Description
Analysis of changes in gene expression levels after after prolonged exposure of triple-negative breast cancer cell lines to low doses of Panobinostat (LBH589), a pan-histone deacetylase inhibitor. Overall design: RNA-sequencing was performed after 96 hours and 4 weeks of incubation 10 nmol/L of LBH589 of two triple-negative breast cancer cell lines (HCC1806 and MDA-MB-231). All the expreiments were performed in biological triplicates

Affymetrix Poplar Genome Array (poplar)
Description
We studied the changes that occur in gene transcription during seasonal senescence in Populus trichocarpa pioneer leaves and fine roots. Plant senescence is a strictly regulated physiological process that allows relocating of valuable nutrients from senescent tissues before death. It might be induced by internal or external factors and among them, phytohormones play an undoubtedly significant role. Senescence was extensively studied in leaves, but the aging of other ephemeral organs, located underground, and its drivers are still poorly understood. We focused on collective results to fill in the knowledge gap about senescence of fine, absorptive roots and leaves in order to check if there are universal mechanisms involved during plant organ senescence. Transcriptional profiling was conducted with the use of microarrays to identify genes involved in developmental PCD. Samples were collected three times during a growth season. The first collection was considered as a control and was collected in early summer (July 7–15) when leaves and the root system were fully developed and functional. The second group of leaf and root samples were harvested in early autumn (October 1–7) when chlorophyll levels in leaves had decreased by approximately 40% and when fine roots had changed in color from white to brown. The third group of samples were harvested in the middle of autumn (November 2–9) when chlorophyll levels in leaves decreased by approximately 65% and fine roots were dark brown or black color. Our results reveal the important role of phytohormones in regulating the senescence of both studied organs. The transcriptomic analyses showed significant changes in gene expression that are associated with phytohormones, especially with ABA and jasmonates. We conclude that phytohormonal regulation of senescence in roots and leaves is organ-specific. In roots, phytohormones are involved indirectly in regulation of senescence by increasing tolerance for cold or resistance for pathogens, whereas such correlation was not observed in leaves.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
In this study we compared the effects of IL-2, IL-15, and IL-21 on the gene expression, activation of cell signaling pathways, and functional properties of cells derived from the CD4+ cutaneous T-cell lymphoma (CTCL). Whereas both IL-2 and IL-15 that signal through receptors that share the common gamma chain and the beta chain modulated the expression of >1,000 genes, IL-21 that signals via the receptor also containing gamma chain up-regulated <40 genes. All three cytokines induced tyrosine phosphorylation of Jak1 and Jak3. However, only IL-2 and IL-15 strongly activated STAT5, PI3K/Akt, and MEK/ERK signaling pathways. In contrast, IL-21 selectively activated STAT3. Whereas all three cytokines protected CTCL cells from apoptosis, only IL-2 and IL-15 promoted their proliferation. The effects of the cytokine stimulation were Jak3- and Jak1-kinase dependent. These findings document the vastly different impact of IL-2 and IL-15 vs. IL-21 on malignant CD4+ T cells. They also suggest two novel therapeutic approaches to CTCL and, possibly, other CD4+ T cell lymphomas: inhibition of the Jak1/Jak3 kinase complex and, given the known strong immunostimulatory properties of IL-21 on CD8+ T, NK, and B cells, application of this cytokine to boost an immune response against malignant CD4+ T cells.

Description
Melanoma is a highly aggressive cancer with increasing incidence rates and a poor survival, particularly in patients with AJCC stage IV and advanced stage III. Deregulation of NF-kB is linked to different pathological states, including melanoma. To identify the involvement of NF-kB pathway regulation in melanoma progression, we manipulated NF-kB pathway activation and profiled gene expression using RNA-sequencing. Overall design: mRNA profiles of IM-0223 cells overexpressing KPC1 (KPC1) or control (V0) generated by deep sequencing using Illumina HiSeq 2500.

Affymetrix Human Exon 1.0 ST Array [transcript (gene) version (huex10st)
Description
Melanoma is one of the most aggressive and treatment-resistant cancers. It represents the most life-threatening neoplasm of the skin, and its incidence has been increasing for the last three decades. Melanoma evolves from the local transformation of melanocytes to primary tumors, which can metastasize to multiple organs. Brain metastases represent one of the most significant causes of death in cutaneous melanoma patients. Despite aggressive multi-modality threapy, patients with melanoma brain metastasis have a median survival of less than a year, with a majority of these patients dying as a result of their intracranial disease. To identify alterations in gene expression related to brain metastasis, we used Affymetrix expression arrays to assess differentially expressed genes in melanocytes, lymph node metastases, and brain metastases.
