Project description:Single cell RNA Seq and bioinformatic analysis are used to study what processes are important for the molecular reprogramming of GMPs after 5-FU treatment. Samples were collected at different time points (0, 8, 10, 12 and 14 days post treatment)
Project description:The nuclear proteome harbors a sheer number of regulatory proteins, including transcription factors (TFs). Profiling of nuclear proteome during all-trans-retinoid acid(ATRA)-induced differentiation of HL60 cells allows to unveil molecular mechanisms of granulocytic maturation. It is especially important to have an understanding of molecular perturbations at the early stages of the differentiation process. Applying proteomic profiling using isobaric labeling coupled with alkaline fractionation (TMT/2D) we identified 1860 nuclear proteins with high confidence (FDR<0.01, at least 2 unique peptides per protein). Among them 136, 226, 280, 312 and 241 proteins were found to be altered at 3, 6, 9, 12, and 72 h in HL60 cell nuclear fraction under ATRA treatment.
Project description:We pooled 100,000 cells from the 12 scRNA+TCRab-seq samples from peripheral blood from three time points (n=4, samples at 0, 3, and 12 months) to understand the landscape of immune subsets in CML during the course of dasatinib+IFN-α treatment
Project description:Searching for new strategies of acute myeloid leukemia (AML) treatment is of particular interest. Cell lines, e. g. HL-60 and NB4, represent model systems to study molecular features of leukemic cells. The all-trans-retinoic acid (ATRA) has proven itself to be an effective treatment for one of AML subtypes, i.e., acute promyelocytic leukemia (APL). At the same time, ATRA causes granulocytic differentiation of non-APL leukemic cells in vitro. Combination of new therapeutics with ATRA could improve efficiency of treatment. Studying the proteome perturbation in leukemic cells under the ATRA treatment allows to determine potential regulatory molecules that could be affected pharmacologically. Thus, the TMT-based proteomic profiles of HL-60, NB4, and K562 cell lines under the ATRA treatment were obtained at 0, 3, 12, 24, and 72 h after the ATRA treatment.
Project description:Asthma bronchiale is an inflammatory disease of the respiratory airways and a major factor of increasing health care costs worldwide. The molecular actors leading to asthma are not fully understood and require further investigation. The aim of this study was to monitor the proteome during asthma development from early inflammatory to late fibrotic stages. A time-course-based ovalbumin (OVA) mouse model was applied to establish an asthma phenotype and the lung proteome was analysed at four time points during asthma development (0 weeks = control, 5 weeks, 8 weeks and 12 weeks of OVA treatment).
Project description:We examined how glyceolin I, a phytoalexin from soybeands, affects gene expression in breast cancer cells. mRNA was collected at time points of 0, 6, 12, and 24 hours, and mRNA-seqs were performed.
Project description:This study used transcriptomic analysis to evaluate how aging specifically affects the functional host response to influenza in the mouse lung. Adult (12-16 weeks) and aged (72-76 weeks) female BALB/c mice were infected with influenza (A/Puerto Rico/8/34 (H1N1) (A/PR8)) intranasally (instilled with 50 μl of PBS containing 50-100 pfu PR8). Lungs were processed for RNA expression analysis via Agilent microarray at various time points. Time points were 0, 1, 3, 5, 7, 9 days post infection.
Project description:Circadian rhythmicity in renal function suggests a requirement for circadian adaptations in renal metabolism. We studied circadian changes in renal metabolic pathways using integrated transcriptomic, proteomic and metabolomic analysis performed on control mice and mice deficient in the circadian clock gene Bmal1 in the renal tubule (cKOt mice). Proteins were extracted from whole kidneys of 60 mice. Of these, 30 were conditional knockouts of Arntl (Bmal1) and 30 were of control genotype. They were housed under 12-hours light/12-hours dark cycles and were sacrificed at six different time points: zeitgeber time ZT 0, ZT 4, ZT 8, ZT 12, ZT 16, ZT 20 ( ZT 0 being the time of light on and ZT 12 the time of light off). Five replicates per genotype and time point were analysed.
