Heterogeneity in the kinetics of nuclear proteins and trajectories of substructures associated with heterochromatin.

Epigenetics & chromatin

Stixová L, Bártová E, Matula P, Daněk O, Legartová S, Kozubek S.
PMID: 21418567
Epigenetics Chromatin. 2011 Mar 18;4:5. doi: 10.1186/1756-8935-4-5.

BACKGROUND: Protein exchange kinetics correlate with the level of chromatin condensation and, in many cases, with the level of transcription. We used fluorescence recovery after photobleaching (FRAP) to analyse the kinetics of 18 proteins and determine the relationships between...

O-GlcNAcylation and Inflammation: A Vast Territory to Explore.

Frontiers in endocrinology

Baudoin L, Issad T.
PMID: 25620956
Front Endocrinol (Lausanne). 2015 Jan 09;5:235. doi: 10.3389/fendo.2014.00235. eCollection 2014.

O-GlcNAcylation is a reversible post-translational modification that regulates the activities of cytosolic and nuclear proteins according to glucose availability. This modification appears to participate in several hyperglycemia-associated complications. An important feature of metabolic diseases such as diabetes and obesity...

Chromatin Remodeling Protein SMAR1 Is a Critical Regulator of T Helper Cell Differentiation and Inflammatory Diseases.

Frontiers in immunology

Mirlekar B, Gautam D, Chattopadhyay S.
PMID: 28232831
Front Immunol. 2017 Feb 09;8:72. doi: 10.3389/fimmu.2017.00072. eCollection 2017.

T cell differentiation from naïve T cells to specialized effector subsets of mature cells is determined by the iterative action of transcription factors. At each stage of specific T cell lineage differentiation, transcription factor interacts not only with nuclear...

The Emerging Role of the Cytoskeleton in Chromosome Dynamics.

Frontiers in genetics

Spichal M, Fabre E.
PMID: 28580009
Front Genet. 2017 May 19;8:60. doi: 10.3389/fgene.2017.00060. eCollection 2017.

Chromosomes underlie a dynamic organization that fulfills functional roles in processes like transcription, DNA repair, nuclear envelope stability, and cell division. Chromosome dynamics depend on chromosome structure and cannot freely diffuse. Furthermore, chromosomes interact closely with their surrounding nuclear...

Sequential fractionation and isolation of subcellular proteins from tissue or cultured cells.

MethodsX

Baghirova S, Hughes BG, Hendzel MJ, Schulz R.
PMID: 26740924
MethodsX. 2015 Nov 07;2:440-5. doi: 10.1016/j.mex.2015.11.001. eCollection 2015.

Many types of studies require the localization of a protein to, or isolation of enriched protein from a specific cellular compartment. Many protocols in the literature and from commercially available kits claim to yield pure cellular fractions. However, in...

A variant of Runx2 that differs from the bone isoform in its splicing is expressed in spermatogenic cells.

PeerJ

Kanto S, Grynberg M, Kaneko Y, Fujita J, Satake M.
PMID: 27069802
PeerJ. 2016 Apr 04;4:e1862. doi: 10.7717/peerj.1862. eCollection 2016.

Background. Members of the Runx gene family encode transcription factors that bind to DNA in a sequence-specific manner. Among the three Runx proteins, Runx2 comprises 607 amino acid (aa) residues, is expressed in bone, and plays crucial roles in...

Immunolocalization of a nuclear protein bound to the sphere organelle during oogenesis and embryogenesis inPleurodeles waltl.

Roux's archives of developmental biology : the official organ of the EDBO

Boucher D, Loones MT, Pyne CK, Simon F, Abbadie C, Charlemagne J, Lacroix JC.
PMID: 28305890
Rouxs Arch Dev Biol. 1991 Aug;199(8):458-468. doi: 10.1007/BF01705782.

The distribution of a nuclear antigen ofPleurodeles waltl oocytes, recognized by the monoclonal antibody B24/1, has been studied during oogenesis and early embryonic development. In stage I oocytes the antigen was localized in the nucleoplasm and on two atypical...

An Intracellular Arrangement of Histoplasma capsulatum Yeast-Aggregates Generates Nuclear Damage to the Cultured Murine Alveolar Macrophages.

Frontiers in microbiology

Pitangui Nde S, Sardi Jde C, Voltan AR, Dos Santos CT, da Silva Jde F, da Silva RA, Souza FO, Soares CP, Rodríguez-Arellanes G, Taylor ML, Mendes-Giannini MJ, Fusco-Almeida AM.
PMID: 26793172
Front Microbiol. 2016 Jan 11;6:1526. doi: 10.3389/fmicb.2015.01526. eCollection 2015.

Histoplasma capsulatum is responsible for a human systemic mycosis that primarily affects lung tissue. Macrophages are the major effector cells in humans that respond to the fungus, and the development of respiratory disease depends on the ability of Histoplasma...

Weasner BP, Anderson J, Kumar JP.
PMID: 25580038
Proc Indian Natl Sci Acad B Biol Sci. 2004;(5):517-530.

One of the most exciting revelations in retinal biology is the realization that the molecules and mechanisms that regulate eye development have been conserved in all seeing animals including such diverse organisms as the fruit fly, mouse and man....

Thyroid Hormone Stimulates Renin Gene Expression Through the Thyroid Hormone Response Element.

Hypertension (Dallas, Tex. : 1979)

Kobori H, Hayashi M, Saruta T.
PMID: 11208763
Hypertension. 2001 Jan;37(1):99-104. doi: 10.1161/01.hyp.37.1.99.

-We previously reported that thyroid hormone stimulates renin synthesis in vivo and in vitro. Here, we analyzed the 5'-flanking sequence of the human renin gene for promoter activity responsive to thyroid hormone using Calu-6 cells, which secrete renin endogenously...
