Project description:We analysed the DNA methylation patterns of inguinal white adipose tissue in M-SCT floxed and M-SCT KO, the results indicated a significant widepread hypermethylation modification in M-SCT floxed which contributed to the increased obesity susceptibility of M-SCT floxed
Project description:The purpose of this study is to evaluate the safety and efficacy of SCT-I10A combined SCT200 or SCT-I10A combined SCT200 plus chemotherapy in advanced esophageal squamous cell carcinoma and colorectal cancer
Project description:Patients with acute leukemia who are unable to achieve complete remission prior to allogeneic hematopoietic stem cell transplantation (SCT) have dismal outcomes with relapse rates well in excess of 60%. Haplo-identical SCT (haplo-SCT) may allow enhanced graft-versus-leukemia (GVL) effects by virtue of HLA class I/II donor-host disparities but typically requires intensive immune-suppression with post-transplant cyclophosphamide (PT-Cy) to prevent lethal graft-versus-host disease (GVHD). Here we demonstrate in preclinical models that glucocorticoid administration from day -1 to +5 inhibits alloantigen presentation by professional recipient antigen presenting cells in the gastrointestinal tract and prevents donor T-cell priming and subsequent expansion therein. In contrast, direct glucocorticoid signaling of donor T-cells promotes chemokine and integrin signatures permissive of preferential circulation and migration into the bone marrow, promoting donor T-cell residency.
Project description:RNA-seq analysis of Pseudomonas sp OST1909 exposed to various preparations of naphthenic acids samples led to the identiifcation of many NA-induced genes.
Project description:This study provides comparative RNA-seq datasets for four freshwater bacterial isolates, Pseudomonas sp. FBCC-B13192, Herbaspirillum sp. FBCC-B12834, Pantoea sp. FBCC-B5559, and Micrococcus sp. FBCC-B5738, cultured under iron-replete (+100 uM FeCl3) and iron-limited (no FeCl3) conditions. Iron availability is a key factor influencing bacterial fitness, and iron limitation is known to activate siderophore biosynthesis, iron transport, and homeostasis pathways. A total of eight libraries generated in 2024 and 2025 were analyzed, comprising 349.9 million processed reads. Reference-guided mapping rates varied among strains, with higher mapping efficiency observed in Pseudomonas, Herbaspirillum, and Pantoea, while Micrococcus showed comparatively lower mapping rates under both conditions. Differential expression analysis revealed strain-specific responses to iron limitation. Genes related to pyoverdine and ferrichrome uptake were enriched in Pseudomonas and Herbaspirillum, enterobactin-associated pathways were prominent in Pantoea, and genes associated with siderophore production, heme utilization, and Fe-S cluster assembly were identified in Micrococcus. Raw sequencing data are available in the NCBI Sequence Read Archive under BioProject PRJNA1456794, and processed data are deposited in a public repository. These datasets provide a valuable resource for understanding bacterial adaptation to iron availability and for comparative transcriptomic analyses.
Project description:The pyrite mine of Lousal, Grândola, Portugal, was discovered in 1882 and extensively exploited from 1900 until its closure in 1988 when the mining ores were not viable economically. Aiming at becoming a cultural-touristic center, the mining area was rehabilitated raising a Mining Museum and a Science Centre along with the reopening of a mining gallery for public access. In recent times, aerobiological studies on subterranean environments such as caves, mines and archeological necropolis revealed to be an important source of novel bacteria, from which their biotechnological potential are under study. Here we present a Pseudomonas sp. isolated from the mine air with potential secondary metabolite biosynthesis, resistance to antibiotics and virulence factors.
