Description
Histological resolution of the murine pancreas occurs within one week after injury. Whether histological resolution constitutes pancreatic recovery at a molecular level is not known. We performed RNA-sequencing on the recovering pancreas to determine the transcriptomic profile within the histologically recovered pancreas. We show that although there is histological resolution one week after injury in mice, compared to baseline (non-injured pancreas), there are still numerous differentially expressed genes (DEGs) at one and even two weeks after injury. Overall, the findings suggest the actual recovery takes longer than initially thought given the differential transcriptomic profile in the pancreas two weeks after injury compared to the baseline pancreas. There is also the possibility of a novel emerging pancreatic transcriptome upon recovery. Overall design: Acute pancreatitis was induced by caerulein hyperstimulation in both male and female C57BL/6 mice. Total RNA was extracted from the head of the murine pancreas in mice at baseline (non-injured; n=8), day 7 (post-injury; n=8), and day 14 (post-injury; n=7). Total stranded RNA libraries (ribo-depleted) were generated and sequenced on the Illumina NextSeq 500 NGS platform. RNA-seq data was analyzed for differentially expressed genes between baseline and day 7 and between baseline and day 14.

Description
Rett syndrome (RTT) is an X-linked neurodevelopmental disorder caused by mutations in the transcriptional regulator MeCP2. RTT is characterized by having apparently normal development until 6-18 months, when a progressive decline in motor and language functions begins and breathing abnormalities and seizures present. Despite intense research, the molecular targets of MeCP2 and their contribution to the disease are unknown. Here we present the first comprehensive and comparative transcriptomic and proteomic analysis in a RTT mouse model. Examining whole cortex tissue in symptomatic males (Mecp2Jae/y) and wild-type littermates, we have identified 391 genes and 465 proteins considered to be significantly altered. We observed an overall poor correlation between global gene and protein expression (Pearson correlation 0.12), yet 35 hits were common to both data sets, with 12 hits not described elsewhere. These 35 hits indicate disrupted cellular metabolism, calcium signaling, protein stability, DNA binding and cytoskeletal cell structure in the RTT cortex. Pathway analysis in both data sets identified biological pathways ubiquitous to multiple cell types as well as cell type specific pathways, underscoring the contributions of multiple central nervous system (CNS) cell populations to the disease pathogenesis. These findings prompted us to compare identified 'hits' to a publicly available database containing CNS cell type specific gene expression. This indicated approximately 32% of differentially expressed (DE) genes and 16% proteins were highly enriched in unique CNS cell types, while the remaining DE genes and proteins were ubiquitously expressed and not ascribable to any unique cell population. Our comparative transcriptome and proteome analysis in the cortex of RTT mice supports previous works indicating widespread CNS dysfunction. Overall design: Wild-type (WT) males were bred with heterozygous Mecp2tm1.1Jae/+ (Jaenisch) female mice. The whole cortex of mutant male mice (Mecp2Jae/y) along with WT littermates were collected after postnatal day 60 (P60+). An n of 4 biological replicates per genotype were used, with WT animals serving as controls. For RNA-Sequencing, 2 technical replicates were run per biological replicate.

Description
The genetic basis of hypodiploid acute lymphoblastic leukemia (ALL), characterized by aneuploidy and poor outcome, is unknown. Here, using complementary genome-wide profiling approaches, we show that hypodiploid ALL comprises two major subtypes that differ in the severity of aneuploidy, transcriptional profile and submicroscopic genetic alterations. Near haploid cases with 24-31 chromosomes frequently harbor alterations targeting receptor tyrosine kinase- and Ras signaling (71%) and IKZF3 (AIOLOS; 13%). In contrast, low hypodiploid ALL cases with 32-39 chromosomes are characterized by TP53 alterations (88%), almost half of which are present in non-tumor cells, and have alterations of IKZF2 (HELIOS; 53%) and RB1 (41%). Both near haploid and low hypodiploid tumors exhibit activation of Ras and PI3K signaling pathways, and are sensitive to PI3K inhibition, indicating that these drugs should be explored as a new therapeutic strategy for this frequently lethal form of leukemia.
