SUMMARY STATEMENT Proper force-balance generated by Kinesin-5 and Kinesin-14 is crucial for spindle bipolarity. Two fission yeast Kinesin-14s localize to different structures, thereby collaboratively producing inward forces against Kinesin-5-mediated outward force. ABSTRACT Kinesin motors play central roles in bipolar spindle assembly.

  • 4-6 Weeks Old Female C57BL/6 Mice Obtained from Jackson Labs Were Used for Cell Isolation
    Methods Mice: 4-6 weeks old female C57BL/6 mice obtained from Jackson labs were used for cell isolation. Female Foxp3-IRES-GFP reporter mice (1), backcrossed to B6/C57 background for 10 generations, were used for the isolation of naïve CD4 and naïve CD8 cells for the RNAseq experiments. The mice were housed in pathogen-free animal facility in the La Jolla Institute for Allergy and Immunology and were used according to protocols approved by the Institutional Animal Care and use Committee. Preparation of cells: Subsets of thymocytes were isolated by cell sorting as previously described (2), after cell surface staining using CD4 (GK1.5), CD8 (53-6.7), CD3ε (145- 2C11), CD24 (M1/69) (all from Biolegend). DP cells: CD4+CD8 int/hi; CD4 SP cells: CD4CD3 hi, CD24 int/lo; CD8 SP cells: CD8 int/hi CD4 CD3 hi, CD24 int/lo (Fig S2). Peripheral subsets were isolated after pooling spleen and lymph nodes. T cells were enriched by negative isolation using Dynabeads (Dynabeads untouched mouse T cells, 11413D, Invitrogen). After surface staining for CD4 (GK1.5), CD8 (53-6.7), CD62L (MEL-14), CD25 (PC61) and CD44 (IM7), naïve CD4+CD62L hiCD25-CD44lo and naïve CD8+CD62L hiCD25-CD44lo were obtained by sorting (BD FACS Aria). Additionally, for the RNAseq experiments, CD4 and CD8 naïve cells were isolated by sorting T cells from the Foxp3- IRES-GFP mice: CD4+CD62LhiCD25–CD44lo GFP(FOXP3)– and CD8+CD62LhiCD25– CD44lo GFP(FOXP3)– (antibodies were from Biolegend). In some cases, naïve CD4 cells were cultured in vitro under Th1 or Th2 polarizing conditions (3, 4).

In many (Wickstead et al., 2010). In general, N-kinesins and C-kinesins eukaryotes, spindle pole separation is driven by kinesin-5, which possess microtubule plus end- and minus end-directed motilities generates outward force. This outward force is balanced by respectively, whereas M-kinesins are microtubule depolymerases. antagonistic inward force elicited by kinesin-14 and/or dynein. In As proposed originally (Vale et al., 1985), kinesin molecules act as fission yeast, two kinesin-14 proteins, Pkl1 and Klp2, play an cellular power plants by generating directional forces across opposing role against the kinesin-5 motor protein Cut7. However, microtubules through repeated ATPase cycles. how the two kinesin-14 proteins coordinate individual activities During mitosis, a number of distinct kinesin molecules engage remains elusive. Here, we show that although deletion of either pkl1 with bipolar spindle assembly, thereby ensuring coordinated or klp2 rescues temperature-sensitive cut7 mutants, deletion of only chromosome segregation; these kinesins are collectively called pkl1 can bypass the lethality caused by cut7 deletion. Pkl1 is tethered mitotic kinesins (Sharp et al., 2000b; Tanenbaum and Medema, to the spindle pole body, whereas Klp2 is localized along the spindle 2010; Yount et al., 2015).

Genomic imprinting is an epigenetic phenomenon that causes a differential expression of paternally and maternally inherited alleles of a subset of genes (the so-called imprinted genes). Imprinted genes are distributed throughout the genome and it is predicted that about 1% of the human genes may be imprinted. It is recognized that the allelic expression of imprinted genes varies between tissues and developmental stages. The current study represents the first attempt to estimate a prevalence of imprinted genes within the total human transcriptome. In silico analysis of the normalized expression profiles of a comprehensive panel of 173 established and candidate human imprinted genes was performed, in 492 publicly available SAGE libraries.

We developed and validated a multivariate whole-blood mRNA- based predictor of melatonin phase which requires few samples.

  • Epigenetic Variability in Cells of Normal Cytology Is Associated with the Risk of Future Morphological Transformation
    Teschendorff et al. Genome Medicine 2012, 4:24 http://genomemedicine.com/content/4/3/24 RESEARCH Open Access Epigenetic variability in cells of normal cytology is associated with the risk of future morphological transformation Andrew E Teschendorff1*, Allison Jones2, Heidi Fiegl3, Alexandra Sargent4, Joanna J Zhuang1,2, Henry C Kitchener4 and Martin Widschwendter2* Abstract Background: Recently, it has been proposed that epigenetic variation may contribute to the risk of complex genetic diseases like cancer. We aimed to demonstrate that epigenetic changes in normal cells, collected years in advance of the first signs of morphological transformation, can predict the risk of such transformation. Methods: We analyzed DNA methylation (DNAm) profiles of over 27,000 CpGs in cytologically normal cells of the uterine cervix from 152 women in a prospective nested case-control study. We used statistics based on differential variability to identify CpGs associated with the risk of transformation and a novel statistical algorithm called EVORA (Epigenetic Variable Outliers for Risk prediction Analysis) to make predictions. Results: We observed many CpGs that were differentially variable between women who developed a non-invasive cervical neoplasia within 3 years of sample collection and those that remained disease-free. These CpGs exhibited heterogeneous outlier methylation profiles and overlapped strongly with CpGs undergoing age-associated DNA methylation changes in normal tissue. Using EVORA, we demonstrate that the risk of cervical neoplasia can be predicted in blind test sets (AUC = 0.66 (0.58 to 0.75)), and that assessment of DNAm variability allows more reliable identification of risk-associated CpGs than statistics based on differences in mean methylation levels.

  • Genome-Wide Association Study for Conformation Traits in Three Danish
    Le et al. Genet Sel Evol (2017) 49:12 DOI 10.1186/s12711-017-0289-2 Genetics Selection Evolution RESEARCH ARTICLE Open Access Genome‑wide association study for conformation traits in three Danish pig breeds Thu H. Le1,2*, Ole F. Christensen1, Bjarne Nielsen3 and Goutam Sahana1 Abstract Background: Selection for sound conformation has been widely used as a primary approach to reduce lameness and leg weakness in pigs. Identification of genomic regions that affect conformation traits would help to improve selection accuracy for these lowly to moderately heritable traits. Our objective was to identify genetic factors that underlie leg and back conformation traits in three Danish pig breeds by performing a genome-wide association study followed by meta-analyses. Methods: Data on four conformation traits (front leg, back, hind leg and overall conformation) for three Danish pig breeds (23,898 Landrace, 24,130 Yorkshire and 16,524 Duroc pigs) were used for association analyses. Estimated effects of single nucleotide polymorphisms (SNPs) from single-trait association analyses were combined in two meta- analyses: (1) a within-breed meta-analysis for multiple traits to examine if there are pleiotropic genetic variants within a breed; and (2) an across-breed meta-analysis for a single trait to examine if the same quantitative trait loci (QTL) segregate across breeds. SNP annotation was implemented through Sus scrofa Build 10.2 on Ensembl to search for candidate genes. Results: Among the 14, 12 and 13 QTL that were detected in the single-trait association analyses for the three breeds, the most significant SNPs explained 2, 2.3 and 11.4% of genetic variance for back quality in Landrace, overall conformation in Yorkshire and back quality in Duroc, respectively.
