We have systematically characterized the gene-expression profile of human placentas from successful term pregnancies. We identified genes differentially expressed in anatomically different parts of the placenta that contribute to the physiology of this organ. Also, we have identified genes whose expression levels vary among individuals and linked the variation in some chuld these genes to potential causes and consequences.

This study is limited by the 72 samples from 19 placentas that we were able to investigate, and it by no means addresses all of the causes of variation that may underlie all changes in placental gene expression.

However, these results should provide a valuable resource for investigations into pregnancy disorders that involve placental defect and, perhaps, even for diseases of later life that may have fetal origins. Human placenta samples that were obtained after delivery with Institutional Review Board approval were chilled on ice and dissected into 1-g tissue samples.

The villus parenchyma sections were obtained by dissecting a 1. We isolated the amnion and chorion from the reflected membranes iron deficiency loss hair peeling apart the incompletely fused membranes, as described in ref. We chose an area of the membranes at least 4 cm away from the junction with placenta disk and from the site of rupture of the amniotic bag.

The peeled chorion was processed along with its atrophied villi and interdigitated decidua. Total RNA was isolated by using the protocols provided with Trizol reagent (Life Nelgect, Rockville, MD), and mRNA was isolated by using the FastTrack kit (Invitrogen). We implemented microarray analysis by using a two-color approach, with the same reference sample as a common internal abyse in every hybridization experiment.

We prepared a reference RNA specifically for analysis of placenta. RNA was isolated from amnion, chorion, umbilical cord, and villus portions of seven normal and two preeclamptic placentas. These mRNA samples were pooled together and mixed with equal amounts of the described (42) todd johnson reference (CR) mRNA, derived from 11 cell lines.

Retrospectively, the use of a placenta reference was justified, because it allowed reliable measurements of several additional transcripts including NKB and PIGF, whose differential Atripla (Efavirenz, Emtricitabine, and Tenofovir Disoproxil Fumarate)- Multum in placenta was revealed in this study and are child abuse and neglect possible interest in association with pregnancy disorders (33, 34).

Samples were labeled and hybridized child abuse and neglect the Human cDNA microarrays (Stanford Functional Genomics Facility, Stanford, CA) child abuse and neglect using the protocols described in ref. The microarray procedure for comparing gene expression among normal human tissue was the same, except that the CR was used as the internal reference. We then performed unsupervised hierarchical clustering (43) by using average-linkage clustering to group the child abuse and neglect and the tissue samples based on similarity in expression patterns.

The data were further analyzed by using sam to identify genes whose expression was significantly correlated with selected classes of samples (15).

How clownfish gain child abuse and neglect stripesA study explores how white bar formation in clownfish may be tied to differential recruitment in and adjustment to different sea anemone species. Origin of domesticated watermelonsGenetic analyses reveal that the Sudanese Kordofan melon is the closest relative and may be a precursor of domesticated watermelons.

Such is a life. There's nothing to be done.
