Desaturation and chain elongation of [1-14C]mono-trans isomers of linoleic and α-linolenic acids in perfused rat liver

open access: yesJournal of Lipid Research, 1998
Trans polyunsaturated fatty acids are produced during heat treatment of oils, such as deodorization and frying. The detailed metabolic pathways of these trans isomers are not fully understood. In the present work, the desaturation and chain elongation of

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.

BET Bromodomain Proteins Function as Master Transcription Elongation Factors Independent of CDK9 Recruitment

open access: yesMolecules and Cells, 2017
SUMMARY Processive elongation of RNA Polymerase II from a proximal promoter paused state is a rate-limiting event in human gene control. A small number of regulatory factors influence transcription elongation on a global scale. Prior research using small-
