High CD44 expression identifies a quiescent/chemoresistant leukemic population with enhanced E-Selectin binding in T-ALL

ABSTRACT: We used single cell RNA sequencing (scRNA-seq) to decipher cell heterogeneity of human T-cell Acute Lymphoblastic Leukemia (M18) recovered from Bone Marrow Adipose Tissue (BMAT)-poor (Femur and Thoracic Vertebrae) and -rich (Tail Vertebrae) sites of xenografted immunodeficient mice (NSG,nonobese diabetic/severe combined immunodeficiency / interleukin-2Rγ null). We wanted to know whether some human T-ALL cells recovered in BMAT-poor sites resemble to those from BMAT-rich site.

Transcriptomic consequence of the mutation in the response regulator gene gacA of the two-component regulatory system GacS/GacA in the rhizosphere biocontrol strain Pseudomonas aeruginosa M18

Project description:To investigate the influence of GacA on the genome-wide transcription of the rhizobacterium P. aeruginosa M18, DNA microarray experiments were carried out to compare the transcriptional profile of M18 with that of the gacA mutant grown to the early stationary phase (OD600 = 5.0 ~ 5.5) in KMB media. When compared with the M18 parental strain, the transcriptomic profile of gacA mutant revealed the significantly differential expression (increased or decreased by at least 2-fold as well as p-value < 0.05) of 839 genes, which represent approximately 15% of all 5696 annotated genes in the M18 genome. Of these 839 genes, 472 were downregulated and 367 genes were upregulated by the gacA mutation.

Comparison of white adipose tissue and bone marrow adipose tissue from New Zealand White rabbits

Project description:Microarray analysis of white adipose tissue (WAT) and bone marrow adipose tissue (BMAT) from 22-week-old or 13-week-old male New Zealand White rabbits. From both cohorts, BMAT was sampled from the distal tibia (dBMAT) and the radius and ulna (ruBMAT), while WAT was sampled from the inguinal (iWAT) and gonadal (gWAT) depots. From the 13-week-old cohort, BMAT was also sampled from the proximal tibia (pBMAT). Sufficient RNA could not be isolated from all tissues for all rabbits, so for some rabbits only a subset of tissues is included.

Temperature dependent gene expression levels at 28°C and 37°C for rhizophere Rhizosphere Originating Biocontrol Strain Pseudomonas aeruginosa M18

Project description:To further understand the gene expression characteristics of originating biocontrol strain Pseudomonas aeruginosa M18, we have applied whole genome microarray expression profiling as a discovery platform to to specify the temperature dependent expression of M18 genome at rhizosphere and human body temperature. We selected 28°C as temperature representative of the rhizosphere niches and 37°C for human body. The results from the temperature dependent transcriptome analysis are consistent to our previous published data that the phzM, ptsP and lasI genes expression is upregulated at 37°C. The comparison analysis of the M18 genome expressional profiles at 28°C and 37°C indicated a total of 605 gene expressed in a temperature dependent manner over about two fold at 28°C compared that at 37°C, covering 10.6% genes in M18 whole genome.

The effect of obesity on uterine receptivity is mediated by endometrial extracellular vesicles that control human endometrial stromal cell decidualization and trophoblast invasion

Project description:The objectives of the present study were to determine whether obesity impacts human decidualization and the endometrial control of trophoblast invasion (both of which are required for embryo implantation) and evaluate the potential involvement of endometrial extracellular vesicles (EVs) in the regulation of these physiological processes. Using primary human cell cultures, we first demonstrated that obesity is associated with significantly lower in vitro decidualization of endometrial stromal cells (ESCs). We then showed that the trophoblastic cell line’s invasive ability was greater in the presence of conditioned media from cultures of ESCs from obese women. Using mass-spectrometry-based quantitative proteomics, we found that EVs isolated from uterine supernatants of biopsies from obese women (vs. nonobese women) presented a molecular signature focused on cell remodeling and angiogenesis. Lastly, the results of functional assays indicated that supplementation of the culture medium with EVs from nonobese women can rescue (at least in part) the defect in in vitro decidualization described in ESCs from obese women. Lastly, the addition of endometrial EVs from obese women (vs. nonobese women) was associated with significantly greater invasive activity by HTR-8/SVneo cells. In conclusion, our results provided new insights into the endometrial EVs’ pivotal role in the poor uterine receptivity observed in obese women.

Gene expression levels in Rhizosphere Originating Biocontrol Strain Pseudomonas aeruginosa M18 producing different amounts of phenazine-1-carboxylate acid (PCA)

Project description:To further understand the gene expression characteristics of originating biocontrol strain Pseudomonas aeruginosa M18, we have applied whole genome microarray expression profiling as a discovery platform to to specify the PCA-dependent expression of M18 genome. We constructed a series of PCA-producing mutant strains (high PCA: M18MSU1; low PCA: M18MS; and no PCA: M18MSP1P2). The comparison analysis of the M18 mutants genome expressional profiles indicated that the expression of PCA in both M18MSU1 and M18MS alters the expression of a total of 545 different genes; however, the higher level of PCA in M18MSU1 altered more genes (489) as compared to M18MS (129). Cells were grown to OD600=5.0 (exponential phase) in PPM medium at 28℃. Three independent experiments were performed at each time.
