Long noncoding RNAs (lncRNA) have been found to play critical roles in tumorigenesis and the development of various cancers, including hepatocellular carcinoma (HCC). Metastasis associated with lung adenocarcinoma transcript-1 (MALAT1) has been identified as an oncogene and prognostic biomarker in HCC. Here, we demonstrated that MALAT1 expression was obviously high in sorafenib-resistant HCC cells. Furthermore, knockdown of MALAT1 increased sorafenib sensitivity in nonresponsive HCC cells, whereas forced expression of MALAT1 conferred sorafenib resistance to responsive HCC cells in vitro. In addition, loss/gain-of-function assays revealed that MALAT1 promoted cell proliferation, migration, and epithelial–mesenchymal transition in HCC cells. Mechanistically, MALAT1 regulated Aurora-A expression by sponging miR-140-5p, thus promoting sorafenib resistance in HCC cells. Moreover, MALAT1 inhibition enhanced the antitumor efficacy of sorafenib in vivo. Clinically, we found that MALAT1 expression was negatively correlated with miR-140-5p expression but positively correlated with Aurora-A expression in patients with HCC and that upregulated MALAT1 was closely correlated with poor survival outcomes in patients with HCC. These findings indicated that MALAT1 may be a novel target for prognosis prediction and therapeutic strategies in patients with HCC treated with sorafenib.

Despite advances in oral health care, inequalities in oral health outcomes persist due to problems in access. With proper training, primary care providers can mitigate this inequality by providing oral health education, screening, and referral to advanced dental treatment. Diverging sets of oral health competencies and guidelines have been released or endorsed by multiple primary care disciplines. The aim of this study was to transform multiple sets of competencies into Entrustable Professional Activities (EPAs) for oral health integration into primary care training. A scoping review of the literature between January 2000 and December 2016 was conducted according to PRISMA methodology to identify all existing sets of competencies. The following primary care disciplines were included in the search: allopathic/osteopathic medical schools and residency programs in family medicine, internal medicine, and pediatrics; physician assistant programs; and nurse practitioner programs. Competencies were compared using the Health Resources and Services Administration Integration of Oral Health and Primary Care Practice competencies as the foundational set and translated into EPAs. The resulting EPAs were tested with a reactor panel. The scoping review produced 1,466 references, of which 114 were selected for full text review. Fourteen competencies were identified as being central to the integration of oral health into primary care. These were converted to seven EPAs for oral health integration into primary care and were mapped onto Accreditation Council for Graduate Medical Education residency competency domains as well to the Association of American Medical Colleges EPAs for graduating medical students. The resulting EPAs delineate the essential, observable work required of primary care providers to ensure that oral health is treated as a critical determinant of overall health.

Purpose: Oral and craniofacial conditions or diseases can impact an individual's health and quality of life. The purpose of this study was to assess the perceived oral health related quality of life (OHRQoL) of children, and evaluate the reported level of agreement between caregivers and their children.Methods: Purposive sampling was used to recruit children ages 8-15, and their caregivers from a dental clinic in a pediatric hospital for this descriptive, cross-sectional study. A modified version of a validated measure, Child Oral Health Impact Profile-Short Form (COHIP-SF), was used for a 22-item questionnaire encompassing three subscales: oral health, functional well-being, and social emotional well-being. Two additional items were included to assess child/caregiver's level of agreement. A dental chart review was also conducted to assess the child's overbite, overjet, and decayed surfaces. Data were analyzed through descriptive statistics and examined for assumptions of normality and linearity.Results: Sixty child/caregiver pairs (n=120) participated in this study. Overbite, overjet and decayed surfaces were not found to be related to any OHRQoL variable, including child/caregiver ratings and overall agreement (p>.05). Average OHRQoL scores for caregivers found to be more positive those of their children (p=.02). Agreement between caregivers and the child's gender was shown to be significant (p=.01). Female child scores differed significantly from males with respect to their caregiver responses (p=.02). Caregivers rated a higher OHRQoL for female children, thus overestimating their female child's reported OHRQoL.Conclusions: The moderate level of agreement found between children and caregivers reinforces the importance of including the child, as well as the caregiver, when assessing OHRQoL.

Purpose: The purpose of this study was to analyze associations between the oral health literacy of refugees and two oral health outcomes: dental care utilization and oral health self-efficacy.Methods: A convenience sample of refugees in the greater Los Angeles area attending English as a second language (ESL) classes sponsored by two refugee assistance organizations was used for this cross-sectional, correlational study. Participants responded to a questionnaire using items from the Health Literacy in Dentistry (HeLD) scale, in addition to items concerning dental care utilization and oral health self-efficacy. Descriptive statistics, chi-square and Fisher's Exact tests were used to analyze results.Results: Sixty-two refugees volunteered to participate (n=62). A majority of the respondents were female from Iraq or Syria, and selected the item “with little difficulty” for all oral health literacy tasks. In regards to dental care utilization, more than half of the respondents were considered high utilizers (63%, n=34) meaning they had visited a dental office within the last year; while a little more than one-third (37%, n=20), were low utilizers, indicating they had either never been to a dental office or it had been more than one year since they had dental treatment. Statistical analysis showed associations between oral health literacy and dental care utilization. However, few associations between oral health literacy and oral health self-efficacy were identified (p=0.0045).Conclusions: Results support the provision of easily obtainable and understandable oral health information to increase oral health literacy and dental care utilization among refugee populations. Future research is needed to examine the oral health literacy among refugees resettling in the United States.

Lipid rafts are highly ordered regions of the plasma membrane that are enriched in cholesterol and sphingolipids and play important roles in many cells. In hematopoietic stem and progenitor cells (HSPCs), lipid rafts house receptors critical for normal hematopoiesis. Lipid rafts also can bind and sequester kinases that induce negative feedback pathways to limit proliferative cytokine receptor cycling back to the cell membrane. Modulation of lipid rafts occurs through an array of mechanisms, with optimal cholesterol efflux one of the major regulators. As such, cholesterol homeostasis also regulates hematopoiesis. Increased lipid raft content, which occurs in response to changes in cholesterol efflux in the membrane, can result in prolonged receptor occupancy in the cell membrane and enhanced signaling. In addition, certain diseases, like diabetes, may contribute to lipid raft formation and affect cholesterol retention in rafts. In this review, we explore the role of lipid raft-related mechanisms in hematopoiesis and CVD (specifically, atherosclerosis) and discuss how defective cholesterol efflux pathways in HSPCs contribute to expansion of lipid rafts, thereby promoting myelopoiesis and thrombopoiesis. We also discuss the utility of cholesterol acceptors in contributing to lipid raft regulation and disruption, and highlight the potential to manipulate these pathways for therapeutic gain in CVD as well as other disorders with aberrant hematopoiesis.

ABSTRACT

OleA, a member of the thiolase superfamily, is known to catalyze the Claisen condensation of long-chain acyl coenzyme A (acyl-CoA) substrates, initiating metabolic pathways in bacteria for the production of membrane lipids and β-lactone natural products. OleA homologs are found in diverse bacterial phyla, but to date, only one homodimeric OleA has been successfully purified to homogeneity and characterized in vitro. A major impediment for the identification of new OleA enzymes has been protein instability and time-consuming in vitro assays. Here, we developed a bioinformatic pipeline to identify OleA homologs and a new rapid assay to screen OleA enzyme activity in vivo and map their taxonomic diversity. The screen is based on the discovery that OleA displayed surprisingly high rates of p-nitrophenyl ester hydrolysis, an activity not shared by other thiolases, including FabH. The high rates allowed activity to be determined in vitro and with heterologously expressed OleA in vivo via the release of the yellow p-nitrophenol product. Seventy-four putative oleA genes identified in the genomes of diverse bacteria were heterologously expressed in Escherichia coli, and 25 showed activity with p-nitrophenyl esters. The OleA proteins tested were encoded in variable genomic contexts from seven different phyla and are predicted to function in distinct membrane lipid and β-lactone natural product metabolic pathways. This study highlights the diversity of unstudied OleA proteins and presents a rapid method for their identification and characterization.

IMPORTANCE Microbially produced β-lactones are found in antibiotic, antitumor, and antiobesity drugs. Long-chain olefinic membrane hydrocarbons have potential utility as fuels and specialty chemicals. The metabolic pathway to both end products share bacterial enzymes denoted as OleA, OleC, and OleD that transform acyl-CoA cellular intermediates into β-lactones. Bacteria producing membrane hydrocarbons via the Ole pathway additionally express a β-lactone decarboxylase, OleB. Both β-lactone and olefin biosynthesis pathways are initiated by OleA enzymes that define the overall structure of the final product. There is currently very limited information on OleA enzymes apart from the single representative from Xanthomonas campestris. In this study, bioinformatic analysis identified hundreds of new, putative OleA proteins, 74 proteins were screened via a rapid whole-cell method, leading to the identification of 25 stably expressed OleA proteins representing seven bacteria phyla.
