Linear signaling in the Toll-Dorsal pathway of Drosophila: activated Pelle kinase specifies all threshold outputs of gene expression while the bHLH protein Twist specifies a subset [PDF]

open access: yes, 2002
Differential activation of the Toll receptor leads to the formation of a broad Dorsal nuclear gradient that specifies at least three patterning thresholds of gene activity along the dorsoventral axis of precellular embryos.

An eIF4E-binding protein regulates katanin protein levels in C. elegans embryos. [PDF]

open access: yes, 2009
In Caenorhabditis elegans, the MEI-1-katanin microtubule-severing complex is required for meiosis, but must be down-regulated during the transition to embryogenesis to prevent defects in mitosis.

SERCA is critical to control the Bowditch effect in the heart [PDF]

open access: yes, 2018
The Bowditch effect or staircase phenomenon is the increment or reduction of contractile force when heart rate increases, defined as either a positive or negative staircase.

Ectopic A-lattice seams destabilize microtubules [PDF]

open access: yes, 2014
Natural microtubules typically include one A-lattice seam within an otherwise helically symmetric B-lattice tube. It is currently unclear how A-lattice seams influence microtubule dynamic instability.

Quantitative and Qualitative Analysis of Dynamic Cavernosographies in Erectile Dysfunction due to Venous Leakage [PDF]

open access: yes, 1989
Of 521 patients with erectile dysfunction in whom a multidisciplinary approach was used, 145 (27.8%) showed venous leakage as (concomitant) etiology of the impotence in dynamic cavernosography.

Increased Gene Expression of LITAF, TNF-α and BCL6 in Endometrial Tissues of Women with Endometriosis: A Case-Control Study [PDF]

open access: yesCell Journal
Objective: Endometriosis, as a common inflammatory chronic disease is characterized by endometrial tissue growthoutside the uterine cavity. It was reported that lipopolysaccharides (LPS) activate a transcription factor called LPSinduced tumor necrosis ...

Spatial and temporal information processing in the sea urchin embryo: modular and intramodular organization of the CyIIIa gene cis-regulatory system [PDF]

open access: yes, 1996
The CyIIIa cytoskeletal actin gene of Strongylocentrotus purpuratus is expressed specifically in the aboral ectoderm. In earlier work we identified a 2.3 kb cis-regulatory region that is necessary and sufficient for correct spatial and temporal ...
