Paf1C regulates RNA polymerase II progression by modulating elongation rate
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance The factors that regulate RNA polymerase II (Pol II) elongation rate and processivity are poorly understood. Here, we show that the Paf1 complex (Paf1C) modulates Pol II elongation rate, and loss of Paf1 results in accumulation of Ser5P in ...

High-Speed and Low-Load Twin-Roll Casting of Al–5%Mg Strip
Metals, 2022 A conventional twin-roll caster usually casts strips at a speed slower than 2 m/min and a roll load greater than 2 kN/mm. A vertical-type high-speed twin-roll caster can cast aluminum alloy strips at a speed higher than 10 m/min and a roll load smaller ...

Elongation of Flare Ribbons [PDF]
The Astrophysical Journal, 2017 Abstract We present an analysis of the apparent elongation motion of flare ribbons along the polarity inversion line (PIL), as well as the shear of flare loops in several two-ribbon flares. Flare ribbons and loops spread along the PIL at a speed ranging from a few to a hundred km s−1.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

bioRxiv, 2019 eIF3 is a multi-subunit complex with numerous functions in canonical translation initiation. eIF3 was also found to interact with 40S and 60S ribosomal proteins and translation elongation factors, but a direct involvement in translation elongation has ...

Acta Societatis Botanicorum Poloniae, 2011 In this contribution we deal with a new mathematical description of the response of short-term coleoptile/hypocotyl expansion growth to temperature. Although the interest of both the bio-mechanical basis of elongation growth and temperature responses has

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Elongation of the Body in Eels [PDF]
Integrative and Comparative Biology, 2010 The shape of the body affects how organisms move, where they live, and how they feed. One body plan that has long engaged the interest of both evolutionary biologists and functional morphologists is axial elongation. There is a growing interest in the correlates and evolution of elongation within different terrestrial and aquatic vertebrate clades.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Acetylation on histone H3 lysine 9 mediates a switch from transcription initiation to elongation
Journal of Biological Chemistry, 2017 The transition from transcription initiation to elongation is a key regulatory step in gene expression, which requires RNA polymerase II (pol II) to escape promoter proximal pausing on chromatin.
