Tripsacum-X-Maize Hybrids in Tripsacum Cytoplasm
… 82 chromosomes (72Td + 10Zm) in Tripsacum cytoplasm. Four backcrosses, with maize as the recurrent parent, produced an array of chromosomal types. The most common pathway for elimination of Tripsacum chromosomes was 2n = 82, 2n = 92, 2n = 56, 2n = 38, and 2n = 23 or 24 chromosomes. Plants …

Mechanics and dynamics of living mammalian cytoplasm
… for systems at thermal equilibrium. However, cytoplasm of a living cell operates far from equilibrium and thus, the applicability of passive microrheology in living cells is often questioned. Active microrheology methods have been successfully used to measure mechanics of living cells however, …

Anomalous diffusion of mRNA in the cytoplasm of HeLa cells
… of individual messenger RNA molecules in the cytoplasm of HeLa cells. RNAs are imaged in live cells via total internal reflection (TIRF) microscopy. In order to visualize individual RNA molecules expressing the MYH9 gene, they were labeled via MS2 stem loops bound to coat proteins tagged with …

First-passage time analysis of particle transport in the cytoplasm
… fluorescent tracer particles embedded in the cytoplasm. The analysis of such experiments typically involves computation of the mean-square displacement of the particles, and thus ignores the variation in how individual particles are transported by activity within the cell. Here, first-passage …

Linear and Non-Linear Mechanical Nature of a Living Mammalian Cytoplasm
Cytoplasm is a complex active material wherein numerous biochemical processes occur, which are critical for functioning of a cell. Many of the biological processes, such as cell migration, mechanotransduction, and cancer metastasis, involve mechanical processes and are critically regulated by cell …

Measurement of rapid protein diffusion in the cytoplasm by photoconverted intensity profile expansion
… at the level of a single protein, or in the cytoplasm as a whole, the diffusive mobility of proteins plays a key role in biological function. To measure protein diffusion in cells, researchers have developed multiple fluorescence microscopy methods, and have tested them rigorously. However, …

Overcoming the plasma membrane barrier to improve the efficiency of therapeutic delivery to the cellular cytoplasm
… delivery of molecular cargo directly into the cytoplasm of specific populations of target cells, through interactions of embedded multi-functional, multi-domain transmembrane targeting proteins that target cell-specific receptors. By opening direct routes to the cytoplasm, targeted …

Heterogeneity of injury in vasculitis: influence of anti neutrophil cytoplasm antibody IgG subclass and endothelial susceptibility.
This study examined IgG subclass in ANCA associated vasculitis and glomerular endothelial cell (GEC) phenotype predisposes to injury. Using the flow model, interaction of neutrophils with normal immunoglobulin subclasses was compared to interaction with subclasses of ANCA IgG. Neutrophils were …

Translocations of Actin to Nucleus and p21WAF1 to Cytoplasm after Treatment of HDF Cells with H2O2
목적 : 세포는 오랫동안 스트레스에 노출될 경우 조기노화가 유도된다. 이를 stress-induced premature senescence라 부른다. 자외선, 약물 또는 cytokine등 세포외의 자극에 의한 스트레스나 DNA 손상에 의한 스트레스에 의해 조기노화가 유도되는데, 이 경우 세포 내 활성 산소의 증가가 동반되는 것으로 알려져 있다. 본 연구에서는 human diploid fibroblast (HDF) 1차 배양체에 산화적 스트레스의 매개체의 일종인 H2O2를 한 번 또는 반복적으로 투여하여 유도되는 세포의 조기노화 …

The In Vitro Transgene Expression and In Vivo Transgene Integration of Condensed DNA Injected into the Cytoplasm of Murine Zygotes
… with MgCl<sub>2</sub> and injected into the cytoplasm of murine zygotes at three concentrations (100, 425 and 625 µg/ml). Zygotes injected with the highest concentration had the highest percentages of fluorescing embryos (44%), fluorescing morula and blastocysts (16.7%), and the lowest …

Reprogramming the expression of the double-stranded RNA mitovirus OnuMV1c from the mitochondria to the cytoplasm in the fungal pathogen Ophiostoma novo-ulmi
… enhanced hypovirus. RNA interference (RNAi) is a cytoplasmic process, and therefore in order to use OnuMV1c for RNAi the viral genome needed to be reprogrammed such that it could be expressed in the cytoplasm rather than the mitochondria. The objectives of my master’s research were to 1) …

ΦΩΣΦΟΔΙΕΣΤΕΡΟΛΥΤΙΚΗ ΔΡΑΣΗ ΣΕ ΚΥΤΤΑΡΟΠΛΑΣΜΑ ΣΥΚΩΤΙΟΥ ΠΟΝΤΙΚΟΥ C3HB. ΚΑΘΑΡΙΣΜΟΣ ΚΑΙ ΜΕΛΕΤΗ ΙΔΙΟΤΗΤΩΝ ΤΕΣΣΑΡΩΝ ΕΝΖΥΜΩΝ
THE ACID RIBONUCLEOLYTIC ACTIVITY OF MOUSE LIVER CYTOPLASM IS DUE TO 2 RIBONUCLEASES. THEY ARE LOW MOLECULAR WEIGHT ENZYMES THAT RESIST ACID CONDITIONS BUT ARE DESTROYED AT 100 K FOR 10 MIN . THE ENZYMES SHOW DIFFERENT PRETENCES TOWARDS END-LABELLED NATURAL SUBSTRATES (55 RNA). RNASE I SHOWS THE …

Distribution and Proportion of Immunoreactive Neuron Specific Enoclase Containing Cells in the Rat Pineal Gland
<p>The distribution and proportion of cytoplasm containing immunoreactive neuron specific enolase (NSE) in the rat pineal have been investigated. Step serial sections of the pineal glands of 7 male Sprague-Dawley rats were stained for NSE using an indirect immunoperoxidase method. The volumes of …

Nuclear accumulation of G-actin in cellular senescence: Reduced expressions of exportin 6 and Ran small G protein
… been known that actin is exclusively kept in the cytoplasm by exportin 1 (CRM1)-driven nuclear export. However, CRM1 has been reported to be not directly involved in actin export from vertebrate or Drosophila nuclei. On the other hand, exportin 6 (exp6) has been found as a novel family member from …

Inquiries into the subcellular localization of the glucocorticoid receptor.
… the glucocorticoid receptor (GR) resides in the cytoplasm existing in an inactive form complexed to heat shock proteins and immunophilins. Upon ligand addition, GR dissociates from the protein complex and transforms into an active free form that rapidly and completely translocates to the nucleus …
