Project description:Two patients with alopecia areata were treated with systemic ruxolitinib. Skin biopsies were taken before starting treatment and 12 weeks after starting treatment. We used microarrays to assess changes in gene expression of affected skin before and after starting treatment Two patients with alopecia areata were recruited for our study. Skin biopsies of affected scalp were taken prior to starting treatment with oral ruxolinitib. Additional skin biopsies were taken 12 weeks after starting treatment. Scalp skin biopsies were taken from patients without alopecia areata for comparison. RNA was extracted, cDNA libraries were made and profiled on affymetrix microarray chips.
Project description:This study was an open-label, clinical trial to investigate tofacitinib 5 mg to 10 mg PO twice daily in the treatment of moderate/severe alopeica areata and to identify if gene expression of the scalp correlates with clinical response. Gene expression profiling was performed on scalp biopsies of alopecia areata patients taken at baseline and up to 24 weeks of treatment of tofacitinib. We applied both naïve and supervised clustering to this dataset in order to assess two features: the overall molecular effect of tofacitinib treatment on patient samples, and the concordant molecular response of the disease. The former was assessed by an unbiased, unsupervised differential expression analysis and the latter was measured by response to previously published gene expression signatures defining AA pathology. To ensure parity of the data, for this analysis we only included patient samples that had matched pre-treatment, Tx-00, and 24 weeks of treatment, Tx-24, samples. Gene expression profiles and Alopecia Areata Disease Activity Index (ALADIN) scores correlated with clinical response.
Project description:We present the biopsy sub-study results from the first randomized, placebo-controlled clinical trial in patients with alopecia areata (AA) with ≥50% scalp hair loss and ≤7 years since the last AA episode. In this sub-study, we evaluated the molecular responses to PF-06651600, an oral inhibitor of JAK3 and the tyrosine kinase expressed in hepatocellular carcinoma (TEC) kinase family, and PF-06700841, an oral TYK2/JAK1 inhibitor, versus placebo in nonlesional and lesional scalp biopsies of biopsy samples from patients with AA.
Project description:open-label single-arm pilot phase II clinical trial of Regorafenib as a single agent in Frail Patients With Metastatic Colorectal Cancer. Blood samples for determination of serum miRNAs were taken on entry into the study and at the time of disease progression.

Project description:The impact of PDF supplementation with alanyl-glutamine (AlaGln) on peritoneal immune-competence in 6 patients in an open-label, randomized, crossover pilot trial (EudraCT 2012-004004-36) was tested by relating functional test results to transcriptome changes (RNAseq and miRNA analysis) in PD effluent cells.

Project description:This goal of these studies were to examine gene expression profiles of skin from patients with alopecia areata undergoing treatment with oral ruxoltinib. Microarray analysis was performed to assess changes in gene expression in affected scalp skin.
