Non-equilibrium dynamics of gene expression and the Jarzynski equality [PDF]

open access: yes, 2007
In order to express specific genes at the right time, the transcription of genes is regulated by the presence and absence of transcription factor molecules. With transcription factor concentrations undergoing constant changes, gene transcription takes place out of equilibrium.

Molecular mechanism for transcriptional regulation of the parathyroid hormone gene by Epiprofin

open access: yesThe FEBS Journal, EarlyView.
The secretion of parathyroid hormone (PTH) from the chief cells in the parathyroid glands is regulated by the concentration of extracellular calcium. Epiprofin (Epfn) expression is induced by NFATc2 in response to elevated serum calcium, and Epfn negatively regulates PTH production.

VIP contribution to the decidualization program: regulatory T cell recruitment [PDF]

open access: yes, 2014
During early pregnancy, the human uterus undergoes profound tissue remodeling characterized by leukocyte invasion and production of proinflammatory cytokines, followed by tissue repair and tolerance maintenance induction.

Krüppel-Like Factor 4 [PDF]

open access: yesCirculation Research, 2008
See related article, pages 1548–1557 The transcriptional response to vascular injury. The vascular response to injury is a dynamic and multifactorial process involving several cell types. As part of the vascular response to injury, normally quiescent, contractile vascular smooth muscle cells (VSMCs) respond to inflammatory and growth factors by ...

A time course analysis through diapause reveals dynamic temporal patterns of microRNAs associated with endocrine regulation in the butterfly Pieris napi

open access: yesMolecular Ecology, EarlyView.
Abstract Organisms inhabiting highly seasonal environments must cope with a wide range of environmentally induced challenges. Many seasonal challenges require extensive physiological modification to survive. In winter, to survive extreme cold and limited resources, insects commonly enter diapause, which is an endogenously derived dormant state ...

Role of noncoding RNA in vascular remodelling [PDF]

open access: yes, 2016
Purpose of review: Noncoding RNAs (ncRNAs), such as microRNAs (miRNAs) and long noncoding RNAs (lncRNAs) are becoming fundamentally important in the pathophysiology relating to injury-induced vascular remodelling.

Regulation of cGMP-dependent Protein Kinase Expression by Rho and Krüppel-like Transcription Factor-4 [PDF]

open access: yesJournal of Biological Chemistry, 2006
Type I cGMP-dependent protein kinase (PKG I) plays a major role in vascular homeostasis by mediating smooth muscle relaxation in response to nitric oxide, but little is known about the regulation of PKG I expression in smooth muscle cells. We found opposing effects of RhoA and Rac1 on cellular PKG I expression: (i) cell density-dependent changes in PKG

Unsupervised learning of transcriptional regulatory networks via latent tree graphical models [PDF]

open access: yesarXiv, 2016
Gene expression is a readily-observed quantification of transcriptional activity and cellular state that enables the recovery of the relationships between regulators and their target genes. Reconstructing transcriptional regulatory networks from gene expression data is a problem that has attracted much attention, but previous work often makes the ...

Mating system variation and gene expression in the male reproductive tract of Peromyscus mice

open access: yesMolecular Ecology, EarlyView.
Abstract Genes involved in reproduction often evolve rapidly at the sequence level due to postcopulatory sexual selection (PCSS) driven by male–male competition and male–female sexual conflict, but the impact of PCSS on gene expression has been under‐explored.

Annotation of Tribolium nuclear receptors reveals an evolutionary overacceleration of a network controlling the ecdysone cascade [PDF]

open access: yes, 2008
The Tribolium genome contains 21 nuclear receptors, representing all of the six known subfamilies. When compared to other species, this first complete set for a Coleoptera reveals a strong conservation of the number and identity of nuclear receptors in ...
