Description
Difference in RNA content of different cell types introduces bias to gene expression deconvolution methods. If ERCC spike-ins are introduced into samples, predicted proportions of deconvolution methods can be corrected Overall design: Two cell types of distinctly different sizes and RNA per cell content: HEK cells and Jurkat cells were mixed in different proportions ensuring that each mixture contained total of one million cells. We sequenced RNA of the samples (including ERCC spike-in controls to 382 be able to control for the absolute RNA-concentration).

Affymetrix C. elegans Genome Array (celegans)
Description
Bio-electrospray, the direct jet-based cell handling apporach, is able to handle a wide range of cells. Studies at the genomic, genetic, and the physiological level have shown that, post-treatment, cellular integrity is unperturbed and a high percentage (>70%, compared to control) of cells remain viable. Although, these results are impressive, it may be argued that cell based systems are oversimplistic. This study utilizing a well characterised multicellular model organism, the non-parasitic nematode Caenorhabditis elegans. Nematodes were subjected to bio-electrosprays to demonstrate that bio-electrosprays can be safely applied to nematodes.

Description
Recent research has highlighted that the polyphenols Quercetin (Q) and Tannic acid (TA) are capable of extending the lifespan of C. elegans. To gain a deep understanding of the underlying molecular genetics, we analyzed the global transcriptional patterns of nematodes exposed to Quercetin or Tannic acid concentrations that are non-effective (in lifespan extension), lifespan extending or toxic.

Meta-Analysis of Global Transcriptomics Suggests that Conserved Genetic Pathways are Responsible for Quercetin and Tannic Acid Mediated Longevity in C. elegans.

Description
Low concentrations of the dissolved leonardite humic acid HuminFeed (HF) prolonged the lifespan and enhanced the thermal stress resistance of the model organism Caenorhabditis elegans. Furthermore growth was impaired and reproduction delayed, effects which have also been identified in other polyphenolic monomers, including tannic acid, rosmarinic acid, and caffeic acid. Moreover, a chemical modification of HF (HF-HQ), which increases its phenolic/quinonoid moieties, magnified the biological impact on C. elegans. To gain a deep insight into the molecular basis of these effects, we performed global transcriptomics on young adult (3 d) and old adult (11 d) nematodes exposed to two concentrations of HF and young adults (3 d) exposed to two concentrations of HF-HQ.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Neoadjuvant chemotherapy has been shown to be equivalent to post-operative treatment for breast cancer, and allows for assessment of chemotherapy response. In a pilot trial of docetaxel (T) and capecitabine (X) neoadjuvant chemotherapy for Stage II/III BC, we assessed correlation between baseline gene expression and tumor response to treatment, and examined changes in gene expression associated with treatment. Patients received 4 cycles of TX. Tumor tissue obtained from Mammotome core biopsies pretreatment (BL) and post-Cycle 1 (C1) of TX was flash frozen and stored at -70C until processing. Gene expression analysis utilized Affymetrix HG-U133 Plus 2.0 GeneChip arrays. Statistical analysis was performed using BRB Array Tools after RMA normalization. Gene ontology (GO) pathway analysis used random variance t-tests with a significance level of p<0.005. For gene categories identified by GO pathway analysis as significant, expression levels of individual genes within those pathways were compared between classes using univariate t-tests; those genes with significance level of p<0.05 were reported.
