Hypoxia Upregulates Estrogen Receptor β in Pulmonary Artery Endothelial Cells in a HIF-1α-Dependent Manner [PDF]
, 2018 17β-Estradiol (E2) attenuates hypoxia-induced pulmonary hypertension (HPH) through estrogen receptor (ER)-dependent effects, including inhibition of hypoxia-induced endothelial cell proliferation; however, the mechanisms responsible for this remain ...

Neurogenomic landscape associated with status‐dependent cooperative behaviour
Molecular Ecology, EarlyView.Abstract The neurogenomic mechanisms mediating male–male reproductive cooperative behaviours remain unknown. We leveraged extensive transcriptomic and behavioural data on a neotropical bird species (Pipra filicauda) that performs cooperative courtship displays to understand these mechanisms.

Plant Biotechnology Journal, EarlyView.Summary Winter dormancy and bud break are crucial to the viability, adaptability and yield of fruit trees, but not all metabolic activities or regulatory factors involved in maintaining and breaking dormancy are known. Here, winter buds, spanning from natural dormancy to bud break, were collected from ‘Cabernet Sauvignon’ grapevines maintained outdoors

Occurence of active layer optical properties on some Lasing characteristics dye-doped Ch LC [PDF]
arXiv, 2010 Effect of a planar texture quality and its thickness on lasing spectrums and thresholds in dye-doped cholesteric liquid crystal (CLC) of steroid type is explored. Transition from the qualitative planar texture to the poor texture quality is accompanied by change of characteristic mode structures and by shift of barycentre in the long-wave side and the ...

Human P450 CYP17A1: Control of Substrate Preference by Asparagine 202 [PDF]
, 2018 CYP17A1 is a key steroidogenic enzyme known to conduct several distinct chemical transformations on multiple substrates. In its hydroxylase activity, this enzyme adds a hydroxyl group at the 17α position of both pregnenolone and progesterone at ...

Light Quantity Impacts Early Response to Cold and Cold Acclimation in Young Leaves of Arabidopsis
Plant, Cell &Environment, EarlyView.ABSTRACT Plant reactions to stress vary with development stage and fitness. This study assessed the relationship between light and chilling stress in Arabidopsis acclimation. By analysing the transcriptome and proteome responses of expanding leaves subjected to varying light intensity and cold, 2251 and 2064 early response genes and proteins were ...

Characterization of a regulatory region of the steroid 21-hydroxylase gene.
Journal of Biological Chemistry, 1986 Steroid 21-hydroxylase is expressed at high levels in the adrenal gland, where it is required for the synthesis of mineralocorticoids and glucocorticoids. The cis-acting nucleotide sequences required for expression of murine 21-hydroxylase were assessed by stable transfection of Y1 adrenocortical tumor cells with 21-hydroxylase genes containing ...

Gut Microbiota Dysbiosis: Pathogenesis, Diseases, Prevention, and Therapy
MedComm, Volume 6, Issue 5, May 2025.ABSTRACT Dysbiosis refers to the disruption of the gut microbiota balance and is the pathological basis of various diseases. The main pathogenic mechanisms include impaired intestinal mucosal barrier function, inflammation activation, immune dysregulation, and metabolic abnormalities.
