Description
Background: Gene expression analysis by RNA sequencing is now widely used in a number of applications surveying the whole transcriptomes of cells and tissues. The recent introduction of ribosomal RNA depletion protocols, such as RiboZero, has extended the view of the polyadenylated transcriptome to the poly(A)- fraction of the RNA. However, substantial amounts of intronic transcriptional activity has been reported in RiboZero protocols, raising issues regarding their potential nuclear origin and the impact on the actual sequence depth in exonic regions. Method: Using HEK293 human cells as source material, we assessed here the impact of the two commonly used RNA extraction methods and of the library construction protocols (rRNA depletion versus mRNA) on 1) the relative abundance of intronic reads and 2) on the estimation of gene expression values. Results: We benchmarked the rRNA depletion-based sequencing with a specific analysis of the cytoplasmic and nuclear transcriptome fractions, suggesting that the large majority of the intronic reads correspond to unprocessed nuclear transcripts rather than to independent transcriptional units. We show that Qiagen or TRIzol extraction methods retain differentially nuclear RNA species, and that consequently, rRNA depletion-based RNA sequencing protocols are particularly sensitive to the extraction methods. Conclusions: We could show that the combination of Trizol-based RNA extraction with rRNA depletion sequencing protocols led to the largest fraction of intronic reads, after the sequencing of the nuclear transcriptome. We discuss here the impact of the various strategies on gene expression and alternative splicing estimation measures. Further, we propose guidelines and a double selection strategy for minimizing the expression biases, without loss of information.

Description
The placenta has shown morphological and functional adaption in Meishan and Yorkshire pig breeds during late gestation. While the vast difference of uterine capacity and conceptus genotype between Western and Chinese pig breeds affects the pattern of placental development. Whether the placenta within Chinese pig breed also has similar adaptive changes is still unknown. So, we measured the weight and area of 80 Chinese indigenous Diannan small-ear pig placentas and further selected 6 placentas from extremely high and low litter size groups (HL and LL) for deep RNA-sequencing to detect the molecular basis relate to the observed placental phenotype difference.

Description
Most ribosomal proteins (RP) are regarded as essential, static components that only contribute to ribosome biogenesis and protein synthesis. However, emerging evidence suggests that RNA-binding RP are dynamic and can influence cellular processes by performing “extraribosomal”, regulatory functions involving binding to select, critical target mRNAs. We report here that the RP, Rpl22, and its highly homologous paralog, Rpl22-Like1 (Rpl22l1 or Like1), play critical, extraribosomal roles in embryogenesis. Indeed, they antagonistically control morphogenesis through developmentally-regulated localization to the nucleus where they modulate splicing of the pre-mRNA encoding smad2, an essential transcriptional effector of Nodal/TGF-ß signaling. During gastrulation, Rpl22 binds to intronic sequences of smad2 pre-mRNA and induces exon 9 skipping in cooperation with hnRNP-A1. This action is opposed by its paralog, Like1, which promotes exon 9 inclusion in the mature transcript. The nuclear roles of these RP in controlling morphogenesis represent a fundamentally different and paradigm-shifting mode of action for RP.

Description
The placenta is considered one of the candidate cell sources in cellular therapeutics because of a large number of cells and heterogenous cell population with myogenic potentials. We first analyzed myogenic potential of cells obtained from six parts of the placenta, i.e., umbilical cord, amniotic epithelium, amniotic mesoderm, chorionic plate, villous chorion (chorion frondosum), , and decidua basalis. Implantation of placenta-derived cells into dystrophic muscles of immunodeficient mdx mice restored sarcolemmal expression of human dystrophin. Co-existence of human and murine nuclei in one myotube and presence of human dystrophin in murine myotube suggests that human dystrophin expression is due to cell fusion between host murine myocytes and implanted human cells. In vitro analysis revealed that cells derived from amniotic mesoderm, chorionic plate, ,and villous chorion efficiently transdifferentiate into myotubes. These cells fused to C2C12 murine myoblasts by in vitro co-culturing, and murine myoblasts start to express human dystrophin after fusion. These results demonstrate that placenta-derived cells, especially extraembryonic mesodermal cells, have a myogenic potential and regenerative capacity of skeletal muscle. Determination of cell specification with the gene chip analysis revealed that each placental cell has a distinct expression pattern.
