An F2(SxS.R-Edn3) population (n=173) was screened to identify rats having crossovers within the congenic region of RNO3 and six congenic substrains were developed that carry shorter segments of R-rat derived RNO3. Five of the six congenic substrains had significantly lower BP compared to the parental S rat. The lack of BP lowering effect demonstrated by the S.R(ET3x5) substrain and the BP lowering effect retained by S.R(ET3x2) substrain, together define the RNO3 BP QTL-containing region as approximately 4.64 Mb.

ABSTRACT Background In kidney transplant recipients, surveillance biopsies can reveal, despite stable graft function, histologic features of acute rejection and borderline changes that are associated with undesirable graft outcomes. Noninvasive biomarkers of subclinical acute rejection are needed to avoid the risks and costs associated with repeated biopsies. Methods We examined subclinical histologic and functional changes in kidney transplant recipients from the prospective Genomics of Chronic Allograft Rejection (GoCAR) study who underwent surveillance biopsies over 2 years, identifying those with subclinical or borderline acute cellular rejection (ACR) at 3 months (ACR-3) post-transplant. We performed RNA sequencing on whole blood collected from 88 indi- viduals at the time of 3-month surveillance biopsy to identify transcripts associated with ACR-3, developed a novel sequencing-based targeted expression assay, and validated this gene signature in an independent cohort.

It is increasing the evidence that also cells differ according to sex, a correlation still little studied and poorly considered when cells are used in scientific research. Specifically, our interest is on the sex-related dimorphism on the human mesenchymal stem cells (hMSCs) transcriptome. A systematic meta-analysis of hMSC microarrays was performed by using the Transcriptome Mapper (TRAM) software. This bioinformatic tool was used to integrate and normalize datasets from multiple sources and allowed us to highlight chromosomal segments and genes differently expressed in hMSCs derived from adipose tissue (hADSCs) of male and female donors.

    Genetic and Genomics Laboratory Tools and Approaches Meredith Yeager, PhD Cancer Genomics Research Laboratory Division of Cancer Epidemiology and Genetics [email protected] DCEG Radiation Epidemiology and Dosimetry Course 2019 www.dceg.cancer.gov/RadEpiCourse (Recent) history of genetics 2 Sequencing of the Human Genome Science 291, 1304-1351 (2001) 3 The Human Genome – 2019 • ~3.3 billion bases (A, C, G, T) • ~20,000 protein-coding genes, many non-coding RNAs (~2% of the genome) • Annotation ongoing – the initial sequencing in 2001 is still being refined, assembled and annotated, even now – hg38 • Variation (polymorphism) present within humans – Population-specific – Cosmopolitan 4 Types of polymorphisms . Single nucleotide polymorphisms (SNPs) . Common SNPs are defined as > 5% in at least one population . Abundant in genome (~50 million and counting) ATGGAACGA(G/C)AGGATA(T/A)TACGCACTATGAAG(C/A)CGGTGAGAGG . Repeats of DNA (long, short, complex, simple), insertions/deletions . A small fraction of SNPs and other types of variation are very or slightly deleterious and may contribute by themselves or with other genetic or environmental factors to a phenotype or disease 5 Different mutation rates at the nucleotide level Mutation type Mutation rate (per generation) Transition on a CpG 1.6X10-7 Transversion on a CpG 4.4X10-8 Transition: purine to purine Transition out of CpG 1.2X10-8 Transversion: purine to pyrimidine Transversion out of CpG 5.5X10-9 Substitution (average) 2.3X10-8 A and G are purines Insertion/deletion (average) 2.3X10-9 C and T are pyrimidines Mutation rate (average) 2.4X10-8 . Size of haploid genome : 3.3X109 nucleotides .

Posttranslational modification; SUMO; Sentrin/SUMO-specific proteases; Mass Spectrometry; Innate Immunity Abstract Post-translational modification of proteins by the addition of small ubiquitin-related modifier (SUMO) is a dynamic process, in which deSUMOylation is carried out by members of the Sentrin/SUMO-specific protease (SENP) family.
