Does cohesin regulate developmental gene expression in Drosophila ? [PDF]

open access: yesProceedings of the National Academy of Sciences, 2008
Cohesin is a conserved protein complex with a well documented role in providing stable but reversible connections between sister chromatids during both mitosis and meiosis. Cohesin consists of two long coiled-coil proteins (SMC1 and SMC3) and two non-SMC subunits (SCC1/Rad21 and SCC3/SA) that combine to form a ring-like structure.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Single gene analysis in yeast suggests nonequilibrium regulatory dynamics for transcription

open access: yesNature Communications
Fluctuations in the initiation rate of transcription, the first step in gene expression, ensue from the stochastic behavior of the molecular process that controls transcription.

Laminin receptors in the retina: sequence analysis of the chick integrin alpha 6 subunit. Evidence for transcriptional and posttranslational regulation. [PDF]

open access: yes, 1991
The integrin alpha 6 beta 1 is a prominent laminin receptor used by many cell types. In the present work, we isolate clones and determine the primary sequence of the chick integrin alpha 6 subunit.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Enhancer mediated regulation of developmental gene expression

open access: yesThe FASEB Journal, 2012
Cell‐fate transitions involve the integration of genomic information encoded by regulatory elements, such as enhancers, with cellular and signaling environments. Identification of genomic sequences that control human embryonic development represents a formidable challenge, as they are embedded within a vast non‐coding genomic space.

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Distinguishing epigenetic marks of developmental and imprinting regulation

open access: yesEpigenetics & Chromatin, 2010
Background The field of epigenetics is developing rapidly, however we are only beginning to comprehend the complexity of its influence on gene regulation.

Development of functional ectopic compound eyes in scarabaeid beetles by knockdown of orthodenticle [PDF]

open access: yes, 2017
Complex traits like limbs, brains, or eyes form through coordinated integration of diverse cell fates across developmental space and time, yet understanding how complexity and integration emerge from uniform, undifferentiated precursor tissues remains ...

Zebrafish churchill regulates developmental gene expression and cell migration [PDF]

open access: yesDevelopmental Dynamics, 2013
Background: Regulation of developmental signaling pathways is essential for embryogenesis. The small putative zinc finger protein, Churchill (ChCh) has been implicated in modulation of both TGF‐β and FGF signaling. Results: We used zinc finger nuclease (ZFN) mediated gene targeting to disrupt the zebrafish chch locus and generate the first chch ...
