Description
The acute respiratory distress syndrome (ARDS) is a highly lethal syndrome characterized by hypoxemia and bilateral lung infiltrates in response to an inciting event such as sepsis. Allogeneic bone marrow transplantation (BMT) is a life-saving treatment for patients with hematologic malignancies that can be complicated by ARDS. We sought to identify blood gene expression signatures that distinguish whether ARDS in BMT may be a distinct pathobiologic entity from ARDS in non-BMT patients. RNA-Seq was used to measure whole blood transcript expression differences between 26 patients meeting the Berlin definition of ARDS: 8 patients without BMT and 5 BMT patients with ARDS from the Brigham and Women's Registry of Critical Illness (RoCI), as well as 7 non-BMT patients with sepsis and 6 BMT patients with sepsis. RNA was globin cleared using the Ambion GLOBINclear kit prior to preparation of poly(A)-selected RNA-Seq libraries with the Illumina TruSeq method. An Illumina HiSeq 2500 instrument was used to generate 75 base pair paired-end reads, which were aligned to the hg38 reference genome using STAR. Differential expression analysis was performed using DESeq2. Overall design: mRNA profiles obtained via RNA-Seq for whole blood samples from ARDS patients with and without BMT

Description
Increasing evidence across malignancies suggests that infiltrating T cells at the site of disease are crucial to tumor control. We hypothesized that marrow-infiltrating immune populations play a critical role in response to donor lymphocyte infusion (DLI), an established and potentially curative immune therapy whose precise mechanism remains unknown. We therefore analyzed marrow-infiltrating immune populations in 29 patients (22 responders, 7 nonresponders) with relapsed chronic myelogenous leukemia who received CD4+ DLI in the pre-tyrosine kinase inhibitor era.

Description
Transplantation with low numbers of hematopoietic stem cells (HSCs), found in many of the publically accessible cryopreserved umbilical cord blood (UCB) units, leads to delayed time to engraftment, high graft failure rates, and early mortality in many patients. A chemical screen in zebrafish identified the prostaglandin compound, 16,16 dimethyl prostaglandin E2 (dmPGE2), to be a critical regulator of hematopoietic stem cell homeostasis. We hypothesized that an ex vivo modulation with dmPGE2 prior to transplantation would lead to enhanced engraftment by increasing the effective dose of hematopoietic stem cells (HSCs) in cord blood. A phase I trial of reduced-intensity double UCB transplantation was performed to evaluate safety, rates of engraftment and fractional chimerism of dmPGE2 enhanced UCB units. To explore potential causes of the lack of enhanced efficacy in the first cohort, we characterized HSCs to determine whether the prostaglandin pathway was being activated under the ex vivo incubation conditions (4C, 10M dmPGE2, 60 minutes). Incubation conditions were identified (37C, 10M dmPGE2, 120 minutes) that maximize the activation of the prostaglandin pathway by dmPGE2 in human CD34+ cells.

Description
Umbilical cord blood (UCB) is a valuable source of hematopoietic stem cells (HSCs) for use in allogeneic transplantation. Key advantages of UCB are rapid availability and less stringent requirements for HLA matching. However, UCB contains an inherently limited HSC count, which is associated with delayed time to engraftment, high graft failure rates and early mortality. 16,16 dimethyl prostaglandin E2 (dmPGE2) was previously identified to be a critical regulator of HSC homeostasis and we hypothesized that a brief ex vivo modulation could improve patient outcomes by increasing the effective dose of HSCs.

To ask whether MANF contributes to the rejuvenating effects of heterochronic parabiosis, we generated heterochronic pairs in which 20 month old WT mice were combined with either 4 month old MANFHet (O-YgHet) or WT (O-YgWT) littermates, and maintained for 5 weeks before analysis. Control pairs in which old WT mice were combined together (O-O) were used. Livers were collected from each animal in the pair and RNA was sequenced for 5 independent animals/condition. Overall design: RNA was extracted and sequenced for 5 animals/condition

Description
Steroid hormone receptors are simultaneously active in many tissues and capable of altering each other's function. Estrogen receptor ? (ER) and glucocorticoid receptor (GR) are expressed in the uterus and their ligands have opposing effects on uterine growth. In endometrial tumors expressing high levels of ER, we surprisingly found that expression of GR is associated with poor prognosis. Dexamethasone reduced normal uterine growth in vivo; however, this growth inhibition was abolished in estrogen-induced endometrial hyperplasia. We observed low genomic binding site overlap when ER and GR are induced with their respective ligands; however, upon simultaneous induction they co-occupy more sites. GR binding is significantly altered by estradiol with GR recruited to ER bound loci that become more accessible upon estradiol induction. Gene expression responses to co-treatment were more similar to estradiol, but with novel regulated genes. Our results suggest phenotypic and molecular interplay between ER and GR in endometrial cancer. Overall design: ChIP-seq, ATAC-seq, and RNA-seq data collected from endometrial cancer cell lines induced with dexamethasone, estradiol, or the combination

The therapy-induced PML/RARA catabolism elicits the loss of APL-initiating cell self-renewal through PML NB reformation and P53 activation. These results explain the curative activity of the RA/arsenic combination, the resistance to RA of PLZF/RARA-driven APLs and they raise the prospect that activation of this PML/P53 checkpoint might have therapeutic values in other malignancies.
