FlhDC or sigmaF in flhDC or fliA deletion mutant strains. Samples were taken from culture with wild-type or deletion strains at mid log phase (OD=0.2) or from overexpression strains at mid log phase (OD=0.2) before or 5 minutes after moderate induction. Samples were then RNA-stabilized using Qiagen RNAProtect Bacterial Reagent (Qiagen). Total RNA was then isolated using MasterPure kits (Epicentre Technologies). Purified RNA was reverse-transcribed to cDNA, labeled and hybridized to Affymetrix GeneChip E. coli Antisense Genome Arrays as recommended in the technical manual (www.affymetrix.com).

Project description:MicroRNAs are important regulators of cell-autonomous gene expression that influences many biological processes. They are also released from cells and are present in virtually all body fluids, including blood, urine, saliva, sweat, and milk. The functional role of extracellular miRNAs is controversial, and irrefutable demonstration of miRNA uptake by cells and canonical miRNA function is still lacking. Here we show that miRNAs are present at high levels in milk of lactating mice. To investigate intestinal uptake of miRNAs in newborn mice, we employed genetic models in which newborn miR-375 and miR-200c KO mice received milk from wildtype foster mothers. Analysis of intestinal epithelium, blood, liver and spleen revealed no evidence for miRNA uptake. miR-375 levels in hepatocytes were at the limit of detection and remained orders of magnitude below the threshold for target gene regulation (between 1000 and 10,000 copies/cell). Furthermore, our study revealed rapid degradation of milk miRNAs in the intestinal fluid. Together, our results indicate a nutritional rather than gene regulatory role of miRNAs in milk of newborn mice.

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goal of this study is genome wide association mapping for cold tolerance and yield studies in tomato (Solanum spp.) by phenotyping the genotypes under six diffrent temporal arrangments. Also for conducting quantitative reverse transcription polymerase chain reaction (qRT–PCR) assay of cold tolerant genes.
