Ethylene Response of Plum ACC Synthase 1 (ACS1) Promoter is Mediated through the Binding Site of Abscisic Acid Insensitive 5 (ABI5). [PDF]

open access: yes, 2019
The enzyme 1-amino-cyclopropane-1-carboxylic acid synthase (ACS) participates in the ethylene biosynthesis pathways and it is tightly regulated transcriptionally and post-translationally.

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Transcriptional and Post-transcriptional Regulation of Lignin Biosynthesis Pathway Genes in Populus

open access: yesFrontiers in Plant Science, 2020
Lignin is a heterogeneous polymer of aromatic subunits derived from phenylalanine. It is polymerized in intimate proximity to the polysaccharide components in plant cell walls and provides additional rigidity and compressive strength for plants ...

Noise processing by microRNA-mediated circuits: The Incoherent Feed-Forward Loop, revisited [PDF]

open access: yes, 2016
The intrinsic stochasticity of gene expression is usually mitigated in higher eukaryotes by post-transcriptional regulation channels that stabilise the output layer, most notably protein levels. The discovery of small non-coding RNAs (miRNAs) in specific

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Research progress on post-transcriptional dysregulation of mRNA in pathogenesis of Alzheimer's disease [PDF]

open access: yesJichu yixue yu linchuang, 2021
Post-transcriptional regulation of mRNA is an essential step from RNA transcription to gene translation, the process includes mRNA splicing, nuclear export, translation, and decay.

Stress Granules in the Post-transcriptional Regulation of Immune Cells

open access: yesFrontiers in Cell and Developmental Biology, 2021
Immune cell activation triggers transcriptional and translational programs eliciting cellular processes, such as differentiation or proliferation, essential for an efficient immune response.

Proteasome- and SCF-dependent degradation of yeast adenine deaminase upon transition from proliferation to quiescence requires a new F-box protein named Saf1p. [PDF]

open access: yes, 2006
In response to nutrient limitation, Saccharomyces cerevisiae cells enter into a nonproliferating state termed quiescence. This transition is associated with profound changes in gene expression patterns.

Dynamics of transcriptional and post-transcriptional regulation [PDF]

open access: yesBriefings in Bioinformatics, 2020
AbstractDespite gene expression programs being notoriously complex, RNA abundance is usually assumed as a proxy for transcriptional activity. Recently developed approaches, able to disentangle transcriptional and post-transcriptional regulatory processes, have revealed a more complex scenario.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...
