S. elongatus PCC 7942 Limited Proteolysis (LiP) Proteomics - Light vs Dark with Reduced/Non-reduced preparations in Dense Cultures

ABSTRACT: LiP experimental assays investigating structural alterations in Dense Light vs Dense Dark growth conditions with Reduced/Non-reduced preparations. Samples are Synechococcus elongatus PCC7942 cell lysates (BTO:0004304). Purpose: Probing light- and dark-induced conformational changes in dense cyanobacterial cultures using reduced and non-reduced sample preparation protocols. Technique: Limited proteolysis (LiP). Other details: Nonspecific protease used was pronase at an enzyme:substrate ratio of 1:200. The reduced samples were treated with 100 mM DTT prior to LiP. Data was searched with MaxQuant (using Label free quantification- Match between runs, LFQ-MBR).

A Functional Survey of Light-Responsive Genes Using A Rice NSF45K Microarray

Project description:We performed expression profiling experiments on two-week old rice leaf tissues grown in light and dark condition with the rice 47k array. Four biological replicates and a dye-swap were used. To generate more consistent results on light vs dark response in rice, biological replicates were prepared from 4 different varieties such as Kitaake, Nipponbare, Tapei309 and IR24 because individual genetic background can affect to expression profile (Townsend et al., 2003). Gene expression was assayed by probing the microarray with pooled Cy3 and Cy5 labeled cDNAs derived from 0.5-1.0ug high quality mRNA prepared from leaf samples. Keywords: Direct comparison

Peculiar proteome of dark-cultivated Euglena gracilis

Project description:Euglena gracilis is a flagellate photosynthetic microalga that, thanks to its metabolic adaptability, can grow under both autotrophic and heterotrophic conditions. We focused on the proteome of E. gracilis cultivated in Cramer-Myers medium in dark and light conditions. Cultures grown in the light showed a characteristic green coloration, while cultures incubated in the dark were bright, almost colorless, and had 60% fewer cells per volume. When cultured in the dark, microalga showed reduced concentration of chlorophylls (a, b, and total) and carotenoids compared to cells cultured in the light. Conversely, there was an increase in proline content in the dark compared to light cultivation. Phenol-extracted proteins were digested and purified using the SP3 protocol. We revealed 162 proteins, classified into 12 functional groups, which differentially accumulated in light- and dark-grown cells. The most represented categories in the case of dark cultivation were defense mechanisms, metabolism, and energy. Of note, in the category metabolism of lipids and sterols, we detected 4 proteins involved in the β-oxidation of fatty acids more abundant in the dark. Accumulation os stress- and detoxification-related proteins in microalgal cells cultivated in darkness supported interpretation of such condition as challenging stress factor. Euglena gracilis cultured in the dark is useful for basic research, applied biotechnology, and environmental protection.

mRNA Expression Data from Murine Hearts of Shiftwork MI, Normal MI and Sham Wildtype Mice at 24-hours Post-MI

Project description:Male C57Bl/6 mice were randomized to undergo 5 days of i) a shiftwork protocol (10-hour light: 10-hour dark cycle) before myocardial infarction (MI) surgery, ii) a normal 12-hour light: 12-hour dark environment before MI surgery, iii) a normal 12-hour light: 12-hour dark environment and used as sham controls, or iv) a shiftwork protocol (10-hour light: 10-hour dark cycle) and used as sham controls. MI surgery was performed on the 5th day, after which all mice were returned to a normal 12-hour light: 12-hour dark cycle. Hearts were collected 24-hours post-MI at ZT06. The microarray approach allows the investigation of transcriptome-wide gene expression changes in hearts from mice on a shiftwork cycle or on a regular light:dark cycle before MI.

Expression data from Magnaporthe oryzae (M. grisea) in response to darkness

Project description:The dark-phase in light/dark cycle plays an important role in successful disease development in M. oryzae-Oryza sativa. We used microarrays to detail the global programme of gene expression in response to light-to-dark transition. We identified different groups of genes (based on GO categories) that are up- or down-regulated in response to light-to-dark transition. Keywords: time course
