Steroid Hormone Vitamin D: Implications for Cardiovascular Disease.

Circulation Research, 2018
Understanding of vitamin D physiology is important because about half of the population is being diagnosed with deficiency and treated with supplements. Clinical guidelines were developed based on observational studies showing an association between low ...

Species‐Specific Epigenetic Signature Associates With Heat Stress Tolerance in the Perennial Tree Species Populus

GCB Bioenergy, Volume 17, Issue 5, May 2025.
This research highlights the unique responses of perennial tree species, Populus trichocarpa, P. deltoides, and their F1 hybrid to heat stress after priming. P. deltoides demonstrated improved photosynthetic efficiency and distinct epigenetic signatures, while P.

A New DNA Sequences Vector Space on a Genetic Code Galois Field [PDF]

The final version of the paper is published in the journal: MATCH Commun. Math. Comput. Chem. Volume 54 (2005), number 1 , pp. 3-28., 2004
A new n-dimensional vector space of the DNA sequences on the Galois field of the 64 codons (GF(64)) is proposed. In this vector space gene mutations can be considered linear transformations or translations of the wild type gene. In particular, the set of translations that preserve the chemical type of the third base position in the codon is a subgroup ...

GCN5‐related histone acetyltransferase HOOKLESS2 regulates fungal resistance and growth in tomato

New Phytologist, Volume 246, Issue 3, Page 1217-1235, May 2025.
Summary The functions of histone acetyltransferases (HATs) in the genetic control of crop traits and the underlying mechanisms are poorly understood. We studied the function of tomato HOOKLESS2 (SlHLS2), a member of the GCN5 family of HATs, through genetic, molecular and genomic approaches. Tomato hls2 mutants generated through CRISPR‐cas9 gene editing

Functional characterization and unraveling the structural determinants of novel steroid hydroxylase CYP154C7 from Streptomyces sp. PAMC26508

Heliyon
This study characterized cytochrome P450 enzyme CYP154C7 from Streptomyces sp. PAMC26508, emphasizing its capability to hydroxylate steroids, especially at the 16α-position.

A Novel Lie Algebra of the Genetic Code over the Galois Field of Four DNA Bases [PDF]

arXiv, 2005
By starting from the four DNA bases order in the Boolean lattice, a novel Lie Algebra of the genetic code is proposed. Here, the principal partitions of the genetic code table were obtained as equivalent classes of quotient subspaces of the genetic code vector space over the Galois field of the four DNA bases.

Pollution, stress response, and obesity: A systematic review

Obesity Reviews, Volume 26, Issue 5, May 2025.
Summary Limited literature addresses the association between pollution, stress, and obesity, and knowledge synthesis on the associations between these three topics has yet to be made. Two reviewers independently conducted a systematic review of MEDLINE, Embase, and Web of Science Core Collection databases to identify studies dealing with the effects of

Host Metabolites in Asparagus–Fusarium Interaction: Mechanisms and Regulation

Plant Pathology, Volume 74, Issue 4, Page 923-942, May 2025.
Specific host metabolites regulate Fusarium pathogenicity by modulating fungal gene expression, growth, mycotoxin biosynthesis, enhancing asparagus defence responses and ultimately affecting disease severity. ABSTRACT Asparagus (Asparagus officinalis) is an important perennial vegetable crop cultivated worldwide.

Stress hormones predict hyperbolic time-discount rates six months later in adults [PDF]

Neuro Endocrinol Lett. 2010;31(5):616-621, 2011
Objectives: Stress hormones have been associated with temporal discounting. Although time-discount rate is shown to be stable over a long term, no study to date examines whether individual differences in stress hormones could predict individuals' time-discount rates in the relatively distant future (e.g., six month later), which is of interest in ...
