Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
To characterize LICs in ALL irrespective of surface markers expression, we investigated leukemia initiating activities of cellular subfractions of patient-derived xenograft BCP-ALL cells sorted according to different cell cycle phases (i.e. G0/G1 and G2/M) followed by transplantation onto NOD/SCID mice. All cell fractions led to leukemia engraftment indicating LIC activity irrespective of cell cycle stage. Most importantly, cells isolated from G0/G1 cell cycle phases led to early leukemia engraftment in contrast to cells from late cell cycle (G2/M). To further characterize cells with different engraftment potential in vivo, we analyzed the gene expression profiles of early (G1b early) and late (G2/M) engrafting cells.

Description
Reprogramming of cancer cell metabolism toward aerobic glycolysis, i.e. the Warburg effect, is a hallmark of cancer; according to current views, the rationale for selecting such energy-inefficient metabolism is the need to increase cellular biomass to sustain production of daughter cells and proliferation. In this view, metabolic reprogramming is considered as a simple phenotypic endpoint that occurs as a consequence of signal transduction mechanisms, including oncogene-driven nutrient uptake and metabolic rewiring. A newly emerging paradigm is instead that transcriptional networks and oncogenic signaling can also be regulated downstream of metabolic pathways, that assume causative roles in controlling cancer cell behavior, above and beyond their core biochemical function. To explore possible links between glucose metabolism and nuclear gene transcription we compared immortalized mammary epithelial cells (MCF10A) and metastatic breast cancer cells (MDA-MB-231) growing in high glucose or in the presence of a widely used inhibitor of glucose uptake / glucose metabolism, 2-deoxy-glucose (2DG).

Description
Triple Negative Breast cancer accounts for some of the most aggressive types of breast cancer. By interrogating clinical datasets, we found that the activities of p63 and Hypoxia-Inducible-Factors (HIFs), two master regulators of the invasive and metastatic cancer cell phenotype are linked in TNBC through the p63-target Sharp1. Mechanistically, Sharp1 promotes HIF-1/HIF-2 proteasomal degradation by serving as HIFs presenting factor to the proteasome independently from oxygen levels and prior ubiquitination.

Description
YAP1 (Yes-associated protein 1) and TAZ (transcriptional coactivator with PDZ-binding motif, or WWTR1) are nucleo-cytoplasmic shuttling proteins that can function in the nucleus as transcriptional coactivators. Their role in regulating gene transcription has been so far mainly investigated by overexpressing YAP1 or TAZ, while here we sought to determine which genes are regulated by endogenous levels of YAP/TAZ. To this end, we compared MCF10A cells transfected with a control non-targeting siRNA to cells transfected with two independent mixes of siRNA targeting both YAP and TAZ.

Description
We performed RNA-seq and miRNA-seq in fetal RPE cells differentated during 5 weeks in a transwell set up Overall design: Samples from days 7, 14, 21, 28 and 35 were characterized. Cells were grown in a proliferation medium during the first week (EpiCM) and then in a maturation medium (MAM medium) that enahnces differentiation towards the desired phenotype.
