BACKGROUND: Prenatal maternal stress might be a risk for the developing fetus and may have long-lasting effects on child and adult vulnerability to somatic and psychiatric disease. Over-exposure of the unborn to excess glucocorticoids and subsequent alteration of fetal development is hypothesized to be one of the key mechanisms linking prenatal stress with negative child outcome. METHODS: In this prospective longitudinal study, mothers-to-be (n = 405) in late pregnancy (36...

In recent years, there has been a great deal of interest in ex-vivo genetic modification of mesenchymal stem cells (MSCs) to meet various biomedical needs. Considering the self-renewal potential of MSCs, it is critically important to ensure that transfection vectors (gene carriers) do not induce genotoxicity because they could theoretically turn a single stem cell into a cancer-initiating cell. Unfortunately, there is currently no reliable, unbiased, and quantitative method to measure genotoxicity (micronuclei formation) of gene carriers directly in transfected MSCs...

Janus tyrosine kinase 2 (JAK2) mediates downstream signaling of cytokine receptors in all hematological lineages, constitutively active somatic JAK2 mutations play key roles in the pathology of myeloproliferative neoplasms (MPNs). Recently, germline JAK2 mutations are also associated with triple-negative MPNs. A novel germline mutation JAK2 V625F is reported to be involved in a subset of MPNs patients. However, the pathogenesis of this mutation caused MPN is still unclear. In this study, the homology models of JAK2 V625F showed that the newly formed interaction between F625 and Y613 disrupted the JAK2 JH1-JH2 domain interactions was responsible for its activation, when F625 and Y613 interaction was disrupted, its activity significantly decreased...

INTRODUCTION: The cause of abdominal pain (AP) in gastroparesis (Gp) is often not known; hence, its treatment can be challenging. Preoccupation with or increased attention (hypervigilance) to pain is associated with perceived pain severity and psychosocial disability. The aims of this study were to (1) characterize AP in Gp patients into neuropathic and nociceptive pain components; (2) assess these patients for hypervigilance to pain. MATERIALS AND METHODS: Gp patients with AP as an important symptom, seen from June 2017 to November 2017 were given validated questionnaires to characterize their AP...

Epigenetic reprogramming and somatic cell nuclear transfer (SCNT) cloning efficiency were recently enhanced using histone deacetylase inhibitors (HDACis). In this study, we investigated the time effect of CI994, an HDACi, on the blastocyst formation rate, acetylation levels of H3K9 and H4K12, DNA methylation levels of anti-5-methylcytosine (5mC), and some mRNA expression of pluripotency-related genes in pig SCNT embryos. Treatment with 10 μM CI994 for 24 hours significantly improved the blastocyst formation rate of SCNT embryos in comparison with the untreated group (p < 0...

Here we present protocols to isolate primary differentiated cells and turn them into stem/progenitor cells (SCs) of the same lineage by transient expression of the transcription factor YAP. With this method, luminal differentiated (LD) cells of the mouse mammary gland are converted into cells that exhibit molecular and functional properties of mammary SCs. YAP also turns fully differentiated pancreatic exocrine cells into pancreatic duct-like progenitors. Similarly, to endogenous, natural SCs, YAP-induced stem-like cells ("ySCs") can be eventually expanded as organoid cultures long term in vitro, without further need of ectopic YAP/TAZ, as ySCs are endowed with a heritable self-renewing SC-like state...

INTRODUCTION: Sexual assault (SA) is alarmingly common and is associated with higher prevalence of psychiatric and medical conditions. However, many prior studies are limited to cross-sectional designs. Health care systems with electronic health records provide unique longitudinal data to examine whether SA is associated with changes in health and health care utilization. METHODS: The sample included 1350 Kaiser Permanente Northern California adult female patients with a SA diagnosis from 2009 to 2015 and 4050 adult female patients without a SA diagnosis, matched on age, medical facility, and continuous enrollment during the study period...

Early life stress (ELS) is associated with altered processing of threat signals, and increased lifetime risk of anxiety and affective pathology, disorders that disproportionately affect females. We tested the impact of a limited bedding paradigm of ELS (from P4-11) on contextual threat learning, context memory, footshock sensitivity, and anxietylike behavior, in adult male and female mice. To examine contextual threat learning, mice conditioned by context/footshock association were tested 24 hr later for the context memory...

Objective: Circulating cell-free tumor DNA (cfDNA) is the DNA released by apoptotic and necrotic cells of the primary tumor into the blood during the period of tumor development. The cfDNA reflects the genetic and epigenetic alterations of the original tumor. TP53 mutations are a defining feature of high-grade serous ovarian carcinoma. We optimized the methods for detecting TP53 mutations in cfDNA from blood samples. We confirmed the correlation of TP53 mutation in primary ovarian cancer tissue and it in cfDNA using digital polymerase chain reaction (dPCR)...

Purpose: The development of next-generation sequencing (NGS) has revolutionized the understanding of oncogenesis of multiple types of cancer, including non-small cell lung cancer (NSCLC). However, there has been some debate over the utility of NGS for predicting patient prognosis and determining molecular targeted therapy. Therefore, we sought to demonstrate the numerous applications of NGS in the prognostic predictions and treatment of NSCLC patients. Materials and methods: We performed NGS on either liquid or tissue tumor biopsies obtained from 53 NSCLC patients...

Constitutive expression of the Zea mays L. (maize) morphogenic transcription factors Baby Boom ( Bbm ) and Wuschel2 ( Wus2 ) in maize can not only greatly increase transformation efficiency but can also induce phenotypic abnormalities and sterility. In an effort to alleviate the pleiotropic effects of constitutive expression, a genome wide search was undertaken to find suitable maize promoters to drive tissue and timing-specific expression of the transformation enhancing genes Bbm and Wus2 . A promoter from a maize phospholipid transferase protein gene ( Zm - PLTP pro ) was identified based on its expression in leaves, embryos, and callus while being downregulated in roots, meristems, and reproductive tissues...

We investigated the means and timing by which mutations become fixed in the human colonic epithelium by visualizing somatic clones and mathematical inference. Fixation requires two sequential steps. First, one of approximately seven active stem cells residing within each colonic crypt has to be mutated. Second, the mutated stem cell has to replace neighbors to populate the entire crypt in a process that takes several years. Subsequent clonal expansion due to crypt fission is infrequent for neutral mutations (around 0...
