Description

ER17p is a synthetic peptide corresponding to the sequence P295LMIKRSKKNSLALSLT311 of the estrogen receptor alpha (ER) and initially synthesized to mimic its calmodulin binding site. ER17p was subsequently found to elicit estrogenic responses in E2-deprived ER-positive breast cancer cells, increasing proliferation and E2-dependent gene transcription. Surprisingly, in E2-supplemented media, ER17p induced apoptosis and modified the actin network, influencing thereby cell motility. Here, we report that ER17p induces a massive early (3h) transcriptional activity in breast cancer cell lines SKBR3). Remarkably, about 75% of the significantly modified transcripts were also modified by E2, confirming the pro-estrogenic profile of ER17p. The different ER spectra of the used cell lines allowed us to extract a specific ER17p signature related to ER and its variant ER36. With respect to ER, the peptide activates nuclear (cell cycle, cell proliferation, nucleic acid and protein synthesis) and extranuclear signaling pathways. In contrast, through ER36 it exerts inhibitory events on inflammation and cell cycle and inhibition of EGFR signaling. This is the first work reporting ER36 specific transcriptional effects. The fact that a number ER17p-induced transcripts is different from those activated by E2 revealed that the apoptosis and actin modifying effects of ER17p are independent from the ER-related actions of the peptide.

Expression data from mouse intestine: C57Bl/6 MTHFR+/- vs BALB/c MTHFR+/-
  • organism-icon Mus musculus
  • sample-icon 8 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Gene 1.0 ST Array (mogene10st)

Description

Previous studies in our laboratory have shown that low folate diet (control diet with 2mg folate/kg, low folate diet with 0.3mg folate/kg) can induce intestinal tumors in BALB/c mice. In addition, we reported that C57Bl/6J mice did not form tumors under the same conditions.

Description

We exposed wild-type Vibrio cholerae E7496, multiple Vibrio cholerae virulence factor deleted genes with intact hemolysin A gene [CVD109] and without hemolysin A gene [CVD110] in E7946, and E.coli OP50 to wild-type C.elegans N2 for 18 hours. We used microarrays to detail the global gene expression and identified distinct classes of up-regulated and down-regulated genes during this process.

Gene expression pattern of skin biopsies of epidermolysis bullosa simplex patients in comparison with control subjects
  • organism-icon Homo sapiens
  • sample-icon 12 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Gene 1.0 ST Array (hugene10st)

Description

Tha altered biological pathways in Epidermolysis bulloda simplex, a rare monogenetic skin disease, have not been well characterized. Thus, the goal of this study is to characterize the expression profile of EBS patients compared with normal subjects using genomic expression analyses. Microarray analyses were performed with RNA isolated from skin biopsies. Robust multiarray analysis (RMA) normalization and Smyths moderated t test were used to select differentially expressed genes. Expression profiling comparisons show that 28 genes are differentially expressed in EBS patients compared to control subjects and 41 genes in EBS-DM compared to their matched controls. Nine genes involved in fatty acid metabolism and 2 genes in epidermal keratinisation are common altered expressed genes between the two subgroups. These two biological pathways contribute both to the formation of the cell envelope barrier and seem to be defective in the severe EBS phenotype. This study demonstrates, for the first time, the relevance of metabolic cluster, specifically fatty acid metabolism in EBS biology. Difference of expression for three (AWAT2, ELOVL , and SPRR4 ) of the five selected genes were validated using real-time reverse transcriptionpolymerase chain reaction. To our knowledge, the distinctive pattern of gene expression that characterizes EBS versus healthy skin tissue has never been reported.
