DNA-based cell typing in menstrual effluent identifies cell type variation by sample collection method: toward noninvasive biomarker development for women’s health

ABSTRACT: Menstrual effluent cell profiles have potential as noninvasive biomarkers of female reproductive and gynecological health and disease. We used DNA methylation-based cell type deconvolution (methylation cytometry) to identify cell type profiles in self-collected menstrual effluent. During the second day of their menstrual cycle healthy participants collected menstrual effluent using a vaginal swab, menstrual cup, and pad. Immune cell proportions were highest in menstrual cup samples, and epithelial cells were highest in swab samples. Our work demonstrates the feasibility and utility of menstrual effluent cell profiling in population-level research using remotely collected samples and DNA methylation.

Genome-wide methylation profiles of menstrual blood and vaginal fluid

Project description:The ability to predict the type of tissues or cells from molecular profiles of crime scene samples has practical implications in forensics. In order to identify body fluid-specific DNA methylation changes, genome-wide DNA methylation profiling was carried out for body fluids including menstrual blood and vaginal fluid obtained from 3 female donors aged 19, 27 and 38 years. The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles across approximately 450,000 CpGs in bisulfite converted DNA. Samples included 3 of each vaginal fluid and menstrual bloods collected on the first, second and third days of menstrual bleeding.

Gene expression profiling of nasal swabs samples from children with asthma or wheezing exacerbations.

Project description:Nasal swab specimens were collected from children who presented to the emergency department with an acute exacerbation of asthma or wheeze. Samples were also collected from control subjects. Convalescent/quiescent samples were collected from children who were followed-up at least 6 weeks after an acute exacerbation of asthma or wheeze. Gene expression was profiled on microarrays.

Exposure of Feathead Minnows to Municipal Wastewater Effluent Inhibits the Canonical Wnt Signaling Pathway in the Liver

Project description:Municipal wastewater effluent can impact its receiving environment. In the St. Lawrence River, male fish living downstream from Montreal exhibit increased hepatic vitellogenin, intersex, delayed spermatogenesis and altered immune function. Few studies have examined genome-wide effects associated with municipal effluent exposure in fish to decipher the mechanisms of toxicity. The present objective was to identify hepatic cellular signaling pathways in fathead minnows following exposure to municipal wastewater effluent. Immature minnows were exposed for 21 days to either 0% (Control) or 20% municipal effluent, the highest concentration in the St. Lawrence River. Hepatic RNA was extracted and used to hybridize a fathead minnow oligonucleotide microarray containing approximately 15K gene sequences. Sixteen samples were examined, 8 control samples and 8 exposed samples.

Genome-wide methylation profiles of forensically relevant body fluids [Set3]

Project description:The ability to predict tissue type and donor’s age from molecular profiles of crime scene samples has practical implications in forensics. In order to identify body fluid- and age-associated DNA methylation changes, genome-wide DNA methylation profiling was carried out for body fluids including blood, saliva, semen, menstrual blood, and vaginal fluid obtained from individuals aged 20 to 59. The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles across approximately 450,000 CpGs in bisulfite converted DNA. Samples included 12 of each blood, saliva and semen samples from 18 male donors aged 20 to 59, and 3 of each vaginal fluid and menstrual blood samples from 4 female donors in their twenties.
