Elongational Stresses and Cells [PDF]

open access: yesCells, 2021
Fluid forces and their effects on cells have been researched for quite some time, especially in the realm of biology and medicine. Shear forces have been the primary emphasis, often attributed as being the main source of cell deformation/damage in devices like prosthetic heart valves and artificial organs.

The Elongation of Ovococci [PDF]

open access: yesMicrobial Drug Resistance, 2014
The morphogenesis of ovococci has been reviewed extensively. Recent results have provided new insights concerning the mechanisms of elongation in ovoid bacteria. We present here the proteins involved in the elongation (firmly established and more or less hypothetical) and discuss the relationship between elongation and division of ovococci.

T‐armless tRNAs and elongated elongation factor Tu [PDF]

open access: yesIUBMB Life, 2007
AbstractMost tRNAs share a common secondary structure containing a T arm, a D arm, an anticodon arm and an acceptor stem. However, there are some exceptions. Most nematode mitochondrial tRNAs and some animal mitochondrial tRNAs lack the T arm, which is necessary for binding to canonical elongation factor Tu (EF‐Tu).

Transcription elongation [PDF]

open access: yesTranscription, 2017
This review is focused on recent progress in understanding how Escherichia coli RNAP polymerase translocates along the DNA template and the factors that affect this movement. We discuss the fundamental aspects of RNAP translocation, template signals that influence forward or backward movement, and host or phage factors that modulate translocation.

Elongation Factor TFIIS Prevents Transcription Stress and R-Loop Accumulation to Maintain Genome Stability [PDF]

open access: yes, 2019
Although correlations between RNA polymerase II (RNAPII) transcription stress, R-loops, and genome instability have been established, the mechanisms underlying these connections remain poorly understood.

The effect of additional sucrose on the value of tensile strength and elongation of chicken legs gelatin film

open access: yesJournal of Advanced Pharmaceutical Technology & Research, 2023
Gelatin is a clear, flavorless, and colorless biopolymer formed by the denaturation of collagen protein in animal tissues. Gelatin is an important ingredient in the manufacture of capsule shell films. The tensile strength and elongation values of gelatin

LARP7 suppresses P-TEFb activity to inhibit breast cancer progression and metastasis. [PDF]

open access: yes, 2014
Transcriptional elongation by RNA polymerase (Pol) II is essential for gene expression during cell growth and differentiation. The positive transcription elongation factor b (P-TEFb) stimulates transcriptional elongation by phosphorylating Pol II and ...

Tomato phyE is Required for Shade Avoidance in the Absence of phyB1 and phyB2.

open access: yesFrontiers in Plant Science, 2016
The phytochrome (phy) family of red and far-red photoreceptors provides plants with critical information about their surrounding environment and can signal downstream developmental and physiological changes.

Spt5 Cooperates with Human Immunodeficiency Virus Type 1 Tat by Preventing Premature RNA Release at Terminator Sequences [PDF]

open access: yes, 2002
The human immunodeficiency virus type 1 (HIV-1) Tat protein activates transcription elongation by stimulating the Tat-activated kinase (TAK/p-TEFb), a protein kinase composed of CDK9 and its cyclin partner, cyclin T1.
