Exposure of embryonic stem cells to physiological concentrations of Δ9-THC remodels cellular metabolism across differentiation.

The growth of wild Drosophila larvae on fruits is promoted by a yeast releasing essential nutrients extracellularly or by a stable association with a nutrient-providing bacterium established by microbe–microbe interactions.

CFAP52 is a candidate for genetic diagnosing male infertility with defects of sperm head-tail connection and flagella development.

Experiments exploring the role of juvenile hormone during the life cycle of firebrat insects provide clues about the evolution of metamorphosis.

The psychoactive component of cannabis, ∆9-THC, affects cell growth and metabolism in early embryonic cell types in mice.

Dorsoventral gradients of transcription factors NFIA, B, and X impose epigenetic and transcriptional spatial restrictions to olfactory receptor expression.

Mesoderm-derived enteric neurons born in the post-natal vertebrates drive maturation and aging of the enteric nervous system.

Throughout oocyte maturation, there is a simultaneous elevation in the concentrations of Ca²⁺ and Zn²⁺, and the fertilization-induced Ca²⁺ oscillations cease under Zn²⁺-deficient conditions, implying an interplay between these ions, potentially at the IP₃R1 level that harbors a Zn²⁺-binding domain.

The maintenance of proper mitochondrial-associated endoplasmic reticulum membranes is crucial for preventing skeletal muscle atrophy to interact with the Notch signaling pathway.

Although complete mouse in vitro spermatogenesis can be achieved, failure of adult Leydig cell development, with accumulation of progesterone and estradiol, androstenedione deficiency, deregulation of steroidogenic, and steroid target gene expression, were highlighted in organotypic cultures, even with hCG.
