Aosta Valley animal cancer registry: A collaborative initiative for monitoring cancer burden in animals

Veterinary Record Open, Volume 13, Issue 1, June 2026.
Abstract Background Animal cancer registry data are important for monitoring animal health, for prevention and research in veterinary medicine, and for comparative oncology. Since people and animals share the same environment and are exposed to many common risk factors, cancer patterns in animals may have a sentinel function for human health.

Paracrine effects of oocyte secreted factors and stem cell factor on porcine granulosa and theca cells in vitro [PDF]

, 2003
Oocyte control of granulosa and theca cell function may be mediated by several growth factors via a local feedback loop(s) between these cell types. This study examined both the role of oocyte-secreted factors on granulosa and thecal cells, cultured ...

Potential Effects of Prepubertal Exposure to Perfluorooctane Sulfonic Acid on the First Wave of Folliculogenesis in Young CD‐1 Mice

Birth Defects Research, Volume 118, Issue 5, May 2026.
ABSTRACT Background Perfluorooctane sulfonic acid (PFOS) belongs to a group of synthetic chemicals referred to as per‐ and polyfluoroalkyl substances (PFAS) that are known to degrade slowly. Exposure to PFOS has been reported to cause birth defects and disrupt female sex hormone levels in mice.

RNA Modifications: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 5, May 2026.
Types of RNA modification. We have summarized the currently common types of RNA modifications, including ac4C, m6A, m1A, m5C, m3C, m7G, and ψ, and visually characterized their features through structural formulas. The characteristic structures are marked with a background color different from the background color.

Insights Into Bifenthrin Stereoisomers and Their Regulatory Implications

ChemistryOpen, Volume 15, Issue 5, May 2026.
Bifenthrin is a pyrethroid insecticide with two stereogenic centers, generating four stereoisomers with distinct physicochemical and electronic properties. A combined crystallographic and density functional theory study, supported by Hirshfeld surface, quantum theory of atoms in molecules, natural bond orbital, and reactivity descriptor analyses ...

Transcriptomic analysis of the effects exerted by curcumin on dihydrotestosterone-induced ovarian granulosa cells

Frontiers in Endocrinology
PurposeHyperandrogenism is a leading cause of developmental retardation in ovarian granulosa cells. Previous studies have indicated that curcumin significantly improves follicular dysplasia, a characteristic of the polycystic ovary syndrome.

A Decline in Follicle Cell Function Is a Major Driver of Drosophila Ovarian Aging

Aging Cell, Volume 25, Issue 5, May 2026.
Aging drives a progressive accumulation of defects in somatic follicle cells of the Drosophila ovary. These defects are accompanied by reduced tissue and genome integrity, altered transcriptional profiles, and disrupted germ‐soma coordination. Targeted overexpression of Atg8a in a subset of follicle cells mitigates these defects and preserves ...
