Integrative array-based approach identifies MZB1 as a frequently methylated putative tumor-suppressor in hepatocellular carcinoma (expression)

Project description:Gene expression was profiled using a 4x44K Human Whole Genome Ver. 2.0 gene expression array (Agilent Technologies) according to the manufacturer's instructions (Microarray-based gene expression analysis protocol ver. 5.0.1, Agilent Technologies) Total RNAs extracted from Hep3B, HepG2, and HuH-7 cell lines and from these cell lines treated with 10 ?M 5-aza-dCyd for 5 days were used for conventional and pharmacological unmasking analyses, respectively. Total RNAs from two normal livers (C20 and C40) were used as controls.

Integrative array-based approach identifies MZB1 as a frequently methylated putative tumor-suppressor in hepatocellular carcinoma (MeDIP)

Project description:The analysis of DNA methylation profiles was performed by methylated DNA immunoprecipitation (MeDIP) using anti-5-methylcytidine antibody (Eurogentec, Seraing, Belgium) followed by the Human 244K Agilent CpG island microarray (Agilent, Santa Clara, CA) Genomic DNAs from Hep3B, HepG2 and HuH-7 cells were used for cancer samples and that from a normal liver tissue from surgical sample of colon cancer metastasis, as a control sample (C20)

Glycosylation Profiling of Neoplastic Biomarker Alpha Fetoprotein Through Intact Mass Protein Analysis

Project description:Alpha fetoprotein (AFP) is a circulating cancer biomarker implicated in multiple neoplastic malignancies, including hepatocellular carcinoma (HCC). AFP glycoforms with core fucosylation structure (AFP-L3) are used clinically as a biomarker, to predict risk of developing HCC and to monitor its recurrence. Mature AFP has a single glycosylation site, while there is a high degree of structural variation in AFP-glycan modifications. Because AFP has single glycosylation site, masses of intact AFP proteoforms can be used to differentiate and identify PTM in their native states. We developed a method for intact AFP glycoform analysis that utilizes AFP-specific immune-enrichment, followed by LC-high resolution mass spectrometry (LC-HRMS) analysis to differentiate and quantitate the relative abundance of AFP glycoforms and evaluated the method’s performance.

Transcription profiling by array of rice plants following cold treatment

Project description:Wild-type rice plants (O. sativa L. cv. Nipponbare) were grown in plastic pots filled with nutrient soil for 2 weeks under flooded lowland conditions and a 12 h/12 h light/dark cycle (50 M-1 10 ?mol photons/m2/s) at 28M-0C (day) and 25M-0C (night). For cold treatment, two-week-old plants were transferred from 28M-0C to 10M-0C and incubated for 1 day.

Transcription profiling by array of NaCl treated Oryza sativa wild type and OsTZF1-OX plants

Project description:Vector control and OsTZF1-OX rice plants (O. sativa L. cv. Nipponbare) were grown in plastic pots filled with nutrient soil for 2 weeks under flooded lowland conditions and a 12 h/12 h light/dark cycle (1000 umol photons/m2/s) at 28C (day) and 25C (night). For NaCl treatment, two-week-old plants were transferred to 250 mM NaCl solution and incubated for 2 days under the above conditions.

microRNA-expression profile in a series of Nodal marginal zone lymphoma patients [miRNA expression]

Project description:Nodal marginal zone lymphoma (NMZL) is a small B cell neoplasm whose molecular pathogenesis is still essentially unknown and whose differentiation from other small B cell lymphomas is hampered by the lack of specific markers. We have analyzed gene expression, miRNA profile and copy number data from 15 NMZLs. For comparison, 16 follicular lymphomas, 9 extranodal marginal zone lymphomas, 8 reactive lymph nodes and B cell subtypes were included. The results were validated by qRT-PCR in an independent paraffin-embedded series including 61 NMZLs. NMZL signature showed an enriched expression of gene sets identifying interleukins, integrins, CD40, PI3K, NFkB and TGF-Beta; and included genes expressed by normal marginal zone cells and memory B cells. The most highly overexpressed genes were SYK, TACI, CD74, CD82 and CDC42EP5. Genes linked to G2/M and germinal center were downregulated. Comparison of the gene expression profiles of NMZL and FL showed enriched expression of CHIT1 and TACI in NMZL, and BCL6, LMO2 and CD10 in FL. NMZL displayed increased expression of miR-223 and let-7f, while FL strongly expressed miR-494. Our study identifies new candidate diagnostic molecules for NMZL and reveals survival pathways activated in NMZL. microRNA-expression profiling was conducted in a series of 40 B-cell non-Hodgkin lymphoma patients (NMZL, and FL). Six lymph nodes with reactive lymphoid hyperplasia (RLN) were used as controls

grf7-1

Project description:Arabidopsis thaliana (L.) Heynh. ecotype Columbia was used in this study. Seeds were sterilized and stratified at 4 C for 2 days in the dark, sown, and grown on germination media (GM) agar plates in a growth chamber with 16 hours of fluorescent light at 40M-110 ?mol m-2 sec-1, 22 C, and 70% relative humidity.<br><br> The T-DNA insertion line for GRF7 was obtained from the ABRC (Stock No. CS878963;? Sessions et al., 2002). The T-DNA insertion was confirmed by amplifying the LB-flanking region in genomic DNA of individual candidate lines.
