Unveiling Structural Heterogeneity and Evolutionary Adaptations of Heteromultimeric Bacterioferritin Nanocages

open access: yesAdvanced Science, EarlyView.
This study explores the structural heterogeneity and evolutionary adaptations of heteromultimeric bacterioferritins. Hetero‐Bfrs, evolved from either a homo‐Bfr or Ftn by gene duplications, differ from homo‐Bfrs substantially in the mechanisms underpinning iron oxidation and reduction despite high similarity in overall structure.

Genetic behavior of Triticum aestivum–Dasypyrum villosum translocation chromosomes T6V#4S·6DL and T6V#2S·6AL carrying powdery mildew resistance

open access: yesJournal of Integrative Agriculture, 2017
: T6V#2S·6AL and T6V#4S·6DL translocation chromosomes developed from the cross of wheat and different Dasypyrum villosum accessions have good powdery mildew (PM) resistance, but their pairing and pyramiding behavior remains unclear. Results in this study

Somatic Pairing in Drosophila virilis Mitosis [PDF]

open access: yes, 1975
In neuroblast cells homologous chromosomes tend to pair during prophase of mitosis. Heterochromatic elements of homologous chromosomes are widely separated in very early prophase, at which time the euchromatin is poorly stained.

The Nuclear Receptor NR1B1/RARα Arrests the Differentiation of Anti‐Tumor Effector Cytotoxic T Cells

open access: yesAdvanced Science, EarlyView.
RARα is highly expressed by differentiated effector and exhausted T cells and exerts a negative effect on effector T cell differentiation and the associated trafficking receptor switch. Upregulated RARα levels decrease the nuclear histone acetylase (HAT) activity, and this suppresses the expression of key Teff transcription factor BATF and trafficking ...

Injectable pH Responsive Conductive Hydrogel for Intelligent Delivery of Metformin and Exosomes to Enhance Cardiac Repair after Myocardial Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
Injectable pH responsive conductive hydrogel for intelligent delivery of metformin and exosomes to alleviate myocardial ischemia‐reperfusion injury. The hydrogel responds to the weakly acidic microenvironment of ischemic injury and can significantly reduce the production of intracellular ROS and enhance cardiac conduction, thereby resisting apoptosis ...

INTERGENOMIC CHROMOSOME PAIRING IN ALLOHAPLOID HYBRIDS OF GENUS SOLANUM

open access: yesВавиловский журнал генетики и селекции, 2015
Intergenomic chromosome pairing was analyzed in unique allohaploid hybrids, which had been produced through a process of somatic hybridization followed by a haploidization procedure (in vitro androgenesis).

HNF3α Targets Nckap1l and Promotes Renal Fibrosis Following Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
Hepatocyte Nuclear Factor 3 alpha (HNF3α) is significantly upregulated in renal tubular epithelial cells of CKD patients and fibrotic mice. Deletion of HNF3α mitigates IRI‐induced renal fibrosis, while overexpression worsens it. HNF3α directly regulates NCK‐associated protein 1‐like (Nckap1l), whose overexpression exacerbates fibrosis.
