Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:1,322 morphologically unidentified fragmentary bone specimens were analyzed using MALDI-TOF and a subset of 341 bone specimens with LC-MS/MS in order to characterize their proteome for species identification and potential hominin specimens related to the LRJ transitional period derived from the site Ilsenhöhle Ranis, Germany (50°39.7563’N, 11°33.9139’E).
Project description:Despite the advancement of genomic classification of breast cancer, current clinical tests and treatment decisions are commonly based on protein level information. Formalin-fixed paraffin-embedded (FFPE) tissue specimens are widely available and can be directly linked to extended clinical outcomes. We performed comprehensive proteomic profiling of 300 FFPE breast cancer surgical specimens, 75 of each PAM50 subtype, with linked clinical outcomes. Using our highly sensitive SP3-Clinical Tissue Proteomics platform, we quantified 4214 proteins across all 300 samples. The analysis identified a distinct proteomic group characterized by high expression of immune response proteins and favorable survival rates. Four clinically distinct proteomic clusters within samples classified as triple negative breast cancer by immunohistochemistry had features of “basal-immune hot”, “basal-immune cold”, “mesenchymal”, and “luminal androgen receptor”. Our proteomic analysis characterizes the heterogeneity of breast cancer in a clinically-applicable manner, identifies potential biomarkers and therapeutic targets, and provides a resource for clinical breast cancer classification.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.
