ABSTRACT: Human-Modified Biogeographic Patterns and Conservation in Game Birds: The Dilemma of the Black Francolin (Francolinus francolinus, Phasianidae) in Pakistan
Project description:Ground water Arsenic (As) toxicity is a global problem and millions of people are exposed to elevated levels (more than WHO advised maximum limit of 10µg/L) through drinking water. The exposure is associated with various cancerous and non-cancerous diseases. It may alter DNA methylation profiles of inviduals and suppress the activity of various genes giving rise to different diseases. Pakistan, a developing country in South Asian region, also has reported elevated ground water As levels in various investigations since 2005. However, a very limited biomonitoring studies have been conducted in this context while no study reports molecular changes associated with drinking water As exposure in Pakistan. Within this context, the present study aimed to investigate genome-wide DNA methylation profiles of the exposed subjects in two districts of Punjab Province Pakistan, i.e Lahore and Kasur. The population was stratified into three exposure groups comprising Low, Medium and High exposure based on their urinary arsenic levels. Genome-wide DNA methylation profiles were obtained using MeDIP in combination with NimbleGen 2.1M Deluxe Promotor arrays.
Project description:Ground water Arsenic toxicity is the global problem and millions of people are exposed to elevated levels through drinking water than WHO permiscible limit of 10µg/L. The exposure is associated with various cancerous and non-cancerous diseases. It may alter the gene expression profile of invidual and suppress the activity of various genes giving rise to different diseases. Pakistan, a developing country in South Asian region, also have different areas reported to have elevated Ground water As. levels since 2005. The Present Study aimed to investigate Transcriptome profile of the exposed subjects in two districts of Punjab Province Pakistan. i.e Lahore and Kasur. The population was stratified into three exposure groups comprising Low, Medium and High exposure based on their urinary arsenic levels. We used Agilent Microarrays platform for Transcriptomics analysis and Linear mixed model was used to find differential gene expression associated with Arsenic exposure
Project description:Our paper presents the results of a study in which we used whole genome bisulfite sequencing (WGBS), RNA-Seq (i.e. transcriptomics), high-CO2 physiology experiments, and spatiotemporally separated samples isolated in situ (i.e. directly from the ocean) to examine the metabolic potential of genome-wide cytosine (5mC) methylation (i.e. epigenomics), its potential impacts to transcriptional dynamics under both present-day and future ocean acidification conditions, and its biogeographic conservation in the globally-significant, biogeochemically-critical marine cyanobacterium Trichodesmium.
