Placenta

The placenta is a vital organ that develops during pregnancy to provide nourishment, waste removal, and other important functions for the growing fetus.
It is composed of extraembryonic tissues and plays a crucial role in the healthy development of the baby.
Placenta research is critical for understanding pregnancy-related conditions and improving maternal and child health outcomes.
PubCompare.ai can optimize this research by helping scientists locate the most relevant protocols, identify the best methods and products, and enhnace reproducibility and accuracy in their placenta studies.

RNA was extracted from 1 × 106Smchd1+/+;EμMycTg/+ and Smchd1MD1/MD1;EμMycTg/+ lymphoma cells using Qiagen RNeasy Minikit as per the manufacturers instructions. Libraries were prepared using Illumina’s TruSeq RNA sample preparation kit as per the manufacturers instructions and submitted to the Australian Genome Research Facility for quality control, library preparation and sequencing on the Illumina HiSeq 2000 platform using 100 base, paired end or single-end reads. Base calling and quality scoring were performed using Real-Time Analysis (version 1.17.21.3) and FASTQ file generation and de-multiplexing using CASAVA (version 1.8.2). Reads from FASTQ files were aligned to the mouse genome (mm10) using Subread (version 1.10.5) (26 (link)) and summarized at the gene-level using the featureCounts procedure (27 (link)). Subsequent analysis was carried out using the ‘edgeR’ (28 (link)) and ‘limma’ (14 ) Bioconductor software. The counts were transformed into CPM to standardize for differences in library-size and filtering was carried out to retain genes with a baseline expression level of at least 0.5 CPM in three or more samples. Data were TMM normalized (3 (link)) and an MDS plot was generated (Figure 1B) before linear models using various weighting strategies (described below) were fitted to summarize over replicate samples. Moderated t-statistics were used to assess differential expression between Smchd1MD1/MD1 and Smchd1+/+ (wild-type) samples, with genes ranked according to their FDR (22 ). These data are available under GEO series accession number GSE64099.
Smchd1 has been shown to have a role in the regulation of clustered protocadherins and imprinted genes in diverse tissues including whole embryo, adult brain, embryonic fibroblasts, placenta and malignant and normal B cells (30 (link)–32 (link)). We obtained gene sets for these two classes of genes to use as true positives (TPs) in our analysis. To identify protocadherins, we used regular expression matching to look for this term in the gene name field of the annotation of the filtered data set, which returned eight genes (out of a total of 71 in the mouse genome). A comprehensive set of imprinted mouse genes was downloaded from http://www.mousebook.org/imprinting-gene-list and matched to the expressed genes in this data set using Gene Symbols. In total, 46 genes out of the 150 in the original list were matched.

Methylation profiles were calculated as described previously6 and are available from the HEP database/browser at www.epigenome.org. Kruskall-Wallis tests were used to determine differential methylation between tissues (T-DMRs), measuring the proportion of uncorrected p-values that were smaller 0.001 for all CpGs. As this test is insensitive to samples that were only measured in a single sample such as sperm and placenta, the obtained number of T-DMRs is unlikely to be overstated due to putative aberrant methylation within these samples. Some T-DMRs were experimentally validated by sequencing independent DNA samples. Equality between two groups (age and sex) was performed using Wilcoxon tests.
For the analysis of co-methylation, median methylation values were used over all technical replicates to minimize any skewing effect because of possible outliers. In addition, we excluded all CpGs where the methylation values derived from the forward and reverse reads of the same amplicon differed by more than 10%. Based on this criterion, 38% of CpGs were excluded from the analysis. As only one DNA strand was analysed following bisulfite conversion, no assessment of hemimethylation was possible in this case. Methylation changes were calculated based on the absolute methylation differences between CpG pairs of identical samples. To minimize a bias introduced by the amplicon selection, the analysis was performed using both, individual CpGs (window size 20,000bp) and CpGs of the same amplicons. Co-methylation of CpGs was described as a function of similar methylation levels over distance (in bp).
For scatter plots, equal amounts of measurements were binned and ranked by numerical order of the X-axis values, representing means of X- and Y- data. For box plots and histograms, data were binned according to the intervals indicated on the X-axis containing different numbers of measurements.

Both 5' and 3' RACE were performed on 12 human poly(A)+ RNAs (brain, heart, kidney, spleen, liver, colon, small intestine, muscle, lung, stomach, testis, placenta) using the BD SMART™ RACE cDNA amplification kit (BD BioScience-Clontech Catalogue No.634914, Mountain View, CA 95043, USA). Double-stranded cDNA synthesis and adaptor ligations to the synthesized cDNA were done according to the manufacturer's instructions. RACE fragments were separated on agarose gels and one or two strong single bands per gene purified and sequenced directly. Thus, successful RACE reactions appearing as a smear on the agarose gel would be discarded, therefore producing an approximate 54% success rate.

For Western blot analysis 20 μg of total protein extracted from cells lyzed with Laemmli-lysis buffer was used. Extracts were diluted in reducing sample buffer (Roth), subjected to SDS-PAGE and subsequently electrotransferred onto PVDF membrane (Pall). Immunostaining was performed with polyclonal antibodies reactive to CLDN6 (ARP) and beta-Actin (Abcam) followed by detection of primary antibodies with horseradish-peroxidase conjugated goat anti-mouse and goat anti-rabbit secondary antibodies (Dako).

Tissue lysates from up to five individuals were tested for each normal tissue type. No CLDN6 protein expression was detected in any of the normal tissues analyzed. In contrast to normal tissues, high expression of CLDN6 protein was detected in samples from ovarian cancer and lung cancer. CLDN6 expression was detected in NIH-OVCAR3 (ovarian cancer), MKN7 (gastric cancer), AGS (gastric cancer), CPC-N (SCLC), HCT-116 (colon cancer), FU97 (gastric cancer), NEC8 (testicular embryonal carcinoma), JAR (placental choriocarcinoma), JEG3 (placental choriocarcinoma), BEWO (placental choriocarcinoma), and PA-1 (ovarian teratocarcinoma).

SPF Sprague–Dawley rats (6~8 weeks age, 180~200 g weight) were purchased from Beijing Vital River Laboratory Animal Technology Co., Ltd. (SCXK 2012-0001, Beijing, China). Based on a previous report [25 (link)], we established an A2M-overexpression rat model via tail vein injection as previously described [26 (link)]. Briefly, on gestational day (GD) 8.5, rats (excluding non-pregnant rats) were injected with adenoviruses expressing A2M (OBiO Technology Co., Shanghai, China), and the sequencing results are shown in Additional file 1: Supplementary Result 1. We injected an adenoviral dose of approximately 1–2×109 pfu per animal, and the adenoviruses were dissolved in phosphate-buffered saline (PBS) to a total volume of 400 μl. The treated rats were sacrificed on GD19.5 (corresponding to the third trimester) for further study. The following parameters were assessed: blood pressure, blood flow, and proteinuria. The primary outcome of this study will be hypertension with blood pressure measurement. Secondary outcomes constitute blood flow, proteinuria, and histological analyses to measure the morphology and cell function of the spiral artery and placental vascular. For the rat samples, the pregnant rats were first euthanized to collect placentas and fetuses. According to Resource Equation Approach [27 (link)], a total of 20 rats were studied, the rats were randomly divided into two groups (n = 10 in each group): the control and A2M-overexpression groups (note: the rats used in this experiment came from at least three different modelling batches). Random numbers were generated using the standard = RAND() function in Microsoft Excel. Each rat was euthanized by cervical dislocation after the experiment. Experiments involving animals were performed in accordance with the ARRIVE guidelines. All experimental processes involving animal treatments were conducted in accordance with the procedures of the Ethics Committee for Animal Experimentation, Jinan University (approval number: 20210302-46).
