Project description:Coffee leaf miner is an important plague in coffee crops. Using subtracted cDNA libraries and nylon filter arrays, we analyzed the expression profile of 1536 expressed sequence tags (ESTs) of coffee plants from an hybrid progeny (C. arabica x C. racemosa), containg resistant (R) and susceptible plants (S) to the infestation of coffee leaf miner. Leaf discs were collected from non-infested plants (R control - RC; S control - SC), infested plants after moth oviposition (R oviposition - Ro; S oviposition - So) and infested after larvar eclosion (R eclosion - Re; S eclosion - Se).

Briefly, 7-week-old male C57BL/6J mice purchased from Charles River Laboratories Japan (Yokohama) were divided into the following five groups. The normal diet group (ND group) was fed D12450B (10 kcal% fat, Research Diets, New Brunswick, NJ, USA). The high-fat diet group (HF group) was fed D12492 (60 kcal% fat, Research Diets, New Brunswick, NJ, USA). The caffeinated coffee group (HFCC group) was fed a high-fat diet containing 2% caffeinated freeze-dried coffee. The decaffeinated coffee group (HFDC group) was fed a high-fat diet containing 2% decaffeinated freeze-dried coffee. The green unroasted coffee group (HFGC group) was fed a high-fat diet containing 2% unroasted caffeinated freeze-dried coffee. The mice had ad libitum access to their diets and drinking water. After 9 weeks, mice were sacrificed and the livers were subjected to the Affymrtix DNA microarray experiment.

Project description:Background: Understanding the genetic elements that contribute to key aspects of coffee biology will impact future agronomical improvements for this economically important tree. The past years, EST collections were generated in Coffee, opening the possibility to create new tools for functional genomics. Results: The project PUCE CAFE, set up by the scientific consortium NESTLE/IRD/CIRAD has developed of long oligonucleotide coffee array using public coffee EST sequences mainly obtained from different stages during fruit development and leaves in Coffea canephora (Robusta). We have performed a validation experiment in order to check the array usability and the reproducibility of hybridizations. Conclusion: We have generated the first 15K Coffee array during this three years project PUCE CAFE, granted by The French National Research Agency (ANR, Programme Génoplante) . This new tool was dedicated to large scale transcriptomic analysis during grain development of Coffea canephora grown in different countries . Furthermore, other analysis have been also initiated by the different partners like analysis of polyploidy or drought resistance. In any case, at the end of the project, the generated arrays will be available to the international scientific community.

Project description:Our experiments showed that long-term coffee or green tea(GTE) extract supplementation( from 3 months old to 12 months old) ameliorates age-related hearing loss (ARHL) in mice. Then we explored the possible underlying mechanisms through comparing the cochlear transcriptome profiling (RNA-seq) of the coffee or GTE treated mice to the control mice.

Project description:The intermediate seed category was defined in the early 1990s using coffee (Coffea arabica) as a model. In contrast to orthodox seeds, intermediate seeds cannot survive complete drying, which is a major constraint for seed storage, for both biodiversity conservation and agricultural purposes. However, intermediate seeds are considerably more tolerant to drying than recalcitrant seeds, which are highly sensitive to desiccation. To gain insight into the mechanisms governing such differences, changes in desiccation tolerance (DT), hormone content and the transcriptome were analysed in developing coffee seeds. Acquisition of DT coincided with a dramatic transcriptional switch characterised by the repression of primary metabolism, photosynthesis and respiration, and the upregulation of genes coding for late embryogenesis abundant (LEA) proteins, heat shock proteins (HSP) and antioxidant enzymes. Analysis of heat-stable proteome in the mature coffee seed confirmed the accumulation of LEA proteins identified at the transcript level. Transcriptome analysis also suggests a major role for ABA and for the transcription factors CaHSFA9, CaDREB2G, CaANAC029, CaPLATZ and CaDOG-like in DT acquisition. The ability of CaHSFA9 and CaDREB2G to trigger HSP gene transcription was validated by Agrobacterium-mediated transformation of coffee somatic embryos.

Project description:A summary of the work associated to these microarrays is the following: Background: Phenolic compounds present in coffee are antioxidants in vitro that might protect against cardiovascular disease and certain types of cancer in humans. Objective: Our aim was to identify differentially expressed genes upon incubation of HT-29 human colon cancer cells with instant caffeinated coffee (ICC) or caffeic acid (CA) using microarrays. Results: In HT-29 cells incubated with ICC, 77 genes were overexpressed whereas 162 were underexpressed. Upon incubation with CA, 12 genes were overexpressed whereas 33 were underexpressed. A list of five overexpressed genes and eleven underexpressed genes were found in common between the two conditions and was use to construct a biological association network. In the generated network, STAT5B and ATF-2 appeared as highly interconnected nodes. STAT5B overexpression was confirmed at the mRNA and protein levels. For ATF-2, the changes in mRNA levels were confirmed for both ICC and CA, whereas the decrease in protein levels was only observed in CA-treated cells. The levels of cyclin D1, a target gene for both STAT5B and ATF-2 transcription factors, decreased dramatically in breast cancer cells treated with CA or ICC. Conclusions: Coffee polyphenols are able to affect gene expression in cancer cells through the modulation of STA5B and ATF-2 transcription factors. The aim of our study was to evaluate, by using whole genome microarrays, the effects of one cup of coffee, either regular caffeinated coffee or a coffee polyphenol, such as caffeic acid, on HT-29 gene expression, Three experimental approaches were conducted to assess the effects of coffee on HT29 cells. I) Incubation with non cytotoxic concentrations of ICC (7 µg/mL) for 24h. (Group ICC); II) Incubation with non cytotoxic concentrations of CA (1.68 µg/mL) for 24h. (Group CA); III) non treatment of HT-29 to refered as a control (Group CNT). Triplicate samples were hybridized for each experimental condition (9 samples in total). The samples provided were analyzed using the specific software GeneSpring GX.
