Project description:To gain insight into the differential expressed genes in immune edited tumor cell lines, we performed genome-wide RNA-sequencing analysis (RNA-seq) in parental P0 (CaSki-P0) and immune edited P3 (CaSki-P3) cells.
Project description:The emergence of immune resistance variants during immunotherapy is poorly understood. We generated a highly immune resistant cell line (P3) from a susceptible cell line (P0) by subjecting it to 3 rounds of in vivo immune selection. Subsequently, microarray analysis of P0 and P3 was performed to identify genes that may contribute to the increase in immune resistance. Experiment Overall Design: Four experimental replicates were prepared for each cell line. P0 is the control cell line, and P3 is the experimental/resistant cell line.

Project description:Villar and intervillar epithelial cells were FACs isolated from P0, P3, P6, or P10 CD1 mouse medial small intestine. Three biological replicates were used for e ach population, and expression profiles were determined using Illumina HiSeq. Comparison of the sample groups allowed for identification of compartment-specific and stage-specific genes.
Project description:Investigation of differential gene expression array between primary and cultured human bone marrow MSCs as adherent cells (P0 and P3) or spheres (P0 and P3)
Project description:Our previous data obtained by using immunohistochemistry showed, that Fgf10+/- (50% Fgf10 expression compared to WT) in hyperoxic condition at postnatal day 3 (P3) compared to WT has less vessel count in the lung and less muscularization of small capillaries in the lung. Furthermore, Fgf10+/- showed a drastic increase in mortality upon hyperoxic lung injury. Main question to be answer by this experiment is as followed: Does Fgf10+/- mice after hyperoxia from P0-P3 show different expression profiles at P3 compared to WT? To adress this question we harvest lungs at P3 from WT and Fgf10+/- after hyperoxia treatment from P0-P3. For this the mice were sacrificed by Ketamin/ Dormitor ip, lungs were perfused transcardiac with PBS and directly frozen in liquid nitrogen.

Project description:Expression arrays comparing Campylobacter jejuni 11168 before and after serial passage in C57 BL/6 IL-10 deficient mice. Gene expression was compared during exponential growth in Bolton broth. Unpassaged (p0) C. jejuni 11168 was compared to the same strain after 1 passage (p1) and after three passages (p3) through the mice. Biological replicates: 4 for p0 v. p1, 3 for p0 v. p3
Project description:We designed a large scale gene expression study in Ts1Cje mice between P0 and P10 in order to measure the effects of trisomy 21 on a large number of samples (56 in total) in a tissue that is affected in Down syndrome (the cerebellum) and to quantify the defect during development in order to correlate gene expression changes to the phenotype observed. Keywords: Down syndrome, Ts1Cje, cerebellum, development, hypoplasia We analyzed gene expression in the cerebellum of Ts1Cje and euploid mice at P0, P3, P7 and P10 using pangenomic two colors microarrays containing 25 344 probes representing approximately 15 574 mouse genes. 56 samples from individual cerebellum were hybridized on 28 microarrays. On each microarray we hybridized a Ts1Cje sample versus an euploid sample and always a male versus a female. In addition on the same microarray we always compared samples from mice of the same age or with a maximum difference of 4 days (P0 versus P3, P3 versus P7 or P7 versus P10).
Project description:Here, we investigate therapy-induced senescence (TIS) as a reversible mechanism of drug resistance in breast cancer cells. High-dose doxorubicin treatment was used to induce TIS in four distinct breast cancer cell lines and the drug resistance/sensitivity pattern of parental and TIS cells were investigated using a panel of FDA-approved anticancer molecules.
Proteome analysis confirmed the presence of the Senescence-Associated Secretory Phenotype (SASP), altered spliceosomal activity and proteins with significant role in immune evasion.
