Project description:The coordination of chloroplast and nuclear genome status are critical for plant cell function, but the mechanism remain largely unclear. In this study, we report that Arabidopsis thaliana CHLOROPLAST AND NUCLEUS DUAL-LOCALIZED PROTEIN 1 (CND1) maintains genome stability in both the chloroplast and the nucleus.
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:Environmental enteric dysfunction (EED) is a major impediment to the Sustainable Development Goals of improved childhood survival and healthy growth worldwide. Few studies have directly examined the affected intestine, limiting the development of effective interventions. The Study of Environmental Enteropathy and Malnutrition (SEEM, Pakistan) followed 416 at-risk children prospectively from birth to 24 months of age in a rural district of Pakistan with a high prevalence of undernutrition. The duodenal genome-wide methylome and transcriptome was determined in 52 undernourished SEEM participants refractory to nutritional interventions and 42 North American healthy controls and celiac disease patients. Biomarkers were measured at 9 months and tested for association with growth at 24 months in training (n=166) and validation (n=84) groups within SEEM.
